Further, since the steel plate 51 is made of a steel material, even though the steel plate 51 is constantly in contact with the vehicle lifting tool 200 when the entire vehicle is lifted, the steel plate made of a steel material has a certain structural strength, and thus can have a good abrasion prevention effect.
In a particular embodiment, the wear member is configured as a tab, rib or recess. The projections, the ridges, and the recesses are provided mainly to increase the contact friction force between the steel plate 51 and the vehicle lifting jig 200, and to prevent the vehicle lifting jig 200 and the vehicle lifting seat 5 from moving sideways when the vehicle lifting jig 200 lifts the entire vehicle.
It will be readily appreciated that the wear member is not limited to that set out in the above embodiments, and may be adapted accordingly to the actual requirements.
In another embodiment, as shown in fig. 1 and 5, a lift hole 52 is formed in the outer side surface of the anti-serpentine damper seat 4.

Therefore, in the application, as various improvement modes are made on the vehicle lifting seat 5 for vehicle lifting, the diversity of vehicle lifting is increased, and the vehicle lifting operation under various working conditions can be met.
In summary, since the body bolster 1 is mounted on the chassis structure of the vehicle, and needs to bear the whole vehicle body structure, the anti-rolling mounts 2 are respectively mounted at the two ends of the outer side surface of the body bolster 1, and the anti-rolling mounts 2 are connected with the anti-rolling devices (not shown in the figure) on the bogie (not shown in the figure), so that the condition that the stress occurs on one side of the body bolster 1 can be effectively avoided, the safe and stable operation of the vehicle is ensured, and meanwhile, the novel vehicle body bolster structure has good fatigue resistance and stress resistance.
In addition, by configuring the anti-roll mounting seat 2 to be an open structure, that is, by making the opening on the anti-roll mounting seat 2 face outward, it is easy to replace the screw seat 3 when the screw seat 3 is damaged, and at the same time, it is also possible to greatly facilitate the installation, maintenance and removal of the anti-roll device.
In addition, two vehicle lifting structures are arranged on the vehicle lifting seat 5, namely, a vehicle lifting hole 52 is arranged on the side surface of the snake-shaped damper seat 4, and one end of the vehicle lifting tool 200 is inserted into the vehicle lifting hole 52, so that the vehicle lifting operation can be completed; or the vehicle lifting seat 5 is arranged on the lower plane of the snake-shaped resistant damper seat 4, one end of the vehicle lifting tool 200 is in contact with the steel plate 51, and the whole vehicle is gradually lifted in the process of continuously providing upward acting force to the steel plate 51 by the vehicle lifting tool 200.
