The transmission assembly comprises a central gear 14 and two driven gears 15 meshed with the central gear, a driving rod 17 is arranged on a wheel shaft of the central gear 14, one end, far away from the central gear, of the driving rod 17 is hinged with the telescopic end of the pushing oil cylinder 4, and the central gear 14 is driven to rotate through the telescopic action of the pushing oil cylinder 4; the wheel shafts of the two driven gears 15 are respectively provided with a swing rod 18, one end of each swing rod 18, which is far away from the driven gear 15, is hinged with the auxiliary car leaning plate 2, and the two swing rods 18 are controlled to drive the auxiliary car leaning plate 2 to be close to or far away from the central line of the railway through the rotation of the two driven gears 15. The car leaning device also comprises a bracket 5 connected to the main car leaning plate 1, the pushing oil cylinder 4 is arranged on the bracket 5, and a hinge point at the fixed end of the pushing oil cylinder 4 is connected with the bracket 5; the sun gear 14 and the two driven gears 15 are both mounted on the carrier 5.
Based on the above technical solution, it should be noted that, since the driving of the pushing cylinder 4 is transmitted through the central gear 14 and the driving rod 17, the central gear can rotate clockwise and counterclockwise within a certain angle range along with the stretching of the pushing cylinder 4, so as to drive the two driven gears 15 and the two swing rods 18 to drive the auxiliary car backing plate 2 to move within a preset range.
Further, the two driven gears 15 are respectively arranged on the upper side and the lower side of the central gear 14, the two swing rods 18 are respectively hinged on the upper side and the lower side of the auxiliary plate 2, and the two swing rods 18 are arranged in parallel. The two swing rods 18 are connected to the upper side and the lower side of the auxiliary car leaning plate 2, so that the auxiliary car leaning plate 2 is guaranteed to be stably driven to move, instability of unilateral driving is avoided, double stress points of the auxiliary car leaning plate 2 lean against the car are enabled to lean against the car, and safety factors of the car leaning are increased. The two swing rods 18 are arranged in parallel, so that the swing directions and angles of the two swing rods 18 are consistent, and the plane where the auxiliary car backing plate 2 is located is always consistent with the main car backing plate 1.

Based on the technical scheme, it needs to be explained that the structure and the appearance of the open wagon type and the container type are different greatly. Especially the container type, the structure of which is composed of two separable parts, namely a container body 8 and a container trailer 9. When the trailer leans against the trailer, the container body 8 needs to be leaned against firstly, and then the container trailer 9 needs to be leaned against. The auxiliary car leaning plate 2 is a car leaning device which is particularly increased for adapting to a container car body, and mainly has the function of increasing the car leaning area when the car is leaned against an open car; when the container is tightly leaned against, the container supporting device is pressed. When the automobile seat backrest works, the main backrest plate 1 is used as a support and acts together with the main backrest plate 1. The car leaning device is mainly composed of a main car leaning plate 1, an auxiliary car leaning plate 2, a supporting swing rod and a main car leaning oil cylinder 3. The main backing board 1 is pushed by the oil cylinder to move forwards, and simultaneously drives the auxiliary backing board to move forwards. When the bicycle is closed, the main bicycle leaning plate 1 and the auxiliary bicycle leaning plate 2 are connected together by the connecting bolt group 6 to form a whole bicycle leaning plate, and the requirement of bicycle leaning area is met. When the main car-leaning plate and the auxiliary car-leaning plate are close to the container, the main car-leaning plate 1 and the auxiliary car-leaning plate 2 are close to each other respectively, the main car-leaning plate 1 is close to the container body 8, and then the auxiliary car-leaning plate 2 is close to the container supporting vehicle 9. The auxiliary car backing plate device mainly comprises six main components, namely a bracket 5, an auxiliary car backing plate 2, a double-swing-rod device, a gear transmission device, a pushing oil cylinder 4 and a connecting bolt group 5. The bracket 5 serves to connect the auxiliary back plate device and the main back plate device together so that the auxiliary back plate device can move together with the main back plate device. The auxiliary car leaning plate 2 is used for increasing the leaning area when the car leans against the open car; and when the container is tightly leaned, the bearing support cart of the container is tightly leaned. The double swing rods have the function that the auxiliary car leaning plate 2 can swing back and forth under the drive of the gear pair and the pushing oil cylinder 4 so as to adapt to the leaning requirements of open cars and containers. The gear transmission device is used for transmitting driving force and tightening force for the swing rod device, and the gear pair with the second gear pair can provide double-vehicle tightening force for the auxiliary vehicle-leaning plate. The pushing oil cylinder 4 is used for providing driving force for the whole vehicle leaning plate device and transmitting the driving force to the auxiliary vehicle leaning plate 2 through the gear pair and the double oscillating bars. The set of connecting bolts 6 serve to connect the main and auxiliary back plates together when the truck is closed. The main car leaning oil cylinder 3 moves in a telescopic mode to drive the main car leaning plate 1, the bracket 5 and the pushing oil cylinder 4 to move synchronously, and the pushing oil cylinder 4 moves in a telescopic mode to drive the auxiliary car leaning plate 2 to move obliquely along the driving direction of the swing rod 18.
Furthermore, the two main car-leaning cylinders 3 are distributed on the upper side and the lower side of the main car-leaning plate 1, and the two main car-leaning cylinders 3 provide power for the movement of the main car-leaning plate 1 together. The hinge point of the telescopic end of the main car-leaning oil cylinder 3 is connected with the main car-leaning plate 1, and the hinge point of the fixed end of the main car-leaning oil cylinder 3 is connected with the rotor 10.
Further, the main car leaning plate 1 is rotatably connected with one end of a supporting swing rod 11 through a hinge point, the other end of the supporting swing rod 11 is rotatably connected with a swing rod support 12 through a hinge point, and the swing rod support 12 is fixed on the rotor 10. And a stop block 13 is arranged between the main car leaning plate 1 and the support swing rod 11 and is used for limiting the swing of the main car leaning plate 1.
The original position of the car leaning device is shown in figures 4-5, the tight position of the car leaning device is shown in figures 6-7, when the open car leans against the car, the oil cylinder 4 is pushed to drive the driven gear 15, so that the swing rod 18 pushes the auxiliary car leaning plate 2 to be flush with the main car leaning plate 1 and connected through the connecting bolt group 6, and the car leaning area is increased. When the container leans against the car, the auxiliary car leaning plate 2 and the main car leaning plate 1 are connected through the bolt group 6, the main car leaning plate 1 is separated from the auxiliary car leaning plate 2, and the oil cylinder 4 is pushed to drive the driven gear 14 and the swing rod 18 so that the auxiliary car leaning plate 2 retracts to the initial position. When pressing, the main sweep 1 drives the auxiliary sweep 2 to move forward, the main sweep 1 presses the container body 8 first, and then the auxiliary sweep 2 presses the container carrier 9.
The beneficial effects of the utility model are that: the lateral leaning function of the open wagon type and the container type is achieved, so that the auxiliary leaning plate leans against the double stress points when leaning against the vehicle, and the safety factor of the leaning against the vehicle is increased.
