Problems solved by technology
When the traction semi-trailer is turning, braking at high speed or due to the lateral force of gravity caused by the road gradient, the folding phenomenon is easy to occur, which will cause the vehicle to lose its steering ability and cause major safety accidents
At present, there are not many anti-folding devices designed for the folding phenomenon of semi-trailers, and folding accidents of towing semi-trailers still often occur

The invention discloses an anti-folding support of a traction semitrailer. The anti-folding support is connected between the back face of the tractor and the front end face of the semitrailer throughthe first base and the second base. One end of a supporting rod is connected to the first base, the other end of the supporting rod is connected with a tension and pressure sensor, the other end of the tension and pressure sensor is connected with a piston rod of a hydraulic rod, a cylinder body of the hydraulic rod is connected with the second base, the side face of the top end of the hydraulic rod is connected with a two-position two-way electromagnetic valve, and a spiral spring is arranged between the supporting rod and the first base. The semitrailer anti-folding support is connected between a tractor and a semitrailer in a bridging mode, can be suitable for various traction semitrailer types, can effectively prevent the traction semitrailer from being folded when the traction semitrailer runs at a high speed, and can improve the driving comfort while improving the transportation safety.
Description
technical field [0001] The invention relates to the technical field of traction semi-trailers, in particular to an anti-folding support for traction semi-trailers. Background technique [0002] With the rapid development of my country's logistics industry, the application of traction semi-trailers is becoming more and more extensive, but there are more and more folding accidents of traction semi-trailers. When the towing semi-trailer is turning, braking at high speed or due to the gravity lateral force caused by the road gradient, the left and right wheels are prone to folding, which will cause the vehicle to lose its steering ability and cause major safety accidents . At present, there are not many anti-folding devices designed for the folding phenomenon of semi-trailer tractors, and folding accidents of tractor semi-trailers still often occur. [0003] To sum up, it is necessary to design an anti-folding device for towing semi-trailers to avoid folding accidents and redu...
