Embodiment Construction

[0023] figure 1 A tensioning rail 1 made of an injection-mouldable material is shown. The tensioning rail 1 has a fulcrum 2 . The tensioning rail 1 is designed convexly on the side of the control chain. The tensioning rail 1 is concave on the side facing away from the control chain. exist figure 1 , the control chain is denoted by reference numeral 3 . The tensioning rail has a support body 4 on which a pressing area 5 is formed. The pressing area 5 is part of the protrusion 6 . The control chain 3 extends between the fulcrum 2 and the pressing area 5 of the projection 6 . The pressing area 5 is produced in one piece from the same material as the support body 4 of the tensioning rail 1 . The tensioning rail 1 is produced by injection molding. The pinch area 5 of the projection 6 forms the area where the control chain 3 overlaps. While the control chain 3 runs in the guide channel 7 , this region overlaps the guide channel 7 . This area is referred to as guide channel...

Abstract

The invention relates to a tensioning rail for a chain drive with a support body which is pivotable about a centre of rotation and which has a guide channel, which can be placed in contact with a chain, and a pressing region which can be acted on with pressure by a tensioning piston, wherein the pressing region bridges the guide channel at least in regions by forming a peripherally closed guide channel section, wherein the pressing region is formed in one piece with the support body.

Description

technical field [0001] The invention relates to a tensioning rail for a chain drive with a support body pivotable about a fulcrum, which has guide channels which can be brought into contact with the chain and which can be loaded with pressure by a clamp , wherein the crush region overlaps the guide channel at least partially by forming a guide channel section that is closed in the circumferential direction. Background technique [0002] Tensioning rails with inserted press-on regions are known from the prior art. DE 20 2004 013 921 U1 discloses a tensioning rail for a chain drive, wherein the tensioning rail has a guide channel. In this case, the guide channel is designed so open that the chain can easily be guided over two opposite sides of the tensioning rail and comes into contact with the sliding lining body provided on the bottom side of the guide channel. In DE 20 2004 01 392 U1, the pressure piece with the pressing area is clamped on both sides of the guide channel,...
