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).

A method and 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. The process may be at least semi-automatically performed, for example under the control of a control unit. 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, and more accurate servicing of a shock absorber may thus be provided.

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.

A vehicle measurement station utilizing at least one displacement sensor disposed on each opposite side of a sensor region of a vehicle inspection lane to acquire displacement measurement data, associated with a moving vehicle passing through the sensor region. Each displacement sensor is configured to acquire measurement data along at least three discrete and vertically spaced measurement axes. A processing system receives the acquired data for evaluation, identification of outlier data points, and for determining a measurement associated with a characteristic of the moving vehicle, such as vehicle velocity, axle alignment, wheel alignment, or dimensions.

A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.
