buggys and 3diffs. ???

[ToRqUe]

Y do buggys have 3 diffs. ???

 

[vbgagnon]

They have 3 diffs, because the its the only way to distribute the power.

 

[AC48]

Well, it's not the only way. All, I think, 1/10 R/Cs only have two diffs. The center diff makes it so the power can be split between the front and rear diffs. With three diffs, only one wheels must be spinning at all times (except for idle, duh). Some people lock the center diff so that 2 wheels have to spin, correct me if I'm wrong but I think this makes for better extreme off roading. Buggies are mainly for track use and the center diff helps it out on the track.

 

[ToRqUe]

so what does the center diff. really do ??? and y does 1 wheel have 2 slip ???

 

[vbgagnon]

check this out, its a thread from a about a month ago. It explains how diffs work.

Diffs

hope this answers your questions.

 

[ToRqUe]

i kno how diffs. work but i dont knop y buggys need there and y 1/10 scale only use 2

 

[cvec7]

Vehicles like Stadium trucks use one diff/tranny.

 

[ToRqUe]

y that is the only part. y do they alll use different amounts of Diffs. ???

 

[vbgagnon]

a 4wd vehicle is very different then a 2wd vehicle. the center diff is kind of like the tranny in a monster truck it distributes the power evenly to the front and the rear, then the front/rear diffs send the power to the wheels.

 

[ToRqUe]

so on my t-maxx the tranny is a diff. on the buggy ???

 

[vbgagnon]

yes the diff on your tmaxx is your tranny, they are not exactly the same (obvoulsy) but comparable

 

[ToRqUe]

ight , iw as finna have a heart attack tryin' 2 figure this out and what did cvec7 mean when he said that stadium trucks only had 1 diff. ???

 

[vbgagnon]

after the clutch bell there is the tranny the output to the dogbones.

only 1 diff

 

[cvec7]

ight , iw as finna have a heart attack tryin' 2 figure this out and what did cvec7 mean when he said that stadium trucks only had 1 diff. ???

Stadium trucks have a whole tranny/diff unit as one. The after the spur, the power goes straight to the wheels via 3 internal gears. 2 actual gears, and the 3rd and final one is the actual differential which is much smaller than a buggy diff.

 

[vbgagnon]

that makes a little more sense then my explination, but I've never taken apart a st truck tranny.

i feel as though since 1/8 buggys are used mainly for compitetion, the fact it has 3 diffs allows for more custom tuning using different weight oils for the drivers style and to the tracks surface, and the ability to tune front and rear brake bais independently. (brake bais meaning more braking power for the front or rear wheels). having no center diff would make the car have more extreme off-road traction..but would also make it less stable during cornering and accelration on smoothed out tracks. the center diff would also help out softening the blow from constant on-gas landings to the drivetrain.

 

[ToRqUe]

u can tune diff. w/ different weight oil ??? thats crazy i wouldnt sit there an do all that 4 a race unless it has a big difference

 

[cvec7]

Yes, it does make a pretty big difference. Most people will definatly agree.

1/8 have a centre diff to allow for speed variations between the front and rear wheels. On a 1/10 cos they dont weigh much any variations is just relieved by a wheel spining. On 1/8 cos they are pretty heavy without a centre diff the transmission would wind up and cause a lot of strain on the uj's, bevel gears, planetry gears dog joints e.c.t, e.c.t and make them wear out rather quickly. I've got a suzuki sj and i used it on the road once with it still in 4wd mode and sheared the front prop off cos of tranny wind up. Like matey said you only have to have one wheel off the ground to lose all power to the other wheels. Then you're into the world of LSD's (Limited Slip Diff).

 

[ToRqUe]

but on the 1/8 buggys y would u have a vareation in speed what the big deal
