Abstract
Abstract A fluid motor which is particularly constructed for mounting a driven member substantially concentric thereto with the driven member being preferably in the form of a vehicle wheel although the motor can drive other elements such as pulleys, shafts, etc. One of the principal features of the fluid motor is the arrangement of the components thereof, the use of fluid bearings throughout, and fluid thrust bearings particularly adapted to accommodate axial thrusts, such as those imposed by a vehicle wheel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A fluid motor, said fluid motor being of a construction particularly to be fixedly secured to a support at an inner end and have a concentrically disposed driven member coupled to an outer end, said motor including a stator and a case adapted to be fixedly mounted, a rotor mounted within said case and supported by said stator for rotation about said stator, said rotor having a plurality of radiating cylinders formed therein with each cylinder having a piston disposed therein, said case including a race member having an internal raceway engageable by said pistons and cooperating therewith to effect rotation of said rotor, and a drive plate coupled to said rotor at one end thereof for rotation therewith and for cooperation with said case to seal said motor at said outer end, said drive plate being primarily disposed within said case and having means thereof for mounting a wheel and like members.
Claim 2
Dependent Claim
153 words
A fluid motor, said fluid motor being of a construction particularly to be fixedly secured to a support at an inner end and have a concentrically disposed driven member coupled to an outer end, said motor including a stator and a case adapted to be fixedly mounted, a rotor mounted within said case and supported by said stator for rotation about said stator, said rotor having a plurality of radiating cylinders formed therein with each cylinder having a piston disposed therein, said case including a race member having an internal raceway engageable by said pistons and cooperating therewith to effect rotation of said rotor, and a drive plate coupled to said rotor at one end thereof for rotation therewith and for cooperation with said case to seal said motor at said outer end, said drive plate being primarily disposed within said case and having means thereof for mounting a wheel and like members.
Claim 3
Dependent Claim
82 words
The fluid motor of claim 1 wherein said rotor has fluid thrust bearings at the opposite ends thereof to compensate for axial thrusts thereon, and said fluid motor is particularly adapted to have a wheel carried thereby and the fluid thrust at the inner end of said rotor is greater than the fluid thrust at the outer end of said rotor to compensate for axial thrust during the turning of a vehicle of which said hydraulic motor is to be a part.
Claim 4
Dependent Claim
28 words
The fluid motor of claim 2 wherein said fluid thrust differential is at least in part effected by venting the case at the outer end of said rotor.
Claim 5
Dependent Claim
33 words
The fluid motor of claim 2 wherein said fluid thrust differential is at least in part effected by providing a special thrust surface at the inner end of said rotor adjacent said stator.
Claim 6
Dependent Claim
118 words
The fluid motor of claim 1 wherein all bearings of said motor are fluid bearings, and said rotor has fluid thrust bearings at the opposite ends thereof to compensate for axial thrusts thereon, fluid under pressure from said fluid bearing between said rotor and said stator escaping axially to the ends of said rotor and forming said fluid thrust bearings, and said fluid motor is particularly adapted to have a wheel carried thereby and the fluid thrust at the inner end of said rotor is greater than the fluid thrust at the outer end of said rotor to compensate for axial thrust during the turning of a vehicle of which said hydraulic motor is to be a part.
Claim 7
Dependent Claim
37 words
The fluid motor of claim 1 wherein said case includes an outer end plate; said stator, said race member and said end plate all having aligned and joined together outer peripheral portions cooperating to encase said rotor.
Claim 8
Dependent Claim
32 words
The fluid motor of claim 1 wherein a fluid flow control manifold iS positioned entirely within said stator and is coupled thereto for delivering fluid to and removing fluid from said stator.
