Zusammenfassung: | To provide an in-wheel motor type vehicle drive device that can suppress deterioration of engagement between a motor gear and a ling gear.SOLUTION: A vehicle drive device 100 comprises: a drive shaft D1 provided at a wheel W2 of a traveling wheel W to transmit driving force to the wheel; three or more induction motors 1 each including a motor gear 12 provided with an outer gear 12a and generating the driving force for driving the traveling wheel, the induction motors 1 being along a circumferential direction of the drive shaft and at least some of the three or more induction motors being arranged in an inner space N of the wheel; and a ring gear 50 which is driven by engagement with the respective motor gears of the three or more induction motors to thereby drive the drive shaft. The ring gear is a separate member separated from the drive shaft side so as to be movable in a radial direction and an axial direction of the drive shaft relative to the drive shaft, and is structured so that its position in the radial direction of the drive shaft is determined by being engaged with the respective motor gears of the three or more induction motors.SELECTED DRAWING: Figure 1
【課題】モータギアとリングギアとの噛み合いが悪化するのを抑制することが可能なインホイールモータ型の車両駆動装置を提供する。【解決手段】車両駆動装置100は、車輪WのホイールW2に設けられ、ホイールに駆動力を伝達する駆動軸D1と、外歯12aが設けられたモータギア12を含み、車輪を駆動させるための駆動力を発生させる3個以上の誘導モータ1であって、駆動軸の周方向に沿うとともに、ホイールの内部空間Nに3個以上の誘導モータの少なくとも一部が配置された誘導モータと、3個以上の誘導モータのモータギアの各々に噛み合うことによって駆動されることにより、駆動軸を駆動させるリングギア50とを備え、リングギアは、駆動軸に対して駆動軸の径方向と軸方向とに移動可能なように、駆動軸側とは分割された別体の部材であり、3個以上の誘導モータのモータギアの各々に噛み合って駆動軸の径方向における位置が定まるように構成されている。【選択図】図1 |
