Disclosure of Invention
Technical problem to be solved by the application
It is sometimes desirable to install an air suspension (cab suspension) at a higher position without changing the height of the cab back beam. In this case, for example, it is conceivable to form a booster bracket for a booster cab suspension in a cross-sectional U shape that opens downward, and to mount the booster bracket so as to span a rear cab mount bracket of a cab back beam described in patent document 1 (hereinafter, simply referred to as a "cab back beam"). The protruding portions formed by the front and rear vertical plate portions and the upper plate portion are disposed and fixed to the cab back. However, since other members may be fixed to the vertical plate portions of the cab back beam, if the height-increasing bracket is disposed so as to cross the protruding portion of the cab back beam, it may be difficult to secure a region for fixing the other members. If the other member is fixed to the booster bracket, the other member is fixed to the cab back by the booster bracket, and therefore, it is necessary to firmly fix the booster bracket to the cab back, which may complicate the fixing work of the other member to the cab back.
Accordingly, the present disclosure is directed to providing the following cab suspension support configuration: the cab suspension can be mounted on the cab back beam in an elevated state while securing a fixed area of other components on the cab back beam.
Technical means for solving the technical problems
In order to solve the above-described problem, a first aspect of the present disclosure provides a cab suspension support structure for supporting a cab suspension from a vehicle body frame side, the cab suspension being configured to support a rear end portion of a cab from below to suppress vibration of the cab, the cab suspension support structure including a cab back beam, a bulkhead, and a height-increasing bracket having a substantially L-shaped cross section. The cab back beam has: the vehicle body frame includes a roof rail portion extending in the vehicle width direction above the vehicle body frame in a state intersecting the vertical direction, a roof rail front plate portion extending downward by bending from a front end side of the roof rail portion, and a roof rail rear plate portion extending downward by bending from a rear end side of the roof rail upper plate portion, and the cab rear rail is supported from below by the vehicle body frame. The diaphragm is placed on the upper surface of the beam upper plate portion. The height-increasing bracket having a substantially L-shaped cross section has a bracket upper plate portion disposed above the bulkhead and supported from below by the beam upper plate portion via the bulkhead, and a bracket vertical plate portion extending downward from one end edge of the bracket upper plate portion in the front-rear direction, from which the plate portion is brought into close proximity to or in contact with the one of the beam front plate portion or the beam rear plate portion, and is fixed to the cab rear beam and supports the cab suspension from below by the bracket upper plate portion.
In this configuration, the bulkhead is placed on the upper surface of the beam upper plate portion of the cab back beam, the bracket upper plate portion of the height-increasing bracket is disposed above the bulkhead, the cabin suspension is supported from below by the bracket upper plate portion via the bulkhead, and the cabin suspension is supported from below by the bracket upper plate portion. Therefore, the cab suspension (disposed at a position away upward from the beam upper plate portion) can be increased.
The height-increasing bracket is formed in a substantially L-shaped cross section having a bracket upper plate portion that supports the cab suspension from below, and a bracket vertical plate portion that extends downward from one end edge of the bracket upper plate portion in the front-rear direction and that approaches or contacts the plate portion of the one of the beam front plate portion and the beam rear plate portion from the one side. That is, since the front plate portion of the cab back beam or the plate portion on the other side in the front-rear direction of the rear plate portion is covered with the height-increasing bracket having a substantially L-shaped cross section, when the other member is fixed to the plate portion on the other side of the rear beam, it is possible to reliably prevent the height-increasing bracket from covering the fixing area for fixing the plate portion on the other side of the other member. Therefore, the fixing area of the other member can be secured to the plate portion on the other side of the cab back beam.
Thus, according to the above configuration, the cab back beam can be attached to the cab back beam in a state where the cab suspension is raised while securing a fixed area of the other member.
Further, since the bracket vertical plate portion of the height-increasing bracket extends downward from the one end edge of the bracket upper plate portion and approaches or contacts the one plate portion of the beam front plate portion or the beam rear plate portion from the one side, the rotation of the height-increasing bracket about the axis extending in the up-down direction can be prevented by the abutment of the bracket vertical plate portion and the one plate portion. Therefore, even when the cab suspension is fixed by rotating about the vertical axis extending with respect to the bracket upper plate portion of the height-increasing bracket, the rotation of the height-increasing bracket can be prevented when the cab suspension is fixed, and thus, the cab suspension fixing operation can be prevented from being complicated.
A 2 nd aspect of the present disclosure is the cab suspension support structure according to the 1 st aspect, which includes a reinforcing member. The reinforcement member is disposed below the other end edge portion extending in the vehicle width direction on the other side in the front-rear direction of the bracket upper plate portion, and is fixed to the other end edge portion of the bracket upper plate portion in a state extending in the vehicle width direction.
In the above-described structure, the reinforcement member is fixed to the other end edge portion of the bracket upper plate portion in a state extending in the vehicle width direction, and therefore the other end edge portion of the bracket upper plate portion can be reinforced by the reinforcement member. In this way, since the one side of the bracket upper plate portion is reinforced by the bracket vertical plate portion extending downward from the end edge of the one side, the other side of the bracket upper plate portion is reinforced by the reinforcing member, so that the strength of the bracket upper plate portion can be ensured.
A 3 rd aspect of the present disclosure is the cab suspension support structure of the 2 nd aspect, wherein the bulkhead and the reinforcing member are integrally formed.
In this configuration, the separator and the reinforcing member are integrally formed, so that the number of parts can be reduced.
Effects of the application
According to the present disclosure, the cab suspension can be attached to the cab back beam in an elevated state while securing a fixed area of other components on the cab back beam.

Detailed Description
An embodiment of the present disclosure is described below based on the drawings. IN each of the drawings, FR represents the front of the vehicle, UP represents the upper side, and IN represents the vehicle width direction inner side. In the following description, the front-rear direction refers to the front-rear direction of the vehicle, and the left-right direction refers to the left-right direction in a state of being directed toward the front of the vehicle.
As shown in fig. 1 and 2, the cab suspension support structure of the present embodiment is applied to a structure that supports the cab suspension 4 of the flathead vehicle 1 in which the cab 2 is disposed substantially above the engine 3. The cab 2 is movable between a normal position (position of the cab 2 shown in fig. 1) where the rear end lower portion of the cab 2 is supported from below, and an inclined position (not shown) where the rear end lower portion of the cab 2 is rotationally moved forward and upward from the normal position. The front end lower portion of the cab 2 is rotatably supported about a front cab mount 6 provided at the front end portion of the body frame 5. The rear end lower portion of the cab 2 is elastically supported from the vehicle body frame 5 side by a rear cab mount 10.
The body frame 5 has: left and right 1 pair of side members 7 disposed on both sides in the vehicle width direction below the vehicle 1 and extending in the front-rear direction; and a plurality of cross members 8 extending in the vehicle width direction between the left and right side members 7 and connecting the left and right side members 7 to each other. Only 1 cross beam 8 is shown in fig. 2.
The rear cab mount 10 has: an arched cab back beam 12 fixed to the left and right side members 7 by left and right side brackets 11; left and right 1 pair of cab suspensions 4 mounted on the upper surface of the cab back beam 12; a floating beam 13 fixed to the upper surface side of the left and right cab suspensions 4; and a striker 14 fixed to the left and right 1 pairs of floating beams 13. The left and right vertical brackets 11 are erected in a substantially vertical direction in a state where lower end portions thereof are fixed to the left and right side members 7. The upper end portions of the left and right vertical brackets 11 are fixed to both vehicle width direction end portions of the cab back beam 12. The cab back 12 is disposed above the body frame 5 and extends in the vehicle width direction. The left and right cab suspensions 4 are substantially cylindrical air suspensions in the present embodiment, and are attached to both vehicle width direction end portions of the cab back 12. The floating beam 13 extends in the vehicle width direction above the cab back beam 12, and is elastically supported by the cab back beam 12 by the left and right cab suspensions 4. The left and right striker 14 are symmetrically provided on the upper surface side of the floating beam 13 and protrude upward. The rear end lower portion of the cab 2 is provided with a pair of left and right cab lock brackets 17 corresponding to the left and right striker 14 of the rear cab mount 10. The left and right cab lock brackets 17 have locking devices (not shown) therein, and in a state in which the cab 2 is disposed at the normal position, the left and right striker 14 of the rear cab mount 10 is engaged and locked by the locking devices of the left and right cab lock brackets 17, so that the cab 2 is brought into a normal state (state shown in fig. 1) in which the cab is held at the normal position. When the lock of the lock device of the left and right cab lock brackets 17 is released, the cab 2 is movable from the normal position to the tilted position. The rear cab mount 10 in a normal state supports the rear end lower portion of the cab 2 from below by the left and right cab suspensions 4 and the like.
As shown in fig. 3, the cab back beam 12 includes: a flat plate-shaped beam upper plate portion 18 intersecting the vertical direction; a flat plate-shaped beam front plate portion 19 bent downward from the front end edge of the beam upper plate portion 18 and intersecting the front-rear direction; a flat plate-shaped beam rear plate portion 20 bent downward from the rear end edge of the beam upper plate portion 18 and intersecting the front-rear direction; a flat plate-shaped front flange portion 21 extending forward from the lower end edge of the beam front plate portion 19; and a flat plate-shaped rear flange portion 22 extending rearward from a lower end edge of the beam rear plate portion 20, the cab rear beam 12 being formed in a hat-shape in cross section. The cab back 12 of the present embodiment is formed in an arch shape in which the vehicle width direction central portion is curved upward than the vehicle width direction outer end portions. The left and right end portions of the cab back 12 are fixed to the upper end portions of the left and right vertical brackets 11, and are supported from below by the body frame 5 via the left and right vertical brackets 11 (see fig. 2). The left and right cab suspensions 4 are attached to the upper surface sides of the left and right end portions of the cab back 12 in a state of being raised upward.
In the present embodiment, the cab suspension support structure of the present disclosure is applied to a structure that is attached to the left end portion of the cab back beam 12 in a state in which the left cab suspension 4 is raised upward. Hereinafter, the left end portion of the cab back beam 12 will be referred to as "the vehicle width direction outer end portion of the cab back beam 12". A filter mounting bracket 23 for mounting a fuel filter (not shown) to the cab back 12 is fixed to the front surface of the center pillar front panel portion 19 at the vehicle width direction outer end portion of the cab back 12 by welding. The filter mounting bracket 23 is provided with a bolt through hole 24 for fixing the fuel filter. The left side cab suspension 4 is mounted on the upper surface side of the vehicle width direction outer end portion of the cab back 12 in a state of being raised by a reinforcement partition (partition, reinforcement member) 15 and a raising bracket 16. Hereinafter, the left cab suspension 4 will be referred to as "cab suspension 4" only.
As shown in fig. 4, bolt through holes (not shown) for fixing the height-increasing brackets 16 and suspension locking holes 27 for attaching the cab suspension 4 are formed in the vehicle width direction outer end portions of the beam upper plate portions 18 of the cab back beam 12.
As shown in fig. 4 to 7, the height-increasing bracket 16 is a member having a substantially L-shaped cross section, and includes a bracket upper plate portion 25 intersecting the vertical direction and a bracket rear plate portion (bracket vertical plate portion) 26 extending downward by bending from an end edge (rear end edge in the present embodiment) of the bracket upper plate portion 25 on one side in the front-rear direction, and is fixed to the cab rear beam 12. A plate-like reinforcing partition plate 15 described later is fixed to the lower surface side of the bracket upper plate portion 25. The bracket upper plate portion 25 is disposed above the beam upper plate portion 18 with the reinforcing bulkhead 15 interposed between the bracket upper plate portion and the upper surface of the beam upper plate portion 18 of the cab back beam 12. That is, the bracket upper plate portion 25 is disposed at a position (raised position) away upward from the beam upper plate portion 18 of the cab back 12 by the reinforcement partition plate 15. In a state where the height-increasing bracket 16 is fixed to the cab back 12, a front end edge portion (the other end edge portion) 25a of the bracket upper plate portion 25 is located slightly rearward of the front end edge portion 18a of the beam upper plate portion 18 and extends in the vehicle width direction, and the bracket back plate portion 26 is brought into proximity to or in contact with the rear surface of the beam back plate portion 20 of the cab back 12 from behind.
The bracket upper plate portion 25 is formed with a bolt through hole 28 for fixing the bracket upper plate portion 25 to the beam upper plate portion 18 and a suspension locking hole 29 for attaching the cab suspension 4. The bolt penetration holes 28 of the bracket upper plate portion 25 are formed at positions that communicate up and down with the bolt penetration holes of the beam upper plate portion 18. The suspension locking hole 29 of the bracket upper plate portion 25 is formed at a position vertically communicating with the suspension locking hole 27 of the beam upper plate portion 18. The suspension locking holes 27 and 29 of the beam upper plate 18 and the bracket upper plate 25 are formed in a shape in which 2 locking protrusions (not shown) protruding downward from the cab suspension 4 can be inserted from above.
The reinforcing partition 15 has the following two functions: as a spacer, a function of disposing the bracket upper plate portion 25 of the height-increasing bracket 16 at a position away upward from the beam upper plate portion 18 of the cab back beam 12; and as a reinforcing member for reinforcing the front end edge portion 25a of the bracket upper plate portion 25. That is, the reinforcing partition 15 is a reinforcing member/partition in which a reinforcing member and a partition are integrally formed. The reinforcing partition 15 is formed in a flat plate shape intersecting the vertical direction, and is formed in a substantially T-shape in plan view. The reinforcement spacer 15 is fixed to the bracket upper plate portion 25 in a state where its upper surface contacts the lower surface of the bracket upper plate portion 25. The reinforcing spacer 15 integrally has: a 1 st region 15a extending in the vehicle width direction below the front end edge 25a of the bracket upper plate 25; and a 2 nd region 15b extending rearward from a vehicle width direction center portion of the 1 st region 15 a. The 1 st region 15a is welded to the front end edge portion 25a of the bracket upper plate portion 25 in a linear manner in a state of being in contact with the lower surface of the front end edge portion 25a of the bracket upper plate portion 25 from below, thereby reinforcing the front end edge portion 25a of the bracket upper plate portion 25. The 2 nd region 15b has a bolt penetration hole 32 communicating with the bolt penetration hole 28 of the bracket upper plate portion 25, and is wire-welded to the bracket upper plate portion 25 in a state of contacting the lower surface of the bracket upper plate portion 25. The reinforcement spacer 15 is placed on the upper surface of the beam upper plate portion 18 of the cab back 12 while being fixed to the bracket upper plate portion 25 of the height-increasing bracket 16, and is fastened and fixed to the beam upper plate portion 18 together with the height-increasing bracket 16 by bolts 30. The lower surfaces of the 1 st region 15a and the 2 nd region 15b of the reinforcement spacer 15 are in surface contact with the upper surface of the beam upper plate portion 18 of the cab back beam 12. The 1 st region 15a and the 2 nd region 15b of the reinforcement spacer 15 are disposed at positions that do not interfere with the suspension locking holes 27, 29 of the beam upper plate portion 18 and the bracket upper plate portion 25.
When the height-increasing bracket 16 and the reinforcement spacer 15 are attached to the cab back 12 together, the bolts 30 are inserted and screwed in a state where the bolt through holes 28, 32 of the bracket upper plate portion 25 and the reinforcement spacer 15 are communicated with the bolt through holes of the beam upper plate portion 18 of the cab back 12. In the present embodiment, the bolt 30 is fastened in a state in which the stopper member 31 for controlling the movement of the cab suspension 4 in the direction intersecting the up-down direction is placed above the bracket upper plate portion 25.
When the cab suspension 4 is mounted on the cab back 12, 2 locking projections (not shown) of the cab suspension 4 are inserted into the suspension locking holes 29 of the bracket upper plate 25 and the suspension locking holes 27 of the beam upper plate 18 of the cab back 12 from above the bracket upper plate 25 of the height-increasing bracket 16. By rotating the cab suspension 4 (rotating about the axis extending in the vertical direction) from this state, the 2 locking projections of the cab suspension 4 are locked in the suspension locking holes 27 and 29 of the beam upper plate portion 18 and the bracket upper plate portion 25, and the cab suspension 4 is mounted on the cab back 12. In a state where the cab suspension 4 is attached to the cab back 12, the lower surface of the cab suspension 4 contacts the upper surface of the bracket upper plate portion 25 of the height-increasing bracket 16.
In the above-described configuration, the lower surface of the reinforcement spacer 15 is in contact with the upper surface of the beam upper plate portion 18 of the cab back 12, and the lower surface of the bracket upper plate portion 25 of the height-increasing bracket 16 is in contact with the upper surface of the reinforcement spacer 15, and the lower surface of the cab suspension 4 is in contact with the upper surface of the bracket upper plate portion 25. That is, the cab suspension 4 is attached to the cab back 12 in a state of being separated upward (raised) from the upper surface of the beam upper plate portion 18 of the cab back 12 by the reinforcement partition plate 15 and the bracket upper plate portion 25 of the raising bracket 16. Therefore, the cab suspension 4 can be raised (placed at a position away upward from the beam upper plate portion 18).
The height-increasing bracket 16 has a bracket upper plate portion 25 that supports the cab suspension 4 from below and a bracket rear plate portion 26 that extends downward from a rear end edge of the bracket upper plate portion 25 to approach or contact the beam rear plate portion 20 from behind, and is formed in a substantially L-shaped cross section. That is, since the front surface of the beam front plate portion 19 of the cab back beam 12 is not covered with the height-increasing bracket 16, the height-increasing bracket 16 can be reliably prevented from covering a fixing area provided on the front surface of the beam front plate portion 19 for fixing other components (the filter mounting bracket 23 in the present embodiment). Therefore, a fixing area for fixing the other members can be secured to the front surface of the beam front plate portion 19.
Therefore, according to the present embodiment, the cab back beam 12 can be attached in a state in which the cab suspension 4 is raised while securing the fixing area of the other members in the beam front plate portion 19 of the cab back beam 12.
Further, since the bracket rear plate portion 26 of the height-increasing bracket 16 approaches or contacts the rear surface of the beam rear plate portion 20 of the cab rear beam 12 from the rear, the rotation of the height-increasing bracket 16 about the axis extending in the up-down direction can be prevented by the abutment of the bracket rear plate portion 26 and the beam rear plate portion 20. Therefore, even when the cab suspension 4 is mounted on the cab back 12 and rotated about the axis extending in the up-down direction, the rotation (co-rotation) of the height-increasing bracket 16 can be prevented when the cab suspension 4 is mounted, and the fixing operation of the cab suspension 4 can be prevented from being complicated.
The 1 st region 15a of the reinforcement spacer 15 is welded to the front end edge portion 25a of the bracket upper plate portion 25 in a line shape in a state of being in contact with the lower surface of the front end edge portion 25a of the bracket upper plate portion 25 of the elevation bracket 16 from below, thereby reinforcing the front end edge portion 25a of the bracket upper plate portion 25. In this way, since the rear end edge side of the bracket upper plate portion 25 is reinforced by the bracket rear plate portion 26, and the front end edge portion 25a side of the bracket upper plate portion 25 is reinforced by the 1 st region 15a of the reinforcing partition plate 15, the strength of the bracket upper plate portion 25 can be ensured. Accordingly, in order to secure a fixing area for fixing the other members on the front surface of the beam front plate portion 19, the height-increasing bracket 16 is formed in a cross-sectional L shape instead of a cross-sectional U shape that opens downward. Thus, even when it is difficult to secure the strength of the distal end edge portion 25a side of the bracket upper plate portion 25, the strength of the distal end edge portion 25a side of the bracket upper plate portion 25 can be secured by reinforcing the 1 st region 15a of the partition plate 15.
In addition, the reinforcing spacer 15 has the following two functions: as a spacer, a function of disposing the bracket upper plate portion 25 of the height-increasing bracket 16 at a position away upward from the beam upper plate portion 18 of the cab back beam 12; and as a reinforcing member for reinforcing the front end edge portion 25a of the bracket upper plate portion 25. In this way, since the reinforcing partition plate 15 is a reinforcing member/partition plate in which the reinforcing member and the partition plate are integrally formed, the number of parts can be reduced unlike the case where the reinforcing member and the partition plate are formed separately.
In the present embodiment, the reinforcement spacer 15 is provided with both the function as a spacer for disposing the bracket upper plate portion 25 of the height-increasing bracket 16 at a position spaced upward from the beam upper plate portion 18 of the cab back beam 12 and the function as a reinforcement member for reinforcing the front end edge portion 25a of the bracket upper plate portion 25, but the present application is not limited thereto. For example, the 1 st region 15a and the 2 nd region 15b of the reinforcing separator 15 may be formed separately, and the 1 st region 15a may function as the reinforcing member and the 2 nd region 15b may function as the separator. In this case, the 1 st region 15a functioning as the reinforcing member may be formed to be thinner than the 2 nd region 15b functioning as the separator.
In the present embodiment, the reinforcing spacer 15 is formed in a substantially T shape in a plan view, but the shape of the reinforcing spacer 15 is not limited to this, and various shapes can be applied.
In the present embodiment, the filter mounting bracket 23 is assumed to be another member fixed to the beam front plate portion 19 of the cab back beam 12, but the other member is not limited thereto.
In the present embodiment, the height-increasing bracket 16 is formed in a substantially L-shaped cross section having the bracket upper plate portion 25 and the bracket rear plate portion (bracket vertical plate portion) 26 in order to secure a fixing area for fixing other members (the filter mounting bracket 23) to the front surface of the beam front plate portion 19 of the cab rear beam 12. For example, in the case where other members are fixed to the rear surface of the beam rear plate portion 20 of the cab rear beam 12, the height-increasing bracket 16 may be formed to have a substantially L-shaped cross section including the bracket upper plate portion 25 and the bracket front plate portion (bracket vertical plate portion).
In the present embodiment, the cab back beam 12 is formed in a hat-shaped cross section, but the present application is not limited to this, and may be any shape having at least the beam upper plate portion 18, the beam front plate portion 19, and the beam back plate portion 20.
In the present embodiment, the cab back 12 is formed in an arch shape in which the vehicle width direction central portion is curved upward than the vehicle width direction outer end portion, but the present application is not limited to this, and other shapes may be used as long as the cab suspension 4 can be supported from below.
In the present embodiment, the cab suspension 4 is an air suspension, but may be another type of suspension as long as the rear end side of the cab 2 can be elastically supported.
In the present embodiment, the cab suspension 4 is mounted by rotating about an axis extending in the up-down direction with respect to the cab back beam 12, but the mounting method of the cab suspension 4 is not limited to this.
In the present embodiment, the cab suspension support structure of the present disclosure is applied to a structure in which the left cab suspension 4 is attached to the left end portion of the cab back beam 12, but may be applied to a structure in which the right cab suspension 4 is attached to the right end portion of the cab back beam 12.
The present disclosure has been described based on the embodiments, but the present disclosure is not limited to the embodiments, and can be appropriately modified without departing from the scope of the present disclosure. That is, other embodiments, examples, and techniques of operation, etc., made by those skilled in the art based on this embodiment are intended to be included within the scope of the present disclosure.
The present application is based on Japanese patent application No. 2020, month 5 of 2020 (Japanese patent application No. 2020-017926), the contents of which are incorporated herein by reference.
