Variator and variator arrangement

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, and with at least two rollers which are arranged in the toroidal space for torque transfer between the driving disk and the driven disk, the rollers being in each case mounted rotatably on a roller carrier, the roller carriers being in each case spatially adjustable by means of a piston/cylinder arrangement, in order to adjust the transfer ratio of the variator, and the pistons of the piston/cylinder arrangements being in each case adjustable along a stroke axis, wherein the piston/cylinder arrangements are connected to the roller carriers via respective levers, wherein the roller carriers in each case are connected to the associated lever by means of a ball joint, and wherein the levers are mounted pivotally on a common system carrier.

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