Title:
VEHICLE POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015206393
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the unexpected transmission of a drive force caused by the engagement of a clutch, in a vehicle power transmission device having the clutch which blocks power transmission between a drive source and a crank-type gear change mechanism.SOLUTION: When a change gear input shaft 11A causes fixation and is brought into a non-rotatable state, a clutch 52 is released in engagement, a drive source output shaft 11B is released from the change gear input shaft 11A, a drive force of a drive source E is transmitted to a change gear output shaft 12B from the drive source output shaft 11B via auxiliary power transmission means 29, and thereby a vehicle can retreat and travel up to a repair shop by the drive force of the drive source E. Clutch control means 60 which controls the engagement/engagement-release of the clutch 52 makes the clutch 52 transit to an engagement state from an engagement-release state on condition that a one-way clutch 21 of a crank-type gear change mechanism U is in the engagement-release state, and thus, it can be surely prevented that the drive force is unexpectedly transmitted to a drive wheel W simultaneously with the engagement of the clutch 52.
