The invention relates to a railway wagon bogie and side frame cross bar mechanism connection method. The railway wagon bogie and side frame cross bar mechanism connection method is characterized in that the relative motion between two side frames within the horizontal plane is eliminated by a five-bar mechanism, so that a stable structure is achieved. The five-bar mechanism comprises three connecting bars and two bars formed by the two side frames, the two side frames are connected with both ends of the three connecting bars, so that the five-bar mechanism is formed in the horizontal plane, and the relative motion between the two side frames within the horizontal plane is eliminated by the five-bar mechanism assembly. Since the railway wagon bogie and side frame cross bar mechanism connection method adopts the five-bar mechanism side frame control principle and the five-bar mechanism side frame control mechanism on the basis of a conventional three-major part type bogie, the defects of poor performance stability and structural stability existing in currently used four-cross bar connection bogies are overcome, the structural fatigue reliability of vehicles and the critical speed of vehicle running are increased effectively, the dynamic acting force between wheels and rails is decreased, and thereby the purpose of increasing the running speed and running quality of wagons and reducing operation and maintenance costs is achieved.
Description
Technical field
The present invention relates to a kind of parts coupling method and device of goods train vehicle, be specifically related to a kind of railway goods train bogie and side frame cross rod mechanism coupling method and device, be mainly used in fast, heavy duty goods train prevents the relative motion that produces between side frames in horizontal surface, belongs to railway truck manufacturing technology field.
background technology:
Railway goods train bogie refers to a kind of running gear of railway truck.Divide by structural shape at present, mainly contain cast steel three-piece bogie and framework type bogie truck two kinds.Wherein, simply, all carry the advantages such as performance is good because research railway goods train bogie has structure, be able to widely apply on railway truck.This bogie truck to, the composition such as bearing, adapter, side bearing, foundation brake rigging, plays the effect of supporting body, guiding and braking primarily of side frame, bolster, shock attenuation unit, wheel.But, in tradition three-major-items roller bearing adapter stabilizer bar, the connection of side frame and bolster only realizes by shock attenuation unit, thus easily produces the relative motion in horizontal surface between its side frames, the serpentine locomotion that aggravation wheel is right, thus affect safety and the riding quality of vehicle operating.
In order to overcome this shortcoming, a large amount of production is improved traditional Bogie Designs with the improved type three-piece bogie used at present, increases coupling mechanism, suppress the relative motion of side frames in horizontal surface between side frames.The structural shape that current coupling mechanism generally adopts is: between side frames, increase by two cross connection bars, connected by elastic panel nodes with side frames, side frames is made to form a four-bar linkage in horizontal surface together with two connecting rods, enhance the contact between side frames, good effect is achieved to the safety in operation and riding quality improving bogie truck.The cross link coupling method of current extensive application mainly contains two kinds:
1) interfixed by connecting device between two cross link;
2) between two cross link, nothing is contacted directly.
But being found by the operation of a period of time, there are some problems in current coupling method.Subject matter and producing cause as follows:
The subject matter that the first coupling method exists and producing cause are: this structure is used by a large amount of entrucking in current railway truck, in utilization process, find that a large amount of cross link produces structural fatigue crackle.And once endurance crack cause pipe link rupture after, bogie truck run snakelike critical speed can sharply decline, bring high risks to the safe in operation of vehicle.
Because four-bar linkage itself exists a freedom of motion, do not considering under the prerequisite that other external constraint affects, one of them side frame can produce relative rotation to another one side frame, makes the rectangular configuration under initial condition become trapezium structure, thus the homophase causing wheel right is snakelike.By increase between two cross link connecting device fixing after, side frames forms a stable structure together with two cross link, from kinematic angle, relatively rotating between side frames can be eliminated by this mechanism, makes bogie truck have good dynamic performance.But increase anchor fitting between two connecting rods after, change the strained condition of two connecting rods, side frame longitudinally (track alignment) moves the additional bending moment produced mutually, can be delivered on crossbar, thus cause rod member or anchor fitting fatigue failure.
The subject matter that the second side frame coupling method exists is: this coupling method, contacts directly between two connecting rods without any, and connecting rod itself only bears the pressure effect that side frame transmits, and is thus easy to realize good structural fatigue reliability.But as mentioned above, but theoretically, there is a freedom of motion in four-bar linkage itself.After being subject to extraneous excitation, between side frame, mutual rotation will be produced, thus affect the positive capability of bogie truck, cause the snakelike critical speed of bogie truck to decline.Therefore, be necessary to adopt a kind of better side frame coupling method to solve the relative position control problem of truck side frame; Structure itself answers reasonable stress simultaneously, has excellent fatigue property.
Do not find that there is the patent literature constructed with the present invention by patent retrieval, to have the patent of certain relation to mainly contain following with the present invention:
1, patent No. CN201420336888.1 and the patent No. are announced for CN201410283231.8, name is called " a kind of railway goods train bogie and wherein cross-braced device ", by being fixed device to reach the rotation eliminated between side frames at two crossbar overlapping parts, thus stroke rock-steady structure.But obviously, produce when mutually rotating between side frame, this position will produce very large additional bending moment, thus causes the fatigue failure of crossbar.
2, patent No. CN200910017141.3 announces, name is called " a kind of crossed rod mechanism for rail wagon bogie ", the motion eliminated between side frames is reached by a six-bar mechanism, but when the power produced between side frames is transmitted by two parallel bars, still additional bending moment can be produced, affect its strength at repeated alternation, the more complicated and structure seems.
3, the patent No. is CN200920029942.7, and the patent of invention that name is called " a kind of Novel crossing bar type railway freight car bogie ", which discloses a kind of Novel crossing bar type railway freight car bogie, comprises side frame, crossbar device and axle box rubber packing.Inside side frame, column is provided with the cross bar mount pad of crossbar device, and mount pad and side frame integrated are cast out, and welding manner also can be adopted to be connected with side frame column; Crossbar device is made up of two parallel cross bar, two crossbars and eight articulation pieces, two crossbars are connected with two cross bars by four articulation pieces, whole crossbar device is connected with the cross bar mount pad of four in side frames by four articulation pieces, therefore this patent set forth the crossed rod type railway goods train bogie being still a kind of six bar structures, still there is the problem described in a upper patent.
So although these patents above-mentioned all relate to the crossbar device of railway goods train bogie, it is also proposed the improvement that some are structural, but all fundamentally do not change existing crossbar device, all still there is the deficiency of foregoing 2 aspects, therefore still need to be improved further.
