Articulated pipe joint between vehicle body and chassis - has spherical end flanges attached to axially sliding sleeves secured together by springs

摘要

The articulated pipe joint is for making a connection between the body of a vehicle and the chassis and can accommodate the relative displacements due to the vehicle suspension system. The joint has two similar end flanges (1) (2) with short tubular extensions which terminate in a convex spherical seating surface. These convex surfaces abut against matching concave surfaces formed on the ends of two sleeves. One sleeve (3) slides inside the other (4) and has a groove for a sealing ring (7). The axial movement between the selves is limited by a pin (10) in the outer sleeve which projects into a recess formed in the inner sleeve (3). The sleeves have flanges (5, 6) by which they are joined with spring loaded bolts (8, 9) to the end flanges.
