Description

  The present invention relates to a clutch pedal assembling apparatus in which a turnover spring is interposed between a mounting bracket and a pedal arm.

  The clutch pedal has an urging force that will surely return the pedal arm to its initial position when the foot is removed (hereinafter referred to as urging in the returning direction), and an urging force that assists the pedal arm when it is depressed to some extent (the urging direction force). ) In many cases (for example, Patent Document 1), the turnover spring is interposed between the mounting bracket and the pedal arm. The turnover spring includes a coil spring that changes the posture in accordance with the depression of the pedal arm and changes the direction in which the contracting force is applied to the pedal arm, thereby switching the return direction bias and the depression direction bias. As shown in FIG. 1, there is a configuration including a winding spring (torsion coil spring) that uses a torsional force (see Patent Document 1 [0022] and FIG. 1).

JP 2005-119547 A

  A turnover spring comprising a winding spring (hereinafter referred to as a “turnover spring” in the present invention, which refers to a construction comprising a winding spring) is engaged with a mounting bracket and a pedal arm at both ends, and the pedal arm is depressed a little. The pedal arm is surely returned to the initial position by being slightly deformed and constantly applying a return direction bias to the pedal arm. However, it is difficult to slightly deform the turnover spring and interpose it between the mounting bracket and the pedal arm. For this reason, conventionally, a turnover spring that does not apply a load, that is, an undeformed turnover spring is interposed between the mounting bracket and the pedal arm, and the initial position is adjusted by pushing the pedal arm with a bolt or the like. Was deformed.

  The deformation of the turnover spring as described above requires adjusting means such as a bolt for pushing the pedal arm. However, depending on the arrangement of the clutch pedal and the layout of the driver's seat, there are many cases where appropriate adjustment means cannot be successfully provided. In these exceptional cases, a turnover spring is provided between the mounting bracket and the pedal arm. In the assembling process, the turnover spring must be deformed. However, it is difficult to slightly deform the turnover spring by human power. Therefore, in order to develop an assembling device that enables easy and reliable assembling of the clutch pedal while slightly deforming the turnover spring, an investigation was made.

What has been developed as a result of the study is a device that assists in assembling a clutch pedal having a turnover spring interposed between the mounting bracket and the pedal arm, the supporting base for fixing the mounting bracket, and the supporting base. A tilting table that can be tilted by a tilting shaft within a rotating surface of a pedal arm that is pivotally attached to a mounting bracket that is fixed in position, and a push rod that moves forward and backward from the tilting table toward the mounting bracket along the rotating surface of the pedal arm, It consists of a push rod advance / retreat means provided on the tilting table, and engages one end of the turnover spring with the mounting bracket, the push rod is provided with a push protrusion, and the turn over spring extends from the front end to the push protrusion. Support the other end from below, and press the other end of the turnover spring with the pushing projection to turn the turn An assembling device of a clutch pedal deforming over bar spring.

A preferred assembling device includes a support base for fixing the position of the mounting bracket, a tilting table that can be tilted by a tilting shaft within a rotation surface of the pedal arm that is pivotally attached to the mounting bracket fixed to the support base, and the pedal arm. A mounting bracket comprising: an advancing / retreating table that advances and retreats from the tilting table toward the mounting bracket along the rotation surface; a table advancing / retreating means provided on the tilting table; and a push rod protruding from the advancing / retreating table toward the mounting bracket. One end of the turnover spring is engaged with the push rod , and the push rod is provided with a push projection, and the other end of the turn over spring is supported from the lower side between the front end and the push projection. The turnover spring is deformed by pushing an end.

A more preferred assembly device is a device for assisting assembly of a clutch pedal having a turnover spring interposed between a mounting bracket and a pedal arm, and a support base for fixing the position of the mounting bracket; and the support base A tilting table that can be tilted by a tilting shaft within a rotating surface of a pedal arm that is pivotally attached to a mounting bracket that is fixed in position, an advancing and retracting table that moves forward and backward from the tilting table toward the mounting bracket along the rotating surface of the pedal arm, and consists of a table moving means provided on the tilting table, a pushing rod for advancing and retracting toward the mounting bracket from the reciprocating table along the plane of rotation of the pedal arm, a push rod moving means which is provided on the reciprocating table, mounted brackets engaged with one end of the turnover spring, pushing rod is provided with a pushing projection, the front end Supporting the other end of the turnover spring from below between al the push protrusion, wherein a configuration in which the pushing projection by pressing the other end of the turnover spring deforming the turnover spring.

  The clutch pedal assembling apparatus according to the present invention is configured such that one end of a turnover spring is engaged with a mounting bracket fixed to a support base, and the push rod is advanced by a push rod according to an advance / retreat table or a push rod advancing / retreating means. After the other end of the spring is supported from below and the pedal arm is pivotally attached to the mounting bracket, the turnover spring is deformed by advancing and retreating the table and the push rod by the table advancing and retreating means, thereby rotating the pedal arm. And engage the other end of the turnover spring. At the stage where the push rod supports the other end of the turnover spring, the tilting table is pushed by the restoring force of the turnover spring through the push rod, but the other end of the turnover spring is engaged with the pedal arm. When combined, the restoring force of the turnover spring is not transmitted to the pushing rod, and the tilting table is tilted by the action of the moment of the pushing rod that has advanced, and the pushing rod is detached from the other end of the turnover spring.

  In the assembling apparatus using the advance / retreat table, the advance / retreat table may be attached to the tilting table via a slider extending along the rotation surface of the pedal arm. The table advancing / retreating means may be constituted by a cylinder for advancing / retreating the rod along the rotating surface of the pedal arm, and connecting the rod to the advancing / retreating table. Similarly, the push rod advance / retreat means may be constituted by a cylinder that advances and retracts the push rod along the rotation surface of the pedal arm. When the cylinder is used in a two-stage configuration, the rod of the first cylinder may be connected to a support column erected on the advance / retreat table, and the second cylinder may be fixed to the support column.

  In addition, as described above, the tilting table naturally tilts when the other end of the turnover spring is separated from the push rod, but in order to reliably remove the push rod from the other end of the turnover spring, the tilt table is It is good to forcibly tilt by a table tilting means provided on the support base. The table tilting means is a coil spring interposed between the support base and the tilting table on the side closer to the mounting bracket from the tilting shaft, and the coil spring extends when the push rod pushes the other end of the turnover spring. A configuration in which the tilting table is tilted by contracting the other end of the turnover spring away from the push rod can be exemplified. The table tilting means is a coil spring interposed between the support base and the tilting table on the side far from the tilting shaft to the mounting bracket, and the coil spring is used when the push rod pushes the other end of the turnover spring. The tilting table may be tilted by contracting and extending when the other end of the turnover spring is separated from the push rod.

  The clutch pedal assembling apparatus according to the present invention makes it possible to easily and reliably assemble the clutch pedal while slightly deforming the turnover spring. Since the conventional clutch pedal is assembled without deforming the turnover spring and the turnover spring is slightly deformed later, there is a design restriction that requires a structure that causes the deformation of the turnover spring. . However, in the present invention, the turnover spring can be deformed when assembled, so that the clutch pedal can be assembled without any restriction on the design. Thus, the present invention has a secondary effect of increasing the degree of freedom in designing the clutch pedal.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 are side views showing a procedure for assembling the clutch pedal 2 by the assembling apparatus 1 of the present invention. FIG. 1 shows a stage where the mounting bracket 21 is fixed to the support base 11, and FIG. 2 shows a turnover spring. FIG. 3 shows a stage in which the pedal arm 22 is pivotally attached to the mounting bracket 21, with one end 231 of the 23 engaged with the mounting bracket 21 and the other end 232 of the turnover spring 23 supported by the extended push rod 16. 4 is a stage in which the rod 131 is extended and the advance / retreat table 14 is advanced, and at the same time, the pedal arm 22 is rotated downward, and FIG. 5 is the other end of the turnover spring 23 deformed by the advanced push rod 16. FIG. 6 shows that the other end 232 of the deformed turnover spring 23 moves away from the push rod 16 and is fully engaged with the pedal arm 22. A stage, and FIG. 7 retracts the reciprocating table 14, representing respectively the stage where retract the push rod 16 at the same time. In each figure, the rotation surface of the pedal arm 22 is parallel to the drawing. For convenience of explanation, the majority of the mounting bracket 21 is shown in phantom lines in FIG.

  As shown in FIG. 1, for example, the assembling apparatus 1 of the present invention supports the tilting table 12 to be tilted on a support table 111 integrated with a support base 11 for fixing the position of the mounting bracket 21 via a tilting shaft 121. The advancing / retreating table 14 is provided via the slider 141 provided on the tilting table 12, and the rod 131 of the cylinder 13 attached to the tilting table 12 via the fixing bracket 123 is connected to the column 142 standing on the advancing / retreating table 14. The push rod 16 is extended from the cylinder 15 fixed to the column 142. The cylinder 13 and the cylinder 15 are not particularly limited as long as the rod 131 or the push rod 16 can be advanced and retracted, respectively.

  The push rod 16 is provided with a push projection 161 projecting in the forward / backward orthogonal direction (the orthogonal direction in the drawing in FIG. 1) on the upper surface side at a position slightly recessed from the front end. Accordingly, the push rod 16 supports the other end 232 of the turnover spring 23 from below from the front end to the push projection 161, and pushes the other end 232 of the turnover spring 23 by the push projection 161 to push the turnover spring. 23 can be deformed. Such a push rod 16 is placed in a substantially horizontal position so that the other end 232 of the turnover spring 23 (see FIG. 2 and subsequent figures) with one end 231 engaged with the mounting bracket 21 is securely pushed. It is desirable for the height to coincide with the end 232. Therefore, for example, the height of the mounting base 21 relative to the support base 11 or the support base 11 may be adjusted by a height adjusting means (not shown).

  In the assembling apparatus 1 of this example, a handle 122 that allows an operator to adjust the tilting posture of the tilting table 12 is attached to the tilting table 12. The handle 122 is used, for example, when the push rod 16 is forcibly tilted when the other end 232 of the turnover spring 23 is separated, or when the push rod 16 is raised to make the push rod 16 substantially horizontal again. . In this example, in order to restrict the tilt in the direction in which the push rod 16 is lifted, a restriction projection 125 is provided between the support table 111 and the tilt table 12 on the side far from the tilt shaft 121 to the mounting bracket 21. Further, as a table tilting means, when a coil spring 124 is interposed between the support table 111 and the tilting table 12 on the side closer to the mounting bracket 21 from the tilting shaft 121, as indicated by a virtual line in FIG. The handle 122 can be omitted. The coil spring 124 may be provided between the support table 111 and the tilting table 12 on the side far from the tilting shaft 121 to the mounting bracket 21 (not shown). In addition, instead of the handle 122, the table tilting means may be configured using an external driving means.

  Assembling of the clutch pedal 2 using the assembling apparatus 1 of this example is performed according to the following procedure. First, as shown in FIG. 1, the mounting bracket 21 is fixed to the upper surface of the support base 11. Although the posture of the mounting bracket 21 is arbitrary, in this example, the mounting bracket 21 is arranged such that the support base 11 side is the front of the vehicle, the upper support base 11 is the rear of the vehicle, and the extending direction of the support table 111 is the vehicle floor surface direction. The posture is determined. The position of the mounting bracket 21 to the support base 11 may be fixed by using a mounting bolt hole (not shown) or the like when the mounting bracket 21 is fixed to the vehicle. When the mounting bracket 21 cannot be directly fixed to the support base 11, an auxiliary jig interposed between the mounting bracket 21 and the support base 11 may be used.

  Next, as shown in FIG. 2, the bent end 21 231 of the turnover spring 23 is inserted into the engaging hole 211 of the mounting bracket 21 and engaged with the mounting bracket 21 fixed to the support base 11. The cylinder 15 is actuated to extend the pushing rod 16, and the bent other end 232 of the turnover spring 23 is placed between the front end and the pushing projection 161 and supported. At this stage, the turnover spring 23 is not deformed, and the tilting table 12 is supported by the turnover spring 23 and the pushing rod 16 and only maintains a substantially horizontal posture. At the same time, the pedal arm 22 is pivotally attached to the mounting bracket 21 via a rotating shaft, and is held in a state where it is lifted upward by, for example, an operator. The pivoting of the pedal arm 22 with respect to the mounting bracket 21 may be performed by using a pin or the like as usual, and the assembly of the mounting bracket 21 and the pedal arm 22 is thereby completed.

  When the cylinder 13 is operated with the push rod 16 supporting the other end 232 of the turnover spring 23 and the rod 131 starts to be extended, as shown in FIG. Then, the cylinder 15 and the push rod 16 begin to advance together. As a result, when the pushing protrusion 161 advances in accordance with the pushing rod 16, the pushing protrusion 161 starts to push the spring main body 233 extending from the other end 232 of the turnover spring 23, and the position of the turnover spring 23 is relatively fixed. The turnover spring 23 starts to be deformed so that the other end 232 approaches the one end 231. At this stage, the turnover spring 23 generates a restoring force, and the pushing rod 16 maintains a substantially horizontal posture while balancing the restoring force and the pushing force of the rod 131 by the cylinder 13.

  Thus, when the turnover spring 23 is deformed and the other end 232 moves to the rotation path of the engaging portion 221 of the pedal arm 22 as shown in FIG. 4, the pedal arm is seen as shown in FIG. 22 is slightly lowered to start engaging the engaging portion 221 with the other end 232 of the turnover spring 23. When the engaging portion 221 of the pedal arm 22 and the other end 232 of the turnover spring 23 are firmly engaged, the restoring force of the turnover spring 23 is no longer transmitted to the push rod 16, and FIG. As can be seen, the push rod 16 leaves the turnover spring 23 and tilts according to the tilting table 12. Finally, when the cylinder 15 shortens the push rod 16 and at the same time the cylinder 13 retracts the advance / retreat table 14, the assembly of the clutch pedal 2 is completed as seen in FIG.

  The clutch pedal 2 immediately after the assembly is in a state where the pedal arm 22 is depressed, and when the pedal arm 22 is returned to the initial position, the other end 232 of the turnover spring 23 moves away from the one end 231 and is engaged. It looks as if it comes off the part 221. However, since the turnover spring 23 swings around the one end 231 engaged with the engagement hole 211 of the mounting bracket 21, the pedal arm 22 is engaged after being engaged with the engagement portion 221 of the pedal arm 22. Even if the return to the initial position where it contacts the restriction surface 212 of the mounting bracket 21, the turnover spring 23 always maintains a slightly deformed state while changing the posture with respect to the engagement hole. Thus, according to the present invention, the clutch pedal 2 can be assembled with the turnover spring 23 slightly deformed interposed between the mounting bracket 21 and the pedal arm 22 in a simple and reliable procedure.
