Abstract
In an infinitely variable transmission equipped with a V-shaped pulley having a stationary pulley element and a movable pulley element fitted on a shaft, and an endless belt engaged between the pulley elements, a movable pulley element pinch force control device includes a plurality of through bores formed through the peripheral wall of the shaft in axially spaced relation, and a slider axially slidably received within a hydraulic fluid introducing passage in the shaft and urged by the fluid pressure in a direction of closing the through bores. The movable pulley element is urged by the fluid pressure in a direction of closing the through bores, and by the force of the belt in a direction of closing the through bores, whereby the total opening area of the through bores is automatically varied in response to changes in the positions of the slider and the movable pulley element, to control the pinch force of the movable pulley element in a stepwise manner.
