Patent ID: 7824294

Claim:
A transmission system for a vehicle, comprising: an input shaft connectable to a drive source; an output shaft connectable to wheels of the vehicle; a transmission that comprises at least one of a synchromesh and a dog clutch necessary for changing the transmission ratio, said transmission having an input and output shaft, the transmission ratio of which can have at least two values, wherein the input shaft of the transmission is connected to the input shaft of the transmission system via a first node and the output shaft of the transmission is connected to the output shaft of the transmission system via a second node; a reaction means comprising a brake, wherein a portion of the brake is connected to a fixed housing and wherein the brake can be appropriately activated such that more or less torque can be balanced; an epicyclic gearing having at least three rotational members, of which a first rotational member is connected to the first node, a second rotational member is connected to the second node so that the epicyclic gearing is parallel with the transmission, and a third rotational member is connectable to the reaction means via a third node; and wherein the brake is a friction brake which can dissipate enough power to halt the third rotational member.
