Document Type and Number:
Japanese Patent JP2020085026
Kind Code:
A
Abstract:
To provide a drive transmission device for a vehicle which is high in a degree of freedom of the setting of a gear ratio, and can minimize dimensions in a radial direction and an axial direction.SOLUTION: A drive transmission device 100 for a vehicle comprises: a deceleration device 2; a differential gear device 3 arranged coaxial with the deceleration device 2, and distributing drive forces transmitted from the deceleration device 2 to a pair of wheels; a case 1 for accommodating the deceleration device 2 and the differential gear device 3: and a first bearing 63 for rotatably supporting the differential gear device 3 to the case 1. The deceleration device 2 includes a planetary gear mechanism 22 having a carrier C22, a pinion gear P22 and a pinion shaft A22. An inside diameter ID_63 of the first bearing 63 is larger than an outside diameter OD_A22 of a rotation trajectory of the pinion shaft A22. The first bearing 63 is arranged at a side of the differential groove device 3 in an axial direction L rather than the pinion gear P22.SELECTED DRAWING: Figure 3
