What are the types of non-independent suspensions?
4 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.
I often help out at the auto repair shop, and there are two main types of non-independent suspension: one is the torsion beam, and the other is the solid axle. The torsion beam suspension connects the wheels with a crossbeam, commonly used in small cars like the Volkswagen POLO for the rear wheels. It's easy to install and resistant to fatigue, but it can be quite bumpy over potholes. The solid axle suspension uses a solid axle, often found in rugged vehicles like the Jeep Wrangler for the rear suspension, capable of handling heavy loads and off-road impacts. Besides these, there are early designs like the trailing arm, but they are rarely used nowadays. In terms of selection, small cars typically use torsion beams for cost savings, while trucks and SUVs rely on solid axles for stability. When using them, pay attention: if the suspension wears out quickly, check the springs and bushings, and don't wait for strange noises to repair. When modifying a car, don't randomly change the suspension type—the original design is the safest, especially since comfort can vary significantly at high speeds.
To be honest, there are essentially two types of non-independent suspensions: torsion beam and solid axle. The torsion beam fixes the rear wheels to a flexible beam, featuring an extremely simple structure that's both affordable and durable, commonly seen in the rear wheels of regular sedans. The solid axle uses a rigid shaft for direct support, making it sturdy and tough, often found in the rear suspension of off-road vehicles. The difference between the two is clear: solid axles are better suited for rough roads, while torsion beams are more geared towards urban commuting. Why do automakers still use them? They're cost-effective and efficient, plus maintenance is easy. It's recommended that car owners regularly maintain their suspension systems to extend their lifespan.
