Tyre balancing machines for uniform driving
Tyre balancers combine numerous technical functions and are small all-rounders when it comes to the correct mass distribution of tyres. Different designs and other differences between the individual models allow specialisation in certain areas of application. This means that tyre balancers are generally suitable for any type of tyre: whether truck, car or motorcycle.
RP-TOOLS offers an extensive range of tire balancers in its product line. The range covers a wide spectrum of applications and is suitable for workshops, test centres, the private garage and more.
Unbalancing or balancing with balancing machines: How it works
Tyre balancing machines, also called balancing machines, are needed to find and correct so-called imbalances on a tyre. Imbalances occur in rotating bodies if the mass distribution on the rotating body is not balanced.
In concrete terms, this means that each tyre has an individual mass distribution, even if this distribution looks uniform in theory. There is a certain tolerance range in which an unequal distribution is carefree. However, if this is exceeded, the tyres start to wobble after some time of driving. This flapping is not only annoying, but can also lead to impairments of the vehicle:
For example, the steering gear is subject to heavy strain and can suffer damage if an imbalance is not corrected promptly. In addition, defects can occur in the tyres themselves and in the axles.
Preventing problems thanks to tyre balancers
The reason for the uneven mass distribution is the uneven wear. Unlike in theory, the individual tyres wear differently due to different conditions. For example, even the weight of the small valve can be enough to make imbalances necessary. Other factors are strong braking maneuvers and cornering.
The imbalance can be corrected with the help of small weights, which are attached to the appropriate places. The balancing machine determines exactly which points are involved.
Static and dynamic imbalances
There are two types of unbalance: static and dynamic unbalance. One speaks of static unbalance if the unbalance can also be verified in the static state, i.e. without rotating. This is the case, for example, when one side of the wheel is heavier than the other side. Here, when oscillating, it can be seen that the heavy side is always at the bottom at the end of the process.
Dynamic imbalance occurs, however, when the axis of rotation of a body does not coincide with its stable main axis. This case occurs when there is a different mass distribution on both sides of the wheel, i.e. on the opposite sides. Dynamic unbalance can only be determined when the wheel is rotated.
The task of the tyre balancing machine in detail
Unbalance can occur on the tyres of motor vehicles. Whenever tyres of a motor vehicle are remounted, they should be balanced beforehand. This is done with the help of a tyre balancing machine by determining both the static and dynamic imbalances on a tyre.
To do this, the balancing machine first records the centrifugal forces of the tyre during rotation and converts them into the so-called unbalance values. The tyre balancing machine requires three values, which must be entered at the beginning of the process:
- The rim width
- The rim diameter
- The distance between the inner rim flange and balancing machine
If unbalances are diagnosed by the balancing machine, they can be corrected by means of balancing weights. The balancing machine provides information on where the balancing weights are to be placed and how heavy they must be. In a short video we will introduce our model RP-U120P and its function in more detail. Feel free to stop by and see how the unbalance process looks like.
