POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/194633
Kind Code:
A1
Abstract:
 The auxiliary power transmission unit (80) of a power transmission device (1) is provided with an auxiliary one-way clutch (82) and a connecting/disconnecting clutch (83). The connecting/disconnecting clutch (83) is set in a connected state during a first state in which the first transmission ratio (MR) of a main power transmission unit (79) is greater than the second transmission ratio (AR) of the auxiliary power transmission unit (80), and the connecting/disconnecting clutch (83) is set in a disconnected state during a second state in which the first transmission ratio (MR) is less than the second transmission ratio (AR). The connecting/disconnecting clutch (83) is temporarily set in a disconnected state when, during the first state, the difference in rotational speed between the two sides of the auxiliary one-way clutch (82) converges to zero.
