 Vehicular power transmission device patent thumbnailnew patent Vehicular power transmission device
A vehicular power transmission device including a crank type continuously variable transmission is provided in which when the vehicle transitions to the deceleration traveling state, a second one-way clutch (69) is engaged to thus transmit to an engine (e) the driving force that has been transmitted back via auxiliary driving force transmission method (54), thereby enabling engine braking to be operated. In this process, although a difference occurs in the time lag before the second one-way clutch (69) is engaged depending on the magnitude of the differential rotation, since the rotation of an input shaft (12) is braked or assisted by the driving force of an electric motor (24) of a shift actuator (23) changing the gear ratio of a continuously variable transmission (t) so that the time taken for the differential rotation to become zero coincides with the preset predetermined time, it is possible to make the time lag before engine braking operates uniform, thus eliminating any disagreeable sensation for a driver..
