30 -- TEST STAND FOR X1100-3B CROSS-DRIVE TRANSMISSION SOL CBD&&&-9909-0002 DUE 100499 POC Fran Malinowski 256-235-4256 Yvonne S. Land 256-235-7559 Anniston Army Depot is seeking a Rough Order of Magnitude (ROM) price from companies that can provide a test stand capable of functional testing of the X1100-3B cross-drive transmission in accordance with Depot Maintenance Work Requirement (DMWR)9-2520-276. The test stand will be located at Anniston Army Depot, Anniston Alabama, and will be designed, fabricated, and installed by the supplier with all functions, capabilities and equipment as described herein. The contractor shall provide the resources necessary to design, manufacture, install, calibrate and demonstrate the functional operation of one (1) transmission test stand. The test stand shall be designed to provide comprehensive vehicular simulation for precise and smooth speed control, rapid acceleration upshifts, gradual acceleration upshifts, continuous full speed operation, full throttle load induced downshifts, closed throttle downshifts, full speed reverse operations, and stall tests on both new and rebuilt X1100-3B transmissions. The X1100-3B hydrokinetic transmission is fully automatic and consists of a torque converter with an automatic lock-up clutch in combination with a four speed planetary range package for propulsion. Hydrostatically controlled variable ratio differential steering is superimposed on the outputs through combining planetaries. Oil cooled brakes of multiple plate construction, integral to the transmission, provide vehicle braking. The three-element high capacity torque converter extracts and multiplies the characteristic high rise torque of the AGT-1500 turbine engine and transmits it to the range package. This combination of high converter capacity and high engine torque provides the desired acceleration, steering, and efficient operating characteristics. Under most conditions, a lock-up clutch is automatically engaged to bypass the converter and provide direct mechanical transmission of power. The ability to operate more efficiently in lock-up under a greater percentage of conditions is a direct benefit of the high torque provided by the turbine engine. The range package, consisting of five multiple-disc clutch packs and three planetary gear sets, provides four forward and two reverse ranges (drive ratios) in a compact arrangement. The transmission control system is designed to provide protection from overspeed caused by multiple downshifts, through provision of a back-up signal from the lock-up governor, in event of shift governor failure. In addition, inhibited upshift points in both forward and reverse are set at a speed higher than the normal upshift but lower than the engine governed speed to ensure that a forced upshift occur should the normal upshift not occur. Downshifts and forward/reverse shifts are also inhibited to preclude selection of an incorrect gear range. Transmission range control is achieved by receiving electrical signals to provide the following modes of operation: Low/Automatic First, Second, Third, and Fourth; Drive/Automatic Second, Third, and Fourth; Neutral/Pivot Steer; Reverse/Automatic First and Second. X1100-3B Transmission Characteristics are as follows: Dimensions-length is 40.8 inches, width is 62.0 inches, and height is 36.1 inches; Dry Weight is 4340 pounds; Maximum Gross Input Power is 1500 HP @ 3000 RPM;Maximum Net Input Power is 1400 HP @ 3000 RPM; Maximum Net Input Torque is 3250 ft-lbs. Drive Ratios: First is 5.877:1; Second is 3.021:1; Third is 1.891:1; Fourth is 1.278:1; Reverse-1 is 8.305:1; and Reverse-2 is 2.354:1. Operating Input Speed Range is 850 RPM to 3200 RPM. Steer Ratios: First is 2.34:1; Second is 1.52:1; Third is 1.30:1; Fourth is 1.19:1; Reverse-1 is 3.51:1; and Reverse-2 is 1.38:1. Braking (Brake apply shafts): 1 Hydraulic and 2 Mechanical. Oil Capacity: 40 Gallons @ 205-245F. Test Equipment Requirements: Provisions shall be made for an input drive with the capability to transmit the following: 1) Input torque of 0-3000 lb-ft; 2) Input speed of 800-3000 rpm; and 3) Maximum inertia of input drive shall be 5.4 lb-ft-sec2. Provisions shall be made for connecting the output shaft to a loading device capable of absorbing full load. Also provisions shall be made for connecting steering control, mechanical brake control, hydraulic brake control, pressure and temperature outlets, oil lines, and installation of right and left brake cavity observation covers. An oil line shall be connected from the fan drive lube port to the left hand fan drive drain port. This oil line shall include a shut-off valve near the lube port. In addition, provisions shall be made for range selection, simulated engine compressor discharge pressure (CDP), electrical signals and mechanical brake electrical interface with transmission main harness connector and mechanical brake warning light connector.
