Embodiment Construction

[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0025] Such as Figure 1-Figure 4 The specific embodiment of the airbag type anti-overturning device for a tank truck is shown. The tank truck includes a hub 11, a chassis 2 and a tank 1 supported on the chassis 2 by a support column 10. The tank 1 is generally used to hold and transport liquid . The liquid in the tank 1 is often not full. When the tank truck turns or the heights of the hubs 11 on both sides are inconsistent, the tank truck has a rollover speed Vx, and the line between the center of the tank truck and the hub 11 is equal to the horizontal plane. A roll angle θ is formed, and when the roll angle reaches the rollover critical angle of 90°, the...

Abstract

The invention belongs to the technical field of vehicle safety, and in particular relates to an air bag type anti-tipping device and system for a canned vehicle. The tipping device includes: an air bag assembly and a telescopic axle assembly, the air bag assembly is filled with the upper surface of the liquid in the tank and the tank Between them, the airbag assembly includes a capsule body, a gas generator arranged inside the capsule body, and a fixed block fixed on the upper surface of the capsule body, and the fixed block is fixed to the inner surface of the upper part of the tank; Connected coaxially with the hub, the telescopic axle assembly includes: an inner disc, an outer disc, a hydraulically telescopic shaft interposed between the inner disc and the outer disc, and an outer wheel arranged outside the outer disc; the distance between the outer wheel and the hub is adjusted through the expansion and contraction of the hydraulic telescopic shaft. The tipping system includes: a rollover control ECU unit, a steering wheel angle sensor, a wheel speed sensor, a gas generator, a hydraulically telescopic shaft driver and a brake device; the invention can effectively control the probability of the tank truck tipping over.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, and in particular relates to an airbag type anti-tipping device and system for a canned vehicle. Background technique [0002] There is a lot of liquid in the tanker, and the liquid often cannot fill the tank barrel of the tanker. The tanker has a tipping speed when turning, which may easily cause the upper surface of the liquid to tilt. If the turning speed is large, it will easily cause the tanker to overturn. In addition, if the height of the hubs on both sides of the tanker is inconsistent when driving, it will also cause the liquid in the tank to tilt and cause the tanker to tip over. Contents of the invention [0003] Aiming at the above-mentioned problem that the tanker is easy to tip over when it is turning or the height of the wheel hubs on both sides is inconsistent, an airbag type anti-tipping device for the tanker is designed. [0004] The technical solution adopted by the p...
