Abstract
The invention relates to a vehicle end damping device for a rail vehicle, which belongs to the field of rail vehicles and solves a problem that the taking comfort of a train is reduced due to impact generated by lateral oscillation or head shaking of the train. According to the invention, the vehicle end damping device for the rail vehicle is mounted between a front vehicle body and a rear vehicle body and comprises two symmetrically arranged damping units, wherein each damping unit comprises a friction beam, at least two sets of buffering mechanisms, a mounting beam and a steel wire rope; the buffering mechanisms are arranged between each friction beam and each mounting beam in parallel; the friction beam of one damping unit is in contact with the friction beam of the other damping unit; the mounting beams are respectively mounted on the front vehicle body and the rear vehicle body; and the two ends of the steel wire rope are respectively connected with the mounting beam and the friction beam in a stressed state. The invention, is advantaged in that the vehicle end damping device for a rail vehicle is convenient to detach, the lateral oscillation reducing effect between the vehicle bodies is enhanced and the taking comfort is improved.
Description
Technical field
The present invention relates to Draft gear, particularly relate to a kind of Draft gear used for rail vehicle.
Background technology
Guideway vehicle is often saved compartment and is connected by hitch between compartment, and hitch plays buffer action for front and back the asynchronous of compartment in vehicle operation.But, when guideway vehicle is by the less bend of radius, or the whole lateral vibration in compartment, front and back, or often save compartment self swing yaw motion time, will produce great impact to compartment, make a big impact to passenger inside the vehicle, the ride quality of guideway vehicle will significantly reduce.
Summary of the invention
Main purpose of the present invention is to solve the problem and not enough, provides the Draft gear used for rail vehicle be a kind ofly convenient to dismantle, improved lateral vibration absorbing effect between car body, improve ride quality.
The present invention is achieved in that a kind of Draft gear used for rail vehicle, is arranged between the car body of front and back, comprises: symmetrically arranged two damping units, and each damping unit comprises friction beam, at least two cover buffer gear, mounting rail and steel ropes; Described buffer gear is disposed in parallel between friction beam and mounting rail; The friction beam of a damping unit contacts with the friction beam of another damping unit, and mounting rail is arranged on the car body of front and back respectively; The connection of tension state is carried out with mounting rail, the beam that rubs respectively in steel rope two ends.
In the middle of the advancing of train, when the inconsistency of adjacent compartment, particularly when train carries out turning or occur lateral vibration or yaw motion, two friction beams laterally will produce dislocation, longitudinally produce phase mutual friction and collision, the distortion that the different pressures be subject to according to it occurs in various degree by some cover shock absorbers, two the asynchronous generation angles of beam because of front and back car that rub, farthest reach damping, buffering and correction effect, make train operation steady, have obvious effect to the raising of train ride quality.
In order to reach better effect, Draft gear used for rail vehicle of the present invention, can adopt following measures:
1. buffer gear described in comprises guide guide rod structure, spring, platen, and wherein spring housing is outside guide guide rod structure, and guide rod is connected with friction beam, and guide is connected with mounting rail.When buffer gear is subject to external force, guide rod slides relative to guide, thus spring compresses, and plays buffer action.
2. guide described in is without at the bottom of cylinder, and position corresponding with guide rod on described mounting rail is provided with the circular hole that guide rod can be made to pass through.Can increase guide rod stroke like this thus increase buffering regulated quantity, or guide guide rod structure required under the state reaching same adjustment amount is the shortest.
3. guide described in is connected with friction beam by bearing pin.Thus guide rod can carry out small rotation, increase lateral adjustments degree.
4. the external diameter of guide described in, close to the internal diameter of spring, arranges platen between described mounting rail and spring.Position-limiting action can be played to spring.
5. be provided with flange bottom guide described in, be fixed by pin between this flange with mounting rail and be connected.
6. each damping unit described in comprises 2 buffer gears, and symmetrical being arranged on is rubbed between beam and mounting rail.

In figure, each piece number illustrates:
1-rubs beam; 2-mounting rail; 3-spring; 4-guide; 5-guide rod; 6-platen; 7-steel rope; 8-bearing pin; 9-car body; 10-sells.
Detailed description of the invention
Below in conjunction with accompanying drawing, 1 couple of the present invention is described in further detail.
As shown in Figure 1, Draft gear used for rail vehicle of the present invention, comprise: symmetrically arranged two damping units, each damping unit comprises the friction beam 1 and mounting rail 2 that be arranged in parallel, two cover guides 4 and guide rod 5 structure is set up in parallel between mounting rail 2 and friction beam 1, guide 4 is poured on guide rod 5, flange is provided with bottom guide 4, flange is provided with pin-and-hole, guide 4 is fixedly connected with mounting rail by pin 10, guide rod 5 is connected by bearing pin 8 with friction beam 1, and guide rod 5 slides thus the distance between friction beam 1 and mounting rail 2 is changed thereupon in guide 4.The position that mounting rail 2 is corresponding with guide rod 5 has through hole, at the bottom of guide 4 is not provided with tin, thus guide rod 5 can eject guide 4 when sliding in guide 4 reaches in the hole of mounting rail 2 always, increase the distance of stretch out and draw back of guide 4, increase the distance adjustment degree before friction beam 1 and mounting rail 2.Outside guide 4, be provided with the spring 3 of internal diameter slightly larger than guide 4 external diameter, be provided with platen 6 between spring 3 and friction beam 1, thus position-limiting action can be played to spring 3.Connect with steel rope 7 between mounting rail 2 and friction beam 1, the length of steel rope 7 is less than the length of spring 3, thus makes steel rope be in tension state.
Draft gear used for rail vehicle of the present invention is arranged between the car body of front and back, and the mounting rail 2 in above-mentioned two damping units is fixedly connected with front and back car body respectively, and two friction beams 1 contact.
In the middle of the advancing of train, when the inconsistency of adjacent compartment, particularly when train carries out turning or occur lateral vibration or yaw motion, two friction beams laterally will produce dislocation, longitudinally produce phase mutual friction and collision, the distortion that the different pressures be subject to according to it occurs in various degree by some cover shock absorbers, two the asynchronous generation angles of beam because of front and back car that rub, farthest reach damping, buffering and correction effect, make train operation steady, have obvious effect to the raising of train ride quality.
As mentioned above, plan content given in conjunction with the accompanying drawings and embodiments, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
