Problems solved by technology

However, when the existing forklift is carrying goods, the position of the goods on the forklift will change, resulting in a different center of gravity of the forklift. The further the center of gravity moves back, the greater the pressure on the rear driving wheels, which is easy to cause damage to the forklift. and dump

Embodiment 1

[0054] Embodiment 1, have the forklift that can automatically adjust the balance wheel load suspension system, such as Figure 1-5 As shown, it includes a support leg 1, a door frame 3, an elastic device 5, a fixed plate 4, an auxiliary support assembly 7, a rear driving wheel 9, and an oil storage device 10.

[0055] The number of supporting legs 1 is two, and the two supporting legs 1 are arranged parallel to each other, and the head end of the supporting legs 1 is rotated to be provided with a front driven wheel 2 .

[0056] The door frame 3, the fixed plate 4 and the rear driving wheel 9 are arranged in sequence along the direction from the head end to the tail end of the support leg 1.

[0057] The door frame 3 is slidably arranged on the support leg 1; the door frame 3 can slide back and forth along the length direction of the support leg 1.

[0058] The door frame 3 comprises a horizontal plate 31 arranged horizontally and a vertical plate 32 arranged vertically, the t...

Embodiment 2

[0088] Embodiment 2, have the forklift that can automatically adjust the balance wheel load suspension system;

[0089] Replace the elastic device 5 in Example 1 with buffer structures such as rubber pads, cylinders, composite springs or air springs, as long as it can ensure that the guide sleeve 12 and the piston rod 15 are reset after the cargo is unloaded.

[0090] The oil in the piston cylinder 16 and cylinder barrel 19 in Embodiment 1 is replaced with other substances such as compressed gas.

Abstract

The invention provides a forklift with a suspension system capable of automatically adjusting a balance wheel load. The forklift comprises supporting legs, a door frame, an elastic device, a fixing plate, an auxiliary supporting assembly and a rear driving wheel. Front driven wheels are rotationally arranged at the head ends of the supporting legs; the portal, the fixing plate and the rear driving wheel are sequentially arranged in the direction from the head end to the tail end of the supporting leg. The portal frame comprises a horizontally arranged transverse plate and a vertically arranged vertical plate, and the tail end of the transverse plate is fixedly connected with the bottom of the vertical plate; the transverse plate is arranged on the supporting legs in a sliding manner; according to the forklift with the suspension system capable of automatically adjusting the balance wheel load, the auxiliary balance wheel can share the pressure borne by the rear driving wheel, so that the pressure borne by the rear driving wheel is kept constant as much as possible. The invention is safer and does not cause excessive burden to the rear driving wheel.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a forklift with an automatically adjustable balance wheel load suspension system and a use method. Background technique [0002] Forklifts are used for transportation, which can greatly reduce labor and operating costs. It is applied to the distribution of materials in the workshop, reducing the number of workers in the workshop aisle, creating a green chemical factory, and stacking in the factory warehouse, making the storage more standardized and orderly, and fully improving space utilization and transportation efficiency. . However, when the existing forklift is carrying goods, the position of the goods on the forklift will change, resulting in a different center of gravity of the forklift. The further the center of gravity moves back, the greater the pressure on the rear driving wheels, which is easy to cause damage to the forklift. and dumping occurs. [0003] Therefore,...
