Abstract
The utility model discloses a controlling device for the four wheel drive of an electric automobile, which comprises a left front wheel motor, a right front wheel motor, a left rear wheel motor, a right rear wheel motor, a left front wheel motor controller, a right front wheel motor controller, a left rear wheel motor controller and a right rear wheel motor controller which are respectively and electrically connected with the left front wheel motor, the right front wheel motor, the left rear wheel motor and the right rear wheel motor, a front wheel electronic differential gear electrically connected with the left front wheel motor controller and the right front wheel motor controller, a rear wheel electronic differential gear electrically connected with the left rear wheel motor controller and the right rear wheel motor controller, a steering signal generator which is controlled by a steering wheel and electrically connected with the front wheel electronic differential gear and the rear wheel electronic differential gear. The controlling device has the advantages that the electric automobile can adopt four-wheel type to drive when adopting the controlling device of the utility model, the acceleration performance is good and running, stopping and starting in downtown area are convenient without influencing others drive speed.
Description
Technical field
The utility model relates to a kind of control setup, relates in particular to the control setup that a kind of four wheels of electric automobile drives.
Background technology
Electronlmobil is as a kind of pollution-free green environmentally friendly vehicle, and extremely automotive field personage's concern also receives the personage's of every aspect concern, and many in the world countries all develop sparing no effort.But the small-sized electric automobile is generally taked two-wheel drive at present, the power of drive motor is little, moving velocity particularly acceleration capability is not very desirable, particularly travels in the business district, and traffic lights are many, vehicle is many, the starting of stopping is also many, and acceleration capability is poor, not only feels not well, even can influence other people moving velocity, have influence on the magnitude of traffic flow in city.
The utility model content
The utility model is to overcome above-mentioned weak point, and purpose is to provide a kind of control setup of four wheels of electric automobile driving, can drive four-wheel simultaneously, has solved the deficiencies in the prior art part.
The utility model is to achieve the above object by the following technical programs: the control setup that a kind of four wheels of electric automobile drives comprises the near front wheel motor, the off front wheel motor, the left rear wheel motor, the off hind wheel motor, respectively with the near front wheel motor, the off front wheel motor, the left rear wheel motor, the near front wheel electric machine controller that the off hind wheel motor is electrically connected, the off front wheel electric machine controller, the left rear wheel electric machine controller, the off hind wheel electric machine controller, with the near front wheel electric machine controller, the front-wheel E-Diff that the off front wheel electric machine controller is electrically connected, with the left rear wheel electric machine controller, the trailing wheel E-Diff that the off hind wheel electric machine controller is electrically connected, with the front-wheel E-Diff, the turn sign producer of the bearing circle control that the trailing wheel E-Diff is electrically connected.
The beneficial effects of the utility model: 1) adopt control setup of the present utility model, electronlmobil can adopt the mode of four-wheel, the acceleration capability ideal, and the parking starting of travelling in the business district is convenient, can not influence other people moving velocity.
Description of drawings
Fig. 1 is the fundamental diagram of the control setup that a kind of four wheels of electric automobile drives among the utility model embodiment 1;
The specific embodiment
The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:
Embodiment 1: as shown in the figure, the control setup that a kind of four wheels of electric automobile drives comprises the near front wheel motor, the off front wheel motor, the left rear wheel motor, the off hind wheel motor, respectively with the near front wheel motor, the off front wheel motor, the left rear wheel motor, the near front wheel electric machine controller that the off hind wheel motor is electrically connected, the off front wheel electric machine controller, the left rear wheel electric machine controller, the off hind wheel electric machine controller, with the near front wheel electric machine controller, the front-wheel E-Diff that the off front wheel electric machine controller is electrically connected, with the left rear wheel electric machine controller, the trailing wheel E-Diff that the off hind wheel electric machine controller is electrically connected, with the front-wheel E-Diff, the turn sign producer of the bearing circle control that the trailing wheel E-Diff is electrically connected.
After adopting control setup of the present utility model, motor is all served as driving by the brushless motor that can independently travel, each drive motor provides electric power by the electric power controller that matches, preceding two-wheeled and back two-wheeled all respectively are one group, control by E-Diff separately, the differential signal that sends when being rotated by bearing circle is after 2 the E-Diff modulation in front and back, be input to separately in the front and back wheel electric power controller, the symbol electronlmobil of realization four-wheel turns to the differential of requirement.
Claims (1)
1, the control setup that a kind of four wheels of electric automobile drives is characterized in that comprising the near front wheel motor, the off front wheel motor, the left rear wheel motor, the off hind wheel motor, respectively with the near front wheel motor, the off front wheel motor, the left rear wheel motor, the near front wheel electric machine controller that the off hind wheel motor is electrically connected, the off front wheel electric machine controller, the left rear wheel electric machine controller, the off hind wheel electric machine controller, with the near front wheel electric machine controller, the front-wheel E-Diff that the off front wheel electric machine controller is electrically connected, with the left rear wheel electric machine controller, the trailing wheel E-Diff that the off hind wheel electric machine controller is electrically connected, with the front-wheel E-Diff, the turn sign producer of the bearing circle control that the trailing wheel E-Diff is electrically connected.
