Panhardská rod

The suspension solid axle passenger cars and light trucks are nowadays almost exclusively used coil springs. Coil springs have replaced the previously used leaf springs, whose essential function was also the axle. Coiled spring has no lateral line (does not bear almost no lateral forces) and therefore lead to the longitudinal rigid axle with coil springs serve two or four arms. In the transverse direction is transverse to ensure management arm (called Panhardskou bars).

Principle:

The diagram shows the function of the vertical bars Panhardské body movements, respectively. solid axle. The figure shows that during suspension of the vehicle under the influence of exposure to the side bars Panhardské feed solid axle. With this movement involves lateral vibration of the superstructure, which exacerbates comfort. For these reasons, the horizontal position Panhardské rods and rod itself should be as long as possible. This minimizes lateral displacement of the axis "y".

History:

Name Panhardská rod was by the name of a French car that the solution in the twenties of last century used as the first.
