Title:
VEHICULAR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/057190
Kind Code:
A1
Abstract:
The present invention provides a vehicular drive device in which a sensor rotor is appropriately positioned when the sensor rotor is positioned more to a first side in the axial direction than the rotor of a machine generator. The present invention is provided with a machine generator (MG), a rotation sensor (18), and frictional couplers (CL1, CL2). The machine generator (MG) is provided with a rotor (Ro) and a rotor support member (30). The rotation sensor (18) is provided with a sensor rotor (97) and a sensor rotor support member (98). The rotor support member (30) is provided with a cylindrical part (31) and an extending part (35). The frictional couplers (CL1, CL2) are positioned radially inward (R1) relative to the inner circumferential surface of the cylindrical part (31) in a position that overlaps the cylindrical part (31) as viewed from the radial direction (R). The sensor rotor support member (98) is provided at a portion of the cylindrical part (31) than is further toward the first side (L1) in the axial direction than the rotor (Ro). The diameter at the inner circumferential surfaces of the sensor rotor (97) and the sensor rotor support member (98) at the smallest-diameter portion is greater than the diameter at the outer circumferential surfaces of the frictional couplers (CL1, CL2) at the largest-diameter portions.
