The main purpose of making the transmission shaft hollow

The reason is that the transmission shaft needs to bear the torque stress and the hollow setting in the working process, which will increase the transmission performance and have no effect on the use of the transmission shaft. The transmission shaft is an important device for vehicle power transmission, which exists in the chassis of the vehicle, and the vehicle cannot run after being damaged.

Since the transmission shaft is a rotating body with high speed and few supports, its dynamic balance is very important. The drive shaft transmits power from the engine to the front and rear axles. For cars with front-engine rear-wheel drive, the transmission's rotation is transferred to the shaft of the final drive. The transmission shaft can be several parts, and the joints are connected by universal joints.

1. Since the transmission shaft only needs to bear torsional stress, that is to say, the deformation on the transmission shaft is only torsion, but since the cross section of the transmission shaft is a circle, when subjected to torsional stress, the stress farthest from the center of the circle is the largest;

2. The stress at the center of the circle is 0, and the transmission shaft is hollow, which has no effect on the work. At the same time, it can save materials and costs, and is also conducive to the lightweight of automobiles.

3. If you find that the drive shaft of the car is hollow, don't be nervous or surprised. These are precisely engineered, and there is absolutely no daring to cut corners on such an important component as the drive shaft.

What does motor vehicle maintenance need to refer to?

The maintenance of motor vehicles needs to refer to the manual of the motor vehicle, the current mileage of the motor vehicle, and the use time of the motor vehicle to maintain the motor vehicle and effectively maintain the motor vehicle, thereby increasing the use time of the vehicle and reducing the maintenance cost in the later period .
