Abstract
Disclosed is an improved air suspension that prevents damage and/or failure of a component of an air spring, such as an air sleeve, by unwanted force or moment, such as rotational torque, applied to the air spring during vehicle traveling. The air suspension includes a damper including a cylinder and a piston rod, an air spring to which a canister and an air piston are hermetically connected via an air sleeve, an upper mount which secures the piston rod and the canister to a vehicle frame, a first bearing disposed at a connecting portion between the upper mount and the piston rod, and a second bearing disposed at a connecting portion between the air piston and the cylinder. Each of the first and second bearings is a thrust bearing.
