Traction Mechanism Drive
First Claim
1. Traction mechanism drive of an internal combustion engine, comprising an endless traction mechanism which connects a drive wheel and at least one driven wheel in a formfitting manner and on the circumference of which at least one pressure medium-actuated tensioning device and a guide rail having a support body and a sliding lining body which is fastened to the support body on the side of the traction mechanism are arranged, wherein the guide rail is configured so as to be adjustably movable at least partially normally with respect to the traction mechanism, is acted on with an adjusting force by at least one spring element in the direction of the traction mechanism and is provided at least with an outer stop for delimiting an adjusting movement oriented away from the traction mechanism.

Abstract
The invention relates to a traction mechanism drive, in particular a control drive of an internal combustion engine, comprising an endless traction mechanism which connects a drive wheel and at least one driven wheel in a form-fitting manner and on the circumference of which at least one pressure medium-actuated tensioning device and a guide rail (1) having a support body (4) and a sliding lining body (2) which is fastened to the support body (4) on the side of the traction mechanism are arranged.
To avoid inadmissible relaxation of the traction mechanism, in particular in the event of an engine start after a relatively long downtime, the guide rail (1) is configured so as to be adjustably movable at least partially normally with respect to the traction mechanism, is acted on with an adjusting force by at least one spring element (14) in the direction of the traction mechanism and is provided at least with an outer stop for delimiting an adjusting movement oriented away from the traction mechanism.
