Specific embodiment

The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality The limitation of type.

Below with reference to Fig. 1-Fig. 4 detailed descriptions according to the brake 10 of the utility model embodiment.

As shown in Figure 2, Figure 3 and Figure 4, included according to the brake of the utility model embodiment 10：Caliper 1, friction plate 2 With wheel cylinder 3, friction plate 2 is fixedly mounted on caliper 1, and wheel cylinder 3 is also mounted on caliper 1, between wheel cylinder 3 and friction plate 2 Position limiting structure is provided with, position limiting structure has the function of to limit the rotation of 3 relative friction piece 2 of wheel cylinder.

Optionally, as Figure 1-Figure 4, position limiting structure includes：The limit protrusion 4 and limiting slot of mutual cooperation, limit convex Rise 4 and limiting slot in one be arranged on friction plate 2, and another in limit protrusion 4 and limiting slot is arranged on wheel cylinder 3 On, that is to say, that when limit protrusion 4 is arranged on friction plate 2, then limiting slot is arranged on wheel cylinder 3, when limit protrusion 4 When being arranged on wheel cylinder 3, then limiting slot is arranged on friction plate 2.

As Figure 1-Figure 4, when implementing to brake, wheel cylinder 3 under the promotion of hydraulic coupling, shift to by band movable friction plate 2 Brake disc, when its pressure reaches certain value, caliper 1 shifts to brake disc direction, while in caliper 1 along traveller is oriented to Under drive, friction plate 2 can shift to brake disc, and compress braking with caliper 1 along the guide groove of 1 clamp spring fixed feet of caliper Disk, so as to fulfill braking.When implementing parking braking, wheel has rotating tendency to vehicle under gravity, and wheel cylinder 3 is with rubbing Frictional force is generated between pad 2, which makes wheel cylinder 3 have rotating tendency, when wheel cylinder 3 rotates, the limiting slot of wheel cylinder 3 One side edge, contacted with the positive stop lug boss 4 on the backboard 5 of friction plate 2, the positive stop lug boss 4 just limits wheel cylinder 3 as a result, Rotation.When loosening the brake, the piston of wheel cylinder 3 retracts under the action of returning seal ring, and at the same time, friction plate 2 exists It retracts simultaneously with caliper 1 under the rotary thrust of brake disc, makes to generate certain interval between friction plate 2 and brake disc, braking solution It removes.

In addition, a specific embodiment according to the present utility model, limit protrusion 4 are arranged on friction plate 2, limiting slot is set It puts on wheel cylinder 3, i.e., this specific embodiment provides a kind of friction plate 2 with 4 structure of positive stop lug boss and with limiting slot structure Wheel cylinder 3 is largely avoided in this way when implementing parking braking, parking braking failure caused by the rear shifting of wheel cylinder 3 Problem.

As a result, by setting caliper 1, friction plate 2 and wheel cylinder 3, the front and rear shock of friction plate 2 and wheel cylinder 3 can be limited Rotation retract, so as to improve parking braking stability, so can solve the problems, such as parking braking fail, moreover, should Brake 10 is simple in structure, easy to maintenance, can also save a large amount of technological transformation cost.

Further, as Figure 1-Figure 4, limit protrusion 4 is arranged on friction plate 2, moreover, the quantity of limit protrusion 4 Be set as multiple, limiting slot is arranged on wheel cylinder 3, moreover, the quantity of limiting slot is set as multiple, multiple limit protrusions 4 with it is more A limiting slot corresponds, it is understood that is that the quantity of limit protrusion 4 is identical with the quantity of limiting slot, also, each is limited Position protrusion 4 can all coordinate there are one limiting slot with it, and setting in this way can increase the cooperation quantity of limit protrusion 4 and limiting slot, It retracts so as to preferably limit the rotation of wheel cylinder 3, and then vehicle parking stability and reliable can be increased substantially Property.

Specifically, as depicted in figs. 1 and 2, multiple limit protrusions 4 are in the length direction of friction plate 2 (on i.e. shown in FIG. 1 Lower direction) on be spaced apart distribution, the structural stability of friction plate 2 can be improved in this way by setting, and thereby may be ensured that friction plate 2 has There is preferable working performance.Wherein, length direction refer to upper and lower in Fig. 1 to.

Optionally, as depicted in figs. 1 and 2, the line between multiple limit protrusions 4 is set as straight line or camber line, in this way Setting can make limit protrusion 4 preferably be connected with limiting slot, so as to which the rotation of wheel cylinder 3 is further prevented to retract, And then the problem of parking braking is failed can be substantially reduced.

Further, as Figure 1-Figure 4, friction plate 2 can include：Backboard 5 and bloop 6 are provided on backboard 5 more A limit protrusion 4, bloop 6 are mounted on backboard 5, and when carrying out parking braking, friction plate 2 is contacted with wheel cylinder 3, are set in this way Bloop 6 can reduce the noise that friction plate 2 is generated with wheel cylinder 3 in friction process, so as to prevent the production of noise pollution It is raw.

Specifically, as shown in Figure 1-Figure 3, limit protrusion 4 is set as three, and one of limit protrusion 4 passes through bloop 6 After extend certain length, other two limit protrusion 4 sets the backboard of other two limit protrusion 4 without bloop 6 is needed guiding through 5 part is not correspondingly arranged on bloop 6.Setting can be such that the limit protrusion 4 across bloop 6 is matched with limiting slot in this way Connection is closed, thereby may be ensured that each limit protrusion 4 can play the role of limiting the rotation rollback of wheel cylinder 3.

Optionally, as Figure 1-Figure 4, bloop 6 is adhesively fixed with backboard 5, and setting in this way can be bloop 6 and the back of the body Plate 5 preferably links together, and so as to prevent bloop 6 from coming off from backboard 5, and then can preferably eliminate friction plate 2 noises generated when rubbing with wheel cylinder 3.But the utility model is without being limited thereto, and the fixed form of bloop 6 and backboard 5 can also Selected as plays the fixed form of phase same-action with Nian Jie fixed form.

Further, the depth of limiting slot is more than the height of limit protrusion 4, and setting in this way can facilitate limiting slot and limiting Protrusion 4 is connected, so as to greatly promote the working efficiency of brake 10.

According to the vehicle of the utility model embodiment, the brake 10 including above-described embodiment, the setting installation of brake 10 On vehicle, setting in this way can prevent the rotation of wheel cylinder 3 from retracting, and can also promote the stability and reliability of parking braking.
