The Difference Between Two-piece Driveshaft and Four-piece Driveshaft

The difference between two-piece driveshaft and four-piece driveshaft is the level of manual angle that is incorporated into the drive shaft itself. When it comes to the construction of a two-piece driveshaft, there is no need to make use of the conventional casting method because the frame can simply be molded using any plastic resin material and then the shaft can be bolted directly onto the frame. In the case of four-piece driveshaft, a two piece shaft is used but with the added factor of a pinion or rack angle at the point where the shaft joins the frame.

In general two-piece driveshaft consists of a bracket that contains the pins or rings and the carrier bearing, which is positioned directly below the bracket. The carrier bearing is placed in a u-joint that is designed to accept bolts of varying sizes. The pins of the bracket are inserted into the u-joint through bolts that are of varying sizes. Once the pins are inserted, they are brought into contact with a series of springs that enable the bearing to tilt its mounting pins. Once the pins are locked, the spring is released and the pinion and rack move up and down creating the torque necessary to operate the driven unit. As you can see, the overall process is very similar to that of a traditional screw carrier but instead of using a screw, there is a pin that is able to absorb torque when a load is applied on it.

The benefit of this construction is an increased efficiency when it comes to the transmission of power through the engine. The increase in efficiency also increases the reliability of the two-piece driveshaft as there is a greatly reduced risk of a carrier bearing failure due to thermal breakage, groove wear, or general lubricant build up. In addition to this, there is increased security when it comes to the transportation of sensitive, expensive and in some cases sensitive components. If an incident were to occur, the transmission could easily be disabled until the proper carriers or bearings could be found. Therefore, safety is an important issue that must be addressed when it comes to selecting and installing a two-piece driveshaft.

In the recent past, many manufacturers of two-piece driveshaft have chosen to incorporate a one-piece design that was built upon a steel plate. This type of construction would certainly have merit, however, the cost savings associated with incorporating a one-piece construction is a clear consideration when it comes to choosing a two-piece driveshaft. This decision does not necessarily mean that you are limited to standard steel plates, however. In fact, there are several options available to you when it comes to finding a carrier bearing to meet your specific needs.

For instance, two piece driveshaft that uses a shaft with a driveline can often be constructed using standard tubing. The benefits of selecting a driveline for your two-piece driveshaft is the elimination of most of the weight attributed to the shaft. In addition, it increases the surface area of the drive shaft which improves both power and maneuverability. Additionally, there is increased security when it comes to the transportation of sensitive, expensive and in some cases dangerous components.

A two piece driveshaft can also be constructed using steel tubes. However, these tubes are typically wider and offer greater stability than their two piece counterparts. The benefit of selecting this option is the elimination of an additional weight category that is placed on the vehicle. Additionally, the use of tubes provides increased load security for the entire assembly while also reducing the potential for damage due to vibration and creep. One can only imagine how much safer two piece driveshaft made from these types of tubes would be for trucks and other large vehicles.

The construction of a two-piece driveshaft is not complete without the addition of the u-joints and the dana-spicer. U-joints are used as a means of securing the two shafts of the driveshaft together. They are typically made of either cast iron or high quality steel. Some u-joints are actually spring loaded, which allows them to remain rigid during operation. These units are available in both single and dual mode, which is great for applications requiring flexibility. Furthermore, the new u-joints and dana-spicer are typically designed to minimize any contact time with the bottom of the shaft which, in turn, will decrease the risk of damage or injury to the operator.

In summary, the most important component of a two-piece driveshaft is its pinion and transfer case output. Both of these important components should be designed to work in conjunction with each other in order to provide the best possible performance. Additionally, the overall design of the driveshaft, the quality of its components, and its effectiveness in resisting and containing damage are three other factors to consider when shopping for a two-piece driveshaft.
