HOWO heavy truck universal joint WG9319313250

Description

SINOTRUK HOWO heavy truck universal joint WG9319313250:

In the complex transmission system of heavy trucks, the universal joint WG9319313250 is undoubtedly the core component. It is mainly applied in the drive axle and steering system of heavy trucks to achieve the transmission of motion between different axes. The performance of this universal joint directly affects the overall operation of the truck.

The main functions of the universal joint WG9319313250 are as follows:

1. Angle transmission: It is mainly used to connect transmission shafts with different axis lines, enabling the transmission of power between two shafts while accommodating the angle changes and relative displacements between the two shafts. For example, in the transmission system of an automobile, it can transfer the power from the transmission output to the drive axle. Even when the transmission shafts’ angles change due to the movement of the suspension system during vehicle driving, the universal joint cross shaft can ensure the effective transmission of power.
2. Buffering and shock absorption: During power transmission, the universal joint cross shaft can play a certain role in buffering and shock absorption, reducing vibrations and noises caused by factors such as engine vibration, uneven road surfaces, and shock from the transmission system, thereby improving the smoothness and comfort of vehicle driving.

Structure of the universal joint WG9319313250:

1. The main body of the cross shaft, the cross shaft is the core component of the universal joint, mainly forged from high-quality alloy, with high strength and toughness. The four shaft diameters are perpendicular to each other, and needle roller bearings are installed on them.
2. Needle roller bearings, the number of needle rollers in the needle roller bearings is large and the diameters are small. The contact area with the shaft diameters is large, which can evenly distribute the load transmitted by the transmission shaft, effectively reducing the pressure per unit area. During operation, the needles can roll flexibly between the inner and outer rings of the bearing, greatly reducing friction resistance and improving transmission efficiency.
3. Universal joint fork, the universal joint fork is closely connected to the cross shaft through high-strength bolts. Its design fully considers the requirements of heavy truck power transmission. The shape and size of the fork opening of the universal joint fork have been precisely calculated and optimized, which can achieve precise cooperation with the cross shaft, ensuring the accuracy and reliability of power transmission. At the same time, as an important interface connecting transmission shafts, drive bridges and other components, the strength and rigidity of the universal joint fork have also been strictly tested. Under the condition of bearing huge torque and complex stress, it can still maintain a stable connection state, avoiding the influence on power transmission due to loosening or deformation.

Common faults of universal joint WG9319313250:

1. Wear and tear. Over time, the wear of the shaft diameter and needle roller bearings will lead to a decrease in transmission efficiency, generating noise and vibration.
2. Cracks. Due to prolonged exposure to high impact forces, the cross shaft may break. This could be a material issue or caused by overloading of the vehicle.
3. Stalling. Caused by foreign objects in the needle roller bearing oil or insufficient lubrication, it affects the normal power transmission.

How to maintain and service the u joint?

1. Regular lubrication: Add lubricating grease to the cross shaft of the universal joint at regular intervals to reduce friction and wear.
2. Check the wear condition of the needle rollers. If any wear, cracks or other damages are found, replace them in time.
3. Cleanliness: Keep the cross shaft of the universal joint clean to avoid wear caused by excessive impurities.
