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 |

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.
