Problems solved by technology

Furthermore, it is known that such links and flat-link chains formed using such links are limited in their force-transmitting capacity and that there is thus the possibility that first a link is damaged and fails, for example, due to force peaks.
This failure can be manifested as the rupture of the link, wherein starting from this link can cause the failure or rupture of the entire flat-link chain, because of course the other links arranged between the same joints must bear the burden of the rupture together. The force of the link plates transfers the responsibility and thus bears higher loads

Embodiment Construction

[0040] As already described earlier, figure 1 The surface pressure distribution in the area of ​​the contact surface between the pressure piece and the link plate of the known flat link chain is shown. In the transition region between the small radius of curvature marked with K and the large radius of curvature marked with G, a significant maximum value of the contact pressure between the pressure piece and the link plate occurs, wherein the reason for this is the small radius of curvature K combined with the large Radius of curvature jump between the radius of curvature G.

[0041] Attached figure 2 A part of a known CVT flat-link chain 1 is shown, which is composed of a plurality of rocker or pressure pieces 2 , 3 and a link piece 4 . in the attached figure 1 is shown enlarged in figure 2 The region marked with A in , therefore, figure 1 A pressure piece 2 and a link piece 4 are described.

Abstract

The invention relates to a link plate (4) and a plate link chain for a vehicle drive, comprising a plurality of chain links which are connected together in an articulated manner by means pressure parts (2). Said pressure parts extend in a transversal manner in relation to the longitudinal direction of the link chain. Bearing surfaces are embodied on the pressure pieces and chain links, along which the pressure pieces and the chain links are placed on top of each other in order to transmit power. The respective bearing surfaces have an optimum shape.

Description

technical field [0001] The invention relates to a link sheet. Furthermore, the invention also relates to a flat-link chain formed using a link link according to the invention and a chain drive constructed with such a flat-link chain. Furthermore, the invention relates to a vehicle with such a chain drive. Background technique [0002] Link links and flat-link chains of the type mentioned at the outset are known in various ways from the prior art, as will be described later. Furthermore, it is known that such links and flat-link chains formed using such links are limited in their force-transmitting capacity and that there is thus the possibility that first a link is damaged and fails, for example due to force peaks. . This failure can be manifested as a rupture of the link, wherein starting from this link can cause the failure or rupture of the entire flat-link chain, because of course the other links arranged between the same joints must jointly bear the burden of the rup...
