A CVT transmission for motor vehicles, in particular for agricultural tractors.

摘要

A CVT transmission (100) for agricultural tractors which provides equipment (15) for continuous variation of the motion by means of an epicyclic gear train (23). In the CVT transmission (100) the input of the motion from an engine (M) occurs in a direction substantially parallel to an axis (X) of longitudinal symmetry of the tractor, whilst the axes (a) and (b), of a shaft (10) and a shaft (18), respectively, between which the variation of the transmission ratio is effected, are transverse with respect to the axis (X) of longitudinal symmetry of the tractor. <IMAGE>
