How does a constant-velocity (CV) joint differ from a traditional universal joint?

A constant-velocity (CV) joint differs from a traditional universal joint in several ways. Here’s a detailed explanation:

A traditional universal joint (U-joint) and a constant-velocity (CV) joint are both used for transmitting torque between non-aligned or angularly displaced shafts. However, they have distinct design and operational differences:

• Mechanism: The mechanism of torque transmission differs between a U-joint and a CV joint. In a U-joint, torque is transmitted through a set of intersecting shafts connected by a cross or yoke arrangement. The angular misalignment between the shafts causes variations in speed and velocity, resulting in fluctuating torque output. On the other hand, a CV joint uses a set of interconnected elements, typically ball bearings or roller bearings, to maintain a constant velocity and torque output, regardless of the angular displacement between the input and output shafts.
• Smoothness and Efficiency: CV joints offer smoother torque transmission compared to U-joints. The constant velocity output of a CV joint eliminates speed fluctuations, reducing vibrations and allowing for more precise control and operation. This smoothness is particularly advantageous in applications where precise motion control and uniform power delivery are critical. Additionally, CV joints operate with higher efficiency as they minimize energy losses associated with speed variations and friction.
• Angular Capability: While U-joints are capable of accommodating larger angular misalignments, CV joints have a limited angular capability. U-joints can handle significant angular displacements, making them suitable for applications with extreme misalignment. In contrast, CV joints are designed for smaller angular displacements and are typically used in applications where constant velocity is required, such as automotive drive shafts.
• Operating Angles: CV joints can operate at larger operating angles without significant loss in torque or speed. This makes them well-suited for applications that require larger operating angles, such as front-wheel drive vehicles. U-joints, on the other hand, may experience speed fluctuations and reduced torque transmission capabilities at higher operating angles.
• Complexity and Size: CV joints are generally more complex in design compared to U-joints. They consist of multiple components, including inner and outer races, balls or rollers, cages, and seals. This complexity often results in larger physical dimensions compared to U-joints. U-joints, with their simpler design, tend to be more compact and easier to install in tight spaces.

In summary, a constant-velocity (CV) joint differs from a traditional universal joint (U-joint) in terms of torque transmission mechanism, smoothness, efficiency, angular capability, operating angles, complexity, and size. CV joints provide constant velocity output, smoother operation, and higher efficiency, making them suitable for applications where precise motion control and uniform power delivery are essential. U-joints, with their ability to accommodate larger angular misalignments, are often preferred for applications with extreme misalignment requirements.
