Definitions

  • the invention relates to a towing device according to the preamble of claim 1.
  • a towing device known from DE-GM 77 08 094
  • Such a device provides a tiller-like connection between a towing vehicle and a towed vehicle, the drawbar thus being connected to a front wheel of the towed vehicle Vehicle is connected that both the towing forces when pulling or braking as well as the steering forces are transmitted directly.
  • the advantage of simple and compact design is
  • the object of the invention is to create a towing device which avoids the disadvantages of external towing force introduction such as skewing and the risk of breaking out, but is nevertheless inexpensive to manufacture and in particular easy to transport and simple and also uncritical to use.
  • this object is achieved with a towing device according to claim 1.
  • Such a towing device brings about a separation of steering and towing effects on the towed vehicle, the towing rod itself allowing an essentially rigid direct longitudinal connection between the vehicles.
  • the tow bar will typically have to be connected to the towing vehicle at the front via a trailer coupling, although this detail is not important.
  • the pivotable coupling end of the towing bar can also be designed in the form of one of many known configurations. For example, a ring, hook or shackle element can be provided in order to pivotably engage in a front towing eye on the towed vehicle.
  • the tracking linkage only has to ensure the tracking of a front wheel.
  • Various solutions are available to the person skilled in the art for the designs of such a guiding linkage, for example if he starts from a steering lever-type connection of the wheel and produces a length compensation for the towing bar by means of sliding bearings and / or pivot bearings.
  • the length compensation produced in this way absorbs the longitudinal displacement between the towing bar which can be pivoted about the coupling end and the pivot point of the tracked wheel.
  • a particularly simple length compensation could, for example, be designed in the form of a sliding bearing on the towing rod, which at the end detects a steering lever-like guide rod so that it can be moved and rotated.
  • a guide linkage is preferably provided which contains two vertical hinge joints which are parallel to one another so that these two vertical joints are connected to the steering axis of the wheel and to the. Pivot of the coupling end form a four-bar link. This results in a particularly simple, yet play-free and smooth-running form of the guiding linkage.
  • connection of the guiding linkage to the wheel is expediently carried out via a connection unit which can be flange-mounted or otherwise attached to the wheel and which can be rotated relative to the guiding linkage about a horizontal bearing which can be aligned with the wheel bearing.
  • a connection unit which can be flange-mounted or otherwise attached to the wheel and which can be rotated relative to the guiding linkage about a horizontal bearing which can be aligned with the wheel bearing.
  • OMPI 2 Front view of the wheel connection to the towing device according to FIG. 1 and FIG. 3 Detail of the towing device according to FIG. 1.
  • FIG. 1 shows a towing device designated overall by 1, which is connected on the front side to a towing vehicle 3, for example a car, via a trailer coupling 2 - the trailer coupling typically not having longitudinal and transverse forces but introduces moments into the towing device 1.
  • the towing device 1 is connected to a towed vehicle 4, at two different points and with separate towing and steering functions.
  • the control of the towed vehicle which comes to a second driver when towing with a towing bar and is lent to a second driver, is automatically effected in the towing device by a total of 8 guiding linkage.
  • the guiding linkage 8 consists of an articulated arm with a first arm member 9, which is fixed or ascertainable branching from the towing rod 5, and two further arm members 10 and TT, which are connected to the arm member 9 and 10 via vertical hinges 12 and 13 with vertical axes connect.
  • a pivot bearing 14 with a horizontal axis, which comprises a wheel connection 15.
  • the wheel connection 15 is coaxial on one. Flanged the front wheel 16 (here the right one) of the towed vehicle 4.
  • the front wheel 16 typically has a pivot point 17 that coincides approximately with the tire contact area, while the other articulated front wheel 18 has its own pivot point when the steering wheels are individually suspended and is connected to the wheel 16 via the vehicle's own steering linkage.
  • the alignment and movement of the guiding linkage lies essentially in a horizontal plane
  • the function of the guiding linkage from * Fig. 1 as a quadrilateral joint from the joints 12 and 13 in the guiding linkage, the Radans ⁇ hlu-B 15 or (more precisely) the pivot point 17 and the towing eye 7 can be understood as vertical-axis joints.
  • This quadrilateral joint causes the tracking, d. That is, that a deflection of the tow bar to the left or right also leads to a corresponding IeTkeinschlag.
  • a particularly simple geometric case provides an articulated quadrilateral in the manner of an articulated parallelogram.
  • a wheel 16 aligned in a starting position parallel to the towing bar 5 will always run parallel to the towing bar even in the case of steering locks and thus will not have to absorb any transverse forces which are directly introduced via the towing bar.
  • FIG. 1 shows an approximate joint parallelogram, in which the eccentric arrangement of the towing eye 7 on the towed vehicle 4 is taken into account for a modification. Furthermore, it can be taken into account that the steering linkage is the front wheels. 16 and 19 are usually not strictly parallel, but rather spread their alignment towards the front when there are strong steering angles.
  • FIG. 2 shows further details of the edge connection 15 f as it is fastened to a rim 19 with a wheel hub 20.
  • the RadanschluB 15 should be simple but reliable with the wheel. be connectable that-ß the pivot bearing T4- aligned with the wheel hub axis and that thus the wheel connection can rotate with the wheel, while 15 steering forces can be applied to the wheel 16 from the outside via the pivot bearing 14 and the wheel connection. This is achieved in that the wheel connection 15 "is supported on the rim 19 with a good positive fit and is only tightened by a bolt 21 (as an extended wheel bolt) against the rim 19 or wheel hub 20.
  • the wheel connection 15 consists of a central rotating star 22 which can be rotated via the bearing 14 and has a plurality of feet 23 which are preferably directed outwards and which nestle into the rim flange of the rim 19.
  • the feet 23 are releasably fastened with respect to the rotary star 22 by means of screw connections 24 in order to enable displacement and thus adaptation to different rim sizes and shapes.
  • An alternative design of the edge connection provides symmetrically adjustable feet in the manner of an expandable tripod tripod.
  • the bolt 21 can at least in the radial direction. are displaced in order to enable easy adaptation to different rims.
  • the feet 23 To mount the wheel connection 15, on the one hand, the feet 23 must be adjusted or closed. check and on the other hand only loosen a wheel bolt from the wheel 16 in order to put the bolt 21 in its place through the rotary star 22 and thus to fix the wheel connection 15 - a practical, time-saving attachment.
  • Adjustment of the guide rod 8 is to be provided in order to different arrangements of a towing eye 7 or another fastening point in the vehicle to be towed relative to the turning point 17 of the wheel ' .
  • 'In FIG. 3 is constituted by a sliding joint 25 between the arm member 9 and the tow rod 5 provided a "possibility 5 to move the arm in the longitudinal direction of the tow bar and also to ver ⁇ pivot about the longitudinal axis of the tow rod 5.
  • Such a slide hinge is to of an adjustment (again), for example by means of a clamping screw
  • a lockable swivel joint can also be provided at the location of the slide joint 25 and that other lockable rotary or slide devices can also be provided in the guide linkage can be to provide a sufficient range of adjustability.
  • the four-bar linkage is only one of many conceivable designs of a guiding linkage. If, for example, the sliding sleeve 25 were not fixed in FIG. 3 and instead the rotary joint 13 (FIG. 1) was omitted or blocked, there would be a different, also length-compensating guiding linkage. Likewise, a guiding linkage with a sliding bearing in the area of the arm members 10 or 11 in connection with one of the joints 12 or 13 can form a guiding linkage.
  • the pivot bearing would be left out, for example, of a guide linkage engaging the steering lever of a wheel or the steering linkage. It is only because of the poor accessibility of the steering linkage that a guide linkage acting on the outside of the wheel is preferred.
