Theoretically, if the "B" end of the hydraulic transmission illustrated were provided with a variable position tilting box, and the "A" end displacement were to be constant, the __________. See illustration GS-0057.
• Hydraulic transmission with axial-piston pump and motor – how tilt-box angle affects piston stroke and displacement • Relationship between displacement, flow, and speed for the B-end hydraulic motor when A-end flow is fixed • Difference between speed (rpm) and horsepower/torque in a hydraulic system with constant input power
• If the A-end pump displacement and speed are constant, what does that say about the flow rate and input power being sent down the high‑pressure line? • On the B-end motor, how does changing the tilt‑box angle change its displacement per revolution and therefore its rpm for a given flow? • With essentially the same hydraulic power available from the A-end, what must happen to torque vs. speed at the B-end as its displacement is increased or decreased?
• Be clear on which end is acting as the pump (A-end) and which is the motor (B-end) in the illustration • Think about what happens to B-end speed as its displacement (tilt‑box angle) approaches zero stroke versus when the angle is increased • Separate in your mind the behavior of speed (rpm) from available horsepower/torque; make sure the option you choose keeps overall power balance physically reasonable
