The role of the drive shaft
The drive shaft 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.
The transmission shaft is an important component of the transmission power in the vehicle drive train. Its function is to transmit the power of the engine to the wheels together with the gearbox and the drive axle, so that the vehicle generates driving force.
