Abstract
The utility model discloses a double-piston brake cylinder assembly with guide rods. 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 side edge of each of the pistons. A counter bored hole is reserved in the rear end of each of the two pistons. A spring is clamped in each counter bored hole. A guide rod is sleeved in each spring. A protecting cover is arranged on an opening at each of the left and right ends of the oil chamber of the cylinder body. A shield is arranged between each protecting cover and the cylinder body. A vent screw is arranged at the top of the cylinder body. A vent screw cap is arranged at the top of the vent screw. A liquid inlet is also formed in the top of the cylinder body. A dustproof plug is arranged outside the liquid inlet. According to the double-piston brake cylinder assembly, the shields are arranged on the openings at the two ends of the cylinder body, a through hole, through which a corresponding piston rod penetrates, is reserved in the center of each shield, and the leather rings are arranged at the rear ends of the pistons, so that dust and oil 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 guide rod.
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 guide rod, 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 guide rod comprises 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; The two-piston side all is installed with apron; The two-piston rear end all has counterbore, is installed with spring in the counterbore, is set with guide rod in the spring; Cylinder body grease chamber right ends oral area is equipped with protecting cover, between protecting cover and the cylinder body guard shield is installed; 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, and liquor inlet is equipped with dust plug outward.
Said guard shield one end leans protecting cover, 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 is opened the hole and is supplied piston rod to pass through at the cylinder body end oral area guard shield being installed at the passport center, and in the structure that piston rear end is installed leather cup, 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 guide rod, 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; Two-piston 4 sides all are installed with apron 5; Two-piston 4 rear ends all have counterbore, are installed with spring 2 in the counterbore, are set with guide rod 3 in the spring 2; Cylinder body 1 grease chamber's right ends oral area is equipped with protecting cover 7, between protecting cover 7 and the cylinder body 1 guard shield 6 is installed; 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; Liquor inlet is equipped with dust plug 10 outward; Guard shield 6 one ends lean protecting cover 7, 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.
