Title:
VEHICLE POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015048935
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce a load applied on a journal part of an input shaft or an output shaft without increasing the number of bearings.SOLUTION: An input shaft 11 comprises first and second journal parts J1, J2 which are rotatably supported by two pieces of bearings 28, 29, the first journal part J1 is arranged between a second unit and a third unit, and the second journal part J2 is arranged between a fourth unit and a fifth unit. Therefore, even if a load is inputted into the input shaft 11 from any transmission units, a maximum distance between an input point of the load and the first and second journal parts J1, J2 can be shortened. By this constitution, the maximum bending moment applied to the input shaft 11a, a maximum warpage angle and a maximum warpage amount are reduced, the number of individuals of the bearings 28, 29 is suppressed to the minimum, thereby the friction of the bearings 28, 29 can be reduced, and the durability of the bearings can be improved while suppressing an increase of an axial dimension of the input shaft 11.
