Abstract
A system and method for controlling the endload force of a variator includes reducing a net force applied to a variator input disc of the variator. The variator includes an endload chamber, a subtraction chamber, and a valve fluidly coupled between the endload chamber and the subtraction chamber. Each of the endload chamber and the subtraction chamber applies an opposing force to the variator input disc. The valve is activateable to reduce the net force applied to the variator input disc. The valve may be activated based on the variator ratio, the position of the variator roller, and/or other parameters of the variator or operation thereof.
