  • Patent number: 9482322
    Abstract: In the field of a slide rail for tensioning and guiding an endless drive member, comprising at least one bore and a screw captively held in the bore, permitting the captive mounting of screws even in thin-walled slide rails is provided. A sleeve is mounted in the bore and the sleeve comprises engagement elements at its end facing the rail, said engagement elements being engaged with the wall of the bore, and a stop collar lying against a stop surface formed at the slide rail, and lock elements are embodied in the sleeve which engage the thread of the screw and lock the screw at least in an assembly position, wherein said slide rail is thin-walled. Furthermore, an assembly method is provided for manufacturing the slide rail with a captively held screw and to the loss prevention device per se.

  • Patent number: 8475307
    Abstract: The invention relates to a tensioning rail for a chain drive with a support body which is pivotable about a center 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.

  • Patent number: 8062157
    Abstract: The present invention relates to a tensioner, in particular a tensioner for a driving chain of an internal combustion engine, comprising a tensioning plunger which is axially movably guided in a plunger bore of a plunger reception means and an adjuster for readjusting the shift of the operating range of the tensioning plunger caused by wear. The adjuster comprises a hydraulic adjusting element and a closable pressure chamber provided on the bottom of the plunger bore. The adjusting element delimits the pressure chamber against the plunger bore and is axially movably guided in said plunger bore.

  • Publication number: 20080113837
    Abstract: A tension or guide rail for a flexible drive means, in particular for a timing chain of an internal combustion engine, with a carrier body and guide track which can be pressed onto the flexible drive means, where the tension or guide rail comprises an installation channel which is independent of the action of the guide track. The carrier body can comprise at least a first and at least a second carrier-body side part, which are permanently joined together and which jointly define the installation channel. Furthermore, an internal combustion engine with a timing drive comprising a flexible drive means and at least one such tension or guide rail, whereby the flexible drive means is in contact with the guide track and an additional component acting interactively with the internal combustion engine extends through the installation channel at least in some regions.
