Rubber Suspension Bushings: How do they work?
Rubber Suspension Bushings: How do they work?
(OP)
Simply a question stemming from curiosity: how do the rubber suspension bushings in autos actually work? Which surface is the rubbing surface? I have looked at many, and it seems to me that they mostly stretch the rubber through the limited angles of motion they see in actual operation. They work well without lubrication, in all kinds of nasty dirt, and last a long time.

The suspension arms can therefore rotate fairly freely by allowing the rubber to twist, but the connection is stiff enough in compression to give fairly positive location.
The rubber can also absorb small amplitude high frequency noise and vibration, which is the main advantage. And there is nothing that can slowly wear out and then rattle, and no lubrication or maintenance is usually required.
