Description of the Related Art As a conventional general pin slide type disc brake used for vehicles such as automobiles, in order to guide the caliper body in the axial direction of the disc during braking, the disc brake side of the caliper body and the rotation side of the disc. 2 on the outgoing side
There is known a structure in which a caliper support arm of a caliper bracket is supported via a slide pin of a book, for example, Japanese Patent Laid-Open No. 6-294424 and Japanese Patent Laid-Open No. 55-15592.
In JP-A-8, the number of slide pins is set to three or three or more to increase the support rigidity of the caliper body and suppress the tilting of the caliper body due to drag torque.
It has been proposed to stably support the weight of the caliper body.

[0003]

The above-described slide pin is provided so as to project from either one of the caliper body and the caliper bracket, and the other has a guide hole for accommodating the slide pin. As the number increases, the alignment between the slide pin and the guide hole becomes more difficult, and high precision is required for processing and assembly.

Further, it is inevitable that the caliper body and the caliper bracket during braking will be deformed or tilted due to the braking torque or the dragging torque from the friction pad, but at the same time, the caliper body and the caliper bracket will be attached to the slide pin and the guide hole provided therein. Also, there is an influence of bending deformation and the like, and when the number of slide pins is increased, smooth sliding of the caliper body may be hindered.

The present invention has been made in view of the above circumstances, and an object of the present invention is to effectively suppress the deformation and tilting of the caliper body while suppressing the number of slide pins to a small number, and also to reduce the caliper body. It is an object of the present invention to provide a caliper body support structure for a pin slide type vehicle disc brake, which is capable of smoothly sliding in the disc axial direction.

[0006]

In order to achieve the above-mentioned object, the first aspect of the present invention is to provide a function of a caliper body connected to both sides of the bridge portion by straddling the bridge portion of the caliper body to the outside of the disc rotor. Portion and reaction portion are disposed on one side portion and the other side portion of the disc rotor, and from the caliper bracket fixed to the vehicle body at the one side portion of the disc rotor, the disc turn-in side and the turn-out side of the bridge portion. A pair of caliper support arms projecting outside the disc rotor in the direction of the reaction part with the side in between, and slide in the disc axial direction on both the caliper support arms and the disc entry / exit side of the action part. A pin and a guide hole for accommodating the slide pin are provided in combination to support the caliper body so as to be slidable in the disc axial direction, and the disc is interposed between the action portion and the reaction portion. In a disc brake for a pin slide type vehicle in which a pair of friction pads are arranged to face each other with a crawler in between, and a torque receiving portion for supporting a braking torque from the friction pads is provided on both of the caliper support arms so as to face each other. A third slide pin in the disc axial direction is provided in either one of the bracket and the action portion, and a third guide hole for accommodating the third slide pin is provided in the other, and a set of the third slide pin and the third guide hole is provided. The alignment is offset from the disk radial direction line connecting the rotation center of the disk rotor and the pad pressing center of the caliper body to the disk spilling side, and the gap between the guide pin and the guide hole on the disk shunting side is set to The gap between the third guide pin and the third guide hole is larger than the gap between the guide pin and the guide hole on the disc entry side. Set to.

According to the second aspect of the present invention, the bridge portion of the caliper body is laid over the outside of the disc rotor, and the action portion and the reaction portion of the caliper body connected to both sides of the bridge portion serve as one side portion of the disc rotor. A reaction portion outside the disc rotor, sandwiching the disc turn-in side and turn-out side of the bridge portion from a caliper bracket that is disposed on the other side and fixed to the vehicle body at one side of the disc rotor. A pair of caliper support arms projecting in the same direction are extended, and the tips of both caliper support arms are connected by tie bars. The slide pin and the guide hole for accommodating the slide pin are provided in combination to support the caliper body so as to be slidable in the disc axial direction and to react with the acting portion. And a pair of friction pads sandwiching the disc rotor between them, and a torque receiving portion for supporting a braking torque from the friction pad facing the caliper support arm. In, in either one of the caliper bracket and the acting portion, a third slide pin in the disc axial direction,
A third guide hole for accommodating the third slide pin is provided on the other side, and a combination of the third slide pin and the third guide hole connects the rotation center of the disc rotor and the pad pressing center of the caliper body. Offset from the disc radial direction line to the disc payout side, and the gap between the guide pin and the guide hole on the disc payoff side is defined as the gap between the third guide pin and the third guide hole and the guide pin on the disc payout side. Set larger than the gap between the guide holes.

Elastic bushes may be attached to the slide pins on the disc feeding side of the first aspect of the invention and the slide pins of the disc feeding side of the second aspect to fill the gaps with the guide holes.

[0009]

In the pin slide type disc brake structure in which the torque receiving portion is provided on the caliper support arm, the braking torque generated on the friction pad is transmitted to the caliper support arm on the disc feeding side. For this reason, the caliper support arm on the disc payout side is controlled by the braking torque to the tip side of the disc rotor other side portion where the caliper bracket support rigidity is low, compared to the base portion side of the disc rotor one side portion where the caliper bracket support rigidity is high. Although the caliper body is tilted largely in the disc payout direction, and the caliper body is tilted through the slide pin and the guide hole on the disc payout side, the tip of the caliper support arm is not connected by a tie bar. By setting the gap between the slide pin on the feed side and the guide hole to be larger than the gaps of the other two sets, when the caliper support arm on the disc feed side is deformed by the braking torque as described above, this deformation The gap between the slide pin on the disc extension side and the guide hole will be absorbed, so that the caliper support arm will not be deformed. Hardly transmitted, so that the behavior of the caliper body can be suppressed as much as possible.

Further, when full braking from a high speed or excessive braking force deforms the caliper support arm on the disc payout side more than usual and the braking torque is transmitted to the slide pin on the disk payout side. The third slide pin, which is offset from the radial line of the disc to the disc extension side, supports the caliper body with high rigidity near the slide pin on the disc extension side, so the braking torque from the caliper support arm is effective. The tilting of the caliper body is suppressed as much as possible.

Further, in the structure of the second invention in which the tip end portion of the caliper support arm is connected by the tie bar, the deformation of the caliper support arm on the disk payout side due to the braking torque is passed through the slide pin and the guide hole on the disk payout side, and the caliper body is passed through. It is also transmitted to the caliper support arm on the disc turn-in side through the tie bar, so that the caliper body moves so that the disc turn-in side on the action part side and the disc turn-out side on the reaction part side approach the disc rotor. It acts to tilt it. The deformation of the caliper support arm is large on the side of the disc that directly receives the braking torque, and attenuates slightly on the side of the disc that is pulled through the tie bar. Therefore, the caliper body is subjected to non-uniform stress, but by setting the gap between the slide pin on the disc entry side and the guide hole to be larger than the gaps of the other two sets,
Since the gap between the slide pin and the guide hole absorbs the deformation of the caliper support arm on the disk entry side, the caliper body tilts as a whole, but uneven stress is less likely to act.

In the caliper body according to the first and second aspects of the present invention, the slide pin and the guide hole having a large gap on the disk entry side or the entry side reduce the weight on the disk entry side or the entry side of the caliper body. As the caliper body slides in the disc axial direction by the line contact, the remaining two sets of slide pins and the guide holes guide each other, so that the caliper body can be slid well and the slide pins and the guide holes It eliminates the need for high precision in processing and assembly.

Further, in the first and second aspects of the present invention, the braking reaction force from the friction pad pushes the action portion and the reaction portion back in the direction opposite to the disc direction, so that the caliper body is formed into a V shape with the bridge portion as a fulcrum. When an attempt is made to open and deform, the third slide pin offset to the disc payout side on which the braking torque from the caliper support arm on the disc payout side acts,
The deformation of the action portion is effectively prevented.

The sliding pins on the disk feeding side of the first invention and the sliding pins on the disk feeding side of the second invention are provided with elastic bushes for filling the gaps between the respective guide holes, so that they can be run or braked. Initially, the slide pin does not rattle or generate a contact noise.

At both ends of 3, the pair of caliper support arms 3b, 3c projecting toward the action portion 7b while straddling the outer side of the disc rotor 2 and sandwiching the disc entry side and extension side of the bridge portion 7c of the caliper body 7.
Has been extended. Stepped torque receiving portions 3d, 3d are provided on the opposite surfaces of the caliper support arms 3b, 3c so as to be divided on both sides of the disc rotor 2.
Bag-shaped guide holes 9 and 10 are formed inside c to open toward the action portion side, and a disc connecting the rotation center of the disc rotor 2 and the pad pressing center P of the caliper body 7 is formed on the caliper bracket 3. The third slide pin 6 is provided between the radial line R and the vehicle body mounting hole 3a on the disc extension side.
Is projected in the direction opposite to the disc.

The caliper body 7 has an action portion 7a provided on one side of the disc rotor 2 and a reaction portion 7b provided on the other side of the disc rotor 2, and these are provided outside the disc rotor 2. It is composed of a bridge portion 7c that straddles and connects. A cylinder hole 11 opening to the disk rotor side, a union hole 12 and a bleeder hole 13 opening in a bottom wall 7d of the cylinder hole 11, and three attachments projecting parallel to the side surface of the disk rotor 2 are attached to the action portion 7a. Arm 7
e, 7f and 7g are provided, and the reaction portion 7b is integrally formed with a pair of reaction force claws 7h and 7h.

The cylinder hole 8 has a cup-shaped piston 14
Is inserted into the bottom wall 7 of the piston 14 and the cylinder hole 11.
A hydraulic chamber 15 is defined between the hydraulic chamber 15 and d. Further, the above-mentioned slide pins 4 and 5 are provided on the mounting arms 7e and 7f on the disc entry side and the delivery side so as to project toward the reaction portion using the mounting bolts 16, and the third slide of the caliper bracket 3 is further provided. The intermediate mounting arm 7g protruding to the same position as the pin 6 is provided with a bag-shaped third guide hole 17 opened toward the disk rotor side, and the caliper body 7 is provided on the disk entry and exit sides. The slide pins 4 and 5 are inserted into the guide holes 9 and 10 of the caliper support arms 3b and 3c, and the third slide pin 6 of the caliper bracket 3 is housed in the third guide hole 17 in the middle, and as described above, Supported slidably in the direction.

The gap between the slide pin 5 on the disc feed side and the guide hole 10 is the gap between the slide pin 4 and the guide hole 9 on the disc feed side, and between the third slide pin 6 and the third guide hole 17. It is set larger than the gap. Also,
An annular elastic bush 18 that fills a gap with the guide hole 10 is fitted to the tip-side small-diameter shaft portion 5a of the slide pin 5 on the disc delivery side. The guide hole 10 is prevented from rattling or generating a contact noise.

The friction pad 8 includes a lining 19 which is in sliding contact with the side surface of the disk rotor 2 and caliper support arms 3b and 3b.
It is composed of a metal back plate 20 that is locked to c. Ear pieces 20a, 20a are provided on both sides of the back plate 20, and each friction pad 8 locks the ear pieces 20a, 20a on the torque receiving portions 3d, 3d of the caliper support arms 3b, 3c. And is slidably suspended on the torque receiving portions 3d, 3d in the disc axial direction.

When the braking operation is performed with such a configuration, the pressurized hydraulic fluid is supplied from the union hole 12 to the hydraulic chamber 15, and the piston 14 advances toward the disc rotor 2 to cause friction on the action portion 7a side. The pad 8 is pushed, and the lining 19 of the pad 8 is pushed to one side surface of the disc rotor 2. Next, this reaction causes the caliper body 7 to move in the direction of the acting portion 7a, so that the reaction force claws 7h and 7h move to the reacting portion 7b.
Side friction pad 8 is pushed, and lining 1 of said pad 8
9 is pressed against the other side surface of the disc rotor 2 to perform a braking action.

The friction pads 8 during braking are dragged in the disc spilling direction by the sliding contact between the disc rotor 2 and the linings 19, 19, and the side end faces of the back plates 20 on the disc spilling side are torque receiving portions. The braking torque generated in the friction pads 8, 8 by contacting the 3d, 3d is transmitted to the caliper support arm 3c on the disc feeding side.

For this reason, in the caliper support arm 3c on the disc payout side, the tip end side, which has a low support rigidity by the caliper bracket 3, is largely tilted in the disc payout direction by the braking torque, and further, the slide pin 5 and the guide on the disc payout side are guided. Although the caliper body 7 is tilted through the hole 10, in the present embodiment, the gap between the slide pin 5 on the disc feeding side and the guide hole 10 is set larger than the other two sets, so that the disc Even if the caliper support arm 3c on the delivery side is tilted by the braking torque, the elastic bush 18 is not used in normal braking.
However, the caliper body 7 is hardly tilted.

Further, the caliper support arm 3c on the disc feeding side is provided by full braking at high speed and excessive braking force.
When the braking torque acts on the slide pin 5 on the disc feed side, the disc tilts from the disc radial direction line R to the disc feed side. Offset added to 3rd
Since the slide pin 6 supports the slide pin 5 on the disk feeding side with high rigidity near the vehicle body mounting hole 3a,
The braking torque from the caliper support arm 3c is effectively supported, and tilting of the caliper body 7 is suppressed as much as possible.

Further, during the above-mentioned braking, the friction pads 8, 8
The braking reaction force from acts to push back the action portion 7a and the reaction portion 7b in the direction opposite to the disc rotor direction, and the caliper body 7 tries to open and deform in a V shape with the bridge portion 7c as a fulcrum. The above-mentioned third slide pin 6 offset to the disc extension side of the caliper body 7 effectively prevents the action portion 7a from being deformed.

FIG. 4 shows another embodiment of the present invention, in which the tips of the caliper support arms 3b and 3c projecting toward the reaction portion side are connected by a tie bar 3e, and the slide pin 4 on the disc turn-in side. And the guide hole 9 are set to be larger than the gap between the slide pin 5 and the guide hole 10 on the disc feeding side and the gap between the third slide pin 6 and the third guide hole 17 near the disc feeding side. At the same time, the annular elastic bush 1 is attached to the small diameter shaft portion 4a of the slide pin 4 on the disc entry side.
8 is fitted to fill the gap with the guide hole 10, and other structures such as the third slide pin 6 and the third guide hole 17 are the same as those in the above-described embodiment.

In the braking according to the present embodiment, the deformation of the caliper support arm 3c on the disc payout side due to the braking torque is transmitted to the caliper body 7 through the slide pin 5 and the guide hole 10 on the disc payout side, and the tie bar is used. It is also transmitted to the caliper support arm 3b on the disk entry side through 3e, and the caliper body 7 is tilted so that the disk entry side on the action portion 7a side and the disk entry side on the reaction portion 7b side approach the disc rotor 2. It acts to let it do. The deformations of the caliper support arms 3b and 3c are large on the disk circling side that directly receives the braking torque, and are small on the disk circling side towed through the tie bar 3e. However, in the present embodiment, the slide pin 4 on the disc entry side is different from the slide pin 4 in the present embodiment.
The gap between the slide pin 4 and the guide hole 9 absorbs the deformation of the caliper support arm 3b on the disc turn-in side by setting the gap between the guide hole 9 and the guide hole 9 larger than the other two sets. Although the caliper body 7 tilts as a whole, uneven stress is less likely to act.

Therefore, in the present embodiment, the slidability of the caliper body 7 can be well ensured, and the durability of the caliper body 7 can be improved. Further, the third slide pin 6 offset from the disc radial direction R to the disc extension side is located in the vehicle body mounting hole 3a (see FIG. 2), and the third slide pin 6 from the caliper support arm 3c together with the slide pin 5 on the disc extension side. Supports braking torque effectively.

Further, the caliper support arm 3b on the disc entry side is subjected to full braking at high speed and excessive braking force.
Even if the disk tilts more than the gap between the slide pin 4 and the guide hole 9,
And the third slide pin 6 offset from the radial line R of the disc to the disc feeding side effectively support the braking torque from the caliper support arm 3c on the disc feeding side with high rigidity. The tilting of the caliper body 7 can be suppressed as much as possible.

Although the third slide pin is provided on the caliper bracket side and the third guide hole is provided on the caliper body side in both of the above-described embodiments, the present invention can be set in reverse.

[0032]

According to the first aspect of the present invention, the third slide pin in the disc axial direction is provided on either one of the action portions of the caliper bracket and the caliper body, and the third guide hole for accommodating the third slide pin is provided on the other. The combination of the third slide pin and the third guide hole is offset to the disc spill-out side from the disc radial direction line connecting the rotation center of the disc rotor and the pad pressing center of the caliper body, and the guide on the disc spill-out side is provided. By setting the gap between the pin and the guide hole to be larger than the gap between the third guide pin and the third guide hole and the gap between the guide pin and the guide hole on the disc feed-in side, the caliper support arm on the disc feed-out side is Even if the caliper tilts with the braking torque, the caliper body can be hardly tilted during normal braking, and the caliper body can be slid easily. It can be secured to.

Further, in the second invention having a structure in which the tip end portion of the caliper support arm is connected by a tie bar, a third slide pin in the disc axial direction is provided on either one of the action portions of the caliper bracket and the caliper body, and the other is provided on the other.

Offset to the delivery side, and set the gap between the guide pin and the guide hole on the disc feed side to be larger than the gap between the third guide pin and the third guide hole and the guide pin and the guide hole on the disc feed side. As a result, when the disk entry side and the entry side of the caliper body try to deform due to uneven stress due to braking torque, The deformation of the caliper supporting arm of disk rotation entrance side and a gap absorption of the slide pin and the guide hole,
The caliper body can be smoothly slid, and the caliper body can be improved in durability. Further, the third slide pin offset from the disc radial direction line to the disc feeding side effectively supports the braking torque from the caliper support arm together with the disc feeding side slide pin.

Further, in both inventions, when full braking at a high speed or when an excessive braking force is applied, the third slide pin offset to the disc feeding side, which exerts a large braking torque, causes the caliper body to have a high rigidity. Since it is supported, tilting of the caliper body is suppressed as much as possible. In addition, this effect can be achieved by using the conventional 2
This can be achieved by simply adding the minimum required one to the third slide pin as the third slide pin.
Compared to the conventional product that uses a large number of slide pins,
The workability, assembling efficiency, and economy are excellent, and since the disc brake is lightweight, the unsprung weight of the vehicle body can be reduced.

Further, by mounting elastic bushes for filling the gaps between the slide holes on the disc feeding side of the first invention and the slide pins on the disc feeding side of the second invention with the respective guide holes, during running or No more rattling of the slide pin and no contact noise at the beginning of braking.
