DRIVE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/095821
Kind Code:
A1
Abstract:
A carrier (CR) rotatably supports a first pinion gear (PG1) and a second pinion gear (PG2) that rotate together with one other. One of the carrier (CR) and a ring gear (RG) is coupled with a first gear (32) so as to rotate together therewith. A second gear (33) meshes with the first gear (32). The first gear (32) and the second gear (33) are each a double helical gear having a pair of teeth sections with mutually opposite handedness. The first pinion gear (PG1) and the second pinion gear (PG2) are each a helical gear. The handedness of the teeth sections of the first pinion gear (PG1) and the second pinion gear (PG2) are set such that the thrust load that the first pinion gear (PG1) receives from a sun gear (SG) and the thrust load that the second pinion gear (PG2) receives from the ring gear (RG) are opposite to one other.
