Abstract
A wheel balancer utilizing a novel calibration technique in which the operator must only measure and enter one dimension of the tire. By requiring the operator to measure only one dimension of the tire, the probability of introducing measurement error into the system is reduced.
Claims6
A wheel balancer for balancing a wheel, the wheel balancer comprising:
- a chassis;
- a motor;
- a shaft operatively connected to said motor, said shaft extending from said chassis for mounting a wheel assembly thereto;
- a distal transducer positioned at an offset distance from said wheel assembly, said distal transducer being operative to ascertain first imbalance information;
- a proximal transducer positioned at a known location relative to said distal transducer, said proximal transducer being operative to ascertain second imbalance information;
- a processor operative to determine an imbalance characteristic of said wheel assembly derived from said first and second imbalance information;
- and
- said processor being programmed to implement a calibration sequence that determines at least one calibration constant utilizing only one physical dimension of said wheel assembly as entered by a user.
