A folding semi-trailer

Abstract

The invention discloses a folding semi-trailer. By setting the rear half of the semi-trailer with tires to be foldable, and setting a support frame with a rotatable angle greater than 90° on the fixed vehicle body, a hydraulic rod is used for Its rotation provides power, and the traction part is set on the fixed car body. The traction part can pull up the folding car body through the traction rope and the support frame. The support frame can provide support for the folding car body, so as to realize the folding and laying down of the car body. Reduce the energy consumption of the semi-trailer on the way back and reduce the wear of the tires; at the same time, the complete part of the semi-trailer is provided with support beams, support columns and lock parts. Through the cooperation between them, it provides support and fixation for the hinges. The car body is fastened and stable when it is put down to load the goods; at the same time, there is an electromagnetic plate at the hinge, and an elastic connection is installed on the support column with an electromagnetic buffer plate, which increases the service life of the components and makes the car body more stable when driving. of stability.

Description

Technical field [0001] The present invention relates to the field of semi-trailer, in particular to a folded semi-trailer. Background technique [0002] The semi-trailer includes a tractor and a trailer, and half of the trailer is taken on the traction saddle on the rear of the tractor, and the bridge behind the tractor is subjected to a portion of the trailer. Since semi-trailer is convenient to disassemble, it is convenient to transport, it is widely used in our freight industry in my country. [0003] Some shipments large half-trailer, because the body is too large, which generally has multiple sets of tires, and when the semi-trailer is shipped, the air-load state will waste a lot of energy, and Since it is in an air-loaded state, the body does not need too much tire to support. Under the prior art, the transport team generally uses a semi-trailer to load another semi-trailer when returning, but due to the substantially the same length of the semi-trailer, the loaded semi-tra...

AI Technical Summary

Problems solved by technology

Under the existing technology, the transport fleet generally uses one semi-trailer to load another semi-trailer when returning. However, since the length of the semi-trailers is basically the same, part of the loaded semi-trailer will leak out of the car body, and there will be risks. , and a single semi-trailer cannot be loaded. In this way, more energy will be wasted on the way back, and unnecessary wear and tear will be caused on the tires.
