Title:
VEHICLE DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/068334
Kind Code:
A1
Abstract:
A first rotating element (E1) is a first sun gear (SG1) that rotates integrally with a rotor (12), a third rotating element (E3) is a first ring gear (RG1) that is coupled to a case (9), a fourth rotating element (E4) is a second ring gear (RG2) that rotates integrally with an input element (Ei), and a second rotating element (E2) is a first carrier (CR1) that rotatably supports a first pinion gear (PG1) and a second pinion gear (PG2) which rotate integrally with one another, wherein: the first pinion gear (PG1) meshes with the first sun gear (SG1) and the first ring gear (RG1); the second pinion gear (PG2) has a smaller diameter than the first pinion gear (PG1) and meshes with the second ring gear (RG2); the first sun gear (SG1) is supported in a radial direction (R) with respect to the case (9) by means of a first support bearing (B1); and the second ring gear (RG2) and the input element (Ei) are coupled such that relative displacement in the radial direction (R) is restricted.
