A method and device for balancing a vehicle wheel.

摘要

An electronic wheel balancer intended primarily but not exclusively for front wheels of front wheel drive cars is such that it can be used by a single operator, who operates the engine from the driving seat to drive the wheels and also observes the criteria for balancing the wheels. The front wheels (12) are supported off the ground by supports (15) engaged with the suspension and incorporating force transducers (16). The wheels are provided with marks (21) at a datum rotational position and transducers (19) to indicate when the wheels are in these positions. The phase relationship between the output of each force transducer (16) and the datum position signal is derived electronically and displayed to indicate the angular position for application of balancing weights on the wheel. The value of the required balancing weight is derived from the output of the force transducers. Position and weight signals are displayed on a portable display unit (23).
