Abstract
The utility model discloses a wheel braking cylinder assembly for a brake. The wheel braking cylinder assembly comprises a cylinder body, wherein a cavity is formed in the cylinder body; the middle part of the cavity is provided with a clapboard; the clapboard is used for partitioning the cavity into a left chamber and a right chamber; an adjusting piston is arranged in the left chamber in a sliding way; the side wall of the adjusting piston is provided with multiple annular oil storing grooves; an adjusting screw is arranged on the adjusting piston; a piston is arranged in the right chamber in a sliding way; a leather bowl is arranged on the end part of the piston; an anti-deformation iron wire is embedded into the leather bowl; a spring base is arranged on the end part of the leather bowl; a spring is fixedly arranged at the front end of the spring base; and the spring is pressed between the spring base and the clapboard. The wheel braking cylinder assembly is reasonable in structure, and is convenient to install and use.
Description
Technical field
The utility model relates to a kind of break 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 frame processed, 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 lower velocity shaft of equipment working portion.
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, a kind of break wheel cylinder assembly is provided, 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:
A kind of break wheel cylinder assembly, comprise cylinder body, has cavity in the described cylinder body, the middle part of described cavity has dividing plate, described dividing plate is divided into a left side with cavity, right two chambers, be slidingly fitted with the adjustment piston in the described left chamber, the sidewall of described adjustment piston is provided with multiple tracks annular oil storage tank,, on the described adjustment piston adjustment screw is installed, be slidingly fitted with piston in the described right chamber, the end of described piston is equipped with leather cup, is inlaid with the anti-deforming iron wire in the described leather cup, and the end of described leather cup is equipped with spring seat, described spring seat front end is installed with spring, and described spring is against between spring seat and the dividing plate.
Be connected with preceding dust-proof cover between described pistons end and the cylinder side wall.
Be connected with the back dust-proof cover between 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, adjust the spring between piston and the plug simultaneously, constantly adjust the spacing between the two-piston, effectively controlled and kept optimal spacing between the two-piston, and good seal performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of break wheel cylinder assembly, comprise cylinder body 1, has cavity 2 in the described cylinder body 1, the middle part of described cavity has dividing plate 3, described dividing plate 3 is divided into a left side with cavity 2, right two chambers 4,5, be slidingly fitted with in the described left chamber 4 and adjust piston 6, the sidewall of described adjustment piston 6 is provided with multiple tracks annular oil storage tank 14, be equipped with on the described adjustment piston 6 and adjust screw 7, be slidingly fitted with piston 8 in the described right chamber 5, the end of described piston 8 is equipped with leather cup 9, is inlaid with anti-deforming iron wire 15 in the described leather cup 9, and the end of described leather cup 9 is equipped with spring seat 10, described spring seat 10 front ends are installed with spring 11, described spring 11 is against between spring seat 10 and the dividing plate 3, and dust-proof cover 12 before being connected with between described piston 8 ends and cylinder body 1 sidewall is connected with back dust-proof cover 13 between the sidewall of described adjustment piston 6 and cylinder body.
