Abstract: Apparatus for spin closing an open end of a tube of a suspension strut comprising a throughbore having a longitudinal axis; a first pair of rollers, each roller of the first pair being rotatably mounted in a bore opening into the throughbore, having a contact surface at a first predetermined angle to the longitudinal axis and which extends into the throughbore, and being biased such that the contact surface can retract from the throughbore against the action of biasing means; and a second pair of rollers, each roller of the second pair being rotatably mounted in a bore opening into the throughbore, and having a contact surface at a second predetermined angle to the longitudinal axis and which extends into the throughbore; wherein the second predetermined angle is greater than the first predetermined angle; and wherein the first pair of rollers is offset from the second pair of rollers along the longitudinal axis such that, on insertion, the open end of the tube of the suspension strut will make contact with t

Abstract: A hydraulic damper for a motor vehicle comprising a longitudinally extending tube and a separately formed steering knuckle secured to the tube, wherein the tube is formed from extruded aluminum or aluminum alloy, and the steering knuckle is formed from aluminum or aluminum alloy. The steering knuckle includes a tubular portion that overlies and is secured to a portion of the tube through the use of a groove in the tubular portion and a groove in the tube. Adhesive may be injected into the grooves to aid in securing the steering knuckle to the tube.

Abstract: A suspension strut comprising a tube substantially closed at both ends and containing fluid; a piston assembly slidably mounted in the tube and making a sealing fit therewith, the piston assembly separating a compression chamber and a rebound chamber within the tube; a piston rod attached to the piston assembly and extending through the rebound chamber and out of one end of the tube; and a rebound stop mounted on the piston rod between the piston assembly and one end of the tube, the rebound stop comprising a substantially rigid ring and an annular bumper, wherein the rebound stop is engageable with one end of the tube and with the piston assembly.
