The traditional automatic translation door driving device mainly comprises two types, wherein one type is driven by a screw rod motor, and the other type is driven by a belt gear. When the first type of screw rod motor works continuously and reciprocally, the first type of screw rod motor generates heat seriously, the friction loss is large, the precision is reduced, a belt gear in the other type of driving device is a quick-wear part, and the belt transmission depends on the friction force as the driving force, so that the corresponding energy loss cannot be avoided. Meanwhile, the anti-pinch function cannot be achieved only by the two driving devices, if the anti-pinch purpose is achieved, an anti-pinch system needs to be additionally added, and the cost of the sliding door is further increased. Traditional translation door relies on the rolling pulley that is located a body top or bottom to undertake the weight of whole body at the during operation, and the pulley slides in the slide rail simultaneously, plays the guide effect. The positive pressure that the pulley received mainly comes from the gravity of the door body, and this has just caused to have frictional loss between pulley and the door body, and then has restricted the opening speed of the door body, has also influenced the life of hanging wheel and hanger rail simultaneously, and long-term use still can lead to the noise increase, problem such as cost of maintenance height.
