Abstract
Abstract Driving system containing at a minimum a first planetary coupling, equipped with a central wheel spindle, a planetary spindle and an annular ring spindle, a first driving component coupled to the central wheel spindle, a second driving component coupled to the planetary spindle, a continuously variable transmission with a primary axle and a secondary axle for the driving of a driving gear; and switchable couplings which on the one hand are connected to the planetary spindle and the annular ring spindle and on the other hand are connected to the fixed surroundings and the primary axle. By adjusting the switched states with the aid of the couplings, a large number of practical energy exchange paths, which can be increased in number by the fitting of a second planetary coupling furnished with a central wheel spindle coupled rigidly to the central wheel spindle of the first planetary coupling, and furnished with a planetary spindle coupled rigidly to the planetary spindle of the first planetary coupling, and switchable couplings which on the one hand are connected to the planetary spindle and the annular ring spindle of the second planetary coupling, and on the other hand are connected to a driving axle of the second driving component, can be attained.
