Abstract
The invention relates to an elastomeric joint, comprising a housing with a through-opening which extends axially along the longitudinal axis of the elastomeric joint, a pivot pin which extends through the through-opening of the housing, an elastomeric body which is fastened to the pivot pin and is arranged radially between the pivot pin and the housing, and with at least one supporting ring which is fastened to the elastomeric body on one end face of the through-opening, wherein a wire ring locks the supporting ring with respect to the housing, with the result that the pivot pin is held in the housing in an axially secured manner.
Claims14
An elastomeric joint configured for chassis components of motor vehicles, comprising:
- a housing comprising a through-opening which extends axially along a longitudinal axis of the elastomeric joint and has opposing end faces,
- a pivot pin which extends through the through-opening of the housing,
- an elastomeric body which is fastened to the pivot pin and is arranged radially between the pivot pin and the housing,
- at least one supporting ring which is mounted to the elastomeric body at a respective one of the end faces of the through-opening, at least one of the supporting rings having a linearly tapered annular contact surface inclined by an angle relative to the longitudinal axis and outwardly facing a respective one of the end faces, and
- a locking element being in contact with the contact surface of the at least one supporting ring and locking the at least one supporting ring with respect to the housing so that the pivot pin is held in the housing in an axially secured manner,
- wherein an inner circumferential surface of the housing comprises a groove whose contour substantially corresponds to a cross-section of the locking element so that the locking element fits in the groove,
- wherein the locking element is formed from a split wire ring,
- wherein an outer surface of the wire ring matingly engages the groove and an inner surface of the wire ring seats upon the contact surface such that the wire ring lies within a plane perpendicular to the longitudinal axis, and
- wherein the angle of the contact surface is selected such that in the event of an axial force acting on the pivot pin in an outward direction from the housing, the wire ring experiences a resulting outward force relative to the longitudinal axis perpendicular to the angle of the contact surface that always points toward the groove to thereby radially expand and press the wire ring into the groove so that the wire ring is prevented from tilting or coming loose.
