TRANSMISSION FOR MOTORIZED TRACK SYSTEM |
摘要 |
A track system ( 18 ) of the type used to adjust the position a supported element such as vehicular seat ( 12 ) includes a pair of base rails ( 20 ) that slidably interact with a respective pair of driven rails ( 22 ). A transverse rail ( 24 ) is attached to each of the driven rails ( 22 ) so that the driven rails ( 22 ) slide together as a unit. A motor ( 34 ) is supported on the transverse rail ( 24 ) and includes a pair of drive shafts ( 36 ) emanating from either end. The drive shafts ( 36 ) carry on their distal ends' respective worm gears ( 38 ) which are contained within a transmission assembly ( 26 ). The worm gears ( 38 ) mesh with external teeth on respective drive nuts ( 54 ) which interact with a lead screw ( 28 ) that can be oriented to either remain stationary relative to the base rails ( 20 ) or can be rotatably fixed within the driven rails ( 22 ). The drive nut ( 54 ) is prevented from causing objectionable noise and premature wear in operation by the inclusion of one or two compressible washers ( 66 ).
