However, in such a case, the oil pump is driven by a shaft that does not rotate at a slowed down rate, which is disadvantageous in terms of durability of the oil pump

Embodiment Construction

[0016] In the following description and drawings, the invention is described in more detail in exemplary embodiments.

[0017] FIG. 1 is a sectional view of a main structure of a wheel assembly having an in-wheel motor according to an exemplary embodiment of the present invention. In this figure, the tire and the upper 1 / 3 portion of the wheel are omitted.

[0018] The wheel assembly 10 includes a wheel 14 on which tires (not shown) are mounted. As will be described in detail below, the main part of the constituent elements related to the motor is accommodated in a space surrounded by the inner peripheral surface 14 a of the rim of the wheel 14 . In the following description, the term “inside of the wheel assembly” refers to a substantially cylindrical space surrounded by the rim inner peripheral surface 14 a of the wheel 14 . However, expressions such as "a component is arranged within the wheel assembly" do not always express that the entire component is completely accommo...

Abstract

A wheel assembly with an in-wheel motor, which transmits rotational output of an output shaft of a motor to a wheel via a counter gear, is provided with an oil pump that is driven by rotational output of the counter gear and an oil flow path that leads oil from the oil pump to the motor.

Description

technical field [0001] The present invention generally relates to wheel assemblies having in-wheel electric motors that transmit the rotational output of the electric motors to the wheels through counter gears. Background technique [0002] For example, Japanese Patent Application Publication No. JP-A-2005-335623 describes a related wheel assembly having an in-wheel motor that reduces (i.e., slows down or decelerates) the motor's rotational output, which is then transmission to the wheels. In such wheel assemblies with in-wheel motors, the oil pump is driven by a shaft rotating at a reduced rate. [0003] However, in the case of the invention of Japanese Patent Application Publication No. JP-A-2005-335623, a planetary gear set serving as a reduction mechanism is arranged concentrically with the electrodes and in series. Therefore, in the case of such a structure, it is easy to supply oil from the oil pump to the planetary gear set, but it is not easy to supply oil from the...
