Forklift parts knowledge about gearbox
1. The role of the forklift gearbox Because the engine can not be reversed, the forward and reverse movement of the forklift is also solved by the transmission. The main function of the gearbox is to adapt to the high-speed driving of the vehicle under various road conditions, speeding up the climb and flattening. The gearbox changes the torque and speed of the engine output to suit the driving requirements. In addition, the gearbox can also separate the engine's operation and drive system from each other for a longer period of time.
2. When the forklift gearbox is used for gear shifting or shifting gears, the accelerator pedal (throttle) should be released. After the oil is collected, press the clutch pedal to quickly push or pull the gear to be hung. Release the clutch. Do not push or pull hard when shifting gears, so that the gears will make a shock.
3. Hydraulic torque converter, gearbox (1) The hydraulic transmission gearbox used in the 1.5T-3T forklift is composed of a torque converter and a power shift transmission with one gear position in front and rear. The installed torque converter is a single-stage two-phase three-wheel integrated hydraulic torque converter. The torque converter makes the hydraulic transmission gearbox have the automatic adaptability of the hydraulic transmission output, can change its output torque and rotation speed correspondingly with the change of the external load, and can absorb and eliminate the transmission from the engine and the external load. Shock vibration brought by the system. The hydraulic transmission gearbox is output as a differential half shaft gear. The shifting mode adopted is power shifting with a micro-motion valve and a buffer valve, which makes the operation simple, convenient, and stable, and greatly reduces the labor intensity of the operator.
(2) Hydraulic transmission gearbox used in 5T~6T forklift is a single-stage three-phase four-wheel integrated hydraulic torque converter with large torque ratio, high efficiency, wide range of efficiency and simple structure. , easy to maintain features. It has two gears, forward and reverse, which are soft and stable in operation and have micro-motion characteristics.
4, forklift gearbox maintenance needs (1) in order to ensure the hydraulic control of the mechanical parts of the oil circuit and the life of the sealing components, control the normal pressure of the oil circuit 1.1 / u1.4Mpa
(2) Working oil is 20# turbine oil (or 6# hydraulic transmission oil), turbine oil, using oil temperature 70-95~C, the use time is not too long after more than 95cC.
(3) The replacement and cleaning cycle of the oil filter, the new car is within 50h, and every 200h, 1200h, the special environment should be every 600h.
(3) When the forklift is driving and shifting gears, first close the micro-motion valve and then shift the gear; when braking, you must first close the micro-motion valve and then brake; to prevent the clutch from being damaged or the brake is not working.
Hefei forklift gearbox input gear heat treatment process improves the forklift input gear as a key component of the forklift drive system, and has strict requirements on surface hardness, wear resistance, overall strength, and core toughness. The user's feedback indicates that the main failure modes of the gearbox are gear tooth surface wear, pitting, spline tooth surface wear, etc., and occasional fracture failure occurs at the output journal, although such parts only account for gearbox parts. 1/4 of the total, but they have a great impact on the transmission of power and motion. If one of the parts fails, the transmission system will be functionally replaced. The wear resistance and wear life of the transmission parts are mainly addressed. The strength reliability of the part. Based on the actual production of the company, through careful analysis and research on the performance requirements of the input gear of the forklift gearbox, a reasonable and effective heat treatment process is taken to ensure its quality, and the material selection, surface carburizing and related heat treatment processes are more reasonable and feasible. Improvement measures.
