Abstract
An air spring suspension system for vehicle axles reduces the dynamic force on the system's air springs during braking and acceleration of the vehicle and thereby prevents the diving of the vehicle chassis toward the road surface on application of the vehicle's brakes or acceleration of the vehicle.
Claims20
A suspension system for a vehicle having a longitudinally extending chassis and at least one laterally extending axle with at least one wheel mounted thereon, the suspension system comprising:
- a longitudinally extending beam with opposite forward and rearward ends, the axle is connected to the beam intermediate the beam forward and rearward ends, the rearward end of the beam is operatively connected to the chassis for limited vertical movement of the beam rearward end relative to the chassis;
- a spring is connected between the forward end of the beam and the chassis where the spring is connected to the beam forward of the axle;
- and,
- a radius rod having longitudinally opposite forward and rearward ends is connected between the beam and the chassis, with the radius rod rearward end connected by a pivoting connection to the beam forward end and the radius rod forward end connected by a pivoting connection to the chassis.

A suspension system for a vehicle, the suspension system comprising:
- a beam having a rearward end operatively connected to the vehicle for vertical movement of the beam rearward end relative to the vehicle, the beam extending from its rearward end toward a forward end of the vehicle to an axle of the vehicle connected to the beam, and the beam extending from the axle toward the forward end of the vehicle to a spring connected to the beam, the spring operatively connecting the beam to the vehicle;
- and,
- a radius rod having a rearward end connected to the beam by a pivoting connection for pivoting movement of the radius rod rearward end relative to the beam, and the radius rod having a forward end connected to the vehicle by a pivoting connection for pivoting movement of the radius rod forward end relative to the vehicle.
A suspension system for a vehicle, the suspension system comprising:
- a beam having a rearward end operatively connected to the vehicle for movement of the beam rearward end relative to the vehicle, the beam extending from its rearward end toward a forward end of the vehicle to an axle of the vehicle connected to the beam and to a spring connected between the beam and the vehicle;
- the axle connected to the beam is spaced forwardly of the beam rearward end and the spring connected to the beam is spaced forwardly of the axle;
- and a radius rod having opposite forward and rearward ends is connected between the vehicle and the beam with the radius rod forward end connected to the vehicle by a pivoting connection and the radius rod rearward end connected to the beam forward of the axle by a pivoting connection.
