parallelogram/worm type gearbox components
Includes a pitman arm, a center link, and idlers arm and two tie-rod
assemblies, may also include a steering damper.
rack-and-pinion gear operation
when the steering shaft turns the pinion shaft, the pinion gear acts on
the rack gear. The rack then slides sideways inside the gear housing
parallelogram/worm type pitman arm
transfers gearbox motion to the steering linkage. It is splined to the
gearbox sector shaft.
parallelogram/worm type ball sockets
provide for motion in all direction between two connected parts.
needed so the linkage is not bent and damaged.
Parallelogram/worm type center link
also called a relay rod, simply a steel bar that connects the right and
left sides of the steering linkage. has holes to accept the pitman arm,
tie-rods and idler arm.
,Parallelogram/worm type Idler arm
supports the ends of the center link on the passenger side of the
vehicle. It bolts to the vehicles frame
parallelogram/worm type steering damper
oil-filled shock absorber found in some parallelogram linkage.
Attached between the vehicle's frame and the center link to help
absorb road shock before they reach the steering gear
parallelogram/worm type tie-rod assembly
fastens the center link to the steering knuckle. Consists of two tie-rods
and a toe adjustment sleeve. tie-rod that connects to the center link is
the inner tie-rod, the tie-rod that fastens to the steering knuckle is
called the outer tie-rod
Toe adjustment sleeve
provided for changing the length of the tie-rod assembly during
wheel alignment
, Recirculating-ball gearboxes
used with a linkage steering system on large trucks. Has small steel
balls that circulate between the gear members.
recirculating-ball gear box components
worm shaft, a sector shaft, a ball nut, ball guides, the gear box
housing, end cover
recirculating-ball gear worm shaft
it is the input gear connect to the steering column shaft. The balls fit
and ride in the grooves in the worm gear.
recirculating-ball gear sector shaft
is the output gear from the steering gearbox. It transfers motion to
the steering linkage. A sector gear is machined to the inner end of
sector shaft
recirculating-ball gear ball nut
rides on the ball bearings and the worm gear. Grooves are cut in the
ball nut to match the shape of the worm gear. It slides up and down
and the worm gear rotates
recirculating-ball gearbox housing
provides an enclosure for the other components. Seals and prevents
lubricant leakage.
