Abstract

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.

First claim

What is claimed is:

1. A plate link chain for a continuously variable transmission of a motor vehicle, said plate link chain comprising: longer and shorter chain links that include respective longer and shorter link plates that are coupled to each other by pairs of rocker pressure members, wherein both the shorter link plates and the longer link plates have more than two longitudinally extending external appendages located at external corner regions of the shorter link plates and the longer link plates.

2. A plate link chain according to claim 1 wherein each of the shorter link plates and the longer link plates have four longitudinally extending external appendages.

3. A plate link chain according to claim 1 , wherein the longitudinally extending external appendages extend along and serve to elongate long sides of the shorter link plates and the longer link plates.

4. A plate link chain according to claim 1 , wherein the plate link chain includes only shorter link plates and longer link plates.

5. A plate link chain according to claim 1 , wherein the shorter link plates and the longer link plates each have an opening.

6. A plate link chain according to claim 1 , wherein all the shorter link plates of the plate link chain are designed the same.

7. A plate link chain according to claim 1 , wherein all the longer link plates of the plate link chain are designed the same.

8. A link plate for a motor vehicle chain comprising:
a left link plate side strap comprising a first upper end and a first lower end;
a right link plate side strap comprising a second upper end and a second lower end;
an upper link plate strap, longer than the left link plate side strap and the right link plate side strap, joining the first upper end to the second upper end;
a lower link plate strap, longer than the left link plate side strap and the right link plate side strap, joining the first lower end to the second lower end; and,
at least two longitudinally extending external appendages that extend along and effectively elongate the upper link plate strap, the lower link plate strap, or both of the upper link plate strap and the lower link plate strap.

9. The link plate of claim 8 wherein the at least two longitudinally extending external appendages is four longitudinally extending external appendages that extend along and effectively elongate each end of the upper link plate strap and each end of the lower link plate strap.

10. The link plate of claim 9 wherein:
the upper link plate strap is joined to the left link plate side strap at a first corner region and to the right link plate side strap at a second corner region;
the lower link plate strap is joined to the left link plate side strap at a third corner region and to the right link plate side strap at a fourth corner region; and,
the four longitudinally extending external appendages extend from the first corner region, the second corner region, the third corner region, and the fourth corner region, respectively.

11. The link plate of claim 8 wherein the upper link plate strap or the lower link plate strap is joined to the left link plate side strap or the right link plate side strap at a first corner region and a one of the at least two external appendages is located at the first corner region.

12. The link plate of claim 8 further comprising an opening.

13. A plate link chain for a continuously variable transmission of a motor vehicle comprising:
a shorter one of the link plate of claim 8 ;
a longer one of the link plate of claim 8 ; and,
a pair of rocker pressure members coupling the shorter one of the link plate to the longer one of the link plate.

14. A plate link chain for a continuously variable transmission of a motor vehicle comprising:
a plurality of shorter ones of the link plate of claim 8 , all designed the same;
a plurality of longer ones of the link plate of claim 8 , all designed the same; and,
a plurality of pairs of rocker pressure members coupling the plurality of shorter ones of the link plate to the plurality of longer ones of the link plate.
