  • Device for detecting different steering angles
    Patent number: 5366042
    Abstract: The invention concerns a device having an originator and a receiver unit (10, 11) and a signal-processing device (17) for detecting different steering angles. The device delivers switch signals, for instance, for actuating differential locks. For identifying discrete steering angles the originator unit (10) operates in conjunction with two sensors (12, 13). The proposed steering-angle sensory analysis is preferably used in axles of tractors and construction machines.

  • Lockable differential gear
    Patent number: 5350340
    Abstract: In a differential, a clutch links an axially stationary planet carrier with an axially mobile output shaft so that they rotate together. Engaging gears with engaging surfaces parallel to the main axis link an axially stationary clutch part with the output shaft so that they rotate together. Engaging gears with engaging surfaces parallel to the main axis link an axially mobile clutch part with the planet carrier so that they rotate together.
