Definitions

  • the invention relates to a device for lifting a vehicle equipped with rubber tires, in particular a motor vehicle.
  • Devices of this type either serve to load rubber-tired vehicles onto railway wagons or ships or, for example, to remove incorrectly parked or no longer drivable motor vehicles in the raised or loaded state. In this case, it is sometimes only necessary to lift the vehicle to be towed instead of only all the wheels on one axle, but then, as in most other applications, it is just as important to protect the vehicle from damage.
  • the object of the invention is therefore to make available a device with a simpler construction and easier handling.
  • the device created by the invention to achieve the object is characterized in that the gripping devices two longitudinally displaceable parallel to the wheel axis against the force of pressure storage elements against each other, pressing with clamping legs against the inside of the tire and the outside of the tire, by means of an automatically acting, manually released locking has clamp parts held in engagement with the rubber tire.
  • the suspension used to lift the supporting frames can be expediently only attached to one of the two trays forming a supporting frame.
  • a particularly expedient embodiment of the claimed device is obtained if the clamp parts of the gripping directions are essentially hollow cylindrical, the clamp parts pressing with their clamping limbs against the inside of the tire being guided in the clamp parts starting directly from the support arms and pressing with their clamping limbs against the outside of the tire the pressure storage elements are arranged within both bracket parts.
  • the locking device holding the clip parts in engagement with the rubber tire consists of a pawl mounted on the inner clip part which presses against the inner surface of the outer hollow cylindrical clip part under the influence of a spring in order to lock the clip parts together and with the aid of an unlocking cable from it Locking position is releasable.
  • gas spring accumulators as pressure storage elements for the clamp parts of the gripping devices and to attach manual tension cables to the clamp parts pressing their clamping legs against the inside of the tire, with the aid of which they can be moved into their clamped position on the rubber tires.
  • the contact legs of the clamp parts pressing against the outside of the tire are dimensioned in length so that they end above the wheel axis in the applied state.
  • the clamping limbs of the clamp parts pressing against the outside of the tire to protect the wheel rims and any wheel covers at their edges directed towards these should be angled outwards and the clamping limbs of the clamp parts pressing against the inside of the tire should be provided with a crank to increase the guide length in the outer clamp parts.
  • the device developed by the invention has the advantage over the prior art described at the outset that the clamp parts of its gripping devices can be attached very easily and quickly to the rubber tires of the wheels without the actuation of any tensioning screws.
  • the support frames always adapt to the respective wheel diameter and the tire width without the risk of damage to wheel rims or wheel caps. With just as little effort, the gripping devices can later be released from the wheels again, so that overall a much shorter loading or transport time can be achieved than when using conventional devices.
  • the significantly lower weight of the novel device also makes it easier to use in practice, and its simpler construction permits extremely low manufacturing costs.
  • the device for lifting a rubber-tired vehicle 1 which has been described, is composed of several structurally identical support frames 2 which engage the tire circumference of its wheels 3. From these support frames 2, crane ropes 4 lead to the crossbeams 5 of a vehicle crane (not shown), with the aid of which the vehicle 1 can be lifted and transported as a whole or loaded onto a transport vehicle. In another form of use of the support frames 2, it would also be possible to lift the vehicle only on the front or rear wheels in order to be able to move it on the crane hook of a tow vehicle in this state.
  • the support frames 2 shown in detail in FIGS. 2 to 5 are each formed from two support arms 8 which are articulated only in the region of their suspension 6 for the hooks 7 of the crane ropes 4 in the wheel plane. The latter are used to attach them to the vehicle wheels 3 A short distance above the wheel axle 9, the suspension 6, which becomes effective in FIG. 2, is brought into an obliquely downward position, in which gripping devices 10 located at its free end come to rest on both sides of the standing surface 11 of the rubber tire 12 on its tread 13.
  • These gripping devices 10 of the support arms 8 have, according to FIGS. 3 and 4, in each case two clamp parts 14 and 15 which are of essentially hollow cylindrical design. Both are equipped with clamping legs 16 and 17, which press against the inner side 18 or outer side 19 of the tire to grip the rubber tires 12.
  • the clamp parts 15 pressing with their clamping limbs 17 against the inside of the tire 18 are parallel to the wheel axis 9 against the force of a pressure storage element in the clamp parts 14 starting from the support arms 8 and pressing with their clamping limbs 16 against the outside of the tire 19 20 guided longitudinally.
  • the pressure accumulator element 20 which is preferably designed as a gas spring accumulator, is arranged within both clamp parts 14 and 15, as is also a lock 21, which consists of a pawl 22 mounted on the inner clamp part 15, a tension spring 23 acting on it and an unlocking cable 24.
  • the pawl 22 of this lock 21 is pressed under the influence of the spring 23 against the inner surface of the outer hollow cylindrical bracket part 14, which causes a locking of both bracket parts 14 and 15 when the inner bracket part 15 by means of a hand tensioning 25 attached to it so far into the outer Clamp part 14 has been moved in until the rubber tire 12 is firmly clamped between the clamping legs 16 and 17 of the two clamp parts 14 and 15.
  • the actuation of the unlocking cable 24 is required, whereupon the inner clamp part 15 is automatically pushed out of the outer clamp part 14 by the pressure storage element 20.
  • the suspension 6 of the support frames 2 is provided relatively far away from the vehicle wheels 3 by cranking the support arms 8 so that damage to the vehicle body by the crane cables 4 is avoided.
  • the resulting overturning moment of the support frames 2 has been taken into account structurally insofar as the clamping legs 16 of the outer clamp parts 14 pressing against the outside of the tire 19 are dimensioned in length such that they end above the wheel axle 9 when the support frames 2 are in place. Furthermore, these clamping legs 16 are angled outwards at the edges 28 directed towards them to protect the wheel rims 26 and wheel caps 27 of the wheels 3 shown in FIG. 5.
  • the clamping limbs 17 of the clamp parts 15 pressing against the inside of the tire 18 are provided with an offset 29 shown in FIGS. 3 and 4.
  • This measure also forms the prerequisite for the support frames 2 to be able to be adapted to all occurring tire widths.
  • the consideration of different wheel diameters, which is also necessary, does not result in any difficulties anyway, since the support frames 2 can always be adapted to the wheels 3 as a result of the mobility of their support arms 8.
