Problems solved by technology

During such braking, since the part of the brake pad where the frictional force acts and the part that presses the brake pad with the pressing member such as the piston and the caliper claw deviates by as much as the thickness of the brake pad, the posture of the brake pad is likely to change. not stable
When the posture of the brake pad becomes unstable, the brake pad vibrates and produces a noise called buzzing, and the inner lining is prone to uneven wear

Embodiment Construction

[0081] [the first example of embodiment]

[0082] use Figure 1 to Figure 12 A first example of the embodiment will be described. The stacked gasket 1 of this example includes a base gasket plate 2 and a cover body gasket plate 3, such as Figure 9 ~ Figure 12 As shown, is loaded on the brake pad 4. The brake pad 4 is constructed by attaching a fixed lining 6 in front of the pressure plate 5 . In a state where such a brake pad 4 is incorporated into a disc brake device, the laminated spacer 1 is disposed between the back surface of the pressure plate 5 constituting the brake pad 4 and the pressing member 7 that presses the back surface of the pressure plate 5 . part. In addition, the front surface of the inner liner 6 constituting the brake pad 4 faces the axial side surface of the rotor 31 .

[0083] In the state before the laminated spacer 1 is mounted on the brake pad 4 in this example, the base spacer plate 2 and the cover body spacer plate 3 are bonded to each other ...

Abstract

Base-side locking pieces (10a) and (10b) extending from the flat base-side substrate portion (9) of a base gasket plate (2) toward the base gasket plate (2) side in the laminating direction of cam plates and cover-side locking piece (21a) and (21b) extending from the flat cover-side substrate portion (20) of a cover gasket plate (3) in the same direction as the base-side locking pieces (10a) and (10b) coincide in the radial direction. In this state, the cover side locking pieces (21a) and (21b) are inserted into base side through holes (12) provided in the base side substrate portion (9), so the circumferential end portion of the cover side locking piece (21a) and (21b) can be opposite to the circumferential side edge, that is, the movement restricting surface (24), of the base-side through hole (12).

Description

technical field [0001] The present invention relates to a laminated shim for a disc brake disposed between a brake pad for a disc brake and a pressing member that presses the brake pad against a rotor. Background technique [0002] In a disc brake device, a pair of brake pads clamps the rotor strongly from both sides in the axial direction, and brakes by frictional force acting on the abutting portion between the inner liner constituting the brake pads and the two axial side surfaces of the rotor. During such braking, since the part of the brake pad where the frictional force acts and the part that presses the brake pad with the pressing member such as the piston and the caliper claw deviates by as much as the thickness of the brake pad, the posture of the brake pad is likely to change. Get unstable. When the posture of the brake pad becomes unstable, the brake pad will vibrate and produce a noise called buzzing, and the lining is prone to uneven wear. [0003] The axial d...
