    • A sliding door in a van is mounted on tracks for sliding movement between open and closed positions. At the closed position a weather strip is compressed and a door latch is latched. A cable is attached to the door and routed through the vehicle body via pulleys so that pulling the first cable end opens the door and pulling the second cable end closes the door. A motorized drive mechanism includes first and second reels mounted concentrically and having the cable ends wrapped respectively about the reels in opposite directions. A motor drives in one direction rotating the first reel to open the door and is reversible to rotate the second reel to close the door. Each of the reels has a large diameter portion for winding the cable to provide relatively high speed and low force door movement over the greatest portion of travel and a small diameter portion for winding the cable to provide relatively low speed and high force movement of the door during the lesser portion of travel of the door closest to the closed position. The reels have cable set grooves to receive the cable and a spiral ramp groove to connect the large and small diameter portions. A tension retaining spring acts between the two reels to always maintain the cable under tension.
    • 货车中的滑动门安装在轨道上,用于在打开和关闭位置之间滑动。 在关闭位置,气压条被压缩并且锁闩被锁定。 电缆连接到门并通过滑轮穿过车身,以便拉动第一电缆端部打开门并拉动第二电缆端部关闭门。 电动驱动机构包括同心安装的第一和第二卷轴,并且电缆端部分别围绕相反方向的卷轴缠绕。 电动机沿一个方向驱动旋转第一卷轴以打开门,并且可逆地旋转第二卷轴以关闭门。 每个卷轴具有大直径部分,用于缠绕电缆以在行进的最大部分上提供相对高速度和低力的门运动,以及用于卷绕电缆的小直径部分以提供门的相对低速和高的力运动 在最靠近关闭位置的门的较小部分行程中。 卷轴具有用于接收电缆的电缆固定槽和用于连接大直径部分和小直径部分的螺旋斜坡槽。 张力保持弹簧作用在两个卷轴之间,以始终保持电缆处于张紧状态。
