Abstract
An in-wheel motor system, wherein the rotating side caseof an in-wheel motoris connected to a wheelby a flexible couplingcomprising a plurality of hollow disk-like platesA toC and direct-acting guidesA andB, the non-rotating side caseof the motoris connected to a knuckleby a damping mechanismfor connecting the non-rotating side caseof the motor to the knucklewhich is a frame dress-up part of the vehicle, comprising two platesandwhose moving directions are limited to the vertical direction of the vehicle by direct-acting guidesand which are interconnected by first spring elementswhich move in the vertical direction of the vehicle and damperswith a spring element, each comprising a damperand a second spring element connected to the damperin series and arranged parallel to the first spring elements, whereby the drive force of the in-wheel motorcan be transmitted to the wheelwithout fail and the road holding properties of a vehicle can be further improved by greatly reducing variations in the ground-contact load of a tire.
