  • Transmission system and method for driving a vehicle
    Patent number: 7410436
    Abstract: A vehicle (1) has an epicyclic gearing (3) with three rotational members (5, 7, 9). Rotational member (9) is connected to a load formed by the wheels (17) of a vehicle. Rotational member (5) is connected to a flywheel (11) and rotational member (7) is connected to an engine (13). The vehicle (1) furthermore comprises a transmission-unit (19), embodied either as a conventional or as a automated manual transmission-unit, with two in/outputs (21, 23). In/output (21) is connected to the rotational member (7) and in/output (23) is connected to the third rotational member (9). A force-closed clutch (25) with slip capacity is located between in/output (21) and rotational member (7). With this transmission-system, the wheels (17) remain driven by the engine (13), also during disengagement of the clutch (25).

  • Transmission system, especially for a motor vehicle
    Patent number: 6488605
    Abstract: The present invention relates to a transmission system, especially for use in a motorized vehicle. More particularly, the present invention discloses the use of a flywheel for assisting an engine in speeding up when acceleration is requested. The flywheel (135) is coupled to an epicyclic gearing (G) having three rotational members (41, 42, 43); this epicyclic gearing (G) is further coupled to a load (L) and to an engine (E), in parallel to a transmission unit (MT; CVT).
