Abstract

An in-wheel motor unit may include: a rim member having a tire installed along an outer circumference thereof; a spoke connected to the rim member and rotated with the rim member; a motor part locatedin a mounting space formed by the rim member and the spoke, and configured to generate rotational power through power supply, and rotate the spoke; a knuckle part connected to the motor part and configured to support a suspension part; and a hub part having one side fixed to the spoke and the other side connected to the knuckle part, and configured to rotatably support the spoke. According to thepresent disclosure, the motor part is located inside a wheel member including the rim member and the spoke, and a brake portion and the hub part are located in the motor part. Thus, it is possible toimprove the degree of freedom of design while a suspension part does not interfere with the in-wheel motor unit.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to an in-wheel motor unit, and more particularly, to an in-wheel motor unit in which a portion related to the in-wheel motor does not interfere with a chassis portion. Background technique [0002] Since fossil fuels are in danger of being exhausted, electric vehicles, which drive motors using electric energy stored in batteries, have been developed instead of vehicles using fossil fuels such as gasoline and diesel. [0003] Electric vehicles are classified into pure electric vehicles that use only the electrical energy stored in a rechargeable battery to drive a motor, solar battery vehicles that use a photovoltaic cell to drive a motor, fuel cell vehicles that use a fuel cell that utilizes hydrogen fuel to drive a motor, and those that use A hybrid vehicle in which a fossil fuel drives the engine and uses electricity to drive both the engine and the motor. [0004] Generally, in-wheel motor unit...
