Embodiment Construction

[0063] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0064] 1. Pressure arm assembly 10

[0065] As mentioned above, the pressure arm assembly 10 includes a pressure arm 11, a fulcrum cylinder 12, a small needle roller pair 13, a large needle roller pair 14, and a shift fork 15, such as figure 2 ;

[0066] Pressure arm 11 is a kind of booster lever, constitutes cam mechanism with fulcrum cylinder 12, as Figure 4 .

[0067] The fulcrum cylinder 12 is a cylinder cut off one piece longitudinally, and its function is to provide a fulcrum for rotation, such as Figure 5 .

[0068] The small needle roller pair 13 is a semicircular cylindrical needle roller pair whose function is to reduce the friction between the rotating pairs, such as figure 2 .

[0069] The large needle roller pair 14 is a semicircular cylindrical needle roller pair whose function is to reduce the friction between the rotating pairs, such as figure 2 .

[0070] Sh...

Abstract

The invention comprises a pressure arm unit, a rotation shaft unit, a return spring, a push pedal, an internal friction plate, a brake, an external friction plate, a support and a caliper body arranged in order from right to left. Because of using the rectangular section torsional spring function, in a specific environment the invention can realize a one-way transmission of the torque and also can realize an overload protection effectively. The reasonable design of the pressure arm unit can supply the stable brake moment.

Description

technical field [0001] The invention relates to a brake suitable for medium and heavy commercial vehicles, in particular to a floating caliper double-push rod pneumatic disc brake based on a rectangular torsion spring one-way clutch; the brake can significantly reduce braking noise and provide a larger The braking torque effectively expands the application range of disc brakes. Background technique [0002] Pneumatic disc brakes, as a type of disc brakes, began in the 1990s and can be widely used in M1 and M2 passenger cars and N1 and above trucks. Pneumatic disc brakes have fast heat dissipation, light weight, simple structure, and automatic adjustment of wear clearance; especially high temperature resistance, stable braking effect, can significantly reduce braking distance, and provide reliable driving safety guarantee for vehicles. At the same time, the air disc brake can reduce the braking noise and effectively solve the noise pollution caused by urban bus braking. As ...
