Abstract

The utility model discloses a gas exhausting and oil discharging assembly for a wheel braking cylinder. The gas exhausting and oil discharging assembly 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 and are in sliding fit with the wall of the radial through hole; a spring is connected between the inner lateral surface of the left piston and the inner lateral surface of the right piston; an air tap and an oil nozzle which are communicated with the radial through hole are arranged on the cylinder body; an exhaust port and an oil discharging port are respectively arranged in the cylinder body; an air bleed screw is screwed at the exhaust port; an air bleed cap is arranged at the end part of the air bleed screw; a stepped hole is formed in the oil discharging port; a steel ball is arranged 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 gas exhausting and oil discharging assembly disclosed by the utility model is simple in structure; the exhaust port and the oil discharging port are arranged in the cylinder body and are respectively used for exhausting residual gas or discharging residual oil in an inner cavity of the cylinder body; and the functions of exhausting gas and discharging oil are integrated and the change of the pressure of the inner cavity of the cylinder body can be avoided, and thereby the influence on the work efficiency of the pistons is avoided.

Description

The exhaust of wheel cylinder and oil extraction assembly
Technical field
The utility model relates to the automotive brake field, is specifically related to a kind of exhaust and oil extraction assembly 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 gas or oil as the wheel cylinder in braking source in long-term using process, can gather gas or 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 exhaust and oil extraction assembly of wheel cylinder, and relief opening and oil drain out are set on cylinder body, discharges remaining gas or oil, avoids influencing the working efficiency of piston.
The technological scheme of the utility model is following:
A kind of exhaust of wheel cylinder and oil extraction assembly; 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 valve and the oil nozzle that leads to radial direction through hole; Be respectively equipped with relief opening and oil drain out on the cylinder body; Described relief opening has screwed togather bleed screw, and the end of said bleed screw has the venting cap, is provided with step hole in the described oil drain out; Be placed with steel ball in the step hole, be provided with spring between the bottom of said steel ball and the step surface of step hole.
The exhaust of described wheel cylinder and oil extraction assembly 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 exhaust of described wheel cylinder and oil extraction assembly is characterized in that: the inner side surface of said left and right piston is respectively equipped with leather cup.
The beneficial effect of the utility model:
The utility model is simple in structure, and relief opening and oil drain out are set on cylinder body, discharges residual gas or oil in the inner chamber of cylinder block, integrates exhaust and oil extraction function, 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 exhaust of wheel cylinder and oil extraction assembly; Include cylinder body 1, be provided with radial direction through hole 14 in the cylinder body 1, be provided with left and right piston 8,10 in the radial direction through hole 14; The hole wall of left and right piston 8,10 and radial direction through hole 14 is slidingly matched, and is connected with spring 2 between the inner side surface of left and right piston 8,10; Cylinder body 1 is provided with valve and the oil nozzle that leads to radial direction through hole 14; Be respectively equipped with relief opening 11 and oil drain out 3 on the cylinder body 1; Relief opening 11 has screwed togather bleed screw 12, and the end of bleed screw 12 has venting cap 13, is provided with step hole 6 in the oil drain out 3; Be placed with steel ball 5 in the step hole 6, be 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 14 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 said left and right piston 8,10 is respectively equipped with leather cup 9.
When the residual gas in the needs discharge radial direction through hole 14, turn on bleed screw 12, residual gas is discharged through the aperture and the venting cap 13 of relief opening 11, bleed screw 12 successively.
In through hole 14 radially, inject oil through oil nozzle; Under the effect of oil pressure, steel ball 5 extrusion springs 4, thus block the step hole 6 of oil drain out 3; When the bottom oil in the needs discharge radial direction through hole 14; Promptly after oil refluxed, spring 4 restored and jack-up steel ball 5, and the bottom oil in the radial direction through hole 14 can flow away from the step hole 6 of oil drain out 3.
