<p>A motive unit (1) particularly, but not exclusively, for motor vehicles, which has an advantage in that the motor vehicle can be started from a standstill with gears in constant mesh and using no friction clutch, comprises, mounted in a framework (2), a rotary internal combustion engine (3) having a cylinder-carrying rotor (9) and a crankshaft (10), counter-rotating relative to each other, a differential system (4) wherein a spider (41) is rotatively rigid with the crankshaft (10) and carries two interlinked planet gears (43, 44), the one (43) enmeshed with an action side gear (45) rotatively rigid with the rotor (9) and the other (44) enmeshed with a reaction side gear (46) carried rotatably on the framework (2), and a one-way drive (5) extending between the rotor (9) and the reaction side gear (46) to allow of reverse rotation at a predetermined angular velocity (C) of the reaction side gear (46).</p> |
