• In the hydrostatic drive truck, power is transmitted to the drive wheels by hydraulic-powered motors, rather than by gears and clutches. The hydrostatic truck’s conventional spark-ignited or diesel engine rotates a hydraulic pump, the “hydrostatic drive pump,” that supplies fluid to two hydraulic motors in the drive axle. Each motor drives a drive wheel.
• The hydraulic fluid is drawn from the same sump that supplies the load handling system. [Incidentally, the pump for the load-handling system (main hydraulic pump) is mounted on, and mechanically driven by, the hydrostatic drive pump.] The hydrostatic drive pump is a variable displacement axial piston pump. Pump output volume and direction of flow are governed by the pump’s swashplate.
• The angle at which the swashplate is tilted controls the length of the piston strokes as the pistons rotate past inlet’outlet ports. Swashplate angle is controlled by an electrical displacement control (EDC).
• The EDC hydraulically varies the angle of the swash plate in response to the electrical signal level received from the computer. The fluid displaced by the drive pump flows through external plumbing to the radial piston drive motors in the drive axle. The volume and direction of the fluid determines the speed and direction of the truck. Each drive motor is connected to an axle shaft that drives an axle end and wheel identical to those used on the standard truck.
• Parallel circuitry to the drive motors allows a speed differential between the motors when the truck is cornering. The diagram below shows the flow of information into and out of the computer that controls the drive system, the SUSMIC DIA 3 microprocessor. The inputs consist of signals from the various sensors and switches that are affected by positioning of the truck’s manual controls.
