Embodiment Construction

[0026] Figure 1aA ball joint 1 with a housing 2 and a ball pin 3 is shown. The ball pin 3 has a ball joint 4 , wherein the ball joint 4 has a flattened area 5 . Opposite this flattened area 5 , the sensor 6 is arranged on the housing wall 7 . Sensor 6 is a distance sensor. The ball pin 3 also extends out of the housing 2 in the axial direction A through the opening 8 . The ball joint 1 is shown in three different positions L, M, N. In the first position L, there is a negative inclination angle −α between the ball pin 3 and the housing 2 . In the second position M there is an angle of inclination α between the ball pin 3 and the housing 2 of 0 degrees, and in the third position N there is a positive angle of inclination +α between the ball pin 3 and the housing 2 . The axial direction A of the ball pin 3 is indicated by a straight line A in each case. If the inclination angle α between the ball pin 3 and the housing 2 is 0 degrees, as in Figure 1a As shown in the second...

Abstract

The invention relates to a ball joint (1) for a vehicle, comprising a housing (2) and a ball stud (3) extending in an axial direction (A) and comprising a ball joint (4), which is pivotably moveably mounted in the housing (2) with its ball joint (4) and extends out through an opening (8) of the housing (2), and at least one sensor (6) which functions to detect a tilt angle (alpha) between the ballstud (3) and the housing (2), wherein the ball joint (4) has a flattened area (5), and wherein the at least one sensor (6) is a distance sensor which is arranged on a wall (7) of the housing (2) andlies opposite the flattened area (5) of the ball joint (4) in order to detect a distance (d) with respect to the flattened area (5) and to derive the tilt angle (alpha) from this.

Description

technical field [0001] The invention relates to a ball joint for a vehicle having a housing and a ball pin extending in the axial direction and comprising a joint ball, the ball pin being pivotably mounted with its joint ball in the housing and passing through An opening of the housing extends, and the ball joint has at least one sensor for detecting the angle of inclination between the ball pin and the housing. Background technique [0002] Ball joints of this type are already known from the prior art. For example, German publication DE 10350640 B4 describes a ball joint for motor vehicles comprising a housing with a recess, a ball pin with a pin and a joint sphere, the ball pin being rotatably and pivotally supported with its joint sphere in the notch of the housing. The pin extends through an opening provided in the housing and a fold seal is provided arranged between the housing and the pin. Furthermore, a multi-part measuring assembly is known, which has at least one...
