The power distribution of distributor is controlled.
Provide the benefit that: (1) instant invention overcomes the shortcoming of tradition wheel motor four-wheel drive system, use machinery to realize 4
Power coupling between wheel motor, under cross-country operating mode, the wheel motor power losing adhesion property can be by inner couplings
Machinery is delivered to the wheel that adhesion property is good, substantially increases power utilization and the acceleration of wheel motor.Exist simultaneously
Power coupling machinery adds the electrokinetic moment distributor for the distribution of antero posterior axis power, shaft space difference speed and axle can be realized
Between the initiative and flexible distribution of power.
(2) wheel motor is arranged in differential mechanism outfan, after single wheel runs out of steam, does not interferes with opposite side wheel
Power exports, and can save differential lock between wheel.
(3) electrokinetic moment distributor can realize the active continuous dispensing of between centers power, and the torque motor of available less moment of torsion is complete
Becoming the flexible allocation of between centers power, the torque motor of electrokinetic moment distributor exports positive torque by difference square planetary mechanism, side,
The negative torque of opposite side output, can realize the power continuous stepless distribution between antero posterior axis.Controlled by the active of between centers power, carry
The dynamic acceleration of high car load, and the adhesion property on road surface can be made full use of.When torque motor does not works, difference square planetary structure
Can be as shaft space difference speed mechanism, it is ensured that the motor coordination during high vehicle speeds, reduce the abrasion of tire.
(4) under normal driving cycle, 4 wheel motors can control the output driving moment of each motor, it is achieved lateral torque is fixed
To function, improve the lateral control stability of vehicle.
(5) under limiting condition, by both sides wheel motor Positive-Negative Action, differential skid steer function can be realized, improve vehicle
Turn to mobility.
