    摘要： In a method for advance indication of the possibility of damage occurring to wheel bearings of vehicles, particularly railroad vehicles, the temperatures of the wheel bearing sets of a plurality of wheels are monitored by temperature detectors fixedly mounted on the vehicle. A determined value is derived from the measured values of temperature, and this determined value is compared with the temperature of a further temperature detector, in order to produce a warning signal. The warning system is incorporated in the vehicle itself, and provides a warning to the vehicle personnel.

    摘要： A normally inactive sound signal generator is supported from the rotatable axle of each railway car in a train and actuatable to generate a predetermined signal in response to a hot box condition. Electrically operable signal receivers coupled to electrically operable radio signal transmitters are spaced along the railroad track at predetermined intervals which may be 4,000 to 6,000 feet apart and the receivers and transmitters are operable on low magnitude current, such as provided in the rails of the track for Centralized Train Control Systems. The engine and caboose of a freight train are provided with radio signal receivers actuated by on-board current and the caboose receiver is operative to actuate visual and audible signals as well as an electrically operated air brake dump valve (through a time delay mechanism) and the engine receiver is operable to also actuate visual and audible signals and a relay (through a time delay mechanism) electrically connected to the engine electrical control system for automatically reducing the power output of the engine. If the hot box condition detected is too distant from the actuated track side radio signal generator to receive its low magnitude radio signal, then the low magnitude signal is received by the caboose mounted radio signal receiver as it passes close by the actuated trackside radio transmitter.
