[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In the use of traditional trailer traction frames, it is mainly supported by welding or riveting steel frames. During the support process, there is no shock-absorbing measure in the area on which the heavy objects are carried. When towing, the contact with the ground is too strong, resulting in loosening of the connection parts of the traction area. In addition, due to the manufacturing process, strong vibrations can easily cause fractures in the welding or riveting parts. Based on this, the present application provides a trailer traction frame, including a frame 1 constituting the traction frame and at least one group of support components 2 arranged in the frame 1;

[0030] A shock absorbing assembly 3 is arranged in the middle of the frame 1, and the shock absorbing assembly 3 includes a card frame 34, and a shock absorbing steel plate 32 is arranged in the middle of the inner side of the card frame 34, and springs 33 are arranged at both ends of the shock absorbing steel plate 32 for supporting the supporting plate above it;

[0031] A support arm 31 is provided on one side of the card frame 34 and is adapted to the bottom of the supporting plate.

[0032] The trailer tongue comprises a main frame 1, which is used to support the entire structure and is connected to the tractor.

[0033] At least one set of supporting components 2 is arranged inside the frame 1 , and the function of the components is to enhance the stability and traction ability of the frame 1 .

[0034] A shock absorbing assembly 3 is provided in the middle of the frame 1. The function of the shock absorbing assembly 3 is to reduce the impact and vibration caused by uneven ground during the traction process, thereby protecting the traction frame and connecting parts.

[0035] The shock absorbing assembly 3 includes a structure called a card frame 34, and a shock absorbing steel plate 32 is arranged in the middle of the inner side of the card frame 34. The design of this steel plate can effectively absorb and disperse the energy from the road vibration.

[0036] The two ends of the shock-absorbing steel plate 32 are respectively provided with springs 2 33 (two springs), which are used to support the supporting plate located above it. The design of the spring can adaptively provide supporting force and shock-absorbing effect according to the load change during traction.

[0037] One side of the card frame 34 is equipped with a bracket arm 31, which is adapted to the bottom of the supporting plate to ensure that the shock absorbing assembly 3 is firmly fixed in the frame 1 and can effectively transmit the traction force to the entire structure.

[0038] The combination of the shock-absorbing steel plate 32 and the spring effectively reduces the impact and vibration of the trailer draw frame caused by road vibration during driving, which not only increases the driving comfort, but also prolongs the service life of the trailer draw frame and connecting parts.

[0039] The combination of the clamp frame 34 and the bracket arm 31 provided inside the frame 1 ensures the stability of the entire trailer traction frame during traction. The design of the bracket arm 31 enables the shock absorbing assembly 3 to evenly distribute the load, reducing the risk of local stress concentration.

[0040] The selection of springs takes into account the changes in different road conditions and traction loads, so that the trailer drawbar can operate stably in various environments while ensuring the safety and reliability of the connecting parts.

[0041] The damage to the trailer draw frame caused by vibration and impact is reduced, and the service life of the overall structure is extended.

[0042] Through the design of the card frame 34 and the support arm 31, the traction frame can remain stable when driving at high speed or in complex road conditions, reducing the risk of accidental falling off or damage, reducing the vibration of the driver and cargo, and improving driving comfort and safety.

[0043] See also Figure 1 , Figure 2 The frame 1 includes a frame body 11, one end of which is provided with two symmetrically arranged reinforcing members 12, and a connecting member is provided between the two reinforcing members 12 for connecting with a trailer.

[0045] Two groups of symmetrical contact rods 15 are arranged at the bottom of the frame 11 near the reinforcing member 12. The contact rods 15 are sleeved with springs 14 to provide shock-absorbing support for the frame 11 when it is parked.

[0046] The main part of the trailer traction frame has two symmetrical reinforcements 12 at one end, which are used to connect and support the entire structure. The connector between the reinforcements 12 is designed to allow a safe connection between the trailer and the tractor. The baffle 13 is located at the other end of the frame 11 and is combined with the top of the frame 11 by bolts. Its function is to provide additional structural support and protection to ensure the stability and safety of the connection part.

[0047] Two sets of symmetrical contact rods 15 are arranged near the bottom of the reinforcement 12, and springs 14 are sleeved on these rods. The design of the springs allows them to play a shock-absorbing support role when the traction frame is parked, reducing the impact of vibration on the frame 11 and protecting the entire structure from damage.

[0048] Through the design of the reinforcement member 12, the connecting member and the baffle 13, the overall structural strength and stability of the trailer traction frame are greatly enhanced, ensuring the safe connection and traction effect during the traction process.

[0049] The provision of the spring 14 effectively reduces the risk of damage to the trailer traction frame due to ground vibration when the trailer traction frame is parked, protects the integrity of the frame body 11 and the connecting parts, and prolongs the service life.

[0050] The design takes maintenance convenience into consideration. For example, the baffle 13 and the connecting parts are fixed by bolts, which makes maintenance and replacement simple and quick, reducing maintenance time and cost.

[0051] The overall structural design ensures stability and reliability during towing, reduces the risk of accidental breakage or falling off, and improves driving safety and comfort.

[0055] A group of support components 2 are arranged inside the frame 11 of the trailer traction frame, and their function is to strengthen the overall structural stability and load-bearing capacity of the frame 11 .

[0056] The support assembly 2 is symmetrically arranged with the inner side of the frame 11 through the clamping frame 34 of the shock absorbing assembly 3, thereby ensuring balanced support and effective mechanical support.

[0057] The support assembly 2 includes a combination of a telescopic assembly 21 and a resisting block 22. The resisting block 22 is located at both sides of the frame 11 and is vertically combined with the telescopic assembly 21. The contact area between the support assembly 2 and the frame 11 is increased, and the overall structural stability is improved.

[0058] The positioning hole is plug-connected with the telescopic rod of the telescopic assembly 21 , ensuring the fixed position and adjustability of the support assembly 2 in the frame body 11 .

[0059] The symmetrical arrangement of the support assembly 2 and its close integration with the inner side of the frame body 11 effectively enhance the overall torsion resistance and structural stability of the trailer traction frame.

[0060] The design of the clamping frame 34 and the abutment block 22 of the shock-absorbing assembly 3 effectively reduces the vibration and impact of the trailer traction frame caused by road vibration during driving, thereby extending the service life of related components.

[0061] The design of the positioning holes allows the support assembly 2 to be easily installed, adjusted and maintained, thereby reducing the time and labor costs during the maintenance process.

[0062] The reasonable layout and structural combination of the support assembly 2 enable the trailer drawbar to remain stable when towing a large load, thereby reducing the risk of accidents caused by structural instability.
