What are the disadvantages of a double ball joint suspension?
2 Answers
The drawback of a double ball joint suspension is that it cannot balance both comfort and handling. This type of suspension offers better handling but reduces comfort and makes the steering feel heavier. Below are the relevant details: 1. Double Ball Joint Suspension: The double ball joint suspension is actually an improved version of the MacPherson suspension. It replaces the L-shaped control arm of the MacPherson suspension with two links, creating two connection points between the suspension and the knuckle, hence the name double ball joint suspension. 2. Advantages: The double ball joint suspension can enhance the car's handling and improve steering precision. Many sporty cars from BMW use the double ball joint independent suspension, including many M Power series models.
I haven't been driving for long, and the double-wishbone suspension really gives me a headache. The main drawback is that it's too expensive. The parts are complex, and the replacement costs are high. Last time my car had a problem, it cost me several thousand yuan to fix it. The mechanic said the suspension ball joints are prone to wear and tear, and if they break, the whole system needs to be inspected, making maintenance a real hassle. It's also quite heavy, affecting fuel consumption, and on long drives, the car feels sluggish, making the throttle harder to press. It takes up a lot of space too, cramming the front engine bay full, making it difficult to fit any additional accessories, and the heat dissipation isn't great. When driving on bumpy roads, the noise is particularly noticeable, making my ears ring and significantly reducing comfort. In short, if you're a beginner or want to save time and money, I really don't recommend this type of suspension. I later switched to a simpler type, and it's been much more worry-free.
