Abstract
The utility model discloses a double-piston brake wheel cylinder assembly with large spring seats, comprising a cylinder body, wherein the middle of the cylinder body is provided with an oil chamber, shields are mounted at the left and the right ends of the cylinder body respectively, pistons are mounted on the inner sides of the shields respectively, leather cups are mounted on the inner sides of the pistons respectively, the large spring seats are respectively mounted on the inner sides of the leather cups, and a spring is clamped between the large spring seats; an air outlet is arranged on the top of the cylinder body, a deflation screw is mounted in the air outlet, a deflation cap is mounted on the top of the deflation screw, an oil inlet joint is also arranged on the top of the cylinder body, a dustproof plug is mounted outside the oil inlet joint, and a through hole is arranged in the center of each shield and is used for a push rod to pass through. According to the double-piston brake wheel cylinder assembly, the oil inlet joint is vertically arranged on the top of the cylinder body, sealing leather cups are mounted on the side edges of the pistons, so that dust and air are effectively prevented from entering the oil chamber, and the wheel cylinder is ensured to be normally used for a long time.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to a kind of double-piston wheel cylinder assembly with the big spring seat.
Background technique
Wheel cylinder is the important composition parts of brake device for car, is usually located in the break, is screwed on the base plate by bolt; It changes into the brake fluid pressure from brake master cylinder and promotes the thrust that brake slipper compresses brake drum, has plenty of twin-tub, and every has a piston; Have plenty of single cylinder, have only a piston, the other end sealing of wheel cylinder; Wheel cylinder is processed by cast iron, aluminum alloy or stainless steel usually, and grease chamber's sealing of wheel cylinder is in order to avoid brake fluid leaks; Double piston type housing structure in the past, it goes into oily joint is the design that is parallel to cylinder body, makes dust and air get into the grease chamber easily.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 wheel cylinder assembly with the big spring seat, solves double piston type housing structure in the past, and it goes into oily joint is the design that is parallel to cylinder body, makes dust and air get into the problem of grease chamber easily.
The technological scheme that the utility model adopts is:
A kind of double-piston wheel cylinder assembly with the big spring seat; Comprise cylinder body: the cylinder body middle part has the grease chamber; The cylinder body right ends all is equipped with guard shield, and the guard shield inboard is separately installed with piston, and the piston inboard is separately installed with leather cup; The leather cup inboard is separately installed with the big spring seat, is installed with spring between the big spring seat; The cylinder body top is provided with the air outlet, and bleed screw is installed in the air outlet, and the bleed screw top is equipped with the venting cap, and the cylinder body top also is provided with into oily joint, goes into oily joint dust plug is installed outward.
Said guard shield center has through hole, supplies push rod to pass.
Compared with prior art, the beneficial effect of the utility model is:
The utility model vertically is arranged on the cylinder body top through going into oily joint, and at the piston side sealing cup is installed, and can prevent effectively that dust and air from getting into the grease chamber, has guaranteed that long-time use of wheel cylinder can not go wrong yet.
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 double-piston wheel cylinder assembly with the big spring seat; Comprise cylinder body 1: cylinder body 1 middle part has the grease chamber; The cylinder body right ends all is equipped with guard shield 6, and guard shield 6 inboards are separately installed with piston 5, and piston 5 inboards are separately installed with leather cup 2; Leather cup 2 inboards are separately installed with big spring seat 3, are installed with spring 4 between the big spring seat 3; Cylinder body 1 top is provided with the air outlet, and bleed screw 8 is installed in the air outlet, and bleed screw 8 tops are equipped with venting cap 9, and cylinder body 1 top also is provided with into oily joint, goes into oily joint dust plug 7 is installed outward, and guard shield 6 centers have through hole, supplies push rod to pass.
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.
