Abstract

The toroidal drive has an input shaft (3) and a torque shaft (20) positioned coaxially thereto as well as two input discs (5, 12) and two output discs (6, 11) associated in pairs to the input discs. Between one of the input discs (5) and an axial flange (9), which is firmly connected with the input shaft (3) and upon which supports itself the input disc (5) is not pressurized by a contact-pressure device (4), one universal bearing (18) is provided which assumes both the axial support and the radial support of said input disc (5).
