Description

Technical Field

[0001] The utility model belongs to the technical field of oil tanker trucks, and in particular relates to an oil tanker truck with an air suspension structure. Background Art

[0002] Oil tank trucks are also called mobile refueling trucks, computer tax-controlled refueling trucks, oil tank trucks, oil loading trucks, oil transport trucks, garbage oil trucks, oil transport trucks, and edible oil transport trucks. They are mainly used for the transportation and storage of oil derivatives. At the same time, with the development of science and technology and the improvement of people's living standards, there are higher requirements for the comfort of oil tank trucks. Air suspensions containing air springs are also increasingly widely used in oil tank trucks. Compared with the commonly used leaf spring air suspensions in the past, drivers have a better driving experience.

[0003] In order to ensure the stable transportation of oil products, multiple baffles are usually installed inside the oil tank to prevent the oil from shaking and fluctuating violently during transportation. The baffles can divide the liquid in the oil tank into multiple small areas, reduce the movement of the liquid, and thus stabilize the liquid in the oil tank, which also helps to reduce the instability of the tank truck during driving.

[0004] However, during the actual transportation process of the tanker, when the vehicle is started or stopped, the tank body is prone to shake due to inertia and the internal oil moves due to inertia. The inertial movement of the oil will impact the internal baffle, causing damage to the baffle and affecting the subsequent normal use of the tanker. Utility Model Content

[0033] When the liquid in the tank body sways and the liquid flow hits the baffle, the rebound plate on the baffle can block part of the impact force, and the U-shaped metal plate and the shock-absorbing spring connected to the rebound plate offset the impact force received by the rebound plate, so that the rebound mechanism plays a better role in preventing the baffle from being damaged by the impact. The side of the rebound plate is set to be wavy, which expands the area of ​​the rebound plate that receives the impact force of the liquid flow and improves its effect of resisting the impact force of the liquid flow. The side of the reinforcement plate is set with an arc plate that covers the rebound mechanism, which not only plays the purpose of protecting the rebound mechanism, but also increases the contact area between the baffle and the liquid flow, effectively improving the effect of the baffle to resist the impact force of the liquid flow, and the through hole on the reinforcement plate provides a passage for the liquid to flow to the liquid flow channel.
