Abstract: A wheel driving device is proposed in which it is possible to prevent vibration of an internal gear due to torque transmitted to the internal gear from being transmitted to a speed reducer casing. The wheel driving device includes a speed reducer for transmitting the rotation of an electric motor to a hub ring supporting a vehicle wheel after reducing its speed. The speed reducer is a cycloid speed reducer including an external gear, and an internal gear meshing with the external gear and rotationally fixed to the speed reducer casing through a rotationally fixing arrangement which is also capable of elastically supporting the internal gear. The rotationally fixing arrangement absorbs, by elastic deformation, vibration of the internal gear due to torque transmitted from the external gear to the internal gear, thereby preventing the vibration of the internal gear from being transmitted to the speed reducer casing.

Abstract: A gear shaft of an output gear in a speed reducer of an in-wheel motor driving device is supported at a first end thereof and a second end thereof with respect to a housing. The gear shaft of the output gear is formed with a spline hole. The spline hole provides a spline-connection with an output shaft of a wheel hub.

Abstract: An object of the invention is to always maintain an outer pin holder and a housing in a speed reducer section at their predetermined positions, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, etc., and to eliminate rattling noise caused by the housing and the outer pin holder. A casing immobilizing member which is fixed to an inner surface of a speed reducer section casing and a housing immobilizing member which is fixed to an outer surface of a speed reducer section housing are provided between the speed reducer section casing and the speed reducer section housing. The casing immobilizing member and the housing immobilizing member are bonded with each other via a rubber member.

Abstract: A gear shaft of an output gear in a speed reducer B of an in-wheel motor driving device is supported at its two ends with respect to a housing. The double-end supported gear shaft of the output gear is formed with a spline hole. The spline hole provides spline-connection with an output shaft of the wheel hub C. This structure makes the gear shaft less likely to come out of alignment even if the output gear comes under a bending moment. Therefore, even if an external force such as a lateral force from a tire causes the output shaft of the wheel hub C to develop a shaft deflection, the deformation/displacement is absorbed by a gap between splines which connect the output shaft of the wheel hub C and the output gear with each other.
