Abstract
The utility model discloses a dual-piston brake wheel cylinder assembly with a spring. The dual-piston brake wheel cylinder assembly comprises a cylinder body, the middle part of the cylinder body is provided with an oil chamber, left and right sides of the oil chamber are respectively equipped with a piston, the rear end of each of the two pistons is provided with a packing leather, a spring is clamped between two packing leathers, and left and right ports of the oil chamber of the cylinder body are respectively equipped with a protective cover; the top of the cylinder body is equipped with an air bleeding screw, the top of the air bleeding screw is equipped with an air bleeding screw cap, and the top of the cylinder body is further provided with a liquid inlet; a sealing ring is clamped in the liquid inlet, a dustproof plug is arranged outside the liquid inlet, and a through hole through which a piston rod passes is arranged at the middle part of each protective cover. According to the utility model, the protective covers are arranged at the ports of the cylinder body, the through holes are arranged at the middle parts of the protective covers so that the piston rods can pass through the through holes and the packing leathers are installed at the rear ends of the pistons, and therefore dust and air from can be effectively prevented from entering the oil chamber and the wheel cylinder does not have a fault 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 with spring.
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, the gap between its piston and the cylinder body does not have protective measures, 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 with spring, solves double piston type housing structure in the past, and the gap between its piston and the cylinder body does not have protective measures, 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 spring; Comprise cylinder body: the cylinder body middle part has the grease chamber, and the left and right sides all is equipped with piston in the grease chamber, and the two-piston rear end all is equipped with leather cup; Be installed with spring between two leather cups, cylinder body grease chamber right ends oral area is equipped with guard shield; The cylinder body top is equipped with bleed screw, and the bleed screw top is equipped with bleeder cap, and the cylinder body top also is provided with liquor inlet, is installed with seal ring in the liquor inlet, and liquor inlet is equipped with dust plug outward.
Said guard shield middle part has through hole, passes for piston rod.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through just installing guard shield at the cylinder body end oral area; Opening the hole at the guard shield center supplies piston rod to pass; And, can prevent effectively that dust and air from getting into the grease chamber in the structure that piston rear end is installed leather cup, 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 spring; Comprise cylinder body 1: cylinder body 1 middle part has the grease chamber, and the left and right sides all is equipped with piston 4 in the grease chamber, and two-piston 4 rear ends all are equipped with leather cup 3; Be installed with spring 2 between two leather cups 3, cylinder body 1 grease chamber's right ends oral area is equipped with guard shield 5; Cylinder body 1 top is equipped with bleed screw 8, and bleed screw 8 tops are equipped with bleeder cap 9, and cylinder body 1 top also is provided with liquor inlet, is installed with seal ring 6 in the liquor inlet, and liquor inlet is equipped with dust plug 7 outward, and guard shield 5 middle parts have through hole, pass for piston rod.
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.
