Title:

VEHICULAR STEPLESS SPEED CHANGE DEVICE

Document Type and Number:

Japanese Patent JP2016070479

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a vehicular stepless speed change device in which the stepless speed change is carried out under utilization of a planetary gear set and a stepless speed change mechanism, a starting device such as a torque-converter or the like can be removed, a range of speed change ratio can be expanded, and a fuel consumption and a power force performance can be improved.SOLUTION: A vehicular stepless speed change device includes: an input shaft to which a rotating power force of an engine is inputted; the first power force transmitting shaft arranged in parallel with the input shaft while being specifically spaced apart; a stepless speed change mechanism for changing a rotating speed of the input shaft and transmitting the changed rotating speed to the first power force transmitting shaft; the second power force transmitting shaft to which a rotating power force of the first power force transmitting shaft is selectively transmitted; the third power force transmitting shaft arranged to be spaced apart from the second power force transmitting shaft; a planetary gear set having the first, second and third rotating elements; an idling gear set for operatively connecting the input shaft with the first rotating element of the planetary gear set. The second rotating element is directly connected to the third power force transmitting shaft, and the third rotating element is directly connected to the second power force transmitting shaft.SELECTED DRAWING: Figure 1
