駆動力調整装置
Document Type and Number:
Japanese Patent JP6911652
Kind Code:
B2
Abstract:
A driving force adjustment apparatus includes: a differential apparatus (1) that interposes a differential gear (15) supported by a differential case (17) between a left shaft (12) and a right shaft (13) of driving wheels; a driving source (2) that drives the driving wheels; an adjusting motor (3) that adjusts a driving force difference between the left shaft (12) and the right shaft (13); a planetary gear mechanism (4) of three elements and two degree-of-freedom. The driving force adjustment apparatus further includes a driving shaft (5) that is coupled to a first element of the planetary gear mechanism (4) and that is coaxially arranged with the planetary gear mechanism (4); a first gear train (6) that adjusts a reduction ratio between a second element of the planetary gear mechanism (4) and one of the left shaft (12) and the right shaft (13) and that couples the second element to the one of the left shaft (12) and the right shaft (13); a second gear train (7) that adjusts a reduction ratio between the driving shaft (5) and the differential case (17) of the differential apparatus (1) and that couples the driving shaft (5) to the differential case (17); a third gear train (8) that adjusts a reduction ratio between the driving source (2) and the driving shaft (5) and that couples the driving source (2) to the driving shaft (5); and a fourth gear train (9) that adjusts a reduction ratio between a third element of the planetary gear mechanism (4) and the adjusting motor (3) and that couples the third element to the adjusting motor (3). This allows the driving force adjustment apparatus achieve both traveling function and driving force adjusting function with a simple configuration light in weight.
