Installation secret of automobile tailboard

With the continuous development of my country's economy, the logistics industry has also continued to grow and develop in recent years, which will also further increase the market's demand for automotive tailgates. As a car component that most logistics and freight companies are keen on, the car tailboard has an indispensable and important position in today's society. In order to make more people understand the tailgate of the car, the editor will explain the basic working principle and use method of the tailgate of a hydraulic car in detail today!

The automobile hydraulic tail plate is a multi-rod mechanical mechanism that adopts electric control and hydraulic drive. It is mainly composed of a lifting cylinder and a tail plate. When the length of the closing door and the lifting arm are equal, a parallel four-bar mechanism is formed, which keeps the tail plate consistent with the horizontal plane, and ensures that the tail plate is consistent with the water surface during loading and unloading.

The construction and working principle of the hydraulic system is also very simple: the tail plate of a hydraulic automobile is generally composed of an overflow valve and a two-position two-way electromagnetic reversing valve, which are mainly used to construct a safety circuit and an unloading circuit for the hydraulic system. The function of the two-position four-way reversing valve is to ensure the interlocking of the lifting and closing actions, because of the interlocking during the ascending process, because during the lifting process, if there is a bad condition in the upward turning cylinder, the cargo may slip down. , And when we use the tail plate of the car to lower it, the balance valve controls the sliding motion so that the tail plate can drop at a uniform speed, ensuring the safety and stability of the cargo. In this way, the tailgate of the car can work efficiently and safely in a stable state.

Let's take a look at the operability of the car tailgate. As a car auxiliary tool with convenience as the main feature, the operation is of course the simpler the better. When loading goods, first press the up button to raise the level of the tail plate, and the tail plate will rise at a uniform speed, with an average speed of 60 to 80 millimeters per second. During the ascent process, the tailboard can be adjusted automatically to ensure that it is consistent with the ground level, and is prevented from being damaged during operation due to improper operation, which may cause damage to personnel and goods. When the tail plate rises in line with the car panel, the lifting action starts to stop. At this time, the cargo can be pulled into the carriage to complete the loading process. It can be said that the operation is truly safe and simple, with one step in place.

One thing to mention here is that some users have reported that the tailgate of a hydraulic vehicle sometimes stops rising when it reaches a certain height. Dongguan car tail plate tells you the reason: this phenomenon is not because the tail plate is malfunctioning, nor is it height limitation, but because the travel switch is installed inside. The travel switch is also called the limit switch, which is used to control the travel and limit protection of mechanical equipment.

In actual production, the travel switch is installed in a pre-arranged position. When the module mounted on the moving part of the production machinery hits the travel switch, the contact of the travel switch will act to realize the switching of the circuit. Therefore, the travel switch is an electrical appliance that switches the circuit according to the travel position of the moving part, and its principle of action is similar to that of a button. Travel switches are widely used in various types of machine tools and hoisting machinery to control their travel and carry out terminal limit protection, so that users do not need to use them but worry about any mistakes in operation.

In the same way, when unloading the cargo, just press the down button lightly to turn it on, and it will slide down at a constant speed. When sliding down to the same height as the ground, there is also a button for turning off the tailboard, which is the down button. When you press this button, you have to pay attention to it. It flips down to form a small slip. This makes it easy to load and unload the goods.
