There are a lot of Porsche car owners out there who tend to be confused with the different parts found in the various systems that run their cars. Among the most common words, you can use interchangeably are the Porsche shaft and Porsche axle. How different are these two components from each other?
Functions of the Shaft and Axle
One way by which we can differentiate the shaft from the axle is through their functions. The shaft plays a critical role when it comes to transmitting power from one part of the vehicle to another. This part is generally used in applications for shear and torsion stress. It is responsible for specifically transmitting rotation and torque from the drive train to those of other components.
What about the axle? The axle is actually a shaft that is used for rotating wheels. It has been designed in order to take bending loads coming from the wheels or any other rotating parts with which it is used. The axle is often static by nature but there are some car models where the axle rotates with the wheels.
Shaft and Axle Dynamics
You have to take note that the difference between axles and shafts will depend upon their dynamics. Axles are referred to as static rods that are capable of supporting rotating parts while shafts are responsible for enabling motion and transmitting motion. Acting as a wheel support, axles work even if they do not transmit motion and power. Shafts, on the other hand, accept power and can drive gears, sprockets, pulleys, and other elements of rotary power.
Axles and shafts are both capable of carrying heavy loads and can rotate easily even with incredible speed. Sometimes, however, shafts can become ductile which will lead to their deflection and misalignment as well as compromise bearings.
Bearings and How They Support Shafts
Bearings are crucial factors that dictate shaft behavior. They allow the shaft to pivot under circumstances where there is a transverse load. There will come a time when radial end movement can be prohibited thus forcing the shaft to flex and eventually raises the vehicle's critical speed.
Taking Care of Shafts and Axles
Speed can compromise the functionalities of both shafts and axles. This will mean further complications on how the car will operate. As speed increases, vibration occurs which can compromise shafts and axles. It can be a cause for accidents when not attended to immediately. It is therefore crucial to make sure that these parts are taken care of. They should be checked every once in a while especially when you are sending out your Porsche for service. Apart from speed, torsional resistance must be avoided because this can result in torque disturbances and fluctuations.
Both axles and shafts are critical components of the car. Whether one acts as a carrier of the load and the other causing the wheel to turn, these two have to be given the much attention that they need at all times. You cannot just pay attention to the axle and shoo away the needs of the shaft. Both have to be functioning properly to keep you safe down the road.
