Abstract
The utility model discloses an automobile wheel cylinder, comprising a cylinder body, wherein the cylinder body is internally provided with a cavity; the side wall of the cavity is communicated with an air discharging screw and an oil inlet; an air discharging cap is arranged at the top of the air discharging screw; left and right pistons are respectively slidingly mounted at the left and right ends of the cavity; left and right packing cups are arranged on an adjacent face of the left and right pistons; the packing cups are respectively fixedly arranged on the side walls of the left and right pistons; the packing cups are tightly adhered to the side wall of the cavity and spring seats are fixedly mounted on the end faces of the left and right packing cups; and a spring is clamped between the two spring seats. The automobile wheel cylinder has the advantages of simple and reasonable structure, effective sealing and dust prevention.
Description
Technical field
The utility model relates to a kind of automobile wheel cylinder.
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, and the sealability that is prone to wheel cylinder in the existing technology is bad, and two ends are provided with dust-proof cover, causes leakage of oil, and phenomenon gets stuck.
The model utility content
The utility model provides a kind of wheel cylinder, remedies the technical deficiency in the existing technology, and the sealability and the anti-dust performance that have solved between piston and the wheel cylinder master cylinder sidewall are good inadequately, cause leakage of oil and stuck problems such as phenomenon.
The utility model technical solution problem provides following scheme:
A kind of automobile wheel cylinder comprises cylinder body, has cavity in the said cylinder body; Be linked with bleed screw and filler opening on the sidewall of said cavity; The top of said bleed screw is provided with the venting cap, and the right ends of said cavity is slidingly fitted with left and right sides two-piston respectively, it is characterized in that: two leather cups about the adjacent surface of said left and right sides two-piston is provided with; Said leather cup is fixedly mounted on respectively on the two-piston sidewall of the left and right sides; The sidewall of said leather cup and cavity fits tightly, and is installed with spring seat on the end face of two leather cups about said, is connected with spring between said two spring seats.
Have cavity on the exterior edge face of said left and right sides two-piston, the right ends of said cylinder body is covered with dust-proof cover.
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 installed with leather cup on the piston end face; Mounting spring seat in the leather cup; Effectively guaranteed the sealability between leather cup and the cavity inner wall, and dust-proof cover has been installed, guaranteed anti-dust performance in the right ends of cylinder body.
