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 for a traction semi-trailer. The anti-folding support is connected between the back of the tractor and the front end of the semi-trailer through a first base and a second base. One end of a support rod is connected to the first base. One end is connected to the tension pressure sensor, the other end of the tension pressure sensor is connected to the hydraulic rod piston rod, the hydraulic rod cylinder is connected to the second base, the top side of the hydraulic rod is connected to a two-position two-way solenoid valve, and the support A coil spring is arranged between the rod and the first base. The semi-trailer anti-folding bracket of the present invention spans between the tractor and the semi-trailer, and is applicable to various types of traction semi-trailers. The invention can effectively prevent the folding accident of the traction semi-trailer when driving at high speed, and improve the transportation safety. It also improves driving comfort.
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...
