Balancing Machine for Vehicle Tires
110 RBAV | 110 RBBV | 110 SBAV | 110 SBBV

Range of application
Measurement of the unbalance in passenger vehicle tires of various sizes in one or two planes. Classification of the measured unbalance and marking. Use of the machine in series production with a mixed operation for quality control or development. The machine can be linked with other plant equipment by suitable conveying system.

Design
Single-station machine with automatic operating sequence.

Vertical balancing unit with sub-critical suspension system, precision spindle, vibration sensor and angle encoder; drive by AC servo-motor.

Mounting of the tires in variable tire clamping chuck or a stepped adapter that can be inflated.

Measured data processing by microcomputer measuring unit CAB 850, classification, and if required, marking of the tire.

Loading and unloading of the machine manually by the operator or automatically by integrated transporter. 

Especially in the case of high-performance or wide tires the couple unbalance can result in undesirable vibrations. This is an important quality criteria and should be corrected in addition to the static unbalance. To do this it is necessary that the tire be checked in its correct shape and position. Stepped and split adapters that can be inflated are the correct solution for this application. To ensure a perfect seating, after the adapter is locked in position the lubricated tire is first of all inflated to over-pressure and then deflated to its service pressure.

For checking static unbalance within the framework of quality control it is not necessary to inflate the tire. The unbalance measurement is done in one plane only. A tire clamping chuck that is spring-activated and pneumatically unclamped is used for mounting the tire. This chuck covers a wide diameter and height range and does not have to be changed.
