"This bus should not be on the road"
-
Lets see, the suspension and the vehicle tilting to one side...
Road conditions, if not favorable, would make the bus tilt to one side also. Next is the air reservoir, if not enough air, the bus will also tilt to one side. Take a SMRT Habit for example (like this, I use TIB1224Y again), after a night of parking, it will tend to tilt towards the back. The engine weight would tend to pressurize the rear axle, making the axle 'sink' down, and the air escapes from the compressed cylinders supporting the axle and that particular section of the bus. The problem was 'solved' once, but it came again, when the rear section 'sinks' even when the bus is in operation, warranting a repair and the bus captain had to go off service to change to another bus.
Another case affects the entire bus, when all of the axles lost the air and practically the bus becomes 'low floor' (means it no longer tilts to only one side, both sides go down together). Spotted with such a situation was a WA bodied Merc of SBST, the entire bus sunk onto its suspension supports and when it goes over a bump, yes, the passengers bump together.
Maintenance, yes, daily operations still brings trouble. Why hook operational headaches with fare rise and etc? -
It's very obvious that Singaporeans are trying to find fault with EVERY single little thing they can find, and try so futilely to link with fare rise. If I was standing beside them I would definitely give them a slap. Surely suspension problems and worn out tyres are problems, but they are naturally-occuring problems. It doesn't make any sense to link them with fare increase.Originally posted by TIB1224Y:Lets see, the suspension and the vehicle tilting to one side...

like i said in trains forum it is human nature to blame others when something goes wrong and u get angry. frankly speaking from the view of a public the bus tilt to one side just doesnt look normal so it seems unsafe, though im not saying its SBST faultOriginally posted by Oceane:It's very obvious that Singaporeans are trying to find fault with EVERY single little thing they can find, and try so futilely to link with fare rise.

Bellow plate corroded. Used to have a lot of such problems with MB0405 because of vehicle age. The MB0405 bellow plate is welded onto the chassis. So need to send vehicle for chassis refurbishment. Corrosion treatment. Then refit a new bellow and shock absorber.Originally posted by xunmengzitu:STOMPer Steven Lim found two things disturbing yet interesting about this bus.
He took these photos at about 9.15am on 18 Oct and sent them in an email to STOMP today (1 Nov).
"You can see the bus is tilted to the right dangerously. Is it safe? Is the suspension spoilt and not replaced?
"You can observe that the tyre of the bus has worn off. Why is it still being used? SBS saving costs?" he asked.
"With the current increase in fares, how could SBS be overlooking such issues. Safety can be compromised with higher fares?" the STOMPer asked.
Steven said he wrote to SBS Transit.
"I appreciate that SBS has taken a serious view on this matter and replied on my concerns. I understand that a strict maintenance regime is in place for all buses," he said.
"However, I still strongly feel that when this clearly visual obvious situation has arisen, the bus driver on duty should be given the rights and authority not to drive the vehicle as it poses a hazard to commuters and other road users."
The bus chassis will tilt to the opposing side during cornering, with the cabin further tilted, it can cause accident due to the extreme shift in CG. -
What is a bellow ? Is it fitted on top of the airbags as well as below it?Originally posted by MS:Bellow plate corroded. Used to have a lot of such problems with MB0405 because of vehicle age.

i only know of bellows on accordionsOriginally posted by Scania N113CRB luver:What is a bellow ? Is it fitted on top of the airbags as well as below it?

Someone should just tell Steven Lim to STFU

Air bags are the bags charged with gas during collision to inflate and cushion impacts.
Air bellow is a very thick rubber container with 2 hollow ends used to contain pressurized air when inflated during engine operation. The air bellow fits to the bellow plate like a tyre to rim; air tight.
Air bellow is also known as air springs. It replaces the function of a coil spring of a normal car suspensions. -
I see . The Air Bellows are reinforced with steel wirings right? Otherwise the rubber compound must have been extremely strong to withstand such high pressure .Originally posted by MS:Hold it...

Anyway thx for your info .
