Abstract
An on-road balancing system is provided that includes an analyzer, vibration sensor, and rotation sensor. The rotation sensor is coupled to at least one vehicle wheel and the vibration sensor is coupled to a component within the vehicle. The analyzer is responsive to input from the rotation sensor and the vibration sensor to calculate a phasor quantity representative of vibrations transmitted from the wheel to the component.
Claims19
A method for conducting on-road dynamic balancing, the method comprising the steps of:
- recording base rotation data from at least one rotation sensor coupled to at least one wheel of a vehicle when the vehicle is traveling at about a predetermined speed;
- recording base vibration data from a vibration sensor coupled to a component when the vehicle is traveling at about the predetermined speed;
- calculating a base phasor quantity from the base rotation data and the base vibration data;
- placing at least one weight at a location on the at least one wheel of the vehicle;
- recording offset rotation data from the at least one rotation sensor and offset vibration data from the vibration sensor when the vehicle is traveling at about the predetermined speed;
- and
- calculating an offset phasor quantity from the offset vibration data and the offset rotation data.
An apparatus for conducting off road balancing of wheels of a vehicle, the apparatus comprising:
- an analyzer;
- at least one vibration sensor coupled to a component on a vehicle;
- and
- at least one rotation sensor coupled to at least one wheel of the vehicle;
- wherein the computer is adapted to calculate a phasor quantity representative of vibrations generated by the wheel responsive to vibration data provided by the vibration sensor and rotation data provided by the rotation sensor.
A vehicle comprising:
- an apparatus for performing on-road balancing of a wheel vehicle, the apparatus comprising:
- at least one rotation sensor coupled to the at least one wheel;
- a vibration sensor coupled to a component in the vehicle;
- an analyzer responsive to the at least one rotation sensor and the vibration sensor, the analyzer adapted to calculate a phasor quantity based on data provided by the rotation sensor and the vibration sensor.
