摘要： A modular drive assembly for a sliding door, comprising: a guide track having a hinge slidably received therein; a pair of pulleys disposed on either end of the guide track; a pair of cables each having an end that is secured to the hinge and the other end is secured to a cable drum of a motor drive unit mounted to the guide track, the motor drive unit being configured to rotate the cable drum, wherein the cable drum is also capable of freely rotating within the motor drive unit when the motor drive unit is not rotating the cable drum, wherein rotation of the cable drum causes the hinge to move in the guide track as one of the cables wraps onto the cable drum while the other one of the cables wraps off of the cable drum.

摘要翻译： 一种用于滑动门的模块化驱动组件，包括：导轨，其具有可滑动地容纳在其中的铰链; 一对滑轮，设置在导轨的任一端; 一对电缆各自具有固定到铰链的端部，另一端固定到安装到导轨的电动机驱动单元的电缆卷筒上，马达驱动单元被配置为旋转电缆卷筒，其中电缆 当马达驱动单元不旋转电缆滚筒时，滚筒还能够在电机驱动单元内自由旋转，其中当电缆卷绕到电缆滚筒上时，电缆滚筒的旋转导致铰链在导轨中移动，同时 另一条电缆从电缆卷筒上松开。
