Abstract
The utility model discloses an improved structure of a disc brake device for an electric vehicle. The improved structure comprises a brake shoe and a brake disc, wherein the brake disc and the hub of the electric vehicle are arranged separately; the brake disc is fixedly connected with the hub through a bush. According to the designed improved structure of the disc brake device, the brake disc and the hub in the disc brake device are arranged separately, and the brake device is not involved in the detaching process of a wheel, thereby greatly improving the maintenance convenience of the wheel and effectively prolonging the service lives of the brake disc and the hub.
Description
Technical field
The utility model relates to battery-driven car disc brake device, is specially the structure-improved of battery-driven car disc brake device.
Background technology
Butterfly brake gear because of its be active in one's movements, dispel the heat good, needn't adjust braking gap, be convenient to the feature of maintenance, be widely applied in battery-driven car, can effectively promote the maneuvering performance of battery-driven car.But in existing battery-driven car, the brake disc of butterfly brake gear is integrated with wheel hub, such structure is arranged so that must will remove butterfly brake gear in the time that wheel is safeguarded simultaneously, and not only dismounting bothers and wastes time and energy, and brings very large trouble to the maintenance of wheel.Being wholely set of wheel hub and brake disc, has also had a strong impact on both service life simultaneously, once one of them damage will all be changed, causes very large waste.
Utility model content
For the problems referred to above, the utility model has designed a kind of structure-improved of battery-driven car disc brake device, brake disc in its butterfly brake gear and wheel hub split arrange, in the unloading process of wheel, can not relate to brake gear, greatly lifting car is taken turns the convenience of maintenance, and can effectively extend the service life of brake disc and wheel hub.
For achieving the above object, the utility model is by the following technical solutions:
A structure-improved for battery-driven car disc brake device, comprises brake shoe and brake disc, it is characterized in that: described brake disc and electric vehicle hub split arrange, and brake disc is fixed together by a lining and wheel hub.
Further, above-mentioned lining outside is provided with the mounting groove that connects boss and wheel hub center and is connected.
Further, above-mentioned wheel hub passes through several bolts and is connected boss face connection.
Further, above-mentioned brake disc is connected with the inner end surface of lining by several bolts.
Brake disc of the present utility model and wheel hub adopt Split type structure, the lining significant interval that both arrange by centre is also fixed together, only need be by the releasing that is connected between wheel hub and lining in the unloading process of wheel hub, can not relate to the dismounting of brake disc, greatly the comfort feature of lifting car wheel maintenance.
In addition, the Split type structure setting of above brake disc and wheel hub, can just not damage and all change because of one of them, can effectively extend both service life, and reduce to a certain extent unnecessary waste.
Brief description of the drawings
Fig. 1, planar structure cutaway view of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of structure-improved of battery-driven car disc brake device, comprises brake shoe 1 and brake disc 2, described brake disc 2 and electric vehicle hub 3 split settings, and brake disc 2 is fixed together with wheel hub 3 by a lining 4.
At this, lining 4 outsides are provided with connection boss 41 and are connected with the mounting groove 31 at wheel hub 3 centers, and this structure can effectively promote both connection contact surfaces and strengthen both Joint strenghts.Whole wheel hub 3 by several bolts 32 be connected boss 41 end faces and be fixed together.
Described brake disc 2 is connected with the inner end surface of lining 4 by several bolts 21.
Above brake disc 2 adopts Split type structure with wheel hub 3, lining 4 significant intervals that both arrange by centre are also fixed together, in the unloading process of wheel hub 3, only the bolt 32 between wheel hub 3 and lining 4 need be connected to releasing, can not relate to the dismounting of brake disc 2, greatly the comfort feature of lifting car wheel maintenance.
In addition, the Split type structure setting of above brake disc 2 and wheel hub 3, can just not damage and all change because of one of them, can effectively extend both service life, and reduce to a certain extent unnecessary waste.
The above, it is only preferred embodiments of the present utility model, not utility model is done to any pro forma restriction, every foundation know-why of the present utility model, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of technical solutions of the utility model.
