The tank body 2 is mounted on the frame 1 for carrying the hazardous chemicals to be transported. Since the distance between the two longitudinal beams 11 of the vehicle frame 1 is increased, compared with the vehicle frame 1 in the related art, the vehicle frame 1 in this embodiment can lower the tank body 2 as a whole, that is, the tank body 2 The center of mass of the transport tanker is lowered, and the height of the center of mass of the transport tanker is reduced, which improves the rollover resistance of the transport tanker.

The third connecting pipe 35 is connected between the rear end damping valve blocks 321 on both sides of the frame 1 .

Through the above-mentioned connecting pipes 35, the middle damping valve block 321 on both sides of the frame 1 and the rear damping valve block 321 are communicated, and then the hydraulic shock absorbers 322 on both sides of the frame 1 are communicated, so that the two sides of the frame 1 are connected.

The hydraulically interconnected suspension also includes accumulators 34 corresponding to the two suspension mechanisms. In this embodiment, the two accumulators 34 are arranged on both sides of the rear end of the frame 1 . Specifically, the accumulator 34 is connected with the rear end damping valve block 321 on the same side. The accumulator 34 is provided with an oil pressure sensor for receiving the real-time pressure of the hydraulic shock absorber 322 of the corresponding suspension mechanism and comparing it with a preset pressure value. When the real-time pressure is less than or greater than the preset pressure, that is, when the oil pressure of the hydraulic shock absorber 322 is insufficient or excessive, it will automatically trigger, release or compress the air, and play a role in maintaining the pressure of the hydraulic shock absorber 322, thereby ensuring the The oil pressure is stabilized when parking on a certain slope. In this embodiment, the accumulator 34 is an air accumulator 34 .

The accumulators 34 on both sides of the frame 1 are connected through the communication between the rear damping valve blocks 321. Therefore, when one of the accumulators 34 fails, the other side can be adjusted to ensure that the available.

The hydraulic interconnected suspension works as follows:

When the right side of the transport tank truck is raised, the axle on the right side is lifted up as a whole, and the telescopic rod of the hydraulic shock absorber 322 is moved upward, thereby reducing the space of the pressure chamber and increasing the hydraulic pressure, while the right side is moved upward. The hydraulic oil passes through the first connecting pipe 35, the second connecting pipe 35 and the third connecting pipe 35, from the middle damping valve block 321 on the right side and the rear damping valve block 321 to the middle damping valve block 321 on the left side and the rear damping valve block 321 on the left side. The end damping valve block 321 is injected to reduce the oil pressure on the right side, which in turn lowers the right side, thereby lowering the center of mass of the tank body 2 . The damping valve block 321 on the right is pressurized by the accumulator 34 on the right, and the pressure on the right is maintained.

The hydraulic shock absorber 322 on the left side receives the hydraulic oil injected from the right side through the middle damping valve block 321 and the rear damping valve block 321, so that the hydraulic pressure on the left side increases, so that the telescopic rod extends, and the left side is also integrated. The lift is carried out, thereby slowing down the rollover tendency of the transport tanker, keeping the transport tanker stable, and effectively suppressing the rollover of the transport tanker, thereby preventing rollover and ensuring transportation safety.

That is, when the right side is raised, the hydraulic oil on the right side is injected into the left side through the connection of the elastic mechanisms on both sides, so that the center of mass on the right side is lowered. At the same time, lift the left side, so that the height of the center of mass of the left and right sides is equal, and the tendency to roll over is slowed down. The hydraulic oil on the left side flows into the accumulator 34 on the left side, the pressure is released, and the pressure on the left side is maintained.

When the left side of the transport tanker is raised, the principle is referred to above, and will not be repeated here.

When the tanker passes through the uneven road, the hydraulic oil in the hydraulic shock absorber 322 on one side of the frame 1 is influenced by the reaction force fed back by the wheels passing the road, from one damping valve block 321 to the other damping valve on the same side Hydraulic oil is delivered in block 321 and maintained at pressure by accumulator 34 . For example, when the wheel on the right side where the front hydraulic shock absorber 322 is located passes the uneven road, the middle damping valve block 321 sends the rear hydraulic shock absorber 322 and the rear damping valve to the rear hydraulic shock absorber 322 and the rear damping valve according to the actuating force of the front hydraulic shock absorber 322 The block 321 outputs pressure, pushes the hydraulic oil to flow through the plurality of oil pipes 323 to adjust the actions of the front hydraulic shock absorber 322 , the middle hydraulic shock absorber 322 and the rear hydraulic shock absorber 322 , and is maintained by the accumulator 34 . It is ensured that the working pressures of the multiple hydraulic shock absorbers 322 on one side of the frame 1 are consistent, to avoid the torsion of the transport tanker, and to flexibly apply to different road surfaces.

In other embodiments, there may be only two axles. In this case, the suspension mechanism on one side of the frame 1 includes two hydraulic shock absorbers 322 and a damping valve block 321, and the two hydraulic shock absorbers 322 are respectively arranged at the front end and the rear end. , the damping valve block 321 is arranged in the middle of the frame 1 . The damping valve blocks 321 on both sides of the frame 1 communicate with each other through the two connecting pipes 35 . The accumulators 34 on both sides of the frame 1 are connected correspondingly to the two damping valve blocks 321 .

In another embodiment, there may also be four axles. In this case, each suspension mechanism includes two damping valve blocks 321 and four hydraulic shock absorbers 322, that is, a hydraulic damping valve block 321 is connected to the rear end of each side. The shock absorber 322 is sufficient.
