Volvo Olympian 2nd and 3rd Batch: Have 2nd Axle steering!
-
I dun believe it when a Volvo Olympian 2nd Batch turned into a corner and it's second axle was steering slightly, following the 1st steering axle (front axle). If the bus turns 60 degrees, the second axle will turn at around 10-25 degrees. Any bus specification expert could clarify?

LO 3 axles and VO 3 axles have that ability. VSOs and B9TLs do not have this feature.Originally posted by tintinspartan: I dun believe it when a Volvo Olympian 2nd Batch turned into a corner and it's second axle was steering slightly, following the 1st steering axle (front axle).

u shld hear the sound of Svc 21 B9TL's turning into the tight Kitchener Road.

the shrieking of the tires .Originally posted by ^tamago^:u shld hear the sound of Svc 21 B9TL's turning into the tight Kitchener Road.
That time i took one on 72 and i could feel the tires' vibration . -
To put it more specifically it is called a steered tag axle. Contrary to what I have believed previously, the wheels do not turn with the steering wheel. It merely 'follows' the direction of travel. This helps to reduce tyre wear as there is less force acting on the tyres while the bus turns. The noise and vibration from the B9/B10TL as compared to the LO/VO shows how difference it makes. However, I do not know to what extent the steered axle can turn.

actually 9812R also leh, if u sit lower floor side-facing seats, can feel the tyres screeching.Originally posted by Scania N113CRB luver:the shrieking of the tires .

Last time SBST use to have the bendy bus. When the bus turn into a tight
corner the section between the two cabin auto steer by itself. -
Err, isn't the articulator supposed to do that? BTW, we're talking about tag axles, not Articulators.

Yes, but also note that for 998Y, the rear non-powered axle is seerable, but in the opposite direction of the front axle, this helps the bus turns easier.Originally posted by Raraken:Err, isn't the articulator supposed to do that? BTW, we're talking about tag axles, not Articulators. -
Not very clear signs of steerable axle in both pics. -
Because the buses are not in sharp turns at low speeds!Originally posted by SBS3625D:http://i75.photobucket.com/albums/i298/SBS3625D/9035S.jpg

See the front axle of the LO3x only turn a bit. -
Try to go to Boon Lay Bus Interchange and stand at the 90 degrre turn near Ticket Office. Then you see for yourself.

Speed will not affect the angle of the steered axle; just the turning diameter. If the turn is sharp, even at low speeds, you can see the effect of the steered axle.
Below is a good example (even if its not a SBS bus). The bus is making a U-turn out of of the terminal.

Wow .. That bus ... its windows seems to be the largest i've ever saw !Originally posted by The_Bus_Guide:Speed will not affect the angle of the steered axle; just the turning diameter. If the turn is sharp, even at low speeds, you can see the effect of the steered axle.
