A ball joint comprised of a ball with a shank, a socket having slots on the open side thereof, a steel ring with a lever for accommodating the ball joint, and a clamping mechanism which is fitted as a one-piece unit to the socket, said clamping unit being adapted to also effect clamping of the upper portion of the socket and to afford force and form-locking stabilization thereof. The clamping unit for effecting biasing in axial direction of the socket with the steel ring forming the housing of the ball joint is in the form of a knee-lever mechanism. This mechanism includes hook-like members which are arranged on the socket, said hook-like members being linked with a centrally disposed and axially displaceable thrust member. The thrust member serves as a manipulating means for actuating the knee-lever mechanism.

A ball joint, especially for motor vehicles, comprising a spherical ball having a shank, a socket having an opening on one side and axially extending slots for receiving and engaging said spherical ball, a housing comprising a metal ring surrounding said socket and having one end engaging an abutmen

A ball joint, especially for motor vehicles, comprising a spherical ball having a shank, a socket having an opening on one side and axially extending slots for receiving and engaging said spherical ball, a housing comprising a metal ring surrounding said socket and having one end engaging an abutment means carried by said socket adjacent said one side thereof, and a bracing and clamping mechanism formed integral with said socket and adjacent said spherical ball at its end remote from its shank for retaining said socket within said steel ring and preventing relative axial displacement relative thereto, the improvement being that said bracing and clamping mechanism includes a plurality of annularly spaced hook-like members integrally hinged at one end to said socket via first hinges, a plurality of bracing members being integrally hinged at their outer ends with the other ends of adjacently located ones of said hook-like members via second hinges and a thrust member integrally hinged with the inner ends of said bracing members via third hinges, said bracing and clamping mechanism being movable between an unclamped position in which said third hinges have their pivot axes spaced further from said spherical ball than the axes of said second hinges and said hook-like members are disengaged from said metal ring at its other end to permit disassembly of said ball joint and a clamped position in which said hook-like members engage said other end of said steel ring and said third hinges have their axes located closer to said spherical ball than the axes of said second hinges by pushing said thurst member of said bracing and clamping mechanism toward said spherical ball whereby said bracing and clamping mechanism functions as an over-center toggle mechanism to retain said socket in place on the metal ring and to biasingly hold said socket in engagement with said spherical ball.
