I wish my Polo had a double wish bone system. The strut after a slow speed roll popped from the top and of course I'm lucky to be alive. Still miss my Polo, though.
If designing a car for yourself go for wishbones, if designing a car to mass produce go for McPherson struts on the front; McPherson struts also have a naturally high roll centre which is another reason manufacturers like them for the front, also they work well on 911’s and similar with a light front end.
McPherson struts, manual transmission, 50 years with no problems. Main determining factor in the amount of car "waddle" is the center of gravity. When I had to switch from a low center of gravity to a higher one as the car model design changed, I suddenly found my favorite twisty road to play on became a guessing game for when the balance shifted in a curve. The car lurched from side to side seemingly at random. Never found a way to balance that out. Another thing with the higher vehicle was what was in the trunk. Basketballs, soccer balls, footballs, anything with a slick bottom slid or rolled back and forth worse than a ship's utility boat in a light chop. Fortunately I don't get seasick, that would be just too much fun.
Strut design requires heavier metals on struts to hold the weight of the car. Steel and cast iron parts are used for them, adding weight. Double wishbone allows upper and lower arms to share weight, with suspension dampers handling only dynamic load. Each of the three can be made in lighter aluminum, reducing overall weight for practical applications
To be fair that pic of the Xt on a flatbed trailer wasn't smashed up in the front end - which would be more believable. The brake issue was a very small limited number. Now the steering assist error or rather the thermostat and sensor error is a big problem that will cost you 4hr shop labor and maybe a couple hundred in parts if you're not a handyman.. However, this is not limited just to the Cadillac but other GM cars. It is still a great vehicle as long as you don't abuse it.
This video is pretty much incorrect.. struts take up more space and higher up in the engine compartment. also, the amount of material needed to hold the strut secure adds weight, and takes space. struts make for heavy large 1 peice body (unibody) designs, where a arms use a (frame) where body panels are replaceable, and not part of the structure.
Они ещё, к тому же лучше гасят колебания. Только требуют большего внимания для шаровых опор, так как их там две: нижняя и верхняя. А в стойке Макферсон лишь одна- нижняя.
