Abstract
The invention relates to an automobile part, and particularly relates to a plunger type double-rubber cap air-braking wheel cylinder assembly for an automobile brake device. The plunger type double-rubber cap air-braking wheel cylinder assembly is provided with an intermediate shell, the intermediate part of the intermediate shell is provided with an air inlet nozzle; the intermediate part of the inner wall of the intermediate shell is provided with an annular lug boss; both ends of the annular lug boss are provided with a left rubber cap and a right rubber cap; the outer side of each rubber cap is provided with a plunger sleeve which is in threaded connection with the intermediate shell; the plunger sleeve is internally provided with a plunger; the inner end of the plunger supports against the bottom of each rubber cap; the outer end of the plunger is provided with a threaded hole; and the threaded hole is internally provided with an adjusting bolt provided with a locking nut in a matching way. The plunger type double-rubber cap air-braking wheel cylinder assembly disclosed by the invention solves the problem that brake speed, brake force and the like of the existing brake device are influenced due to complex structure of an air-braking assembly, difficult brake resetting and easiness for the abrasion and looseness of parts and is mainly used for an automobile brake system.
Description
technical field [0001] The invention relates to auto parts, in particular to a plunger-type double-skin-cup air brake wheel cylinder assembly used in an auto brake device. Background technique [0002] Automobile braking device is one of the important parts of automobiles. It usually has two structural forms: pneumatic brake and hydraulic brake. In the existing pneumatic brake system, the pneumatic part mainly consists of air brake cylinder assembly, fixed bracket, camshaft And the supporting seat, adjuster and other parts, the disadvantages are: the structure is complex, the brake is not easy to return, it needs to be injected with lubricating oil frequently, the parts are easy to wear and loose, affect the braking speed and braking force, and it is not easy to Adjust the average clearance between the upper and lower brake shoes and the brake drum. Contents of the invention [0003] The purpose of the present invention is to solve the problems that the structure of the p...
