Title:
VEHICLE POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2014173710
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To quickly finish the warming of a vehicle power transmission device having a crank type continuously variable transmission.SOLUTION: Since a plurality of partitioning walls 11f for partitioning a plurality of transmission units 14 are formed in a transmission case 11, the generation of film face vibration is suppressed by enhancing the rigidity of the transmission case 11 by the partitioning walls 11f, and noise can be reduced to the minimum by suppressing an increase of weight. Furthermore, since a gutter member 43 axially extending across a plurality of the partitioning walls 11f is arranged in the transmission case 11, and oil supplied to one end of the gutter member 43 from the inside of an actuator case 42 is distributed in a plurality of spaces between a plurality of the partitioning walls 11f from the gutter member 43, the warming of a vehicle power transmission device can be finished in a short time by warming the inside of the transmission case 11, by high-temperature oil, which is difficult to be raised in temperature compared with the inside of the actuator case 42 which accommodates an electric motor 24 being a heat generation member.
