Problems solved by technology

[0002] In the power system of the existing electric vehicle, there is generally only one set of power motors. When the vehicle is starting, the instantaneous traction force required is larger, and the starting process of a single motor will be relatively slow. Similarly, the single motor provides The power is limited. When it is necessary to climb a slope, the power provided by a single motor is also relatively limited, so it will make it difficult to climb a slope, or directly cannot pass a road with a large slope, which will limit the use of the car to a certain extent.

Abstract

The invention discloses a dual-motor power system. The dual-motor power system comprises a first power transmission assembly, a second power transmission assembly and a planetary gear structure. According to the power system, when the vehicle is in the starting state or the climbing state, simultaneous driving is conducted through the double motors, provided power is larger, rapid starting and climbing limitation can be achieved, and the performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a dual-motor power system. Background technique [0002] In the power system of the existing electric vehicle, there is generally only one set of power motors. When the vehicle is starting, the instantaneous traction force required is larger, and the starting process of a single motor will be relatively slow. Similarly, the single motor provides The power is limited. When it is necessary to climb a slope, the power provided by a single motor is also relatively limited, so it will make it difficult to climb a slope, or directly cannot pass a road with a large slope, which will limit the use of the car to a certain extent. Contents of the invention [0003] The object of the present invention is to address the above shortcomings and provide a dual-motor power system. The power provided by the dual-motors is stronger, which solves the limitations of starting and climbing. ...
