Automotive Universal Joint

Universal joints, otherwise known as U-Joints, are bendable mechanical devices used to connect two shafts which are not aligned with one another. Through this connection, the rotational movement of one shaft can be transferred to the other shaft. For an example in automotive use, a Universal Joint may be used to in a vehicle’s transmission system, where the driveshaft is connected to the axle using such a device.

The origin of the Universal Joint can be traced through the centuries, with the general idea sprouting from the design of the Gimbal. A probable use of U-Joints was in the mechanism of ballistae, a weapon used by the Ancient Greeks, although the first known reference of the Universal Joint came from an Italian mathematician known as Gerolamo Cardano, in 1545. But it is still uncertain whether he was able to construct a working prototype of this device.

A Universal Joint has a striking significance to a plus sign in appearance; containing a shimmering circular head on each of its four ends. The construction of this device is such that it contains a set of hinges that are positioned near one another, angled at 90° and are linked by a cross shaft. The caps of a U-Joint are firmly attached, sealed; after which grease is applied to the interior to extend the lifespan. They may require a significant amount of strength and force to remove detach them. The usual method followed to remove the joint is where a socket is put on top of the cap and is struck repeatedly so as to prevent any extensive damage to the connectors.

After years of use, a Universal Joint will slowly deteriorate and will require a replacement. The process is made faster if the vehicle in concern goes through rough terrain containing dirt, mud, etc. As numerous debris starts to infiltrate the interior of the U-Joint, it will eventually fail. To prevent a quick loss of your Universal Joint, a regular maintenance routine should be followed where it is checked for damage and smeared with grease.

You can get Universal Joints in two different styles: either solid or bored, with a few more variant classes in the bored style itself. As suggested by the name, solid hub joints are made to be solid. No form of work has been done on them before sale, which implies that the customer himself will have to apply the modifications necessary for the solid hub universal joint to work on his vehicle. As with the bored style, they come in different shapes: squared, hexagonal or circular, and they are called according to the shape of their hole.

A high-grade Universal Joint will provide years of unfaltering quality performance if they are maintained appropriately. For vehicles that may encounter a large amount of dirt, mud or grime such as four-wheel drive vehicles, a suggestion is to attach a greasable U-Joint so that it does not die out early in its lifecycle. There are vast numbers of different U-Joints available differing in both quality and price, and it is never a good idea to get a cheaper U-Joint simply to save some money. Such a hasty and unconsidered decision may lead to large repair bills; with a smart, thought-out decision of buying a high-grade component is what will save you money. Not to mention all the harassment encountered during vehicle repair.

Although the Universal Joint is not designed to perform any movement on its own, it is still a vital piece of equipment that is needed in every automotive vehicle and numerous other heavy machineries. It is what allows power to be transferred from the driveshaft on to the axle, and with such an important component, it should be cared for and maintained sufficiently.
