Vehicle architecture and integration
The CV Joint System provides the dynamic connection between engine and driving wheels, transmitting power and allowing steering angles whilst accommodating suspension movements and isolating vibrations. Each sideshaft has two CV Joints – a fixed joint at the wheel end and a plunging joint at the gearbox end, connected by an interconnecting shaft.
At GKN Driveline, we appreciate the impact of this critical technology on a vehicle’s dynamic performance, noise, vibration, durability, efficiency and weight saving, and their key role in enhancing power delivery, handling and comfort.
Elements of a CV Joint System
A CV Joint System consists of a number of components.
The fixed joint is on the sideshaft system’s outboard side, attached to the vehicle’s wheel hub bearing unit, and must offer a wide range of articulation angles to meet the specific criteria for steering and suspension movement. GKN offers a range of best-in-class options, including the SX joint based on the Countertrack principle.
The interconnecting shaft connects the inboard and outboard CV joints and is available as a solid barshaft or as a hollow welded or Monobloc tubular shaft.
GKN supplies a comprehensive range of plunging joints for front and rear-wheel drive vehicles, offering a broad selection of articulation angles. The plunging joint, attached to the differential end of the sideshaft system, is vital to desired vehicle performance and has a significant impact on ride comfort, noise and vibration
Sealing systems, or boots, are required to keep the lubricant inside the joint and to prevent dirt and moisture or any other contaminating substance from getting into the joint. GKN has developed a range of boots that help reduce the weight and packaging of the sideshaft system.
Global vehicle platforms must accommodate a wide range of powertrains with different power outputs. One of the main challenges for engineers is how to keep suspension geometries and dimensions common while also optimizing the car's performance, efficiency and refinement?Find out more
