発明の名称 (英語) In-wheel motor for electric automobiles
発明の概要(英語) The present invention provides an in-wheel motor for an electric vehicle allowing a drive motor to be freely mounted onto a chassis irrespective of the shape, structure, and characteristics of the drive motor as well as allowing free selection of a reduction gear ratio without need to replace a drive motor.An in-wheel motor for an electric vehicle includes a drive motor (1200), a reduction gear mechanism (1300), a wheel bearing, and a mechanical brake and serves as a drive apparatus for an electric vehicle. The drive motor (1200) includes a casing (1210) which houses a rotor (1240) and a stator (1220); the reduction gear mechanism (1300) is implemented by a planetary gear mechanism; a wheel bearing is fixedly attached to the outer circumference of an end portion of a housing (1411), which houses a wheel shaft (1410) coupled to an output element of the planetary gear mechanism; mounting blocks (800, 810) having engagement means are provided respectively at upper and lower outside portions of the casing (1210); and attachments are attached to the corresponding mounting blocks (800, 810) and joined to corresponding joint mechanisms (612, 712), which are movably coupled to a suspension mechanism.
