STEERING SYSTEM
The re-circulating ball typeis a past favorite #ecause the #allsact as a rolling thread #et!een the !orm gear and the #all nut. Itis used in most commercial vehicle/s steering system. 'ith thissteering gear turning forces are transmitted through #all#earings from a !orm gear on the steering shaft to a sector gear
on the cross shaft.
#all nut assem#ly is 5lled !ith #all #earings !hich 6roll7 alongtu#es #et!een the !orm teeth and grooves inside the #all nut.
'hen the steering !heel is turned the !orm gear on the end of the
steering shaft rotates and movement of the re8circulating #allscauses the #all nut to move up8and8do!n along the !orm.,ovement of the #all nut is carried to the sector gear #y teeth onthe side of the #all nut. The sector gear in turn moves !ith the#all nut to rotate the cross shaft and activate the steering lin0age.
The #alls re8circulate from one end of the #all nut to the otherthrough #all return guides.
