Abstract
The utility model discloses a kind of electric motor car brake disc, including the first disk body, the second disk body, in annular shape, it is connected first disk body with the second disk body by fixed column；First disk body is provided with some heat emission holes；Shaft hole is provided among second disk body.The utility model is simple in construction, and brake area is big, good heat dissipation effect, good braking effect.
Description
Technical field
It the utility model is related to electric car spare and accessory parts field, more particularly to a kind of electric motor car brake disc.
Background technology
In the prior art, electric motor car brake disc is the friction means of disk braking system, and existing disk braking system
It is positive brake formula, i.e., brake disc is inwardly vised outside brake disc and reaches braking effect, the diameter of the brake disc of this structure is too small,
Brake area is small, and braking effect is poor.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provide a kind of simple in construction, real
Electric motor car brake disc.
The utility model is realized in the following way：
A kind of electric motor car brake disc, it is characterised in that：Including the first disk body, the second disk body, first disk body is in annulus
Shape, it is connected with the second disk body by fixed column；First disk body is provided with some heat emission holes；Among second disk body
Provided with shaft hole.
Further, it is provided with mounting hole in the fixed column.
Further, first disk body is provided with some lightening holes.
Further, it is provided with bearing in the shaft hole.
Further, the medial surface of second disk body is provided with some reinforcements.
Further, second disk body is provided with fixing hole.
The beneficial effects of the utility model are：Simple in construction, brake area is big, good heat dissipation effect, good braking effect.
Brief description of the drawings
Fig. 1 the utility model structural front views；
Fig. 2 the utility model structure rearviews.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made further specifically
It is bright.It should be appreciated that embodiment of the present utility model is not limited to the following examples, what the utility model was done is any
Formal accommodation and/or change falls within scope of protection of the utility model.
Embodiment：
A kind of electric motor car brake disc, as shown in Figure 1 and Figure 2, including the first disk body 1, the second disk body 2, first disk body 1
In annular shape, it is connected with the second disk body 2 by fixed column 3；First disk body 1 is provided with some heat emission holes 11；It is described
Shaft hole 21 is provided among second disk body 2.
In the present embodiment, mounting hole 31, the installation for brake disc are provided with fixed column 3.
In the present embodiment, the first disk body 1 is provided with some lightening holes 12, saves material, reduces production cost.
In the present embodiment, bearing 4, the rotation for axletree are provided with shaft hole 21.
In the present embodiment, the medial surface of the second disk body 2 is provided with some reinforcements 22, strengthens the intensity of brake disc.
In the present embodiment, the second disk body 2 is provided with fixing hole 23, the fixation for brake disc.
During implementation, the second disk body 2 is fixed on Electricmotor car wheel, bearing 4 is connected with electric car axletree, facilitates electronic
The rotation of car axletree；And the brake(-holder) block on brake is connected with the first disk body 1, brake is located at the inner side of the first disk body 1,
By braking of the brake to the first disk body 1, the system of realization arrives effect.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
