DEVICE FOR MOUNTING OR DISASSEMBLING A WHEEL

5

The present invention relates to a device for mounting or dismantling a wheel of a vehicle on resp. of a wheel axle of that vehicle. More in particular, the present invention relates to such a device, which is particularly suitable for relatively large and heavy wheels to be mounted and dismantled, such as the wheels of a city bus, an agricultural vehicle, a truck, etc.

In particular for such relatively large and heavy wheels to be mounted / dismantled, to the best of our knowledge no suitable device is available in the art, as a result of which it is still necessary to manually mount or dismantle such large, heavy wheels. Precisely because of the weight and size of these large wheels to be mounted / dismantled, mounting or dismantling thereof is often a job that can only be carried out with at least two employees. Even then it concerns one. very labor-intensive activity, whereby muscle strength must be ensured that the wheel to be mounted / dismantled comes from or off the wheel axle. That in itself is difficult enough, but is further complicated when mounting a wheel, because holes in a wheel must be correctly aligned with pieces of threaded rod at the end of the wheel axle. Those pieces of threaded rod must be inserted through the holes, after which bolts must be screwed over them to mount the wheel. It is clear that, precisely because of the weight and the large size of the wheels to be mounted / dismantled, this is a laborious and time-consuming task. The present invention contemplates 1025438

to remedy the disadvantages of the known technique or at least

to be considerably reduced, for which a device is I

provided for mounting or dismantling a wheel of I

a vehicle comprising one in at least one direction of I

movable platform, which forms a bearing surface for the wheel. I

By placing the wheel on the platform and then I

move to the wheel axle, which is a movement that crosses I

can be moved very easily from the platform, preferably I

also in the rolling direction of the wheel, such as with I

15 swivel wheels, which are mounted lightly, it is possible to use the I

the plateau in the rolling direction at the contact between I

the platform and (the tire of) the wheel are pushed away and the I

wheel to be mounted / dismantled itself essentially stationary I

invention. I

In a preferred embodiment, at the plateau I

natural rolling direction of a to be mounted or dismantled I

wheel. I

Furthermore, a support for the wheel to be mounted / dismounted may be mounted on a plateau at one side thereof, at least in use condition. This ensures that the wheel to be mounted / dismantled remains upright on the platform, because the wheel can lean against it. By the expression "at least in a position of use" is meant that the support can be demountable or, for example, can be foldably connected to the platform via a hinge. This has a favorable effect on the amount of space required for a number of such devices. devices, for example during transport from a production facility to a dealer.

In an embodiment in which the platform has a width corresponding to large, wide wheels to be mounted / dismantled, it may be favorable that such an embodiment comprises: an additional support for releasably to be arranged on the platform spaced from the side. Such an additional support serves to make the device with a relatively large width platform suitable for use with relatively narrow wheels to be mounted / disassembled, the platform of the device not having to protrude far below the vehicle, where often a (hydraulic) jack. In this way it is prevented that the jack and the device in the case of use for relatively narrow wheels to be mounted / dismounted are in each other's way, wherein the device cannot be moved far enough to the wheel axle about the wheel from and to the wheel axle. to dismantle and assemble.

The platform can have a width corresponding to small, narrow wheels to be mounted / disassembled, and in such a case can comprise: an additional platform detachably connected to the platform. Thus, an embodiment of a device purchased for 1025488 is

(for example incidental) use with considerably wider te I

a state connected to the plateau in at least one I

direction to and from a wheel axle of the vehicle over an I

movable surface. Thus, optimum mobility is I

provides, even in the case that the extension of the I

10 additional plateau is used. To this end included in I

the additional platform preferably comprises at least two castors, I

again for random movement over the surface. I

Because a plateau must rest on at least three points in order to I

to be able to carry a weight effectively, and the additional I

15 at least two such support points in the form of I

has the castors, the connection with the platform I ensures

itself for the at least third focal point of the supplementary I

plateau. I

Furthermore, the plateau can have a greater length than I

of the wheel axle to which it must be mounted. This has I

the advantage that when the central main I

4 4 5 of the plateau in the rolling direction can be used to also bring about the alignment of the studs and the holes.

The means for moving the platform can furthermore comprise wheels which are arranged substantially on the side of the platform. In such an embodiment, the height of the platform above the base over which the platform must be movable can be minimized.

The vehicle itself, on the wheel axle from which a wheel is to be mounted, can therefore only have to be lifted a minimum distance, or higher, for example with a jack, to be able to mount and dismantle wheels effectively. For this purpose use can be made of extensions extending substantially in upward direction relative to the plateau for mounting beneath wheels, in particular swivel wheels. This is an elegant and simple way to achieve mobility in all directions.

Preferably, means for moving the platform comprise a block or brake to easily roll the wheel to be mounted or dismantled on or off the platform, without the platform rolling away or sliding.

The invention will be explained in more detail below with reference to a number of exemplary embodiments thereof, which are shown in the accompanying drawings, in which the same or similar components are designated with the same reference numbers, and in which: Fig. 1 shows a perspective view of a device according to the present invention in use for mounting / dismantling a relatively large and heavy wheel 30 on a wheel axle; Fig. 2 shows a perspective view of a first alternative embodiment of a device according to the present invention; and 1025488

Fig. 3 shows a perspective view of an I

second alternative embodiment of a device I

according to the present invention. I

In Fig. 1, a device 1 according to the present I

5 the invention. The device 1 is in use around a wheel I

2, around which a band 3 is wrapped, mounted or mounted

disassembling a wheel axle 4. The wheel axle 4 is attached to the I

end thereof a wheel plate 5, which as a kind of flange on I

the end of the wheel axle 4 is designed. From the I

Wheel plate 5 projects a number of pieces of threaded end 6. The I

wheel 2 must be mounted against or dismantled I

of the wheel plate 5, the pieces of threaded end 6 being 1

must be inserted through holes 7 in the wheel 2, or there I

must be removed from. For the sake of simplicity I

The description below is based on an I

situation of use where the wheel 2 has to be mounted I

on the wheel axle 4 and more particularly on the wheel plate 5, I

the pieces of threaded end 6 having to be inserted through the I

holes 7 in the wheel 2. For dismantling a wheel 2 I

20 reverse considerations apply. I

The device 1 comprises an I formed by a grid 8

plateau, around which a tubular frame 9 of hollow, in I

section is rectangular, in particular square tubes, I

applied. There are four I at the corner points of the tube frame 9

25 L-shaped plate elements 10 arranged in I

forming substantially upwardly extending extensions of the I

platform formed by the grid 8 and the tubular frame 9. To I

the underside of the horizontal leg of the plate elements I

10, in each case, a lockable swivel wheel 11 is provided for I

Movement of the device 1 over the substrate 12, which I

is preferably a piece of road surface or the like. The L-I

shaped plate elements 10 therefore allow I

castors 11 are used, which have a specific I

102548a | 7 have a mounting height, while the platform 8, 9 is located as low as possible above the base 12.

It has already been noted that the castors 11 can be locked. This is preferably the case for at least one and more preferably two of the swivel wheels to prevent the device 1 from moving away, slipping or rolling away when a wheel 2 to be mounted / dismantled is rolled on or off the platform 8, 9. In the case of swivel or other types of wheels, a block or brake can be provided which is preferably selectively energized to make the means for moving the platform blockable.

The platform 8, 9 is intended as a bearing surface for the wheel 2, which rests on it. The wheel 2 is held upright with the aid of a bow-shaped support 13 at two of the plate elements 10, which for this purpose are provided with a foot 14, into which the bow-shaped support 13 is inserted. The bracket-shaped support 13 can thus be removed from the feet 14, of which only one is shown here. For the sake of rigidity, the bracket-shaped support 13 can be secured in the feet 14 with the aid of a thru axle, split pin, bolt / nut assembly or the like (not shown here).

As already noted above, the platform 8, 9 forming a bearing surface is located low above the base 12. For a center line adjustment of the wheel axle 4 and the wheel 2, use can be made of a jack (not shown) to adjust the wheel axle 4 in height in the direction of double arrow A.

The operation is as follows.

The device 1 with the wheel 2 on it is moved over the pivot wheels 11 to the wheel axle 4. Rolling wheel axis 4 and the wheel 2 in particular are taken into account. If the device 1 with the wheel 2 thereon the wheel axle 4 and more particularly the wheel plate 5 1025488 Η

approaching the pieces of threaded end 6, a single I

user rotate the wheel 2 in the direction of double arrow I

B, to align the holes 7 in the rim of the wheel 2 with I

the pieces of threaded rod 6 on the wheel plate 5. If desired, I

5 a further adjustment of the height of the wheel axle 4 I

are performed using the (not shown and I

possible hydraulic jack. Due to the large weight I

and the size of the wheel 2 will turn in the I upon rotation thereof

direction of arrow B, in particular if the castors 11 I

10 roll very lightly, the wheel 2 per se remain stationary, I

so that the alignment of the wheel axle 4 with respect to the wheel I

2 is preserved, and with alignment of the pieces I

threaded end 6 relative to the holes 7 can be I

effected, because then the device 1 under the wheel 2 I

15 slides or rolls in the rolling direction of the wheel 2 at the I

contact between the wheel 2 and the platform 8, 9, that is I

indicated by double arrow C. Therefore, a simple I

alignment of the studs 6 and the holes 7 become I

accomplished. I

As noted above, the bracket-shaped I

support, which in the embodiment shown in Fig. 1 is I

inserted into feet 14, be detached from feet 14. I

This promotes the transport possibilities of a number I

devices 1, which then take up less volume and I

25 are easier to stack. As an alternative to the feet I

14 other solutions can therefore also be considered, I

which are within the reach of the average skilled person, I

such as lockable hinges, etc. It is also possible I

use within the scope of the present invention

30 making a plateau 8, 9 that is not on four but only on I

3 support points (castors 11) have contact with the I

substrate 12. In any case, casters 11 deserve the I

preference with regard to random mobility I

1025488 | 9 over the substrate 12, and the self-orientating capacity of swivel wheels also ensures that rotation of the wheel 2 in the direction of double arrow B is converted into a displacement below the wheel 2 to be mounted / dismantled by turning the device 1 into the direction of double arrow C. In any case, 11 alternatives are also conceivable for the castors, such as roller balls, etc.

Fig. 2 shows an alternative embodiment of the present invention. In principle, it concerns the same device 1 as that shown in Fig. 1. In Fig. 2, however, the bracket-shaped support 13 is fully shown, as are the two feet 14, into which the bracket 13 is inserted, and split pins or locking pins 15 are also shown to fix the bracket-shaped support 13 in the feet 14.

An additional bracket-shaped support 16 is also shown, against which a platform narrow wheel 17 formed at the contact point (s) 18 rests relative to the width of the platform formed by the grid 8 and the tube frame 9.

The additional bracket-shaped support 16 is mounted on the grid 8 by means of bolt-nut couplings 19.

This shows the effectiveness of the grating 8, in that bolts of the bolt-nut couplings 19 can be fitted through the grating 8 at any position, whereby the width of the tire 17 to be mounted / dismounted in can be taken into account in the direction of arrow D. When, in fact, the device 1 is displaced laterally in the direction of arrow D, the additional bow-shaped support 16 ensures that the swivel wheels 11 shown on the right-hand side in Fig. 2 are not far below the vehicle. , to which the wheel 17 must be mounted, will protrude where these could be impeded by the presence of a jack (not shown).
