ECN3-4000-AA
The driveshaft universal joint (technical name: Universal Joint Cross Shaft) is a key component in the automotive transmission system. Its core function is to achieve‌variable-angle power transmission‌, ensuring stable power transfer between the driveshaft, transmission, rear axle, and other components‌. During vehicle operation, the transmission and rear axle experience relative displacement due to bumps or steering, the universal joint allows adjacent shafts to pivot within a range of‌15°~20°‌, ensuring continuous power transmission‌. Its cross-pin hinge structure absorbs vibrations from the transmission system, protecting other components from impact‌. Some models come with grease fittings and require regular lubrication to reduce wear‌. If the universal joint is damaged, it may cause abnormal noises, power transmission interruption, etc., requiring timely maintenance or replacement‌.
