Patent ID: 7377160

Claim:
A sensor arrangement for a tachometric sensor of an automatic transmission of a motor vehicle, the sensor arrangement comprising: a sensor housing ( 3 ) containing a tachometric sensor, and a module carrier ( 2 ), a first portion of the sensor housing ( 3 ) being located in and axially moveable in a sensor housing opening in a transmission housing ( 4 ), and a second portion of the sensor housing ( 3 ) being located in and axially moveable in the module carrier ( 2 ), the sensor housing ( 3 ) being non-rotationally fixed in at least one of the module carrier ( 2 ) and the sensor housing opening in the transmission housing ( 4 ) by a guide, a first detent ( 6 ) surface located at and circumferential to the sensor housing opening in the transmission housing ( 4 ) and facing toward and coaxial with the module carrier ( 2 ), the sensor housing ( 3 ) having a second detent surface ( 8 ) circumferential to the sensor housing ( 3 ) and facing toward and coaxial with the sensor housing opening in the transmission housing ( 4 ), a resilient apparatus ( 5 ) acting between the sensor housing ( 3 ) and the module carrier ( 2 ) to generate a resilient prestress force by which the sensor housing ( 3 ) is resiliently and axially biased toward the transmission housing ( 4 ) so that the second detent surface on the sensor housing ( 3 ) bears against the first detent ( 6 ) surface, on the transmission housing ( 4 ), whereby the sensor housing ( 3 ) is axially positioned in the sensor housing opening at a predetermined axial position that is determined by the locations of the first and second detent surfaces ( 6 , 8 ).
