Abstract

This vehicle drive device satisfactorily maintains the support accuracy of a rotor of a rotating electric machine while reducing the size of the overall device. A vehicle drive device (D) is provided with a rotating electric machine (MG), which has a rotor (Ro) and a stator (St), as a drive power source of a wheel. The vehicle drive device (D) includes: a rotation sensor (23) that detects the rotation position of the rotor (Ro) with respect to the stator (St); a rotor support member (30) that supports the rotor (Ro) radially inward of the stator (St); an oil pump (OP) that comprises a pump rotor (21) arranged coaxial to the rotating electric machine (MG) and drive-coupled to the rotor support member (30), and a pump case (13) that accommodates the pump rotor (21); and a support bearing (62) that is arranged between the pump case (13) and the rotor support member in the radial direction (30), and rotatably supports the rotor support member (30) with respect to the pump case (13). The rotation sensor (23) and the support bearing (62) are arranged at overlapping positions as viewed from the radial direction.

Description

technical field [0001] The present invention relates to a vehicle drive device including a rotating electric machine having a rotor and a stator as a drive source of wheels. Background technique [0002] As a drive device for a vehicle as described above, for example, a device described in Patent Document 1 below is known. Hereinafter, in the description of the background art column, one or both of component names and reference signs in Patent Document 1 will be cited within parentheses for description. As in Patent Document 1 figure 2 As shown, the vehicle drive device includes: a rotation sensor for detecting the rotational position of the rotor (21) of the rotating electric machine (electric motor 20) relative to the stator (22), a rotor supporting member (rotor shaft 32) for supporting the rotor, and a An oil pump of a pump casing and a pump rotor accommodated in the pump casing. [0003] In this device, the rotor support member is fixed to the outer peripheral surfac...
