Abstract

The invention relates to a gearbox which includes an input shaft (2) connected to the engine, an output shaft (3) connected to the wheels of the vehicle or a flywheel mass, and a series of gears for transmitting the rotation of the input shaft (2) to the output shaft (3). The invention is characterised in that the gearbox includes an impeller module (4) rotatably secured to the input shaft (2) and a reducer module (6) rotatably secured to the output shaft (3), said reducer module (6) rotating in the same direction as or the opposite direction to the impeller module (4) and said reducer module (6) rotating by means of inertia when the rotation of the input shaft (2) is slowing down.

IPC Classes  ?

• F16H 3/74 - Complexes, not using actuatable speed-changing or regulating members, e.g. with gear ratio determined by free play of frictional or other forces
• F16H 33/14 - Gearings for conveying rotary motion with variable velocity ratio, in which self-regulation is sought based essentially on inertia having orbital members influenced by regulating masses
• F16H 37/08 - Combinations of mechanical gearings, not provided for in groups comprising essentially only toothed or friction gearings with a plurality of driving or driven shaftsCombinations of mechanical gearings, not provided for in groups comprising essentially only toothed or friction gearings with arrangements for dividing torque between two or more intermediate shafts with differential gearing
