The direct result of the front-rear height difference is that the road-railway dual-purpose semitrailer is inclined back and forth after being connected with the bogie, if a column hinge is adopted between the semitrailer and the bogie, the longitudinal force must form a certain included angle with the horizontal plane, the vertical component force can cause the increase and the decrease of the load of the wheel set, the running safety of the vehicle is affected, and measures are needed to be taken to eliminate the vertical component force.

As shown in fig. 8, step 3, another truck 1 is placed behind the rear end beam 213 of the highway-railway semitrailer 2 with the side of the slope 12 of the truck 1 facing the rear end beam 213.
As shown in step 4 of fig. 8, the truck bogie 1 is pushed into the lower plane of the rear end beam 213 until the rear end beam 213 contacts with the longitudinal stopper 45, and the rear end of the highway and railway semitrailer 2 is lifted during the pushing process, and the connecting pin 33 is lifted, and passes through the spherical hinge 34 and the connecting box 32, thereby completing the hitch.
As shown in step 3 of fig. 8, when the truck bogie 1 contacts with the rear end beam 213, the contact point is on the right side of the O point, so as to prevent the excessive moment arm of the contact force, and cause the truck bogie 1 to rotate around the O point, therefore, the inclination angle of the lower portion of the slope 12 is increased, so that the coupler end of the truck bogie 1 cannot be tilted by the truck semi-trailer 2 when the lower surface of the truck bogie contacts with the lower surface of the truck semi-trailer 2 and bears the weight of the truck semi-trailer 2.
As shown in fig. 8, step 4, in the process of sliding the frame 21 of the road-rail dual-purpose semitrailer 2 on the bogie slope 12, the wheel axle air suspension device 25 of the road-rail dual-purpose semitrailer 2 loses load and stretches, and the wheel axle 22 of the vehicle keeps contact with the ground and is in the position B.
