Definitions

  • the present invention relates to a height-adjustable spring bearing for a spring operatively disposed between a vehicle body and an unsprung wheel carrier.
  • a spring carrier with a height-adjustable spring plate has become known from DE 102 37 644 B4.
  • the spring carrier has an axially movable spring plate, wherein an actuator with a rotor relative to its stator generates a rotational movement, which is converted by a transmission in an axial movement of the spring plate.
  • the actuator is housed in a housing which is supported above a passage opening in the vehicle body for the spring carrier.
  • Object of the present invention was to provide a height-adjustable spring bearing according to the features of the preamble of claim 1, which can be installed even in confined spaces.
  • this object is achieved by the height-adjustable spring bearing according to claim 1.
  • the single FIGURE shows a height-adjustable spring bearing 1 in longitudinal section.
  • a trained as a helical compression spring spring 2 is disposed between an only indicated here vehicle body 3 and also also indicated only unsprung wheel carrier 4.
  • the spring bearing 1 is a lower spring bearing for the spring 2, while an upper spring bearing 5 is formed on an upper spring plate 6.
  • the lower height-adjustable spring bearing 1 is connected to an actuator 7, upon actuation of which the lower spring bearing 1 is displaceable along the screw axis of the helical compression spring.
  • the actuator 7 has an electric motor 8, and a gear 9 connected to this electric motor 8.
  • a strut 10 has both the spring 2 and a shock absorber tube 11 on, which includes a piston 12 and a cylinder 13 in the usual way.
  • the lower spring bearing 1 is mounted on the damper tube 11, which will be further explained below.
  • the gear 9 is presently designed as a screw, namely as a ball screw 14, wherein a tubular threaded spindle 15 is rotatably supported by roller bearings 16 on a bearing sleeve 17.
  • the bearing sleeve 17 is mounted on the jacket of the shock absorber tube 11.
  • the threaded spindle 15 is provided on its outer circumference with a helical ball groove 18.
  • a spindle nut 19 is rotatably mounted on the threaded spindle 15 via balls 20.
  • the balls 20 roll on the one hand on the helical ball groove 18 and on the other hand on a corresponding helical ball groove 21 in a known manner, which is formed on the inner circumference of the spindle nut 19.
  • the spindle nut 19 is provided with an integrally formed radial board 22, which also forms the lower spring bearing 1 as a spring plate.
  • the figure shows that the helical compression spring 2 is supported at its lower end to this radial board 22.
  • the threaded spindle 15 is provided with a coaxial toothed ring 23, with which a drive pinion 24 of the electric motor 8 meshes.
  • the figure shows that both the actuator 7 and the lower spring bearing 1 are arranged on the side of the unsprung wheel carrier 4.
  • the spring plate, the threaded spindle 15, the bearing sleeve 17 and the strut 10 are arranged coaxially with each other.
  • the present invention can be conveniently provided with a so-called fail-safe device.
  • this FaN-Safe device can be activated. It prevents unwanted rotation of the spindle nut 19 and thus an undesirable lowering of the lower spring bearing 1 when the electric motor is switched off.
  • the lower adjustable spring bearing and the actuator can also be mounted, for example, on a - also unsprung - Radlenker.
