Single drive system for driving components of sliding vehicle closure member
View Patent ↗A common drive system drives multiple systems within a sliding vehicle closure member with a single drive motor. A controller selectively connects the drive motor to either a door drive assembly, a window drive assembly, or a lock module drive assembly through a selector assembly in response to actuation of a particular input. The selector assembly includes a transmission which shifts the drive motor between multiple gear trains to drive the particular drive assembly.
1. A drive system comprising:
a drive motor having an output;
a lock module drive assembly;
a window drive assembly;
a door drive assembly which drives a sliding door between a first position and a second position; and
a selector assembly selectively movable between a first position in which said output engages said lock module drive assembly such that said drive motor operates said lock module drive assembly, a second position in which said output engages said window drive assembly such that said drive motor operates said window drive assembly, and a third position in which said output engages said door drive assembly such that said drive motor operates said door drive assembly.
2. The system as recited in claim 1 , wherein said lock module drive assembly comprises a first gear train, said window drive assembly comprises a second gear train, and said door drive assembly comprises a third gear train.
3. The system as recited in claim 1 , wherein said selector assembly comprises a transmission.
4. The system as recited in claim 1 , wherein said selector assembly shifts between a first gear train which drives said lock module drive assembly, a second gear train which drives said window drive assembly and a third gear train which drives said door drive assembly.
5. The system as recited in claim 1 , further comprising a control in communication with said selector assembly to selectively move said selector assembly.
6. The system as recited in claim 1 , further comprising a control in communication with said selector assembly to selectively move said selector assembly from a first gear train to a second gear train to momentarily stop operation of said first gear train to drive said second gear train and then move said selector back to said first gear train to drive said first gear train.
7. The system as recited in claim 1 , wherein said selector assembly communicates with only one of a plurality of gear trains in each said selector assembly position.
