Where are single chamber diaphragm brakes chambers generally used?
Trucks with air brake systems have them on the steer axles. Trucks with steerable pusher axles usually have those... non steerable pusher and tag axles (the difference between a pusher and a tag axle is that a pusher is located in front of the drive axles, and a tag axle is located behind) can go either way... they might have a single chamber 20 can or a dual chamber 30 can. Some trucks also only use dual chamber 30 cans on one drive axle, meaning only one axle has spring brakes... I see this often on the International Prostar, but have also encountered it on some Kenworth T2000s.
What is the purpose of a pusher axle on a dump truck?
It allows more weight to be carried. Bear in mind, it's only a pusher axle if it's located in front of the drive axle(s) - if it's behind, then it's a tag axle.
What is a quad-axle dump truck?
A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.

What does a quad-axle dump truck look like?
It looks like a dump truck that has another axle in front of the tandems at the rear of the vehicle. Most people who have these trucks have a mechanism to allow the fourth axle to be raised when it's not needed.
What is a tri-axle truck?
A truck with three rear axles and one of the axles is a drop axle that is only used when carrying heavy loads.
What is the purpose of a tag axle?
Tag (also referred to as lift) axles allow more weight to be carried, by creating more of a contact surface with the road for weight to be distributed on. When it's behind the drive axle(s), it's a tag axle; when it's in front of the drive axles, it's a pusher axle. Some companies set up tandem axle trucks where the rear drive axle is a tag axle, so that it can be lifted up to shorten the turn radius of the tractor. Schneider National used to have some Freightliner Argosy COEs which were set up this way. In Europe, the use of a tag axle doesn't increase the amount of weight which can be totaled, but their use is encouraged because it puts less stress on the roadways than a 4x2 tractor. Tag axles can be somewhat problematic - especially on a single axle truck - in that they effectively can turn the drive axle into a fulcrum, placing extra weight on the steer axle. However, in many states, total allowable gross weight is determined by vehicle wheelbase, and tag axles may be used rather than pusher axles because they effectively extend the vehicle's wheelbase, thus allowing a higher gross weight.
What is the axle ratio in a 2005 Jeep Wrangler?
The ratio is on a tag on front and rear axle between 2 of the cover bolts
Is there a semi truck with two axle's but has only one drive axle?
You mean with tandem axles, or with just two axles total? In the case of having two axles at the rear, yes. This is pretty common in Europe, where a standard 2x4 tractor will have an additional tag or pusher axle in order to reduce wear on roadways. In the US, it isn't so common, but it's not unheard of. I know Schneider National used to run some Freightliner Argosy COEs which had a single drive axle and a tag axle behind it.. when backing, the driver could raise the tag axle, and it would shorten the overall wheelbase of the power unit, allowing for tighter turns to be made.

What axle is the drive axle on a triaxle?
A tri-axle has two live axles and a lift axle.. if it's located in front of the drive axles, it's known as a pusher... if it's located behind the drive axles, it's known as a tag axle. With a tandem axle setup (which is what tri-axles, quad axles, etc. are, albeit with the addition of dead axles), the driveshaft runs from the transmission output to the power divider. The power divider is a differential which transmits power evenly to both live axles.
Why do some lorries have three axles?
Weight distribution. In the UK and EU, the 4x2 configuration is the "norm", and there can be up to 40,000 lbs. on the drive axle. This is very strenuous on the asphalt, and some trucks have an additional lifting tag or pusher axle to better distribute the weight, thus reducing the strain placed on the roadway. Vehicles intended for heavy haulage have a non lifting axle, and are in a straightforward 6x4 configuration. Again, this is for weight distribution.
