[Gearboxes] ZF vs Voith
-
Recently I had observed that both gearboxes have their pros and cons. As well as the percentage of stress on the engine. Which one is better in speed , fuel efficiency , prone to overheating [of engine] and last but not least , vibration and jerkyness. Please share ur view below if u are interested. Also , state the bad points of these 2 gearboxes. =)
**Those of u here who are trolls here , listen. This thread simply follows the forum theme : Buses.**

A good comparison between these 2 gearboxes would be the MB O.405G [SMRT] .
-
Try TIB1161U. Quiet engine and powerful acceleration on slopes.

Accleration wise, they are no better than Allison. I'm for Allison Transmissions.

ZF Gearboxes have very high torque and gives jerks to gear changes but sometimes also tends to lock up. It's mainly good for the fast acceleration buses.
Voith Gearboxes have a smoother acceleration and high RPM but it's generally has a slower acceleration than the ZF gearboxes.

SBS7421Z is actually voith but it sounds abit ZF

Most B9TLs regardless of gearboxes have very fast gear change, much like the VO2X.

oo i see.. how about this lol? SBS594D

I donno things about gearboxes, somebody guide me?

ZF picks up much btr than Voith partially cos it also has a lock-up either before or after 2nd gear.

That's the wrong reason.Because Voith locks up during the transition from first to second. So why should ZF pick up better because it locks up either in first or second when Voith does it between first and second.
And engine torque and gearbox setting is more crucial than the gearbox make. The ZF MKIII is just as slow as the Voith ones. The ZF B9TLs are just as fast in pick-up as the Voith ones.

I prefer Voith over ZF.
I find it quieter and more reliable.
-
I like the Voith's retarder..... But I also like the ZF due to it's whine when the engine is idle. But , a B9TL with a Voith pwns it all! Yeah baby!
-
I like ZF more than Voith,but this does not mean Voith sucks,I still like it

Maybe ur right too...... Compare O.405G with the ZF and Voith...... But it seems Voith always win in terms of engine speed..... Correct me if I'm wrong?

Compare a Voith Volgren O405G and a ZF Volgren O405G,compare which is faster
P.S : I personally think that ZF Volgren O405Gs are faster.

Well , different people different thinking.

Share with us why u like ZF more then Voith? Thanks

Well,I like quite powerful buses,ZF makes the bus sounds more powerful (Compare ZF Volgren/Habit bendies with Voith Volgren/Habit bendies).ZF bendies sounds very powerful while Voith bendies sound like no power (unless over revving)

Chey..... So it's just the matter of sound for u? I see.

Volgren Voith : http://www.youtube.com/watch?v=h1IPygP9gSEThe ZF on MB O405G sounds the best..... Voith is only capcable of giving the engine stress ;)

But then ZF give too much power,look what happened to TIB1105H,TIB1110S,Voith no known case of burning buses excpet for TIB1234T (I think),the fan belt burned

Yah. Boarded 'my' bus that time and kenna fanbelt burnt incident on my favourite svc 960 somemore.Should be the best gift ever....lol
