How is the Drive Shaft Working..

To know the car's drive shaft and the role of the principle, let us look at what the automotive drive shafts.

CV in a different axis between the two axes in the course of their work and even changing the relative position between the two axes passing power, connection, or assembly of parts and movable parts or rotating circular object, generally using light torsional resistance of the alloy into the control. On the front-engine rear-wheel drive vehicle is transmitted to the rotation transmission shaft final drive, which can be several sections connected by a universal joint.
According to different classification of automotive drive shafts, can be divided into open and closed, open living in the exposed environment, closed living in a closed environment. As the open shaft with the installation, repair, maintenance and convenient,
And can be widely applied.

In accordance with shaft itself is an important part - the different joints, may have different classifications. If you press the universal joint in the reverse direction if there is significant flexibility can be divided into rigid and flexible universal joint drive shaft universal joint drive shaft. The former is part of the hinged connection by passing power, the latter by the elastic components deliver power, and a buffer damping effect. Rigid joints can be divided into non-constant velocity joints (such as cross-axis joints), quasi-constant velocity joints (such as double-type universal joint, three-pin-type universal joints) and CV joints (such as the Cage-type universal joint, ball-type universal joint fork). Constant and not constant, refers to the output shaft with the shaft in rotation, in the week in terms of angular velocity is uniform, of course, driven shaft axis and the average speed is equal.

Master, slave axis angular velocity in the angle between the two axes remain the same change in the joints, known as the equiangular speed constant velocity joints or universal joints. They are mainly used for steering axle, drive axle disconnect type, de Doin type drive axle of the wheel gear, the car is mainly used in power transmission. When the car is rear-wheel drive, often with cross-axis universal joint drive shaft; when the car is front wheel drive, the constant velocity joint is often used - is a constant velocity joint drive shaft, but the title different.

At present, cross-axis gimbal shaft rigid powertrain in the car the most widely used.

Another important component of the sliding spline pair, from the inside and outside the spline form, used to pass the length changes. Swing angle shaft universal joints and sliding spline Vice maximum amount of stretching, is arranged under the vehicle when the drive shaft runout check and determined. General case may also have drive shaft tube, hollow tube with a smaller shaft can pass, but the quality of the larger torque, and the same outer diameter than the solid shaft with a higher critical speed characteristics.

Overall, the car's role is to make the shaft axis in the different between the two axes in the course of their work and even changing the relative position of power transmission between two axes,
