Abstract: Transmission chain for a cone pulley transmission with links, coupled by pins, engaging the cone pulley surfaces, and by elongate each link accommodating, non-rotatable with respect to it, a pin and, in the longitudinal dimension of the link at a distance therefrom an interpiece; each pin cooperating with an opposite interpiece and with; in each link, adjacent each active side surface of a pin and an interpiece respectively sufficient free space to accommodate an interpiece or pin respectively, which is coupled to an adjacent link, during its movement, and with adjacent sets of links mutually coupled in the longitudinal direction of the transmission chain in that one pin in a first link co-operates with a rolling contact movement with an interpiece in an adjacent, staggered link.

Abstract: Friction transmission with opposite-pulley sheaves and transverse elements mating therewith, having an asymmetry relative to the longitudinal center plane thereof.

Abstract: Transmission chain for a cone pulley drive with intercoupled links and pivot pins inserted through link openings, the end surfaces of which cooperate with the cone surfaces, and where between each pivot pin, on the one hand, and the opposite-lying upright opening sides of a number of adjacent links, on the other, an intermediate piece with rolling contact action is inserted whose first longitudinal side is coupled to the link opening side and of which the opposite-lying second longitudinal surface forms the rolling contact surface cooperates with the longitudinal side of the pin, a number of grooves running between the first and the second longitudinal side being formed in each intermediate piece in at least the narrow longitudinal side facing the inside of the chain.

Abstract: Device for determining the torque transmitted between a set of conical disks of a continuously variable transmission and the shaft thereof comprising an interconnecting element which is twistable over a restricted angle and interconnected between the set of conical disks on the one hand and the shaft on the other hand, and by two toothrings with radially outwardly directed teeth, coaxial with this element and connected to the respective ends thereof. Each tooth ring is enclosed by a complementary U-shaped stationary toothring provided with a winding the turns of which run in the circumferential direction.

Abstract: A transmission chain comprising links and hinge pins extending through link apertures an intermediate member being received between each hinge pin and the opposite aperture sides of a plurality of adjacent links, the length of the intermediate member being equal to or somewhat less than the length of the hinge pin a limited displacement thereof in the longitudinal direction being possible.
