段変速機における冷却装置。 Fixed sheave 31 fixed to drive shaft 2 and drive shaft 2
A driving pulley 3 consisting of a movable sheave 32 provided so as to be movable in the axial direction relative to the driven shaft 4, and a driven pulley consisting of a fixed sheave 51 fixed to the driven shaft 4 and a movable sheave 52 provided movable in the axial direction relative to the driven shaft 4. 5, and a belt 6 spanning between these pulleys 3 and 5.
This is a cooling device for a belt-type continuously variable transmission which is housed in a housing 1, and an outside air introduction passage 7 whose one end communicates with the outside of the housing 1 is formed in at least one of the drive shaft 2 and the driven shaft 4. The introduction passage 7 is opened 7a between the two sheaves 31, 32, 51, 52 of the pulleys 3, 5 on the shaft side forming the passage 7, and the two sheaves 31, 32,
The introduction passage 7 is located at the center in the radial direction between 51 and 52.
A cooling device for a belt-type continuously variable transmission, characterized in that it is provided with a blower fan 8 that blows outside air supplied through the belt radially outward.
