Why do so many Americans hate European trucks?

I love how unless we conform to your ideals, we're wrong. I think it looks cool and so do many others.

 

Sorry 18 speed Eaton .....has got you beat too.....

RT-18

• “Unbeatable versatility with 19.7 to 1 overall reduction and 14.40 low gear.
• Economical performance with 0.73 and 0.86 overdrives for efficient cruise RPMs”

 

Not really. The Traxons are build for the European market, so a maximum speed of about 55 mph. You don't need 18 speeds in that situation.

I'm still waiting for the complete graph of the engines, that will show exactly what I wrote.

 

Eaton 18 has a Lower overall 1st gear too....... but you ignore that.....

 

No, it hasn't. The Eaton has a 1st gear ratio of 14.40, the Traxon 14.68, so a bit lower. By the way, that is the 16 speed overdrive version of the Traxon.

 

So you got me on that one...

 

Compounds means two turbos, which acerts use.

 

Both Cummins and DAF graphs of torque and power curves are inaccurate at low rpm's, Cummins below 1100, DAF below 1000 rpm.
In both cases they have contradictory data.
Example:
DAF shows more power for the MX-13 355 than MX-13 390 @ 800 rpm, or just above 800, yet the torque curve shows a higher torque (at this engine speed) for the 390 than for the 355. As you know, this is mathemaically impossible.
Torque at low rpm (800) for the 315 is clearly lower than 390, yet power shows same level.
As you know, this is mathematically impossible.


The Cummins curves are not accurate at low rpm's either.
At the point where the horizontal axis crosses the vertical, there is no value on the horizontal axis.
Then at next intersection it says 1000 rpm, next 1150 (150 rpm interval) then 1200 (50 rpm interval), and 1300, 1400 etc (100 rpm intervals)
Also the Cummins power curve shows 425 hp at 1000 rpm, which can not be true. This corresponds to torque of about 2230 lb-ft. So higher than the maximum of 2050.

The curves I posted are based on the data that seemed to be accurate.
I can make up data and put them in a chart, but what is the point?

 

True.

But this is not a completely fair comparison, without taking drive axle ratio in consideration.
The Eaton has a 0.73 overdrive, versus 0.82 in the Traxon.
If you want an overall ratio of 2.45 in highest gear, that would mean 3.36 axle ratio for the Eaton, 2.99 for Traxon, assuming these ratios are available, which may not be the case for the 2.99.
Eaton: 0.73 x 3.36 = 2.45, Traxon 0.82 x 2.99 = 2.45.

In low gear the Eaton (14.4) with 3.36 would have an overall ratio of 48.4.
The Traxon (14.68) with 2.99 has an overall ratio 43.9

The overall ratio spread for the Eaton 18 is 19.73 (14.4/0.73) vs 17.9 (14.68/0.82) for Traxon.

 

^^^^^^^^

Where have you been ....

And the Mx is really a 1800 foot lbs engine multi torque or not......
