Abstract: An exercise machine and transmission for converting first and second rotary inputs into a single rotary output. The machine has a first input shaft, a second input shaft coupled to the first shaft, and a shell. The shafts are mounted to the shell on a common axis, and one-way clutches are disposed between the shell and each respective shaft. The torques of the first and second shafts in one rotational direction are combined in the shell for single output to a load.

Abstract: A transmission system for transmitting power from an engine to the driving wheels of a tractor. The system includes a multiple ratio mechanical range transmission coupled to a speed transmission via a manually operable master clutch. A high slip fluid coupling is used to couple the speed transmission to the engine. The coupling includes a lockup clutch engageable and disengageable under predetermined conditions and sequential order with other clutches.

Abstract: A transmission system particularly useable for transmitting power from an internal combustion engine to the driving wheels of a vehicle such as a tractor. The system includes a multiple ratio mechanical range transmission coupled to a speed transmission via a manually operable master clutch. A high slip fluid coupling is used to couple the speed transmission to the engine, and an electronically controlled lockup clutch locks the impeller of the fluid coupling to the output turbine of same when the speed of the engine exceeds a first predetermined speed, and maintains the coupling locked until the speed of the engine drops below a second substantially lower predetermined speed; the difference between the predetermined speeds is due to a speed comparator hysteresis which serves to prevent hunting during automatic gear shifts between different ratios.

Abstract: A steerable and height adjustable light pod comprising a multi-directional light emitting means is mounted atop a vehicle guide wheel for synchronous angular movement therewith.

Abstract: A transmission system particularly usable for transmitting power from an internal combustion engine to the driving wheels of a vehicle such as a tractor includes a multiple ratio mechanical range transmission coupled to an infinitely variable ratio hydromechanical transmission via a manually operable master clutch. A high slip fluid coupling is used to couple the hydromechanical transmission to the engine, and an electronically controlled lockup clutch locks the impeller of the fluid coupling to the output turbine when the speed of the engine exceeds a first predetermined speed, and maintains the coupling locked until the speed of the engine drops below a second substantially lower predetermined speed.

Abstract: A tractor vehicle (10) is provided with segregated engine (45) and heat exchanger compartments (64). The heat exchanger compartment (64) is supplied with ambient air from an intake grille (24) above the heat exchanger compartment. The process air from the heat exchanger compartment is exhausted forwardly through a front grille (40) location on the tractor. The engine compartment is ventilated by a forced air system induced by the heat exchanger compartment exhaust fan (80). Engine compartment process air is drawn to the downstream side of the primary heat exchanger (76) and is discharged along with the heat exchanger compartment process air, through the front grille of the tractor.

Abstract: An operator's platform, a vehicle cab and a forward tractor engine enclosure are pivotally mounted as a unit at a forward pivot point to a tractor frame. These components are suspended at the rear portion of the frame through an integrated suspension system including a coil spring and a shock absorber. A pair of stationary vertical guide members at the rear of the vehicle interact with adjacent wall guide surfaces of the suspended chassis. These stationary vertical guide surfaces allow the suspended chassis to pivot in a vertical plane around the forward pivot points while controlling lateral movement of the cab relative to the vehicle chassis.

Abstract: Fluid passages machined in the annular brake piston and in the outboard brake ring of a wet disc brake system allows the circulation of cooling and lubricating fluid. An annular disc brake will deliver cooling fluid to the circumferential periphery of the brake disc operating cavity where the fluid relief passages machined in the annular brake piston and in the outboard brake ring will allow the passage of this fluid out of the brake disc operation cavity thus preventing the stagnation of cooling fluid in the brake disc operating cavity.

Abstract: Engine location above or alternatively in front of the front axle of a two axle vehicle provides improved weight distribution in a tractor. Heat exchangers are located amidships with a fan drawing air through the heat exchangers and directing it around the engine. Heated air is directed away from the operator's compartment at the rear of the vehicle. Primary fuel tanks may also be mounted amidships and configured to provide arcuate planar surfaces for directing air borne noise and improving the flow of air to the heat exchangers.

Abstract: Providing a secondary frictional material between a primary frictional material and a backing plate for use in a clutch or brake system having a reaction member which operates in an oil bath, whereupon the consumption of the primary frictional material through contact with the reaction member allows contact between the secondary frictional material and the reaction member. The secondary frictional material is of a composition such that upon motion contact with a reaction member an audible sound is produced.

Abstract: Providing a fluid distribution device for use in a clutch or brake system having a reaction member which operates in a fluid bath whereupon the fluid distribution device after being submerged in the fluid bath tends to distribute fluid peripherally to the reaction member such that fluid is distributed evenly and uniformly to the frictional material integral with the periphery of the reaction member.
