Abstract
The utility model discloses an electric automobile driven by dual wheel rims, which comprises a motor, a chassis, an automobile body and the like, and is characterized in that the driving is realized by directly transmitting to a half shaft through a speed-reducing motor and the half shaft transmits to a driving wheel. Two brushless speed-reducing motors are respectively arranged at the front end and the rear end of a rear axle and directly connected with the half shaft; the speed-reducing ratio of the speed-reducing motors is 8:1 to12:1; and an electronic differential controller is arranged on a bearing beam and connected with the motor through a lead. The electric automobile driven by dual wheel rims has the advantages of high driving efficiency, energy source saving, large starting torque, good climbing capability and acceleration performance, simplified finished automobile structure, low manufacturing cost and the like.
Description
Affiliated technical field
The utility model relates to a kind of electronlmobil, and especially the two-wheel limit of motor direct-drive drive wheel drives electronlmobil.
Background technology
Existing automobile mechanical transmission is bent axle-power-transfer clutch-change speed gear box-transmission shaft-back axle-diff-semiaxis-wheel, and this type of drive driving efficiency is low, have only about 76%, and energy resource consumption is big.
Summary of the invention
Provide a kind of driving efficiency height, the saving energy, the rational two-wheel of compact conformation limit to drive electronlmobil in order to overcome disadvantages of background technology part the utility model.
The technical scheme in the invention for solving the technical problem is based on existing automobile, just change mechanical driving part, do not establish power-transfer clutch, change speed gear box, diff on transmission shaft and the back axle, two reducing motors are installed in the back axle front-end and back-end respectively, directly link to each other with semiaxis, drive two drive wheels respectively, double-motor can be that permanent magnetism is brushed DC machine especially, alternating-current variable frequency motor, permagnetic synchronous motor, reluctance motor, various motors directly are contained on the retarder of the two poles of the earth deceleration low noise respectively, constituting various reducing motors, is best with the permanent-magnet brushless DC electric machine.
The beneficial effects of the utility model are:
1, two reducing motors are contained in the front-end and back-end of back axle respectively, drive two semiaxis respectively and drive the trailing wheels rotation, have improved system's driving efficiency, energy savings, starting torque is big, hill climbing ability is strong, acceleration capability is good;
2, owing to do not establish power-transfer clutch, change speed gear box, transmission shaft etc., simplified complete vehicle structure, made its compactness rational in infrastructure, low cost of manufacture;
3, stepless time adjustment is simple to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model drive system structure scheme drawing
Among the figure: 1, motor, 2, back axle, 3, drive wheel, 4, semiaxis, 5, retarder.
The specific embodiment
The utility model is based on existing automobile, just changes mechanical driving part, has omitted parts such as power-transfer clutch, change speed gear box, as shown in the figure, is installed in the front-end and back-end of back axle (2) respectively with two reducing motors (1).Reducing motor is the last formation of retarder (5) that motor directly is contained in the two poles of the earth deceleration low noise.The reducing motor reduction ratio is in 8: 1～12: 1 the scope.The automobile of this double-motor structure, its double-motor can adopt permanent-magnet brushless DC electric machine, alternating-current variable frequency motor, permagnetic synchronous motor, reluctance motor.The utility model is a permanent-magnet brushless DC electric machine, this power of motor is big, torque density is big, volume is little, in light weight, low-speed performance good, startup and overload torque are big, uses this motor to be the best at present.Retarder (5) links to each other with drive wheel (3) by semiaxis (4).The transmission of this structure is directly to pass to semiaxis (4) by motor (1) and retarder (5), passes to drive wheel (3) by semiaxis (4), has improved the driving efficiency of electronlmobil greatly.For realizing that better double-motor by electronic differential direct drive wheel, to improve the vehicle electric system driving efficiency, is provided with an electronic differential controller on the automobile bearing beam, it links to each other with motor by lead.
Claims (3)
