摘要:
A device and method for reducing on-car runout and imbalance in a tire/wheel assembly. An on-car runout device has a powered roller that rotates the tire/wheel assembly while it is mounted on the vehicle hub and a runout measuring device that measures the runout of the vehicle hub and a surface of the tire/wheel assembly. The on-car runout device can operate in combination with an off-car balancer in an integrated balancing system, and a computer determines the optimal position and amount of weights to reduce the imbalance. The on-car runout device also minimizes the runout in a tire/wheel assembly by automatically optimizing the position of the tire/wheel assembly relative to the runout of the vehicle's hub. Additionally, when the on-car runout device communicates with an off-car balancer, the integrated system can calculate the balance weights needed to counteract differences in imbalance forces in the tire/wheel assembly due to changes in the tire/wheel assembly's mounting between the off-car balancer and the vehicle hub.

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 for measuring rotation of the shaft about its longitudinal axis, a vibration sensor operatively connected to the shaft for measuring vibrations resulting from imbalance in the wheel/tire assembly and a motor operatively connected to the shaft for rotating the shaft about its longitudinal axis, thereby to rotate the wheel/tire assembly. A control circuit is also provided for controlling the application of power to the motor. The wheel balancer also includes an assembly for measuring runout of the rim of the wheel/tire assembly, the control circuit being responsive to a rim runout measurement signal to apply power to the motor such that the wheel/tire assembly rotates at a slow, controlled speed during measurement of the rim runout.

A wheel balancing system for the reduction of vehicle wheel and pneumatic tire assembly vibrations with the capacity to determine and selectively adjust the pneumatic tire's pressure simultaneously with wheel balancing. The balancing system includes a drive for rotating the tire and wheel assembly; a sensing system for the selective determination of vibration causation and correction information; a pneumatic system for the adjustment of the pneumatic tire's pressure; a control system for instituting the determined vibration corrections and pressure adjustments; as well as a communication system for receiving, transmitting and presenting data or instructions. The sensing system is responsive to the wheel balancing systems operational status, the wheel and tire assembly's operational status, wireless or network communications and input from the user. The control system includes automatic provisions for safety, convenience, time efficiency, balancing and pressure adjustment. The pneumatic system, under direction of the control system, institutes an automatic adjustment of the tire's pressure; and the communication system includes notification and display provisions.

Matching multiple wheel rims and tires based upon runout and force variation measurements using balancing equipment. Centering errors and mounting errors are also reduced or eliminated. The method includes adjusting the rotational positions of the tires with respect to the wheel rims to compensate for wheel rim run-out and wheel/tire assembly force variations. This is accomplished in one embodiment by sequentially mounting a plurality of wheel/tire assemblies on a spindle of a balancer, measuring the rim run-out for each assembly and the force variations for each assembly, marking each tire of each assembly to identify both the individual tire and the rotational position representing the first harmonic of the tire force variation at which each tire is mounted with respect to its wheel rim, removing each tire from its wheel rim, sequentially mounting the wheel rims with tires removed on the spindle of the balancer, measuring the rim run-out for each rim, and visually indicating to a user a preferred matching between the tires and the wheel rims to minimize assembly vibration.

A wheel balancer and method of mounting a wheel/tire assembly on a wheel balancer are provided. The wheel balancer 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 for measuring rotation of the shaft about its axis, a vibration sensor operatively connected to the shaft for measuring vibrations from imbalance in the wheel/tire assembly and a motor operatively connected to the shaft for rotating the shaft about its longitudinal axis, thereby rotating the wheel/tire assembly. A control circuit and manual input are also included. The control circuit controls the application of power to the motor. The manual input is for requesting the wheel/tire assembly mounting mode, the control circuit being responsive to a request for mounting mode to control the application of power to the motor such as to facilitate mounting of the wheel/tire assembly on the shaft. The method of mounting a wheel/tire assembly on a wheel balancer includes rotating the motor under control of the control circuit at a relatively slow, tire mounting speed, manually placing a wing nut on the threaded portion of the shaft and holding the wing nut in place on the shaft as the shaft rotates, so as to move the wing nut along the threaded shaft.

A wheel balancer includes a shaft adapted for receiving a wheel/tire assembly. The balancer has a longitudinal axis and is rotatable about the axis so as to rotate the wheel/tire assembly removably mounted thereon. A sensor assembly is provided for measuring rotation of the shaft about the longitudinal axis. A vibration sensor assembly measures vibration of the wheel/tire assembly as the wheel/tire assembly is rotated. A motor operatively connected to the shaft rotates the shaft about the longitudinal axis, thereby to rotate the wheel/tire assembly. A load roller applies a generally radial force, which can exceed one hundred fifty pounds, to the wheel/tire assembly during rotation of said wheel/tire assembly. A sensor detects lateral force, wheel/tire assembly radius, and/or wheel/tire assembly diameter, which can have a tendency to cause a vehicle on which the wheel/tire assembly is mounted during use to deviate from a straight line path. A control circuit responsive to the measured vibration of the wheel/tire assembly determines wheel imbalance, and is responsive to the measurement of lateral force, assembly radius, and/or assembly diameter to provide information relating thereto to a user.
