Problems solved by technology

[0002] In the related art, the dual-output shaft motor has only one casing, and only one set of stator and rotor drive sources are installed inside. Its disadvantage is that it can only output the same speed, and the shaft extensions at both ends cannot run at differential speeds.
Double back-to-back installation of double motors, the two motors are coaxially installed back to back, and mechanical transfers such as transfer boards or transfer bridges are provided between the motors. Because of the mechanical transfer, the installation structure is complicated, the cost increases, and the mechanical Increased resonance, many mechanical fixing points, low level of integration, uncompact structure, high manufacturing cost of dual motors

Abstract

The invention discloses a motor assembly and a vehicle. The motor assembly comprises: a plurality of motors, wherein each motor comprises a motor shell, a rotor and a stator, the rotor and the statorare arranged in the motor shell, and the plurality of motor shells are integrally formed to form a total shell. According to the motor assembly, multiple motors are arranged, the motor shells of the multiple motors are integrally formed and constructed into a total shell, all the motors work independently and do not influence one another, and the motor shells of the multiple motors are integrallyformed, so that the cost is low, and the motor assembly is compact in arrangement.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a motor assembly and a vehicle. Background technique [0002] In the related art, the dual-output-shaft motor has only one casing, and only one set of stator and rotor drive sources are installed inside. Double back-to-back installation of double motors, the two motors are coaxially installed back to back, and mechanical transfers such as transfer boards or transfer bridges are provided between the motors. Because of the mechanical transfer, the installation structure is complicated, the cost increases, and the mechanical Resonance increases, mechanical fixing points are many, and the level of integration is low, the structure is not compact, and the manufacturing cost of dual motors is high. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is ...
