Abstract
The utility model discloses a double-cylinder brake wheel cylinder of a light truck. The double-cylinder brake wheel cylinder comprises a cylinder. A working chamber is arranged in the cylinder, a left adjusting piston and a right adjusting piston are arranged in the working chamber, inlaying grooves are respectively arranged on side walls of the left and right adjusting pistons, leather rings are mounted in the inlaying grooves and are made of abrasion-resistant rubber, steel wire cords are arranged in the leather rings, inner lips and outer lips are arranged at ends of the leather rings, a circle of groove is arranged on an end surface of each piston, and oil return holes are arranged at bottoms of the grooves and are communicated with the inlaying grooves. The double-cylinder brake wheel cylinder has the advantages that a mounting component is reasonable in structure, and the double-cylinder brake wheel cylinder is stable in mounting and operation.
Description
Technical field
The utility model relates to a kind of light card two-cylinder type 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 (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, 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 and has 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, influence 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:
A kind of light card two-cylinder type wheel cylinder, comprise cylinder body, it is characterized in that: have active chamber in the described cylinder body, be provided with left and right two in the described active chamber and adjust piston, be respectively equipped with embedding groove on the sidewall of described left and right two adjustment pistons, in the described embedding groove apron is installed, described apron adopts abrasive rubber to make, described apron contains Steel cord, the end of described apron is provided with epipharynx and outer lip, described each piston end face is provided with a circle groove, and the bottom of described groove is provided with spill port and is communicated with embedding groove.
Described left and right two outer ends of adjusting piston are provided with the adjustment screw, are connected with dust-proof cover respectively on the sidewall of described adjustment piston and cylinder body.
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, is provided with spill port in the bottom of embedding groove, is being communicated with between spill port and the groove, play oil return and reduce the effect that 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.
Embodiment
Referring to accompanying drawing, a kind of light card two-cylinder type wheel cylinder, comprise cylinder body 1, has active chamber 2 in the described cylinder body 1, be provided with left and right two in the described active chamber 2 and adjust piston 3,4, be respectively equipped with embedding groove 6 on the sidewall of described left and right two adjustment pistons 3,4, in the described embedding groove 6 apron 7 is installed, described apron 7 adopts abrasive rubber to make, described apron 7 contains Steel cord, the end of described apron 7 is provided with epipharynx 8 and outer lip 9, and described each piston end face is provided with a circle groove 10, and the bottom of described groove 10 is provided with spill port 11 and is communicated with embedding groove 6.
Described left and right two outer ends of adjusting piston 3,4 are provided with push rod 12, are connected with dust-proof cover 5 respectively on the sidewall of described adjustment piston 3,4 and cylinder body 1.
Claims (2)
