Abstract
An arrangement for detecting a torque on a machine element includes a sleeve having a magnetized region and being arranged on the machine element. The arrangement further includes a magnetic field sensor, which is arranged opposite the sleeve, and an intermediate sleeve. The intermediate sleeve is arranged coaxially between the machine element and the sleeve and is connected to the sleeve for conjoint rotation. The intermediate sleeve includes a radially inwardly directed elevation at each of two end regions thereof. The elevations abut the machine element and connect to the machine element for conjoint rotation.

An arrangement for detecting a torque on a machine element using a magnetic field sensor disposed near the arrangement, the arrangement comprising:
- a sleeve having a magnetized region and being arranged on the machine element, wherein the magnetized region includes a plurality of magnetic tracks lying parallel relative to each other and parallel relative to a central axis of the sleeve;
- and
- an intermediate sleeve arranged coaxially between the machine element and the sleeve and connected to the sleeve for conjoint rotation, the intermediate sleeve having a radially inwardly directed elevation at each of two end regions thereof, wherein the elevations abut the machine element and connect the intermediate sleeve to the machine element for conjoint rotation, wherein the intermediate sleeve is a non-magnetic material.
A vehicle comprising:
- a shaft;
- a sleeve having a magnetized region and being arranged on the shaft, wherein the magnetized region includes a plurality of magnetic tracks lying parallel relative to each other and parallel relative to a central axis of the sleeve;
- and
- an intermediate sleeve arranged coaxially between the shaft and the sleeve and connected to the sleeve for conjoint rotation, the intermediate sleeve having a radially inwardly directed elevation at each of two end regions thereof, wherein the elevations abut the shaft and connect the intermediate sleeve to the shaft for conjoint rotation, wherein the intermediate sleeve includes:
- a recess axially between the two end regions and arranged on a radial outer surface of the intermediate sleeve and extending only partially into the radial outer surface, the recess being aligned with the magnetized region of the sleeve and defining a gap arranged between the intermediate sleeve and the magnetized region of the sleeve.
An arrangement for detecting a torque on a machine element using a magnetic field sensor disposed near the arrangement, the arrangement comprising:
- a sleeve having a magnetized region and being arranged on the machine element, wherein the magnetized region includes a plurality of magnetic tracks lying parallel relative to each other and parallel relative to a central axis of the sleeve;
- and
- an intermediate sleeve arranged coaxially between the machine element and the sleeve and connected to the sleeve for conjoint rotation, the intermediate sleeve having a radially inwardly directed elevation at each of two end regions thereof, wherein the elevations abut the machine element and connect the intermediate sleeve to the machine element for conjoint rotation.
