Built-in differential mechanism of new energy automobile motor

Abstract

The invention relates to a built-in differential mechanism of a new energy automobile motor. The built-in differential mechanism comprises a differential mechanism shell, a right output shaft and a left output shaft are rotatably connected to the two ends of the differential mechanism shell respectively, and a right output assembly, a floating connection assembly and a left output assembly are sequentially arranged in the differential mechanism shell; the floating connection assembly comprises a magnetic floating assembly and a torque conversion assembly; and a drive circuit is also included. Two groups of permanent magnets and stator windings which are symmetrically arranged are utilized to realize equal-speed and equal-torque output of double wheels when a vehicle is in a common mode, and when the vehicle is trapped or slips, an iron core for wheel output can be switched by controlling an output circuit on the premise that power supply is not cut off, that is, wheel power is not lost. The two groups of stator windings connected in parallel are switched into the two groups of stator windings connected in series, and the current in a series circuit is equal, so that the two groups of stator windings can be forced to work under the same working condition.

Description

technical field [0001] The invention relates to a built-in motor differential of a new energy vehicle, which belongs to the field of new energy vehicles. Background technique [0002] Existing automotive differentials are huge in weight and complex in gear structure, especially for new energy vehicles, because there is no need for complex traditional structures, the motor can be directly placed in the front or rear, and output through a relatively simple transmission mechanism; Based on the driving principle of new energy vehicles, a set of differentials directly driven by motors suitable for new energy vehicles can be designed to reduce structural complexity and chassis weight; although in the prior art, the drive mechanism designed with dual motors , use a set of electronic control system to control two sets of motors designed in parallel, and use the independent rotation control of the two sets of motors to achieve output, but in the process of slipping, the loads of the ...
