Abstract
The utility model discloses a wheel-brake cylinder with oil storage tanks. The wheel-brake cylinder comprises a cylinder body, 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 annular oil storage tanks are arranged on the side walls of the left piston and the right piston, the left piston and the right piston are in sliding fit with the wall of the radial through hole, the front ends of the left piston and the right piston extend out of two ends of the radial through hole respectively and are sealed, a spring is connected between the left piston and the right piston, and an oil nozzle leading to the radial through hole is arranged at the upper end of the cylinder body. The wheel-brake cylinder is compact in structure, light in weight, small in occupied space, fine in sealing performance and quite convenient to mount and maintain, and has an excellent practical value. Besides, friction of the whole wheel-brake cylinder can be effectively reduced by the oil storage tanks.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of oil storage tank wheel cylinder that has.
Background technique
Wheel cylinder generally relies on pressurized air or oil to enter 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 most more complicated of existing wheel cylinder structure, volume is big, and it is big to take up room, and has brought inconvenience to installation and maintenance; Its inner piston seal performance is bad in addition, has influenced working efficiency greatly.
The model utility content
The purpose of this utility model provides a kind of oil storage tank wheel cylinder that has, and simplified structure improves sealability, makes installation and maintenance all very convenient.
The technical solution of the utility model is as follows:
A kind of oil storage tank wheel cylinder that has, include cylinder body, it is characterized in that: be provided with radial direction through hole in the described cylinder body, be provided with left and right piston in the described radial direction through hole, have annular oil storage tank on the sidewall of left and right piston, the hole wall of described left and right piston and radial direction through hole is slidingly matched, and the front end of left and right piston stretches out from the two ends of radial direction through hole respectively and seals, and is connected with spring between the left and right piston; The upper end of described cylinder body is provided with the oil nozzle that leads to radial direction through hole.
The described oil storage tank wheel cylinder that has is characterized in that: be positioned on the cylinder body of described radial direction through hole both sides and be separately installed with dust-proof cover.
The described oil storage tank wheel cylinder that has is characterized in that: seal by apron respectively between the hole wall of described left and right piston and radial direction through hole.
The beneficial effects of the utility model:
The utility model compact structure, in light weight, it is little to take up room, good seal performance, installation and maintenance is all very convenient, has good use value, and oil storage tank can effectively be that whole device reduces frictional force simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of oil storage tank wheel cylinder that has, include cylinder body 1, be provided with radial direction through hole 6 in the cylinder body 1, be provided with left and right piston 7,4 in the radial direction through hole 6, have annular oil storage tank 7-1,4-1 on the sidewall of left and right piston, the hole wall of left and right piston 7,4 and radial direction through hole 6 is slidingly matched, the front end of left and right piston 7,4 stretches out from the two ends of radial direction through hole 6 respectively and seals, and is connected with spring 2 between the left and right piston 7,4; The upper end of cylinder body 1 is provided with the oil nozzle 8 that leads to radial direction through hole 6, and the end of oil nozzle 8 is provided with dust plug 9.
Be positioned on the cylinder body 1 of radial direction through hole 6 both sides and be separately installed with dust-proof cover 5; Seal by apron 3 respectively between the hole wall of left and right piston 7,4 and radial direction through hole 6.
