VEHICLE DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2018044577
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a cost of a planetary gear mechanism low in a vehicle driving device using a gear device which amplifies a torque difference and performs distribution by using a planetary gear mechanism.SOLUTION: A gear device 30 which distributes a torque to right and left races comprises planetary gear mechanism 30L, 30R having three elements and two degrees of freedom formed by combining two concentrically with right and left middle gears 13L, 13R, internal gears R, R, planetary carriers C, Cprovided concentrically with the internal gears R, R, sun gears S, Sprovided concentrically with the internal gear R, Rand a plurality of planetary gears P, Pare provided. A first binding member 31 which binds one side planetary carrier Cand the other side sun gear Sand a second binding member 32 which binds one side sun gear Sand the other side planetary carrier Care provided. The planetary gears P, Pare supported freely rotatably by a carrier pin 33 onto the planetary carriers C, Cand both ends of the carrier pin 33 are held between output side small diameter gears 13b of the middle gear shafts 13L, 13R and collars 40.SELECTED DRAWING: Figure 2
