Description

Technical Field

[0001] The invention relates to the technical field of traction disks, and in particular to a novel traction disk structure. Background Art

[0002] At present, there are two ways to connect the trailer and the trailer of a full trailer, one is a traction plate structure, and the second is a turntable structure. The traction plate structure is a universal connection method between a tractor and a semi-trailer. A traction plate is fixed on the trailer, a traction pin is welded on the semi-trailer, and a traction plate is arranged between the traction plate and the semi-trailer. The traction pin and the traction plate are locked by the locking mechanism of the traction plate and can be rotated freely; the turntable structure is that the upper turntable is connected to the semi-trailer by bolts, the lower turntable is connected to the trailer by bolts, the middle is rotated by the upper ball and the side ball, and the front is connected to the front semi-trailer by a coupler. The traction plate structure itself has a swing function, so there are two degrees of freedom of swing. If the vehicle runs a little faster, the stability of the rear trailer will be very poor. The slow running speed of the vehicle will cause low efficiency of cargo transportation. The turntable structure can ensure that there is only one degree of freedom for vehicle transportation, but the carrying capacity of the turntable is relatively low, which cannot meet the use of large loads.

[0003] Therefore, it is necessary to provide a new traction disc structure to solve the shortcomings of the prior art. Summary of the invention

[0004] The purpose of the present invention is to avoid the shortcomings of the prior art and provide a new traction plate structure. The present application ensures that there is only rotational freedom between the trailer and the trailer, wherein a friction plate is arranged between the upper traction plate of the trailer and the lower traction plate of the traction trailer, and the lubrication holes opened on the friction plate can store grease to reduce the upper traction plate of the trailer and the lower traction plate of the traction trailer. The overall rotation process is completed by the rotation of the traction pin that penetrates the upper traction plate of the trailer and the lower traction plate of the traction trailer, thereby reducing the up and down swinging of the vehicle operation, and because this structure allows the upper traction plate of the trailer to contact the lower traction plate of the traction trailer over a large area, a greater load-bearing capacity can be guaranteed.

[0005] The above-mentioned purpose of the present invention is achieved through the following technical means.

[0006] A new type of traction disc structure is provided, including a trailer and a tow vehicle, wherein an upper traction plate of a trailer is installed under the trailer, a lower traction plate of a traction trailer is installed on the trailer, a traction pin mounting seat is installed between the upper traction plate of the trailer and the trailer, a traction pin is mounted on the traction pin mounting seat by means of bolts, a fixed steel sleeve is welded to the lower traction plate of the traction trailer as an integral part, an inner lining copper sleeve is arranged inside the fixed steel sleeve, a traction pin is inserted through the inner lining copper sleeve, a spring washer is installed on the part of the traction pin that passes through the inner lining copper sleeve, and the spring washer is fixed externally by means of bolts and nuts.

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

[0008] Specifically, the traction pin is vertically installed below the traction pin mounting seat, and the traction pin vertically penetrates the lower traction plate of the traction trailer to the outside of the inner lining copper sleeve.

[0009] Preferably, the upper traction plate of the trailer is installed in parallel with the lower traction plate of the traction trailer, and a friction plate is installed between the upper traction plate of the trailer and the traction trailer.

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

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

[0012] The present invention ensures that there is only rotational freedom between the trailer and the tow vehicle, wherein a friction plate is arranged between the upper towing plate of the trailer and the lower towing plate of the towing trailer, and the lubrication holes opened on the friction plate can store grease to reduce the rotation of the upper towing plate of the trailer and the lower towing plate of the towing trailer, and the overall rotation process is completed by the rotation of the towing pins penetrating the upper towing plate of the trailer and the lower towing plate of the towing trailer, thereby reducing the up and down swinging of the vehicle operation, and because this structure allows the upper towing plate of the trailer to contact the lower towing plate of the towing trailer over a large area, a greater load-bearing capacity can be guaranteed.

[0031] The present invention is further described in conjunction with the following examples.

[0032] Embodiment 1:

[0033] like Figure 1-2 As shown, a new type of traction plate structure includes a trailer 1 and a tow vehicle 2, an upper traction plate 3 of a trailer is installed below the trailer 1, a lower traction plate 4 of a tow vehicle is installed on the trailer 2, a traction pin mounting seat 5 is installed between the upper traction plate 3 of the trailer and the trailer 1, a traction pin 7 is installed on the traction pin mounting seat 5 through a bolt 6, and the traction pin 7 is fixed to the traction pin mounting seat 5 through the bolt 6, so that the upper traction plate 3 of the trailer and the lower traction plate 4 of the tow vehicle can be connected while ensuring the rotation efficiency, thereby indirectly connecting the trailer 1 with the tow vehicle 2;

[0034] The lower traction plate 4 of the traction trailer is integrally formed and welded with a fixed steel sleeve 8, and an inner lining copper sleeve 9 is arranged inside the fixed steel sleeve 8. The fixed steel sleeve 8 and the inner lining copper sleeve 9 are correspondingly installed directly below the traction pin mounting seat 5. The arrangement of the fixed steel sleeve 8 and the inner lining copper sleeve 9 can provide an installation space for the traction pin 7 on the trailer 2 and increase the stability of the connection of the traction pin 7;

[0035] The traction pin 7 is inserted into the inner lining copper sleeve 9, and the traction pin 7 is vertically installed below the traction pin mounting seat 5, and the traction pin 7 vertically penetrates the traction plate 4 under the traction trailer to the outside of the inner lining copper sleeve 9. A lubrication pipe 14 is installed below the traction pin 7, and the lubrication pipe 14 is inserted between the inner lining copper sleeve 9 and the traction pin 7. The lubrication pipe 14 is externally oiled to ensure lubrication of the traction pin 7 during rotation. A spring washer 10 is installed on the part of the traction pin 7 that passes through the inner lining 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 to prevent the traction pin 7 from loosening and moving when it passes through the inner lining copper sleeve 9, thereby increasing the connection stability of the traction pin 7.

[0036] The upper traction plate 3 of the trailer is installed in parallel with the lower traction plate 4 of the traction trailer. A friction plate 12 is installed between the upper traction plate 3 of the trailer and the traction 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 traction plate 3 of the trailer and the lower traction plate 4 of the traction trailer when the trailer 1 and the trailer 2 rotate, and increase the service life of the overall structure.

[0037] The present application ensures that there is only rotational freedom between the trailer 1 and the trailer 2, wherein a friction plate 12 is arranged between the upper traction plate 3 of the trailer and the lower traction plate 4 of the traction trailer, and the lubrication hole 13 opened on the friction plate 12 can store grease to reduce the upper traction plate 3 of the trailer and the lower traction plate 4 of the traction trailer, and the overall rotation process is completed by the rotation of the traction pin 7 penetrating the upper traction plate 3 of the trailer and the lower traction plate 4 of the traction trailer, thereby reducing the up and down swinging of the vehicle operation, and because this structure allows the upper traction plate 3 of the trailer to contact the lower traction plate 4 of the traction trailer over a large area, a greater load-bearing capacity can be guaranteed.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
