The invention relates to a differential electric driver and belongs to the technical field of differential electric drivers. A split turbocharged speed reducer differential electric driver comprises a motor shell and a motor shaft, and is characterized in that: the driver also comprises a shell of a reduction booster; a shell of a differential mechanism in the shell is fixedly connected with the shell of the reduction booster through a bearing; the periphery of the motor shaft is provided with a main driving gear fixedly connected therewith; the main driving gear is in transmission connection with a main driving planetary gear arranged on the periphery of the main driving gear through a main driving planetary gear shaft; the main driving planetary gear is meshed with a turbine main reduction gear fixedly connected with the shell of the differential mechanism; and the turbine main reduction gear is connected to a speedometer gear sensor through a speedometer driving ring gear arranged on one side thereof. The differential electric driver improves the output torque of an axle shaft of the differential mechanism, greatly improves climbing capacity of an electrocar, changes the phenomenon that the prior electrocar has high power consumption when starting, decreases multiple connecting links, reduces the noise of the electrocar, and leads the development direction of future electrocars.
Description
technical field [0001] The invention relates to a split type turbocharger reducer differential electric drive machine, belonging to the technical field of differential electric drive machine structure. Background technique [0002] At present, the existing electric vehicles have insufficient climbing ability and consume a lot of power when starting. Due to the limitations of the structural connection of the existing electric vehicles, a large noise is often generated at the connection part of the transmission shaft and the deceleration rear axle, which makes the electric vehicle The overall performance and life of the car will be adversely affected. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a method that can greatly enhance the climbing ability of the electric vehicle, effectively reduce the large power consumption at the start of the existing electric vehicle, and redu...
