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.

Abstract: A plate for a rocker joint chain in which the plate includes two longitudinal legs and two vertical legs that together enclose a plate opening. The plate includes at least one recess in a longitudinal leg to replace a tab that extends from a longitudinal leg in previously employed plates. A guide rail along which the rocker joint chain travels to reduce slack strand vibrations during chain movement is subject to less wear than with the previously employed plates.

Abstract: A rocker joint chain having a plurality of chain links, each chain link including at least one link plate. The chain links are connected to each other in a pivoting manner at rocker joints, and the rocker joints each include a rocker member having at least two cylindrical rocker pins that contact each other by rolling or sliding on each other.

Abstract: A link chain for use in the continuously variable transmission of the power train in a motor vehicle is assembled of pairs of composite identical or dissimilar links each having a stack of apertured plates, and of coupling units employing pairs of non-circular pins extending through registering portions of apertures in the respective stacks of plates. The pins are designed to cooperate with the plates to limit the extend of inward and outward pivotability of links of the respective pairs from positions of alignment, and the pins carry stops which act alone or cooperate with diaphragm springs or with other types of springs to prevent wobbling of the plates. The plates can be provided with projections which cooperate with the pins to limit the extent of pivotability of the pairs of links relative to each other and/or to prevent jamming of pairs of links in angular positions from which they cannot return to the positions of alignment. Each plate is traversed by two pairs of pins.

Abstract: A plate link chain of the present invention has rocker link elements configured such that the frictional end surfaces have a profile, which deviates from a planar surface in both circumferential and radial orientations. In a preferred embodiment the end surface profiles are defined by radii of predetermined dimensions in the range of 5 to 50 millimeters with the radius formed in the radial plane being larger than the radius formed in the circumferential plane. The radii originate from midpoints, which are located at predetermined distances from the rocking surfaces, to form substantially spherical end surfaces that are either symmetric or asymmetric for selected applications. The substantially spherical end surfaces are designed to reduce the edge transfer forces and tracking error of the rocker link elements and to improve wear characteristics and the stability of frictional engagement of the transmission in operation.
