Problems solved by technology

[0005] In order to overcome the defect that the gap self-adjusting mechanism of the existing disc brake gap due to the wear and tear of the brake block is not accurate enough to easily cause the failure of the entire brake during use and affect the braking safety of driving, the present invention The technical problem that needs to be solved is: to provide a new structure disc brake clearance self-adjusting mechanism, which has a long service life and accurate clearance adjustment. It will not affect the sensitivity of the brake when it is matched with the brake, so that the service life of the brake disc can be improved. Can be effectively guaranteed, compact, and easy to repair and maintain

Embodiment Construction

[0020] 1 and 2, it can be seen that the disc brake mainly includes a cam lever seat assembly 1, a cam lever bracket 25, and an end cover assembly 5, wherein the end cover assembly 5 is connected with the cam lever bracket 25. An eccentric cam lever 3 is arranged between the cam lever seat assembly 1 and the cam lever bracket 25, an inner semicircular bearing 2 is arranged between the cam lever 3 and the cam lever seat assembly 1, and the cam lever 3 and the cam lever bracket 25 is provided with an outer semicircular bearing 4, and the outside of the cam lever 3 has a force arm 19, which impels the cam lever 3 to move towards the position between the cam lever seat assembly 1 and the cam lever bracket 25 after receiving the external pressing power. Internal deflection, due to its eccentric setting, the cam lever 3 will impel the cam lever bracket 25 to run towards the brake disc during the rotation.

[0021] As can be seen in FIG. 1 , the disc brake clearance self-adjusting mec...

Abstract

This invention has provided one kind of disc brake gap self-modulation machine structure. In this disc brake gap self-modulation organization, the said brake includes the cam lever, the release forks connected on the lever, adjusting sleeve with a gap inserted with the fork. In the adjustment sleeve is equipped with a cylinder shape unidirectional bearing which is connected tightly with the adjusting sleeve. In the bearing is fitted with an internal sleeve in which is fitted with a screw-tube screw-rod interlinking mechanism. Advantages: accurate gap adjustment and long service life.

Description

technical field [0001] The invention relates to a brake used in automobiles, in particular to a gap self-adjusting mechanism of disc brakes operated by air pressure or hydraulic pressure. Background technique [0002] The types of brakes currently applied to the wheels of passenger and truck mainly include: drum brakes and disc brakes. Disc brakes powered by air and hydraulic pressure have the advantages of compact structure, good heat dissipation, and smooth braking. When braking, the brake pads are pressed against the brake disc from both sides under the action of the brake system, and finally The rotating brake disc is locked to achieve the purpose of braking the car. Drum brakes have been gradually replaced by disc brakes because of their instability during use. [0003] During the braking process of the disc brake, its friction plate will wear out, resulting in a larger braking gap, which will directly affect the braking effect of the car. Therefore, it is necessary ...
