Abstract

The invention relates to a cooling device for a continuously variable transmission, in particular to a cooling device for a self-suction continuously variable transmission. A pulley drive shaft oil channel is opened in the drive shaft along the axial direction, and at least one of the pulley fixed plate and the pulley moving plate is provided with an oil hole penetrating from the inside to the outside, and the oil hole communicates with the pulley drive shaft oil channel. The continuously variable transmission cooling device has the advantages of simple structure, low cost and high cooling efficiency.

Description

technical field [0001] The invention relates to a cooling device for a continuously variable transmission, in particular to a cooling device for a self-suction type continuously variable transmission. Background technique [0002] Continuously variable transmission can carry out stepless transmission within a certain speed ratio range, it can improve the fuel economy and driving comfort of the car, and is widely installed on cars. In a continuously variable transmission, the driving pulley drives the transmission belt, and the transmission belt drives the driven pulley. The transmission belt is usually made of metal, which will generate a lot of heat during operation, so it is necessary to dissipate heat from the transmission belt and the driving and driven pulleys. [0003] The utility model patent with the application number 201220173107.2 "a heat dissipation mechanism for a continuously variable transmission" dissipates heat from the transmission by setting a number of i...
