Abstract
An arrangement of at least one sensor track-scanning rotor position sensor (1, 1 A) of an electric machine (EM) in a hybrid transmission housing (2) that includes a torque converter (3) and a housing-affixed oil supply plate arrangement is provided. The rotor position sensor (1, 1 A) is attached on an oil-supply-plate side, and a sensor ring (8), as a sensor track, is attached on a converter side. A hybrid transmission housing (2) including the arrangement is also provided.
Claims12
A sensor system in a hybrid transmission housing (2) that includes a torque converter (3) and a housing-affixed oil supply plate arrangement, comprising:
- at least one sensor track-scanning rotor position sensor (1, 1 A) attached to the oil supply plate arrangement such that the at least one sensor track-scanning rotor position sensor (1, 1 A) is rotationally fixed on the oil supply plate arrangement;
- and
- a sensor ring (8) configured as a sensor track, the sensor ring (8) attached to the torque converter (3) such that the sensor ring (8) is coupled to the torque converter (3).
A sensor system in a hybrid transmission housing (2) that includes a torque converter (3) and a housing-affixed oil supply plate arrangement, comprising:
- at least one sensor track-scanning rotor position sensor (1, 1 A) attached to the oil supply plate arrangement;
- and
- a sensor ring (8) configured as a sensor track, the sensor ring (8) attached to the torque converter (3),
- wherein the oil supply plate arrangement comprises a centering plate (6) and an intermediate plate (7), the centering plate (6) arranged on a torque converter side in the hybrid transmission housing (2), the centering plate (6) connected to the intermediate plate (7), and
- wherein the rotor position sensor (1, 1 A) is integrated into the oil supply plate arrangement and is arranged between the centering plate (6) and the intermediate plate (7).
