Forklift wheel hub and forklift wheel rim circular rim are drive axle components with completely different structural shapes, application performance, and functions. They are often confused in daily life, and it is not uncommon to mistake the forklift wheel rim steel rim for the wheel hub. The wheel hub is a thin-walled rotating accessory in the shape of a cylindrical barrel, installed and connected to the drive axle housing shaft head through fixed bolts and half shafts. The material is generally ductile iron, and the wheel rim, also known as the steel rim, is in direct contact with the tire. The open type forklift wheel rim locking ring type actually includes the wheel rim retaining ring, The material process is divided into casting and welding processing, used for installing and supporting tires. The outer ring of the wheel hub and the wheel rim are connected by bolts. The forklift axle body is divided into front axle (drive axle) and rear axle (steering axle), corresponding to the drive wheel hub and steering wheel hub, respectively. The structure and connection method of the two are different. One end of the front wheel drive wheel hub is rigidly connected to the half shaft flange with bolts, and the torque transmitted by the half shaft drives the wheel rim and tire to rotate through the wheel hub. The other end of the driving wheel hub is connected to the wheel hub and brake hub with bolts, while achieving the braking effect of the front wheels. The inner bearing of the driving wheel hub allows the front wheels to rotate on the drive axle housing, while the rear wheel steering wheel hub is installed on the steering knuckle shaft end through the bearing, and the limit is fixed by two inner and outer bearings. The flange of the rear wheel steering wheel hub is connected to the wheel rim.The bearing seat holes inside and outside the wheel hub, as well as the oil seal seat holes, are prone to wear. Regular inspection, lubrication, and maintenance can help extend the service life of the drive wheel hub The drive axle mainly consists of the drive axle housing, drive wheel hub, half shaft, brake drum, brake, etc. The drive axle of a 5-10 ton forklift is different from that of a small tonnage forklift, and also includes a wheel reducer assembly. The overall casting structure of the drive axle housing of the 3-ton series forklift is equipped with shaft machining at both ends. The power transmission method is differential half shaft drive wheel hub wheel hub tire. The drive axle housing of the 5-10 ton series forklift is made of cast steel structure, and the fan-shaped plate at the front end of the drive axle housing is connected to the forklift main frame bolt. The power transmission method is main reducer half shaft wheel reducer drive wheel hub tire. Therefore, there are certain differences in the drive wheel hub structure of forklifts of different tonnages, but the working principle is the same

As one of the core components of the front axle drive transmission system, the forklift drive wheel hub often experiences natural wear and abnormal problems during the continuous transmission of driving torque. Due to improper adjustment or insufficient lubrication, the tapered roller bearings inside the drive wheel hub are easily damaged, the inner and outer bearing seat holes of the wheel hub are worn, the oil seal seat holes are unevenly worn, the internal oil seal of the drive wheel hub is aging and leaking oil, the fixing bolts between the drive wheel hub and the brake wheel hub are loose, resulting in uneven friction on the plane and poor contact, the threads inside the fixing half shaft bolt holes of the drive wheel hub are damaged, and the concentricity of the end face in contact with the half shaft edge is a common fault in the use of the drive wheel hub. Within the repairable range of wear, it can be treated by welding and turning to regenerate the parts after use. Due to the design of the wheel hub torque transmission Requirement, High machining accuracy is required. The selection of brake hubs with qualified machining accuracy and quality directly affects the rotational stability and torque transmission efficiency of the combination with the drive hub. Front axle troubleshooting includes the replacement of brake drums and half shafts. It is recommended to check the wear status of the drive hub, tapered roller bearings, and internal lubrication maintenance to improve service life The specifications and models of the drive wheel hub are basically divided into the 3-ton series and several commonly used series such as 5-ton and 10 ton. Different forms of drive axles (half axle axles or side reduction axles) and load-bearing capacity are used for selection. The high fitting accuracy of the drive front axle transmission system components can improve torque transmission efficiency and reduce energy consumption. When replacing or repairing the half axle, brake drum, tapered roller bearings, etc. before use, it is necessary to confirm concentricity and strictly follow the installation process. The drive axle needs to be stopped in a timely manner for high temperature heating, oil leakage, abnormal noise during driving, especially continuous noise, which needs to be dismantled and thoroughly inspected
