Patent ID: 6863637

Claim:
A wall mounting structure for a dual cavity toroidal continuously variable transmission, the dual cavity toroidal continuously variable transmission including two toroidal speed change units each including a pair of input and output disks rotatable about a common rotation axis, the input disks being axially spaced from each other, the output disks being disposed between the input disks and axially opposed to each other in a spaced relation, and a gear set drivingly connected with the output disks, the structure comprising: a transmission case adapted to accommodate the two toroidal speed change units; an intermediate wall adapted to be disposed between the output disks and accommodate the gear set; and a fastener fixing said intermediate wall to said transmission case and extending in a direction perpendicular to the rotation axis of the output disks, wherein said transmission case comprises side walls spaced from each other in a lateral direction perpendicular to the direction of the rotation axis of the output disks, said intermediate wall being fixed to the side walls by said fastener, and wherein said intermediate wall comprises flanges on opposed sides thereof in said lateral direction, said flanges each having a first contact surface extending in the direction of the rotation axis of the output disks, said side walls of said transmission case comprising shoulder portions each having a second contact surface contacted with said first contact surface, said fastener extending across the first and second contact surfaces to fix said flanges to said shoulder portions.
