Abstract
The invention provides a driving mechanism of an electric vehicle. The driving mechanism comprises a driving motor and is characterized in that through a clutch the driving motor connects a transmission system which is provided with different shifts. According to the invention, a freewheel clutch is arranged between the driving motor and a trailing wheel. Through the transmission system which is provided with different shifts, power is transmitted to the trailing wheel, thus the speed change of the electric vehicle is realized. When riding the electric vehicle, the shift of the electric vehicle can be changed according to road condition to maximize the energy efficiency of the driving mechanism and guarantee the current of the driving motor in a normal scope of application. Thus the service life of the driving motor is prolonged and the mileage of the electric vehicle is increased.
Description
Technical field
The present invention relates to a kind of driving mechanism, relate in particular to a kind of electric motor car driving mechanism.
Background technology
At present, electric motor car is normally used to be the hub-type motor, can't realize speed change, makes electric motor car use a gear ratio on level road when climbing and travelling, and therefore, the utilance of motor is not high.
Summary of the invention
The object of the present invention is to provide a kind of electric motor car driving mechanism that can realize many gears speed change.
The object of the present invention is achieved like this, and a kind of electric motor car driving mechanism comprises drive motors, it is characterized in that, described drive motors connects with the drive system that is provided with different gears by clutch.
Above-mentioned drive system comprises transmission main shaft and transmission countershaft and engagement, and above-mentioned clutch is a freewheel clutch, the motor shaft engagement that the startup of described freewheel clutch is circled or whirl in the air and is enclosed within on the described transmission main shaft and passes through gap bridge tooth and drive motors.
Above-mentioned freewheel clutch comprises isolator, and described isolator outer cover is sleeved on the above-mentioned transmission main shaft by rectangular spline.
Above-mentioned freewheel clutch is connected with the gap bridge tooth by the driven tooth that is arranged on the above-mentioned transmission main shaft.
Above-mentioned transmission main shaft comprise the main shaft mandrel and be arranged on the main shaft mandrel one grade of gear, intermediate gear, third gear and fourth gear and respectively with the countershaft mandrel of above-mentioned transmission countershaft on the one grade of tooth, second gear tooth, third gear tooth and the engagement of fourth gear tooth that are provided with.
Above-mentioned driven tooth is arranged on the driven tooth axle sleeve, is provided with bimetal liner in the described driven tooth axle sleeve.
When drive motors transmitted power by motor shaft, motor shaft was given driven tooth transmission of power by the gap bridge tooth, and driven tooth drives boot disk and rotates, simultaneously, can only rotate to a direction under the effect of isolator, and drive the transmission main shaft rotation, final power passes to trailing wheel by transmission countershaft; Under descending or loosening handle state, because no current offers drive motors, at this moment under the effect of isolator, drive motors becomes inactive state, trailing wheel drives transmission main shaft, transmission countershaft rotates, and the magneto resistance effect that drive motors produced can not produce any resistance to trailing wheel.
The present invention has following beneficial effect, the present invention is provided with freewheel clutch between drive motors and trailing wheel, give trailing wheel by the drive system that is provided with different gears with transmission of power, realized the speed change of electric motor car, can arbitrarily change gear according to road conditions when riding, make the efficiency maximization of driving mechanism, can guarantee that the electric current of drive motors is in normal operating range all the time simultaneously, prolong the useful life of drive motors, increased distance travelled.
