Abstract
The utility model relates to an electric four-wheel vehicle power driven device, a motor shaft of an electric motor is connected with an input shaft of a speed transmission through a clutch which is arranged in a container of the speed transmission, the output end of the speed transmission is connected with a drive shaft of a front wheel, the end portion of the electric motor is fixed on the container of the speed transmission, a coupler is axially fixed on the container of the speed transmission, the coupler is circumferentially fixed with the motor shaft of the electric motor, the other end of the coupler is fixed with a stator of the clutch, a moving-strip of the clutch is circumferentially fixed with the input shaft of the speed transmission. The utility model changes the electric four-wheel vehicle power driven device into driving forward, simplifying transmission structure, increase the speed transmission and the clutch, capable of increasing and reducing speed of a motor vehicle to achieve the purpose of maintaining output power of a motor basically unchanged and operating current of the electric motor in nominal rating through a mechanical speed transmission, and to glide conveniently and reduce energy consumption. The driven device has compact structure, reasonable arrangement of components, and greatly improves driving property of the electric four-wheel vehicle.
Description
Technical field:
The utility model relates to the Power Drive Unit of electric four-wheeled automobile.
Background technology:
Present electric four-wheeled automobile generally is the direct rear-guard dynamic formula of motor with stepless speed regulation, adjusting moving velocity is by adjusting the electrical motor operating voltage, changing output power of motor realization speed adjusts, when resistance to motion increases or loads increase, infinite speed variation can't realize that output power of motor is constant, reduce motor speed, improve the purpose of output torque, electrical motor can only work overloadingly in such cases, be that the electric current increase exceeds rated current, electric motor overheating is impaired, and control part is big and impaired because of electric current equally.When automobile slided in the needs deceleration, electrical motor was wasted power by the automobile driven rotary.
Summary of the invention:
The purpose of this utility model provides a kind of electric four-wheel vehicle Power Drive Unit, can solve the relation between Vehicle Speed variation, resistance to motion variation and the driving motor horsepower output preferably, makes things convenient for vehicle to slide.
The purpose of this utility model realizes as follows: this electric four-wheel vehicle Power Drive Unit also relates to electrical motor and transmission shaft, the motor shaft of electrical motor connects input shaft by the power-transfer clutch that is in the case of transmission, and gearbox output connects the transmission shaft of front-wheel.
The electrical motor end is fixed on the case of transmission, and axial restraint unitor on the case of transmission, the motor shaft of unitor and electrical motor are circumferentially fixing, and the stator of the unitor other end and power-transfer clutch is fixed, and the moving plate of power-transfer clutch and input shaft are circumferentially fixing.
The utility model changes the electric four-wheel vehicle Power Drive Unit into before driving, has simplified drive mechanism; Increased change-speed box and power-transfer clutch, can reach to improve the speed of a motor vehicle or reduce the speed of a motor vehicle by mechanical speed change and keep the constant substantially and purpose of electrical motor working current in rated value of driving motor horsepower output, and conveniently slided, cut down the consumption of energy.This transmission structures compactness, parts connection and reasonable arrangement improve the electric four-wheel vehicle driveability greatly.
Description of drawings:
Fig. 1 is the whole connection structure scheme drawing of the utility model electric four-wheel vehicle Power Drive Unit.
Fig. 2 is electrical motor and a change-speed box bonded assembly structural representation in the utility model electric four-wheel vehicle Power Drive Unit.
The specific embodiment:
With reference to Fig. 1, Fig. 2, electrical motor 8 connects transmission shaft 13,14, two transmission shafts 13,14 by change-speed box 2 and connects two front driving wheels 15,16 respectively, and power-transfer clutch 3 is housed in the change-speed box 2.Driving motor 8 power are by motor rotor 12, are transferred to the input shaft 1 of change-speed box 2 through power-transfer clutch 3, pass to transmission shaft 13,14 again after by gear change in change-speed box 2, and then pass to left and right sides front driving wheel 15,16.
