Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, and in particular to a semi-trailer with stable support. Background Art

[0002] A semi-trailer is a trailer with an axle placed behind the center of gravity of the vehicle and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and there are many types of semi-trailers, such as 11-meter barn semi-trailers, 13-meter barn semi-trailers, and low-bed semi-trailers. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin. Semi-trailers are mainly used to transport large goods that are large in volume and difficult to split, such as excavators, etc. The fence type is more suitable for pulling fresh goods, such as vegetables, fruits, etc. The box type is more suitable for pulling bulk goods and moisture-proof and more valuable goods. When the semi-trailer is loading or unloading goods, the bucket needs to move, and the movement of the bucket will drive the semi-trailer to move. At this time, the body needs to be firmly supported.

[0003] After searching, the utility model patent with publication number CN208515567U discloses a stably supported landing gear for a semi-trailer, in which the action of the piston rod of the first oil cylinder drives the sleeve to move, and the sleeve drives the fixed frame to move downward, and the movement of the fixed frame drives the load-bearing plate to move, and the load-bearing plate falls to the ground for support. When the bucket is subjected to external force, the sleeve will be driven to move downward, and the sleeve will drive the fixed frame to move. Due to the supporting effect of the ground, the load-bearing plate will support the fixed frame, thereby squeezing the spring, and utilizing the reset function of the spring to reduce the shock of the vehicle body. However, the spring reduces the impact force by expanding the amplitude. The spring absorbs and stores the vibration energy in the compression stroke and releases it in the extension stroke. It cannot consume energy and reduce the shaking amplitude, so that the spring cannot offset the impact force to reduce the shock of the vehicle body. Therefore, a stably supported semi-trailer is needed. Utility Model Content
