Bracket-free floating air pressure caliper disc brake

Abstract

An unsupported, floating, and pneumatic caliper disc brake, comprising a mounting plate (1), a brake caliper assembly (2), two guide pins (3), screws (4), a friction plate (5), pressure springs (6), and a pressure plate (7); wherein a central through-hole is provided on the mounting plate (1), the central through-hole being used for centring on a non-steering axle, and the brake caliper assembly (2) is directly fixed onto the mounting plate (1) by means of the guide pins (3). The brake is simple in structure, convenient for assembling and convenient for maintenance. Given that a support has been removed, a saving is made on cost and in the setting up process. In addition, the brake ensures braking performance and eliminates the negative impact created when support is withdrawn.

Description

technical field [0001] The invention relates to the field of vehicle brakes, in particular to a bracketless floating air pressure caliper disc brake without brackets. Background technique [0002] In vehicle driving, brakes, as an important part, have always been the focus and difficulty of vehicle design. Among the existing brakes, compared with traditional drum brakes, air pressure caliper disc brakes have stable braking torque and resistance to thermal fading. , The ability of water fading is very excellent, and the air caliper disc brake can conveniently realize parking and automatic compensation of friction plate wear. At present, the application of air pressure caliper disc brakes on urban buses and trucks has been very extensive. But the factor that hinders air disc brake to popularize still exists, and wherein cost problem is still one of important factors that perplexes air caliper disc brake. [0003] Commonly used floating air caliper disc brakes are mainly comp...

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
