ABSTRACT OF THE DISCLOSURE
A spacer ring which has an indented reinforcement groove is fastened to the outer rim of a dual wheel of a vehicle. A fastening ring is welded to the inner surface of the reinforcement groove. The outer rim and the spacer ring are pressed against the vehicle wheel rim by a plural-ity of tensioning devices, which are suspended on the fastening ring. The outer wheel is placed against the vehicle wheel in any desired rotational position and coupled therewith with the aid of the tensioning devices, the number of which is adapted to the load on the dual wheel.

DUAL, WHEEL FOR A VEHICLE
FIELD OF THE INVENTION
The invention relates to a dual wheel having one vehicle wheel rim and one outer rim as well as a coupling device disposed between them.
BACKGROUND OF THE INVENTION
Equipping vehicles with dual wheels is known, and it has proved itself in practice as a means for reducing the pressure exerted on the road or other surfaces per unit of area, for improving traction and for increasing reliability on hills. The known coupling devices for connecting the two wheel rims of the two individual wheels as a rule comprise a flange-like screw connection having levers exerting radial tension, which by means of locks are suspended toward the dual wheel on the wheel flange or on special T-rings welded into the deep well of the rim of the dual wheel. The T-rings are welded into the fib at the crossbar The locks are suspended on the upper, flat part of the Trying These coupling devices have the disadvantages that in large vehicles the crossbar of -the T-ring is bent by the heavy load, and that for securing the outer wheel Jo the vehicle wheel, the outer wheel can be coupled only at certain coupling positions.
SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to develop a dual wheel of the genera] type described above which does not have these disadvantages and nevertheless can be manufactured at favorable cost.
This object is attained by providing a spacer ring having at least one indented reinforcement groove on the outer wheel rim, on the inner face of which a fastening ring I`:
is secured. A plurality of tensioning devices is connected with the vehicle wheel rim and suspended on the hastening ring, and these devices press the outer rim and the spacer ring against the vehicle wheel rim. Further advantageous embodiments of the invention are also disclosed herein.
The dual wheel according Jo the present invention has the advantage that the outer wheel can be coupled onto the vehicle wheel in any desired position, so that even heavy wheels can be mounted without effort.
A further advantage is that the tensioning devices can be relatively short, with the result that the spacer ring rotates with the outer wheel only to a very slight extent relative to the vehicle wheel, since the tensioning devices which during this operation describe a correspond-tingly smaller radius, diverge more rapidly away from the fastening ring which is the tangent. This arrangement also contributes to greater stability. - -In one aspect of the present invention there is provided a dual wheel for a vehicle, the wheel comprising 20 inner and outer vehicle wheel rims and a coupling devic e therefore intermediate the rims, a spacer ring intermediate the rims and forming a unit with the outer rim, the coupling device comprising an attachment ring mounting respectively a plurality of clamping devices suspended therefrom for detachably securing to the inner rim characterized in that : the attachment ring is secured to the spacer ring.

BRIEF DESCRIPTION OF TIE DP~AWIN~
The single figure ox the drawing shows a section in the radial direction taken through a dual wheel with the coupling according to the invention.
DESCRIPTION OF THY PREFERRED EMBODIMENT
The dual wheel comprises an outer rim 1, and a vehicle wheel comprising a rim 4 and scintilla dusk The invention coupling 20 comprises a spacer ring 2 welded at weld toga-lion 9 into one shoulder 12 of outer rim lo A plurality of axially effective, releasable tensioning devices 3 disk tribute about the circumference tensions the outer rim 1 against the vehicle wheel rim 4. The tensioning devices 3 are suspended on the side toward the vehicle on eye nuts 5 or weld brackets, which are connected to the wheel disk 16.
.
On the side toward the outer rim l, the tensioning devices 3 are suspended on a fastening ring 6. The fastening ring 6 is welded with a weld seam 8 on inner surface 17 of a reinforcement groove 7 of the spacer rink 2 in such a man-nor that one side of the fastening ring 6 protrudes and forms a free space toward the spacer ring, so that the tensioning devices 3 can be suspended with the tensioning hook 15 on the fastening ring 6. As a result of the pro-vision of the space between ring 6 and the adjacent portion of ring 2 the fastening ring 6 is welded in an endless seam, and the tensioning devices 3 can be suspended at any point on ring 6. The outer wheel can accordingly be coupled to the vehicle wheel at any desired position, since the tensioning devices 3 can be suspended on the fastening ring 6 at the point where the eye nuts 5 are radially at the same level. Even very heavy dual wheels can be so coupled effortlessly, because carrier cams are no longer necessary.
Since no cams at all are provided toward the vehicle for transmitting radial forces, the spacer ring 2 tends to rotate opposite the vehicle wheel when the vehicle is driven under load. The tensioning devices 3 thereupon pull the outer wheel, via the spacer ring 2, still more tightly against the vehicle wheel. As a result of the above struck lure for suspending the tensioning devices on the dual wheel, a high degree of rigidity is attained. Since as a consequence of the particular rigidity no driving cams are required, even heavy dual wheels can be coupled effortlessly, without having to be rotated into any predetermined coupling position.
The reinforcement groove 7, which is produced by means of rolling, for example, serves as an attachment location for the fastening ring 6 and as a reinforcement element for the spacer ring 2. In the case of heavily loaded dual wheels, it is also possible to dispose a plurality of reinforcement grooves 7 on the spacer ring 2, the grooves 121Z40~
being indented either outward or inward.
The number of tensioning devices 3 may be adapted to the expected load on the dual wheel.
The reinforcement groove 7 can also be replaced with a flat steel ring secured to the spacer ring 2, the fasten-in ring 6 then being welded to the flat steel ring in such a manner that a free space makes the suspension of the tensioning hook 15 possible. The reinforcement groove 7 with the fastening ring 6 may also, however, be disposed on the outer rim 1. The spacer ring 2 is welded or screwed to the outer rim 1. As the vehicle begins to move, the outer wheel rotates slightly counter to the inner wheel, which effects a still closer proximity and reinforcement of the two individual wheels.
The tensioning devices 3 are tightened with the aid of the rectangular tube 14, and the tripping distance 10 is adjustable by means of an adjustable bottom spacer 11.
While the invention has been described in detail above, it is to be understood that this detailed descrip-lion is by way of example only, and the protection granted is to be limited only within the spirit of the invention and the scope of the following claims.
