Abstract

The invention relates to a belt type continuously variable transmission, which is used for changing the rotation speed in a transmission system and can be applied to speed change mechanisms such as automobiles and wind driven generators. The belt type continuously variable transmission has a simple structure and is skillful in design, the stress situation of a belt pulley and a shaft system can be improved, an axial advancing mechanism and a control system are simplified, and axial movement of half cone pulleys of driving and driven belt pulleys can be synchronously realized through only one axial advancing mechanism.

Description

technical field [0001] The invention relates to a belt-type continuously variable transmission, which is used to change the rotating speed in the transmission system, and can be applied to the transmission mechanisms of automobiles and wind power generators. Background technique [0002] The belt type continuously variable transmission is a kind of pulley transmission mechanism. By axially moving the movable semi-conical pulley of the main and driven pulleys, the speed change belt (belt or metal belt) moves along the V-shaped groove formed by the two cone pulleys. Radial sliding can continuously change the pitch circle radius of the driving and driven wheels to realize stepless speed change. The ratio of the pitch circle radius of the driving and driven wheels is the transmission speed ratio. In the existing belt-type continuously variable transmission, the axial movement of the movable semi-cone wheels of the driving and driven pulleys is realized by two axial propulsion me...
