Problems solved by technology

In other words, due to the unique triangular shape of the torque receiving part between the pistons, the thickness of the outer peripheral side of the support frame is very thick, so the arrangement pitch of the pistons is increased, and the support frame is enlarged and heavy.
[0005] In addition, if the wall thickness of the torque receiving portion between the pistons is reduced only to reduce the arrangement pitch of the pistons, there will be a new problem that the triangular front end side of the torque receiving portion is missing and cannot fully The length of the torque receiving part is ensured, and the posture of the brake pad is unstable during braking

Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the drawings.

[0023] Figure 1 to Figure 7 Example 1 of the present invention is shown. As the disc brake of the present embodiment 1, the support frame is fixed, and its overall structure is as follows: Figure 2 ~ Figure 4 shown. In these figures, reference numeral 1 is a holder main body, and the holder main body 1 comprises an inner side holder half body 2A arranged inside the disk swivel D (vehicle inside) and a half body 2A arranged outside the disk turn D (vehicle outside). The outer support frame half body 2B is butted and connected as a whole. More specifically, each holder half body 2A and 2B has protrusions 3A, 4A protruding in the axial direction of the disc rotor D at three positions on both sides and the center along the circumferential direction of the disc rotor D. , 5A and 3B, 4B, 5B, in the state where these opposite protrusions 3A and 3B, 4A and 4B, 5A and 5B are butt...

Abstract

A disk-type brake, which can furthest reduce the thickness of the torque receiving department between the pistons and do not sacrifice the length. The disk-type brake has a plurality of pairs of pistons (15, 16) on both sides of the disk swivel, a plurality of brake pads (22,23) are compressed on the disk swivel (D) through the advancing towards each pair of pistons (15, 16), meanwhile, the sides of a plurality of brake pads (22,23) are supported on the torque receiving part (31, 32, 33) of the stand case (1) to generate braking force. The configure of the plurality of brake pads (22,23) is: in the radial of the disk swivel (D), at the center of rotation (O) relative to the disk swivel (D) and one point (P) in the region of the opposite to the stand case (1), the center lines of all blocks intersect to reduce the forward angle of the triangle in the torque receiving part (33) of the middle as much as possible, to reduce the arrange columns of the pistons (15, 16).

Description

technical field [0001] The present invention relates to disc brakes for motor vehicle braking, and more particularly to disc brakes for two-wheeled motor vehicles. Background technique [0002] Disc brakes for two-wheeled motor vehicles have the following brakes. On the main body of the support frame that contains a plurality of pistons arranged at least on one side of the disc rotating body along its rotation direction, it is slidable to support the pistons corresponding to the pistons. There are many pairs of brake blocks on both sides of the disc rotation body. With the advancement of the pistons, each pair of brake blocks is crimped on the disc rotation body. side of the brake block, thereby generating braking force. In addition, the pistons are disposed opposite to each other on both sides of the disc rotor in the bracket-fixed type disc brake, and are disposed only on one side of the disc rotor in the bracket-floating type disc brake. [0003]...
