Three chassis mounting points, one for the driveshaft, two for the I-arm.
Three upright mounting points, one for the driveshaft, two for the I-arm.
In the Jaguar IRS all driving and braking loads are reacted by the lower lateral I-arm in torsion and bending. Reactions to all wheel centre inputs in the longitudinal direction result in torsional loading of the lower member. The fixed length (and fixed universal joints) driveshaft acts as the upper camber control link and controls the front view instant centre. The side view instant centre is controlled solely by the lower member.
The chassis top pivot point corresponds to the inboard driveshaft universal joint centre.
The upright top pivot point corresponds to the outboard driveshaft universal joint centre, and only the lateral value is entered.
The toe control pivot points are already established as part of the basic suspension geometry. There is only the capability to display the toe changes.
There is no option to specify the Driveline configuration since these points have already been specified within the Chassis Geometry, and the calculation style is alwaysâ€œFixedâ€ as the driveshaft cannot change length.
