Abstract

An hydraulic transmission for a vehicle such as a car comprises a radial multi-cylinder pump 4 driven by an engine 4 and supplying fluid under pressure via a manifold 7A and a main pressure line 7 to a multi stage turbine 6 adapted to drive the shafts 12 of the rear wheels of the vehicle. The hydraulic fluid is supplied to the pump from a reservoir 5 via a conduit 8. One or more stages of the turbine may be closed off by a valve mechanism, not shown, to increase the output speed. A similar multi-stage turbine may be used in addition to drive the front wheels of the vehicle. <IMAGE>

Description

PROVISIONAL - SPECIFICATION GEARLESS-CAR-VEHICLE THIS INVENTION RELATES TO GEARLESS-CARS-OR VEHICLES The method by which it is to be performed to be particularly described in and by the following statement: According to the Invention, there is provided, a Gearless Car or Vehicle, the means of which, is motivated by Hydraulic-Turbine-Drive, to the Rear Wheels, which can also Drive the Front-Wheels, thereby creating, same, as a Two, and or Four-Wheel Drive-Vehicle.

The main principle of the Design, is provided a Gearless-Drive-Means, to a Vehicle-Car, by way of a means of Fluid-Drive, which consists of a Power Unit (Engine) a Friction-Clutch/or Fluid-Fly wheel, to transmit the PowerS Torque/Drive, of the Engine to a Multi-Cylinder, Hydraulic-Pump-Unit, which in turn transmits the Pressures, from the Pump, to the Multi-Stage-Turbines! Motors, to Drive the Rear, and or, Front-Wheels, and or Both, Front and Rear Wheels, thereby creating same, into a Four-Wheel-Drive-Vehicle.

The Multi-Stage-Turbine/Motors, consist of Sealed Units/Vanes, preferably of equal size and dimensions in say a minimum of Three, to Six, to each Turbine-Unit-Assembly, fitted to take the Drive thro' a Standard Rear, or Front Drive Differentials, as single Drive-Units.

The Fluid-Drive, to each Multi-Stage-Unit is controlled by Manual, or Automatic-Change-Valve-Means, (Not Shown). Firstly, when the Valve-Mechanism, is in the Low position-Setting, all Three to Six, Turbines, take the Full Pressures-Flow, from the Hydraulic-Pump-Unit, ie, the 1st or Low-Speed Position, from 0 to say 15/20 MPH, the 3 to 6 stage Selector/Valve-Gear, Mechanism, then moves into its 2nd Position, Closing-Off, one unit, or stage, of the Turbine-Assembly - thereby increasing speed, to say 20 to 35 MPH, to the 3rd Stage, - Selector, Closing-Off, a further Section, of the Multi-Stage Turbine, to enable same, to Increase Speed to say from 35 to 50 MPH, and then to Final Stage(s) th/5th/6th positions, and Final Tubine-Stage, to Maximum Speed-Range, of say 50 to 70 MPH, Plus, Full-Thrust of the Engine and Hydraulic-Pump-Unit, of up to 2,000/2,500 lbs Per Sq Inch, 10 to 20 gals Per Minute displacement.

The 3 to 6 Stage, Valve-Mechanism /Speed control, Manual, Control, by Small Lever, on Steering Wheel,/the Automatic-Speed-Change, to be controlled by the speed of the Vehicle, at - approx, Pre-Set-Speeds, Per 3 to 6 Stage Turbine(s).

Finally, re the Turbine-Unit/Motor Assemblies, same can be Designed as Duplex-Units, to be fitted Direct to the Axle-Drives of Both Rear and Front Wheel-Drives, as Double-Duplex-Units, in place of the Differentials, Front and Rear Axles, thereby, dispensing with the needs of such Differentials Drive-Units, as each Duplex-Turbine, Drives, one-wheel-only, Port and starboard, Front and Rear, and is in Itself, a Free-Differential-Drive-Unit, Independent of each other, and will compensate each other, as to when a Vehicle Corners, or Vears to Left or Right, etc or can be fitted Direct, to all 4 Wheels,/Hubs, to give the same effect.

The Fluid-Drive/Multi-Stage-Turbines, is Applicable to many other Propulsion/ Transmissions, etc, within the High Technology, Engineering, Fields, Marine/ Aero, and Commercial - etc, where Fluid Power provides a convenient, Rotarymeans, as to same.

The Invention will now be further described by way of Examples, with reference to the accompanying Drawings, in which: Figure 1 Shows the Main Car Chassis, according to the Invention.
