Description

Technical Field

[0001] This application relates to the technical field of traction, and particularly to a traction bracket and a traction device. Background Art

[0002] During vehicle transportation (such as road transportation, sea transportation, or railcar transportation) or rescue operations, when a vehicle is being newly manufactured (in the state of not being equipped with a coupler) or repaired (in the state of removing the coupler) and is being towed individually according to the production and manufacturing plan, a traction tooling needs to be installed at the end of the vehicle. After the traction operation is completed, the traction tooling needs to be removed and the coupler needs to be reinstalled.

[0003] This kind of vehicle traction device and traction method requires the disassembly and assembly of the traction tooling, resulting in low traction efficiency and increasing the cost of vehicle new manufacturing or repair. Summary of the Invention

[0004] This application provides a traction bracket and a traction device to quickly achieve the rapid traction of a single vehicle, improve the traction efficiency, and reduce the cost of vehicle new manufacturing and repair. Moreover, during vehicle transportation (such as road transportation, sea transportation, or railcar transportation) or rescue operations, the traction bracket can also be used as a fixed point to improve the transportation or rescue efficiency. In specific scenarios, such as when a vehicle is accidentally collided, the traction bracket deforms to achieve the function of buffering and energy absorption.

[0005] In a first aspect, this application provides a traction bracket, including:

[0006] A main board;

[0007] A connection hole, opened at the connection end of the main board, for cooperating with a mounting pin to form a rotational connection between the main board and the swing arm of the towing vehicle;

[0008] A fixed end, located at the end of the main board far from the connection hole, and the fixed end is fixed to the end of the vehicle body.

[0009] In some embodiments, the end of the connection end far from the fixed end is arc-shaped.

[0010] In some embodiments, the connection hole and the arc-shaped end of the connection end are concentric.

[0011] In another aspect, this application provides a traction device, including:

[0012] A main vehicle body;

[0013] The above-mentioned traction brackets, with multiple numbers, are all fixed to the end of the vehicle body of the main vehicle body through corresponding fixed ends.

[0014] In some embodiments, the fixed end is welded to the end of the vehicle body.

[0015] In this regard, by means of the connection end and the mounting pin of the towing bracket to cooperate with the swing arm of the towing vehicle, the rapid towing of a single vehicle can be achieved quickly, improving the towing efficiency and reducing the manufacturing and maintenance costs of the vehicle. Moreover, during vehicle transportation (such as by road, sea or railcar) or rescue, the towing bracket can also serve as a fixed point to improve the transportation or rescue efficiency. In specific scenarios, such as when the vehicle is accidentally collided, the towing bracket deforms to achieve the effect of buffering and energy absorption. Brief Description of the Drawings

[0028] The fixed end 102 is located at the end of the main board 104 away from the connection hole 103, and moreover, the fixed end 102 is fixed to the vehicle body end 2.

[0029] Specifically, the towing bracket 1 includes: a main board 104, a connection end 101, a fixed end 102, and a mounting pin 4. Among them, both the connection end 101 and the fixed end 102 are ends of the main board 104. Specifically, the connection end 101 is provided with a connection hole 103, and the fixed end 102 is located at the end of the main board 104 far from the connection hole 103. Moreover, when the towing bracket 1 is connected to the vehicle body end 2, the fixed end 102 is fixed to the vehicle body end 2. For example, the fixed end 102 is used for welding to the vehicle body end. In addition, the main board 104 and the towing vehicle swing arm 3 are rotationally connected by the cooperation of the connection hole 103 of the main board 104 and the mounting pin 4, that is, the towing bracket 1 and the towing vehicle swing arm 3 are rotationally linked by the cooperation of the connection hole 103 and the mounting pin 4.

[0030] In another embodiment, the end of the connection end 101 far from the fixed end 102 is arc-shaped.

The axial direction of the through holes is perpendicular to the length direction of the bottom of the U-shaped groove. During operation, the end of the connecting end 101 of the towing bracket 1 that is far from the fixed end 102 (the arc end in the connecting end 101) is located in the U-shaped groove, and the connecting hole 103 is coaxial with the through hole. The mounting pin 4 sequentially passes through the through hole and the connecting hole 103, so that the tractor swing arm and the towing bracket 1 form a rotational connection.

[0039] Thus, through the cooperation of the connecting hole 103 on the towing bracket 1 and the mounting pin 4, the towing bracket 1 and the tractor swing arm 3 form a rotational link, thereby quickly realizing the rapid towing of a single vehicle, improving the towing efficiency, and reducing the cost of vehicle manufacturing and maintenance; moreover, during vehicle transportation (by road, sea or rail vehicle, etc.) or rescue, the towing bracket 1 can also be used as a fixed point to improve the transportation or rescue efficiency; in specific scenarios such as when the vehicle is accidentally collided, the towing bracket 1 deforms to achieve the function of buffering and energy absorption.
