A plate-link chain, in particular for a continuously variable transmission of a motor vehicle, having plate links which are connected to each other in an articulated manner by pairs of rocker pressure members, each including two rocker pressure members. The plate links and the rocker pressure members are designed in such a way as to bear against each other at respective flat contact surfaces so that the load on plate-link bands of the plate links is nearly torque-free during operation of the plate-link chain.

A plate link chain for a continuously variable transmission of a motor vehicle. The chain is formed from longer and shorter chain links that are formed from and that include respective longer and shorter link plates that are coupled to each other by pairs of rocker pressure members. Both the shorter link plates and the longer link plates have at least one longitudinally extending external appendage.

In a chain belt having: plurality of link plates each provided with a pin hole; plurality of connecting pins to connect a part of the plurality of link plates in an endless annular form by being inserted into the pin holes across the part of the plurality of link plates in a state where the part of the plurality of link plates are overlapped; and a retainer pin welded to an end portion of the connecting pin and engaged with the link plate to prevent the link plate from coming off the connecting pin, the retainer pin is disposed in a posture in which an outer circumferential surface is in contact with an outer circumferential surface of the connecting pin, and a plurality of points on the outer circumferential surface of the retainer pin separated from each other in the circumferential direction are welded to the connecting pin.

A drive belt includes a hoop and multiple elements joined together in a loop by the hoop. Each element has an assembly space into which one end portion of the hoop is inserted during assembly. Each element is configured such that a first opening width, which is a distance between a first hook and a second hook, is less than a width of the hoop, and a second opening width, which is a distance between the second hook and a contact site where the one end portion of the hoop housed in the assembly space contacts a first pillar, is greater than the width of the hoop. The first hook and the second hook respectively include a first displacement-restriction surface and a second displacement-restriction surface each configured to restrict relative displacement between the element and the hoop by contacting a corresponding one of edges of the hoop.

Among a plurality of layers of metal rings, an inner circumferential projection is formed on an inner circumferential surface of at least one metal ring, and an outer circumferential projection is formed on an outer circumferential surface of the outermost metal ring. Thus, cracks extending from a surface of the metal ring can be arrested by the inner circumferential projection and the outer circumferential projection. Moreover, the outer circumferential projection of the outermost metal ring that does not abut against any other members is set to have a smaller projection height than the inner circumferential projection that abuts against other members. Thus, even if the inner circumferential projection wears by abutting against the other members, the inner circumferential projection can remain and arrest extension of the cracks; also, the projection height of the outer circumferential projection is reduced to enhance flatness of the outer circumferential surface of the metal ring.

A plate link chain for a continuously variable transmission in a motor vehicle. The chain includes longer and shorter chain links that include longer and shorter link plates that are coupled to each other by pairs of rocker pressure pieces. The plate link chain includes only two types of link plates, namely shorter link plates and longer link plates.
