1. A drive wheel suspension for a vehicle having a body, a pair of laterally spaced driving wheels, a differential securely mounted to the body between the wheels, and a pair of driving axles each having universal joints at its opposite ends connected to the differential and one of the wheels, said suspension comprising a dead axle whose portion inboard of said wheels is of generally rectangular configuration as viewed in plan and spring means for cushioning relative vertical movements of said body and dead axle, said dead axle including two parallel cross-members extending transversely of the vehicle and two wheel carrying members interconnecting said cross-members, said cross-members being spaced apart by said wheel carrying members such that when said wheels are carried by said wheel carrying members one of said cross-members is spaced rearwardly of the differential for freedom of movement in a generally vertical plane relative to the differential and the other of said cross-members is spaced forwardly of the differential for freedom of movement in a generally vertical plane relative to the differential, said rectangularly shaped dead axle being unobstructed between said cross-members and said wheel carrying members to permit said differential to be secured directly to and supported solely by the body whereby said cross-members throughout their extents are free to move vertically relative to said body and said differential.
