Abstract
The utility model discloses a novel brake wheel cylinder which includes a sub-pump piston arranged in the wheel cylinder, a sub-pump spring and a sub-pump leather cup arranged between the sub-pump pistons; the sub-pump leather cup is arranged on the sub-pump piston to form an integrated design; by adopting the technic proposal provided by the utility model, the technical problem of oil leakage of the wheel cylinder caused by that the piston is blocked in the wheel cylinder and the leather cup has poor steering capability as the sub-pump piston and the sub-pump leather cup of the traditional structure are fission-typed design can be effectively solved. Compared with the prior art, the utility model changes the connecting mode between the piston and the sealing leather cup from the separation-mode to the integration-mode, furthermore, the utility model has the advantages of simpler and more feasible process, low cost, long service life, etc.
Description
Technical field
The utility model is applied to brake system of car, specifically, relates to a kind of novel wheel cylinder.
Background technique
At present, in brake system of car, adopt the wheel cylinder of hydraulic type usually, generally comprise in wheel cylinder, the wheel cylinder wheelcylinder piston is set, wheelcylinder cup is set between wheelcylinder piston, between wheelcylinder cup, be provided with the branch pump spring;
The wheelcylinder piston of conventional construction and wheelcylinder cup are split-type design, are not designed to one between the two, and only by the spring force effect between the wheelcylinder cup, motion is close together; The wheel cylinder of this structure is reasonable inadequately in design, because piston length is shorter, it is shorter to add the length that leads man-hour, the manufacturing level is had relatively high expectations, cause that easily the processing of piston cylindricity is defective, cause piston stuck in cylinder body, piston and leather cup are separate type simultaneously, the steering capability of leather cup is relatively poor, and it is poorly sealed and the phenomenon of leakage of oil takes place that wheel cylinder takes place easily.
The model utility content
Technical problem to be solved in the utility model is, in brake system of car, be split-type design by the wheelcylinder piston and the wheelcylinder cup of conventional construction, the piston that brings is stuck in wheel cylinder, leather cup steering capability difference and cause the technical problem of wheel cylinder leakage of oil, and a kind of novel wheel cylinder is provided.
Technological scheme provided by the utility model is, a kind of novel wheel cylinder, comprise the wheelcylinder piston that is arranged in the described wheel cylinder, be arranged on branch pump spring, wheelcylinder cup between the described wheelcylinder piston, described wheelcylinder cup is arranged on the described wheelcylinder piston, and the formula design that becomes one.
Described wheelcylinder piston is provided with groove near the end of dividing pump spring.
The central axis of described groove and the central axes of wheelcylinder piston.
Described wheelcylinder cup is installed in the described groove.
The cross section of one end of described wheelcylinder cup is circular, and it is two circular that the cross section of the other end is.
The end that described cross section is two annulus is installed in a side of described minute pump spring.
Adopt technological scheme provided by the utility model, can effectively solve in brake system of car, wheelcylinder piston and wheelcylinder cup by conventional construction are split-type design, and the piston that brings is stuck in wheel cylinder, leather cup steering capability difference and cause the technical problem of wheel cylinder leakage of oil; Compared with prior art, changed the Placement of piston and sealing cup, become integrated type, and had on the technology more characteristics such as simple possible, cost are low, long service life by original separated type.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of wheel cylinder in the prior art;
Fig. 2 is the structural representation of wheel cylinder in the utility model;
Wherein, 1 is wheel cylinder; 2 is wheelcylinder cup; 3 for dividing pump spring; 4 is wheelcylinder piston.
Embodiment
As shown in Figure 1, wheel cylinder of the prior art comprises in wheel cylinder 1, the wheel cylinder 1 wheelcylinder piston 4 is set, and wheelcylinder cup 2 is set between wheelcylinder piston 4, is provided with branch pump spring 3 between wheelcylinder cup 2; Wheelcylinder piston 4 is a split-type design with wheelcylinder cup 2, is not designed to one between the two, and only by the spring force effect between the wheelcylinder cup 2, motion is close together.
As shown in Figure 2, a kind of novel wheel cylinder provided by the utility model, comprise a kind of novel wheel cylinder, comprise the wheelcylinder piston 4 that is arranged in the described wheel cylinder 1, be arranged on branch pump spring 3, wheelcylinder cup 2 between the described wheelcylinder piston 4, described wheelcylinder cup 2 is arranged on the described wheelcylinder piston 4, and the formula design that becomes one; Described wheelcylinder piston 4 is provided with groove near the end of dividing pump spring 3; The central axes of the central axis of described groove and wheelcylinder piston 4; Described wheelcylinder cup 2 is installed in the described groove; The cross section of one end of described wheelcylinder cup 2 is circular, and it is two circular that the cross section of the other end is; The end that described cross section is two annulus is installed in a side of described minute pump spring 3;
A kind of novel wheel cylinder provided by the utility model, its improvement is on the basis of former wheel cylinder structure, does not change whole profile, only by the change of partial structurtes, has not only reduced the danger of leakage of oil, and simple possible more on the technology.With former wheelcylinder piston 4 length lengthening, on piston, process a ring shaped slot, and allow wheelcylinder cup 2 be sleeved in wheelcylinder piston 4 ring shaped slots, make 2 one-tenth of wheelcylinder piston 4 and wheelcylinder cups as a whole.
Technological scheme provided by the utility model on the basis with wheelcylinder piston 4 lengthenings, is linked to be a monolithic construction with wheelcylinder piston 4 and wheelcylinder cup 2.On described wheelcylinder piston 4, ring groove is set, then wheelcylinder cup 2 is designed to described groove adapt ring-like, and be installed in the described groove, when piston motion, because described wheelcylinder cup 2 is an one with wheelcylinder piston 4, so wheelcylinder cup 2 is with wheelcylinder piston 4 motions; Again because an end cross section of wheelcylinder cup 2 is a circular shape, the other end cross section is two circular shapes, so end of two circular shapes of described wheelcylinder cup 2, promptly play the fixedly effect of wheelcylinder cup 2, can play the effect of sealing wheel cylinder 1 again, and, effectively overcome the technical problem of steering capability difference at the volley.
