20100029423 | TENSIONING DEVICE FOR A TRACTION MECHANISM DRIVE - A tensioning device for a traction mechanism drive, in particular for a belt drive. The tensioning device can be produced in an advantageous manner from production and design aspects and which offers advantages over known concepts with regard to the wear of the friction surface element in that it has a base part, having a pivot arm, having a torsion spring, which is designed as a coil spring, for imparting a pivoting torque which acts between the base part and the pivot arm and which forces the pivot arm in a tensioning direction, and having a damping device for generating a damping force which counteracts a pivoting movement of the pivot arm counter to the tensioning direction. The damping device includes a friction surface element which, as such, forms a friction surface which serves to impart a friction force, and which is seated on a mating friction surface, wherein the friction surface element is designed as a ring-shaped or ring-segment-shaped component and is forced outward, in a radial direction with respect to the pivot axis, against the mating friction surface by the torsion spring, and wherein the torsion spring has a coil end section which bears against an inner surface of the friction surface element. The torsion spring is designed, at least in the coil end section which bears against the inner surface of the friction surface element, with regard to the spring cross section such that said coil end section is in areal contact with the inner surface of the friction surface element. | 02-04-2010 |

20100120564 | HYDRAULIC BELT TENSIONER COMPRISING A SPECIAL PISTON - A hydraulic belt tensioner for a unit drive or control drive of a motor vehicle. The belt tensioner has a cylinder housing in which a damper piston with a piston rod is arranged to be axially retracted against the force of a compression spring. A damping valve is integrated into the damper piston which, when interacting with a pressure compartment in the cylinder housing, are a component of a hydraulic damping system that is effective in the direction of retraction of the piston rod. The damping piston is produced from a shaped metal sheet piece that is guided inside the cylinder housing with very little play. The interior of the damping piston forms a receptacle for the damping valve configured as a throttle-check valve. | 05-13-2010 |
