What is a Sideshaft (Driveshaft)?

A sideshaft is a system that transfers power from a differential to the wheels allowing articulation and movements due to steering or suspension travel.

The system has three major elements;

Inboard Constant Velocity Joint (CVJ) including lubrication and sealing system
Interconnecting shaft
Outboard Constant Velocity Joint (CVJ) including lubrication and sealing system

What is a CVJ? - Wikipedia

In most applications, the inboard CV Joint is a plunging joint that allows the effective length of the sideshaft to adjust due to suspension movement. In front (or steer) axle applications, the outboard joint must transfer power effectively through a wide range of angles (up to 52 degrees). In rear axle applications, joint operation angles are much lower. 

Sideshaft (Driveshaft) Types


The combination of these joints with the solid barshaft represents the most common solution for front-wheel-drive (FWD) cars. Within reasonable installation conditions it’s performance ensures good NVH and durability for the majority of vehicles.


This solution is chosen for more premium front-wheel-drive (FWD) vehicles where the UF joint provides high articulation for a small turning circle and the AAR joint allows higher installation angles with excellent NVH and durability performance. In combination with the MTS the driveshaft is tuned for light weight, optimised stiffness and the highest level of ride comfort.


Driveshafts with this configuration are the preferred solution for premium rear-wheel-drive (RWD) cars. The compact VL joints with low backlash and optimised plunge resistance support the desired features of these vehicles. The use of the MTS allows for high torsional stiffness and light weight.


Sport utility vehicles (SUV) of the new generation are combining high level of ride comfort with the occasional off road capability. With the required suspension design and the resulting wheel travel the performance requirement exceeds the traditional driveshaft design limits. The solution with countertrackTM- and SIO-joints and a ballspline plunging device provides the necessary high articulation and long plunge capability to suit these applications. The ballspline also ensures the highest level of NVH refinement.


For very small and very large vehicles the universal combination of UF- and DO-joints together with a solid barshaft is the recommended choice. Positive contribution of the UF towards achieving small turning circles and the versatility of the DO-joint for driveshaft applications are ideal for these vehicle segments. Suitability for manual and automatic gearboxes and feasibility for high installation angles come together with an acceptable NVH performance.


For special low cost rear wheel drive vehicle applications, the GI-GI driveshaft provides a superior niche solution. This driveshaft is fully adapted to the specific vehicle requirements, offering adequate NVH, strength and durability in smallest packaging. Latest state-of-the-art manufacturing technology and sealing system ensure high robustness and reliability.
