  • Plate-link chain
    Patent number: 9797472
    Abstract: A plate-link chain for a continuously variable transmission of a motor vehicle. The chain includes relatively long and relatively short chain links. In long-short regions the chain links are arranged to overlap in a chain running direction by arranging plate-links disposed adjacent to one another transversely with respect to the chain running direction, and coupled to one another by pairs of rocker pressure members. In the long-short regions the plate-links of the chain links are arranged in a double configuration or in a triple configuration. Spacing or biasing elements are provided between pairs of side-by-side plate-links to provide damping of the plate-link chain when in operation.
