Abstract
The utility model relates to a radial guiding device of a passenger car steering bogie, which comprises two guiding rod, a mounting seat, a guiding damper and a guiding damper seat. The middle part of the mounting seat is rotationally fixed on a side beam through a circular pin, the both ends of the mounting seat are respectively rotationally connected with one end part of the guiding rod, the other end of the guiding rod is respectively connected with an axle box which is opposite to the front and the rear wheels of the guiding rod through a bolt, the guiding damper seat is fixedly connected with the side beam, and the guiding damper seat is fixedly connected with the guiding damper seat and the mounting seat through bolts. When device passes through a curve, the applied force of a steel rail to the front wheel pair ensures the axle box on the front wheel pair to drive a guiding rod to move, to ensure the mounting seat to rotate around the circular pin, and the other guiding rod to pull the axle box on the rear wheel pair to drive the rear wheel pair to move, because the different applied forces, the rotating directions of the mounting seats on the inner side and the outer side of the steering bogie are different, the wheel pairs are prompted to tend to the radial direction on the curve, thereby the applied force of the wheel pairs to the steel rails is improved, the transverse applied force between the wheel and the rail and the abrasion are reduced, and the security of the steering bogie passing through the curve is guaranteed.
Description
Technical field
The utility model relates to a kind of passenger car bogie radial guide means that is used for, and belongs to passenger train manufacturing technology field.
Background technology
When ordinary train is travelled on bend,, make the wheel rim of wheel be close to rail, produce strong friction, even also will squeeze that root rail of outside and outwards move, can cause derailing when serious and train is toppled over owing to be subjected to very big centrifugal action.For train safe, in bend place outer rail palpus superelevation,, offset centrifugal action so that the compartment produces centripetal force, the speed of a motor vehicle is fast more, and superelevation of outer rail is just big more.In addition, train speed is big more, and the radius of curvature of bend will be big more.But it is limited that the raising of outer rail height and bend radius of curvature increase, and has just fixed when building, speed also can not be too high when train was crossed bend, and running velocity also can not fit like a glove with design value, like this, will increase the unbalanced wearing and tearing of rail at the bend place.Simultaneously, train gradually changes by transition bend (being entered the part of bend by straight way) with by the required centripetal force of stable state bend, and the adjusting of depending merely on train speed also is difficult to adapt to.Be subjected to the restriction of existing line superelevation and radius of curvature at present, train generally must slow down by bend the time, directly reduces the running velocity of the whole journey of train, and development has a negative impact to the railway transportation under the background of China railways speed raising.
Summary of the invention
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of passenger car bogie radial guide means, can during at a high speed by bend, slow down horizontal force and abrasion between wheel track at passenger vehicle.
The technical scheme that its technical matters that solves the utility model adopts is as follows: a kind of passenger car bogie radial guide means, it is characterized in that forming and comprise: two pilot bars, mount pad, the guiding damper, and guiding damper seat, the round pin rotational fixation is passed through on curb girder in described mount pad middle part, its two ends are rotationally connected with an end of pilot bar respectively, the other end of described pilot bar is respectively with preceding, the right axle box of trailing wheel passes through bolted connection, described guiding damper seat is captiveed joint with curb girder, and the guiding damper is captiveed joint with mount pad with guiding damper seat by bolt respectively.
The beneficial effects of the utility model are as follows: when vehicle passes through curve, rail makes front-wheel drive a pilot bar motion to last axle box to front-wheel to application force, thereby allow mount pad rotate around round pin, allow the right axle box of another root pilot bar pulling trailing wheel force trailing wheel again to motion, because the different application forces of interior outer rail, outside mount pad hand of rotation is inconsistent in the bogie truck, make the bogie truck front and back wheel pass through curve like this to becoming " eight " font, impel wheel on curve, being tending towards radially, thereby improve the application force of wheel and rail, can slow down horizontal force and abrasion between wheel track greatly, its abrasion loss only is about 1/10th of a common bogie truck, can prolong the service life of wheel and rail,, guarantee the safety of bogie truck by curve for train high-speed cruising on curve has been created condition.
Description of drawings
Fig. 1 is the utility model passenger car bogie radial guide means structural representation.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
As shown in Figure 1, the utility model passenger car bogie radial guide means, its composition comprises: two pilot bars 11,12, mount pad 2, guiding damper 5, and guiding damper seat 4, round pin 21 rotational fixation are passed through on curb girder 3 in mount pad 2 middle parts, its two ends respectively with pilot bar 11, an end of 12 is rotationally connected, pilot bar 11, the other end of 12 is respectively with preceding, the axle box 61 that trailing wheel is right, 62 pass through bolted connection, guiding damper seat 4 is captiveed joint with curb girder 3, and guiding damper 5 is captiveed joint with mount pad 2 with guiding damper seat 4 by bolt respectively.Guiding damper 5 plays buffer shock-absorbing.
