Abstract
The utility model discloses a wheel cylinder assembly, comprising a cylinder body, a cavity is provided in the cylinder body, the side wall of the cavity is communicated with an air bleed screw and an oil inlet screw, left and right two pistons are respectively slidably installed at the left and right ends of the cavity, the adjacent surfaces of the left and right two pistons are provided with left and right two circular bosses, a spring is in a clamped connection between the left and right two circular bosses, the side walls of the two pistons are provided with grooves, a leather ring is embedded in the groove, and the left and right two outer end surfaces of the two pistons are respectively provided with a recessed cavity. The wheel cylinder assembly is advantaged by reasonable structure and good sealing performance.
Description
Technical field
The utility model 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.In order to reduce braking moment and physical dimension, break is contained on the high speed shaft of equipment usually, 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.
The model utility content
The utility model 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.
The utility model technical solution problem provides following scheme:
A kind of wheel cylinder assembly; Comprise cylinder body, have cavity in the said cylinder body, be linked with bleed screw and oil-feed screw 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.
The effect of the utility model 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.
The advantage of the utility model 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.
