Embodiment

[0027] Such as Figure 1~8 As shown, an anti-overturning device for a van type truck includes a spoiler telescopic mechanism 1, a distance sensor 2, a pressure sensor 3, and a controller 4. The spoiler telescopic mechanism 1 includes a box body 11 and a spoiler 12, The box body 11 is fixedly provided with a cover plate 112, the spoiler telescopic mechanism 1 is located below the cover plate 112, the box body 11 is fixedly connected to the truck body 5, and the box body 11 is provided with a driving mechanism The spoiler 12 is located on both sides of the upper part of the truck body 5, and the spoilers 12 on both sides are symmetrically arranged. The cross-sectional shape of the spoiler 12 is opposite to the cross-sectional shape of the wing. The air flow speed on the lower surface of the flow plate 12 is faster and the pressure is low, and the air flow speed on the upper surface of the spoiler 12 is slower and the pressure is high. The pressure difference between the two forms ...

Abstract

The invention belongs to the technical field of truck transportation, in particular to a van anti-overturning device and a control method thereof. The van anti-overturning device comprises a spoiler telescopic mechanism, the distance sensors, the pressure sensors and a controller, and the spoiler telescopic mechanism comprises a box body and the spoilers; the box body is fixedly connected with thetruck carriage body, a driving mechanism is arranged in the box body, and the spoilers are located at the two sides of the upper portion of the truck carriage body; the spoilers at the two sides aresymmetrically arranged, the section shapes of the spoilers are opposite to the section shapes of the wings up and down, and the driving mechanism drives the spoilers at the two sides to move away fromor close to each other in a horizontal direction; the distance sensors are arranged at the two sides of the truck carriage body, the pressure sensors are arranged at the two sides of the truck carriage body, and the controller is in signal connection with the driving mechanism, the distance sensors, the pressure sensors and a speed measuring mechanism of the truck.

Description

Technical field [0001] The invention belongs to the technical field of truck transportation, and in particular relates to an anti-overturning device for a van type truck and a control method thereof. Background technique [0002] With the continuous enhancement of my country's comprehensive national strength, the mileage of my country's high-grade highways is increasing rapidly, and the design speed is also getting higher and higher. At present, many highways are paved in the form of viaducts, and quite a few sections are in open and sparsely populated open areas. The result of this is that cars driving on these empty high-grade roads are easily affected by the natural environment in the open fields. Except for traffic accidents caused by humans, unpredictable cross winds on highways are also the culprit in many traffic accidents. The culprit. [0003] The side of the van has a large windward surface. When running in a crosswind state, its aerodynamic characteristics change signi...
