Abstract
The utility model discloses a single-action brake wheel cylinder, which comprises a cylinder body, wherein a cavity is formed in the cylinder body; the side wall of the cavity is communicated with an air bleed screw and double oil inlets; ports of the oil inlets are covered by covers respectively; the left end and the right end of the cavity are slidably provided with a left adjusting piston and a right adjusting piston respectively; one end of the adjusting piston is slidably arranged in the cavity, and the other end of the adjusting piston is provided with a limiting flange; the outer end face of the adjusting piston at the left end is fixedly provided with an adjusting screw; side walls of adjacent ends of the left adjusting piston and the right adjusting piston are provided with annular clamping grooves; leather rings are clamped in the annular clamping grooves and are closely attached to the side wall of the cavity; the outer wall of the cylinder body is fixedly provided with a locking sheet and is provided with a mounting disc; mounting holes are formed at four corners of the mounting disc; and the side wall of the cylinder body is provided with bolt mounting holes and positioning holes. The single-action brake wheel cylinder has a rational and simple structure and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of single-acting 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; 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 the low and two ends of the efficient of single inflow pipeline are provided with dust-proof cover; Cause leakage of oil, phenomenon gets stuck.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art, a kind of single-acting wheel cylinder assembly to be provided, having solved in the brake system of car; The gap of piston and wheel cylinder active chamber can not be adjusted; And piston is the bad control in position in the active chamber of wheel cylinder, influences working efficiency, and external stability assembly unreasonable structure; The installation that causes is unstable, simultaneously poor sealing and problem such as leakage of oil occurs between piston and the cylinder body.
The utility model technical solution problem provides following scheme:
A kind of single-acting wheel cylinder comprises cylinder body, has cavity in the said cylinder body; Be linked with bleed screw and two filler openings on the sidewall of said cavity, the oral area of said filler opening is stamped stifle respectively, two adjustment pistons about the right ends of said cavity is slidingly fitted with respectively; One end of said adjustment piston is slidingly mounted in the cavity, and the other end has spacing flange, is installed with adjusting screw on the exterior edge face of said left end adjustment piston; It is characterized in that: have annular slot on the sidewall of the abutting end of two adjustment pistons about said; Be connected with apron in the said annular slot, fit tightly between said apron and the cavity wall, be installed with locking plate on the outer wall of said cylinder body; The outer wall of said cylinder body is provided with mounting disc, and the Si Jiaochu of said mounting disc has mounting hole.
The sidewall of said cylinder body is provided with bolt mounting holes and spacing 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 is, on the sidewall of former cylinder body, has offered two inflow pipelines, has shortened the gap of oil cylinder when oil return greatly; Improved the working efficiency of oil cylinder, on the outer wall of cylinder body, be provided with mounting disc, four jiaos of said mounting disc are provided with mounting hole; Adjustable gaps in piston and the wheel cylinder active chamber is whole; The position of piston in the wheel cylinder active chamber controlled easily, the good airproof performance of while piston and wheel cylinder, and have characteristics such as cost is low, long service life.
