Abstract
The utility model discloses a brake cylinder assembly with a conical head on each of double pistons. The 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 the left and right sides of the oil chamber. A leather ring is sleeved outside each of the two pistons. A conical head is connected to the inner side of each of the two pistons. A spring is clamped between the two pistons. A shield is arranged on each of left and right opening parts of the oil chamber of the cylinder body. A vent hole is formed in the top of the cylinder body. A vent screw is arranged in the vent hole. A vent screw cap is arranged at the top of the vent screw. An oil inlet joint is arranged at the top of the cylinder body. A dustproof plug is arranged outside the oil inlet joint. Each conical head is a cone. According to the brake cylinder assembly, the conical heads are arranged between the two pistons, so that an impulsive force produced by the collision of the pistons can be buffered, piston bodies can be protected, and problems caused by the long-term use of a cylinder can be avoided.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to the wheel cylinder assembly that all has conical head on a kind of double-piston.
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 only is equipped with spring between its piston, use rear spring to lose efficacy for a long time, and direct collision easily causes damage between the two-piston.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content
The purpose of the utility model just provides the wheel cylinder assembly that all has conical head on a kind of double-piston; Solve double piston type housing structure in the past, spring only is installed between its piston, use rear spring to lose efficacy for a long time; Easily direct collision between the two-piston causes the problem of damage.
The technological scheme that the utility model adopts is:
The wheel cylinder assembly that all has conical head on a kind of double-piston; Comprise cylinder body: the cylinder body middle part has the grease chamber; The left and right sides all is equipped with piston in the grease chamber, and two-piston all is set with apron outward, and the two-piston inboard all is connected with conical head; Be installed with spring between the two-piston, cylinder body grease chamber right ends oral area is equipped with guard shield; The cylinder body top is provided with vent hole, and bleed screw is installed in the vent hole, and the bleed screw top is equipped with bleeder cap, and the cylinder body top also is provided with fuel inlet fitting, and fuel inlet fitting is equipped with dust plug outward.
Said conical head is a Rotary-table.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through being provided with the structure of conical head between two-piston, the impulse force when can damper piston crashing, and the protection piston only 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:
The wheel cylinder assembly that all has conical head on a kind of double-piston; Comprise cylinder body 1: cylinder body 1 middle part has the grease chamber; The left and right sides all is equipped with piston 4 in the grease chamber, all is set with apron 3 outside the two-piston 4, and two-piston 4 inboards all are connected with conical head 9; Be installed with spring 2 between the two-piston, cylinder body 1 grease chamber's right ends oral area is equipped with guard shield 5; Cylinder body 1 top is provided with vent hole, and bleed screw 7 is installed in the vent hole, and bleed screw 7 tops are equipped with bleeder cap 8, and cylinder body 1 top also is provided with fuel inlet fitting, and fuel inlet fitting is equipped with dust plug 6 outward, and conical head 9 is a Rotary-table.
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.
Claims (2)
