Airbagged Trailer Axles

The air valve sensor control on the ASI axle was designed with Transwest Truck Trailer RV of Colorado. The air valve sensor control keeps the trailer level regardless of load . This is the purpose of aftermarket air bags we put on pickup trucks.  Andrew Lyons of Transwest explains, “dropping the trailer lower to the ground for loading and equalizing the weight on each axle is a big benefit for hauling horses.” With ASI axles you can lower the trailer almost 3 inches. The axles come with air compressor, air tank and an air heater and dryer just like the big 18-wheelers. Cimarron Trailers helped develop and test the new hybrid axles. The air sensor also equalizes the axles so they carry the same weight over bumps and railroad tracks. You’ve seen the bridge axles on semi trailers with air bags that are far apart (9 ft), they have a similar air valve sensor to transfer weight back and forth between axles. That’s always been a drawback of torsion axles is they are independent of each other. Now with this hybrid air/torsion axle with the air valve sensor, the axles are tied to each other like leaf springs.

Picture above shows the attachment point of the axle to the trailer frame. the air bags to the rear attaches to Dexter torsion axles. This is the ride that could let your horses fall asleep cruising down the highway! The equalizing valve keeps the trailer level and the same weight on each wheel, no matter if you are parked on a curb, in a pot hole or those nice level fairground parking lots. How would you like to lower your trailer 3 inches to unload the horses or walk into the “Living Quarters.” The air tank with heater and dryer for automatic maintenance is in the bulkhead compartment with the air compressor. Picture to the right is the arm that attaches the axle to trailer frame.

Picture above is with the axle air bags totally inflated. Picture to left is with air bags deflated. Drop by Transwest’s booth in the Hall of Education at the National Western and walk in the horse trailer with the torsion-air axle and feel how soft it is.
