摘要： The invention relates to a sensor assembly (10) for detecting rotation of a shaft about an axis of rotation (12), said sensor assembly having a housing (24) in which at least one magnetic field sensor (14) is arranged. The at least one magnetic field sensor (14) is designed to acquire a variation in a magnetic field generated by a magnet device (16) in the sensor assembly (10), which variation is associated with the rotation of the shaft about the axis of rotation (12). A shield device (30) arranged on the housing (24) is provided to shield the at least one magnetic field sensor (14) from the surroundings (28) of the sensor assembly (10). The shield device (30) can be removed from the housing (24), with the shield device (30) being retained on the housing (24) by means of a latching connection.

摘要： A torque sensor device for detecting a torque applied to a steering shaft of a motor vehicle is disclosed. The torque sensor device includes a magnetic arrangement, a stator arrangement, a flux guide arrangement, and a magnetic sensor arrangement comprising at least one magnetic sensor. The magnetic arrangement is configured to generate at least one magnetic field. The flux guide arrangement includes at least one first flux guide and a second flux guide. The first flux guide and the second flux guide each include at least one transmission surface. The at least one transmission surface of the first flux guide and the at least one transmission surface of the second flux guide lie opposite each other in such a way that they form an axial gap between them in which at least one magnetic sensor of the magnetic sensor arrangement is able to be arranged.

摘要： The invention relates to a stator holder (11) for a torque sensor device for sensing a torque applied to a shaft, in particular for sensing a torque applied to a steering shaft of a motor vehicle, and to a stator assembly (20) with such a stator holder (11), a method for assembling such a stator assembly (20), a torque sensor device with such a stator holder (11) and a motor vehicle with such a torque sensor device. The stator holder (11) has a receiving region (12) extending in the axial direction along an axis of rotation of the stator holder (11) and a fastening region (13) which, in a functional use state, is adjacent to the receiving region (12) in the axial direction and extends in the axial direction along the axis of rotation of the stator holder (11), wherein the receiving region (12) is designed for receiving a first stator element (14A) and a second stator element (14B) on the stator holder (11), and wherein the fastening region (13) has a fastening sleeve (13A) for the fastening of the stator holder (11) on the shaft for rotation therewith. The receiving region (12) and the fastening region (13) are formed here by separate components and/or separate assemblies.

摘要： A torque sensor device (10) for detecting a torque applied to a shaft, and a method for determining a torque applied to a shaft by means of a torque sensor device (10), to a stator and to a stator arrangement (11) for a torque sensor device (10) are disclosed. The torque sensor device (10) has a magnetic arrangement, a stator arrangement (11) and a magnetic sensor arrangement (13), wherein the magnetic arrangement and the stator arrangement (11) are configured and arranged relative to each other in such a manner that, by means of a relative movement between the magnetic arrangement and the stator arrangement in the circumferential direction, a first magnetic flux (F1) with a first magnetic flux direction and a second magnetic flux (F2) with a second flux direction opposite to the first flux direction can be generated, wherein the magnetic sensor arrangement (13) comprises a first magnetic sensor (13A) for detecting the first magnetic flux (F1) and a second magnetic sensor (13B) for detecting the second magnetic flux (F2).

摘要： The invention relates to a sensor device (100) having an incremental sensor unit (40, 40′, 40″) for a shaft rotatable about a rotational axis, in particular for a steering shaft of a motor vehicle, wherein the incremental sensor unit (40, 40′, 40″) is designed to acquire at least one defined rotational angle position of the shaft. The incremental sensor unit (40, 40′, 40″) comprises a transmitting element (41, 41″) and a housing-fixed receiving element (42), wherein a signal (MInk_planar) emitted by the transmitting element (41, 41″) and transmitted along a signal path is receivable by the receiving element (42) and it is recognizable on the basis of the signal (MInk_planar) received by the receiving element (42) whether the shaft is located in the defined rotational angle position (δdef) or not. If the shaft reaches the defined rotational angle position (δdef), a signal pulse can be generated. In this case, the transmitting element (41, 41″) is also arranged fixed on the housing, wherein a change of the signal (MInk_planar) can be caused by a rotational movement of the shaft. Furthermore, the invention relates to a motor vehicle having a sensor device (100).

摘要： A torque sensor device for detecting a torque applied to a shaft, includes a magnetic arrangement, a stator arrangement and a magnetic sensor arrangement. The magnetic arrangement is configured for generating at least one magnetic field. A magnetic flux can be generated in the stator arrangement. The magnetic arrangement and the stator arrangement are movable relative to each other in the circumferential direction. The magnetic arrangement and the stator arrangement are arranged relative to each other so that, by a relative movement between the magnetic arrangement and the stator arrangement in the circumferential direction about a center axis of the torque sensor device, a first magnetic flux with a first magnetic flux direction and a second magnetic flux with a second flux direction opposite to the first flux direction can be generated in the stator arrangement.
