Universal joints allow drive shafts to move up and down with the suspension while the shaft is moving so power can be transmitted when the drive shaft isn't in a straight line between the transmission and drive wheels. ... On rear-drive vehicles, one sign of a worn U-join is a “clank” sound when a drive gear is engaged.

Why do we use universal coupling?
A universal joint is a mechanical device that allows one or more rotating shafts to be linked together, allowing the transmission of torque and/or rotary motion. It also allows for transmission of power between two points that are not in line with each other.
What is a universal joint shaft?
A universal joint is a positive, mechanical connection between rotating shafts, which are usually not parallel, but intersecting. They are used to transmIt motion, power, or both. The simplest and most common type is called the Cardan joint or Hooke joint. ... The angle between the two shafts is called the operating angle.
Why is universal joint used in propeller shaft?
In the transmission shaft of an automobile, two universal joints are used – one between main transmission shaft and propeller shaft and another between other end of propeller shaft and the differential. Therefore, the universal joints make the joints flexible so that power can be transmitted at an angle.
Do universal joints work at 90 degrees?
It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint.
Why are two universal joint required?
Especially for friction bearing joints, the transmittable torque decreases swiftly with increasing angle. A reduction in operating angle per joint by using a double universal joint in w configuration can reduce bearing stress and provide constant velocity operation of the input and output shaft.
How are universal joints manufactured?
A universal joint is a connection between two objects, typically shafts, that allows relative rotation in two axes. It is made up of two revolute joints with perpendicular and intersecting axes. ... It is possible to create a constant velocity joint by combining a number of universal joints.
What is the difference between knuckle joint and universal joint?
Solution) The chief advantage of the universal joint over knuckle joint is its flexibility. The joint can serve the shafts which do have angular misalignment. It is cheap as well as cost effective too.
How do you test a universal joint?
If a u-joint is excessively worn, there's an easy test you can perform. With your foot on the brake, shift the car into reverse. Then, shift into drive. If the vehicle makes a clunking sound, or you can feel it knock one time after engagement, a u-joint is likely the culprit.
What are the different types of universal joint and what are the function of each universal joint?
There are two types of universal joints, defined by their number of bending joints: Single joint: has only one bending aspect and is capable of operating at up to a 45-degree angle. Double joint: utilizes two bending joints, the double u-joint can operate at angles up to 90 degrees.
Why are two universal joints often used when there is angular misalignment between two shafts?
Angular misalignment between two shafts connected with a flexible coupling introduces an additional driving force that can produce torsional or lateral vibrations. The forces in a typical industrial coupling are similar to those in a universal joint (Figure 18-2).
What is an example of a universal joint?
A universal joint, otherwise called a u-joint, is found in many automotive applications, as well as in other mechanics. For example, a u-joint is used in vehicles between the drive train bar and the transmission or axle where the bars meet at a right angle.
How far can a universal joint bend?
Most significant is the ability of the universal joint to operate at high misalignment angles. Operating angles up to 15 degrees are not uncommon. Another feature of the universal joint is the bearing and seal design that resists lubrication loss and contamination.
Are all universal joints the same?
Nearly all U-joints have one side that is pressed into a welded-in yoke while the other side bolts into the other yoke. The press-in sides use C-clips to hold the caps in place. There are outside and inside locks, and in most cases they are not interchangeable.
How many parts are required for assembly of universal coupling?
A universal joint is a positive, mechanical connection used to transmit motion, power or both. Each universal joint assembly consists of three major components: two yokes (flange and weld) and a cross trunnion.
