Definitions

  • the invention relates to an arrangement for connecting a suspension link to a wheel carrier on a motor vehicle by means of a ball and socket joint, the link having a handle eye, the ball sleeve joint a ball sleeve and the wheel carrier two bearing eyes, wherein on the handlebar eye a sensor and the ball sleeve a signal generator are arranged , which form an angle measuring device, and wherein the ball sleeve is clamped by a bolt with the bearing eyes.
  • a ball sleeve joint which connects a handlebar of a chassis with a wheel.
  • the ball sleeve which is arranged between two bearing lugs of the wheel carrier is clamped by a bolt between the bearing eyes.
  • the ball sleeve joint has a joint housing, which is connected directly to the handlebar, preferably a wishbone.
  • the ball and socket joint is equipped with a sensor arrangement for detecting the position of the link relative to the wheel carrier.
  • a first sensor preferably a magnetic field sensor is arranged in the joint housing, while a second sensor element, preferably a permanent magnet is arranged as a signal generator in the ball sleeve.
  • the handlebar results in a change of the magnetic field, whereby a signal is generated in the magnetic field sensor, which is representative of the angular position.
  • the problem may arise that the signal transmitter - as seen in the circumferential direction - occupies a position which is outside of the magnetically sensitive region of the magnetic field sensor.
  • An object of the invention is to further improve the subject matter of the earlier application, in particular with regard to the functional installation of the ball and socket joint with integrated position sensor.
  • the invention comprises the features of claim 1. Advantageous embodiments will be apparent from the dependent claims.
  • an anti-rotation device for fixing a defined angular position between the ball sleeve and the wheel carrier is provided between the ball sleeve and the wheel carrier.
  • the anti-rotation is basically such that at least a first positive locking element on the ball sleeve and at least one second positive locking element on the wheel or the bearing eyes are arranged, which are brought into engagement during assembly of the ball sleeve. This ensures that the ball sleeve, which is arbitrarily rotatable during assembly of the ball sleeve joint, is brought into a defined angular position in which it is fixed.
  • At least one end face of the ball sleeve has a flattening on the circumference and at least one end face of the bearing eyes a corresponding edge, wherein the flattening and the edge are engaged with each other, d.
  • a rotation of the ball sleeve relative to the bearing eyes or the wheel is not possible - in this angular position of the bolt is inserted through the through holes of the bearing eyes and the ball sleeve and clamped.
  • the secured against rotation relative to the wheel carrier ball sleeve is thus clamped in the defined angular position. This ensures that the sensor on the handlebar eye "sees" the signal transmitter or the individual magnets and thus can generate a signal as a result of a change in the magnetic field in each relative movement between the arm and ball sleeve.
  • the flattening and the corresponding edge have a straight course in the tangential direction with respect to the longitudinal axis of the ball sleeve.
  • a disc is arranged and fixed on at least one end face of the ball sleeve, wherein the flattening is arranged on the circumference of the disc.
  • the disc is preferably pressed onto a frontal collar, so that the length of the ball sleeve does not change.
  • two discs, one on each end face, are provided. The anti-rotation device according to the invention can thus be retrofitted to a standard ball sleeve joint without much effort.
  • the signal generator is designed as a cylindrical magnet whose poles in the radial direction with respect to
  • Pivot axis and / or the longitudinal axis of the ball and socket joint are aligned. As mentioned above, preferably only one magnet is arranged on the circumference, which provides cost advantages.
  • the signal transmitter or the magnet in the longitudinal direction of the link which generally corresponds to the direction of force in the handlebar, or arranged transversely to the longitudinal direction of the ball sleeve. These two angular positions are preferred depending on the load of the handlebar.
  • 1 is a first 3D representation of a linkage of a link to a
  • FIG. 2 is a second 3D representation of the articulation of the link according to Figure 1 in a different perspective
  • Fig. 3 is a view in the axial direction on the end face of a first Bearing eye with a tangential edge
  • Fig. 4 is a view in the axial direction on the end face of a second bearing eye with tangential edge
  • Fig. 5 is an axial section in the region of a pressed onto a ball sleeve
  • FIGS. 1 and 2 show, in a first and a second 3D illustration, the connection of a link 1 to a wheel carrier 2 as a detail of a chassis for a motor vehicle in different perspectives.
  • the link 1 which has an annular handlebar eye 1a, is connected via a ball sleeve joint 3, which is received in the handlebar eye 1a and therefore only partially visible, via two bearing lugs 4, 5 and a bolt 6 with the wheel carrier 2.
  • a ball sleeve joint 3 As regards the structure of the ball and socket joint 3, reference is made to the above-mentioned earlier German application of the applicant with the file number 10 2017 208410, the disclosure of which is fully incorporated into this application.
  • a ball sleeve 7 which extends to both sides of the handlebar 1 and is clamped between the bearing lugs 4, 5 by the bolt 6.
  • the articulation between the handlebar 1 and ball sleeve 7 has - which is not shown here - a sensor arrangement which comprises a sensor arranged on the handlebar 1a and a sensor arranged on the ball sleeve 7 signal generator, preferably in the form of a permanent magnet.
  • the ball sleeve 7 is mounted and fixed in a defined angular position, depending on the position of the signal transmitter, relative to the wheel carrier 2 or the two bearing eyes 4, 5.
  • a shoulder with a tangential edge 10 is arranged, which rests against the flattening 9.
  • the first disc 8, which is positively or frictionally connected to the ball sleeve 7 is thus prevented from twisting.
  • Fig. 3 shows a view in the axial direction, d. H. in the direction of the longitudinal axis of the ball sleeve, not shown here, on an end face 4a of the first bearing eye 4, wherein in the drawing perpendicular and tangential with respect to the longitudinal axis of the ball sleeve extending edge 10 can be seen.
  • the first disc 8 which is connected to the ball sleeve 7 (Fig. 1, 2), shown with the tangential flattening 9, which is in engagement with the edge 10, d. H. attached to this.
  • the first disc 8 and thus the ball sleeve are fixed in a defined angular position.
  • Fig. 4 shows a view in the axial direction of an end face 5 a of the second bearing eye 5 with a relation to the end face 5 a projecting tangentially extending edge 10 a, which corresponds to the edge 10 in Fig. 3 and this is directly opposite in the wheel 2 in the axial direction.
  • the second disc 8a which is also connected to the ball sleeve, and has a flattening 9a, which is in engagement with the edge 10a.
  • the ball sleeve 7 with the two discs 8, 8a from top to bottom, shown in the drawing by the arrows X, between the two bearing eyes 4, 5 are used, wherein the flats 9, 9a on the edges 10, 10a slide, d. H. the ball sleeve 7 retains its angular position predetermined by the flats 9, 9a in relation to the wheel carrier 2.
  • the bolt 6 (FIG. 1), not shown here, can be inserted and braced through the bearing eyes 4, 5 and the ball sleeve 7 (FIG. The ball sleeve is thus fixed with respect to its angular position. In a wrong assembly of the bolt 6 can not be pushed through.
  • two discs a first disc 8 and a second disc 8a, attached to the ball sleeve 7.
  • a disc either the first disc 8 or the second disc 8a, to set the desired angular position.
  • Fig. 5 shows a sectional view, ie an axial section in the region of the rotation between the ball sleeve 7 and the first bearing eye 4.
  • the first disc 8 has - in the drawing on the left - the flattening 9, which is in engagement with the edge 10 and thus the angular position of the ball sleeve 7 is fixed.
  • the bolt 6 extends through the through holes of the bearing eye 4 and the ball sleeve 7.
  • the handlebar eye 1a is partially visible.
