A plate link chain includes a chain running direction, an axial direction, a radial direction, a plate link, and a rocker pin pair. Each rocker pin has a plate link side contact surface, a rolling surface, and axially opposite end faces. The end faces are inclined axially inwards from radially outside to radially inside, aligned transversely to the axial direction, and arranged for force transmitting contact with a conical pulley pair. The end faces have respective curvatures having a first curvature portion defined by a radial radius about a first axis parallel to the chain running direction, and a second curvature portion defined by an azimuthal radius about a second axis parallel to the radial direction. A magnitude of the radial radius increases from radially outside to radially central, or a magnitude of the azimuthal radius increases from forward to central with respect to the chain running direction.

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.

A chain belt for a continuously variable transmission which has a plurality of links and a plurality of coupling members connecting the plurality of links together. Each of the coupling members has an outer perimeter, a first end with a first prepared surface, and a second end with a second prepared surface. The prepared surfaces extend a depth from the outer perimeter of the coupling member. A first retaining member is fastened to the first prepared surface of the coupling members and a second retaining member is fastened to the second prepared surface of the coupling members. The first and second retaining members retain the plurality of links on the coupling members.

A continuously variable transmission (CVT) includes a power transmission mechanism and at least one conical disk. The power transmission mechanism has a contact surface, and the power transmission mechanism includes a plurality of engaging elements. The plurality of engaging elements are retractably disposed on the contact surface. The disk surface of the conical disk has a plurality of engaging walls capable of engaging with the engaging elements. The continuously variable transmission is able to transmit power by way of engagement, such that the coupling between the power transmission mechanism and the conical disk is more stable. Thus, the continuously variable transmission is adaptable to high torsion application.

A plate link chain for a continuously variable cone pulley transmission is disclosed. The plate link chain includes a first chain link, a second chain link, and a third chain link having plates and being connected to one another by joints having rocker pins. The rocker pins have end faces configured to transmit friction forces between the plate link chain and cone pulleys, wherein at least one of the plates has at least one overlapping tip. The first, second, and third chain links form a triplet and have different plate assemblies comprised of a first plate unit or a second plate unit, each of the chain links having at least one plate positioned transversely to a running direction of the plate link chain and are repeated in the running direction of the plate link chain.

When a chain is wound around a pulley, a pin-pulley contact point as a contact point of a pin of the chain with the pulley slides and moves on a conical surface of the pulley. A contact point slip distance, namely the distance by which the pin-pulley contact point moves on the conical surface at this time, is associated with an offset. The offset is the distance between a pin-pin contact point, which is a contact point between the pins at the time the chain is in a linear state, and the pin-pulley contact point in a y-axis direction. Offsets that minimize the contact point slip distance at the maximum running radius and the minimum running radius of the chain are obtained, and the offset is set between these values. The pin-pulley contact point is set close to the pin-pin contact point of the chain in the linear state.
