Bracket-free floating air pressure caliper disc brake

Abstract

The invention discloses a bracket-free floating air pressure caliper disc brake. The brake comprises a mounting plate (1), a brake caliper assembly (2), two guide pins (3), a screw (4), a friction plate (5), a pressure spring (6) and a pressure plate (7), wherein the mounting plate (1) is provided with a central through hole, the central through hole is centered on a non-steering axle, and the brake caliper assembly (2) is directly fixed on the mounting plate (1) through the guide pins (3). The brake has simple structure, is convenient to assemble and maintain, cancels a bracket, saves the cost and the assembly step, meanwhile, can ensure the braking performance, and eliminates the negative effect of canceling the bracket.

Description

Technical field [0001] The invention relates to the field of brakes of vehicles, in particular to a bracketless floating air pressure caliper disc brake without a bracket. Background technique [0002] In vehicle driving, brakes, as an important component, have always been the focus and difficulty of vehicle design. Among the existing brakes, air caliper disc brakes have stable braking torque and resistance to thermal degradation compared to traditional drum brakes. , The water decay ability is very excellent and other advantages, and the pneumatic caliper disc brake can easily realize parking and automatic compensation of friction lining wear. At present, the application of pneumatic caliper disc brakes on city buses and trucks has been very extensive. However, the factors that hinder the promotion of air disc brakes still exist, and the cost issue is still one of the important factors that plague air caliper disc brakes. [0003] The commonly used floating air caliper disc brak...

Problems solved by technology

[0005] The function of this bracket is also limited to fixing and connecting, but the brackets of traditional floating air caliper disc brakes need to be relatively large in size and weight, resulting in increased cost and complicated assembly. Therefore, in the development of brakes, proposed The design concept of canceling the bracket

[0006] In the European patent EP0906856A2, the patent combines the functions of the mounting plate and the bracket, but the shape of the new mounting plate borrows the structure of the original bracket, the shape is very complicated, the difficulty of processing, the overall cost and the weight of the assembly are not enough significantly improved

In addition, the rigidity of this open friction plate guide structure is not good, which reduces the torsion bearing capacity of the outer plate of the friction plate, and long-term use is prone to eccentric wear and abnormal braking noise
