Embodiment Construction

[0020] The ball joint shown in Figure 1 is basically composed of a joint housing 1, a bearing bush 2 located in the inner cavity of the joint housing, a joint pin 3 installed in the bearing bush, a sealing ring 4 and a sealing cup 5 composition. Here, the joint pin 3 has a ball head 6 and a journal-shaped partial area 7 , wherein the journal-shaped partial area 7 is in turn divided into a conical mounting section 8 and a threaded section 9 . After assembly of the entire ball joint, especially the cavity 10 between the sealing cup 5 and the joint pin 3 as well as the outer side of the sealing cup 5 and the journal-like partial area 7 are protected from mechanical loading during transport Not to be polluted and damaged. For this purpose, a ball joint protective cover 11 is assigned to the ball joint after it has been assembled. In the illustrated embodiment, the ball joint boot 11 has three hollow cylindrical sections 12 , 13 and 14 . The hollow cylindrical parts have differe...

Abstract

A protective cap for a balljoint is disclosed, for covering the peg-shaped partial region (7) of a ready-assembled balljoint, comprising at least two hollow cylindrical sections (12, 13) of differing diameter adjacent to each other in the axial longitudinal direction of the balljoint protective cap (11), whereby the section (12) with greater diameter is arranged on the balljoint protective cap (11) for mounting onto the joint housing (1). According to the invention, an improved protection of the ready-assembled balljoint with a mounted protective cap (11) may be achieved, whereby the above comprises a transition region (16), at the joint of the two hollow cylindrical sections (12, 13), running essentially perpendicular to the axial longitudinal direction of the balljoint protective cap (11). The size of the diameter of the smaller hollow cylindrical section (13) of the balljoint protective cap (11) is only slightly larger than the size of the covered spherical housing section (8) of the joint pin (3) in the balljoint. By means of the above particular arrangement, a displacement of the sealing bellows (5) on the balljoint in the direction of the arrow (P) on mounting the balljoint protective cap on the peg-shaped partial region of the balljoint can be achieved, whereby the contact pressures in the region of the contact surfaces between the sealing bellows (5) and joint pin (3) are increased.

Description

technical field [0001] The invention relates to a ball joint protective cover for covering a journal-like partial area of ​​an assembled ball joint during the time period between the manufacture of the ball joint and its mounting. Background technique [0002] A ball joint using such a ball joint boot generally consists of a joint housing and a joint pin accommodated within the joint housing by means of a bearing shell. The joint pin consists of a spherical bearing surface and a journal-like partial region extending on the bearing surface in the longitudinal direction of the joint pin and protruding from the joint housing in the assembled state of the ball joint . On this journal-shaped partial area there is usually a conical mounting section for fastening the ball joint to another component, for example a chassis component of a car, and a thread which is usually provided with an external thread for fastening part. A further component of this ball joint is a sealing cup w...
