How does the connection structure of an automotive driveshaft assembly adapt to different transmission angles?

The connection structure of an automotive driveshaft assembly must be designed to fully consider the adaptation requirements of different transmission angles to ensure smooth and efficient power transmission. The connection structure of a driveshaft assembly mainly includes components such as universal joints, sliding forks, and flanges. The design of these components directly affects its performance under different transmission angles.

The universal joint is the core component of the driveshaft assembly, used to compensate for transmission angle deviations. Cross-type universal joints achieve angle compensation through a cross shaft and bearings, suitable for larger transmission angle deviations. Double cross-type universal joints further reduce vibration and impact caused by transmission angle deviations through the combination of two cross shafts, suitable for high-speed and high-precision transmission applications. Ball cage type universal joints achieve multi-angle compensation through the cooperation of ball cages and steel balls, suitable for complex transmission angle requirements.

The design of the sliding fork also affects the driveshaft assembly's adaptability to transmission angles. The sliding fork compensates for changes in the length of the driveshaft through axial sliding, and simultaneously achieves angle compensation in cooperation with the universal joint. The sliding fork structure must possess sufficient rigidity and wear resistance to ensure that transmission efficiency does not decrease due to wear or deformation during long-term operation.

The flange connection is a critical component connecting the driveshaft assembly to the gearbox or drive axle. The flange design must consider the impact of transmission angle deviations on connection strength and sealing. For example, some flanges employ flexible connection designs, using rubber or elastic elements to absorb vibrations and impacts caused by transmission angle deviations, improving transmission smoothness.

The overall layout and length design of the driveshaft assembly also need to be adjusted according to the transmission angle. The length and arrangement angle of the driveshaft directly affect its vibration characteristics and transmission efficiency. A reasonable length design and angle layout can reduce driveshaft vibration and noise, improving transmission efficiency and lifespan.
