Claim:
A toroidal transmission comprising four support brackets ( 16 a , 16 b , 16 c , 16 d ) supported so as to be pivotable about respective axes (X a , X b , X c , X d ), rollers (l 5 a - 15 d ) rotatably supported one on each of said support brackets ( 16 a , 16 b , 16 c , 16 d ) so as to be in rolling contact with toroidal disks for transmitting a driving torque therebetween, driver pulleys ( 21 a ) connected in a rotationally fixed manner to said support brackets ( 16 a , 16 b , 16 c , 16 d ) the driver pulleys ( 21 a ) being interconnected via drive means ( 24 , 25 , 26 ) wrapped around the driver pulleys ( 21 a ) for coupling the pivoting movement of the support brackets ( 16 a , 16 b , 16 c , 16 d ) about the respective axes (X a , X b , X c , X d ), two adjacent driver pulleys ( 21 a ) being connected to an adjacent one of the other driver pulleys ( 21 a ) by the drive means ( 24 , 25 , 26 ) so that all driver pulleys are interconnected for common pivoting of the support brackets ( 16 a , 16 b , 16 c , 16 d ), the driver pulleys ( 21 a ) having driver elements ( 22 , 23 ) being arranged axially adjacent to one another and being formed by a single component so that any bending torque applied to the support brackets ( 16 d , 16 b ) by the drive means ( 24 , 25 ) and respectively, ( 24 , 26 ) is minimized.
