US Patent:

6367344, Apr 9, 2002

Filed:

Nov 21, 2000

Appl. No.:

09/716367

Inventors:

Carl Randall Vogt - Raleigh NC
Richard K. Rader - Laguna Hills CA
James David Warren - Clayton NC

Assignee:

BorgWarner Inc. - Troy MI

International Classification:

B60K 4106

US Classification:

74335, 7447312

Abstract:

An integrated shift motor and electronic controller reduces weight and provides improved performance. The shift control motor includes an output shaft having a first sensor wheel and adjacent sensor which provide signals regarding the rotation and direction of rotation of the motor. The motor drives a gear train having an output member which is coupled to and rotates a shift rail. A sensing wheel is disposed on the output member and adjacent sensors provide signals regarding the angular position of the output member. The sensors drive a microcontroller which in turn drives the shift control motor. Preferably, the sensors, the drive motor, the gear train and the microcontroller are all disposed in a housing. The rotating shift rail includes a pair of spaced-apart followers which engage a cam member which bi-directionally positions a shift fork associated with a multiple position clutch or shift collar.

International Classification:

F16H 5900

US Classification:

743375

Abstract:

Shift control assembly for a power transmission device includes an electric drive motor and gear train having an output which is coupled to and bi-directionally rotates a shift rail. The shift rail includes a pair of spaced-apart cam followers. Freely rotatably receiving the shift rail and disposed thereon between the cam followers is a shift fork assembly. The shift fork assembly includes a body having a pair of spaced-apart helical cam surfaces engaged by the cam followers and a fork engaging a shift clutch collar. As the shift rail rotates bi-directionally, the shift fork assembly and clutch collar bi-directionally translate. A circular plate is disposed for rotation with the shift rail and includes an array of apertures. A plurality of sensors are disposed in adjacent, sensing relationship to the circular plate. As the circular plate and shift rail rotate, the sensors generate unique combinations of signals corresponding to a plurality of specific angular positions of the shift rail and translational positions of the shift fork.
