Abstract

A guiderail for a traction drive comprising a supporting body including a first surface with a recess that includes a first corresponding cavity. The guiderail further includes a slideway lining configured to contact the first surface, wherein the slideway lining includes a second surface that includes a locking hook that is formed on a first edge of the second surface and protrudes out from the first surface, wherein the locking hook is configured to engage with the recess to prevent the slideway lining from slipping off the supporting body.

Claims

1. A guide rail for a traction drive, comprising:

a supporting body with an active surface and a first and second recess, wherein a longitudinal axis runs along a length of the supporting body;

a slideway lining configured to contact the active surface, wherein the slideway lining includes;

a basic surface in contact with the traction mechanism;

a slideway surface opposite the basic surface;

a first locking hook configured to engage with the first recess to prevent the slideway lining from slipping off the supporting body, wherein the first locking hook is formed on a first edge of the basic surface of the slideway lining and further includes a first undercut configured to interact in a form-fitting manner with the first recess; and

a second locking hook that is formed on a second edge of the basic surface and configured to engage with the second recess to prevent the slideway lining from slipping off the supporting body, wherein the second locking hook includes a second undercut configured to interact in a form-fitting manner with the second recess, wherein the second locking hook is longitudinally offset from the first locking hook relative to a first end of the supporting body along the longitudinal axis.

2. The guide rail of claim 1, wherein the first locking hook and the second locking hook are arranged in longitudinally displaced manner along the slideway lining along the longitudinal axis, wherein the first lock hooking is closer to the first end of the supporting body than the second locking hook.

3. The guide rail of claim 1, wherein the first locking hook includes an L-shaped design configured to partially encompass the active surface of the supporting body.

4. The guide rail of claim 1, wherein the first recess includes a first cavity that is the same size or greater as the first undercut of the first locking hook and a second cavity that is smaller than the second undercut of the second locking hook.

5. The guide rail of claim 1, wherein the slideway lining is configured to be positioned axially on the active surface of the supporting body, wherein the first locking hook and second locking hook penetrate respective first and second cavity simultaneously, and wherein the guide rail includes a form-fitting engagement between the supporting body and the slideway ling that can be implemented by using an axial displacement of the slideway lining on the supporting body in a direction of the second cavity.

6. The guide rail of claim 1, wherein the supporting body is manufactured from metal or polymer material.

7. The guide rail of claim 1, wherein the slideway lining is produced using an injection molding process from polymer material.

8. The guide rail of claim 1, wherein the first locking hook and second locking hook and the first and second recesses are formed identically.

9. A guiderail for a traction drive comprising:

a supporting body including a first surface with a first recess that includes a first corresponding cavity, wherein a longitudinal axis runs along a length of the supporting body; and

a slideway lining configured to contact the first surface, wherein the slideway lining includes a second surface that includes a first locking hook that is formed on a first edge of the second surface and protrudes out from the first surface, wherein the first locking hook is configured to engage with the first recess to prevent the slideway lining from slipping off the supporting body, and a second locking hook that is formed on a second edge of the second surface and protrudes out from the second surface, wherein the second locking hook is configured to engage with a second recess to prevent the slideway lining from slipping off the supporting body, wherein the second edge is opposite the first edge and wherein the first locking hook and the second locking hook are arranged in a longitudinally displaced manner along the slideway lining relative to a first end of the supporting body along the longitudinal axis, wherein the second locking hook is longitudinally offset from the first locking hook relative to a first end of the supporting body along the longitudinal axis.

10. The guiderail for a traction drive of claim 9, wherein the second recess includes a second corresponding cavity.

11. The guiderail for the traction drive of claim 10, wherein the first locking hook is configured to engage with the first recess when the second locking hook is engaged with the second recess.

12. The guiderail for the traction drive of claim 9, wherein the first locking hook includes a groove that is depressed between the first surface and undercut of the locking hook, and the groove is configured to be in contact with the supporting body.

13. The guiderail for the traction drive of claim 9, wherein the first cavity is transverse to a longitudinal axis of the guiderail.

14. The guiderail for the traction drive of claim 9, wherein the supporting body includes a second recess including a second cavity that is smaller than the first cavity, wherein the second cavity is configured to prevent the locking hook from passing through the recess and the first cavity and second cavity are configured to engage with the locking hook simultaneously.

15. The guiderail for the traction drive of claim 9, wherein the first locking hook is configured to secure the slideway lining onto the supporting body.

16. The guiderail for the traction drive of claim 9, wherein the slideway lining includes a slideway surface opposite the second surface, wherein the slideway surface is configured to contact a traction mechanism of an engine.

17. The guiderail for the traction drive of claim 9, wherein the locking hook includes a L-shaped design.

18. The guide rail of claim 9, wherein the first and second recess are arranged in a longitudinally displaced manner along the slideway lining relative to the first end of the supporting body along the longitudinal axis.
