View Full Version : how swaybars and endlinks work

I have a fuzzy idea about how a swaybar works and about the role endlinks play. So Ill ask a couple of questions to get this topic off.

Do endlinks work in tension only? I ask this question since - for me - the answer points me to a fundamental direction.

Regarding a front wheel drive car, once the inside rear wheel leaves the ground, the swaybar contributes nothing to weight transfer. True or false?

I understand that a swaybar twists, but my intelect tells me that once a tire leaves the ground this twist begins to unwind?

My conceptual picture while facing a front wheel drive car from the rear;

The car turns right and leans to the left. In doing so, the left hand side of the swaybar twisit counter clockwise or toward the rear of the car pulling the endlink down. This twist or kinetic tension in an attempt to releive itself applies a transfer of weight across the car to the inside front wheel. Is this correct?

I've tried to glean some of this info from Milliken, but this is not my field.

Thank you so much, in advacne, for your help.

Hi,

May we suggest you look at this from another perspective.

When the car is travelling in a straight line, both (left and right) control/trailing arms should in theory be "level", resulting in zero swaybar twist/tension.

When the car turns right and leans left this will cause the right arm to droop whilst the left arm to rise into the guard immediatly twisting the Swaybar.

As the swaybar is twisting, it is constantly trying to level out the arms reducing roll regardless of whether or not the inside wheel is in contact with the ground or not.

I hope this helps!
