How does the wheel mount for a lowered-floor bus work?

I’ve always wondered what sort of structure transfers a lowered-floor bus’s weight to the (front) wheels?

There’s a lot of weight riding on those wheels, and not much space in that wheel well for bracing or anything to keep the wheel from splaying out.

And unfortunately, a web search turns up nothing but bus dealers, repair shops, bus accessories, and news reports of transit agencies switching to this style of bus.

Google Images for low floor bus front axle produces several diagrams that may be helpful.

Thanks for the tip. Those images do explain quite a bit, but it looks like most of them attach at the top, which leads back to the question of how support is transferred to the frame which has to sit 2-3 feet below the the center-point of the wheel.

Also, try a search for kneeling bus. It allows passengers in wheelchairs to board easily.

And it’s the back axle that carries the weight. That’s where the engine is.

The front axle is shaped like a U. The suspension is a series of air bladders. The bus “kneels” by venting the air out.
