DRIVING FORCE DISTRIBUTION/TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To improve reliability by smoothly lubricating sliding portion by preventing a deviation of lubricating oil even at the time of swivel travelling or the like.

SOLUTION: The driving force distribution/transmission device 1 has a gear input rotation member 53 and a gear output rotation member 55 that are operatively connected with each other so that they can transmit driving force through meshing between a drive pinion gear 91 and a ring gear 93 and also has a left and right pair of clutch output adjustment mechanisms 57, 59 joined to both ends of the gear output rotation member 55 and performing driving force output adjustment by engagement of main clutches 139. The drive pinion gear 91 and the ring gear 93 are received in a gear chamber 56 sectioned in a sealed manner. The main clutches 139 are respectively housed in a left and right pair of clutch chamber 125 sectioned in a sealed manner. Gear oil and clutch oil are respectively sealed in the gear chamber 56 and in lubrication spaces of three independent chambers of the left and right pair of clutch chambers 125.
