Automotive Technology: A Systems Approach Chapter 39
thrust loading
acts on the axle bearing parallel with the center of axis
radial loading
always present whether or not the vehicle is moving
Rzeppa joint
fixed ball-type joint
croos groove joint
has a flatter design that any other plunge joint
semifloating axles
help to support the weight of the vehicle
slip yoke
internally splined and its outside diameter is precisely machined to fit into the rear seal
fixed joint
it does not plunge in and out to compensate for changes in length
inboard joint
joint nearer the transaxle
outboard joint
joint nearer the wheel
hypoid gear
makes contact with a sliding motion
limited-slip differential (LSD)
manufactured under such names as sure-grip, no-spin, positraction, or equal-lock
three-quarter floating axle
on the outside of the axle housing instead of inside the housing as in the semi floating axle
plunge joint
one that is capable of in-and-out movement
ring gear
rotates and turns the differential case and axle shafts
preload
set by tightening the pinion nut until the desired number of inch-pounds is required to turn the shaft
full-floating axle shaft
slid over the outside of the axle housing and carry all of the stresses caused by torque loading and turning
torsional damper
small damper weight
dead axle
supports the vehicle load and provides a mounting place for the wheels
hunting gear sear
the drive pinion hunts out each ring gear tooth
partial nonhunting gear sets
the number of ring gear teeth that are contacted
live axle
transfer torque from the differential to each driving wheel
double-Cardan
used with splint drive shafts and consists of two Cardan U-joints closely connected by a centering ball socket and a center yoke, which functions as a ball and socket
double-offset
uses a cylindrical outer housing with straight grooves and is typically used in applications that require higher operating angles and greater plunge depth
nonhunting gear set
when one drive pinion gear tooth contacts only certain ring gear teeth
