Abstract

A plate link chain for a continuously variable transmission in a motor vehicle comprising chain links. The chain links have link plates coupled to one another by pairs of rocker pins and at least two different sprocket pitches. At least one absorption mass is arranged between two pairs of rocker pins in an absorption space within a link plate inner contour.

First claim

The invention claimed is:

1. A plate link chain for a continuously variable transmission in a motor vehicle, comprising:
chain links having link plates coupled to one another by pairs of rocker pins and having at least two different sprocket pitches, wherein at least one absorption mass is arranged between two pairs of rocker pins in an absorption space within a link plate inner contour of one of the link plates and no absorption masses are installed in an outer link plate of the plate link chain.

2. The plate link chain as claimed in claim 1 , wherein the at least one absorption mass is arranged between the two pairs of rocker pins within the link plate inner contour, and has a defined play in a direction transverse to a chain longitudinal direction, such that the at least one absorption mass can perform absorption movements in the direction transverse to the chain longitudinal direction during an operation of the plate link chain.

3. The plate link chain as claimed in claim 2 , wherein the defined play in the direction transverse to the chain longitudinal direction varies over the link plates of the plate link chain.

4. The plate link chain as claimed in claim 1 , wherein the at least one absorption mass is arranged in such a way that the at least one absorption mass is prevented from falling out of the absorption space.

5. The plate link chain as claimed in claim 1 , wherein the absorption mass is arranged in a double link plate.

6. The plate link chain as claimed in claim 1 , wherein the at least one absorption mass is approximately of a same thickness as the link plate or thicker than the link plate.

7. The plate link chain as claimed in claim 1 , wherein the at least one absorption mass is of plate-shaped design.

8. The plate link chain as claimed in claim 1 , wherein the absorption mass is of round, oval, ball-shaped or spherical design or of polygonal design with rounded corners.

9. The plate link chain as claimed in claim 1 , wherein a plurality of absorption masses are arranged in the absorption space.

10. The plate link chain as claimed in claim 1 , wherein each sprocket pitch in the at least two different sprocket pitches corresponds to a spacing between two pairs of rocker pins within the inner link plate contour in a chain longitudinal direction.

11. A plate link chain for a continuously variable transmission in a motor vehicle, comprising:
a plurality of link plates coupled to one another by pairs of rocker pins and having at least two link plates of different length, wherein:
each link plate includes an absorption space arranged between two pairs of rocker pins
at least one absorption mass is arranged within the absorption space of one of the link plates in such a manner that the absorption mass can move freely to a limited extent and
no absorption masses are installed in an outer link plate of the plate link chain.

12. The plate link chain as claimed in claim 11 , wherein the at least one absorption mass is sized and arranged in the absorption space in such a way that the at least one absorption mass substantially fills the absorption space.
