Abstract
In an infinitely variable transmission wherein two toric traction discs are rotatably supported opposite one another so as to define therebetween a toric cavity in which at least two motion transmitting traction rollers are disposed in engagement with the toric discs and supported by pivot trunnions, means are provided for controllably pivoting the trunnions about a control axis which is essentially tangential to the center circle of the toric cavity and wherein the pivot trunnions have support rollers supported on partial circular track structures with end sections extending inwardly from the circular track structure so as to apply increased engagement forces to the traction rollers in the pivotal end positions of the trunnions while at the same time limiting their pivotal movement.
