Described nut is made up of bearing, spacer and nut cap, and described bearing is fixed in nut, and roller is located in two bearings by stretching out in nut base apertures.
Stopping sliding door also comprises the parts such as case, door leaf, driving, operation, release mechanism.Casing component is connected with passenger car body, and driver part is fixed on case, and driver part is connected with left leading screw, drives left guide screw movement.Left and right leading screw is fixed on horizontal sliding support by support.Roll in the leading screw guide groove of left and right at roller, roller is located in nut, and nut is by taking door frame rocking arm and taking door frame and be connected, and nut passes to the power of leading screw to take door frame assembly by taking door frame rocking arm.
Take on door frame assembly roller shaft and roller are installed, in roller sliding way, slide; Long linear axis is fixed on horizontal sliding support, take door frame assembly and be connected with long linear axis by linear bearing, take door frame on long linear axis with being contained in the door leaf of taking on door frame, door leaf drives lower swing arm assembly again, slidably reciprocate along door opening fore-and-aft direction, realize the opening and closing action of door.
Laterally sliding support is contained on the support of left, center, right by linear bearing, sliding way is to be grouped into by straight part with the arc portion of certain angle, wherein the straight part of sliding way is parallel with long linear axis, close the door action fast ending phase, be contained in and take door frame assembly upper roller shaft and roller slides into sliding way curved arc part, take door frame assembly with door leaf and lower swing arm assembly, drive horizontal sliding support, on the support of left, center, right, slide along short lines axle left and right (along inside and outside direction of car door), pull work thereby realize plug.
Door lock in driver part and tripper are connected with operating means, between the inside and outside operating means of functional unit, and between operating means and door lock, realize interlock by wire rope.
Adopt the technical solution of the utility model, the leading screw of roller screw transmission and change helical pitch, transmission efficiency is high, long working life, effectively door closing force is large, and manual mode switch gate is laborsaving.
