Problems solved by technology

[0004] A disadvantage of the chains known from the aforementioned documents is that the link plates have only a very small linear contact with the slide rail, which leads to locally higher loads and greater wear on the slide rails and link plates
This causes locally very high wear on the chains and slides

Embodiment Construction

[0032] figure 1 A multi-stage control transmission 10 of a reciprocating piston internal combustion engine of a motor vehicle (not shown) is shown, which has a primary transmission 12 and a secondary transmission 14 . A first chain 18 is installed in the primary drive 12 as a first envelope drive 16 . A second chain 22 is installed in the secondary drive 14 as a second envelope drive 20 . The first chain 18 is driven via a first rotor 24 which is designed as a first gear wheel 26 . By means of the first chain 18 , a second rotor 28 is driven via the primary drive 12 , which is likewise designed as a second gear wheel 30 . The second rotor 28 is part of a one-piece intermediate gear 32 which, in addition to the second rotor 28 , also includes a third rotor 34 which is likewise designed as a third gear 36 . Alternatively, the second rotor 28 and the third rotor 34 can be produced as separate components and connected to one another in a rotationally fixed manner to form a comb...

Abstract

The invention relates to a chain for a control transmission (10) of a reciprocating piston internal combustion engine, which has a plurality of chain plates (66), wherein the chain plates (66) at least partially have plate backbones (68a, 68b) ), the plate backbones (68a, 68b) are in at least partial sliding contact with at least one slide rail (52, 58, 64, 90) when the chain (18, 22) moves around, wherein the at least one link plate (66) The plate spines (68a, 68b) have particularly flat running surfaces (82a, 82b) with a width of at least 0.1 mm, the width of which is smaller than the width of the link plate (66).

Description

technical field [0001] The invention relates to a chain for a control transmission of an internal combustion engine of the reciprocating piston type, which has a plurality of link plates, wherein the link plates at least partially have plate ridges which are at least partially in contact with the chain during the circular movement of the chain At least one rail is in sliding contact. The invention also relates to a control transmission for an internal combustion engine of the reciprocating piston type having such a chain. Background technique [0002] Control drives with envelope drives in the form of chain drives in internal combustion engines of the reciprocating piston type generally have slide rails and / or tension rails for guiding the chain and for counteracting chain vibrations and noises. In the area of ​​the running rails and tensioning rails, the link plates are in contact with the running rails and tensioning rails in parts via their plate spines. This leads to f...
