Abstract
The utility model discloses an oil discharge device of a brake wheel cylinder, and the oil discharge device includes a cylinder body, wherein a radial through hole is arranged inside the cylinder body; a left piston and a right piston are arranged in the radial through hole; the left and right pistons are matched with the radial through hole in a sliding manner; a spring is connected between the inner side surfaces of the left and right pistons; an oil nipple leading to the radial through hole is arranged on the cylinder body; an oil discharge port is arranged at the bottom of the cylinder body; a stepped hole is arranged in the oil discharge port; a steel ball is placed in the stepped hole; and a spring is arranged between the bottom of the steel ball and the stepped surface of the stepped hole. The oil discharge device has a simple structure, and the bottom of the cylinder body is provided with the oil discharge port for discharging residue oil in the inner cavity of the cylinder body without causing pressure changes in the inner cavity of the cylinder body, so that influences on working efficiency of the pistons can be avoided.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of discharge equipment 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.
With oil as the wheel cylinder in braking source in long-term using process, can gather the oil of remnants in its inner chamber, influence the pressure of inner chamber, thereby influence the working efficiency of piston.
The model utility content
The purpose of the utility model provides a kind of discharge equipment of wheel cylinder, in the bottom of cylinder body oil drain out is set, and discharges remaining oil, avoids influencing the working efficiency of piston.
The technological scheme of the utility model is following:
A kind of discharge equipment 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 is connected with spring between the inner side surface of left and right piston; Described cylinder body is provided with the oil nozzle that leads to radial direction through hole, and the bottom of cylinder body is provided with oil drain out, is provided with step hole in the described oil drain out, is placed with steel ball in the step hole, is provided with spring between the bottom of said steel ball and the step surface of step hole.
The discharge equipment of described wheel cylinder is characterized in that: be positioned on the cylinder body at said radial direction through hole two ends and be separately installed with dust-proof cover, the middle part of said dust-proof cover is provided with through hole.
The discharge equipment of described wheel cylinder is characterized in that: the inner side surface of said left and right piston is provided with leather cup.
The beneficial effect of the utility model:
The utility model is simple in structure, in the bottom of cylinder body oil drain out is set, and discharges the bottom oil in the inner chamber of cylinder block, can not cause the variation of inner chamber of cylinder block pressure, thereby avoid influencing the working efficiency of piston.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of discharge equipment of wheel cylinder includes cylinder body 1; Be provided with radial direction through hole 10 in the cylinder body 1; Be provided with left and right piston 8,11 in the radial direction through hole 10, the hole wall of left and right piston 8,11 and radial direction through hole 10 is slidingly matched, and is connected with spring 2 between the inner side surface of left and right piston 8,11; Cylinder body 1 is provided with the oil nozzle that leads to radial direction through hole 10, and the bottom of cylinder body 1 is provided with oil drain out 3, is provided with step hole 6 in the oil drain out 3, is placed with steel ball 5 in the step hole 6, is provided with spring 4 between the step surface of the bottom of steel ball 5 and step hole 6.
Be positioned on the cylinder body 1 at radial direction through hole 10 two ends and be separately installed with dust-proof cover 7, the middle part of dust-proof cover 7 is provided with through hole; The inner side surface of left and right piston 8,11 is provided with leather cup 9.
When injecting in through hole 10 radially through oil nozzle when oily, under the effect of oil pressure, steel ball 5 extrusion springs 4; Thereby block the step hole 6 of oil drain out 3; After oil refluxed away, spring 4 restored and jack-up steel ball 5, and the bottom oil in the radial direction through hole 10 can flow away from the step hole 6 of oil drain out 3.
