Abstract
The utility model relates to a radial type truss steering bogie. One corbel and two side beams are hinged with each other to form the truss, and the weight of vehicles is evenly distributed on a spring mechanism via the side beams, so that the conflict of the design of the torsional stiffness and the torsion resistant flexibility can be solved, the vehicles can be kept away from the influence of a twisted orbit, the accident of digression can be prevented and the safety performance can be enhanced. The steering bogie is provided with two lengthwise side beams and one horizontal corbel, which are hinged with each other, a linear motion actuator of the railcar is hung below the corbel, and the front and the back ends of the lengthwise side beams are respectively fixed and connected on an axle box body of a wheel pair. Like the integral proposal, when the wheel pair runs to a curve with an abrupt bend angle, the lengthwise side beam can twist according to the fluctuation of the orbit by taking the corbel as a fulcrum, so as to have the random protective function on the truss.
Description
Technical field
The utility model relates to a kind of bogie truck that is used for guideway vehicle, adopts the radial type framework specifically, belongs to mechanical manufacturing field.
Background technology
The existing bogie truck that is applied to the guideway vehicle of railroad train, subway and light rail transit generally adopts the rigid frame structure.
Owing to be subjected to the influence and the restriction of the track circuit of vehicle operating, when wheel when driving to the anxious curve of bent angle, the outside of rigid frame, can bear bigger torsional interaction near the right position of wheel.The weight of guideway vehicle fully drops on the framework, and the suppleness that the framework rigidity of existing bogie truck is bigger and anti-twist is less, therefore is subjected to the adverse effect of track distortion, is easy to occur derailment accident.
On the structure design of existing bogie truck, be difficult to thorough solution for torsion stiffness and the mutual contradiction of antitorque flexibility, it is unreasonable that it is also that according to reason framework structure designs.
The utility model content
The purpose of this utility model is to provide a kind of radial type frame work steering frame, to address the above problem and defective.1 sleeper beam and 2 curb girders that employing is hinged are formed framework, make that to be distributed evenly at one be on the spring installation through curb girder for the weight of vehicle, and then solve torsion stiffness and the conflict in design of antitorque flexibility, avoid vehicle to be subjected to the influence of track distortion, the generation that prevents derailment accident and raising safety performance.
For realizing above-mentioned design goal, described radial type frame work steering frame has:
1 horizontal sleeper beam and 2 vertical curb girders of being hinged, the linear electric motors of guideway vehicle are hung below described sleeper beam, and vertically the front and back ends of curb girder is fixedly connected on respectively on the right journal box body of wheel.
As above-mentioned overall plan, when wheel when driving to the anxious curve of bent angle, vertically curb girder can be that fulcrum is distorted according to the fluctuating of track and with the sleeper beam, thereby framework is played the ccasual protective effect.
And the distortion of this class can occur in the front and back ends of 2 vertical curb girders, promptly with the point of connection of journal box body on, no matter how the right medial and lateral of front and rear wheel are subjected to the influence of track distortion.
For improving the antitorque flexibility ability of framework, described horizontal sleeper beam is provided with a pair of hinged seat, and 2 vertical curb girders run through respectively and are connected on the hinged seat.
For improve linear electric motors by bogie truck to taking turns right longitudinal traction effect, the both sides of described horizontal sleeper beam front and back ends are connected with 4 longitudinal tie respectively, the other end of longitudinal tie is connected the end of forward and backward journal box body.
The impulsive force that forms for bogie truck and car body when reducing vehicle operating, the influence of avoiding being subjected to the track distortion, the front and back ends of described vertical curb girder is that the rubber metal pad of spring installation connects forward and backward journal box body by one respectively.
Further refinement scheme is to be provided with to bilateral symmetry a pair of air bellow above described horizontal sleeper beam.
As above content, the advantage of articulated frame work steering frame is, sleeper beam that employing is hinged and curb girder are formed framework, make that to be distributed evenly at one be on the spring installation through curb girder for the weight of vehicle, torsion stiffness and the conflict in design of antitorque flexibility have thoroughly been solved, vehicle can not be subjected to the influence of track distortion, can prevent the generation of derailment accident effectively, and safety performance is higher.
Description of drawings
Now with explanation the utility model is done further explanation in conjunction with the following drawings.
Fig. 1 is the structural representation of described truck frame;
As shown in Figure 1, sleeper beam 1, curb girder 2, hinged seat 3 is taken turns to 4 journal box body 5, longitudinal tie 6, rubber metal pad 7 and air bellow 8.
The specific embodiment
Embodiment 1, and as shown in Figure 1, the guideway vehicle of using the radial type frame work steering frame has front and rear wheel to 4, is provided with journal box body 5 in the inboard of taking turns 4.
Guideway vehicle utilizes linear electric motors and experiences the power that plate produces, and forms tractive force longitudinally.
Bogie truck has a horizontal strut, and framework has 1 horizontal sleeper beam 1 and the 2 vertical curb girders 2 that are hinged.
Described horizontal sleeper beam 1 is provided with 3,2 vertical curb girders 2 of a pair of hinged seat to be run through respectively and is connected on the hinged seat 3.
Wherein, the linear electric motors of guideway vehicle are hung below described sleeper beam 1.
Vertically the front and back ends of curb girder 2 is fixedly connected on wheel respectively on 4 the journal box body 5.
The both sides of the front and back ends of horizontal sleeper beam 1 are connected with 4 longitudinal tie 6 respectively, and the other end of longitudinal tie 6 is connected the end of forward and backward journal box body 5.
Vertically the front and back ends of curb girder 2 is the forward and backward journal box body 5 of rubber metal pad 7 connections of spring installation by one respectively.
Above horizontal sleeper beam 1, be provided with to bilateral symmetry a pair of air bellow 8.
