  • Patent number: 8641566
    Abstract: A toothed plate for a toothed-plate plate-link chain, wherein the toothed plate includes two teeth, each having an inner flank, and an indentation between the teeth. The indentation includes a transition between a tooth flank and a curved innermost region. The transition has a convex curvature and is positioned at a junction of one of the inner flanks and the innermost region.

  • Patent number: 8192314
    Abstract: A plate for a rocker joint chain, wherein the plate includes two longitudinal legs and two vertical legs that together surround a plate opening. The plate includes an indentation positioned on an outer edge of at least one of the longitudinal legs, and it includes at least one tab positioned on the outside contour of the plate. The plate configuration enables an easier determination to be made to ascertain a specified orientation of such plates within an assembled plate-link chain formed from a plurality of plates.

  • Patent number: 8052561
    Abstract: A method for optimizing the link plates of a plate-link chain drive chain for use in a variable speed unit of a belt-driven conical-pulley transmission. The chain includes plate links formed from pairs of plates that have openings through which pairs of rocker members extend. The plates include longitudinally-extending legs that extend in the chain movement direction and vertical legs that extend perpendicular to the chain movement direction. The method is directed to minimizing bending stresses in the longitudinal and vertical legs of the plates as the chain passes around a pulley, and as the rocker members and the chain tension impose forces on the plates. The stress minimization results in minimal material usage and minimal weight of the chain.

  • Publication number: 20050209035
    Abstract: In given marginal conditions relating to force to be transmitted, division etc, the material requirements for the plates (10) of a plate link chain of a variator are minimised by shaping the plate in such a way that the active bending moment in the longitudinal limbs (18) which are parallel to the moving direction of the plate link chain and/or the transversal limbs (20) which are perpendicular to the moving direction of the plate link chain is minimal.

  • Patent number: 6346058
    Abstract: A flexible torque-transmitting device (1) such as a chain belt that runs in an endless loop around a first and second pair of conical disks in a continuously variable transmission of a motor vehicle includes means to keep the transverse force-transfer elements (2a, 2b) from becoming dislodged out of their seating positions in the lengthwise-running links (3a, 3b, 3c) of the chain belt.
