Abstract
A control unit for an infinitely-variable-ratio transmission. The transmission includes a cylinder and a piston with a proximal and a distal end. A support stem is connected to the piston. The piston is hollow and has a head portion for interaction with an associated actuation fluid. A proximal portion extends away from the head portion. The support stem is connected to the proximal portion by an articulated joint and extends from the joint to the head portion to exit from the distal end of the piston.
Claims16
A control unit for an infinitely-variable-ratio transmission comprising a cylinder located in the infinitely-variable-ratio transmission, a piston having a proximal end and a distal end, and a support stem connected to said piston, said piston being hollow and having a head portion for interaction with associated actuation fluid, said head portion having a proximal end face which defines a chamber within the cylinder and is exposed to actuation fluid in the chamber, such that actuation fluid pressure within the chamber tends to cause said piston to move, and a proximal portion extending away from said proximal end face of said head portion, said support stem being connected to said proximal portion of said piston by an articulated joint and extending from said joint through said head portion to exit from said distal end of said piston.
