Definitions
- the higher capacity specialized air spring must be overinflated to a full rebound position of about nine inches from the ride height position, as compared to the full rebound position of about four and one-half inches for an air spring used in a roadway-only trailer air-ride axle/suspension system.
- such compression springs do eliminate the need for shock absorbers in the axle/suspension system, since the spring is active at all times and provides suspension damping during roadway use of the trailer.
- Another objective of the present invention is to provide such a lift assembly having increased lifting efficiency over prior art lift assemblies, but which also minimizes the force required by the air spring to lower the axle/suspension system to the rebound or transfer position.
- An additional objective of the present invention is to provide such a lift assembly which provides suspension damping for over-the-road use of the trailer and eliminates the need for suspension assembly shock absorbers.
- Still another objective of the present invention is to provide such a lift assembly which is economical, lightweight, durable in use, easy to install, maintain, and replace.
