Abstract
A continually variable cone-pulley, belt-drive transmission includes a primary shaft having a cone-pulley arrangement actuated by a pressure servo, a secondary shaft driven by an endless belt having a cone-pulley, actuated by a second pressure servo. Spring assemblies located in the pressure servo preload compression springs. Each spring assembly includes a compression spring located in spring-receiving rings, a cup-shaped support ring, and a guide ring comprising a peg-shaped spring guide. Preload on the compression springs is released during the first complete movement of the cone-pulley assembly by loading a locking and unlocking pin.
