Wheel hub motor

Abstract

The invention relates to the technical field of automobiles, and especially relates to a wheel hub motor. The wheel hub motor comprises a motor main body, a motor controller and a decelerator, the motor controller and the decelerator are both arranged inside the motor main body, the motor main body comprises a motor shaft, the motor controller is disposed at the input side of the motor shaft and is connected with the input end of the motor shaft, the decelerator is disposed at the output side of the motor shaft, the input end of the decelerator is connected with the output end of the motor shaft, and the output end of the decelerator is connected with the shaft end of a wheel hub. According to the invention, the motor controller and the decelerator are respectively integrated into the motor main body, the overall construction of a driving system is simplified, the transmission efficiency loss at each stage and waste of energy, caused by many connection relations and complex transmission structures are avoided, energy conservation is facilitated, the transmission efficiency is improved, the driving system is arranged to be simpler and more compact, the composition of a motor driving structure is complete, and driving of a left wheel and a right wheel of a vehicle body can be independently controlled.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hub motor. Background technique [0002] With the gradual withering of oil resources and the gradual increase of air pollution, the society is increasingly calling for new energy vehicles, including pure electric, hybrid, plug-in, fuel cell and other forms of vehicles. New energy vehicles greatly reduce the impact on Oil dependence and air pollution. [0003] Compared with traditional internal combustion engine vehicles, new energy vehicles have undergone tremendous changes in both the general layout of the vehicle and the drive system assembly due to the different forms of energy supply. The drive system assembly is crucial to the vehicle. Important, it not only undertakes the carrying function and driving function, but also directly determines the safety and comfort performance of the vehicle. [0004] At present, the drive system assembly of traditional diesel locomoti...
