ABSTRACT:
The device is so designed as to be cheap enough to be sold in large numbers and is particularly simple, compact and has a very low power consumption. It comprises a hydrokinetic converter and a gear mechanism having two forward speeds established by means of two pairs of pinions. It is completed by two clutches and a free-wheel disposed in the converter which provide the connection with the two input elements of the mechanism. These two clutches are actuated by a single slidable plate which moves as a function of parameters such as the speed of the vehicle or the load on the engine. The two clutches are disposed on opposite sides of the plate and one clutch is connected in parallel with the free-wheel.
