摘要： A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

摘要： An electronic ledger stores vehicle data including a distance travelled by a vehicle wheel assembly during operation and a number of instances of repair of the vehicle wheel assembly. A health status of the vehicle wheel assembly can be determined based on the vehicle data. Transfer of custody of the vehicle wheel assembly from a first entity to a second entity is based on the health status of the vehicle wheel assembly. Data indicating the custody transfer can be stored to the electronic ledger.

摘要： A method and portable apparatus for servicing a shock absorber on a landing gear assembly of an aircraft in a weight-on-wheels state is disclosed. The shock absorber includes at least one chamber containing both hydraulic fluid and a gas in fluid communication with each other. The apparatus includes a source of gas and a source of hydraulic fluid. The amount of hydraulic fluid in the chamber is corrected, preferably such that the chamber is then filled with a known amount of degassed hydraulic fluid. A pre-set mass of gas is then delivered into the chamber under the control of a gas delivery system of the portable apparatus. More accurate servicing of a shock absorber may thus be provided since account is additionally taken of gas dissolved in hydraulic fluid. By delivering a pre-set mass of gas into the chamber, there is no need to rely on a measure of gas pressure or H-dimension (h) when servicing the shock absorber.

摘要： A vehicle inspection apparatus includes: an exciter roller (3) configured to apply vibration to a vehicle (6); a control device 5 configured to control the exciter roller (3); and a vibration setting unit (the control device (5)) configured to set a vibration that is input to a wheel (7) of the vehicle (6) when abnormal noise generated in the vehicle (6) is detected. The control device (5) provides a range of vibrations including the vibration set by the vibration setting unit and applies the range of vibrations to the vehicle (6).

摘要： A portable vehicle alignment system has a vertical central column with a carriage movable along its length, and a pair of camera arms pivotably attached to the carriage, each with a camera pod. The camera pods each have a camera for capturing image data of a respective vehicle-mounted target. One pod also has a calibration target disposed in a known relationship to its camera, and the other pod has a calibration camera disposed in a known relationship to its camera for capturing images of the calibration target. The camera arms pivot between an extended position where the cameras are disposed to capture image data of the vehicle targets and the calibration camera is disposed to capture images of the calibration target, and a folded position where the aligner has a width smaller than the width between the camera pods.

摘要： A bearing temperature sensor system is a temperature monitoring system for wheel hub bearings with data from the system capable of being transmitted to a portable electronic device for subsequent analysis. The system has a plurality of temperature monitoring sensors disposed adjacent non-rotating sections of axle assemblies which wirelessly transmit temperature data to a computer controller system located upon the vehicle being monitored.

摘要： A vibratory weight-on-wheels (WOW) sensing system is provided for use with aircraft landing gear and a wheel coupled to the aircraft landing gear. The WOW sensing system includes a vibration sensor disposed proximate to the wheel and configured to sense vibratory characteristics of a component of the aircraft landing gear and to issue a sensing reflective signal and a processing unit disposed in signal communication with the vibration sensor such that the processing unit is receptive of the sensing reflective signal. The processing unit is configured to analyze the sensing reflective signal to thereby identify that a landing condition is in effect.
