Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 1 to 4, the utility model relates to a kind of asynchronous transmission device for rail vehicle sliding plug door system, comprise motor 1, input end gear train 2, screw mandrel 3, nut 4, inner spline housing 5, external splines cover 6, output gear train 7, shift fork push rod 8, shift fork 9, roller 10, line slideway 11, unlock driving lever 12, described motor 1 and screw mandrel 3 are arranged on asynchronous transmission device casing, described motor 1 is connected with screw mandrel 3 by input end gear system 2, described nut 4 forms worm drive pair with screw mandrel 3, described nut 4 is the plastic nut of band self-lubricating function, can realize exempting from lubrication for a long time, described nut 4 lateral ends is groove, shift fork translation can be driven, outside described nut 4, the other end is external splines, spline pair is formed with inner spline housing 5, described inner spline housing 5 overlaps 6 with external splines and forms another spline pair, flat key groove is provided with inside and outside external splines cover 6, inner side is connected with subordinate screw mandrel by flat key, outside is connected with gear by flat key, nut 4 rotate through two-stage spline pair and flat key passes to subordinate's screw mandrel or output gear, described shift fork 9 is connected to by installing plate on the slide block of line slideway 11, guiding is realized by slide block, described roller 10 is arranged on slide block through installing plate equally.Described shift fork 9 has installed a shift fork push rod 8 along translation direction, unblock driving lever 12 installed by the casing of described shift fork push rod 8 front end, described unblock driving lever 12 can pull lower rotation at wire rope, and in the latched condition, the flange unlocking driving lever 12 can promote the translation of shift fork push rod.
The course of work of the asynchronous transmission device for rail vehicle sliding plug door system of the present utility model is as follows:
In the translation stage of door closing procedure, the translational degree of freedom of roller 10 is limited, thus the translational degree of freedom of shift fork 9 and nut 4 is limited simultaneously, now nut 4 can only rotate with screw mandrel 3, rotating through of nut 4 is overlapped the 6 two-stage spline pairs formed passed to subordinate's screw mandrel by the external splines of nut 4 itself, inner spline housing 5, external splines, realizes door leaf translation.
Action phase is drawn at the plug of door closing procedure, the translational degree of freedom of roller 10 is released, thus the translational degree of freedom of shift fork 9 and nut 4 is released, under the effect of feed screw nut pair, nut 4 rotates while translation, and the now rotation of nut 4 still passes to subordinate's screw mandrel by two-stage spline pair, realizes plug and pulls work, the translation of nut 4 then passes to roller 10 by shift fork 9, drives locking mechanism to realize locking by roller 10.
Action phase is drawn at the plug of door opening process, the translational degree of freedom of roller 10 is released, the translational degree of freedom of shift fork 9 and nut 4 is released, under the effect of feed screw nut pair, nut 4 rotates while translation to contrary direction of closing the door, the now rotation of nut 4 still passes to subordinate's screw mandrel by two-stage spline pair, and the translation of nut 4 then passes to roller 10 by shift fork 9, drives locking mechanism to unlock by roller 10.
The translation stage is arrived at door opening process, the translational degree of freedom of roller 10 is limited again, now nut 4 can only rotate with screw mandrel 3, rotating through of nut 4 is overlapped the 6 two-stage spline pairs formed passed to subordinate's screw mandrel by the external splines of nut 4 itself, inner spline housing 5, external splines, realizes door leaf translation.
Under emergency release operating mode, rope traction unlocks driving lever and rotates 12, and the flange unlocking driving lever 12 promotes shift fork push rod 8 to unlocking direction translation, the translation of shift fork push rod 8 drives roller 10 translation together, roller 10 drives locking mechanism, after locked position is crossed by mechanism, realizes unlocking.
