摘要： A method of manufacturing is disclosed for the installation of a one piece damper member for retaining the midpoint of a torsion tube on the torsional axis of a channel-shaped cross beam vehicle rear axle. The damper member is formed during the axle assembly line advancement by injecting a first mass of hardenable urethane paste material into a side gap portion and arcuate shaped central gap portion of a D-shaped recess defined intermediate the channel interior and the tube. A second mass of the urethane paste material is injected into the remaining side gap portion and channel upper open end space. As an adjunct to the axle being advanced through assembly line washing, wax coating and heat treating operations the first and second masses coalesce and attain an accelerated final curing of the tube retaining damper member.

摘要： A damper member is disclosed for retaining a torsion rod within cross-beam inverted channel-shaped rear axle. The damper member is normally U-shaped in cross-section having an upwardly opening central bore defined by vertically extending leg portions and a base portion. Upon the damper member being compressed into a D-shaped clearance between the channel and the rod its section is transformed for a U-shape to a C-shape. The unique design of the damper member enables it to be lockingly retained under pressure in the D-shaped clearance.
