End cap assembly for air spring

Abstract From the Canadian patent

An air spring formed by a pair of spaced end members and an intervening tubular elastomeric sleeve having internal reinforcing cords forms a fluid pressure chamber therebetween for mounting between spaced portions preferably of a vehicle to provide damping and to absorb road shock on the vehicle. Each of the end members has an end cap and a clamp ring provided with annular mating surfaces. The clamp ring is formed with an annular convex projection which extends into a larger annular concave recess formed in the end cap and when the ring and end cap are snapped axially together two annular radially spaced areas of the sleeve are placed in compressive shear to provide a secure clamping …
