What is attached to this bus wheel? - Tyre Pressure Monitor!

hrishig · 8th April 2009, 17:06

Just saw a bus in pune having this attachment for all wheels ( Front + Back) Couldn't make out if this is just for visual(!) pleasure or some useful attachment.

Any idea?

cable for speedometer/odometer?

Looks like it is connected to the tyre's air valve. Some sort of tyre pressure regulator thingy? Which bus is this?

Is there a tube attached to the tyre valve?

Maybe it is some sort of Tyre Pressure monitoring system?

Do you have the picture of the rear wheel attachment?

rranjith_kum · 8th April 2009, 17:27

Well I guess its some ingeniously self made tyre pressure monitoring system.
I wonder how the connection was in the rear,

I m inquisitive about the chrome thing, is it some kind of a pump ??

Continuous Tyre Pressure Monitor. If connected to a source of compressed air, you can also dynamically alter air pressure on the move. The piece in the centre is the rotating joint, which is connected to the valve through another airhose that you can see in the pic.

I don't think the chrome thingy is a pump. It will be some sort of a cover for a rotary housing which will hold the tubes stationary on a rotating wheel.

For the pump they might be using the air brake pump itself as that is pretty heavy duty. Also buses already have a tank for storing compressed air.

The above is only a guess as I am not sure what that thing is in the first place.

The bus is having it for rear wheels also. Spotted this bus a month ago at Swargate. I was not carrying a camera at the time.

Yes, it is connected to the tire's air valve. It is a Self Infalting Tire System, It monitors the tire's pressure continuously and inflates tires as necessary. As far as I know it uses the air from the air brake to inflate the tires.

Also see this post - a fellow bhpian took pics of a similar setup on buses in Buenos Aires, Argentina.

I guess the next question is who is running this and why? I've seen military 4x4s use it get across sandy stretches etc.

Maybe next time ask the driver whats going on.

condor · 8th April 2009, 19:40

Defence bus ?

Have seen similar pics of self-inflate-on-the-move equipment.

True, they deflate on sandy stretches and infalte back when they are on road.

In this case I guess, He is just keeping the tire inflated at the right pressure at all times for better tire life and also to avoid uneven wear and tear which is very common on our indian buses. Trying to economical on the tyre front I guess.
