Inflation Machine for Vehicle Wheels
110 SBFR | 130 SBFR

Range of application
Inflation of tubeless passenger vehicle tires in normal, low profile and super low profile design. Suitable for tires mounted onto steel or light alloy rims of various dimensions.

Application of the machine in series production.

Simple integration into existing or new lines, with a preceding tire-mounting machine, and succeeding tire-bead stabilization machine and wheel balancing machine.

Design
Single-station machine with fully automatic sequence, loading and unloading of the machine by a fully automatic conveyor system.

Double belt conveyor on welded stand with lifting function, inflation table with flat seals, centering device, inflation bell and hydro-pneumatic lowering and locking equipment installed.

Sequence of operations

• Automatic transfer of the assembled wheel from the feeder belt into the inflation station by the double-belt conveyor
• Automatic sequence: Lower the transporter and lay the wheel onto the inflation table
  Center the rim and tire, lift the wheel and set onto the table.
  Lower the inflation bell onto the tire and inflate to the required pressure
  Lift the inflation bell
• Automatic transfer of the inflated wheel in the direction of the balancing machine

The special construction of the patented inflation bell does away with the normal rim-sealing arrangement and is therefore practically wear-free. In addition light-alloy rims with edgeless spoke design can be inflated without problems in mixed operation, and machine operation is independent of the rim design. Due to the absence of the counter-force exerted by the rim sealing ring used in conventional systems, no loads are acting on the rim. This is an important aspect in the case of thin-walled rims with high sensitivity to side pressure.

By control of the inflation bell a high inflation accuracy and good seating of the upper tire bead is achieved. The lowering depth of the bell is automatically adapted depending on the individual properties of the wheel combination through a specific, empirically-determined inflation program. The inflation pressure program is selectable manually or automatically through the program control.
