Embodiment 1

[0030] A kind of anti-rollover tank car, such as figure 1 , figure 2 As shown, the front half of the tank is connected with the chassis of the car body through the hinge 103, and the second half of the tank is connected with the horizontal shaft of the rear wheel row through the hinge and the hydraulic cylinder; The plunger type hydraulic cylinder 107, the expansion and contraction of the hydraulic cylinder 107 can make the tank body swing to a certain extent to both sides, so as to achieve the purpose of balancing the vehicle body. Servo control device 101 is arranged at the forefront of the tank body, which can monitor its own state and control the hydraulic system in real time while the car body is moving, and adjust the balance of the car body.

[0031] hydraulic system such as image 3 As shown, the one-way quantitative pump 206 pumps the hydraulic oil from the oil tank to a pair of interlocked electro-hydraulic servo valves 202 through the oil delivery pipe; Through ...

Embodiment approach

[0039] ●As in Embodiment 1, the expansion and contraction length of the left and right hydraulic cylinders is used to drive the tank to swing; as other implementations, other transmission forms can also be used, such as driving the tank to swing by driving the twisted shaft to rotate. If the front end or rear end of the tank is equipped with a deceleration mechanism, the deceleration mechanism drives the twisted shaft to rotate; the deceleration mechanism is driven by a motor.

[0040] ●In addition to the hydraulic power form in Embodiment 1, gas power, electric power and other power forms can also be used.

[0041] ●The bracket in Example 1 is used to connect the vehicle body and the tank, and realize the hinge connection between the vehicle body and the tank; as other implementation modes, it can also be replaced by other transfer structures. The triangular support in Embodiment 1 raises the tank to a certain height, which is beneficial to the left and right swing of the tan...

Abstract

The invention relates to a rollover preventing tank truck. A truck body is hinged to a tank, a hinged axis is in the truck body extending direction, a driving mechanism is arranged between the truck body and the tank, and the driving mechanism is used for adjusting the tank to rotate along the hinged axis. The tank rotates along the hinged axis, so as to carry out real time adjustment to the state of the truck body, and prevent the occurrence of rollover.

Description

technical field [0001] The invention relates to an anti-rollover tank car. Background technique [0002] Large vehicles are prone to rollover accidents due to their large mass, high inertia, and high center of gravity. Existing anti-rollover measures mainly adopt the safety bag device to open the air bag between the car body and the road surface to prevent damage to the car body when a rollover occurs. [0003] The above-mentioned anti-rollover scheme is an emergency measure when the car body has rolled over, and it is necessary to judge whether the car body rolls over by judging the inclination of the car body. Judgment criteria must be chosen carefully to avoid deploying the airbag when protection is not required, or failing to deploy the airbag in time when protection is required. [0004] Tank trucks can also use elliptical cross-section tanks to reduce the risk of rollover by lowering the vehicle's center of gravity. [0005] Existing schemes cannot really avoid the ...
