Definitions

  • the invention relates to an axle assembly for two-wheelers, in particular for bicycles, wherein the axle assembly comprises a quick-release axle with an insertable in the end of a fork, a rocker, a rear end or the like holder support shaft as a support member for a hub and wherein the axis is a threaded end and on other end has a quick release with a clamping lever.
  • the invention also relates to a clamping holder with a quick release, an axle and a lock nut, wherein the axis has a threaded end and at the other end the quick release with a clamping lever, in particular for an axle assembly for two-wheelers, especially for bicycles.
  • Such clamping brackets are known, for example, in the case of quick-release axles but also in the case of clamped fasteners, for example the seatpost.
  • Quick-release axles have the advantage that they can be mounted and removed without tools, in each case only the clamping lever is to be operated.
  • a fail-safe is prescribed at least for front wheels, which prevents the front wheel from the fork when the quick release is open.
  • the advantages of the quick release axles in favor of safety are partially lifted.
  • the lock nut of the quick release must be held with one hand, so that with the other hand, the axis of the quick release on the lever something can be unscrewed further.
  • Object of the present invention is to provide an axle assembly for two-wheelers of the type mentioned, in which the handling during disassembly and assembly of the quick-release axle or the wheel is simplified, while a correct positioning of the axle assembly and a secure connection with the fork, a rocker, a rear end or the like holder are possible.
  • one of the Receiving ends of the fork, the rocker, the rear end or the like holder or connectable to the receiving end intermediate carrier part has a screw thread for screwing a threaded end of the axle.
  • This can be screwed in the mounting of the wheel after insertion of the hub with the quick-release axle in the receiving ends of the fork, the rocker, the rear end or the like holder, the screwed end of the axle in the screw, this can be done with one hand, while the other hand is available for holding the two-wheeler in a suitable, aligned position.
  • the correct, correct positioning of the axis in the receiving ends of the fork is thereby substantially simplified.
  • a sliding limit is expediently provided for the hub cross-axis, preferably an attached to the axis, located within the hub stop.
  • an adjusting ring can be mounted on the axle, which is arranged so that the axle can move out of the hub far enough that the screwed-in end of the axle can be screwed out of the screw-in thread.
  • the stop on the side facing the quick release is inside of the hub.
  • the stopper is designed so that the quick-release axle rotates in the hub and can be moved axially within a certain range.
  • a particularly advantageous further development of the invention provides that the screw-in thread of the receiving end or into the screw-in thread of the intermediate carrier part connected to the dropout, an adjustable stop, is provided for limiting the screw-in depth of the axis thread end m. This contributes significantly to the fact that the attachment of the quick release axle is repeated with the appropriate tension and thus a secure connection is created. The correct position for the quick release must therefore not be sought by trying and more or less screwing the axis m the screw thread, but the quick release is simply screwed in until the stop once set and the clamping lever is then transferred to fix the wheel.
  • the stop for limiting the depth of engagement of the axle threaded end m the screw thread is suitably formed by a stop screw, which is preferably screwed into the screw thread for screwing in the axle threaded end or m an axially subsequent thread.
  • an intermediate carrier part with a screw thread for the axle Be provided threaded end instead of the screw thread directly in the receiving end of the fork, the rocker, the rear end or the like bracket, an intermediate carrier part with a screw thread for the axle Be provided threaded end.
  • the intermediate carrier part may in particular be a threaded bush with internal and external threads or a stepped bush with an internal thread.
  • the internal threads in each case form the screw thread for the axle-threaded end, while the external thread or the gradation is used to connect to the receiving end.
  • an adapter part may be provided, which serves for receiving the axle-Gewmdeendes or the intermediate carrier part and on the other hand is connectable to the receiving end.
  • the adapter part thus has connection means for connection to an intermediate carrier part or a screw-in thread for the axle-end of the trunk and also connecting means for fixing to the receiving end of the fork, the rocker, the rear construction or the like holder.
  • the adapter part is provided directly with a screw-in thread for the axle-threaded end, the adapter part also forms an intermediate carrier part.
  • the adapter part can be screwed, glued or otherwise fastened on the outside at the receiving end.
  • the adapter part can also be a modified lock nut with mounting option at the receiving end.
  • the respectively provided attachment and support of the threaded part on the outside at the receiving end serves to fix the position, ie keeps the adapter part in the intended position and secures it to rotate when screwing in the axle end of the trunk or an intermediate carrier part.
  • a particularly advantageous embodiment of the invention provides that the intermediate carrier part is designed as a simple lock nut, the lock nut a central Screw-in thread for the axle threaded end and a stop screw is screwed directly into the central screw thread.
  • means are provided for securing and / or complicating a rotational movement of the stop screw in the lock nut. The once set stop position remains thereby safe.
  • an intermediate bushing part which can be screwed into a receiving thread of the receiving part or of the adapter part, which has an external fastening thread and an internal thread as a screw-in thread for screwing in the axle threaded end.
  • the threaded bushing can be dimensioned so that on the one hand a sufficient screwing depth for the axis thread end is present and on the other hand so that from the outside of the stop for limiting the depth of engagement of the axle threaded end can be screwed.
  • the adapter part can have a receiving thread for the threaded bush having an outside fastening thread which has the screw-in thread for screwing in the axle threaded end.
  • the threaded bushing is screwed into the adapter part, into which in turn the axial thread end and a stop screw can be screwed.
  • the rotational position of the quick release lever is adjustable.
  • the quick-release lever In its closed position, the quick-release lever should always point backwards or forwards in relation to the direction of travel, so that this lever does not get stuck in the scrub, for example, and then there is a risk that it will be unintentionally opened while driving.

  • the quick release at m the threaded bush screwed axle-threaded end can be rotated so far until a suitable position with respect to the rotational position of the clamping lever is set.
  • the threaded bushing can be rotated until the axial position of the axle fits for an intended clamping force of the quick-release.
  • a stop screw which can be screwed into the threaded bushing and which can be designed as a threaded pin this screwing depth of the axle threaded end is then determined.
