８５２０７号）。2. Description of the Related Art In a wheel motor with a reducer of this type,
In order to prevent the vehicle body, motor and speed reducer from interfering with each other when the wheel moves up and down or turns, it is necessary to make special arrangements for mounting the motor. A wheel motor configured to drive the wheel by arranging a machine and transmitting the rotation output of the motor to the wheel via the planetary gear reducer has already been proposed (for example, Japanese Patent Laid-Open No. Hei 10 (1999) -242242). 2-111419 and Japanese Patent Laid-Open No. 4-1

た。However, these conventional ones adopt the planetary gear reducer as the reducer,
The output shaft that transmits the rotation output of the electric motor to the wheel through the planetary gear reducer is divided in the axial direction of the wheel motor, and then the output is taken out by aligning the shaft centers, so the configuration is complicated and difficult to assemble. Further, since the supporting span of the output shaft has to be shortened, there is a problem that the supporting strength against the tilt of the wheel including the tire is low.

It is possible to provide a wheel motor capable of increasing the support strength for the rotor and reducing the diameter of the bearing that supports the rotor.

る。In order to achieve the above object, the present invention provides an electric motor and a gear reducer in an inner space portion of a wheel, and rotationally drives the wheel by a rotational output of the electric motor. In the configured wheel motor, the electric motor includes a stator fixed to a case side of the electric motor fixed to a vehicle body side, a rotor rotatably provided inside the stator, and a rotation of the rotor. An output shaft for transmitting an output to the wheel via the gear reducer, the output shaft being rotatably supported at both end portions of the case while penetrating a rotation center hole of the rotor. The rotor is configured to be supported by the output shaft via a bearing.

な支持強度を得ることが可能となる。The output shaft is rotatably supported at both ends of the case while penetrating the rotation center hole of the rotor. As a result, despite the fact that the electric motor and the gear reducer are arranged in the inner space of the wheel, the structure is simple and the assembly is easy, and the dimension of the wheel motor as a whole in the direction of the output shaft is short. Since the support span of the output shaft can be maximized, it is possible to obtain sufficient support strength against the collapse of the wheel including the tire.

上する。The rotor is supported by the output shaft via a bearing. As a result, the diameter of the bearing that supports the rotor can be made small, and since the rotor and the output shaft rotate in the same direction by further reducing the speed of the gear reducer by two stages, the bearing can support the relative rotational difference. Therefore, the wear resistance is also improved.
