The present invention concerns a wheel rim and a method for making a wheel rim of the type suited for use on an agricultural or construction vehicle. The new feature of the wheel rim according to the invention is that the central hub plate at the outer periphery includes a number of tabs extending away from the centre of the central hub plate, where the second hub plate at its inner periphery also includes a number of tabs extending towards the centre of the hub plate, where the tabs have a geometric shape such that the tabs fit between each other, where the tabs include holes arranged at the same pitch circle diameter and at right angles to the tabs. In connection with the making of the hub plate, the second hub plate and the central hub plate can be produced from a single piece of suitable material, preferably steel plate, as the mentioned tabs extend over each other when two parts are separated and turned such that the tabs come to lie upon each other. The two hub plate parts are then joined by bolts in the holes formed in the mentioned tabs. |

1. A wheel rim of the type suitable for use on an agricultural or construction vehicle, wherein the rim includes a rim ring for mounting a tyre and further including an at least two-part hub plate extending inside the rim ring, where the at least two-part hub plate includes a central hub plate including a number of holes and a contact surface for mechanical and detachable securing to a hub on a vehicle, wherein the central hub plate includes holes on a contact surface at the outer periphery for joining with a second hub plate with an inner periphery and an outer periphery, wherein the second hub plate at the inner periphery includes a contact surface with corresponding holes for joining with the central hub plate, where the second hub plate at the outer periphery includes holes for direct or indirect joining with the rim ring, characterised in that wherein the central hub plate at the outer periphery includes a number of tabs extending away from the centre of the central hub plate, that the second hub plate at its inner periphery also includes a number of tabs extending towards the centre of the hub plate, that the tabs have a geometric shape such that the tabs fit between each other, the tabs including holes arranged at the same pitch circle diameter and at right angles to the tabs. |
