Problems solved by technology

In the case of uneven road surface or continuous ups and downs of the field road, it will cause the front of the car to tilt on one side, which may cause the connector to break and bring certain risks to driving.
In addition, the existing connection mode does not use a buffer device, so when the tractor is running at high speed, if it brakes suddenly, due to the effect of inertia, the trailer may rush forward or overturn too much, which will cause danger

Embodiment Construction

[0028]The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0029] Figure 1-Figure 9 A preferred embodiment of a tractor connection structure of the present invention is shown, and the connection structure includes a first connection part 1 , a second connection part 2 and a third connection part 3 .

[0030] The first connecting part 1 is rotatably connected to the head of a tractor through a vertical rotating shaft 5 , so that the first connecting part 1 can rotate around the vertical rotating shaft 5 . The second connecting part 2 is rotatably connected to the first connecting part 1 through the first rotating shaft 11 in the horizontal direction, so that the second connecting part can rotate around the first rotating shaft 11, when the tractor moves along a stra...

Abstract

The invention provides a connection structure for a tractor. The connection structure comprises a first connection portion, a second connection portion and a third connection portion. The first connection portion is suitable for being rotatably connected with a head portion of the tractor through a vertical rotating shaft, the second connection portion and the first connection portion are in rotatable connection through a first rotating shaft in the horizontal direction, and the third connection portion and the second connection portion are in rotatable connection through a second rotating shaft in the horizontal direction. The extension direction of the second rotating shaft is perpendicular to that of the first rotating shaft, and the third connection portion is suitable for being connected with a trailer portion of the tractor. Relative rotation between the first connection portion and the second connection portion is locked or unlocked through a first locking device, and relative rotation between the second connection portion and the third connection portion (3) is locked or unlocked through a second locking device. Springs are arranged between the second connection portion and the third connection portion and mainly used for buffering, and extension directions of the springs are perpendicular to the second rotating shaft.

Description

technical field [0001] The invention relates to a tractor connecting structure. Background technique [0002] Generally, the connection structure between the tractor and the trailer adopts a hard connection, and only there is a degree of freedom on the horizontal plane to realize left and right turns. In the case of uneven road surface or continuous ups and downs of the field road, it will cause the front of the car to tilt on one side, which may cause the connector to break and bring certain risks to driving. In addition, the existing connection mode does not use a buffer device, so when the tractor is running at high speed, if it brakes suddenly, due to the inertia, it may cause the trailer to rush forward or overturn too much, which will cause danger. Contents of the invention [0003] The main purpose of the present invention is to provide a tractor connection structure, which can realize the multi-angle rotation of the front and rear parts of the tractor, so that it ...
