Abstract
A vibration monitor is mounted on a vehicle for monitoring vibrations in the axles and wheels of the vehicle which may indicate some type of failure associated with the wheels. The monitor includes sensors mounted on the axles which are connected to a control box for disabling the vehicle in response to receipt of a vibration signal from the sensors. The control box is arranged to vent the air brake circuit of the truck for applying the brakes of the truck if the control box receives a vibration signal from the sensors having a magnitude which exceeds an acceleration threshold and a duration which exceeds a time threshold determined by the control box. In one embodiment, electrical acceleration sensors are provided which transmit the vibration signals to the control box using an intermittent RF signal having a unique identification signal for indicating which sensor has recorded each vibration signal.
