Abstract
Abstract Driving apparatus for a vehicle having multiple wheels wherein each wheel is equipped with its own, wholly independent driving apparatus operated by either hydraulic or electrical means. The driving mechanism provides power for either driving or braking its associated wheel and it is operable to drive its wheel at a selected one of a number of different speeds or, alternatively, to permit the wheel to rotate freely.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
74 words
Wheel driving apparatus comprising axle means; a wheel journaled on said axle means; a plurality of concentric annular gears fixed to said wheel; rotatable pinion means; means mounting said pinion means for movements into and out of driving engagement with said gears; and shifting means for effecting such movements of said pinion means, said gears said pinion means, said mounting means and said shifting means being located wholly within the confines of said wheel.
Claim 2
Dependent Claim
74 words
Wheel driving apparatus comprising axle means; a wheel journaled on said axle means; a plurality of concentric annular gears fixed to said wheel; rotatable pinion means; means mounting said pinion means for movements into and out of driving engagement with said gears; and shifting means for effecting such movements of said pinion means, said gears said pinion means, said mounting means and said shifting means being located wholly within the confines of said wheel.
Claim 3
Dependent Claim
15 words
The apparatus set forth in claim 1 wherein said shifting means is pressure fluid operated.
Claim 4
Dependent Claim
19 words
The apparatus set forth in claim 1 including seal means secured to said wheel and overlying said annular gears.
Claim 5
Dependent Claim
15 words
The apparatus set forth in claim 1 including motor means for rotating said pinion means.
Claim 6
Dependent Claim
20 words
The apparatus set forth in claim 4 wherein said motor means also is located within the confines of said wheel.
Claim 7
Dependent Claim
13 words
The apparatus set forth in claim 4 wherein said motor means is reversible.
Claim 8
Dependent Claim
23 words
The apparatus set forth in claim 6 including pressure fluid operating means for said motor means and means for regulating said operating means.
Claim 9
Dependent Claim
35 words
The apparatus set forth in claim 1 wherein said pinion means comprises a plurality of pinions corresponding in number to the number of said annular gears and spaced from one another radially of said axis.
Claim 10
Dependent Claim
34 words
The apparatus set forth in claim 8 wherein the spacing between said pinions differs from the spacing between said annular gears whereby only one pinion may engage an annular gear at any one time.
Claim 11
Dependent Claim
34 words
The apparatus set forth in claim 9 including biasing means acting on said pinion means and urging the latter toward a position in which none of said pinions engages any of said annular gears.
Claim 12
Dependent Claim
16 words
The apparatus set forth in claim 8 wherein each of said pinions is of different diameter.
Claim 13
Dependent Claim
134 words
Wheel driving apparatus comprising axle means; a wheel journaled on said axle means; a plurality of concentric annular gears fixed to said wheel; a plurality of rotatable, different diameter pinions; means mounting said pinions for shifting movements of any selected one thereof from a neutral position into and out of driving engagement with a selected one of said gears; means biasing said pinions to said neutral position; shifting means operable to overcome said biasing means and shift a selected one of said pinions into driving engagement with a selected one of said gears; reversible motor means for driving said pinions in a selected one of either of two directions; and means for changing the direction of drive of said motor means regardless of which one of said pinions and gears are in driving engagement.
Claim 14
Dependent Claim
134 words
Wheel driving apparatus comprising axle means; a wheel journaled on said axle means; a plurality of concentric annular gears fixed to said wheel; a plurality of rotatable, different diameter pinions; means mounting said pinions for shifting movements of any selected one thereof from a neutral position into and out of driving engagement with a selected one of said gears; means biasing said pinions to said neutral position; shifting means operable to overcome said biasing means and shift a selected one of said pinions into driving engagement with a selected one of said gears; reversible motor means for driving said pinions in a selected one of either of two directions; and means for changing the direction of drive of said motor means regardless of which one of said pinions and gears are in driving engagement.
Claim 15
Dependent Claim
22 words
The apparatus set forth in claim 12 wherein said annular gear means gears correspond in number to the number of said pinions.
Claim 16
Dependent Claim
15 words
The apparatus set forth in claim 12 wherein said motor means is pressure fluid operated.
