Abstract
The utility model provides an electromechanical bis-control variable electric vehicle which comprises a vehicle body, storage batteries arranged in the vehicle body, a motor, a motor controller and drive axle driving wheels to rotate. A mechanical gearing device which consists of a clutch, a mechanical gear and a transmission shaft which are respectively connected with the motor and the drive axle is arranged between the motor and the drive axle. The utility model serves to control vehicle speed dually by the motor controller and the mechanical gear and controls the vehicle speed to change in a comparatively large range. The electric vehicle is provided with certain grading capability at low speed and can normally drive in bad roads.
Description
Technical field
The utility model relates to a kind of transmission and control setup of elec. vehicle.
Background technology
Along with the raising of The development in society and economy and life, the elec. vehicle of environment-friendly type, more and more general as the use of vista car, golf cart etc.Many are come, thisly be used as power with the storage battery stored energy, and be to adopt electric controller to control the speed of battery-driven car by electric motor driven battery-driven car always.Its principle of work is: the storage battery outgoing current enters electrical motor through electric motor speed controller, by the electrical motor output torque, behind belt wheel or gear reduction, pass to drive axle, drive wheels is rotated, but because the speed of this vehicle can only rely on electric controller to control, so the velocity variations scope is little, a little less than the hill climbing ability, can not adapt to road conditions complicated and changeable, so rideability is poor.
Summary of the invention
The purpose of this utility model provides that a kind of speed control range is big, and hill climbing ability is strong, complex road surface can cruising battery-driven car.
Dynamo-electric two control speed change battery-driven cars that the utility model provides, comprise vehicle body, be installed in the drive axle that storage battery, motor, electric controller and drive wheels on the vehicle body are rotated, between motor and drive axle, be provided with mechanical variable speed device, this device is made up of power-transfer clutch, mechanical transmission and transmission shaft, and power-transfer clutch is connected with drive axle with motor respectively with transmission shaft.
The utility model has increased a mechanical variable speed device owing to adopted said structure in the electrical motor back, not only can pass through the motor controller controls speed of a motor vehicle, can also control the speed of a motor vehicle by mechanical transmission, thereby controllable speed changes in a big way.With the low speed scanning frequency time, can produce bigger moment of torsion, make battery-driven car have the certain climbing ability, can be on the road surface of complexity cruising.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.As shown in the figure, storage battery 7, motor 2 and electric controller 1 are installed on the vehicle body of battery-driven car, mouth at motor 2 connects the mechanical variable speed device of being made up of power-transfer clutch 3, mechanical transmission 4 and transmission shaft 5, and the other end of transmission shaft 5 connects the drive axle 6 that drive wheels is rotated.Its principle of work is: electric current exports behind the electric controller input motor again to by storage battery, and the moment of torsion that this moment, electrical motor was exported passes to drive axle through the transmission shaft of mechanical variable speed device.When select higher mechanical speed change than the time, can produce low-speed big and do work, have the certain climbing ability when battery-driven car travels like this, strengthened the through performance of travelling of road greatly; When vehicle when good road surface is travelled, then select lower mechanical speed change ratio, to improve the speed of a motor vehicle.In addition, under the effect of electric controller,, thereby regulate the moment of torsion and the speed of a motor vehicle,, promptly realize the bifunctional control speed effect of electric controller and mechanical speed adjuster to adapt to the different road conditions of travelling by the adjusting size of current.Mechanical variable speed device of the present utility model can be selected mechanical variable speed device commonly used on the common vehicle for use, does not give unnecessary details in addition.
Claims (1)
1, the two control of a kind of electromechanics speed change battery-driven car, comprise vehicle body, be installed in the drive axle (6) that storage battery (7), motor (2), electric controller (1) and drive wheels on the vehicle body are rotated, it is characterized in that: between motor (2) and drive axle (6), be provided with mechanical variable speed device, this device is made up of power-transfer clutch (3), mechanical transmission (4) and transmission shaft (5), and power-transfer clutch (3) is connected with drive axle (6) with motor (2) respectively with transmission shaft (5).
