Abstract
A free articulated device for the articulation of urban low-floor railway vehicles is characterized in that the articulated device is in Z-shaped connecting rod structure; two ends thereof are fixed on a vehicle body and are in herical hinge with two ends of a side-rolling pull rod in the middle. The free articulated device is an auxiliary connecting mechanism between the low-floor vehicles, restrains the side-rolling movement between vehicle bodies, and simultaneously adapts to the demand that the vehicles pass through a minor-radius horizontal curve and a minor-radius vertical curve. The free articulated device has the advantages of being in the Z-shaped connecting rod structure, releasing the degree of freedom of shaking and nodding between the vehicle bodies, meeting the requirement that the vehicles pass through a minor-radius horizontal curve and a minor-radius vertical curve, simultaneously restraining the side-rolling movement between the vehicle bodies, being matched with an oil damper for use, and guaranteeing the stability of vehicle liner movement. The free articulated device has simple structure, safe and reliable running, and convenient overhauling, replacement and maintenance, and effectively solves the problems that a plurality of low-floor vehicles are connected and grouped in urban railway traffic.
Description
Technical field the utility model relates to a kind of free articulated mounting in a kind of urban low-floor rail vehicle usefulness linkwork.Belong to the rail traffic vehicles technical field.
Background technology is present, increase along with the urban passenger flow amount, the vehicle more piece connects extension to be become inevitable, and urban rail transit vehicles develops to the low floor direction, do not had traditional hitch space, urban inner track circuit radius of curve is little in addition, and the ramp is steep and many, be badly in need of a kind of low-floor rail vehicle and connect the on-hook structure, linkwork can satisfy above-mentioned requirements fully.Tradition highland plate coupling of vehicles is realized by hitch under the floor, because coupler slack is bigger, have a strong impact on riding quality, though adopted tight lock coupler afterwards, but be difficult to satisfy the requirement of urban inner small curve radius, and the low floor vehicle floor is very near apart from rail level, has not had traditional hitch space.Make full use of roof top existing space, develop the free articulated mounting of a kind of low-floor rail vehicle, when satisfying city small curve radius and steep gradient requirement, retrain the motion of sidewindering between vehicle.
The summary of the invention the purpose of this utility model is: for the urban low-floor rail traffic vehicles provides a kind of free articulated mounting in the linkwork.Make it can either satisfy coupling of vehicles and operation needs, simple in structure again, application safety is reliable, it is convenient to open and inspect repair and replacement, effectively solves urban track traffic more piece low floor vehicle and connects the problem of hanging marshalling.
The structure of the free articulated mounting of the hinged usefulness of this urban low-floor rail vehicle is: the two ends of sidewindering pull bar are respectively equipped with the secondary and elastic joint pair in ball pivot joint.Sidewinder that pull bar is made up of two band drawheads of reverse threads and centre link cover; The secondary external diameter in ball pivot joint matches with the endoporus of left lever head, and internal diameter matches with the external diameter of rigidity gib head connecting pin, and rigidity gib head connecting pin is fastened on the rigidity gib head; The secondary external diameter of elastic joint matches with the endoporus of right drawhead, and internal diameter matches with the external diameter of elasticity gib head connecting pin, and elasticity gib head connecting pin is fastened on the elasticity gib head.Ball pivot joint pair is a spherical rigidity joint pair.The elastic joint pair is a spherical rubber joint pair.
Free articulated mounting in this linkwork of the present utility model, it is " Z " font bar linkage structure, two ends are fixed on the car body, are respectively the rigidity typed ball bearing pair with medial side rolling drawing bar two ends and are connected with the elasticity typed ball bearing pair.What be used for that low floor vehicle connect to hang is last hinged, when can satisfy the requirement by minor radius level curve and vertical curve, retrains the motion of sidewindering between vehicle.
The utility model urban low-floor rail vehicle with the advantage of the free articulated mounting in the linkwork is: be " Z " font bar linkage structure, two ends are fixed on the car body, being respectively the rigidity typed ball bearing pair with medial side rolling drawing bar two ends is connected with the elasticity typed ball bearing pair, discharge and to shake the head between car body and nod degree of freedom, can satisfy the requirement of vehicle by minor radius level curve and vertical curve, retrain the motion of sidewindering between carbody simultaneously, be used, guarantee vehicle straight-line motion stationarity with oil-pressure damper.This free articulated mounting is simple in structure, application safety reliable, open and inspect repair and replacement conveniently, effectively solves urban track traffic more piece low floor vehicle and connects the problem of hanging marshalling.
Description of drawings
Fig. 1 is the free articulated mounting front view of the utility model.Fig. 2 is the birds-eye view of Fig. 1.
1 the utility model is described in further detail in conjunction with the accompanying drawings for the specific embodiment: free articulated mounting by rigidity gib head 1, rigidity gib head connecting pin 2, ball pivot joint pair 3, sidewinder pull bar 6, elastic joint pair 8, elasticity gib head connecting pin 9, elasticity gib head 10 and form.Wherein sidewindering pull bar 6 is made up of dextrorotation drawhead 4, drag link sleeve 5, left-handed drawhead 7.The pull bar 6 that sidewinders in the free articulated mounting is made up of the drawhead 4,7 and the centre link cover 5 of two band reverse threads, according to position relation between two connection car bodies, adjusts distance between two drawheads 4,7 by centre link cover 5, is locked by double nuts.Elastic joint secondary 8 is the spherical rubber joint, and its external diameter matches with the endoporus of drawhead 7, and internal diameter matches with the external diameter of elasticity gib head connecting pin 9.Ball pivot joint secondary 3 is spherical rigidity joint.Its external diameter matches with drawhead 4 endoporus, and internal diameter matches with rigidity gib head connecting pin 2 external diameters.
