ELECTROMECHANICAL STRUT WITH LATERAL SUPPORT FEATURE

摘要

An electromechanical strut for moving a closure member between open and closed positions relative to a vehicle body includes a housing having an inner surface bounding a cavity extending along a central axis between opposite first and second ends. A power screw is disposed in the cavity in operable communication with a motor, with a gear assembly operably connecting the motor to the power screw. An extensible member has an outer cover tube received in the housing cavity and a drive mechanism for converting rotary motion of the power screw into linear motion of the extensible member. An annular gap extends between the inner surface of the housing and an outer surface of the outer cover tube. An annular bushing is disposed within the annular gap to minimize laterally play between the housing and the outer cover tube.

1. An electromechanical strut for moving a closure member between an open position and a closed position relative to a motor vehicle body, the electromechanical strut comprising:
a housing operably connected to one of the closure member and motor vehicle body, said housing having a tubular wall with an inner surface bounding a cavity extending along a central axis between opposite first and second ends; a motor operably fixed to said housing adjacent said first end; a power screw disposed in said cavity; a motor gear-assembly operably connecting said motor to said power screw for operable rotation of said power screw; an extensible member operably connected to the other of the pivotal closure member and the motor vehicle body, said extensible member having an outer cover tube at least partially received in said cavity through said second end of said housing and having a drive mechanism for converting rotary motion of said power screw into linear motion of said extensible member to move said extensible member between a retracted position and an extended position relative to said housing; an annular gap defined between said inner surface of said housing and an outer surface of said outer cover tube; and an annular bushing disposed within said annular gap, said annular bushing maintaining said gap and minimizing lateral play between said housing and said outer cover tube.
