1.Connection and Support Role
a. Connection Drive Shaft: Truck center bearing is located in the middle part of the drive shaft, play a role in connecting the two sections of the drive shaft. In the long wheelbase truck, due to the long length of the drive shaft, the center bearing is needed to ensure the integrity and stability of the drive shaft. For example, when the truck is running, the engine power is transferred to the drive shaft through the transmission, the center bearing ensures smooth power transfer between the two sections of the drive shaft.
b. Support Drive Shaft: Bear the weight of the drive shaft and the rotation of various forces, including radial and axial forces. It enables the driveshaft to rotate stably at a certain position to ensure the reliability of power transmission during truck driving. For example, when the truck is fully loaded with goods driving on the rugged road, the center bearing can withstand the impact and vibration from the road surface to ensure that the drive shaft will not be damaged due to uneven force.
2.Reduce Vibration and Noise
a. Absorb Vibration: Trucks will be affected by uneven road surface, engine vibration and other factors in the process of driving, resulting in vibration. The center bearing can absorb part of the vibration, reduce the vibration transmission to other parts, improve driving comfort and vehicle stability. For example, when the truck passes through the bumpy road, the center bearing can reduce the vibration amplitude of the drive shaft through its own elasticity and damping characteristics.
b. Noise Reduction: Since the center bearing can reduce the vibration of the drive shaft, it also reduces the noise generated by the vibration. This is very important to improve the truck's NVH (Noise, Vibration, Harshness) performance, so that drivers and passengers in the vehicle can enjoy a relatively quiet environment.
3.To Ensure The Smoothness Of Power Transmission Role
a. Ensure Rotational Accuracy: The high-precision design of the center bearing can ensure the rotational accuracy of the drive shaft and make the power transmission smoother. If the center bearing is worn or damaged, it will lead to unstable rotation of the drive shaft, affecting the efficiency of power transmission, and may even cause vehicle failure. For example, in high-speed trucks, the good performance of the center bearing can ensure that the driveshaft rotates at a stable speed, ensuring the continuity of power output.
b. Adapt To Different Working Conditions: trucks driving in different road conditions and load conditions, the center bearing needs to be able to adapt to these changes, always maintain a good working condition. For example, in climbing, accelerating, decelerating and other different working conditions, the center bearing can withstand the corresponding force and torque to ensure the normal operation of the drive shaft.
