Description

Technical Field

[0001] This utility model relates to the field of traction disc technology, and in particular to a novel traction disc structure. Background Technology

[0002] Currently, there are two connection methods between the trailer and the tractor unit in a full trailer: a traction disc structure and a turntable structure. The traction disc structure is a common connection method between the tractor unit and the semi-trailer. A traction disc is fixed to the trailer, and a traction pin is welded to the semi-trailer. There is a traction plate between the traction disc and the semi-trailer. The locking mechanism of the traction disc locks the traction pin to the traction disc and ensures free rotation. The turntable structure has an upper turntable connected to the semi-trailer by bolts, and a lower turntable connected to the trailer by bolts. Rotation is achieved by upper and side ball bearings in the middle. A coupler is located at the front to connect to the front semi-trailer. The traction disc structure itself has a swing function, so there are two degrees of freedom in the swing. If the vehicle speed is slightly faster, the stability of the trailer will be very poor. If the vehicle speed is slow, the cargo transportation efficiency will be low. The turntable structure can ensure that the vehicle has only one degree of freedom in transportation. However, the load-bearing capacity of the turntable is relatively low and cannot meet the needs of heavy load-bearing applications.

[0003] Therefore, it is essential to provide a novel traction disc structure to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a novel towing disc structure to overcome the shortcomings of the prior art. This application ensures that there is only rotational freedom between the trailer and the tractor. A friction plate is provided between the upper towing plate of the trailer and the lower towing plate of the tractor. The lubrication holes on the friction plate can store grease to reduce the friction between the upper towing plate of the trailer and the lower towing plate of the tractor. The overall rotation process is completed by the rotation of the towing pin that runs through the upper towing plate of the trailer and the lower towing plate of the tractor, which reduces the up-and-down sway of the vehicle. Furthermore, since this structure allows for a large-area contact between the upper towing plate of the trailer and the lower towing plate of the tractor, it can ensure a greater load-bearing capacity.

[0005] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0006] A novel towing disc structure is provided, including a trailer and a tractor. An upper towing plate is installed under the trailer, and a lower towing plate is installed on the tractor. A towing pin mounting seat is installed between the upper towing plate and the trailer. A towing pin is installed on the towing pin mounting seat by bolts. The lower towing plate of the tractor is integrally formed and welded with a fixing steel sleeve. An inner copper sleeve is provided inside the fixing steel sleeve. The towing pin is inserted through the inner copper sleeve. A spring washer is installed on the part of the towing pin that passes through the inner copper sleeve. The spring washer is externally fixed by bolts and nuts.

[0007] Specifically, the fixed steel sleeve and the inner copper sleeve are installed directly below the traction pin mounting seat.

[0008] Specifically, the towing pin is vertically installed below the towing pin mounting seat, and the towing pin vertically passes through the lower towing plate of the towing trailer to the outside of the inner copper bushing.

[0009] Preferably, the upper towing plate of the trailer and the lower towing plate of the tractor are installed parallel to each other, and a friction plate is installed between the upper towing plate of the trailer and the tractor.

[0010] Specifically, lubrication holes are evenly distributed on the friction plate.

[0011] Specifically, a lubrication pipe is installed below the traction pin, and the lubrication pipe is inserted between the inner copper bushing and the traction pin.

[0012] This invention ensures that the trailer and tractor have only rotational freedom. A friction plate is provided between the upper traction plate of the trailer and the lower traction plate of the tractor. The lubrication holes on the friction plate can store grease to reduce the friction between the upper traction plate of the trailer and the lower traction plate of the tractor. The overall rotation process is completed by the rotation of the traction pin that runs through the upper traction plate of the trailer and the lower traction plate of the tractor, which reduces the up-and-down sway of the vehicle. Furthermore, because this structure allows for a large contact area between the upper traction plate of the trailer and the lower traction plate of the tractor, it can ensure a greater load-bearing capacity.

[0031] The present invention will be further described in conjunction with the following embodiments.

[0032] Example 1:

[0033] like Figure 1-2 As shown, a novel traction disc structure includes a trailer 1 and a trailer 2. An upper trailer traction plate 3 is installed below the trailer 1, and a lower trailer traction plate 4 is installed on the trailer 2. A traction pin mounting seat 5 is installed between the upper trailer traction plate 3 and the trailer 1. A traction pin 7 is installed on the traction pin mounting seat 5 by bolts 6. After the traction pin 7 is fixed to the traction pin mounting seat 5 by bolts 6, it can connect the upper trailer traction plate 3 and the lower trailer traction plate 4 while ensuring rotation efficiency, thus indirectly connecting the trailer 1 and the trailer 2.

[0034] The lower traction plate 4 of the tractor is integrally formed and welded with a fixed steel sleeve 8. The fixed steel sleeve 8 has an inner copper sleeve 9 inside. The fixed steel sleeve 8 and the inner copper sleeve 9 are installed directly below the traction pin mounting seat 5. The fixed steel sleeve 8 and the inner copper sleeve 9 provide installation space for the traction pin 7 on the trailer 2, while also increasing the stability of the connection of the traction pin 7.

[0035] The traction pin 7 is inserted through the inner copper sleeve 9. The traction pin 7 is vertically installed below the traction pin mounting seat 5 and vertically passes through the lower traction plate 4 of the towing trailer to the outside of the inner copper sleeve 9. A lubrication pipe 14 is installed below the traction pin 7. The lubrication pipe 14 is inserted between the inner copper sleeve 9 and the traction pin 7. The lubrication pipe 14 can be externally lubricated to ensure lubrication when the traction pin 7 rotates. A spring washer 10 is installed on the part of the traction pin 7 that passes through the inner copper sleeve 9. The spring washer 10 is externally fixed by bolts 6 and nuts 11 to clamp the bottom of the traction pin 7, preventing the traction pin 7 from loosening and moving after passing through the inner copper sleeve 9, and increasing the connection stability of the traction pin 7.

[0036] The upper towing plate 3 of the trailer and the lower towing plate 4 of the trailer are installed in parallel. A friction plate 12 is installed between the upper towing plate 3 of the trailer and the trailer 2. Lubrication holes 13 are evenly opened on the friction plate 12. The opening of the lubrication holes 13 can store grease on the friction plate 12, reduce the friction between the upper towing plate 3 of the trailer and the lower towing plate 4 of the trailer when the trailer 1 and the trailer 2 rotate, and increase the service life of the overall structure.

[0037] This application ensures that the trailer 1 and the trailer 2 have only rotational freedom. A friction plate 12 is provided between the upper trailer traction plate 3 and the lower trailer traction plate 4. The lubrication holes 13 on the friction plate 12 can store grease to reduce the vertical sway of the vehicle. The overall rotation process is completed by the rotation of the traction pin 7 that runs through the upper trailer traction plate 3 and the lower trailer traction plate 4, which reduces the vertical sway of the vehicle. Furthermore, because this structure allows for a large contact area between the upper trailer traction plate 3 and the lower trailer traction plate 4, it can ensure a greater load-bearing capacity.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
