ABSTRACT:
A variable ratio chain-belt transmission for use in a vehicle, includes a pair of variable ratio pulleys having a plurality of pins which are lined in a plurality of circles, a chain-belt engaging with both variable ratio pulleys. Different sized pulleys are formed by pushing and pulling the pins in and out of engagement with the chain-belt by activating various solenoids, whereby various pulley ratios are formed when the plurality of pins form different relative sized pulleys. A clutch mechanism for use with the variable ratio chain-belt transmission includes distinct forward and reverse clutch assemblies.
