Abstract:
An infinitely variable toroidal drive having:an input shaft (3) defining an axis of rotation; a torque shaft (20) coaxially disposed relative thereto; two input discs (5, 12) with toroidal shaped inner surfaces coaxial with said input shaft; two output discs (6, 11) with toroidal shaped inner surfaces coaxial with said input shaft, each input disc and an output disc forming a pair with both output discs being disposed with mirror symmetry adjacent each other, a contact-pressure device (4) for one of said input discs in order to apply pressure to the input discs in a direction toward said output discs, a universal bearing (18) is provided between the other of the input discs (5) and an axial flange (9) firmly connected with said input shaft (3), said bearing providing both axial and the radial support of said other input disc (5); and a gear wheel between said output discs; wherein said universal bearing (18) has balls which are guided between a recess (21) integrated in said other input disc (5) and a complementarily recess (22) in said axial flange (9).
