Description
Technical field
The present invention relates to the transmission mechanism of vehicle doorn, the driver of more particularly to a kind of rail vehicle or tramcar door
Structure.
Background technology
Existing vehicle doorn mainly has two kinds of transmission mechanisms.
The first：Single open pull door for tubular synchronous linear motors, the secondary of primary, linear motor including linear motor,
The reading of square aluminium section bar, the sliding block of line slideway, the guide rail of line slideway, mounting bracket, mounting bracket, the scale of grating scale, grating scale
Upper margin, door-plate, mounting bracket and T-shaped guide rail；The both ends that the secondary 2 of linear motor passes through 6 and 7 side's of being fixed on aluminium section bar 3 of mounting bracket
On, 1 top of primary of linear motor is fixed on the sliding block 4 of line slideway, 5 side's of being fixed on aluminium section bar 3 of guide rail of line slideway
Lower part, on the side of 8 side's of being fixed on aluminium section bar 3 of scale of grating scale, the reading 9 of grating scale is fixed on the sliding block of line slideway
On 4 side；Door-plate 10 is fixed on by mounting bracket 11 in the primary of linear motor, and door-plate lower part is inserted on T-shaped guide rail 12.Directly
After the primary 2 of line motor is powered, transverse-electromagnetic thrust, straight line are generated between the primary 2 of linear motor and the primary 1 of linear motor
Electric motor primary 1 will do transverse movement, so as to directly door-plate 10 be driven to do bilateral reciprocation, realize switch gate action.
Second：The door opening and closing system of linear motor driving, door leaf fix door strap, servo-drive are installed in door head plate
Controller and rope wheel component, door head plate install linear electric motor primary fixed seat, and linear electric motor primary is installed in the fixed seat and is led
Rail, guide rail are slidably matched sliding block, and sliding block is fixedly connected with linear motor secondary fixed seat, and linear motor is installed in the fixed seat
Grade, linear motor secondary are fixedly connected with the rope of rope wheel component；Linear motor secondary fixed seat installs the reading of feedback device
Head；Servo drive controller couples with linear motor and feedback device.
The first above-mentioned transmission mechanism is since lead screw transmission mechanism is complicated, feed screw nut's processing difficulties, number of parts
It is various, be not easy to safeguard, it is of high cost the problems such as；Single open pull door for tubular synchronous linear motors then can not achieve both direction movement,
The problems such as existing simultaneously the secondary directly carrying of linear motor, influencing movement, while can not also realize that the plug of door pulls and make, therefore nothing
Method is applied to sliding plug door system.
Above-mentioned second of transmission mechanism is because linear motor transmission mechanism is using motor drive rope sheave, that is, wire rope gearing progress
The translational motion of two door leafs is realized in linkage, and steel wire rope load is very big, the problems such as so as to cause rope stretch unstable, and
It can not achieve and be also not suitable for being applied to city rail door system.
In conclusion existing vehicle door transmission system can not achieve stopping sliding door action, and stability is poor, service life,
All it is difficult to meet city rail, the requirement on tramcar door.
The content of the invention
The technical problems to be solved by the invention are to provide in view of the above shortcomings of the prior art for city rail trolley
, the linear motor transmission mechanism of tramcar door, can realize stopping sliding door act, meet city rail, tramcar
Requirement on door.
Technical solution is used by the present invention solves above-mentioned technical problem：
For city railway vehicle, the linear motor transmission mechanism of tramcar door, including fixed frame, main connector, from
Connector, line slideway, linear motor, cross slide way, Y guiders, slideway, master takes door frame, pair takes door frame, fulcrum bearing, same
Step band directive wheel, belt；Each one fulcrum bearing of support in two end of fixed frame, installs Y guiders in each fulcrum bearing, two
Cross slide way is installed between Y guiders；Linear motor is mounted on the one side of fixed frame, and the mover of linear motor passes through main connection
Part is connected on the sliding block of line slideway, and line slideway is supported by fixed frame, and main connector is also connected with synchronous belt one side, and with
Master takes door frame and is connected；Two side of fixed frame is each to fix a synchronous belt directive wheel, and two synchronous belt directive wheels pass through synchronous band connection；
Secondary connector is fixed on the opposite side of synchronous belt, and secondary connector also takes door frame with pair and is connected；Two slideways are transversely mounted on fixation
On frame, each installation of slide track is by the straightway among extroversion and segmental arc track；Master takes door frame and pair takes door frame and is sleeved on horizontal lead
On rail, master takes door frame and pair is taken and idler wheel is set on door frame, and idler wheel is placed in slideway along the track motion of slideway, so that master takes door
Frame and pair, which are taken door frame and moved along straightway and segmental arc, to be opened from centre to two sides or by two lateral closed centers.
Preferably, above-mentioned major-minor connector takes door frame with major-minor by linkage respectively and is connected, and hinge one end is provided with length
Hole so in connector and is taken and is capable of providing plane or space bidimensional degree of freedom between door frame.
Preferably, swelling device is set on above-mentioned synchronous belt.
Compared with prior art, the advantage of the invention is that：By Y guiders, slideway and linear motor master is driven to take
Door frame, pair take movement of the door frame on slideway, can realize the X of door to the compound motion with Y-direction, therefore can be applied to city
The stopping sliding door of rail, tramcar.It is complicated that existing screw rod transmission structure is also overcomed simultaneously, and feed screw nut's difficulty of processing is big, replaces
The problems such as difficulty, bumpy motion, overcomes existing single open pull door for tubular synchronous linear motors and can not achieve both direction movement
The problem of, it also solves when linear motor transmission mechanism drives rope sheave to be linked using motor and is deposited due to two door leaf motions
Steel wire rope linkage it is unstable, life requirements can not be met the defects of.
Due also to be driven using linear motor, therefore its speed is fast, operate steadily and rate curve is adjustable, electric efficiency
It is high, simple in structure, performance is stable, failure rate is low.
