Description
Technical field
The utility model relates to the suspension of pure electric automobile and the arrangement structure of support, is specifically related to a kind of front cabin structure of pure electric automobile.
Background technology
Compared with orthodox car, the dynamic assembly module of electronlmobil adds the modules such as such as electric machine controller, converter, DC-AC converter and charger, if above-mentioned newly-increased module arrangement is at the front of dynamic assembly or rear, the collision energy-absorbing space of vehicle greatly will be reduced; In addition, due to the motor of electronlmobil and retarder opposite engine and change-speed box small volume, its centroid position on the lower, dynamic assembly increases immediately to the distance of suspension attachment point, this just needs to increase mounting bracket length and connects dynamic assembly, be unfavorable for the spacing of suspension system and vibration isolation, and also can propose higher requirement to the intensity of supporting structure.And comparing to traditional driving engine, the change in torque of motor is fast, needs suspension to provide better anti-and turns round performance.
Utility model content
In view of this, the utility model provides a kind of front cabin structure of pure electric automobile, is intended to improve the vibration isolation of suspension, spacing and anti-twisting property, provides compact dynamic assembly layout and the collision energy-absorbing space of front deck.
The technical solution adopted in the utility model is specially: a kind of front cabin structure of pure electric automobile, comprises crossbeam, mounting assembly and motor-retarder, and described mounting assembly comprises left suspension, right suspension, the first anti-torsion suspension are put the anti-torsion suspension with second and put; Described subframe and described motor-retarder are fixed on the below of described crossbeam, the left longeron of vehicle body is fixed in described left suspension, the right vertical beam of vehicle body is fixed in described right suspension, and described first anti-torsion suspension is put and is fixed on subframe, and described second anti-torsion suspension is put and is fixed on described right vertical beam.
Before above-mentioned pure electric automobile in cabin structure, described right suspension is connected with described crossbeam by right suspension bracket, and described second anti-torsion suspension is put and is fixed on described right suspension bracket.
Before above-mentioned pure electric automobile in cabin structure, described left suspension is connected with described crossbeam respectively with described right suspension.
Before above-mentioned pure electric automobile in cabin structure, described crossbeam is also provided with the first attachment point and the second attachment point, the top of described crossbeam is fixed with electric machine controller and power module respectively by described first attachment point and described second attachment point.
Before above-mentioned pure electric automobile in cabin structure, described power module comprises converter, DC-AC converter and charger.
Before above-mentioned pure electric automobile in cabin structure, described motor-retarder is fixed on the below of described crossbeam by left mounting bracket and right mounting bracket.
The beneficial effect that the utility model produces is:
The suspension of continuity conventional gasoline car and Automobile longitudinal beam structure, then under the prerequisite reducing cost of development as far as possible, achieve hardware and software platform; Accessory module is installed on the top of crossbeam, has effectively isolated the ground vibration being delivered to accessory module, added the service life of accessory module;
Dynamic assembly and accessory module are designed to integrative-structure, improve the centroid position of dynamic assembly, make it closer to suspension attachment point, improve vibration isolation and the restraining ability of suspension; And on the trailing arm of right suspension, increase anti-torsion suspension put, not affecting under the prerequisite that other three-point suspensions arrange, improve the anti-ability of turning round of suspension;
Entire arrangement spaces compact, the energy-absorbing space touched before adding vehicle, reduces the length of mounting bracket (cantilever), and the reliability of suspension is promoted.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, more completely the utility model can be understood better.Accompanying drawing described herein is used to provide further understanding of the present utility model, and embodiment and explanation thereof, for explaining the utility model, do not form improper restriction of the present utility model, wherein:
Fig. 1 is the structural representation of the front cabin structure of a kind of pure electric automobile of the utility model.
In figure: 1, left suspension 2, left mounting bracket 3, right suspension 4, the anti-torsion suspension of right mounting bracket 5, first put that the 6, second anti-torsion suspension puts 7, crossbeam 8, electric machine controller 9, second attachment point 10, motor 11, retarder.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
The front cabin structure of a kind of pure electric automobile as shown in Figure 1, comprises the motor-retarder (10,11) in crossbeam 7, mounting assembly and dynamic assembly, mounting assembly comprises left suspension 1, the anti-torsion suspension of right suspension 3, first put 5 and second anti-torsion suspension put 6; Motor-retarder (10,11) is fixed on the below of crossbeam 7 by left mounting bracket and right mounting bracket 4, the left longeron of vehicle body is fixed in left suspension 1, the right vertical beam of vehicle body is fixed in right suspension 3, first anti-torsion suspension is put 5 and is fixed on subframe, and the second anti-torsion suspension is put 6 and is fixed on right suspension bracket.Left suspension 1 is connected with crossbeam 7 with right suspension 3.
