Abstract
The invention relates to a holding ring for seal bellows on a track rod or shank of a universal pivot member of motor vehicles. The ring comprises a rubber or another material having comparable properties, and, secured against axial displacement, but rotatably mounted on the track rod. The holding ring is, at least on a surface area in contact with the track rod, supplied with a hardened, smoothed molecular structure. This alteration of the molecular structure is achieved preferentially by chlorination.
Claims4
A holding ring for seal bellows of a track rod of a motor vehicle comprising a track rod, a ring of elastic material having an interior contact surface with an altered molecular structure and secured against axial displacement on said track rod, but being rotatable relative to said track rod, said track rod having a track rod surface in contact with said interior contact surface of said holding ring which has a hardened, smooth, molecular structure.
A seal bellows mounting for a universal joint, including a link pin having a ball head which is pivotally mounted and a shank portion having an annular recess, a holding ring of elastic material having an interior surface with an altered molecular structure rotatably supported on the recess of said shank portion wherein the surface of said ring has a hardened, smooth molecular structure.
