Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The present invention provides a dual-motor drive system, including a housing, see for details figure 2 , which differs from the prior art in that: first and second motors are respectively provided in the casing, the first motor is used as the main drive motor to output kinetic energy; the second motor is an auxiliary drive motor, and the output shaft of the second motor passes through The one-way clutch is connected with the output shaft of the first motor, and is used for providing auxiliary output k...

Abstract

The invention relates to a dual-motor driving system. A shell is internally provided with a first motor and a second motor separately, and the first motor serves as a main driving motor and is used for outputting kinetic energy; the second motor is an auxiliary driving motor, and an output shaft of the second motor is connected with an output shaft of the first motor through a one-way clutch and used for providing auxiliary output kinetic energy for the first motor. The connection between the first motor and the second motor is adjusted through the one-way clutch so that the maximum output power can be provided in the speed-up stage of a vehicle, and meanwhile, in the high-speed running stage of the vehicle, only the main driving motor provides the output power to ensure the maximum vehicle speed. Meanwhile, the system is simple in structure, reasonable in layout and low in manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of drive systems, in particular to a dual-motor drive system, in particular to a dual-motor drive system for pure electric vehicles and a method for using the same. Background technique [0002] Existing pure electric vehicles generally use a single-motor drive system or a dual-motor drive system, and such a single-electric drive system generally has the problem of relatively poor power performance. [0003] And the existing dual-motor drive system is also relatively simple, see figure 1 , Two motors are used to output power through the same gear. This dual-electric drive system basically uses a single-speed gearbox, and the power output mode is relatively simple. It is difficult to take into account the requirements of power, efficiency, and maximum speed. [0004] Because it is a single-speed gearbox, the gear ratio is fixed. If you need to improve power, you need to increase the speed ratio; if ...
