Abstract
The utility model discloses a right-front hydraulic brake wheel cylinder of an automobile. The right-front hydraulic brake wheel cylinder comprises a cylinder. A cavity is arranged in the cylinder, an opening is arranged at one end of the cavity, an oil nozzle is arranged at the other end of the cavity and is communicated with the external, a piston is slidably mounted in the cavity, an annular groove is arranged on a side wall of the piston, a leather ring is inlaid in the groove, a retainer ring is fixedly mounted at the right end of the piston, a plurality of gear-shaped bosses are arranged on the outer wall of the retainer ring, a bleeder screw is arranged on a side wall of the cavity, and a bleeder cap covers the upper end of the bleeder screw. The right-front hydraulic brake wheel cylinder has the advantages of reasonable structure and convenience in installation and utilization.
Description
Technical field
The utility model relates to the right front hydraulic braking wheel cylinder of a kind of automobile.
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 (as mine hoist, elevator etc.) then should be contained near on the equipment work lower velocity shaft partly.
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 this utility model is in order to remedy the deficiency of prior art, provide a kind of automobile right front hydraulic braking wheel cylinder, 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 instability that causes, 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:
The right front hydraulic braking wheel cylinder of a kind of automobile, comprise cylinder body, has cavity in the described cylinder body, it is characterized in that: described cavity one end is provided with opening, the other end is provided with oil nozzle, described oil nozzle is in communication with the outside, be slidingly fitted with piston in the described cavity, the sidewall of described piston is provided with annular groove, be inlaid with apron in the described groove, the right part of described piston is installed with back-up ring, and the outer wall of described back-up ring is provided with multiple tracks gear shape projection, the sidewall of described cavity is provided with bleed screw, and the venting cap is stamped in described bleed screw upper end.
The left part of described piston is provided with the connection groove, and the right-hand member of described cylinder body is provided with dust-proof cover.
Effect of the present utility model is to formulate the hydraulic coupling that master cylinder transmits, be converted into mechanical thrust by piston, simultaneously by on the sidewall of piston, being provided with apron, front end at apron is provided with back-up ring, be provided with a plurality of gear shape projectioies on the sidewall of back-up ring, play the effect that bilayer stops, sealing effect is better, so effective balance of mode of operation the pressure of piston, and good seal performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
