The invention relates to a vain device for dialing modes Balancing of motor vehicle wheels directly or afterwards on the highest vehicle Suspension of the R&D on an axle that can swing in a stand with a movable front * direction for driving the vehicle wheel, one at SchwingAingSffleßeinrichtung attachable to the wheel carrieri together with a device for determining the phase position.

There are balancing devices known that a balancing of motor vehicle wheels directly on enable tall vehicle. One spares So with these balancing devices, the removal of the wheel of the motor vehicle, the placement of the same on a balancing machine and the subsequent Reassembly of the wheel on the vehicle. Have such balancing devices the advantage that also imbalance components, which on the brake drum or on a not exactly centric Clamping of the wheel are to be traced back, in which the balancing process is recorded. Particularly These balancing devices have proven to be advantageous, for example, in trucks or in Omnibuses, since the wheels of the same are heavy and the assembly and transfer of the wheel to one Balancing machine requires considerably more work than, for example, with passenger vehicles. The disadvantage of these balancing devices, however, is that with them only a part of the Balancing tasks can be mastered. For example, motor vehicles with differential gears the rear wheels connected to the differential gear do not match the ones in question Balancing devices are balanced, because the unilateral drive of a wheel Differential would be damaged. Furthermore, especially if the steering is knocked out a bit is, the determination of the unbalance of the front wheels cause difficulties And a dynamic one Make balancing the same impossible. For this reason, the workshops also need the The balancing device in question is in any case still a complete balancing machine.

Based on this problem and the aforementioned prior art, it is therefore an object of the invention, the known balancing devices for balancing motor vehicle wheels to add a cheap auxiliary device to high-jacked vehicles to complete scrubbing machines, in order to be able to balance even if this is not possible on the vehicle.

This object is achieved by a device balancing device

for optional balancing of motor vehicle wheels directly on the raised vehicle or after hanging the wheel on a swingable in a stand mounted axle with a mobile device for driving the vehicle wheel, a Vibration measuring device attachable to the wheel carrier together with a device for determining the phase position, which according to the invention comprises the following parts: a stator, one mounted therein so as to be oscillatable Axle for clamping the wheel in such a position that it is connected to the mobile drive device can be brought into engagement, as well as an approach on the swing bearing for attaching the vibration measuring device.

The drawing serves to explain the subject matter of the invention. It shows
