Universal joint

[Bushwacker]

What would the use of this type of joint in the front propshaft of the KZ be
Why not a normal universal joint?

[hentey]

Pieta,its to handle all the torque.......

[Bushwacker]

If that's the case, why not one at both ends, and on each end of the rear propshaft :wth:

Piet, it's called a double cardan joint ... almost like two universals together. When there is a sharper angle, a universal will perhaps still rotate through that angle but with a jerky motion. The double cardan however is smooth through greater angles. (It has nothing to do with being able to handle extra torque ... sorry Hentey )

The front propshaft is shorter. Greater angle to work on.

No problem Andy,I was merely yanking Pieta's chain.However I must be honest,I didn't know what it was for.

Siende dat die voorste dif op n KZ nie beweeg nie sou mens egter gedink het dit sou beter agter gewerk het.

As Gert said, the front prop is shorter and the angles are therefore maybe a little more tight, even if the diff is fixed. Obviously on the SFA the angle varies with articulation and the diff pinion is already angled slightly upwards, that's why there is no double cardan on the diff end of the prop. The rear prop is much longer and although it articulates only after the carrier bearing, the articulated section is still considerably longer than the front prop. In addition, the non articulated section of the prop already takes up a little of the downward angle and hence there is no need for a double cardan on the rear prop. A point of consideration is stresses on the bearings of the x-fer case out-put shafts .... this is what the carrier bearings are there for .... to relieve undue stresses. On the KZ's fixed diff there is no need for a carrier bearing in the front shaft, but the SFA does have one right up close to the x-fer case and that is where the double cardan joint is located ... for a smoother rotation with less strain on the carrier and out-put shaft. It's all done that way for good reason.

No but seriasly why

Nissan, Ford, Isuzu, Datsun etc etc etc sou net 'n universal daar gebruik het want hy sou die job kon doen maar oor tyd kan die stresses dalk net te veel raak. Toyota dink vooruit en bou goed wat hou en daarom eerder die double cardan joint in gesit want hy sal langer hou

To save the bearing and shaft seal on the front out-put of the x-fer case .... without it you'd have to be replacing them from time to time.
