Embodiment Construction

[0043] 1. The present invention, the so-called motor drive system with vehicle speed adaptability, adopts a dual-motor drive mode. Its topological structure is shown in Fig. 2. Both the first motor (1) and the second motor (3) have a double-end shaft output structure. Between the first motor (1) and the second motor (3), there is a speed reducer (5) and a one-way clutch (7) with a torsional vibration damper. The output end (1-1) of the motor (1) is connected with the input end (5-1) of the reducer (5); the output end (5-2) of the reducer is connected with the one-way clutch with torsional vibration damper The driving end (7-1) of (7) is connected; The driven end (7-2) of the one-way clutch (7) with the torsional vibration damper and the output end (3-2) of the motor 2 (3) connect. The function of the one-way clutch (7) with torsional vibration damper is to engage or disengage the motor (1) and reducer (5) with the motor (3). The motor (1) and the motor (3) are AC motors or...

Abstract

The invention involves a electric motor drive system with the capacity to adapting to the speed and its controlling method. The system includes a electric motor drive system controller, the first electric motor, the first electric motor controller, the second electric motor, the second electric motor controller. It is characterized by: the first and the second electric motors both have output axis of their two ends, a output axis of the first electric motor is connected with a output axis of the second electric motor through at least one speed reducer; the electric motor drive system controller is linked with the first electric motor controller and the second electric motor controller through signal cables respectively, the first electric motor controller is connected with the first electric motor through power cables, and the second electric motor controller is connected with the second electric motor through power cables. Its advantages are: it can change the mode of drive system automatically according to the vehicle's speed, power, traction demand and the driving conditions to meeting the driving demands such as climbing in low-speed, running in middle or high speed, braking, reversing and so on, thus it adapts various operating conditions automatically. The drive system can be used in pure electric vehicles, fuel cell electric vehicles and hybrid power electric vehicles and other various vehicles driven by electric motor.
