Abstract
To balance twisting torques acting on transmission chain pressure elements (11) located in an asymmetrical wedge zone between a friction disk (7,8) which has an essentially radially directed, plane face and a disk having a divergent, essentially conical engagement surface (14), the centers of curvature (17,18) of the friction surfaces (15,16) of the engagement elements are so positioned that the product of the engagement force components (20,21) acting parallel to the axes of rotation of the disks, and the radial spacing (a) of the contact points (19',23') at which the force components act is essentially equal to the product of the radially directed component (24) of the pulling force of the chain, when in operation, and the spacing (b') measured in a direction parallel to the respective shaft, of the contact point (23') of the pressure element with the disk having the substantially conical divergent engagement surface (14) from the center (C) of the pressure element, measured in its length direction. Any twisting moment tending to act on the pressure elements are thereby counter-balanced.
