The traction circuit of the Outcross 9060 machine consists of two closed-loop
circuits, each with it’s own piston (traction) pump, axle motor, and control valves.
The two traction pumps (P1) and (P2) are part of the tandem piston (traction)
pump. Pump (P1) supplies the front traction circuit, and pump (P2) supplies the
rear traction circuit. The tandem, variable displacement, bidirectional piston
(traction) pump is directly coupled to the engine to provide hydraulic flow for
the traction circuits. The swash plate movement for each pump is controlled
separately by a pair of solenoid operated displacement control valves mounted
to the pump (electro-hydraulic servo piston assembly). Pushing the traction
pedal rotates a hall effect sensor that provides an input to the T1: TEC. The T1:
TEC sends a corresponding PWM (Pulse Width Modulation) output signal to the
displacement control valve solenoids to move the pump swash plate accordingly
and control the pump’s output volume (vehicle speed and traction control).
Traction circuit pressure is constantly being monitored at both pumps when
operating in the forward direction. A pair of pressure sensors provide information
to the T1: TEC that is used for traction control.
The vehicle’s direction of travel is controlled by the T1: TEC based on input
from the transmission lever located to the left of the steering wheel. When the
direction lever is in the F (forward) position and the traction pedal is pushed,
solenoid AB-C1 on the front pump and solenoid CD-C1 on the rear pump are
energized. When the transmission lever is in the R (reverse) position and the
