Another wheel 303 absorbs energy, to generate electricity.
Anti-skidding synchronizer 503 is arranged to optionally synchronize the pair of wheels 203,303, so that the pair of wheels
203,303 synchronous rotary, in other words, (the i.e. anti-skidding synchronizer 503 after anti-skidding synchronizer 503 synchronizes the pair of wheels 203,303
In engagement state), it is formed between the pair of wheels 203,303 and connects firmly form, thus synchronous rotary, it will not differential rotation.And
When anti-skidding synchronizer 503 is in an off state, the first motor generator 201 and the second motor generator 301 can drive respectively
Corresponding wheel is moved with different rotational speeds, realizes the differential rotating function of two wheels 203,303, certainly, first is electronic
Generator 201 and the second motor generator 301 can also drive the pair of wheels 203,303 with identical rotational speed.
Power drive system 100 according to an embodiment of the present invention as a result, passes through the first motor generator 201 of setting and the
Two motor generators 301 individually drive two wheels 203,303, so as to realize the differential of two wheels 203,303
Rotation, and when occurring in which a wheel-slip phenomenon, anti-skidding synchronizer 503 can synchronize two wheels 203,303 so that
Two wheels 203,303 synchronous rotaries drive two wheels 203,303 to transport jointly after realizing the power coupling of two motors output
It changes a job work, improves wheel-slip phenomenon, improve the handling capacity of vehicle.Particularly, in the feelings for occurring in which a wheel-slip
Under condition, the power of the first motor generator 201 and the second motor generator 301 can drive the vehicle that another does not skid jointly
Wheel, so that another wheel for enabling this not skid obtains the power of two motors, substantially improves slipping phenomenon.
In short, power drive system 100 according to an embodiment of the present invention can be not provided with conventional power transmission system
Mechanical no-spin lockup structure, but traditional machine but functionally may be implemented by the synchronous effect of anti-skidding synchronizer 503
The function of tool formula no-spin lockup so that the structure of power drive system according to an embodiment of the present invention 100 it is more compact,
Cost is lower.
