Abstract

The invention provides a main / auxiliary motor power coupling assembly for bilateral independent drive vehicles, and the main / auxiliary motor power coupling assembly can be used for ensuring the accelerating and steering properties of bilateral independent drive vehicles. Because the left and right structures of a bilateral independent drive vehicle are completely same, the left structure is selected to be subjected to detailed introduction. In the invention, the torque coupling of a pair of fixed shaft gears is used as the power coupling of a main drive motor 4 and an auxiliary motor 11. The main drive motor 4 and the auxiliary motor 11 are arranged at the same side, and the shafts of the two motors are parallel, the power output by the auxiliary motor 11 passes through an auxiliary-motor speed reducer 10, an auxiliary-motor clutch 9 and an auxiliary-motor power input gear 8, the power output by the main drive motor 4 passes through a transmission shaft 5, and the torque coupling of the two motors is realized at a power coupling gear 6.

Description

technical field [0001] The invention belongs to the technical field of power assembly components, and in particular relates to a main and auxiliary motor power coupling assembly of a double-sided independently driven vehicle. Background technique [0002] Bilaterally independently driven vehicles mean that the motors on the left and right side of the vehicle respectively drive the left and right driving wheels to drive in a straight line, and the steering is realized by the speed difference generated by the left and right motors. The significant advantages of this drive scheme make it a promising application prospect for electric drive vehicles. The independent drive of the two-sided motors is not only flexible in overall layout, but also easy to implement the vehicle control strategy. At present, most vehicles independently driven by double-sided motors connect the drive motor directly to the side drive or add a gearbox between the drive motor and the side drive. Due to t...
