ABSTRACT:
A continuously variable transmission has an input pulley assembly connected to a first transfer pulley assembly with a first chain and a second transfer pulley assembly connected to an output pulley assembly with a second chain. The first transfer pulley assembly and the second transfer pulley assembly shaft a common shuttle disk that moves axially on a countershaft that carries the first and second transfer pulleys. The input pulley assembly and the output pulley assembly are generally axially aligned and a bearing carrier is positioned between the pulleys. A high pressure fluid supply system reduces or eliminates axial loading on the shafts of the transmission.
