Panhard rod

[1] Originally invented by the Panhard automobile company of France in the early twentieth century, this device has been widely used ever since.

Jaguar also used a Panhard rod to locate the rear axle on its unusual cantilever leaf sprung Mark 2.

Its major disadvantage is that the body must necessarily move in an arc relative to the axle, with the radius equal to the length of the Panhard rod.

A suspension design that is similar but dramatically reduces the sideways component of the axle's vertical travel is a Watt's linkage.

The Mercedes-Benz G-Class was redesigned in 2018 to include a Panhard rod on the rear axle to improve its on-road handling characteristics.
