The utility model technical scheme as follows:
The transmission mechanism of ball-screw stopping sliding door adopts ball screw assembly,, and leading screw is fixed on support, and ball coordinates with the guide groove of leading screw, and ball rolls in the guide groove of leading screw, and ball is located in nut, and nut is connected with door leaf by taking door frame.
In the technical program, be provided with left leading screw and right leading screw, the helical pitch of described leading screw seamlessly transits, and plays the effect of switch gate stable action, buffering.
Left leading screw is arranged on on the left socle of bearing and the medium-height trestle with bearing, and right leading screw is arranged on on the medium-height trestle of bearing and the right support with bearing.
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.Ball rolls in the leading screw guide groove of left and right, and ball 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, roller slides in sliding way; 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, along door opening fore-and-aft direction, slidably reciprocate, 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, along about short lines axle, (along car door inside and outside direction) slides, thereby realize plug, pulls work.
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, by wire rope, realize interlock.
Adopt the technical solution of the utility model, ball-screw-transmission, owing to being to utilize ball moving, so staring torque is minimum, there will not be the such creeping phenomenon of sliding motion, can guarantee to realize accurate micro-feeding, and transmission efficiency is high, and effectively door closing force is large; Switch gate motion is more steady.Ball-screw stopping sliding door of the present utility model reaches below 1/3 than driving moment with the lead screw parafacies of available technology adopting, reaches the required power of same motion result for using 1/3 of ball-screw pair, has improved significantly transmission efficiency.
