AI Technical Summary

Problems solved by technology

[0007] Due to the large radius of the motor, the traditional in-wheel drive device can double the torque without a reducer, or use a reducer to double the torque, but it needs to increase the specification of the motor or the wheel, resulting in Necessity to improve related issues

Abstract

The present invention provides an in-wheel driving device, comprising: a spoke plate built in a wheel, a wheel hub which is arranged in combination with the spoke plate and capable of rotating, and a knuckle which is combined with the wheel hub and fixedly arranged on a suspension connected with the wheel and a vehicle body; a motor part combined with the knuckle for generating motive power; and a reducer connected with the motor part and the wheel hub for transmitting the motive power generated by the motor part to the wheel hub; wherein, the wheel hub comprises a wheel hub inner ring protruding at a central part of the knuckle and a wheel hub outer ring which wraps the wheel hub inner ring from an outer side and is combined with the wheel; the reducer comprises a planet gear reducing body rotating along with the motor part, and a counter gear reducing body which rotates along with the planet gear reducing body and is connected with an upper part position of the wheel hub outer ring.

Description

technical field [0001] The present invention relates to an in-wheel drive device, in particular to an in-wheel drive device with a motor built into the wheel to achieve torque multiplication with a small size. Background technique [0002] Today, with the depletion of fossil fuels, electric vehicles that use electricity stored in batteries to drive motors have attracted more attention than vehicles using fossil fuels such as gasoline and diesel, and their development has also become more active. [0003] Electric vehicles are divided into pure electric vehicles that use the power stored in rechargeable batteries to drive motors, solar battery vehicles that use photovoltaic cells to drive motors, fuel cell vehicles that use fuel cells that use hydrogen fuel to drive motors, and fossil fuels that use fossil fuels to drive engines and electricity. The engine and motor that drive the motor are used together in a hybrid vehicle. [0004] Generally speaking, the driving device lo...
