Abstract
The utility model relates to an elastic hinging device in a hinging mechanism, which is used for connecting a plurality of low-floor railway vehicles together for forming the elastic marshalling in an urban railway system. The elastic hinging device serves as an auxiliary connecting mechanism between low-floor vehicles, restricts the side rolling or the nodding movement between the vehicle bodies, and meets the requirement that a vehicle can pass through a minor-radius horizontal curve. The elastic hinging device has the advantages that the hinge connection by elastic balls has larger radial rigidity and smaller torsional rigidity, the nodding freedom degree between vehicles is released, the requirement that a vehicle can pass through a minor-radius horizontal curve can be met, and the side rolling or the nodding movement between the vehicle bodies is restricted; and the elastic hinging device can be used with an oil damper to ensure the liner-motion stability of vehicles. The elastic hinging device is characterized by simple structure, safe and reliable operation, and convenient overhaul, replacement and repair, and effectively solves the problem that a plurality of low-floor railway vehicles in the urban railway system need to be connected for marshalling.
Description
Technical field the utility model relates to the hinged elasticity articulated mounting of using of a kind of urban low-floor rail vehicle.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 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 existing space under the floor, develop the hinged elasticity articulated mounting of using of a kind of low-floor rail vehicle, when transmitting longitudinal traction power and braking force, satisfy the requirement of city small curve radius and steep gradient.
The summary of the invention the purpose of this utility model is: for the urban low-floor rail traffic vehicles provides a kind of elasticity 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 hinged structure with the elasticity articulated mounting of this urban low-floor rail vehicle is: center pin and rigidity gib head are fixed as one, elastic joint is secondary to be fixed as one with the elasticity gib head, the external diameter of ball pivot joint pair matches with the endoporus of elastic joint pair, and its internal diameter matches with the external diameter of center pin.Center pin is a straight pin.The elastic joint pair is a spherical rubber joint pair.Ball pivot joint pair is a spherical rigidity joint pair.
Elasticity articulated mounting in this linkwork of the present utility model for elastic ball is hinged, is used for low floor vehicle and connects hang last hinged, when can satisfy by the requirement of minor radius level curve, and the motion of sidewindering or nod between the constraint vehicle.
The utility model urban low-floor rail vehicle is hinged with elasticity articulated mounting advantage to be: for elastic ball is hinged, radial rigidity is bigger, and torsional stiffness is less, discharge the degree of freedom of shaking the head between car body, can satisfy the requirement of vehicle by the minor radius level curve, retrain the motion of sidewindering or nod between carbody simultaneously, itself and oil-pressure damper are used, and guarantee vehicle straight-line motion stationarity.This elasticity 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 utility model elasticity articulated mounting structural representation.
1 the utility model is described in further detail in conjunction with the accompanying drawings for the specific embodiment: the elasticity articulated mounting is made up of rigidity gib head 1, center pin 2, elasticity gib head 3, elastic joint pair 4, ball pivot joint secondary 5.Center pin 2 in the elasticity articulated mounting is a straight pin, is fixed as one with rigidity gib head 1; Elastic joint secondary 4 is the spherical rubber joint, is fixed as one with elasticity gib head 3, and its radial rigidity and torsional stiffness satisfy the requirement that vehicle is nodded and sidewindered design angle; Ball pivot joint secondary 5 is spherical rigidity joint, and its external diameter matches with the endoporus of elastic joint pair 4, and internal diameter matches with the external diameter of center pin 2.
