Description of invention
The invention relates to a wheel specifically adapted for use on tracked vehicles, and in particular although not exclusively to use on military tracked vehicles, where the wheel is substantially T-shaped in cross section from the centre to the rim.
Tracked vehicles include a large number of wheefs, as each track requires a plurality of pairs of wheels, which run inside the track. These are usually referred to as "road wheels" although they run inside the track rather than directly on the road or other ground surface. To retain the track correctly aligned around the wheels, some or all of the track sections include centre guides, and one wheel of each pair runs on each side of the centre guides. The face of each wheel that is adjacent the centre guides often rubs on the centre guides and thus suffers wear.
Some such wheels are substantially T-shaped in cross section from the centre to the rim as this is a shape which provides advantages in particular in terms of weight. However, they do also suffer from some disadvantages relating to the difficulty of manufacture and the strength of the wheel rim.
In order to reduce the wear suffered by such wheels various forms of wear elements have been incorporated into the wheels, For example, the main bodies of such wheels are often cast from aluminium, and it is known to include wear elements of a more wear resistant materia!, such as steel, as inserts when casting the main bodies. Other known methods of providing a wear element are to spray a second metal onto the main body of the wheel around the inner edge of the rim, or to rivet a wear element in place. However, all of these options require the wheel to be returned to a factory for
refurbishment when the wear element needs replacement, which is less than idea! when the vehicle is in active service. Furthermore, none of these options contribute significantly to the strength of the wheel, which it would be advantageous if they did.
It is an object of the present invention to provide a wheel specifically adapted for use on tracked vehicles, which is substantially T-shaped in cross-section from the centre to the rim, which obviates the above described problems and which, when it is suffering from wear, can preferably be refurbished without being returned to the factory.

The inner edge of the rim preferably includes a formation to assist in correctly locating the wear element when securing it to the inner edge of the rim and retaining it in place during use. The formation may be a Hp or a recess.
The wear element may include a formation to co-operate with the formation on the inner edge of the rim.
The wear element may be a single piece which extends around the inner edge of the rim, or it may be a plurality of pieces which combine to extend around the inner edge of the rim.
The wear element may be made from steel, and the main body may be made from aluminium.
According to a second aspect of the present invention there is provided method of making a wheel specifically adapted for use on tracked vehicles comprising the steps of: a) forming a main body which is substantially T-shaped from the centre to the rim, the main body including a rim with a circumferential surface, an inner edge and an outer edge, the inner edge in use facing centre guides of the track; b) forming a wear element; c) applying a locking compound to the inner edge of the rim; d) putting the wear element in place on the inner edge of the rim, and e) securing the wear element to the inner edge of the rim by threaded fasteners.
According to a third aspect of the present invention there is provided a wheel and track assembly specifically adapted for a tracked vehicle comprising a track having a plurality of track sections some or a!l of which include centre guides and a plurality of wheels according to the first aspect of the invention or made according to the second aspect of the invention.

This assists in locating the wear element 28 accurately in piace during the process of securing it to the rim 14 and furthermore assists in retaining the wear element 28 in place during use of the wheel 10, as it is keyed to the rim 14.
Before the wear element 28 is secured to the rim 14 either or both of the wear element 28 and the inner edge 16 of the rim 14 is coated with a locking compound, as appropriate for the compound used. Then the wear element 28 is put into piace on the inner edge 16 of the rim 14 and secured there by means of the threaded fasteners 26. Doing this means that the wear element 28 is more resistant to displacement from its correct position than would otherwise be the case. It also means that, if the wear element 28 is formed of a strong material, such as hardened steel, the presence of the wear element 28 contributes to the structural performance of the wheel 10.
In use each road wheel R on a tracked vehicle is a wheel 10, and the wheel 10 is oriented such that the wear element 28 is facing the centre guides C of the track. As the vehicle is used the centre guides C will contact the wear elements 28 on the wheels 10 and over time those wear elements 28 will be worn down. When a wear element 28 is worn and needs replacing the wheel 10 may not need to be returned to a factory or the like for refurbishment. Rather, it may be possible for the old wear element 28 to be removed and replaced quite simpiy by maintenance staff using the maintenance facilities routinely available to them.
