The reason is that the drive shaft needs to withstand torque stress and hollow settings during operation, which will increase the transmission performance and have no effect on the use of the drive shaft. The drive shaft is an important device for vehicle power transmission and exists in the vehicle chassis. If it is damaged, the vehicle cannot drive.
Since the drive shaft is a rotating body with high speed and less support, its dynamic balance is very important. The drive shaft can transmit power from the engine to the front and rear axles. For front-engine rear-wheel drive cars, the rotation of the transmission is transmitted to the shaft of the main reducer. The drive shaft can be several parts, and the sections are connected by universal joints.
1. Since the drive shaft only needs to bear torsional stress, that is, the deformation on the drive shaft is only torsion, but since the cross-section of the drive 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 drive 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 the car.
3. If you find that the drive shaft of the car is hollow, don't be nervous or surprised. These are all precisely designed, and we absolutely dare not cut corners on such important parts as the drive shaft.
What do you need to refer to for motor vehicle maintenance?
The maintenance of motor vehicles requires reference to the motor vehicle manual, the current mileage of the motor vehicle, and the use time of the motor vehicle. The motor vehicle should be maintained and effectively maintained, thereby increasing the use time of the vehicle and reducing the subsequent maintenance costs.
