Embodiment Construction

[0032] in figure 1 The timing chain transmission device 1 is schematically shown in FIG. The timing chain transmission device basically includes a crankshaft sprocket 2, two camshaft sprockets 3.1 and 3.2 located above, and placed around the sprockets 2, 3.1, 3.2 The ring-shaped timing chain 4 and the guide rail 5 and the tension rail 6. The tensioning rail 6 is pivotally supported at its pivot point 7 and is pressed against the timing chain 4 by means of a chain tensioner 8 arranged in the part of the engine housing 9 in a manner that is of the chain tensioner 8 The tensioning piston 10 presses against the back side of the tensioning rail 6.

[0033] The guide rail 5 is assigned to the tight side (Zugtrum) of the timing chain drive 1 and is assigned to the loose side (Lostrum) via the tension rail 6. This kind of timing chain transmission device 1 is a highly dynamic device, which on the one hand must solve high rotational speeds and on the other hand must also bear alternat...

Abstract

A tensioning rail for an endless drive, in particular a timing chain drive of an internal combustion engine, comprises a sliding lining body and a reinforcement body inserted in the sliding lining body and connected thereto by a detent connection, the sliding lining body comprising a slide rail for contact with an endless drive and a press-on region for the tensioning piston of a tensioning device. The tensioning rail is characterized in that the press-on region is arranged in a resiliently movable fashion on the slide rail and comprises a detent device as a constituent part of the detent connection such that the detent device is adapted to be locked due to the resilient movement of the press-on region. An endless drive having a tensioning rail of the type disclosed is also provided.

Description

technical field [0001] The invention relates to a tensioning rail (Spannschiene) with a sliding lining body (Gleitbelagkoerper) and a reinforcement inserted into the sliding lining body and connected to the sliding lining body by means of a locking connection (Rastverbindung) Body (Verstaerkungskoerper), wherein the sliding lining body has a contact area for the sliding rail (Gleitschiene) on the ring drive (Endlostreibmittel) and for the tensioning piston (Spannkolben) of the tensioning device. Background technique [0002] Such a tensioning rail is known, for example, from EP1286083A2. The sliding lining body is an injection-molded body produced by means of injection molding, which has a substantially uniform thickness except for the swivel region and the pressing region. On the rear side of the slide rail there is a groove, into which the reinforcement plate is inserted upright. For this purpose, the groove extends over the entire swivel region, while in the pressing re...
