AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP3168184
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the occurrence of gear noise by providing an auxiliary input gear with an outer cylindrical part which meshes with a main output gear, an inner cylindrical part supported on a shaft, a connection part which connects both cylindrical parts, and providing a connection member which connects an internal gear and the inner cylindrical part mutually.
SOLUTION: An auxiliary input gear 202 has an outer cylindrical part 202B in which a tooth face which meshes with a main output gear 101 is formed, a hub part 202A, and a connection part 202C which connects both of the parts, a bearing 203 is provided in an inner peripheral part of the hub part 202A and is rotatably supported on an auxiliary output shaft 206, and a disk member 204 is press-fitted and fixed in an end part of the hub part 202A. Outer periphery of the disk member 204 is integrally connected with an internal gear 216R, and a pinion carrier 216PC which supports a pinion 216P which meshes with the internal gear 216R and a sun gear 216S is fitted in the auxiliary output shaft 206. In the auxiliary output shaft 206, rotation force is inputted from the carrier 216PC and is output from an auxiliary output gear 208 through an inner ring 209A of the bearing. Consequently, it is possible to prolong the length of twisting, reduce the twisting rigidity, and prevent the occurrence of noise.
