The utility model of Chinese patent application number 201521097844.9 discloses a powder metallurgy brake pad, the friction block and the steel back are fixedly connected, the brake pad has no angle adjustment and floating adjustment during braking, and the friction block cannot be adjusted by itself, which is easy There are cracks, defects, etc.; and due to the inconsistent radial velocity of the brake disc, the friction block has a large difference in thickness between the inner and outer rings, which is very prone to eccentric wear
The utility model patent of Chinese patent application number 201420492365.6 discloses a vehicle with parking base brake device for rail transit. The above-mentioned device uses positioning pins to position the disc body and transmit the braking torque, which has the disadvantages of cumbersome assembly and heavy weight, and The lack of ideal cooling effect also affects the braking performance

Embodiment 1

[0056] See figure 1 and figure 2 , This embodiment includes a brake caliper E, a unit brake cylinder A, a brake pad D and a brake disc F. The brake caliper E has a pair of levers E1. The lever has upper and lower cross arms E1-1 and a vertical hinge shaft E1-2 connected between the upper and lower cross arms. The vertical hinge shaft extends out of the two upper cross arms. The space is connected by the upper connecting plate E5, and the vertical hinge shaft extends out and is connected by the lower connecting plate between the two lower cross arms. One end of the two levers E1 is respectively provided with a brake disc holder E2, each of which is plugged with the brake disc D, and the other ends of the two levers E1 are connected to the unit brake cylinder. The hanger E3 is fixed on the upper connection plate E5, and the brake caliper is equipped with a brake hanger E4 corresponding to each brake pad holder E2. The brake caliper is connected to the frame Q through 3 liftin...

Abstract

A vehicle foundation braking device comprises a braking clamp, an unit braking cylinder, a brake pad and a brake disc, wherein the unit braking cylinder comprises a braking cylinder body, an intermediate body, a braking piston assembly, a braking adjusting mechanism and a yoke; the braking adjusting mechanism comprises an adjusting shaft, a guide nut assembly and an adjusting nut assembly; a parking cylinder comprises a parking cylinder body, a parking piston assembly and a parking control mechanism; the parking control mechanism comprises a wedge-shaped body and a thrust sleeve. The vehicle foundation braking device is reliable in braking performance, and particularly can automatically adjust a gap which is enlarged caused by the wear between the brake pad and the brake disc during the braking process; an adjusting resisting assembly can timely act to resist adjustment of the braking adjusting mechanism when the braking force reaches a certain degree, and thus the gap between the brake pad and the brake disc can be kept within the normal range all the time.

Description

technical field [0001] The invention relates to a vehicle foundation braking device. Background technique [0002] See figure 1 and Figure 29 , The rail vehicle foundation braking device includes a brake caliper, a unit brake cylinder, a brake disc and a brake pad. The unit brake cylinder and the brake pads are respectively installed at both ends of the brake caliper. The brake disc is installed on the wheel shaft and between the two brake pads on the same brake caliper. When braking, the unit brake cylinder Inflated and elongated, the brake pads and brake discs are attached and rubbed together through the principle of leverage, thereby producing a braking effect. The utility model with the Chinese application number 201420447307.1 discloses a connection structure between the brake caliper and the brake cylinder of the rail vehicle foundation brake device. The brake caliper is composed of a hanger, a lever and a brake pad holder. The brake caliper has a symmetrical arran...
