tintinspartan SG 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?
Scania N113CRB luver SG the shrieking of the tires . That time i took one on 72 and i could feel the tires' vibration .
The_Bus_Guide SG 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.
^tamago^ SG actually 9812R also leh, if u sit lower floor side-facing seats, can feel the tyres screeching.
shinkansen83 SG 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.
Raraken SG Err, isn’t the articulator supposed to do that? BTW, we’re talking about tag axles, not Articulators.
Scania SG 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.
stooper SG Because the buses are not in sharp turns at low speeds! See the front axle of the LO3x only turn a bit.
tintinspartan SG Try to go to Boon Lay Bus Interchange and stand at the 90 degrre turn near Ticket Office. Then you see for yourself.
The_Bus_Guide SG 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. http://suhirman.fotopic.net/p32627344.html
