Abstract
Abstract Apparatus for driving each wheel of a multiple wheel vehicle comprises a plurality of ring gears mounted on each wheel and gear driving means associated with each wheel for driving the latter independently of or in conjunction with the remaining wheels. The driving means is reversible and includes motor means having a shaft on which is rotatably mounted one driving pinion for each ring gear, the pinion gears being constantly in mesh with their associated ring gears and being freely rotatable relatively to the motor shaft until one or the other pinion is engaged with the shaft. Coupling means is driven constantly by the motor shaft and is operable to be shifted from a neutral position in which neither pinion is driven to a driving position in which one or the other of the pinions is driven.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
Wheel driving apparatus comprising a wheel journaled for rotation; a pair of radially spaced, concentric, annular gears carried by said wheel; a pair of pinion gears; means mounting one of said pinion gears in mesh with one of said annular gears and the other of said pinion gears in mesh with the other of said annular gears; rotatable motor means; coupling means engageable with either of said pinion gears; means mounting said coupling means between said pinion gears for movements to effect coupling and uncoupling of a selected one of either of said pinion gears to and from said motor means; and operating means for moving said coupling means.
Claim 2
Dependent Claim
109 words
Wheel driving apparatus comprising a wheel journaled for rotation; a pair of radially spaced, concentric, annular gears carried by said wheel; a pair of pinion gears; means mounting one of said pinion gears in mesh with one of said annular gears and the other of said pinion gears in mesh with the other of said annular gears; rotatable motor means; coupling means engageable with either of said pinion gears; means mounting said coupling means between said pinion gears for movements to effect coupling and uncoupling of a selected one of either of said pinion gears to and from said motor means; and operating means for moving said coupling means.
Claim 3
Dependent Claim
12 words
The apparatus set forth in claim 1 wherein motor means is reversible.
Claim 4
Dependent Claim
15 words
The apparatus set forth in claim 1 wherein said operating means comprises reciprocable piston means.
Claim 5
Dependent Claim
28 words
The apparatus set forth in claim 1 including means normally biasing said coupling means to a position in which said pinion means is disconnected from said motor means.
Claim 6
Dependent Claim
28 words
The apparatus set forth in claim 1 wherein said coupling means comprises a body having driving lugs movable into and out of notches formed in said pinion gears.
Claim 7
Dependent Claim
