Definitions

  • the present invention relates to an auxiliary device for use when mounting car wheels on rotary hubs. It is an almost universal standard that the wheel rims are provided with bolting holes of a conical shape for cooperation with hub portions or mounting bolts of a corresponding conical shape, whereby a centered tighten ⁇ ing of the wheel on the hub carrier can be ensured, which is of course of utmost importance.
  • the invention is based on the consideration that the initial centering of the wheel is not particularly critical, if the wheel is supported in a manner such that it appears as weightless, and on that basis the invention is characterized in that the wheel is mounted on a vertically movable support, which is influenced upwardly by a force corresponding substan ⁇ tially to the weight of the wheel.
  • the wheel mounting on the particular balancing machines will normally be ef ⁇ fected by means of a central nut, without the use of the said conical spanner bolts, but with the use of a cen ⁇ tral cone cooperating with the central hole of the wheel rim such that the same centering accuracy can be ascer ⁇ tained.
  • the wheel is not bound to assume any specific angular position relative the hub, and for that reason the wheel may well roll freely on the support in connection with the horizontal final centering of the wheel.
  • the entire support apparatus may be placed on a horizontal carrier frame, on which it is displaceable towards the mounting hub.
  • the wheels once placed on the carrier plate, can be handled with a minimum of applied force for being moved vertically and horizontal ⁇ ly as required.
  • a support platform for the wheels may be mounted horizontally displaceably at the upper end of an underlying, stationary support structure, this being preferred with equipment for handling large and heavy wheels.
  • Fig. 1 is a perspective view of a balancing appara ⁇ tus provided with a carrier device according to the invention.
  • Fig. 2 is a lateral view of a modified carrier device, and
  • Fig. 3 is a perspective view of a further modified carrier device.
  • a balancing apparatus 2 having in the usual manner a horizontally projecting balancing shaft 4 with an outer mounting head 6 for a wheel 7 to be balanced.
  • the head 6 has contact flange 8 and a cone 10 protruding therefrom, the cone continuing in an outer, threaded pin 12.
  • the wheel 8 has a central hole 14 that can be inserted over the pin 12, whereafter the wheel is mountable on the head ⁇ by means of an outer, non-illustrated nut and an associated washer disc or cup.
  • the cone 10 is designed so as to match the hole 14 for centering the wheel when it is mounted.
  • the shaft 4 is rotated, and the apparatus will then indicate which unbalance there is, whereafter the unbalance can be equalized by means of weight members that are mounted on the edge of the wheel rim.
  • the apparatus is supplemented with a support device for the wheel 8, the device comprising a telescopic post 18, the upper part 20 of which having a top carrier plate 22 for the wheel.
  • the post 18 is placed on a horizontal guiding frame 24 comprising a guiding shaft 26, which is surrounded by a bushing 28 on the post 18, and a rail 30 forming a rol- ling way for a support roller 32 on the post.
  • a compressed air conduit 34 which passes through a pedal valve 36.
  • a vertical air cylinder 38 having its lower end connected to the conduit 34, this further being con ⁇ nected to a relatively large container 40 inside the post 18.
  • the operator can very easily bring the wheel to an approximately correct level and then displace the whole carrier device towards the mounting head 6. During this displacement the operator can effect required small corrections of the height position of the wheel, such that the central hole 14 can easily be placed correctly for its introduction over the shaft pin 12.
  • the wheel After being mounted and balanced the wheel will be correspondingly easy to release from its engagement with the mounting head, and the operator may then actuate a relief pedal 44 on the valve 36, whereby the wheel will be calmly lowered into its lower position, from which it can be taken down or rolled out.
  • valve 36 can be controlled so as to provide just the required air pressure.
  • a similar automatic control can be achieved with the use of a sensor sensing the initial raising of the system, when the pressure is sufficiently high, and thereby causes the supply of compressed air to be stopped at a suitable pressure, which may well be slightly higher than the pressure, at which the initial raising occurs.
  • a support system according to the invention can be used with advantage, so the invention is not necessarily limited to the use here discussed.
  • Another relevant example of use will be the mounting of the finished wheels on the wheel hubs of a motor car or truck, where the invention may be used for a continued mounting of the wheels in an easily movable, 'weightless' condition.
  • the device may be designed such that from the top plate 22 there is a connection down to the ground level, where a plate can then be held for receiv ⁇ ing the wheel and lifting it slightly off the ground or floor.
  • the device may be supported on wheels for easy insertion of the wheel onto the hub, and of course the device will also be usable by the dismounting of wheels or lowering of other heavy objects in an easy, con ⁇ trolled manner.
  • the preferred device shown in Fig. 2 comprises a pressure tank 46, in which there is provided a depending piston cylinder 48 that is open in the bottom and holds an upwardly displaceable piston rod 50 having a lower piston 52 and an upper carrier platform 54 for a wheel.
  • a side stub 56 compressed air can be fed to the tank to such an extent that the lower side of the piston will be permanently exposed to a force which is suitable for raising the platform to a relevant mounting height, when loaded by a car wheel.
  • the air supply conduit passes through a +/- valve 58, such that should the need arise it is possible to adjust the pressure upwards or downwards for adaptation to special wheels.
  • the piston rod passes through a sealing bushing 60, which is provided with a radial connection to an inlet 62 for compressed air supplied from an air source through an on/off valve 64, e.g. a pedal operated valve.
  • the inlet 62 is in open connection with the inte ⁇ rior of the piston cylinder, such that a pressure ap ⁇ plied through this inlet will act on the top side of the piston 52, thus seeking to force the piston downwardly.
  • the conditions are adapted such that by an opening of the valve 64 the piston will be forced down to its bot ⁇ tom position against the action of the air pressure from the surrounding tank, whereby it is possible to move the platform down to a lower position for easy reception of a wheel.
  • the valve 64 is switched to a closing/venting position the air pressure in the tank will be activated for raising the piston rod 50 and therewith the wheel to the desired mounting height.
  • the air pressure in the tank may remain constant, though with the said possibi ⁇ lity of being adjusted by the handling of nontypical tyres, and that the volume of air which is to be let in and out by each operation will be much smaller than with the embodiments in which it is the air pressure in the tank itself which should be built up and relieved, re ⁇ spectively.
  • the invention is not limited with respect to the temporary pressing down of the platform having to be done by means of compressed air, as in principle other means may well be used, e.g. a mechanical rod system or a driving pinion cooperating with a tooth rack on the piston rod; such a pinion can be switched to free rota ⁇ tion when the platform is ready to be lifted.
  • the carrier platform 22 in its lowermost position shall be located in a low height above the floor, such that the wheel can be rolled directly onto the platform and thereafter be lifted to the required height, i.e. with ⁇ out any manual lifting of the wheel.
  • a carrier rail system 70 for the platform 22 being moveably connected with with a floor supported chassis 72 through a pair of parallelogram rods 74, which are pivotal between a lying position and a swung up position, in both positions with the carrier platform 22 disposed horizontally.
  • the pivoting up and down is controlled by means of a cylinder 76, which corresponds entirely to the cylinder 46 of Fig. 2 and is mounted in a lying position between the chassis 72 and and the carrier rail system 70 in such a manner that it can effect the desired pivoting up and down of this system 70 and support the same in the raised position thereof with the said air spring action.
  • the carrying chassis 72 is sup ⁇ ported non-displaceably on the floor surface, while the upper platform 22 is displaceably arranged on the car ⁇ rier rail system 70, such that the desired lateral dis- placeability of the supported wheel is secured anyway. It is deemed unnecessary at this place to explain in more detail why, by the handling of heavy wheels, it is preferable to arrange for the displaceability of the platform 22 at the top rather than at the bottom of the device.

Abstract

Des roues de voiture montées en position verticale sur des moyeux de rotation (6) de machines d'équilibrage de roue, sont guidées jusque dans une position centrée avec précision au moyen de parties coniques coopérantes situées sur le moyeu et sur la roue; cependant l'on observe que le centrage n'est pas entièrement correct puisque la roue à tendance à aller vers le bas du fait de la gravité. Selon l'invention on peut déjouer cet effet en plaçant la roue sur un élément de support (22) d'un appareil auxiliaire (18) adapté pour ménager un amortisseur à air au-dessous de l'élément de support, de sorte que l'amortisseur à air a pour effet d'égaliser la gravité de la roue, de manière que la roue est mobile librement à l'état sans poids, à une certaine distance en haut et en bas. Ainsi, la roue peut être ajustée facilement en hauteur afin de prendre son niveau de montage, et par son serrage final sur les moyeux, la roue est toujours sans poids, de sorte qu'elle peut être centrée avec une haute précision. De plus, l'appareil auxiliaire peut être agencé pour être mobile horizontalement, de sorte que l'on peut également l'utiliser afin d'amener la roue (8) sur les moyeux de support (6). On utilise, de préférence, un amortisseur à air permanent ainsi que des moyens mécaniques (62, 64) afin de presser temporairement vers le bas l'élément de support (22) jusqu'à une position inférieure de réception et d'acheminement des roues.
