Embodiment Construction

[0017] In the following description and in the drawings, the invention will be described in more detail by way of exemplary embodiments. 1 is a sectional view of a main structure of a wheel assembly with an in-wheel motor according to an exemplary embodiment of the present invention. In this figure, the tire of the wheel and about 1 / 3 of the upper part are omitted.

[0018] The tire / wheel assembly 10 includes a wheel 14 to which a tire, not shown, is mounted. As will be described in detail later, main parts of constituent elements related to the motor are housed in a space surrounded by the rim inner peripheral surface 14 a of the wheel 14 . In the following description, the expression “inside the tire / wheel assembly” means in a substantially cylindrical space surrounded by the rim inner peripheral surface 14 a of the wheel 14 . However, an expression such as "the component is arranged inside the tire / wheel assembly" does not always mean that the entire component is complete...

Abstract

A motor has a stator core, a coil, a rotor, and a motor case in which the stator core, the coil, and the rotor are housed. The motor is also provided with a fluid carrying member that is arranged around a coil end of the coil in the motor case and has an inlet hole that is communicated with a fluid supply source and a distribution hole that is communicated with a space inside the motor case.

Description

technical field [0001] The present invention relates to an in-wheel electric motor and a wheel assembly having the same. Background technique [0002] For example, Japanese Patent Application Publication No. JP-A-2005-73364 describes a related wheel assembly with an in-wheel electric motor, which includes: an electric motor; a rotating shaft that rotates according to the output torque of the electric motor; an oil pump that is set at one end of the rotary shaft; and an oil passage that supplies oil from an oil pump to the outer periphery of a stator core of the motor. In this wheel assembly with an in-wheel electric motor, oil from an oil pump is supplied into the electric motor from the outer periphery of the stator core of the electric motor via an oil passage having an open end in the upper portion of the electric motor case. The oil supplied in this way is used to cool the stator core and the stator coil, and then used to lubricate the bearings and reduction gears suppo...
