Abstract (en)

[origin: WO9905433A1] The invention relates to an infinitely variable toroidal drive, comprising a housing (1), an input shaft (3), a torque shaft (34), two input discs (5, 15) with toroidal inner surfaces and two output discs (6, 16) with toroidal inner surfaces. One input disc and one output disc each form a pair and the two output discs are arranged next to each other and in mirror symmetry. The toroidal drive also comprises several friction wheels for transmitting a torque from the input disc to the corresponding output disc, an output shaft (10) and a gear wheel system (8, 9) between the output discs and the output shaft. A holding frame (2) is removably fastened to the drive housing (1), which frame consists of an upper frame clamp (28), a lower frame clamp (29), and a cup-shaped bearing support member (7). The lower frame clamp (29) has a recess (45) and one end of the output shaft (10) is mounted via a bearing (32) in a rotating manner.
