Description

Technical Field

[0002] The braking system is an important part of the forklift and plays a vital role in the driving safety of the vehicle. The driving safety of the hydraulic forklift depends largely on the reliability of the braking device. A good braking device can ensure that the hydraulic forklift can travel at a stable speed and can also ensure that the hydraulic forklift can fork goods smoothly, improve driving comfort, and thus improve the productivity of the hydraulic forklift.

[0003] A hydraulic forklift usually includes an inching pedal, a brake pedal, and a brake pump. When the inching pedal is pressed, the valve stem moves, reducing the pressure in the torque converter, thereby cutting off the output power of the gearbox. The inching pedal can also realize the inching function. When the brake pedal is pressed, the brake mechanism is linked to brake the forklift. At present, forklifts are usually set to control the inching operation with the left pedal and the braking with the right pedal. With this structure, the lever ratio of the connecting rod mechanism between the inching pedal and the gearbox is fixed, and the inching sensitivity cannot be adjusted, which affects the operating comfort. In addition, many drivers will directly start and trigger the vehicle to move when the gear is engaged at idle, which is unsafe and does not meet the CE certification requirements.
