ABSTRACT:
A variable V-belt type continuously variable transmission for vehicles which includes an input shaft and an output shaft, a first torque transmitting gear mechanism alternatively connectable with the input shaft and the output shaft, a countershaft connected to the first torque transmitting gear mechanism, a variable V-belt and pulley assembly, one end of which is connected to the countershaft, and a second torque transmitting gear mechanism connected to an opposite end of the variable V-belt and pulley assembly and alternatively connectable with the input shaft and the output shaft such that torque transmission from the input shaft to the output shaft occurs via a first route through the first torque transmitting gear mechanism, the countershaft, the variable V-belt and pulley assembly and the second torque transmitting gear mechanism and via a second route through the second torque transmitting gear mechanism, the variable V-belt and pulley assembly, the countershaft and the first torque transmitting gear mechanism. As an alternative, a gear mechanism can be used to substitute for the clutch members.
