Torque-sensor device and method for assembling a torque-sensor device

A torque sensor device for detecting a torque applied to a steering shaft of a motor vehicle,

• wherein the torque sensor device comprises:
• a magnetic arrangement,
• a stator arrangement,
• a flux guide arrangement, and
• a magnetic sensor arrangement comprising at least one magnetic sensor,
• wherein the magnetic arrangement is configured to generate at least one magnetic field,
• wherein the flux guide arrangement comprises at least one first flux guide and a second flux guide,
• wherein the first flux guide and the second flux guide each comprise at least one transmission surface,
• wherein 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 one another 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,
• wherein the magnetic arrangement and the stator arrangement are movable relative to each other in the circumferential direction about a center axis of the torque sensor device as a result of a torque being applied, in such a way that a relative movement between the magnetic arrangement and the stator arrangement in a circumferential direction enables a magnetic flux to be generated in the stator arrangement, and
• wherein the torque sensor device comprises a plurality of assemblies, including at least one first pre-assembled assembly with a first housing part and a second pre-assembled assembly with a second housing part,
• wherein the first pre-assembled assembly comprises at least the first housing part, the stator arrangement, and at least one magnetic sensor of the magnetic sensor arrangement,
• wherein the second pre-assembled assembly comprises at least the second housing part, the first flux guide and the second flux guide, and
• wherein the second housing part is pushable or pluggable onto the first housing part or is at least partially pushable or insertable together with the first housing part,
• wherein, during the at least partially pushing or inserting together, at least one magnetic sensor is introducible into the gap between the transmission surfaces of the first flux guide and the second flux guide in such a way that, in a functionally assembled state of the torque sensor device, in which at least the first pre-assembled assembly and the second pre-assembled assembly are functionally assembled, a magnetic flux generated in the stator arrangement is detectable by the magnetic sensor.
