Wheel balancer using wheel rim runout and loaded wheel/tire assembly measurements

摘要

A wheel balancer is provided that includes a shaft adapted for receiving a wheel/tire assembly, the shaft having a longitudinal axis and being rotatable about the axis so as to rotate a wheel/tire assembly removably mounted thereon, a rotation sensor assembly for measuring rotation of the shaft about its longitudinal axis, a vibration sensor assembly for measuring vibration of the wheel/tire assembly as the wheel/tire assembly is rotated, a motor operably connected to the shaft for rotating the shaft about its longitudinal axis, a load roller for applying a generally radial force to the wheel/tire assembly during rotation of the wheel/tire assembly and a sensor for measuring the runout of the wheel rim of the wheel/tire assembly at the bead seat. A control circuit is also included that is responsive to the measured vibration of the wheel/tire assembly to determine wheel imbalance, and responsive to the measurements of wheel rim runout and to the loaded wheel/tire assembly measurement to determine an angular remount position of the tire on the rim to minimize some predetermined uniformity parameter of the tire or wheel/tire assembly.
