Abstract
The invention provides a hinge mechanism for low-floor rail vehicles. The hinge mechanism comprises a spherical hinge, an inner ball hinge block, a spherical shell hinge block, and a clamping sleeve; the spherical hinge is composed of an inner sphere and a spherical shell by fitting. The spherical shell hinge block is circular; the spherical shell is disposed in the spherical shell hinge block; the spherical shell and the spherical shell hinge block are in interference fit; the upper and lower ends of the inner sphere are planes; the inner sphere hinge block is U shaped; two inner walls of the U shape of the inner sphere hinge block press the planes of the inner sphere; the inner sphere and the sidewalls, corresponding to the two planes of the inner sphere, of the U shape are provided with through holes, and the clamping sleeve is disposed at the two ends of the through holes so that the inner sphere is fixedly connected with the inner sphere hinge block. The hinge mechanism has the advantages that the structure is simple, machining and mounting are facilitated, high-strength traction force and braking force of vehicles can be borne, the steering requirements of vehicles can be met, the manufacturing and assembly process is simple, mounting and maintenance are facilitated, the vehicles can stably pass small-radius curves, and the requirements of urban rail vehicles at -25 DEG C to +40 DEG C for operating environment and installation can be met.
Description
Technical field
The utility model relates to a kind of urban track traffic low floor vehicle, is specifically related to a kind of low-floor rail vehicle is coupled together and forms the linkwork of fixing marshalling.
Background technology
" low floor " is a nomenclature of light rail vehicle, refers to the rail traffic vehicles that vehicle floor identity distance is less than 40 centimetres from orbital plane.Because entrance is low, thereby do not need to arrange platform, get on or off the bus very convenient.From the market of international guideway vehicle, the sales volume of low-floor rail vehicle day by day increases, and applies also more and more extensive.According to incompletely statistics, more than 140 city of more than 20 country had low-floor rail vehicle in the world.For the ease of curve negotiating, between guideway vehicle, conventionally adopt articulator body structure.In the middle of existing articulated system, majority is upper and lower two cover oscillating bearing compositions, its complex structure, and parts machining technique and accuracy requirement are higher, and installation and maintenance inconvenience.
Summary of the invention
In order to overcome the above problems, to the object of the present invention is to provide a kind of simple in structure, movable parts self-lubricating, be convenient to installation and maintenance, realize connection between vehicle modules and the articulated mounting of load distribution.
Low-floor rail vehicle linkwork provided by the invention, comprises that endosphere coordinates ball pivot, endosphere hinged seat, spherical shell hinged seat, the gripping sleeve forming with spherical shell; Wherein spherical shell hinged seat is ring-type, and spherical shell is placed in interference fit in spherical shell hinged seat and between the two; The upper and lower two ends of endosphere are plane, and endosphere hinged seat is that U-shaped, U-shaped both sides inwall is pushed down endosphere two planes, and endosphere and the U-shaped sidewall corresponding with endosphere two planes are provided with through hole, and gripping sleeve is placed in respectively these two ends, hole endosphere is fixedly connected with endosphere hinged seat.
When use, endosphere hinged seat is fixedly connected with the car body of adjacent orbit vehicle respectively with spherical shell hinged seat, because endosphere and the spherical shell of ball pivot relatively rotate around the public centre of sphere, endosphere hinged seat and spherical shell hinged seat are fixing with it respectively again, so it can transmit tractive force and the braking force of vehicle, and the ball structure of ball pivot can freely rotate in three directions, guarantee car body turning, nod and the motion such as swing, thereby be convenient to vehicle mountain descending and turn to.
Key component in the middle of hinged is reduced to a set of spherical joint bearing by this structure, the articulated jib of connection body both sides is designed to U-shaped plug-in type, it is simple in structure, processing and easy for installation, and can guarantee to bear the high-intensity tractive force of car body and braking force and meet the requirement that car body is turned.And its fabrication technology is simple, be convenient to installation and maintenance, guarantee that vehicle, steadily by sharp radius curve, can meet the needs of 40 ℃ of city railway vehicle running environment of-25 ℃ ~ ﹢ and installation.
In order to reach better effect, low-floor rail vehicle of the present invention can also adopt following measures with linkwork:
1, described spherical shell and spherical shell hinged seat seam are provided with groove, are provided with snap ring in groove, and snap ring and spherical shell and spherical shell hinged seat tensioner are fixed.Thereby make between spherical shell and spherical shell hinged seat be fixedly connected with more firm.
2, described gripping sleeve is provided with flange, and the spherical shell hinged seat corresponding with flange is provided with groove, in the middle of gripping sleeve, is provided with through hole, by the bolt and nut in through hole, endosphere is fixedly connected with hinged seat.This kind of fixed form is simpler, and is more convenient to install, overhauls and maintenance.
3, described spherical shell inner ring is provided with PTFE knitting.Can bear so larger diametral load, also can play self-lubricating function, without charging-up lubricant oil, greatly facilitate maintenance and the maintenance of vehicle.
4, between ball pivot upper and lower two ends endosphere and spherical shell, be provided with rubber sheath.Can prevent that like this dust from entering oscillating bearing, extend bearing service life.
5, intensity bearing alloy steel in described ball pivot employing.Dynamic ductility is good like this.
6, described protecting jacket end is provided with bolted cover.
