It is noted Chengguan Forklift forklift parts, forklift repair techniques on normal terms, forklifts powered by internal combustion forklifts and electric forklifts divided. Internal combustion engine-powered forklifts with its strong power, wide application, the disadvantage is greater emissions and noise pollution, harmful to human health. To improve product energy efficiency and meet increasingly stringent environmental requirements, the main consideration of manpower from the lower engine emissions and improve the efficiency of hydraulic systems and vibration, noise and so on. To be sure, less emissions, less noise forklift certainly be welcome. Battery forklift, natural gas, liquefied petroleum gas and other fuel truck will certainly get further development.
Truck driving, drive cross bearing is subjected to a lot of torque and impact loads, while for the high-speed rotation, with constant vibration, poor lubrication conditions, and therefore prone to wear, deformation and damage, and thus malfunction, there will be different loud and chattering fault. Truck started, if the body shivering, accompanied by "friends grid lattice friends." Crash; driving can still hear the sound of the chassis there is a cyclical, faster, louder. Serious, cab vibration, hold the steering wheel, hand numbness. The reasons are: universal joint cross shaft and wear Songkuang needle or needle broken off; each connector screws loose parts. Shaft bending deformation. When you encounter this failure, check the connections to the vehicle loose screws, and hand shaking shaft, can detect the wear parts; the rear set up, hanging file rotation, check the drive shaft vibration and abnormal sound impressive case ; also may drive shaft with a dial indicator to detect the amount of deformation, then identify the reasons were to be repaired.
Once the shaft assembly balancing state destroyed, will be affected by additional dynamic loads caused by the centrifugal force at work, easy to produce bending deformation, vibration and noise caused by the drive shaft, increasing the dynamic load, transmission efficiency decreases, accelerating damage to the part. Use the shaft accidental impact, percussion deformation, surfacing after the destruction of parts to each other so when the disassembly position accuracy, both allow rotating shaft assembly of the center of mass of the rotational axis deviation, destroying its balance.
When conservation, want to cross bearing lubrication; checking whether the cross bearing Songkuang when the transmission in neutral hanging, release the parking brake, hands clasped shaft axis tube, turning sharply around hard, there should be clear The rattling of the amount necessary to remove the decomposed repair. Also check whether the shaft is fixed firmly conservation fasteners, shaft bending appearance and, if necessary, repaired.
It is understood Chengguan Forklift forklift parts, repair front driveshaft assembly, shall be cleaned of its various components, particularly oil channel cross shaft journal and needle roller bearings, etc., should be washed clean with kerosene and dried with compressed air . Mating surfaces coated with grease, after co-mark refitted. After gimbal refitted, there is no significant gap should be flexible rotation, the phenomenon can not have hairpin.
Forklift Mast Mast two basic types of internal and external door frame arrangement in the form of overlapping, parallel and integrated, external door frame with slotted uprights generally used to suppress and welded steel. Set up the outer door leading role in the movement of the door frame, its two parallel columns of the beam, the beam and the floor firmly welded together.
