Description
Technical field
The invention belongs to railway freight-car technical fields, more particularly to a kind of semitrailer highway railway combined transport double duty truck.
Background technique
Highway railway combined transport mainly includes container highway railway combined transport and semitrailer highway railway combined transport, is the one of the following railway freight development
Main trend, and piggyback and two kinds of combined lorry are developed in semitrailer highway railway combined transport.Combined lorry be by
Lorry body is cancelled, and directly even hangs semitrailer up with bogie, reduces vehicle self weight, is conducive to improve transport warp
Ji benefit.
(CN106394681A) discloses a kind of road rail vehicle, including Highway Container half in existing application for a patent for invention
Trailer, a traction sleeper device, two traction sleeper devices, traditional three piece truck etc., are wherein still adopted between traction sleeper device and bogie
It is carried with cartridge, and coupler and draft gear is mounted on traction sleeper device one end, in order to keep balancing, the other end has hung bulky match
Pouring weight increases additional weight.Sub- hook and female hook are set on Highway Container semitrailer, are connected respectively with traction sleeper device, therefore
Two different traction sleeper devices are needed, interchangeability is reduced, sub- unciform process increases invalid vehicle commander for semi-trailer frame, turns to
Increased traction sleeper device between frame and car body increases the complexity of stress, such as under traction and compression condition, due to primary and secondary hook
With the height difference of coupler centre line, traction sleeper device will bear additional moment, reduce the reliability and maintainability of system.
With carrying out in a deep going way for highway railway combined transport, in addition to Container Transport, the semitrailers such as various cargos such as cold chain, express delivery are all needed
It realizes highway railway combined transport, needs to develop that a kind of structure is reliable, versatility and interchangeability are good, even hangs efficiently semi-trailer frame and iron
Road EEF bogie had not only met railway operation requirement, but also met highway Drop and pull transport requirement.And according to Drop and pull transport standard, plate half
Beam section height is not greater than 90mm in trailer towing part, is not able to satisfy the strength and stiffness requirement of railway operating condition longitudinal force,
Therefore, semitrailer must use gooseneck structure, and semitrailer is caused to there is front and back height difference.The direct result of front and back height difference is rail-road two
It is tilted forward and back, is such as hinged using column between semitrailer and bogie, longitudinal force will be with after even being hung with bogie with semitrailer
Horizontal plane is in a certain angle, and vertical component can cause wheel to increment of load and off-load, influences vehicle operational safety, must take measures to disappear
Except the vertical component.
Though still falling within railway freight-car scope, it is still desirable to meet railway in addition, combined lorry belongs to extraordinary lorry
Lorry and bogie operation nod, shake the head, roll freedom, inhibit bogie hunting, otherwise the railway freight-car cannot
The safety requirements for meeting normal running speed.

As shown in fig. 7, welded frame 11 is equipped with hitch rotational stop 20 and Horizontal control lever rotational stop 47, with limitation
Hitch and semitrailer yaw motion drift angle avoid bogie and car body that fold back effect longitudinally occurs along train, to guarantee railway work
Derailment coefficients are no more than standard requirements when condition Train compresses.
The forming process of highway railway combined transport double duty truck is further described below in conjunction with attached drawing 8.
As shown in Fig. 8 step 1, combined semitrailer 2 is placed in orbit centre, plane is concordant with ground on track, public
The dual-purpose semitrailer 2 of iron is put on ground level by support device 24, and vehicle wheel shaft 22 and 21 relative altitude of vehicle frame are in A；By goods
Vehicle bogie 1 is placed in 211 front of front beam of combined semitrailer 2, by 12 side of slope towards front beam 211.
As shown in Fig. 8 step 2, roller bearing adapter stabilizer bar 1 is pushed to enter 211 lower plane of front beam, until front beam 211 and longitudinal direction
Backstop 45 contacts, and combined 2 front end of semitrailer is lifted in pushing course, rises connecting pin 33, passes through flexural pivot 34 and connection
Case 32, the company of completion hang, and back end beam 213 tilts down at this time.
As shown in Fig. 8 step 3, another roller bearing adapter stabilizer bar 1 is placed in 213 rear portion of back end beam of combined semitrailer 2,
By 12 side of slope of roller bearing adapter stabilizer bar 1 towards back end beam 213.
As shown in Fig. 8 step 4, roller bearing adapter stabilizer bar 1 is pushed to enter 213 lower plane of back end beam, until back end beam 213 and longitudinal direction
Backstop 45 contacts, and combined 2 rear end of semitrailer is lifted in pushing course, rises connecting pin 33, passes through flexural pivot 34 and connection
Case 32, the company of completion hang.
Wherein, as shown in Fig. 8 step 3, when roller bearing adapter stabilizer bar 1 and back end beam 213 contact, contact point is anti-on the right side of O point
Only the arm of force of contact force is excessive, and roller bearing adapter stabilizer bar 1 is caused to rotate around O point, therefore, increases 12 lower part inclination angle of slope, makes itself and public affairs
When dual-purpose 2 lower plane of semitrailer of iron contacts and bears combined 2 weight of semitrailer, 1 hitch end of roller bearing adapter stabilizer bar will not be public
The dual-purpose semitrailer 2 of iron presses to tilt.
It is combined during the vehicle frame 21 of combined semitrailer 2 slides onto bogie slope 12 as shown in Fig. 8 step 4
The wheel shaft air suspension apparatus 25 of semitrailer 2 loses load and elongates, and vehicle wheel shaft 22 is kept and ground face contact, is in B.It is complete
After even hanging, the control valve of the wheel shaft air suspension apparatus 25 with enhanced feature is operated, promotes vehicle wheel shaft 22 to than highway work
Condition A C higher, and vehicle wheel shaft 22 is supported in railway operation, it is made to keep the safe distance with rail level.
As shown in Fig. 8 step 4, coupler and draft gear 16 is arranged on the welded frame 11 of roller bearing adapter stabilizer bar 1, then passes through weldering
The traction coupling device 3 connect on framework 11 is connected with the vehicle frame 21 of combined semitrailer 2, is made up of traction coupling device 3
Complete railway unitrain, the connection relationship and traditional lorry between coupler and draft gear 16, roller bearing adapter stabilizer bar 1 and vehicle frame 21 are complete
It is complete different.
As shown in Fig. 8 step 4, after the company of completion hangs, vehicle frame 21 and ground are in certain inclination angle, public since even hanging point is flexural pivot
The vehicle frame 21 of the dual-purpose semitrailer 2 of iron becomes two power bars, makes the direction of longitudinal force always along even hanging point line, thus keep horizontal,
Improve because the inclination of vehicle frame 21 generates negative effect of the vertical component to wheel weight；Release nodding for vehicle frame 21 and roller bearing adapter stabilizer bar 1
Freedom degree, connecting pin 33 are solely subjected to shear, and do not have to bear moment of flexure.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
