  "textContent": "Infinitely variable change-speed gear (2) for all-wheel drive vehicles comprises a drive shaft consisting of a first and a second gear unit (9, 10). The first gear unit drives a front-wheel drive (28) and the second gear unit drives a rear-wheel drive (28'). The front-wheel drive and the rear-wheel drive are each formed by an output of a summation gear (25, 36). The summation gear has a first gear input (24, 26') kinematically coupled to the first or second gear unit, and a second gear input (31, 31') kinematically coupled to the drive shaft (18-20, 34, 34'). The transmissions of the first and second gear units are adjusted so that the resulting speed of the front-wheel drive and the rear-wheel drive is zero. Preferred Features: The infinitely variable change-speed gear is a toroidal drive and the first and the second gear units are each formed by a full toroidal drive unit.",
