Claim 1
Independent Claim
119 words
In a vehicle having steerable wheels, apparatus for mounting the wheels on the vehicle, which comprises: a road arm assembly having first and second lateral axes, means mounting said road arm assembly to the vehicle at said first lateral axis, means for pivoting the road arm assembly about said first lateral axis, means for mounting a wheel at the second lateral axis, means for driving said wheel, and means for steering said wheel about a generally vertical axis, said steering means comprising rotatable means mounted along said second lateral axis, king pin means mounted along said generally vertical axis, means for pivoting said king pin means upon rotation of said rotatable means, and means for rotating said rotatable means.
Claim 2
Dependent Claim
119 words
In a vehicle having steerable wheels, apparatus for mounting the wheels on the vehicle, which comprises: a road arm assembly having first and second lateral axes, means mounting said road arm assembly to the vehicle at said first lateral axis, means for pivoting the road arm assembly about said first lateral axis, means for mounting a wheel at the second lateral axis, means for driving said wheel, and means for steering said wheel about a generally vertical axis, said steering means comprising rotatable means mounted along said second lateral axis, king pin means mounted along said generally vertical axis, means for pivoting said king pin means upon rotation of said rotatable means, and means for rotating said rotatable means.
Claim 3
Dependent Claim
45 words
Apparatus according to claim 1, wherein said means for rotating said rotatable means includes: rotatable means mounted along said first lateral axis, and means for rotating said rotatable means mounted along said second lateral axis from the rotatable means mounted along said first lateral axis.
Claim 4
Dependent Claim
101 words
In a vehicle having steerable wheels, apparatus for mounting the wheels on the vehicle, which comprise: a road arm assembly having first and second lateral axes, means mounting said road arm assembly to the vehicle at said first lateral axis, means for pivoting the road arm assembly about said first lateral axis, means for mounting a wheel at the second lateral axis, means for driving said wheel, means for steering said wheel about a generally vertical axis, and means for maintaining said generally vertical axis in a constant attitude As the road arm assembly is pivoted about said first lateral axis.
Claim 5
Dependent Claim
101 words
In a vehicle having steerable wheels, apparatus for mounting the wheels on the vehicle, which comprise: a road arm assembly having first and second lateral axes, means mounting said road arm assembly to the vehicle at said first lateral axis, means for pivoting the road arm assembly about said first lateral axis, means for mounting a wheel at the second lateral axis, means for driving said wheel, means for steering said wheel about a generally vertical axis, and means for maintaining said generally vertical axis in a constant attitude As the road arm assembly is pivoted about said first lateral axis.
Claim 6
Dependent Claim
59 words
Apparatus according to claim 3, wherein said means for steering the wheel includes a king pin assembly and the means for maintaining said generally vertical axis in a constant attitude includes a housing generally enclosing said king pin assembly and means for pivoting said king pin housing an equal and opposite amount as the road arm assembly is pivoted.
Claim 7
Dependent Claim
111 words
Apparatus according to claim 4, wherein said means for pivoting said king pin housing includes: a sleeve portion extending from the king pin housing and mounted concentrically with said second lateral axis of the road arm assembly, stationary gear means mounted along the first lateral axis of the road arm assembly, gear means mounted on said sleeve portion in spaced relationship with said stationary gear means, and middle gear means meshing with both said stationary gear means and said gear means on said sleeve portion, said middle gear means rotating around said stationary gear means in response to road arm rotation and thereby rotating the sleeve portion in the opposite direction.
