Definitions

  • the present invention relates to a skateboard axle assembly with a connection plate for mounting the axle assembly on a skateboard deck and a roller axle with two ends to each of which a roller is mounted.
  • the present invention relates to a skateboard with at least one skateboard axle assembly of the type mentioned.
  • the roller axle is mounted on the connection plate via two pins. Both pins are located in the middle of the roller axis. A first pin is received in a cup on the terminal plate so that the roller axis can rotate around this pin. A second pin, the so-called kingpin, is tilted around the roller axis in relation to the first pin and firmly connected to the connection plate.
  • the Kingpin is usually designed as a threaded pin.
  • the roller axle is mounted on elastic sleeves, which are plugged onto the kingpin on this. Thus, the roller shaft can be pivoted by compression of the elastic sleeves around the first pin.
  • the elastic sleeves are also referred to as steering rubbers.
  • the steering rubbers can be compressed by tightening a so-called Kingpin nut, which is screwed onto the Kingpin, more or less compressed. This will set the hardness of the steering of the skateboard. With a very firm tightening of the Kingpin nut one achieves a very stable and quiet straight run of the skateboard. A less strong tightening of the kingpin nut agile cornering behavior of the skateboard is favored. This is at the expense of stable straight-line stability. To adjust the steering stiffness over the kingpin nut is usually necessary tool.
  • the design of the conventional skateboard axle assemblies with the steering rubbers represents a degressive system. This means that a driver is at the highest point, ie in an unstable position when driving straight ahead. In order to make a turn, he has to tilt the skateboard deck towards one of the side edges, with the skateboard deck sinking slightly towards the ground or lane.
  • a conventional skateboard front axle is mounted on an arm which is mounted about a vertical axis of rotation on the skateboard deck.
  • the axis of rotation is arranged in front of the roller axis.
  • the rotary arm can be blocked or released.
  • a skateboard axle assembly is shown in which a conventional front axle is mounted on a rotary arm.
  • the background of this skateboard axle assembly is to allow reduced curve radii and propel the skateboard forward by pumping.
  • the rotary arm, on which the roller axle of conventional design is mounted, is loaded by a spring in a neutral position. The neutral position corresponds to the straight ahead of the skateboard.
  • DE 10 2006 057 167 A1 shows a skateboard whose front wheels can each be steered about a substantially vertical axis. This can be achieved by tilting the skateboard deck about a longitudinal axis, wherein each front wheel is associated with a trailing arm, which is connected via a connecting strut with the skateboard deck.
  • the object of the present invention is to further improve a skateboard axle assembly which enables both small curve radii and propulsion of a skateboard by pumps.
  • the object is achieved by a generic skateboard axle assembly in which the roller axle is coupled via two articulated arms movable with the connection plate.
  • the skateboard axle assembly is designed so that the connection plate is in a straight line at the lowest point above the roller axis and thus above the ground or the road and that the connection plate is raised when tilted. Accordingly, the driver of a skateboard with the skateboard axle assembly is in a straight-ahead driving at the lowest point. If he wants to drive a curve, he must tilt the skateboard deck towards one of the two facing in the direction of travel edges. The skateboard deck and thus the connection plate of the skateboard axle assembly are slightly raised.
  • the weight of the skateboard driver acts as a restoring force on the skateboard axle assembly, which results in the skateboard axle assembly always being returned to a stable position that corresponds to straight travel, without having to incorporate its own spring elements , A rocking is also excluded.
  • this skateboard axle assembly can be used to propel the skateboard forward Pumps are easily made possible.
  • this construction of the skateboard axle assembly larger steering angles than conventional axles possible, so that smaller curve radii can be realized. For a skateboard driver, this results in a driving experience that is equivalent to surfing or snowboarding.
  • the skateboard axle assembly can be mounted in two orientations on the skateboard deck and can be used as a front axle assembly as well as a rear axle assembly.
  • the two articulated arms are arranged symmetrically with respect to a center axis extending in the direction of travel of the skateboard axle assembly when the skateboard axle assembly is in a neutral position corresponding to the straight run of the skateboard.
