Abstract
The utility model discloses an axle for an electric vehicle. The axle for the electric vehicle comprises a motor and an axle body. The motor is integrated on the axle body. One end of the motor is fixedly connected with the axle body through a connection disc, and the other end of the motor is connected with the axle through a fixing support. Compared with an original axle, the axle for the electric vehicle is simple in structure, does not need an original gearbox and the like for transmission, improves transmission efficiency, increases assembly rigidity, and reduces noise and vibration. In addition, the eccentric distance of the axle is increased, and the problems that the installation space of the motor is small and the motor easily interferes with other parts are solved.
Description
Technical field
The utility model belongs to the placement technique field of axle unit and vehicular propulsion, and a kind of electric vehicle vehicle bridge specifically is provided.
Background technology
Battery-driven car has the advantages such as energy-saving and environmental protection because of it, and is promoted gradually.But traditional three-wheeled electric vehicle, its chassis is generally all similar to fuel combustion vehicle, electrical motor, back axle, change speed gear box are separate, between them with mode transferring power such as chains, so complex structure, manufacturing cost is high, energy consumption is large, and when work each parts to send noise large, outside chain directly is exposed to, serious wear, difficult in maintenance.
Motor vehicle axle belongs to car load key structure spare, in use, itself can be subject to the effect of various reverse loads, easily causes the structural fatigue crackle, affects car load safety and in-use performance.Can carry out from atom, Micromechanics, macromechanics and Anti-Fatigue durability analysis angle the structural fatigue Study on cracks, comprise the material lattice defective, the material mechanism that crack damage occurs and develops under the alternate load effect, the researchs such as Anti-Fatigue durability analysis.
At present, the vehicle bridge of battery-driven car mostly is split type, and drive motor and vehicle bridge do not link together, motor be through transmission shaft with power transmission to vehicle bridge, driven by wheel and to travel.This is just so that complex structure is installed inconvenience; Simultaneously, the vehicle bridge of generally using has the shortcomings such as vibrations are large, noise is high, and driving efficiency is low, and motor mounting space is little.
The utility model content
Problem in view of above-mentioned prior art exists has proposed the utility model.
Therefore, the technical problems to be solved in the utility model is how to overcome the problem that motor vehicle axle shakes in the prior art, noise is large, driving efficiency is low, installing space is little.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of electric vehicle vehicle bridge, comprise motor and vehicle bridge body, described motor is integrated on the vehicle bridge body, described motor one end is fixedly connected by terminal pad and described vehicle bridge body, and its other end is connected with the vehicle bridge body by fixed support.
As a kind of preferred version of electric vehicle vehicle bridge described in the utility model, wherein: described vehicle bridge body two ends are provided with drg.
As a kind of preferred version of electric vehicle vehicle bridge described in the utility model, wherein: the drg at described vehicle bridge body two ends is connected with the parking brake line respectively.
The utility model adopts the mode of integrated installation, motor is integrated on the vehicle bridge body, such changing of design traditional electrical motor, the separate structure of back axle, it is incorporated into one, compact conformation, simple, be convenient to maintaining and low cost of manufacture; Compare with original vehicle bridge, this is simple in structure, does not need the transmission such as original change speed gear box, has improved driving efficiency, increases assembly rigidity, reduces noise, reduces vibrations.In addition, this vehicle bridge has increased eccentric throw, has solved motor mounting space little, easily with the problem of other part interference.
Description of drawings
Fig. 1 is the schematic diagram of an embodiment electric vehicle of the utility model vehicle bridge.
Fig. 2 is the schematic diagram of another embodiment electric vehicle vehicle bridge of the utility model.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Shown in Fig. 1-2, among the figure, vehicle bridge body 1; Motor 2; Terminal pad 3; Parking brake line 4; Drg 5; Fixed support 6.
As shown in Figure 1, a kind of electric vehicle vehicle bridge, it has comprised motor 2 and vehicle bridge body 1, wherein, motor 2 is integrated on the vehicle bridge body 1, is specially: motor 2 one ends are fixedly connected by terminal pad 3 and vehicle bridge body 1, and the then other end of motor 2 is connected with vehicle bridge body 1 by fixed support 6.
In this embodiment, the two ends of vehicle bridge body 1 also respectively are mounted with drg 5.
As shown in Figure 2, Fig. 2 is the schematic diagram of another embodiment electric vehicle vehicle bridge of the utility model.In this embodiment, motor 2 is fixedly installed on the vehicle bridge body 1, on vehicle bridge body 1, the one end is fixedly connected by terminal pad 3 and vehicle bridge body 1 mode that main employing two ends are fixed with motor 2 integrated installations, and the other end then is connected with vehicle bridge body 1 by fixed support 6.Two ends at vehicle bridge body 1 also respectively are mounted with a drg 5, and described drg 5 is connected with parking brake line 4 respectively.
So, the utility model provides a kind of electric vehicle vehicle bridge of integrate motor transmission, and its driving efficiency is high, shakes little and noise is low, and motor 2 installing spaces are large.Motor 2 is directly installed on the vehicle bridge body 1, and an end adopts terminal pad 3 to be connected with vehicle bridge body 1, and the other end is connected with vehicle bridge body 1 with fixed support 6.It is incorporated into one, compact conformation, simple, be convenient to maintaining and low cost of manufacture; Compare with original vehicle bridge, this is simple in structure, does not need the transmission such as original change speed gear box, has improved driving efficiency, increases assembly rigidity, reduces noise, reduces vibrations.In addition, this vehicle bridge has increased eccentric throw, has solved motor mounting space little, easily with the problem of other part interference.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
