Abstract
The utility model discloses a double-oil-chamber brake wheel cylinder assembly, which comprises a cylinder body, wherein the cylinder body comprises an upper oil chamber and a lower oil chamber, a separation plate is arranged between the two oil chambers, pistons are respectively arranged at two ends of each oil chamber, the inner side of each piston is provided with a leather cup, the inner side of each leather cup is provided with a spring seat, springs are clamped between the spring seats, protection covers are arranged between the outer ends of the pistons and the cylinder body, an oil seal springs are sheathed outside the protection covers, the upper end of the middle part of the cylinder body is provided with an oil inlet joint, a dustproof plug is arranged in the oil inlet joint, an exhaust hole is arranged at the upper end of the right side of the cylinder body, an exhaust screw is arranged in the air outlet hole, an exhaust cap is arranged on the top end of the exhaust screw, and the two oil chambers are communicated through an oil passage. The double-oil-chamber brake wheel cylinder assembly has the advantages that the leather cups are enlarged and are arranged at the end parts of the pistons so that the pistons cannot be clamped in the cylinder body, the guide performance of the leather cups is ensured, and the occurrence of the oil leakage phenomenon of a wheel cylinder is prevented.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to a kind of pair of grease chamber's wheel cylinder assembly.
Background technique
Wheel cylinder is positioned at clutch, and bolt is installed on the base plate usually, and it is converted into the hydraulic coupling from brake master cylinder and promotes the thrust that brake slipper compresses brake drum; The branch that single cylinder and twin-tub are arranged, wheel cylinder usually cylinder iron or aluminum alloy process, also useful stainless steel is processed; Grease chamber's sealing wheel cylinder of wheel cylinder is in order to avoid brake fluid leaks, and wheel cylinder is worked under the condition of HTHP, and oil sealing is housed on the cylinder body; Oil seal spring makes closely contact between sealing lip and the piston rod; Help to prevent that air from getting into, the back of most of wheel cylinder assemblies has air relief cock, is used for the air of the system of emitting; Piston and cylinder body end oral area are equipped with flexible soft lid and soft cover usually, allow piston motion and do not allow impurity and moisture entering; The wheel cylinder of conventional construction only has a grease chamber, and grease chamber's internal piston and leather cup are split-type design, and leather cup is sleeved on the piston outer wall, and this kind structure brings piston stuck in wheel cylinder easily, leather cup steering capability difference and cause the technical problem of wheel cylinder leakage of oil.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content
The purpose of the utility model just provides a kind of pair of grease chamber's wheel cylinder assembly; The wheel cylinder that solves conventional construction only has a grease chamber; Its internal piston and leather cup are split-type design; Leather cup is sleeved on the piston outer wall, and this kind structure brings piston stuck in wheel cylinder easily, leather cup steering capability difference and cause the technical problem of wheel cylinder leakage of oil.
The technological scheme that the utility model adopts is:
A kind of pair of grease chamber's wheel cylinder assembly comprises cylinder body: cylinder body has two grease chambeies up and down, is provided with dividing plate between two grease chambeies; Two ends all are equipped with piston in each grease chamber; The piston installed inside has leather cup, and the leather cup installed inside has spring seat, is installed with spring between the spring seat; Between piston outer end and the cylinder body guard shield is installed, guard shield is set with oil seal spring outward; Upper end, cylinder body middle part is provided with fuel inlet fitting, and dust plug is installed in the fuel inlet fitting, and upper end, cylinder body right side has vent hole, and bleed screw is installed in the air outlet hole, and the bleed screw top is equipped with the venting cap.
Be communicated with through oil duct between said two grease chambeies.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is provided with two up and down grease chambeies, and leather cup is strengthened and is installed in pistons end, makes the piston can be not stuck in cylinder body, and has guaranteed the leather cup steering capability, prevents that the wheel cylinder oil leakage phenomenon from taking place.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation side view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of pair of grease chamber's wheel cylinder assembly comprises cylinder body 1: cylinder body 1 has two grease chambeies up and down, is provided with dividing plate between two grease chambeies; Two ends all are equipped with piston 5 in each grease chamber; Piston 5 installed inside have leather cup 4, and the leather cup installed inside has spring seat 3, are installed with spring 2 between the spring seat 3; Between piston 5 outer ends and the cylinder body 1 guard shield 7 is installed, the guard shield 7 outer oil seal springs 6 that are set with; Upper end, cylinder body 1 middle part is provided with fuel inlet fitting, and dust plug 8 is installed in the fuel inlet fitting, and upper end, cylinder body right side has vent hole, and bleed screw 9 is installed in the air outlet hole, and the bleed screw top is equipped with between venting cap 10, two grease chambeies and is communicated with through oil duct.
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.
