Actuating rod end connector
View Patent ↗An improved actuating rod end connector is connected with an actuating rod that extends from a turbocharger assembly actuator mechanism. The rod end connector has a body with an opening at one longitudinal end, and the actuator rod is disposed through the opening. An adjustment member is rotatably disposed within the body and has a threaded inside cavity in communication with the opening. The inside cavity is threadably engaged with a threaded outside surface of the actuator rod. The body includes an actuator rod opening disposed therethrough adjacent the adjustment member to receive a section of the actuator rod therein to facilitate contacting the actuator rod disposed within the body from outside of the rod end connector. An attachment opening is disposed through the body to facilitate attachment of the rod end connector with a linkage member, e.g., a linkage member connected with a movable member of the turbocharger.

8. The turbocharger assembly as recited in claim 1 wherein the actuator is pneumatically operated and the actuator rod is connected to a diaphragm disposed within the actuator.
9. The turbocharger assembly as recited in claim 1 further comprising a wastegate mechanism, and wherein the linkage member is attached to the wastegate mechanism.
10. The turbocharger assembly as recited in claim 1 further comprises a plurality of vanes movably disposed within the turbine housing, and wherein the linkage member is connected with the vanes.
11. An actuator mechanism used with a turbocharger assembly comprising a turbine housing having a turbine wheel disposed therein, a compressor housing having a compressor impeller disposed therein, and a center housing interposed between the turbine housing and the center housing, the actuator mechanism comprising:
an actuator comprising an actuator rod extending therefrom; and
a rod end connector attached to the actuating rod, the rod end connector comprising:
a body formed from two joined together body members and having an opening at one longitudinal end, the actuator rod being disposed within the opening;
an adjustment member rotatably disposed within the body and including a threaded inside cavity in communication with the opening, the inside cavity being threadably engaged the actuator rod;
an actuator rod opening disposed through the body and positioned adjacent the adjustment member to receive a section of the actuator rod therein to facilitate contacting the actuator rod from a position outside of the body; and
an attachment opening disposed through the body for attachment with a linkage member;
wherein the linkage member is connected with a movable member of the turbocharger assembly.
12. The actuator mechanism as recited in claim 11 wherein the rod end connector body members each include registration surface features that are positioned at identical locations to confirm alignment of the body members.
13. The actuator mechanism as recited in claim 11 wherein the rod end connector includes a flange that extends radially outwardly from the body adjacent the longitudinal end of the body having the opening, the actuator rod being disposed through a central opening through the flange.
14. The actuator mechanism as recited in claim 11 wherein the rod end connector comprises a lock nut threadably engaged with the actuator rod, and wherein the lock nut is positioned against the flange.
15. The actuator mechanism as recited in claim 11 wherein the rod end connector attachment opening further comprises a ball member movably disposed therein.
16. The actuator mechanism as recited in claim 15 wherein the rod end connector ball member is movable omnidirectionally within the opening and includes a radiused outside surface.

19. A method for attaching an actuator rod extending from an actuator to a rod end connector, the actuator being used to control a movable member of a turbocharger assembly, the method comprising the steps of:
inserting an end of the actuator rod into a body of a rod end connector and rotating a threadable member disposed within the body to threadably engage the actuator rod to achieve a connection between an attachment member of the rod end connector and a desired linkage, wherein the body includes an opening therethrough that accommodates a section of the actuator rod disposed within the body and that enables contact of the actuator rod from a position outside of the body;
placing the rod end connector within a fixture comprising at least one member that holds the rod end body in place, and a member that contacts and holds the actuator rod section extending through the opening in a fixed position relative to the body; and
tightening a lock nut against a surface of the body, the lock nut being threadably engaged with a portion of the actuator rod extending outside of the body;
wherein during the step of tightening, the actuator rod remains fixed relative to the body.
20. The method as recited in claim 19 wherein the actuator is pneumatically operated and includes a diaphragm disposed therein, and wherein the actuator rod is connected with the diaphragm.
