Definitions

  • the present invention relates to a skateboard axle assembly according to the preamble of claim 1.
  • the present invention relates to a skateboard with at least one skateboard axle assembly of the type mentioned at the beginning.
  • the roller axle is mounted on the connection plate via two pins. Both pins are arranged in the middle of the roller axis.
  • a first pin is received in a bearing socket on the connection plate in such a way that the roller axis can rotate about this pin.
  • a second pin, the so-called kingpin is tilted around the roller axis in relation to the first pin and is firmly connected to the connection plate.
  • the kingpin is usually designed as a threaded pin.
  • the roller axis is mounted on the kingpin via elastic sleeves that are attached to the kingpin. The roller axis can thus be pivoted about the first pin while the elastic sleeves are compressed.
  • the elastic sleeves are also known as bushings.
  • the bushings can be compressed to a greater or lesser extent by tightening a so-called kingpin nut that is screwed onto the kingpin. This adjusts the stiffness of the steering of the skateboard. If you tighten the kingpin nut very firmly, you will achieve a very stable and smooth straight-line run of the skateboard. If the kingpin nut is tightened less strongly, the skateboard's agile cornering behavior is favored. This is at the expense of stable straight-line stability. Tools are usually required to adjust the steering stiffness using the kingpin nut.
  • a conventional skateboard front axle is mounted on an arm that is mounted on the skateboard deck about a vertical axis of rotation.
  • the axis of rotation is arranged in front of the roller axis.
  • the rotating arm can optionally be blocked or released.
  • a skateboard axle assembly is shown in which a conventional front axle is mounted on a pivot arm.
  • the background to this skateboard axle assembly is to enable reduced curve radii and propulsion of the skateboard by pumps.
  • the rotating arm, on which the roller axis of conventional design is mounted, is loaded into a neutral position by a spring. The neutral position corresponds to straight-ahead travel of the skateboard.
  • the DE 10 2006 057 167 A1 a skateboard, the front wheels of which can each be steered around a substantially vertical axis. This can be achieved by tilting the skateboard deck about a longitudinal axis, each front wheel being assigned a trailing arm which is connected to the skateboard deck via a connecting strut.
  • a skateboard axle assembly is also known in which the wheels of the skateboard are tilted when steering.
  • the wheels of an axle are connected to two axles, which can be moved against each other for steering in the direction of the axle.
  • 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 pumping.
  • skateboard axle assembly according to claim 1.
  • the skateboard axle assembly is designed in such a way that the connection plate is at the lowest point above the roller axis when driving straight ahead and thus above the floor or the roadway and that the connection plate is raised when inclined. Accordingly, the driver of a skateboard with the skateboard axle assembly is also at the lowest point when driving straight ahead. If he wants to drive a curve, he has to tilt the skateboard deck in the direction of one of the two edges pointing in the direction of travel. The skateboard deck and thus the connection plate of the skateboard axle assembly are raised slightly. With this design, the weight of the skateboarder acts as a restoring force on the skateboard axle assembly, which means that the skateboard axle assembly is always returned to a stable position that corresponds to straight-ahead travel, without having to integrate its own spring elements .
  • skateboard axle assembly Can be mounted on the skateboard deck in two orientations and can be used as both a front axle assembly and a rear axle assembly.
  • the axes on the roller axis side and the axes on the connection plate side run parallel to a longitudinal direction of the connection plate in a plan view. This results in a neutral driving behavior of the skateboard axle assembly and thus of the skateboard with regard to straight-ahead travel. This means that equally large forces have to be used for left and right turns.
  • the two articulated arms are preferably arranged symmetrically with respect to a central axis which runs in the direction of travel of the skateboard axle assembly when the skateboard axle assembly is in a neutral position which corresponds to the straight-ahead running of the skateboard.
  • the forces in the articulated arms are thus also symmetrical.
  • the axes on the roller axis are preferably spaced apart from one another along the roller axis and the axes on the connection plate are spaced apart from one another along a transverse direction of the connection plate, the distance between the two axes on the roller axis being in particular 2 to 2.5 times as large as the distance between the axes on the connection plate.
  • the transverse direction of the connection plate is a direction defined on the connection plate that is transverse to a direction of travel.
  • the distance information is particularly valid for a neutral position of the axle assembly.
  • the required driving behavior results from the specified distance ratios. In addition, only a small amount of space is required.
  • the articulated arms enclose an angle of 85-95 ° to one another in each deflection position, which angle also remains essentially constant.
  • the two articulated arms are preferably of the same length.
  • the two articulated arms are designed as identical parts.
  • a variant provides that a distance between each of the axes on the roller axis and the associated axis on the connection plate is a maximum of 35% of the distance between the two axes on the connection plate deviates. This results in pleasant and safe driving behavior and little space required.
  • the axes on the roller axis and the axes on the connection plate each enclose an angle of 0 ° -80 ° in a side view with a connection plane of the connection plate.
  • a side view of the skateboard axle assembly which is in a neutral position, only one side surface of the connection plate is therefore visible.
  • the skateboard axle assembly is mounted on a skateboard deck, the skateboard deck is in a horizontal position in this position.
  • the resetting property of the skateboard axle assembly and, on the other hand, the stability of straight-line stability and the agility when cornering can be set via the aforementioned angular range.
  • the angle is chosen so that the desired driving behavior occurs.
  • the axles on the roller axle side and the axles on the connection plate side can be inclined forwards or backwards in a side view in the direction of travel. If the axles are inclined forward in the direction of travel, the axles on the connection plate side are in front of the axles on the roller axle side in the direction of travel and all axles point diagonally upwards and forwards in the direction of travel. If the axle assembly is used in a reversed orientation, the axles on the roller axle side are located in front of the axles on the connection plate side when viewed in the direction of travel. When viewed in the direction of travel, the axes point obliquely backwards and upwards.
  • the axes on the roller axis side and the axes on the connection plate side preferably each enclose an angle of 0 ° -15 °, preferably of 0 ° -10 °, with the connection plane of the connection plate in a side view. These angular ranges are preferred when the skateboard axle assembly is used as the rear axle assembly. In the extreme case, ie when the angle is 0 °, the axle assembly only supports a tilting or rocking movement of the connection plate relative to the roller axis and thus of the skateboard deck relative to the roller axis. There is then no contribution to the steering. The result is a driving experience that is familiar from surfing or snowboarding.
  • the axes on the roller axis side and the axes on the connection plate side in a side view with the connection plane of the connection plate each enclose an angle of 45 ° -80 °, preferably 65 ° -75 °.
  • These angular ranges are preferably used when the skateboard axle assembly is used as a front axle assembly.
  • the angle can be 70 °.
  • the driver of a skateboard with such a skateboard axle assembly thus has a driving experience like surfing or snowboarding.
  • the axes on the roller axis and the axes on the connection plate can run essentially perpendicularly in a front view with respect to an upper connecting plane of the connection plate to the skateboard deck.
  • the front view corresponds to a view against the direction of travel of the skateboard.
  • the skateboard axle assembly is in the neutral position. This results in a neutral coordination of the skateboard axle assembly with regard to left and right turns.
  • the articulated arms are fork-shaped at least at one end to form a joint, the respective end of the articulated arms on the connection plate side preferably being fork-shaped.
  • the part of the joint on the roller axis side or the part of the joint on the connection plate side can also be fork-shaped.
  • exactly three openings for mounting the axle assembly on the skateboard deck are arranged in the connection plate, a first opening lying on a connection plate longitudinal axis and a second and a third opening in the direction of the connection plate longitudinal axis being spaced from the first opening and on opposite sides the connection plate longitudinal axis, the openings are preferably holes or elongated holes.
  • the skateboard axle assembly can be easily and stably mounted on a skateboard deck through these openings with the aid of screws. If the openings are designed as elongated holes, the center distance can be fine-tuned.
  • exactly four openings for mounting the axle assembly on the skateboard deck are arranged in the connection plate, the four openings being arranged in a rectangle that is symmetrical with respect to a connection plate longitudinal axis and are preferably elongated holes.
  • the skateboard axle assembly can be easily and stably mounted on all common skateboard decks.
  • the openings as elongated holes, the skateboard axle can be assembled independently of the selected spacing of the assembly openings in the skateboard deck.
  • the elongated holes can be used to fine-tune the center distance.
  • At least one stop element can be attached to the connection plate in such a way that it restricts a deflection of the articulated arms.
  • the deflection of the articulated arms is limited such that rollers mounted on the roller axle do not come into contact with the skateboard deck when the skateboard axle assembly is mounted on a skateboard deck. This results in a safe driving behavior of the skateboard axle and thus the skateboard.
  • the articulated arms are coupled to the connection plate via an intermediate piece protruding downward from the underside of the connection plate, the intermediate piece preferably being designed in one piece with the connection plate. This results in a simple structure and easy assembly of the skateboard axle.
  • the intermediate piece preferably acts as a stop element. So there are only a few components required for the skateboard axle assembly.
  • the intermediate piece and stop element can, for. B. lie in a neutral position of the skateboard axle assembly between the articulated arms.
  • the blocking position of at least one articulated arm corresponds to a position of the same in the direction of travel or in the direction of the longitudinal axis of the skateboard deck.
  • Another object of the present invention is to provide a skateboard which can be propelled forward by so-called pumping and with which small curve radii can be driven.
  • a skateboard with at least one skateboard axle assembly according to the invention.
  • Such a skateboard on the one hand allows very tight curve radii and on the other hand the skateboard can be propelled by means of pumps.
  • the skateboard preferably comprises a skateboard axle assembly of the type mentioned at the beginning and a conventional axle assembly, the skateboard axle assembly of the type mentioned above preferably being arranged in the front in the direction of travel and the conventional axle assembly preferably in the rear in the direction of travel and steering in the same direction as the front, instead of as was previously the case opposite.
  • Conventional axle assemblies are to be understood here in particular as those skateboard axle assemblies that have rubber bushings and no four-bar linkage.
  • skateboard comprises two skateboard axle assemblies according to the invention and the skateboard axle assemblies are oriented in the same direction or in opposite directions.
  • skateboard axle assemblies are oriented in the same direction, this means that the axles on the roller axle side and the axles on the connection plate side of both skateboard axle assemblies mounted on the skateboard are oriented in the same direction. However, there may be deviations in the angular orientations of the axes on the roller axis and the connection plate-side axes of the two skateboard axis assemblies. If the skateboard axle assemblies are oriented in opposite directions, the axles on the roller axle side and the axles on the connection plate side of the front skateboard axle assembly in the direction of travel point in a different direction than the axles on the roller axle side and the axles on the connection plate side of the rear skateboard axle assembly in the direction of travel.
  • axles on the roller axle side and the axles on the connection plate side of the front axle assembly can point diagonally upwards and forwards in a side view and the axles on the roller axle side and axles on the connection plate side of a rear axle assembly diagonally backwards and upwards in a side view.
  • axles on the roller axle side and the axles on the connection plate side of a skateboard axle assembly of the type mentioned at the rear in the direction of travel can be arranged essentially parallel to a longitudinal skateboard direction. This carries the rear axle does not contribute to the steering of the skateboard. It only supports a tilting or rocking movement of the skateboard deck by allowing this.
