What are the types of non-independent suspensions?
2 Answers
Non-independent suspension types include: 1. Torsion beam axle: Primarily used in front-engine, front-wheel-drive vehicles. When body roll occurs, the torsion beam's twisting causes changes in wheel camber; 2. Twist-beam type: Features a torsion beam between left and right trailing arms, creating an H-shaped suspension configuration where the system connects to the body via the front of trailing arms; 3. Parallel leaf spring type: Uses two parallel-mounted leaf springs to support the axle, serving both as shock absorbers and axle positioning components. Non-independent suspension is a structural design contrasting with independent suspension, characterized by connecting both wheels via a solid axle that mounts to the frame or body through elastic suspension components.
I've been driving for many years, and the common types of non-independent suspensions aren’t actually that complicated—there are mainly two: torsion beam suspension and solid axle suspension. The torsion beam suspension is like a rod connecting the two rear wheels, simple in structure and cheap. Many family sedans, such as the Hyundai Lavida, use this type for their rear suspension. The solid axle suspension is sturdier, resembling a solid axle supporting the wheels, making it suitable for rough roads and commonly found in SUVs like the Toyota Prado. There’s also an old-school type called the Panhard rod suspension, but it’s rarely seen nowadays. The advantages of these suspensions are low cost and durability, making them ideal for budget cars or off-road vehicles. The downside? They offer less comfort and can feel shaky on bumpy roads. Overall, checking the rear suspension type when buying a car is crucial—it affects the overall driving experience, especially when on a tight budget, as opting for a non-independent suspension can save some money. Don’t overlook its maintenance; regularly inspect the shock absorbers and connecting components to prevent premature wear.
