As shown in fig. 7, welded frame 11 is equipped with hitch rotational stop 20 and Horizontal control lever rotational stop 47, with limit Hitch and semitrailer yaw motion drift angle processed avoids bogie and car body that fold back effect longitudinally occurs along train, to guarantee railway Derailment coefficients are no more than standard requirements when operating 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；It will turn 211 front of front beam of combined semitrailer 2 is placed in frame 1, by 12 side of slope towards front beam 211.

As shown in Fig. 8 step 2, bogie 1 is pushed to enter 211 lower plane of front beam, until front beam 211 stops with longitudinal Gear 45 contacts, and combined 2 front end of semitrailer is lifted in pushing course, rises connecting pin 33, passes through flexural pivot 34 and connecting box 32, the company of completion hangs, and back end beam 213 tilts down at this time.

As shown in Fig. 8 step 3, another bogie 1 is placed in 213 rear portion of back end beam of combined semitrailer 2, it will 12 side of slope of bogie 1 is towards back end beam 213.

As shown in Fig. 8 step 4, bogie 1 is pushed to enter 213 lower plane of back end beam, until back end beam 213 stops with longitudinal Gear 45 contacts, and combined 2 rear end of semitrailer is lifted in pushing course, rises connecting pin 33, passes through flexural pivot 34 and connecting box 32, the company of completion hangs.

Wherein, as shown in Fig. 8 step 3, when bogie 1 and back end beam 213 contact, contact point is on the right side of O point, to prevent from connecing The arm of force of touch is excessive, and bogie 1 is caused to rotate around O point, therefore, increases 12 lower part inclination angle of slope, makes itself and combined half When 2 lower plane of trailer contacts and bears combined 2 weight of semitrailer, 1 hitch end of bogie will not be by combined semitrailer 2 It 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. After the company of completion hangs, the control valve of the wheel shaft air suspension apparatus 25 with enhanced feature is operated, promotes vehicle wheel shaft 22 to than highway Operating 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 bogie 1, then passes through welding structure Traction coupling device 3 on frame 11 is connected with the vehicle frame 21 of combined semitrailer 2, is constituted completely by drawing coupling device 3 Railway unitrain, connection relationship between coupler and draft gear 16, bogie 1 and vehicle frame 21 and traditional lorry are entirely 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 the freedom of nodding of vehicle frame 21 Yu bogie 1 Degree, connecting pin 33 are solely subjected to shear, and do not have to bear moment of flexure.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
