[0002] A towing plate is usually used when a gooseneck semi-trailer is connected to a tractor. Most existing tractors are designed as an integrated unit with the frame, and then a towing pin is installed on the towing plate. This design will directly transmit the vibration of the towing pin to the tractor through the towing plate when it is on a bumpy road. In severe cases, the towing pin may be deflected, causing deformation at the connection of the frame, which is extremely inconvenient for later exhaust and maintenance. Utility Model Content

[0005] Furthermore, the top of the mounting seat is rotatably connected to the crossbeam via a pin, and a through hole for penetrating the pin is provided at the top of the mounting seat and the middle of the crossbeam.

[0006] Furthermore, there are multiple mounting seats, which are evenly distributed along the length direction of the adapter seat, and each adapter seat is arranged at the midline position of the adapter seat.

[0007] Furthermore, the mounting seat includes two vertical plates symmetrically distributed with the cross beam as the midline, a support beam is arranged between the two vertical plates, and a reinforcing rib plate connected to the adapter seat is arranged on the outer side of each vertical plate.

[0008] Furthermore, the adapter seat includes a base plate, and side plates are arranged on both sides of the base plate. The base plate and the side plates form a C-shaped installation chamber, and the installation seat is located in the installation chamber.

[0009] Furthermore, a limiting beam located above the side panel is provided at the lower part of the frame, a positioning extension plate located inside the side panel is provided on the lower surface of the limiting beam, and connecting holes are provided on both the side panel and the positioning extension plate.

[0010] Furthermore, the traction connection module includes traction pins arranged on the lower surface of the adapter, and the traction pins are multiple and evenly distributed along the length direction of the adapter.

[0011] The beneficial effects of the utility model are as follows: 1. The traction device for the gooseneck semi-trailer comprises an adapter for connecting a frame and a tractor, a traction connection module for connecting a tractor is installed at the lower part of the adapter, a crossbeam for connecting the adapter is installed at the lower part of the frame, a mounting seat detachably connected to the crossbeam is provided on the adapter, the adapter is detachably connected to the tractor and the frame, and when damage occurs, only the adapter needs to be disassembled and replaced, which can complete the inspection and replacement operations more quickly than the existing integrated connection between the traction module and the frame.

[0012] 2. The adapter and the frame are connected by a pin shaft. The swinging design can reduce the negative feedback of the trailer to the towing trailer when passing through bumps or bad road conditions, making the driver more comfortable, reducing the wear of the connection between the frame and the towing vehicle, and extending the service life of the towing pin.
