The invention is also characterized in that:

the center of the two-axle bogie at the end of the auxiliary vehicle close to the main vehicle is provided with a longitudinal sliding groove, a stop block is arranged in the longitudinal sliding groove, and the stop block is in clearance fit with the longitudinal sliding groove, so that the two-axle bogie arranged at the position can move transversely relative to the vehicle body.

The cross section of the stop block is H-shaped, and the stop block is arranged in the longitudinal sliding groove and limited by the upper center plate and the lower center plate.

The clearance range between the stop block and the longitudinal sliding groove is 20-50 mm.

The invention adopts another technical proposal that the connection method of four railway wagons is carried out according to the following steps:

step 1, sequentially connecting a truck , a truck II, a truck III and a truck IV in series through hinges;

step 2: mounting two-axle bogie

The two-axle bogie with the main bogie and the auxiliary bogie is installed separately, and includes inserting the longitudinal sliding slot in the center of the two-axle bogie near the main bogie into the stopping block, blocking the stopping block on the lower center plate of the bogie, clamping the upper center plate of the bogie to the lower center plate of the bogie at , and connecting the other bogies without longitudinal sliding slot to the bogie via the clamping of the upper center plate to the lower center plate.

The invention has the beneficial effects that:

according to the four-truck linkage type four-truck bogie, the four-truck linkage type four-; the four-vehicle linkage truck has the characteristics of heavy load, strong transportation capacity, light dead weight, low maintenance cost and the like. The device is suitable for modern railway transportation, especially for special coal transportation lines, and plays a great role in reducing railway transportation pressure.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

kinds of four-section railway wagons, as shown in fig. 1 and fig. 2, kinds of four-section railway wagons comprise a wagon 1, a wagon two 2, a wagon three 3 and a wagon four 4 which are sequentially connected in series, wherein the wagon 1, the wagon two 2, the wagon three 3 and the wagon four 4 are supported by two-shaft bogie 5 hubs, namely, the lower hubs of the two-shaft bogies are matched with the wagon upper hubs, the wagon 1, the wagon two 2, the wagon three 3 and the wagon four 4 can only rotate and cannot move transversely and longitudinally, the wagon two 2 and the wagon four 4 are main trucks, the wagon 1 and the wagon three wagon 3 are auxiliary trucks, the two-shaft bogie adjacent to the main truck end can move transversely relative to the wagon body, the wagon 1, the wagon two 2, the wagon three 3 and the wagon four 4 are connected through hinges, a longitudinal chute 6 is arranged at the center of the two-shaft bogie adjacent to the main truck end, a stop block 7 is arranged in the longitudinal chute 6, a stop block 7 is conveniently installed at the position of the longitudinal chute 6, and a stop block 7 is arranged in the longitudinal chute 6, and a transverse chute 7 is 20-6 mm.

The specific installation process is as follows:

step 1, sequentially connecting a truck 1, a truck II 2, a truck III 3 and a truck IV 4 in series through hinges;

step 2: mounting two-axle bogie

The two-axle bogie of the main car and the auxiliary car are respectively installed, a longitudinal sliding groove 6 arranged at the center of the two-axle bogie of the auxiliary car close to the end of the main car is inserted into a stop block 7, the stop block 7 is prevented from being arranged on a lower center plate of the bogie, an upper center plate of a car body and the lower center plate of the bogie are clamped at , and the rest bogies without the longitudinal sliding grooves 6 are connected with the car body in a mode that the upper center plate is clamped with the lower center plate.

As shown in fig. 3, when the second wagon 2 and the fourth wagon 4 have entered the curve, and the wagon 1 and the wagon three 3 have also entered the curve, the position of the second wagon 2 is determined by the bogie of the wagon 1 adjacent to the end of the second wagon 2, and the bogie of the wagon three 3 adjacent to the end of the second wagon 2, and the connecting center thereof extends outside the center line of the curve, and at this time, an inward lateral offset is inevitably generated with respect to the center line of the body of the second wagon 2, and the longitudinal sliding groove 6 is provided at the stopper 7 according to the present invention, so that the lateral offset can be smoothly realized.

As shown in fig. 4, when the truck four 4 is still on the curve, the truck 1, the truck two 2 and the truck three 3 are already on the straight line, and at this time, the bogie on the truck three 3 near the truck four 4 end inevitably generates the lateral deviation towards the outside of the curve, and similarly, the longitudinal sliding groove 6 arranged on the bogie of the invention can realize the free lateral deviation of the truck three 3 near the truck four 4 end.

Therefore, the four-truck linkage mode is designed, the bogies are respectively arranged at the two ends of the non-knuckle truck, the eight bogies of the truck can be ensured to safely pass through curves and turnouts, and the stable operation in a straight line is ensured; the four-vehicle linkage truck has the characteristics of heavy load, strong transportation capacity, light dead weight, low maintenance cost and the like. The device is suitable for modern railway transportation, especially for special coal transportation lines, and plays a great role in reducing railway transportation pressure.
