Embodiment Construction

[0030] figure 1 A side view of a preferred embodiment of an axial ball joint 1 according to the invention is shown. The axial ball joint 1 firstly comprises a housing 2 which has a housing pin 3 on its underside. In the housing 2 is located a bearing shell, which is not visible in this side view, into which a joint ball 4 , which is only partially visible, is inserted with a joint pin 5 . The joint pin protrudes from the housing 2 through an opening in the housing 2 . On the underside of the housing 2 , which is opposite the opening of the housing 2 through which the joint pin 5 passes, the annular damping element 7 is inserted on the outside into a shoulder or shoulder which is not visible here.

[0031] If the axial ball joint 1 constructed according to the invention is used in a steering gear, the maximum swivel amplitude can be limited by the mechanical impact of the housing 2 . Here, the damping element 7 prevents severe impacts. In general, the steering gear housing ...

Abstract

The invention relates to an axial ball joint (1) in particular for use in a steering gear including a housing (2), open on one side, with a housing pin (3) arranged up front, a ball joint (4) with a pivot pin (5) and a bearing (6) which is arranged between housing (2) and ball joint (4), wherein the housing (2) has at least one elastic damping element (7) for impact damping on the side of the housing equipped with the housing pin (3).

Description

technical field [0001] The invention relates to an axial ball joint (Axialkugelgelgelenk) for use in particular at a steering gear (Lenkgetriebe), which comprises a one-sided open Housing, joint ball with joint pin and bearing shell arranged between housing and joint ball. Background technique [0002] Similar axial ball joints are generally known and are used in particular in the field of vehicle steering systems, wherein such vehicle steering systems each have an end limit in the region of maximum deflection. If the steering gear is guided into the region of the end limit, the mechanical limitation of the steering swing (Lenkungsausschalg) leads to a strong steering impact (Anschlag) in the end region. This problem has been known for a long time, and attempts have therefore been made to develop collision dampening for these steering gears. For example, reference is made in this regard to the publications EP 1 122 149 A1, US 5,788,009, DE 600 01 626 T2, DE 697 25 931 T2, ...
