Abstract
The utility model discloses a braking chief cylinder with an inclined air bleed screw on the top and a residual valve, which comprises a cylinder body, wherein the middle part of the cylinder is provided with an oil chamber, the left end of the oil chamber is provided with a piston assembly, the right end of the piston assembly is provided with a leather cup, the right end of the leather cup is provided with a spring seat, and the right end of the spring seat is provided with a return spring; and the right end of the cylinder body is provided with an oil outlet joint, the residual valve is arranged in the oil outlet joint, the left end of the residual valve is provided with a residual valve spring, and the return spring is propped at the left end of the oil outlet joint; the cylinder body on the upper end of the piston assembly is provided with an oil inlet joint; and the point of the upper end of the cylinder body, which is close to the oil outlet joint, is provided with the air bleed screw, a certain angle is formed between the air bleed screw and a horizontal plane, and the angle is 45-70 degrees. According to the utility model, the top of the cylinder body is provided with the air bleed screw with a certain inclined angle, so air can be prevented from flowing back to the cylinder body again in the air bleed process, the air bleed effect is ensured, and the overall service life of a product is prolonged.
Description
Technical field:
The utility model relates to the auto parts and components field, relates in particular to the brake master cylinder with residual valve that a kind of top has the inclination bleed screw.
Background technique:
Brake master cylinder band vacuum booster assembly is that power source as braking system exists basically, and it is that brake pedal force with the driver is converted into hydraulic coupling, and has certain power-assisted effect, is divided into the total accepted way of doing sth of single piston assembly and double-piston usually; Brake master cylinder structure in the past, its bleed screw mostly design at the cylinder body side, the direction level, the effect of giving vent to anger is bad, and has gas backstreaming in the deflation course and go in the cylinder body.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content:
The purpose of the utility model just provides the brake master cylinder with residual valve that a kind of top has the inclination bleed screw, solves brake master cylinder structure in the past, and its delivery connection is single delivery connection mostly; Can only be to a break output hydraulic coupling; In case piston assembly or valve go wrong, under the hypodynamic situation of hydraulic pressure, single break is with regard to akinesia; Cause automobile brake malfunctioning, breakneck technical problem.
The technological scheme that the utility model adopts is:
A kind of top has the brake master cylinder with residual valve of inclination bleed screw, comprises cylinder body: the cylinder body middle part has the grease chamber, and grease chamber's left end is equipped with circlip for hole; The circlip for hole right-hand member is equipped with thrust washer, and the thrust washer right-hand member is equipped with piston assembly, and the piston assembly left end is set with apron outward; The piston assembly right-hand member is equipped with leather cup; Be installed with the oil return sheet between leather cup and the cylinder body, the leather cup right-hand member is equipped with spring seat, and the spring seat right-hand member is equipped with return spring; The cylinder body right-hand member is equipped with delivery connection; Between delivery connection and the cylinder body copper washer is installed, the delivery connection right-hand member is equipped with dust plug, and residual valve is installed in the delivery connection; The residual valve left end is equipped with the residual valve spring; Residual valve spring left end is equipped with the valve thrust washer, and valve thrust washer left end is equipped with valve opening and uses circlip, and return spring leans at the delivery connection left end; The cylinder body of piston assembly upper end is provided with fuel inlet fitting, and fuel inlet fitting is equipped with dust cap outward; The cylinder body upper end is provided with bleed screw near the delivery connection place, and bleed screw is equipped with bleeder cap outward.
Said bleed screw is horizontal by certain angle, and angle is 45 °-70 °.
Compared with prior art, the beneficial effect of the utility model is:
The utility model can prevent effectively that through the bleed screw with certain angle of inclination is set at the cylinder body top gas passes back in the cylinder body again in the deflation course, has guaranteed the venting effect, has increased the product bulk life time.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of top has the brake master cylinder with residual valve of inclination bleed screw; Comprise cylinder body 1: cylinder body 1 middle part has the grease chamber, and grease chamber's left end is equipped with circlip for hole 4, and circlip for hole 4 right-hand members are equipped with thrust washer 2; Thrust washer 2 right-hand members are equipped with piston assembly 5; Piston assembly 5 left ends are set with apron 3 outward, and piston assembly 5 right-hand members are equipped with leather cup 8, are installed with oil return sheet 7 between leather cup 8 and the cylinder body 1; Leather cup 8 right-hand members are equipped with spring seat 9, and spring seat 9 right-hand members are equipped with return spring 10; Cylinder body 1 right-hand member is equipped with delivery connection 16; Between delivery connection 16 and the cylinder body 1 copper washer 15 is installed, delivery connection 16 right-hand members are equipped with dust plug 19, and residual valve 18 is installed in the delivery connection 16; Residual valve 18 left ends are equipped with residual valve spring 17; Residual valve spring 17 left ends are equipped with valve thrust washer 12, and valve thrust washer 12 left ends are equipped with valve opening with circlip 11, and return spring 10 leans at delivery connection 16 left ends; The cylinder body 1 of piston assembly 5 upper ends is provided with fuel inlet fitting, and fuel inlet fitting is equipped with dust cap 6 outward; Cylinder body 1 upper end is provided with bleed screw 13 near delivery connection 16 places, outside the bleed screw 13 bleeder cap 14 is installed, and bleed screw 13 is horizontal by certain angle, and angle is 45 °-70 °.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection domain of the utility model.
