Wheel Balancing (tyres)

Fa. Weimbs Düren


Wheel balancing is described as the compensation of unequal weight distribution in a rotary component. With the crankshaft this is done, e.g., by the drilling of holes, with the car wheel, by the placing of weights opposite to the heaviest point. With particularly free running bearings, static imbalance can be determined by the pendulum method, without the use of other devices. With the correct amount of counter-weight, the wheel comes to a stillstand in any position. Dynamic imbalance describes unequal weight distribution on varying wheel levels, which only becomes noticeable by the wheel wobbling at higher speeds. In this case a balancing machine is necessary to determine the amount of counter-weight. Dynamic balancing is always done first. It is almost impossible to balance a wheel simpler and faster than with the above shown machine. Neither the wheel-breadth nor any measurements must be entered. Through a universal stub, almost every wheel can be mounted in a few seconds. After calibration by scanning arms, a test run is necessary, thereafter it is almost impossible to make a mistake with the mounting, except if the adhesion point hasn't been properly cleaned beforehand.


The simple use of this balancer is due to the two aluminium scanning arms, which must be positioned, in the above picture on the left (leaning on the black cover) and the right side (artificially placed for the photo!) of the rim-edge. The built-in computer thereby receives all the necessary data about the wheel to be balanced. Once the protective cover is brought down, the test run begins.

Both arms are, at the same time, designed for the taking on of weights. The display-screen shows the position of where the weights should be clamped- or stuck on. The scanning arm (with the weight) is now brought to the indicated point, the computer then gives the green light on-screen. The procedure is repeated on the other side with the second scanning arm. Of the many special functions, only one will be mentioned here. There are buyers of alloy wheels who don't want to spoil the outside appearance with unsightly balance weights. In this case, the machine determines the outside weights in such a manner that they can be stuck on the inside of the wheel-rim, below the rim-bowl, perhaps even in two parts under the wide aluminium spokes. 11/10

For balanced wheelsthe center of gravity is right in the middle.
