  • Patent number: 10605348
    Abstract: A compression ring of a chain sprocket is provided with improved wear characteristics and damping to match various forms of link plates of a chain assembly. The chain assembly includes a plurality of longitudinal link plates hingedly connected by a plurality of pins. The compression ring includes two arrays of compression pads, each array defined by a different profile. Each array of compression pads can be matched to two corresponding groups of link plates. Multiple forms of compression pads and link plate geometries can be accommodated. Compression pad damping force can be tuned by adjusting the width and/or height of the link plates.
    Type: Grant

  • Patent number: 9556963
    Abstract: The invention relates to an overpressure valve (1) which is in the form of a one-way valve or a check valve and which includes a pot-shaped housing (2) with a base (3) and central opening (4) and which also has a valve seat (6) which interacts with a spring-loaded closing body (7). A guide sleeve (9) is inserted with a force fit or form fit into the housing (2) for the purpose of receiving a compression spring (8) which exerts a load on the closing body (7), which guide sleeve simultaneously ensures a construction of the overpressure valve (1) which is secured against falling apart.

  • Patent number: 8905877
    Abstract: A tensioning device for an endless traction element in an engine. The tensioning device has a housing, a plunger, which can he moved in the housing, a compression spring arranged in the plunger, a nonreturn valve arranged between the plunger and the housing, a cylinder arranged in the plunger, and an engagement element. The plunger and the cylinder are connected to one another by a latching system via engagement of the engagement element, and the cylinder is connected materially to the nonreturn valve.

  • Patent number: 8550943
    Abstract: A traction engine drive (2), the components of which are integrated into an assembly unit (6) that can be pre-completed. A guide rail (7) having a clamp rail (10) is fixed in location by a clamping device (16) and a traction element (12) is disposed in conjunction with at least one traction mechanism wheel, so that a free length of the traction element is not present.

  • Publication number: 20110251000
    Abstract: A tensioning device for an endless traction mechanism for a motor is provided and includes a housing (1) that has a cylinder chamber (9) for holding hydraulic fluid, a piston (2) that is supported so that it can slide in the cylinder chamber (9) and is biased by a spring (3), and a valve (4) that is arranged on the base (10) of the housing (1) and connects the cylinder chamber (9) to an oil supply space (8) . In the base (10) of the housing (1), there is at least one groove (5) that allows a ventilation of the cylinder chamber (9).

  • Publication number: 20110015014
    Abstract: A tensioning system (1) configured as a module solution and which has a drive gear (3) and a driven gear (5) connected via a tensioning element (4). A carrier element (8) is disposed in an installation space (6) that is limited by the tensioning gears, the drive gear (3) and the driven gear (5) and a tight side (13) and a slack side (16) of the tensioning element (4). All components of the tensioning system are captively combined via the carrier element (8) to form an externally pre-mountable assembly, that can be delivered, for example, to an internal combustion engine.
