Low-floor urban rail vehicle plays more and more important effect, present Low-floor urban rail vehicle in a lot of urban transportations, and its articulated structure is bodywork-type articulated structure, and bogie is traditional bogie.Continuous progress along with city rail vehicle, the requirement of city rail vehicle is more and more higher, especially for the little curve negotiation ability of city rail vehicle, accordingly, it is desirable to provide the attachment structure between a kind of new bogie and car body is to improve the little curving performance of city rail vehicle.
Utility model content
This utility model main purpose is in that to solve the problems referred to above and deficiency, it is provided that the bogie of a kind of little curving performance that can improve low-floor rail vehicle.
Another main purpose of the present utility model is in that, it is provided that a kind of low-floor rail vehicle being provided with above-mentioned bogie.
For achieving the above object, the technical solution of the utility model is:
A kind of bogie, including bolster, is provided with floating bearing between described bolster and car body, and described car body is connected by multiple first bolts are fixing with the inner ring of floating bearing, and described bolster is connected by multiple second bolts are fixing with the outer ring of floating bearing.
Further, being also equipped with car body and connect seat between the bottom and floating bearing of described car body, described car body, car body connect seat, the inner ring of floating bearing connects by the first bolt is fixing.
Further, described car body connects the upper surface of seat and has upper positioning boss protruding upward, lower surface has downwardly projecting lower positioning boss, described upper positioning boss inserts in the centre bore of car body when mounted, described lower positioning boss inserts in the inner ring of described floating bearing, and the center of described car body connection seat has passes through hole.
Further, it is connected by the 3rd bolt is fixing between described car body connection seat and car body.
Further, described first bolt is installed from car body floor.
Further, having the containing cavity of downward indent at the center of described bolster, described floating bearing is arranged in this containing cavity.
Another technical scheme of the present utility model is:
A kind of low-floor rail vehicle, is provided with above-mentioned bogie.
To sum up content, a kind of bogie described in the utility model and be provided with the low-floor rail vehicle of this bogie, floating bearing is utilized to be connected with bogie by car body, not only can realize the transmission of traction and brake force when vehicle runs better, carry vertical, transverse direction, longitudinal loading, realize big corner between car body and bogie, vehicle is made to pass through sharp radius curve, drastically increase the little curve negotiation ability of vehicle, and it is simple and compact for structure, connecting bolt can be dismounted from vehicle floor, improve and lift car and fall the operation sequence of car and environment.
Accompanying drawing explanation
Fig. 1 is this utility model LEO vehicle structure schematic diagram；
Fig. 2 is this utility model bogie structure schematic diagram.
As depicted in figs. 1 and 2, car body 1, bogie 2, bolster 3, floating bearing 4, inner ring 4a, outer ring 4b, the first bolt 5, the second bolt 6, car body connects seat 7, and upper positioning boss 8, lower positioning boss 9, by hole 10, containing cavity 11, centre bore 12.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of low-floor rail vehicle, including car body 1 and bogie 2, bogie 2 includes framework, bolster 3 etc., is provided with floating bearing 4, carries vertical, vertical and horizontal load by floating bearing 4 between bolster 3 and car body 1.
Car body 1 is connected by multiple first bolts 5 are fixing with the inner ring 4a of floating bearing 4, and bolster 3 is connected by multiple second bolts 6 are fixing with the outer ring 4b of floating bearing 4.
For the ease of processing, in the present embodiment, being also equipped with car body and connect seat 7 between the bottom of car body 1 and floating bearing 4, car body connects seat 7 simple in construction, it is easy to processing.
Car body connects and is connected by the 3rd bolt (not shown) is fixing between seat 7 and car body 1, and car body 1, car body connect seat 7, the inner ring 4a of floating bearing 4 connects again through the first bolt 5 is fixing.Car body connects the upper surface of seat 7 and has upper positioning boss 8 protruding upward, lower surface has downwardly projecting lower positioning boss 9, upper positioning boss 8 inserts in the centre bore 12 of car body 1 when mounted, lower positioning boss 9 inserts in the inner ring 4a of floating bearing 4, and car body connects the center of seat 7 to be had by hole 10.
Have the containing cavity 11 of downward indent at the center of bolster 3, floating bearing 4 is arranged in this containing cavity 11, namely can protect floating bearing 4, can improve again the bearing capacity of floating bearing 4.
When mounted, first with the 3rd bolt, car body is connected seat 7 to be assemblied together with car body 1, it is assemblied together followed by the second bolt 6 outer ring 4b by floating bearing 4 and bolster 3, finally utilizes the first bolt 5 that car body 1, car body are connected seat 7 and be connected with the inner ring 4a of floating bearing 4 from car body floor face.
When vehicle is by small curve radius bend, there is lateral shift in car body 1 and bolster 3, now, the inner ring 4a and outer ring 4b of floating bearing 4 relatively rotate, increase the transversal displacement between Ackermann steer angle car body and bogie, making the sweep that rail vehicle passes through less, curving performance is higher.And floating bearing 4 has bearing capacity by force, rotates feature flexibly, it is possible to improve motility when bogie is turned.
As it has been described above, in conjunction with the plan content given by accompanying drawing, it is possible to derive similar technical scheme.In every case it is the content without departing from technical solutions of the utility model, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the scope of technical solutions of the utility model.
