Automotive drive shaft introduction
The drive shaft is a shaft that transmits power in the drive shaft of the universal joint. It is a high-speed, low-supporting rotating body, so its dynamic balance is crucial. Generally, the drive shaft must be tested for dynamic balance before leaving the factory and adjusted on the balancer. For the front-engine rear-wheel drive car, the rotation of the transmission is transmitted to the main reducer shaft, which can be several sections, and the joints can be connected by a universal joint.
