Information About The shaft collar and Universal Joint |
|
On front engined rear-wheel-drive cars, the rotary motion of the transmission's shaft collar is carried through the drive shaft to the differential, which causes the rear drive wheels to turn.
The drive shaft is normally made from seamless steel or aluminum tubing with Universaljoint yokes welded to both ends of the shaft (Figure 6-2). To save weight, some manufacturers useepoxy-and-carbon fiber shafts. Some drive lines have two drive shafts and three Universal jointsand use a center support bearing that serves as the connecting link between the two halves(Figure 6-3).
Four-wheel-drive vehicles use two drive shafts, one to drive the front wheels and the otherto drive the rear wheels (Figure 6-4). FWD cars, 4WD vehicles equipped with an independentfront suspension, and RWD vehicles equipped with independent rear suspension use an additional.
The shaft is anassembly of one ortwo Universal jointsconnected to a shaftor tube used to transmit from the power transmission to the differential. It isalso called thepropeller shaft.
Although most latemodel cars are front wheel drive, which are not equippedwith a drive shaftand Universal joint,the best sellingvehicles in Americaare pickup trucks,which do have adrive shaft and Universal joints.
These, plus the manyolder cars on theroad, give manyopportunities totechnicians trained inthe diagnosis andrepair of drive shaftsand Universal joint.
The short shafts or axles used onFWD, 4WD, andRWD with IRS arecalled half-shafts.
