Abstract
The utility model relates to a locking device for vehicle door systems, which is characterized in that an input shaft 9 is connected with a motor, an output shaft 2 is connected with a screw rod and a plurality of wedge blocks 10 are uniformly distributed between the input shaft 9 and the output shaft 2 one by one. The input shaft 9 and the output shaft 2 are arranged in and outer sleeve 1, the wedge block 10 is pebble-shaped, the output shaft 2 is provided with holes, a spring 11 is arranged in the hole and is abutted with the wedge block 10 and the spring 11 is arranged between two wedge blocks 10. The utility model has the advantages that a wedge block type one-way overrunning clutch with a pusher dog has good manufacturability and easy fabrication, an inner ring adopts a working surface with a concave circular arc slot so as to reduce contact stress and lighten abrasion of contact parts and the utility model is profitable for increasing the carrying capacity of the wedge blocks and extending service life. Meanwhile, the utility model has the advantages of large curvature radius of contact points, multiple wedge blocks, high capability, compact structure, small size, reliable self hold and easy reverse disengagement.
Description
Technical field
The utility model relates to a kind of locking device that is used on the train-door system, belong to train-door system
Technical field.
Background technology
The existing general complex structure of door lock assembly, part is more, and needs use power source in addition, and reliability is not high, a phenomenon of Guan Bushang takes place often, not opening.Do not satisfy supporting with it door system requirement in reliability, practicality, maintainability and safety.As a kind of roller band pusher dog mono-directional overrun clutch structure, this structure relies on the frictional force on the contact surface fully, yet the size of the contact surface angle of wedge directly influences the reliability of locking device.In fact reliable in order to guarantee self-locking, often select less inclination angle for use, the consequence that causes thus is oppositely to throw off, particularly under the situation that power of motor is restricted, this problem is outstanding especially.Roller band pusher dog mono-directional overrun clutch generally can only be selected 3～4 structures that roller is such for use owing to be subjected to the restriction of structure, and therefore, the stress that makes every roller bear surpasses YIELD STRENGTH.
Summary of the invention
The object of the invention is the defective at above-mentioned existence, the locking device that a kind of train-door system uses is proposed, it promptly is a kind of Wedge-type band pusher dog mono-directional overrun clutch structure, solved the problem that roller band pusher dog mono-directional overrun clutch exists, the reliability of the locking device of train-door system is improved.Satisfy the requirement of modern vehicle door system the reliability height, safe, maintainability good, long service life.Technical solution of the present invention: its structure is that power shaft links to each other with motor, and output shaft links to each other with screw mandrel, and several voussoirs are distributed between power shaft and output shaft in turn, and power shaft and output shaft are contained in the overcoat, and described voussoir is the cobble shape.Establish spring in the hole, spring withstands voussoir, establishes spring between two voussoirs.
Advantage of the present invention: its good manufacturability of Wedge-type band pusher dog mono-directional overrun clutch structure, easy to manufacture, interior ring adopts the work plane of concave arc groove, can reduce contact stress, alleviate the wearing and tearing of contact site, help improving the supporting capacity of voussoir, increase the service life.Simultaneously, the contact point radius of curvature is big, and voussoir is many, the supporting capacity height, and compact conformation, appearance and size is little, and self-locking is reliable, oppositely throws off easily.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention,
Accompanying drawing 2 is the A-A cut-away views among Fig. 1.
Among the figure 1 is overcoat, the 2nd, output shaft, the 3rd, and axial elasticity ring washer, the 4th, the hole is with elastic scheibe, the 5th, deep groove ball bearing, the 6th, spacer ring, 7, the 8th, ring washer, the 9th, power shaft, the 10th, voussoir, the 11st, spring has several.
The specific embodiment
The contrast accompanying drawing, its structure is that power shaft 9 links to each other with motor, output shaft 2 links to each other with screw mandrel, several voussoirs 10 are distributed on 2 of power shaft 9 and output shafts in turn, spring 11 acts on voussoir, and power shaft 9 is contained in the overcoat 1 with output shaft 2, and described voussoir 10 is the cobble shape.Establish spring 11 in the hole, spring 11 withstands voussoir 10, establishes spring 11 10 of two voussoirs.Several voussoirs 10 that are the cobble shape are distributed between output shaft 2 and the power shaft 9 in turn, the voussoir 10 that is the cobble shape will import/and active force on the shaft one by one is delivered to and exports/go on the axle, finish the transmission work of the torsional forces on input/shaft, when output shaft 2 rotates by counter clockwise direction, spring 11 acts on voussoir, voussoir and overcoat 1 are kept in touch, and obtain certain initial frictional force, voussoir 10 withstands overcoat 1, make power shaft 9 left alone without help commentaries on classics, be in auto state, when output shaft 2 rotates in the direction of the clock, voussoir (10) is delivered to power on the power shaft 9 one by one, and power shaft 8 and output shaft 2 are rotated synchronously.During work, motor drives the output shaft forward and backward by power shaft, rotates thereby drive screw mandrel, realizes the opening and closing of car door.
