Abstract
The invention discloses a piston stroke adjustment device of a brake wheel cylinder. The piston adjusting device comprises a cylinder body, wherein a radial through hole is arranged in the cylinder body, a left piston and a right piston are arranged in the radial through hole, the left piston and the right piston are slidably matched with the hole wall of the radial through hole; a spring is connected between the left piston and the right piston, a dustproof cover is respectively arranged on cylinder bodies at two sides of the radial through hole, and oil nozzles which are communicated to the radial through hole are arranged on the cylinder bodies; the outer side of the left piston and the right piston is provided with a screw hole and spirally provided with a bolt, and a joint is arranged at the end part of the bolt. The piston stroke adjustment device has a simple structure; the joint is spirally arranged on the outer side of the piston, the joint can be adjusted left and right as required, and therefore requirements of the joint which is connected with external braking parts with different sizes are ensured; and the piston stroke adjusting device has favorable practical value.
Description
Technical field
The present invention relates to the automotive brake field, be specifically related to a kind of piston stroke regulating device of wheel cylinder.
Background technique
Wheel cylinder generally relies on pressurized air or oil to get into master cylinder, and promotion piston etc. overlap base apparatus and play braking action, are parts of automotive brake, are used to produce the power that hinders vehicle movement or movement tendency, i.e. braking force.
The piston of wheel cylinder inside is when being connected with external brake component, because the size of external brake component has length that weak point is arranged, and the adjustment space of piston in wheel cylinder is less, the difficulty that has caused piston joint to be connected with external brake component.
Summary of the invention
The piston stroke regulating device that the purpose of this invention is to provide a kind of wheel cylinder, the bolting joint in the piston outside, joint can carry out left and right adjustment on demand.
Technological scheme of the present invention is following:
A kind of piston stroke regulating device of wheel cylinder; Include cylinder body, it is characterized in that: be provided with radial direction through hole in the said cylinder body, be provided with left and right piston in the described radial direction through hole; The hole wall of described left and right piston and radial direction through hole is slidingly matched; And be connected with spring between the left and right piston, be positioned on the cylinder body of said radial direction through hole both sides and be separately installed with dust-proof cover, described cylinder body is provided with oil nozzle or the valve that leads to radial direction through hole; The outside of described left piston or right piston is provided with screw and has screwed togather bolt, and the end of said bolt has joint; Comprise the spring locking plate, an end of said spring locking plate is fixed on the outer wall of cylinder body, and the other end of spring locking plate is pressed in the outside of left piston or right piston.
The piston stroke regulating device of described wheel cylinder is characterized in that: the inboard of said left and right piston is respectively equipped with leather cup.
Beneficial effect of the present invention:
Compact structure of the present invention, the bolting joint in the piston outside, joint can carry out left and right adjustment on demand, has guaranteed the needs when the external brake component with the different size size is connected, and has good use value.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Referring to Fig. 1, a kind of piston stroke regulating device of wheel cylinder includes cylinder body 1; Be provided with radial direction through hole 8 in the cylinder body 1; Be provided with left and right piston 7,5 in the radial direction through hole 8, the hole wall of left and right piston 7,5 and radial direction through hole 8 is slidingly matched, and left and right piston 7, is connected with spring 3 between 5; Be positioned on the cylinder body 1 of radial direction through hole 8 both sides and be separately installed with dust-proof cover 5, cylinder body 1 is provided with the oil nozzle that leads to radial direction through hole 8; The outside of right piston 5 is provided with screw and has screwed togather bolt 6, and the end of bolt 6 has joint, and when the external brake component with the different size size was connected, bolt 6 can be adjusted on demand, thus the needs when having guaranteed to be connected with external brake component.
Further, the inboard of left and right piston 7,5 is respectively equipped with leather cup 2.
