Precautions for the use of automobile universal joint drive shaft

The universal joint drive shaft of a car is made up of two main components, a drive shaft and a universal joint. It can be said that the universal joint and the drive shaft are complementary to each other. The universal joint drive shaft is mainly used to transmit torque and rotational motion between two shafts whose relative positions are constantly changing during the working process. With the rapid development of the automobile industry, the diversification and individualization of vehicle models has become a development trend, and the requirements for energy saving, comfort and light weight of automobiles are getting higher and higher. The improper design and assembly of the drive shaft and the universal joint will produce vibration and noise, increase the unexpected dynamic load, and may also cause the transmission system to fail to operate normally and early damage. Therefore, the universal joint’s drive shaft The choice is also a test of the performance of the car. The design of the universal joint is also very important to the car. You must pay special attention when using the drive shaft. Improper use, excessive use, etc. may lead to the universal joint transmission. If the shaft fails or is scrapped, let's take a look at the precautions.

1. When the car starts, lift the clutch to avoid excessive force, and the throttle should not be too large, otherwise it is easy to cause the universal joint drive shaft to break.
2. There are certain requirements for the passability of the car. When passing the road with poor road conditions, prevent foreign objects from colliding with the universal joint drive shaft, otherwise it will cause accidental damage such as shaft tube deformation.
3. When the intermediate support is damaged, first check whether the support is not filled with grease on time, then check whether the shaft tube is twisted and deformed, and finally check whether the support fixing frame is adjusted to make the support in an abnormal stress state.
4. Special universal joint drive shafts must be customized for model modification and transmission system changes, otherwise it will easily cause vehicle vibration, affect the normal service life of the drive shaft, and even cause vehicle accidents.
5. During driving, if there is abnormal noise or vibration of the universal joint drive shaft, stop and check immediately, and promptly check and repair the nearest service station or ask professional maintenance personnel to check and repair, and do not let the sick car go on the road.
6. When transporting the universal joint drive shaft, do not operate it brutally, and pay attention to handle it gently to prevent damage to the dynamic balance due to bumps, which may cause abnormal vibration.

All parts of a car need to be well maintained. Any small part may be related to the service life of the car. If you want to use a car well, you must treat every part of the car well.
