Japanese Patent JP2017219151
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transmission device of a vehicle capable of realizing a smooth shift operation with a simple constitution.SOLUTION: A transmission device 13 has a first clutch mechanism 30 for connecting and disconnecting a low-speed gear portion 21 and a motor 11, and a second clutch mechanism 40 for connecting and disconnecting a high-speed gear portion 22 and the motor 11. The transmission device 13 has a first actuator 33 for changing an operation state of the first clutch mechanism 30 according to a hydraulic pressure of a first operation chamber 33B, a first oil passage 35 communicated to the first operation chamber 33B, a second actuator 43 for changing an operation state of the second clutch mechanism 40 according to a hydraulic pressure of the second operation chamber 43B, and a second oil passage 45 communicated to the second operation chamber 43B. A volume of a first adjustment chamber 37 configuring a part of the first oil passage 35 and a volume of a second adjustment chamber 47 configuring a part of the second oil passage 45 are increased and decreased in a manner that when one of them is increased, the other is decreased, by operating a switch lever 53 connected to a partition wall 52B of a switch cylinder 52.SELECTED DRAWING: Figure 1
