Abstract

A transmission position sensor body assembly configured to be securely attached to a transmission housing includes a sensor body housing, a cap member and compression limiters. The sensor body housing has a central rim and a pair of outer receiving lobes that define a corresponding pair of bores. The cap member has a central body portion including integrally formed outer ears extending therefrom. The cam member is coupled to the sensor body. The compression limiters are coupled to the cap member at the respective outer ears and that extend through the bores of the sensor body housing. Fasteners are received through respective compression limiters. Clamping forces are transferred onto the cap member during the tightening of the fasteners to the transmission housing without acting on the sensor body housing.

First claim

The invention claimed is:

1. A transmission position sensor body assembly configured to be securably attached to a transmission housing, the transmission position sensor body assembly comprising:
a sensor body housing having a central rim and a pair of outer receiving lobes that define a corresponding pair of bores;
a cap member having a central body portion including integrally formed outer ears extending therefrom, the cap member being coupled to the sensor body;
compression limiters coupled to the cap member at the respective outer ears and that extend through the bores of the sensor body housing; and
wherein fasteners are received through the respective compression limiters and wherein clamping forces are transferred onto the cap member during tightening of the fasteners to the transmission housing without acting on the sensor body housing.

2. The transmission position sensor body assembly of claim 1 , further comprising:
an O-ring positioned between the cap member and the transmission housing and that forms a seal between the cap member and the transmission housing.

3. The transmission position sensor body assembly of claim 1 wherein the compression limiters are over-molded to the cap member.

4. The transmission position sensor body assembly of claim 1 wherein the compression limiters are pressed into the cap member.

5. The transmission position sensor body assembly of claim 1 wherein the cap member and the sensor body are coupled together by a laser weld.

6. The transmission position sensor body assembly of claim 1 wherein the sensor body housing further comprises an electrical connector.

7. The transmission position sensor body assembly of claim 1 wherein the pair of bores in the sensor body housing have inner diameters that are greater than corresponding outer diameters of the compression limiters such that the compression limiters float within the respective bores.

8. The transmission position sensor body assembly of claim 1 wherein the sensor body housing and the cap member are formed of rigid plastic and the compression limiters are formed of metal.

9. The transmission position sensor body assembly of claim 1 wherein the cap member further includes a recessed center section having an outer boundary defined by an outer lip and an inner boundary defined by a raised central wall.

10. The transmission position sensor body assembly of claim 9 wherein the outer lip extends to a common plane as the outer ears.

11. A transmission position sensor body assembly configured to be securably attached to a transmission housing, the transmission position sensor body assembly comprising:
a sensor body housing having a central rim and a pair of outer receiving lobes;
a cap member having a central body portion including integrally formed outer ears extending therefrom, the cap member including a recessed center section having an outer boundary defined by an outer lip and an inner boundary defined by a raised central wall, the cap member being coupled to the sensor body;
compression limiters coupled to the cap member at the respective outer ears; and
an O-ring configured to be received at the recessed center section and form a seal between the cap member and the transmission housing.

12. The transmission position sensor body assembly of claim 11 wherein the compression limiters are over-molded to the cap member.

13. The transmission position sensor body assembly of claim 11 wherein the compression limiters are pressed into the cap member.

14. The transmission position sensor body assembly of claim 11 wherein the outer lip extends to a common plane as the outer ears.

15. The transmission position sensor body assembly of claim 11 wherein the sensor body housing further comprises an electrical connector.

16. The transmission position sensor body assembly of claim 11 wherein the cap member and the sensor body are coupled together by a laser weld.

17. The transmission position sensor body assembly of claim 16 wherein the laser weld is a face weld.

18. The transmission position sensor body assembly of claim 11 wherein the outer ears define respective bores therein, the bores configured to receive the compression limiters.

19. The transmission position sensor body assembly of claim 18 wherein the compression limiters float within the respective bores.

20. The transmission position sensor body assembly of claim 19 wherein fasteners are received through the respective compression limiters and wherein clamping forces are transferred onto the cap member during tightening of the fasteners to the transmission housing.
