Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217280
Kind Code:
A1
Abstract:
According to the present invention, a first rotating shaft (22) and a second rotating shaft (43) are connected by the engagement of a first pawl part (38) of a piston (32) and a second pawl part (47) of the second rotating shaft (43) on the basis of the supply of hydraulic oil to an oil chamber (37), and are thus connected in a state of being capable of transmitting rotation. When engaging with the second pawl part (47) of the second rotating shaft (43) on the basis of the supply of hydraulic fluid to the oil chamber (37), the first pawl part (38) of the piston (32) engages with a third pawl part (52) of a synchronizer ring (51) before the engagement with the second pawl part (47). The engagement surfaces of the first pawl part (38) and the second pawl part (47) are formed in inclined surfaces so that a force is applied to the first pawl part (38) and the second pawl part (47) in the direction for moving away from each other in the axial direction while the rotation is transmitted between the first rotating shaft (22) and the second rotating shaft (43).
