Internal Main Wheel Assemblies

产品概况：

The internal main wheel assembly provides partial support of the weight of the aircraft and a means of steering control. When mated with the brake assembly, the wheel assembly provides the braking operation by driving the rotating-disc members of the brake assembly.

Internal wheels are made from magnesium or aluminum forgings. The wheel is of the divided type, incorporating inner-wheel half and outer-wheel half, which are fastened together with tie bolts, washers, and nuts. The wheel rotates on two tapered roller bearings which seat in bearing cups, shrink fitted into the hubs. The wheel will have an inflation valve to inflate and deflate a tubeless tire, along with a rupture-disc assembly to release tire pressure, if the tire is over pressurized.

The inboard half of the wheel has drive lugs that engage the drive slots of the rotating brake discs The drive lugs are lined with steel drive keys, which are held in place by screws. Stainless steel heat shields are located between the drive keys.

APPLICATIONS:
General and business aviation, turboprop passenger, and helicopter.
