Embodiment Construction

[0022] Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 to Figure 7 An embodiment in which the present invention is implemented in a movable caliper type disc brake device for a vehicle is shown, and a disc brake device 100 of this embodiment includes: a disc rotor 10 (see figure 1 imaginary line), which is assembled to the axle hub (rotating body not shown) so as to be able to rotate integrally with the wheel (not shown); the support body (fixer) 20, which is assembled to the vehicle body (not shown); The movable jaw 30 is disposed across a part of the outer periphery of the disk rotor 10 and assembled with the support body 20 so as to be movable in the rotor axial direction; a single piston (pushing member) 40 is assembled to the movable caliper 30 ; inboard brake pad 50 ; and outboard brake pad 60 . In addition, the disc brake device 100 includes a pair of leaf springs (block support springs) 70 and 80 respectively as...

Abstract

A disc brake device includes flat springs assembled in a support body and holding the brake pad back plates. The flat springs have a C-shaped part provided with: a connection surface part comprising a pad-receiving surface part; an outer circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially outward direction; and an inner circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially inward direction. Each flat spring also has a tongue-shaped part that: extends towards the connection surface part from the tip region of the inner circumferential surface part in the rotor circumferential direction; elastically engages an inner circumferential wall of a recess at a tip region of the tongue-shaped part; and biases the pad-receiving surface part towards a base wall of the recess.

Description

technical field [0001] The present invention relates to a disc brake device, and more particularly to a disc brake device comprising: a disc rotor capable of rotating integrally with a wheel; a support body assembled to a vehicle body; a pair of brake pads arranged In order to clamp a part of the above-mentioned disc rotor so as to be assembled with respect to the above-mentioned support body so as to be able to move in the rotor axial direction and the rotor circumferential direction; A convex portion is formed on the rotor circumferential end of the back plate of each of the brake pads, and a concave portion is formed on the support body to accommodate the convex portion of the back plate so as to be movable in the rotor axial direction and the rotor circumferential direction. A leaf spring assembled on the support body to hold the back plate is sandwiched between the upper portion and the concave portion, and the rotor circumferential front end of the convex portion is set ...
