ABSTRACT:
A variator for a toroidal transmission, with a driving disk and with a driven disk, between which is set up a toroidal space which defines a toroidal reference circle. The variator, further, comprises at least two rollers which are arranged in the toroidal space for torque transfer between the driving disk and the driven disk. The rollers are in each case mounted rotatably on a roller carrier. The roller carriers are in each case spatially adjustable by means of a piston/cylinder arrangement, in order to adjust the transfer ratio of the variator. The pistons of the piston/cylinder arrangements are in each case adjustable along a stroke axis. Also, the pistons are connected to the roller carriers via respective levers.
