Abstract
This suspension strut has upper and lower air sleeves which when pressurized with air provide the air spring suspension of a vehicle and which are axially offset from one another so that a force couple is formed that provides a moment which counteracts the moment resulting from the tire contact patch acting at a distance from the lower ball joint. With the tire contact moment neutralized, the side loads on the bearing and other sliding components of the strut are eliminated or sharply reduced to increase efficiency of strut operation and enhance strut durability.
