One-way Friction Grip Patents (Class 105/128)
  • Patent number: 7930076
    Abstract: A system for reducing wheel sliding on a locomotive is provided for a locomotive including a plurality of axles. The system includes one or more speed inferring systems coupled to each axle to detect rotation of each axle and generate detection signals based upon detecting rotation of each axle. The detection signals include one of speed signals indicative of locomotive speed and non-rotating signals indicative of a non-rotating axle. More particularly, a main controller is coupled to each speed inferring system and is responsive to each detection signal. The main controller identifies non-rotating signals of the detection signals to initiate one or more alert signals of one or more respective non-rotating axles of the plurality of axles. Additionally, the main controller is coupled to an operator panel to alert a locomotive operator of an applied status of a locomotive parking brake in response to the alert signal.
