Title:
Support structure of the axis of rotation of vehicles
Document Type and Number:
Japanese Patent JP6233324
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mechanism which can effectively reduce a tooth hammering sound and noise, in a support structure of a rotating shaft of a vehicle which includes a rotor shaft and a drive shaft of an electric motor.SOLUTION: Since at least a part of a cross section of an accommodation groove 80 is inclined to a second rotating axial core C2, inclined faces 80a, 80b are formed at the accommodation groove 80, and an elastic member 72 is accommodated in a state of tightly adhering to the inclined faces 80a, 80b. By this constitution, when thrust forces acting in a thrust direction (axial direction) are transmitted to a second rotor shaft 28 and a reduction shaft 26, the thrust forces act on the inclined faces 80a, 80b, the elastic member 72 is elastically deformed, a collision force is decreased, and noise is reduced.SELECTED DRAWING: Figure 2
