    • 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).
    • 用于调节诸如车辆座椅(12)的支撑元件的位置的类型的轨道系统(18)包括可滑动地与相应的一对从动轨道(22)相互作用的一对基座轨道(20)。 横向轨道(24)被附接到每个从动轨道(22),使得从动轨道(22)作为一个单元一起滑动。 电动机(34)被支撑在横向轨道(24)上并且包括从一端发出的一对驱动轴(36)。 驱动轴(36)承载其远端各自的蜗轮(38),蜗轮(38)包含在变速器组件(26)内。 蜗轮(38)与相应的驱动螺母(54)上的外齿相啮合,该螺母与导螺杆(28)相互作用,引导螺杆(28)可相对于基座导轨(20)保持静止,或者可旋转地固定在驱动 导轨(22)。 通过包含一个或两个可压缩垫圈(66),防止驱动螺母(54)在操作中引起令人不快的噪音和过早磨损。
