Abstract
The utility model discloses a piston for a unidirectional adjustment type brake cylinder. The piston comprises a tubular piston body. A clamping groove is formed at the front end of the piston body. A mounting hole is reserved in the rear end of the piston body. An adjusting seat is arranged in the mounting hole in a matching way. An adjusting bolt is screwed in the adjusting seat. A circular groove is reserved on the end part of the adjusting seat. A compressed gas is introduced from an inlet hole, and drives the piston to slide, and the elasticity of a spring locking piece can be adjusted through the adjusting bolt to control a driving force for driving the piston, so that a braking function is realized; and the piston has a rational structure design and a good braking effect, the weight of the piston is further reduced, and the overall operational performance of an automobile is improved.
Description
Technical field
The utility model relates to the automobile brake field, specifically belongs to the piston of unidirectional regulating type wheel cylinder.
Background technique
The piston of unidirectional regulating type wheel cylinder is made up of brake cylinder head, piston, piston rod, leather cup and release spring etc., through the effect of three-way valve, when making pressurized air get into master cylinder, promotes piston and plays braking action through a cover base apparatus.The structure of piston design of present unidirectional regulating type wheel cylinder is reasonable inadequately, and volume is heavy, and braking effect is poor.
The model utility content
The purpose of the utility model provides a kind of piston of unidirectional regulating type wheel cylinder, and reasonable in design can be through regulating the elastic force of bolt Regulation spring locking plate; Thereby control promotes the Driving force size of piston; Weight further alleviates, and good braking effect has improved the whole usability of automobile.
The technological scheme of the utility model is following:
The piston of unidirectional regulating type wheel cylinder includes the cock body of tubular, and the front end of cock body is provided with draw-in groove, and the rear end of said cock body has mounting hole, is combined with the adjustment seat in the mounting hole, has screwed togather the adjusting bolt in the adjustment seat, and the end of adjustment seat offers annular groove.
The front end of described cock body has guide sleeve.
The inlet hole of the utility model feeds pressurized gas, and promotes the piston slip, can be through regulating the elastic force of bolt Regulation spring locking plate; Thereby control promotes the Driving force size of piston; Thereby the realization braking function, reasonable in design, weight further alleviates; Good braking effect has improved the whole usability of automobile.
