Pure electric timely synchronous four-wheel drive force assembly

Abstract

The invention discloses a pure electric timely synchronous four-wheel drive force assembly. A motor shaft of a drive motor is in transmission connection with an input shaft of a reduction gearbox; anelectromagnetic clutch gear box comprises a clutch box body, and an electromagnetic clutch gear set, a clutch toothed chain wheel, a front driving shaft and a rear driving shaft which are positioned in the clutch box body; the front driving shaft and the rear driving shaft are installed in the clutch box body, and an output shaft of the reduction gearbox is in transmission connection with the reardriving shaft. A driving disc of the electromagnetic clutch gear set is installed on the rear driving shaft, a driven disc of the electromagnetic clutch gear set is installed on the rear driving shaft through a bearing, the clutch toothed chain wheel is connected to the driven disc of the electromagnetic clutch gear set, and the clutch toothed chain wheel is installed on the rear driving shaft through a bearing. Four-wheel drive can be synchronized in time, and power output is stable and reliable. The pure electric timely synchronous four-wheel drive force assembly is suitable for high-end pure electric off-road vehicles and pure electric high-end passenger cars, and is a preferred four-wheel synchronous drive power system for various special pure electric vehicles.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically relates to a pure electric timely synchronous four-drive power assembly. Background technique [0002] my country is the country with the largest number of cars in the world. With the enhancement of environmental protection awareness, it has become a basic national policy to control fuel vehicles and vigorously develop new energy vehicles to protect human ecological environment. [0003] At present, the existing pure electric vehicles at home and abroad simply use motors and electronic controls to replace the engines of fuel vehicles, and batteries to replace the combustible fuel of fuel vehicles. [0004] The existing pure electric four-wheel drive system is generally implemented by dual motors driving the front and rear wheels. The electric four-wheel drive system mainly controls the torque distribution between the front and rear axles and wheels through the ECU,...

AI Technical Summary

Problems solved by technology

The program simulation control of the software is very difficult, it is difficult to make correct decisions for the working conditions of the vehicle, and even the front and rear drive synchronization problems in complex road conditions are also difficult to solve

It is difficult to effectively control the vehicle under complex road conditions such as vehicle starting, heavy load, climbing, high speed, ice and snow roads, muddy roads, etc.
