PCT No. PCT/SE95/00580 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed May 23, 1995 PCT Pub. No. WO96/26845 PCT Pub. Date Sep. 6, 1996A sealed spring suspension for a vehicle includes a threaded bearing made of a spring shackle bolt and a spring bushing; into a recess in either end of the bushing, a sealing ring is pressed, which has a resilient sealing portion with a ring or lip in radial contact with the flat sealing portions of the bolt. By virtue of the bolt thread located between these portions having flattened thread tops and thread bottoms, the ring lip is able to slide without being damaged along said bottoms when the bolt during mounting is threaded into the bushing.
