  • 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.
