Roll & Pitch Axis

Roll Center

The Roll Center is the intersection point between the left and right planes, which are defined by the instant axis and contact patch point, and the vertical plane between the left and right contact patches.  This Point is not stationary, it can move as the suspension articulates.

Roll Axis

The Roll Axis is a line drawn between the Front and Rear Roll Centers. This is the axis about which the Suspended Mass rotates around. This axis is often called the Kinematics Roll Axis.

Pitch Center

The Pitch Center is the intersection point between the front and rear planes, which are defined by the instant axis and contact patch point, and the vertical plane between the front and rear contact patches.  This Point is not stationary, it can move as the suspension articulates.

Pitch Axis

The Pitch Axis is a line drawn between the left and right Pitch Centers. This is the axis about which the Suspended Mass pitches about. This axis is often called the Kinematics Pitch Axis.
