Abstract
The invention provides a global locking device for screw drive of track vehicle door system, which is characterized by comprising a driving shaft, an end-toothed disc, an end-toothed shaft, a drive plate, a one-way bearing, a transition sleeve, a driven shaft, a sleeve, a torsional spring and a bracket. The global locking device has the advantages that: the device transmits power from a driving end to a driven end in both positive and negative directions, while the driven end only transmits power to the driving end in one direction; and thus the global locking device used in a rack vehicle door system in screw drive can realize a global locking, namely, the door can be manually moved only to the close direction at any position (neither close completion location nor close starting location) and can be opened and closed automatically in a natural state. The global locking device is simply structured and can keep a relatively high safety with a low reliability.
Description
Technical field
The present invention relates to a kind of global locking device that is applicable to screw drive of track vehicle door system, belong to the track communicating door technical field.
Background technology
The development of rail vehicle is maked rapid progress, and the functional and human oriented design of its parts has been proposed the very requirement of harshness.The locking device that is applied at present in the track vehicle door system has two kinds, and a kind of is the terminal point locking, namely after door is closed by mechanical locking; Another kind is, omnidistance locking, and namely door at an arbitrary position only can be towards the direction motion of closing the door.Two kinds of locking devices respectively have pluses and minuses, and the terminal point lock structure is simple, and safety is lower; The global locking device complex structure, safe.
Summary of the invention
What the present invention proposed is a kind of global locking device for screw drive of track vehicle door system, its purpose is intended to realize that the positive and negative transferring power of drive end is to driven end, and driven end only unidirectional delivery power is to drive end, the track vehicle door system that is used for worm drive is realized omnidistance locking.
Technical solution of the present invention: its structure comprises driving shaft, end-toothed disc, the end tooth axle, driver plate, unilateral bearing, the transition axle sleeve, driven shaft, axle sleeve, torsion spring, support, wherein torsion spring internal diameter and axle sleeve external diameter and end tooth axle external diameter interference fit, driving shaft keeps rotating synchronously by being fixedly connected with the transition axle sleeve, driven shaft and axle sleeve rotate synchronously and and driving shaft between exist rotate differential, support is installed on the permanent position, end-toothed disc is connected on the support, end-toothed disc and the engagement of end tooth axial end tooth, restriction end tooth axle rotates in a circumferential direction, driving shaft is connected with motor, driven shaft is connected with screw mandrel, and driver plate and unidirectional unilateral bearing join.
Advantage of the present invention: this device can be realized the positive and negative transferring power of drive end to driven end, and driven end only unidirectional delivery power therefore for the track vehicle door system of worm drive, can realize omnidistance locking to drive end.I.e. door at an arbitrary position (non-door-closing in-place position and close the door original position), under the manual state, door only can be towards the direction motion of closing the door; Under the auto state, door can be realized automatic opening and closing door.Simple in structure, in the low situation of reliability, still keep higher safety.
Description of drawings:
Accompanying drawing 1 is enforcement structure of the present invention (not operating emergency unlocking device) schematic diagram.
Among the figure 1 is driving shaft, the 2nd, and end-toothed disc, the 3rd, end tooth axle, the 4th, driver plate, the 5th, unilateral bearing, the 6th, transition axle sleeve, the 7th, driven shaft, the 8th, axle sleeve, the 9th, torsion spring, the 10th, bearing, the 11st, screw mandrel, the 12nd, power source.
The specific embodiment
Contrast accompanying drawing 1, its structure comprises driving shaft 1, end-toothed disc 2, end tooth axle 3, driver plate 4, unilateral bearing 5, transition axle sleeve 6, driven shaft 7, axle sleeve 8, torsion spring 9, support 10, wherein torsion spring 9 internal diameters and axle sleeve 8 external diameters and end tooth axle 3 external diameter interference fit, under condition satisfies situation, can relatively rotate between torsion spring 9 and axle sleeve 8 and the end tooth axle 3.Driving shaft 1 and transition axle sleeve 6 keep rotating synchronously by being fixedly connected with, driven shaft 7 rotate synchronously with axle sleeve 8 and and driving shaft 1 between exist rotation differential.Support 10 is installed on the permanent position, and end-toothed disc 2 is connected on the support 10, can only move vertically, and end-toothed disc 2 and the engagement of end tooth axle 3 end-tooths, restriction end tooth axle 3 rotates in a circumferential direction.Torsion spring 9 is rectangular torsionals.Driving shaft 1 is connected with power source, and driven shaft 7 is connected with screw mandrel 11.Power source is motor, and screw mandrel is the worm drive pair with certain lead angle.Driver plate 4 joins with unilateral bearing 5.。
Embodiment 1, duty (motorized motions):
At closing time: the motor input power is to driving shaft 1, driving shaft 1 turns clockwise, after the differential angle that turns over axle sleeve 8, drive axle sleeve 8 and turn clockwise by being fixedly connected with the transition axle sleeve 6 and the driven shaft 7 that keep rotating synchronously with axle sleeve 8, because torsion spring 9 is the dextrorotation torsion spring, and axle sleeve 8 direction of rotation are torsion spring loose ring direction, therefore, driving shaft 1 and axle sleeve 8, driven shaft 7 turn clockwise together, drive screw mandrel 11 rotations and realize closing the door.
When opening the door: the power source input power is to driving shaft 1, driving shaft 1 is rotated counterclockwise, exist angle differential between driving shaft 1 and axle sleeve 8 and the driven shaft 7, driving shaft 1 rotates counterclockwise first, owing to being connected by screw, transition axle sleeve 6 and driving shaft 1 keep being synchronized with the movement, therefore driving transition axle sleeve 6 rotates counterclockwise, under the effect of unilateral bearing 5, driver plate 4 also is rotated counterclockwise synchronously, thereby dial loose torsion spring 9 left ends packing tightly end tooth axle 3, then driving shaft 1, transition axle sleeve 6, driver plate 4, axle sleeve 8, unilateral bearing 5 and rectangular torsional 9 rotate to realize driving shaft 1 counterclockwise transferring power to driven shaft 7 around end tooth axle 3 together, and driven shaft 7 drive screw mandrels 11 are rotated counterclockwise to be realized opening the door.
At closing time: screw mandrel 11 turns clockwise under the drive of door, driven shaft 7 rotates synchronously with screw mandrel 11, driven shaft 7 also turns clockwise, driving driving shaft 1 and axle sleeve 8 turns clockwise, because direction of rotation is dextrorotation torsion spring 9 loose ring directions equally, driven shaft 7 turns clockwise and can with transmission of power to driving shaft 1, therefore realize manually closing the door.
When opening the door: screw mandrel 11 is wanted to be rotated counterclockwise under the drive of door, because differential on driven shaft 7 and driving shaft 1 angle, can not directly drive driving shaft 1 when therefore driven shaft 7 rotates is rotated counterclockwise, only can be rotated counterclockwise synchronously with axle sleeve 8, and this moment, axle sleeve 8 was rotated counterclockwise the direction that increases into torsion spring 9 frictional force, therefore axle sleeve 8 can't be rotated counterclockwise, thereby has reached screw mandrel 11 and driven shaft 7 can't be rotated counterclockwise the requirement of opening the door.Because the action of opening the door can be under an embargo in the optional position of door, therefore guaranteed security requirement.
