Abstract: A belt tensioning device has a torsion spring assembly and a damping assembly with a housing with a longitudinal axis A. A torsion spring is positioned in the housing so as to extend coaxially relative to the longitudinal axis A and which, by means of one of its ends, is secured in the housing in a rotationally fixed way. A tensioning arm is supported relative to the housing so as to be oscillatingly rotatable around the longitudinal axis A and is connected to the other end of the torsion spring in a rotationally fixed way. A tensioning roller is supported at a free end of the tensioning arm so as to be rotatable around an axis of rotation B and extending parallel relative to the longitudinal axis A. The damping assembly surrounds the housing coaxially relative to the longitudinal axis A and comprises cylindrical friction face pairs.

Abstract: Axial corrugated spring comprising an annular spring band 11 which describes a corrugation line oscillating about a radial reference plane around the circumference, wherein the corrugation line has maxima 12, 13, 17 of different height and minima 14, 15, 16 of different height.

Abstract: A wheel suspension with a wheel-guiding strut in provided which includes a helical compression spring, a shock absorber, and a suspension arm, and which is connected to a body and to a wheel. The helical compression spring is preferably made such that it at least partially compensates for transverse forces on the shock absorber or on the piston rod of the shock absorber. Provisions are made for reducing or minimizing or eliminating the force which is delivered to the steering mechanism and which results from the difference between the components of the helical compression spring forces FF acting in the direction of travel, and thus the reaction forces RF, on the left and right sides of the vehicle.

Abstract: A belt tensioning device for a continuous belt drive. The device includes a torsion spring assembly (20) with a longitudinal axis (A2) and with at least one torsion bar or torsion tube (32). The torsion spring assembly (20) can be clamped axially and in a rotationally fast way into a rack. A tensioning arm (19), at one end, is arranged at the torsion spring assembly (20) so as to be aligned approximately radially relative to the longitudinal axis (A2). A tensioning roller (15) is rotatably fixed at the other end of the tensioning arm (19). The axis of rotation (A1) of the tensioning roller (15) extends substantially parallel relative to the longitudinal axis (A2) of the torsion spring assembly (20), and the tensioning arm (19) can be resiliently supported relative to the rack so as to oscillate around the longitudinal axis (A2).

Abstract: A spring with constant cross-sectional area for torsion and/or flexional strain is provided which includes a plurality of individual rods with a round or polygonal cross-section substantially identical to one another and unchanging over their length. In each case, the rods have line or surface contact with other rods and form a bundle held together at least at the ends of the rods. The rods can be round, hexagonal or isosceles triangular in cross-section, and the number of rods is 3n or 3n+1, whereby n is a natural number greater than or equal to 3. Alternatively, the rods can be octagonal or square in cross-section and the number of rods is 4n or 4n+1, whereby n is a natural number greater than or equal to 2.

Abstract: A coil spring (1) and support bearing (2) arrangement for suspension struts (3) with a shock absorber, supporting a steering knuckle of an automobile has a rolling-contact bearing (7), with an axis (x); a receiving body (6), arranged below the rolling-contact bearing (7) in which the rolling-contact bearing is inserted; and a coil spring (1). The coil spring (1) has a force application line (f), which is offset relative to the axis (x) of the rolling-contact bearing (7) at an angle (a). The coil spring (1) has a first portion (8), which, starting from the winding end (17), winds around the receiving body (6). The first portion (8) abuts the receiving body (6). The winding end (17) of the coil spring (1) is arranged in the area of the plane E1 formed by the force application line (f) and the axis (x).
