Abstract
The utility model discloses a double-piston brake wheel cylinder assembly, which comprises a cylinder body. The middle portion of the cylinder body is provided with an oil chamber, a protection cover is respectively installed at the left end and the right end of the cylinder body, a piston is respectively installed on the inner sides of the protection covers, the middle portions of the pistons are all sleeved in O-shaped rings, the rear ends of the pistons are all sleeved in leather collars, and springs are clamped between the pistons. An air outlet is arranged at the top of the cylinder body, an air discharging screw is installed in the air outlet, an air discharging cap is installed at the top of the air discharging screw, the side edge of the middle portion of cylinder body is provided with an oil inlet connector, a dust-proof plug is installed outside the oil inlet connector, and the centers of the protection covers are provided with through holes for push rods to penetrate through. By enabling the oil inlet connector to incline at a certain angle and installing the seal leather collars and the O-shaped rings outside the piston, the double-piston brake wheel cylinder assembly can effectively prevent dust and air from entering the oil chamber and ensure that the wheel cylinder can not have problems after being 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.
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 double-piston wheel cylinder assembly, 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 comprises cylinder body: the cylinder body middle part has the grease chamber, and the cylinder body right ends all is equipped with guard shield; The guard shield inboard is separately installed with piston; The piston middle part all is set with O shape circle, and piston rear end all is set with apron, is installed with spring between the piston; 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 cylinder body middle part side 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 be through will going into oily tilt of joint several angle, and sealing apron and O shape circle are installed outside piston, can prevent effectively that dust and air from getting into the grease chamber, guarantee that wheel cylinder use for a long time 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 comprises cylinder body 1: cylinder body 1 middle part has the grease chamber, and the cylinder body right ends all is equipped with guard shield 6; Guard shield 6 inboards are separately installed with piston 5; Piston 5 middle parts all are set with O shape circle 4, and piston 5 rear ends all are set with apron 3, are installed with spring 2 between the piston 5; 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 7, and cylinder body middle part side is provided with into oily joint, goes into oily joint dust plug 9 is installed outward, and guard shield 6 centers have through hole, supply 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.
