Abstract
The invention relates to a bevel gear box for use as part of the steering mechanism of a commercial vehicle. The invention may be suited to use where the controlled axles of the vehicle are located below the passenger compartment. The bevel gear box may comprise box housing, which in turn houses two separate bevel gear barrel assemblies. The exemplified bevel gear barrel assemblies each comprise a bevel gear, the bevel gear further comprising a gear head incorporating teeth and a gear shaft. Shaft housing surrounds a circumference of gear shaft. To enable the bevel gear to rotate within the shaft housing, bearings may be placed between surfaces of the bevel gear and the shaft housing. The face of the gear head may comprise a gear head recess for location of a center dowel therein.
