Drive shaft types
Dec 21, 2018

There are many types of drive shafts, which can be classified according to their unique key components, the universal joints. If the universal joint has obvious elasticity in the direction of twisting, it can be divided into a rigid universal joint drive shaft and a flexible universal joint drive shaft. The former relies on the hinged connection of the parts to transmit power, while the latter relies on elastic parts to transmit power and has a buffer damping effect.

 

The rigid universal joint can be further divided into a non-uniform universal joint, a quasi-constant speed joint and a constant velocity joint. The constant speed and the non-equal speed refer to whether the rotational angular rates of the driven shaft are equal when the driven shaft rotates. Of course, the average rotational speeds of the driving shaft and the driven shaft are equal.

 

The angular velocity of the main and driven axes is still equal when the angle between the two axes changes, and is called a constant velocity joint or an equal angular joint. They are mainly used in wheel transmissions for steering axles, disconnected drive axles, etc., and are mainly used for power transmission in cars. When the car is driven by the rear wheel, the cross-shaft universal joint drive shaft is often used. For some high-end cars, the same speed ball head is also used. When the car is driven by the front wheel, the constant velocity joint is often used. www.morayshaft.com
