Abstract

PURPOSE:To improve the heat insulating performance and consequently effectively suppress the transfer of heat generated by braking by a structure wherein ceramic material is arranged between the back face of the back plate of a pad and a caliper body. CONSTITUTION:A heat insulating plate 19 made of ceramic material is arranged at the back face of the back plate 4 of the pad 2 and furthermore a shim plate 20 is also arranged at the back face of the plate 19 and fixed integrally with the plate 19 to the pad 2 by means of rivets 21. Accordingly, the frictional heat, which is produced by the friction between a disc 1 and linings 3 and transmitted through the back plates 4 of the pads 2 via a piston 14 or a reaction part composing of an urging means to the liquid within a cylinder 13, is softened in transmission due to the insulating performance of the ceramic material, resulting in not bringing said liquid within the cylinder 13 up to high temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention improves the heat insulation effect by interposing a heat insulating material made of a ceramic material between the back surface of the pad back plate of a disc brake and the middle brake body to improve the heat insulation effect and improve the performance of the disc brake.

During disc play, the braking heat generated by the braking operation is transferred to various hand filters, but this heat is transferred to the back of the pad back plate XI*Yarino 5 body.
Conventionally, various efforts have been made to prevent this from occurring by increasing the temperature of the liquid in the cylinder operated by a suppressor provided in the caliper body.

The present invention has been developed based on various researches on this point, and has finally arrived at the insulation performance of Ceraden Ivy #O, and by interposing Ceraden Ivy material between the back of the pad back plate and the caliper body, the insulation performance of the tube is improved. I would like to provide you with a disc playback.

The illustrated embodiment will be described below.Firstly, an embodiment illustrated in 1llWA will be explained.A pair of pads m*2us, a pair of pads m*2us, respectively, are sandwiched between a disk 11 which is integrated with an axle shaft (not shown) and a pad back plate 4. consists of a bridge iig operating system)
i and summer crop #llll11 are placed across disk 1. Now, hanger bin 9 (usually two are used) in the Yaripapodi field. Hold pad back plate 4. support so as to be slidable in the direction. 1G is a pad spring ◎ This caliper body 8 is installed in a part of the vehicle body and is supported by slide bins 12 (usually two are used) K so as to be able to slide in the axial direction of the axle with respect to nine frames IIK. Then, the piston 14 located in the cylinder 13 formed in the first actuator 116 moves forward with hydraulic pressure from the braking operation, and pushes the actuating pad 3 that comes into contact with the tip of the piston 14, and the lining of the piston 14 is moved forward. 3 Pressly contact one side of the disk l,
The reaction causes the middle Yaripa body 8 to slide on the slide bin 18 in the direction opposite to the forward direction of the piston 14, and the pad 2 on the side of the summer operation 117 is pushed in the summer operation section 7. It presses against the other surface and performs braking by squeezing the disc L [lining is RK]. I
M is a lip seal, l@ is a corner seal, and 11111 is a boot.◎A heat insulating plate 19 made of a different electric ivy material is placed on the back of the back plate 4 of the pad 8, and a shim plate 20 is further provided on the back. , integrally attached to pad 2 with rivet 81
jlW&〇 Therefore, the piston 14 which is the pressing means through the pad back plate 4 or the summer operation '117) * in the cylinder 13
The frictional heat due to the braking between the disc l and the lining 3 is transmitted while being extremely relaxed due to the heat insulating properties of the ivy material, so it does not increase the height of the housing.

The embodiment shown below is composed of a piston 141 and a set write key 1, and the embodiment shown next is one in which the tip surface 14 of the piston 14 is in contact with the pad back plate 4.
The present invention is made of Cera electric ivy material, and can produce the same effect as the embodiment shown in Figure 1. As described above, the present invention Since it is made of one of the members or the -ay set electric ivy material, the heat insulating effect is improved and the heat transfer pipe generated during braking can be effectively suppressed.
