AUXILIARY PROPELLING DEVICE FOR THE 155MM HOWITZER CARRIAGE, M1A2
CONSOLIDATED DIESEL ELECTRIC CORP STAMFORD CONN
A prototype auxiliary propelling system was developed which embodies, in concept, a hydrostatic transmission utilizing variable displacement reversible flow hydraulic pumps, and fixed displacement reversible motors. The system, as designed, does not impair the function of the weapon achieves minimum weight with compactness utilizes modular construction for field mobility, portability and provides quick field installation and maintenance. The drive system utilizes the extreme weight of the weapon as an asset rather than a liability in achieving traction. The system consists of a hydraulic power package, two lightweight wheel drive gear boxes, and two hydraulic lines. The system utilizes Continental Engine Model 4A084-1 as the power source. An integrated mechanical computer in the control unit permits differential motion to the drive wheels allowing turning on any radius down to zero degrees. The hydraulic wheel drive system has numerous applications for both commercial and military equipment. Author
