Abstract

A clamping plate 30 is disclose for securing the central disc 24 of a wheel 12 to a wheel flange 14 on an axle 16 of an agricultural vehicle. The flange 14 has a plurality of holes regularly distributed about a pitch circle and the central disc 24 of the wheel and the clamping plate 30 have holes aligned with the holes in the flange 14 for receiving bolts 26 by means of which the central disc 24 of the wheel 12 is clamped between the clamping plate 30 and the flange 14. In the invention, the outer diameter of the clamping plate 30 exceeds the diameter of the pitch circle of the holes in the clamping plate by a distance greater than twice the diameter of the bolts 26.

Claims

1. A clamping plate for securing the central disc of a wheel to a wheel flange on an axle of an agricultural vehicle, wherein the flange has a plurality of holes regularly distributed about a pitch circle and the central disc of the wheel and the clamping plate have holes aligned with the holes in the flange for receiving bolts by means of which the central disc of the wheel is clamped between the clamping plate and the flange, characterised in that the outer diameter of the clamping plate exceeds the diameter of the pitch circle of the holes in the clamping plate by a distance greater than twice the diameter of the bolts.

2. A clamping plate as claimed in claim 1, wherein the plate extends radially inwards from the pitch circle of the bolt holes by a distance exceeding twice the bolt diameter.

3. A clamping plate as claimed in claim 1, wherein the part of the clamping plate lying radially within the pitch circle of the bolt holes is reinforced to resist dishing.

4. A clamping plate as claimed in claim 3, wherein the part of the clamping plate lying radially within the pitch circle of the bolt holes is reinforced by forming the clamping plate as a dome of which the convex side faces away from the wheel disc.

5. A clamping plate as claimed in claim 4, wherein the clamping plate is formed as a casting.

6. A clamping plate as claimed in claim 1, formed of one of more sheets of machined steel.
