Iron shoulder 188 high-end loader, each component (engine, air filter, muffler, water tank, torque converter, drive shaft, axle, oil cylinder, pin shaft, oil pipe, wire alignment, steering gear, priority valve, pump valve, fuel tank) advantages are as follows:
The pipe wall of the muffler is thickened, the insulation cotton is outsourced, and the professional bracket of 8mm bent steel plate is used to reduce vibration. The interior of the muffler is changed to a three-chamber expansion chamber, with a symmetrical structure, which can suppress the vibration of the airflow very well, and requires a good noise reduction effect. The muffler is built-in, improving the appearance. Hangers are led out from both sides of the undercarriage, and the design of this hanger avoids the wear of the rear hood during the lifting process.
The export standard torque converter is adopted, and the overall quality is improved. The friction plate of the torque converter is upgraded from asbestos to copper, and the internal transmission gears and bearings are all quenched and tempered. The imported oil seal complies with the national standard GBT25627-2010 for engineering torque converters.
The national standard transmission shaft is adopted, and all of them have passed the dynamic balance test. The universal joint bearing complies with ZBJ11014 regulations; the universal joint cross shaft is produced according to JB524 standard. The front drive shaft adopts a bridge design, and the bridge is located at the midpoint of the drive shaft to prolong the service life.
The thickened cast axle housing has a stronger load-bearing capacity and complies with the national standard GB5333-1985 for driving axles. . The internal bearings, gears, and ring gears are made of 20 chrome, and the gears are made of fine grinding technology and high-frequency quenching treatment, which increases the strength and wear resistance by 3 times. The oil seal uses imported materials. The half shaft is processed by quenching and tempering process, Luoyang bearing, the sleeve is made of 40 chrome material, the strength is higher after quenching and tempering process, the brake caliper piston column is chrome-plated, the brake disc is thickened (12MM), and the first warranty time of the drive axle is 250 hours.
The piston rod of the oil cylinder is plated with more than 3 wires of hard chrome after modulation, which is 3 times higher than that of ordinary pistons with 1 wire of chrome. The piston and guide sleeve are made of ductile iron. The oil seal uses high-quality polytetrafluoroethylene oil seal. After the cylinder is welded, it has undergone secondary correction processing to prevent the internal leakage power loss caused by the deformation of the cylinder caused by welding.
