Abstract
Official abstract text for this publication.
A tensioning rail for a drive chain, in particular for a chain drive of an internal combustion engine, comprises a basic body and a spring unit, the basic body including a sliding surface for contact with the drive chain and a press-on surface. The spring unit comprises a tensioning end arranged on the press-on surface and a support end supportable on a counter bearing, a wear protection element being provided, which is arranged at the support end of the spring unit. In addition, the invention relates to a chain drive including such a tensioning rail as well as to the use of such a tensioning rail for a chain drive of an internal combustion engine.
First claim
Opening claim text (preview).
1 . A tensioning rail for a drive chain comprising a basic body and a spring unit, the basic body including a sliding surface for contact with the drive chain and a press-on surface, wherein the spring unit comprises a tensioning end arranged on the press-on surface and a support end supportable on a counter bearing, wherein a wear protection element is provided, said wear protection element being arranged at the support end of the spring unit. 2 . The tensioning rail according to claim 1 , wherein the spring unit is configured as a leaf spring. 3 . The tensioning rail according to claim 1 , wherein a locking element is provided on the press-on surface of the basic body. 4 . The tensioning rail according to claim 1 , wherein the wear protection element is made of a wear-resistant, low-friction plastic material. 5 . The tensioning rail according to claim 1 , wherein the wear protection element has a curved or semicircular contact surface. 6 . The tensioning rail according to claim 1 , wherein the wear protection element is provided with locking elements for fixing the wear protection element at the support end of the spring unit. 7 . The tensioning rail according to claim 1 , wherein the wear protection element is configured as a sleeve for arrangement on the counter bearing and for contact with the support end of the spring unit. 8 . The tensioning rail according to claim 1 , wherein fastening means are provided on the support end of the spring unit. 9 . A chain drive of an internal combustion engine, comprising a drive gear and at least one driven gear, an articulated chain wrapped around the drive gear and the at least one driven gear, and a tensioning rail contacting the articulated chain, the tensioning rail comprising a basic body and a spring unit, the basic body including a sliding surface for contact with the articulated chain and a press-on surface, wherein the spring unit comprises a tensioning end arranged on the press-on surface and a support end supportable on a counter bearing, wherein a wear protection element is provided at the support end of the spring unit. 10 . The use of a tensioning rail, which comprises a basic body and a spring unit, for a chain drive of an internal combustion engine, wherein the spring unit comprises a tensioning end arranged on the press-on surface of the basic body and a support end supportable on a counter bearing, and wherein a wear protection element is provided between the support end and the counter bearing during operation.
