The vehicle is equipped with a disc brake.
過去，於使用滑銷式之卡鉗本體之車輛用碟式煞車中存在有如下者：在卡鉗本體之作用部與反作用部之間隔著碟盤轉子對向配置一對之摩擦墊，於該摩擦墊之背板之碟盤外周側突設一對之懸掛部，並使該懸掛部橫跨作用部與反作用部地分別由被架設於碟盤軸向之一對之掛鉤銷所懸掛支撐(例如，參照專利文獻1)。然而，於專利文獻1之車輛用碟式煞車中，由於2根掛鉤銷被配置於卡鉗本體之內側，因此無法於摩擦墊及卡鉗本體安裝於車體之狀態下進行摩擦墊之更換，而在摩擦墊之更換上費時費力。 In the past, in a disc brake for a vehicle using a slide-type caliper body, there is a friction pad in which a pair of friction pads are disposed opposite to the disk rotor at an action portion and a reaction portion of the caliper body. a pair of hanging portions are protruded from the outer peripheral side of the disc of the back plate, and the hanging portion is suspended and supported by the hook pin which is mounted on one of the axial directions of the disk, respectively, across the action portion and the reaction portion (for example, Refer to Patent Document 1). However, in the disc brake of the vehicle of Patent Document 1, since the two hook pins are disposed inside the caliper body, the friction pad cannot be replaced while the friction pad and the caliper body are attached to the vehicle body. The replacement of the friction pad is time consuming and laborious.
因此，存在有使摩擦墊之懸掛片朝卡鉗本體之橋部的碟盤旋入側突出，並使上述懸掛片橫跨作用部與反作用部而由被架設於碟盤軸向之一根掛鉤銷所懸掛支撐之車輛用碟式煞車(例如，參照專利文獻2)。 Therefore, there is a case where the suspension piece of the friction pad protrudes toward the screw-in side of the bridge portion of the caliper body, and the suspension piece straddles the action portion and the reaction portion by one of the hook pins that are erected in the axial direction of the disk A disc brake for a vehicle that is suspended and supported (for example, refer to Patent Document 2).

專利文獻2：日本專利特開2004-132449號公報 Patent Document 2: Japanese Patent Laid-Open Publication No. 2004-132449
然而，於前述之專利文獻2之車輛用碟式煞車中，雖在摩擦墊及卡鉗本體安裝於卡鉗支架之狀態下，也可將掛鉤銷拆卸而更換摩擦墊，但由於使卡鉗本體之作用部與反作用部朝橋部之碟盤旋出側突出而架設掛鉤銷，因此使卡鉗本體大型化，且使得重量也增加。 However, in the disc brake of the vehicle of the above-mentioned Patent Document 2, the friction pin and the caliper body are attached to the caliper holder, and the hook pin can be detached to replace the friction pad, but the action portion of the caliper body is made. The reaction pin protrudes toward the screw-out side of the bridge portion to erect the hook pin, thereby increasing the size of the caliper body and increasing the weight.
因此，本發明之目的，在於提供一種車輛用碟式煞車，可一邊謀求卡鉗本體之小型化，一邊良好地更換摩擦墊。 Therefore, an object of the present invention is to provide a disc brake for a vehicle which can replace the friction pad satisfactorily while miniaturizing the caliper body.
為了達成上述目的，本發明之車輛用碟式煞車，藉由橋部連結被配置於碟盤轉子之一側部且具備有活塞之作用部與被配置於上述碟盤轉子之另一側部且具備有反力爪之反作用部而形成卡鉗本體，經由一對之滑銷將該卡鉗本體可朝碟盤軸向滑動地支撐於在上述碟盤轉子之一側部被固定設置於車體之卡鉗支架上，於上述作用部與反作用部之間，隔著上述碟盤轉子對向配置一對之摩擦墊，並使設置於該摩擦墊之懸掛部橫跨上述作用部與反作用部地由被架設於碟盤軸向之掛鉤銷所懸掛支撐，其特徵在於，上述摩擦墊於車輛前進時之碟盤旋入側且碟盤半徑方向外側形成上述墊懸掛部，並且於碟盤旋出側具備有抵接於設置在上述卡鉗本體或上述卡鉗支架之任一者的力矩承受部而傳遞制動力矩之力矩傳遞部，上述卡鉗本體於上述橋部之碟盤轉子側面，形成有使上述墊懸掛部可 朝碟盤軸向移動地加以收容之收容凹部。 In order to achieve the above object, a disc brake for a vehicle according to the present invention is disposed at a side portion of a disk rotor by a bridge portion, and includes an action portion of the piston and a side portion disposed on the other side of the disk rotor. The caliper body is formed by the reaction portion having the reaction claw, and the caliper body is slidably supported by the pair of sliding pins in the axial direction of the disk to the caliper fixed to the vehicle body at one side of the disk rotor a pair of friction pads are disposed between the action portion and the reaction portion via the disk rotor, and the suspension portion provided on the friction pad is erected across the action portion and the reaction portion. The suspension support is supported by the hook pin in the axial direction of the disk, wherein the friction pad is formed on the screw-in side of the disk when the vehicle is advanced, and the pad suspension portion is formed on the outer side in the radial direction of the disk, and is provided on the screw-out side of the disk. a torque transmitting portion that transmits a braking torque to a torque receiving portion of the caliper body or the caliper bracket, wherein the caliper body is formed on a side surface of the disk rotor of the bridge portion Pad suspension portion may A receiving recess that is accommodated in the axial direction of the disk.
又，較佳為上述摩擦墊於碟盤旋入側之外表面，具備有較上述卡鉗本體更突出於外側之抓取片。此外，較佳為上述摩擦墊藉由將上述掛鉤銷自上述卡鉗本體拆卸，並使上述摩擦墊之碟盤旋入側朝碟盤半徑方向內側轉動，而可在上述卡鉗本體安裝於上述卡鉗支架之狀態下自上述卡鉗本體拆卸。 Further, it is preferable that the friction pad is provided on the outer surface of the disk screw-in side, and the grasping piece that protrudes further outward than the caliper body is provided. Further, preferably, the friction pad is attached to the caliper holder by detaching the hook pin from the caliper body and rotating the disk of the friction pad to the inner side in the radial direction of the disk. Removed from the above caliper body in the state.
根據本發明之車輛用碟式煞車，由於摩擦墊使形成於碟盤旋入側且碟盤半徑方向外側之墊懸掛部，於卡鉗本體之內側被懸掛支撐於一根之掛鉤銷上，因此可一邊謀求卡鉗本體之小型化，一邊即便在卡鉗本體及摩擦墊安裝於卡鉗支架之狀態下，也可將掛鉤銷拆卸而更換摩擦墊。 According to the disc brake for a vehicle of the present invention, the pad suspension portion formed on the screw-in side of the disk and radially outward of the disk is suspended and supported by the hook pin on the inner side of the caliper body by the friction pad, so that one side can be suspended In order to reduce the size of the caliper body, the hook pin can be removed and the friction pad can be replaced even when the caliper body and the friction pad are attached to the caliper holder.
又，由於在摩擦墊之碟盤旋入側之外表面具備有較卡鉗本體突出於外側之抓取片，因此可抓住抓取片而良好地進行摩擦墊之更換作業。此外，由於摩擦墊藉由將掛鉤銷自卡鉗本體拆卸，並使摩擦墊之碟盤旋入側朝碟盤半徑方向內側轉動，而可在卡鉗本體安裝於卡鉗支架之狀態下自卡鉗本體拆卸，因此，配置有卡鉗支架之作用部側之摩擦墊也可容易地進行更換。 Further, since the outer surface of the friction pad is provided with a gripping piece that protrudes from the outer side of the caliper body, the grabbing piece can be grasped and the replacement of the friction pad can be performed satisfactorily. In addition, since the friction pad is detached from the caliper body by rotating the hook pin from the caliper body, and the disk of the friction pad is rotated to the inner side in the radial direction of the disk, the caliper body can be detached from the caliper body while being mounted on the caliper body. The friction pad on the side of the action portion on which the caliper bracket is disposed can also be easily replaced.
