Abstract

An arrangement of an angle measurement device on the chassis of a vehicle. The chassis includes a control arm ( 1 ) and a pivot bearing ( 2 ) with a pivot axis. The control arm ( 1 ) pivots about the pivot axis and the angle measurement device has a sensor ( 3 ) and a signal emitter. The sensor ( 3 ) is arranged on the control arm ( 1 ), in the area of the pivot axis, and the signal emitter is arranged on the pivot bearing ( 2 ).

First claim

The invention claimed is:

1. An arrangement of an angle measurement device on a chassis of a vehicle, the chassis having a control arm and a pivot bearing with a pivot axis,
the control arm being pivotable about the pivot axis, the control arm having a recess that extends perpendicular to the pivot axis, and the recess has axially opposite sides,
the angle measurement device having a sensor and a signal emitter,
the sensor being arranged, on the control arm, in an area of the pivot axis, the sensor being fixed within the recess between the axially opposite sides of the recess, and
the signal emitter being arranged on the pivot bearing.

2. The arrangement according to claim 1 , wherein the control arm has, on a bearing side, an annular eye with a receiving opening for the pivot bearing.

3. The arrangement according to claim 2 , wherein the eye has an outer surface, and the recess being a depression within the outer surface, and the axially opposite sides of the recess being parallel guiding surfaces, and the sensor is arranged within the recess and fixed to the outer surface.

4. The arrangement according to claim 3 , wherein the recess further has an open side in which the sensor is inserted into the recess and is guided laterally between the guiding surfaces and held.

5. The arrangement according claim 1 , wherein the pivot bearing is in a form of a spherical sleeve joint with a sleeve having a spherical portion.

6. The arrangement according to claim 5 , wherein the signal emitter is accommodated in the spherical portion of the sleeve.

7. The arrangement according to claim 5 , wherein the signal emitter consists of a plurality of permanent magnets that are arranged in the sleeve and spaced from each other around a circumference of the pivot bearing.

8. The arrangement according to claim 1 , wherein the signal emitter is in a form of a permanent magnet.

9. The arrangement according to claim 8 , wherein the permanent magnet is in a form of a cylinder with a cylinder axis, which is arranged in a radial direction relative to the pivot axis.

10. The arrangement according to claim 8 , wherein the signal emitter is in a form of a ring magnet.

11. The arrangement according to claim 1 , wherein the sensor is a Hall sensor.

12. An arrangement of an angle measurement device on a chassis of a vehicle, the arrangement comprising:
a control arm of the chassis having an annular eye with a receiving opening receiving a pivot bearing, the pivot bearing defining a pivot axis about which the control arm is pivotable relative to the pivot bearing, the annular eye having a radially outer surface with a recess formed therein, the recess having axially opposite guiding surfaces that extend perpendicular to the pivot axis; and
the angle measurement device having a sensor and a signal emitter, the sensor being fixed axially within the recess between the guiding surfaces and the signal emitter being arranged in a radially outer surface of the pivot bearing, and the sensor detecting signals emitted by the signal emitter to facilitate measuring movement of the control arm relative to the pivot bearing.
