Abstract
The utility model discloses a double-piston brake cylinder assembly with shields. The double-piston brake cylinder assembly comprises a cylinder body. An oil chamber is formed on the middle part of the cylinder body. A piston is arranged on each of left and right sides in the oil chamber. A leather ring is clamped at the rear end of each of the two pistons. A spring is clamped between the two pistons. The shields are arranged on the upper and lower parts of joints between the oil chamber of the cylinder body and the pistons. A vent screw is arranged at the top of the cylinder body. A vent screw cap is arranged at the top end of the vent screw. A liquid inlet is also formed in the top of the cylinder body. A sealing ring is clamped in the liquid inlet. A dustproof plug is arranged outside the liquid inlet. According to the double-piston brake cylinder assembly with the shields, the shields are arranged at the joints of the cylinder body and the pistons, and the leather rings are arranged at the rear ends of the pistons, so that dust and air can be effectively prevented from entering the oil chamber, and a cylinder is ensured not to have any problem 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 guard shield.
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 the double-piston wheel cylinder assembly of band guard shield, 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 guard shield; 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 installed with apron; Be installed with spring between the two-piston, the connecting part all is equipped with guard shield up and down between cylinder body grease chamber and the piston; 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 one end is installed in the groove of piston face, and the other end has lug boss, with the depressed part matching and fixing of cylinder surface.
Compared with prior art, the beneficial effect of the utility model is:
The utility model passes through at cylinder body and piston combining part guard shield to be installed, and in the structure that piston rear end is installed apron, can prevent effectively that dust and air from getting into the grease chamber, has guaranteed that the 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 guard shield; Comprise cylinder body 1: cylinder body 1 middle part has the grease chamber; The left and right sides all is equipped with piston 5 in the grease chamber; Two-piston 5 rear ends all are installed with apron 2, are installed with spring 4 between the two-piston 5, and the connecting part all is equipped with guard shield 6 up and down between cylinder body 1 grease chamber and the piston 5; Cylinder body 1 top is equipped with bleed screw 3; Bleed screw 3 tops are equipped with bleeder cap 9, and cylinder body 1 top also is provided with liquor inlet, is installed with seal ring 7 in the liquor inlet; Liquor inlet is equipped with dust plug 8 outward; Guard shield 6 one ends are installed in the groove on piston 5 surfaces, and the other end has lug boss, with cylinder body 1 depression in the surface portion matching and fixing.
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.
