Structure composition and characteristics of automobile tail plate and transmission mode

Automobile tailgate is a hydraulic drive type cargo loading and unloading equipment installed on the tail of trucks and various sealed vehicles. It can not only be used for loading and unloading cargo, but also as the tailgate of van-type trucks, so it is usually called automobile tail. board.

The operation of the tailboard is very simple. Only one person needs to control the "on" or "release" of the three electromagnets through the electrical buttons to realize the various actions of the tailboard and complete the loading and unloading of the goods, which can well meet the needs of customers. Demand was welcomed.

In addition, due to the unique design of the car loading and unloading tail plate, it is also used as a bridge plate. When the bottom of the vehicle compartment is higher or lower than the cargo platform and there is no other loading and unloading equipment, the tail end of the load-bearing platform can be placed on the cargo platform to form a unique "bridge", and the cargo can be completed in time with a manual forklift. Loading and unloading. This is crucial.

Structural characteristics of five-cylinder drive tail plate

1. Structure composition

The tail plate is composed of: bearing platform, transmission mechanism (including lifting cylinder, closing cylinder, pressurized cylinder, square steel support, lifting arm, etc.), bumper, pipeline system, electronic control system (including fixed electric control box and Wire controller), oil source (including motor, oil pump, various hydraulic control valves, oil tank, etc.).

2. Unique features

Since the load-bearing platform is a wedge-shaped structure, after it is horizontally landed, a head-down motion is required to make the tip of the board land on the ground to facilitate the loading and lowering of the load-bearing platform by hand-push (pull) equipment such as manual forklifts. There are currently four types of low (lifting) tailboards commonly used, and the tailboard structures produced by different manufacturers are different.

3. Transmission mode

The equipment adopts the transmission method of using the car battery as the power source and the DC motor to transmit the load. The DC motor drives the high-pressure oil pump, and then the solenoid valve controls the movement of the hydraulic cylinder to drive the four-bar linkage mechanism to move the load. The platform completes various actions such as ascending, descending, and opening and closing the door.

4. Security agency

Since the tailgate of a car is a device that is installed at the rear of the vehicle and moves with the vehicle, in order to ensure driving safety and protection equipment, warning devices and safety devices are required. The tailboard is not only equipped with safety flags and reflective warnings on the back of the bearing platform Plate, anti-skid safety chain. To

When the loading platform is in a horizontal position, it is only in a line when viewed from a place 50m away, which is very difficult to find. When the vehicle behind is driving at a speed of 80km per hour, accidents are prone to occur. After the safety flag is installed, the flag hangs down to a right angle to the load-bearing platform by its own gravity. Two safety flags can be seen from a distance, which provides a warning to prevent the subsequent vehicle rear-end collision accident. Played a big role. To

The function of the reflective warning panel is: the reflective panels installed on both sides of the back of the load-bearing platform have reflective functions, especially when driving at night. After being illuminated by the lights, they will be found far in the front, which not only protects the equipment, but also prevents Later, the occurrence of rear-end collisions of vehicles played a certain role. To

During the driving of the vehicle, it is possible that the load-bearing platform may slide down due to the leakage of the oil cylinder or the burst of the oil pipe. The existence of anti-skid safety chains prevents this phenomenon from happening.
