DEVICE FOR DRIVING CRAWLER VEHICLES Russian patent published in 2002 - IPC

FIELD: automotive-tractor engineering. SUBSTANCE: device has steering wheel mounted on shaft. Displacement-following servo drives with control mechanism are connected to turn mechanism of crawler vehicle. Rotating ring is coupled with the steering wheel shaft by means of mechanical transmission unit. Casing is coaxially mounted inside of the ring. External surface of the casing is cylindrical and beveled. Servo drive control mechanism is mounted on the ring and connected to the servo drives by means of flexible pipes. The servo drive control mechanism has control valves and three-armed lever engageable with external casing surface and the control valves. Transducer following movement direction deviations from given direction is connected to driving electric engine via the control unit. The driving electric engine is attached to the casing through mechanical transmission unit. The transducer following movement direction deviations from given direction is designed as satellite navigation system receiver, converting deviations from given crawler vehicle movement direction into electric signal. EFFECT: high accuracy of device operation; wide range of functional applications. 1 dwg
