Abstract

The invention belongs to the technical field of electric vehicles, and particularly relates to a dual-motor power system and an electric vehicle. The dual-motor power system comprises a first motor, a second motor, a differential mechanism, a one-way clutch and a transmission, wherein the transmission comprises a first output shaft, a second output shaft, an intermediate shaft and a controllable torque transmission device; a driving shaft of the first motor is connected with the first output shaft, and a driving shaft of the second motor is connected with the second output shaft; the controllable torque transmission device is connected with the first output shaft; and the one-way clutch is installed on the intermediate shaft, and the transmission is connected with automobile wheels through the differential mechanism. According to the dual-motor power system, the reverse dragging resistance during normal running of the vehicle is reduced while the power performance is enhanced, and then the economical efficiency is improved. Meanwhile, the integration degree of the dual-motor power system is high, and the installation space is saved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a dual-motor power system and an electric vehicle. Background technique [0002] In the field of electric vehicle drive technology, in order to take into account the needs of both power and economy, a single-motor two-speed power system is usually used to output power. However, the single-motor two-speed power system usually requires a large gear ratio when shifting gears, which will cause a large speed difference between the two ends of the shifting element when shifting gears, resulting in increased difficulty in shifting gears, which in turn leads to power loss. Prolonged interruption or severely worn shift elements. [0003] In the prior art, the dual-motor power system is increasingly used in high-power pure electric vehicles because of its strong power and the fact that it does not require gear shifting or can greatly reduce the difficulty of gear shifting.
