Abstract
The invention discloses a wheel cylinder assembly. The wheel cylinder assembly comprises a cylinder body; a cavity is formed in the cylinder body; the side wall of the cavity is communicated with a bleed screw and an oil inlet screw; left and right pistons are arranged at the left and right ends of the cavity in a sliding way; adjacent surfaces of the left and right pistons are provided with left and right circular bosses; springs are clamped between the left and right circular bosses; the side walls of the two pistons are provided with grooves; leather collars are embedded in the grooves; and the left and right outer end faces of the two pistons are provided with a cavity respectively. The wheel cylinder assembly has a reasonable structure and is good in sealing performance.
Description
Technical field
The present invention relates to a kind of wheel cylinder assembly.
Background technique
Break is to have to make moving element (or movable machinery) slow down, stop or keeping the device of functions such as halted state.Be the mechanical parts that make the movement parts in the machinery stop or slowing down.Be commonly called as brake, lock.Break mainly is made up of system frame, brake component and Effector etc.Some break also is equipped with the automatic regulating apparatus in brake component gap.Usually be contained on the high speed shaft of equipment in order to reduce a braking moment and structure cun break, but the main equipment higher to security requirement (like mine hoist, elevator etc.) then should be contained on the lower velocity shaft near the equipment work part.
Wheel cylinder is as a vitals on the break, and the structural behaviour of wheel cylinder directly has influence on the working efficiency of break, is prone to the bad oil leakage phenomenon that causes of sealability of wheel cylinder in the existing technology.
Summary of the invention
The present invention provides a kind of wheel cylinder, remedies the technical deficiency in the existing technology, and the sealability that has solved between piston and the wheel cylinder master cylinder sidewall is not enough, causes the problems such as phenomenon of leakage of oil.
Technical solution problem of the present invention provides following scheme:
A kind of wheel cylinder assembly; Comprise cylinder body, concrete cavity is linked with bleed screw and oil-feed screw in the said cylinder body on the sidewall of said cavity; The right ends of said cavity is slidingly fitted with left and right sides two-piston respectively; It is characterized in that: two round boss about the adjacent surface of said left and right sides two-piston is provided with, be connected with spring between two round boss about said, the sidewall of said two-piston is provided with groove; Be inlaid with apron in the said groove, have cavity about said two-piston on two exterior edge faces respectively.
The sidewall of the right ends of said cylinder body is provided with draw-in groove, is connected with dust-proof cover in the said draw-in groove, and the center of said dust-proof cover is provided with circular hole.
Effect of the present invention is with formulating the hydraulic coupling that master cylinder transmits; Be converted into mechanical thrust through piston, adjust the spring between piston and the two-piston simultaneously, constantly adjust the spacing between the two-piston; Effectively controlled and kept optimal spacing between the two-piston, and good seal performance.
Advantage of the present invention with, between the two-piston of the left and right sides, be connected with returning spring, can be about to two-piston certainly to shift the two ends of cylinder body onto, and be inlaid with apron on the sidewall of piston, guaranteed sealability.
