A wheel assembly according to claim 1 in which each drive dog is resiliently mounted on the wheel by means of at least one rubber element disposed between the drive dog and the wheel.
Claim 6
Dependent Claim
51 words
A wheel assembly according to claim 1 in which the ends of the drive dogs adjacent the disc portion of the wheel are each mounted on the wheel by means of a spigot arranged to enter a rubber bush mounted in a socket formed in the disc portion of the wheel.
Claim 7
Dependent Claim
72 words
A wheel assembly according to claim 1 in which the ends of the drive dogs remote from the disc portion of the wheel are each mounted on the wheel by means of a rubber shear mounting comprising a central metal block, secured to the rim portion of the wheel and a pair of outer rubber blocks bonded to the metal block and drive dog one on each side of the metal block.
Claim 8
Dependent Claim
56 words
A wheel assembly according to claim 6 in which the drive dogs are of a generally rectangular channel section with the open side of the channel facing the rim portion of the wheel and the rubber blocks of the shear mounting are bonded to the inside faces of the substantially radially extending walls of the channel.
Claim 9
Dependent Claim
64 words
