A hub motor type electric vehicle with redundant function

Abstract

The invention provides a hub-motor-type electric vehicle with a redundancy function. The electric vehicle is characterized by adopting two batteries, four hub motor driving wheels, eight motor controllers and eight current sensors; each hub motor driving wheel is provided with a rotor assembly and a stator assembly; each rotor assembly includes a middle shell, a basic body, two groups of inner ring permanent magnets, two groups of outer ring permanent magnets, a left shell and a right shell; each left shell and the corresponding right shell are fixedly connected with the corresponding middle shell, and tires are installed on the outer walls of the middle shells; every two groups of outer ring permanent magnets and every two groups of inner ring permanent magnets are correspondingly fixed to the side wall, opposite to the corresponding basic body, of the corresponding middle shell; each left stator assembly includes a first base, a base limiting ring and a spoke-shaped connector, each right stator assembly comprises a second base and an annular connection disc, the connectors and the outer ends of the connection discs are all provided with annular stator grooves concentric to the corresponding stator axes, every two stator grooves are located between each inner ring permanent magnet and the corresponding outer ring permanent magnet, and the quantity of stator windings evenly distributed in each stator groove is equal, wherein every two stator windings are oppositely distributed in each stator groove.

Description

technical field [0001] The invention relates to a hub motor type electric vehicle with redundant functions, which belongs to the field of electric vehicles. Background technique [0002] With the increasing number of automobiles in China and the increasingly serious problems of energy security and environmental pollution, new energy vehicles have become one of the main directions of China's automobile technology development. In the past ten years, new energy vehicles have made significant contributions to energy conservation and emission reduction, and with the gradual maturity of key technologies of existing new energy vehicles and the further deterioration of environmental problems, people's requirements for energy conservation of new energy vehicles have also gradually increased. The evolution of state support policies can be seen. For example, in 2009, at the beginning of the new energy vehicle industrialization era, mild hybrid vehicles could receive state subsidies; i...

Problems solved by technology

[0005] The wheel-hub independent drive electric vehicle directly integrates the driving element, braking element, deceleration mechanism, etc. and arranges it inside the wheel. It belongs to the unsprung mass of the whole vehicle. , dust, etc., which will easily cause the stator, rotor or power supply of the motor to fail and the motor will stop running. When the car is running at high speed, the driving force of one side of the wheel will be abnormal, which will cause a large lateral force on the whole vehicle. Pendulum torque, which seriously affects the handling stability and safety of the vehicle
