A Vickers Model 25M (65) vane motor was chosen for the comparison. This motor is rated for 3000 rpm at 2500 psi maximum pressure. It…
The gear pump design can also be used as a motor. The Hydreco Model 1919 motor has a theoretical displacement of 4.53 in3/rev, a maximum…
An experimental vehicle to harvest whole-stalk sweet sorghum was designed by a university research team. At present, the harvester is a pull-type machine, meaning it…
The hydrostatic transmission, shown in Fig. 6.28, is operating under a constant load. Speed is set by the command voltage at 1000 rpm. The feedback…
The servo pump shown in Fig. 6.27 is like that shown in Fig. 6.26, except a torque motor is used to position the spool of…
Before beginning our discussion of closed-loop hydrostatic transmissions, it is necessary to first learn how a servo-controlled pump operates. A variable displacement axial piston pump…
A configuration where all four wheels are powered is shown in Fig. 6.18. A single pump provides flow to four motors. This machine can be…
The vehicle shown in Fig. 6.17 has three wheel motors supplied by the same pump. In the design of such a vehicle, care must be…
The vehicle shown in Fig. 6.14 has a separate in-line hydrostatic transmission for each drive wheel. The engine delivers power via a universal joint driveline…
