What are the types of non-independent suspensions?

[KateRose]

Non-independent suspension types include torsion beam axle, torsion beam type, and parallel leaf spring type. The following are specific introductions to the types of non-independent suspensions: Torsion beam axle: Mainly used in front-engine, front-wheel-drive models. When the car experiences body tilt, the torsion of the torsion beam axle causes changes in the wheel camber angle. Torsion beam type: A torsion beam is installed between the left and right trailing arms, making the suspension resemble an H-shape. The suspension system connects the front end of the trailing arms to the vehicle body. Parallel leaf spring type: This type uses two sets of parallel-mounted leaf springs to support the axle. The leaf springs can serve both as shock absorbers and as axle positioning tools. Non-independent suspension is a suspension structure relative to independent suspension, characterized by both wheels being connected by an integrated frame, with the wheels and axle together suspended under the frame or body through an elastic suspension system.

As a car enthusiast, I've encountered various types of non-independent suspensions while driving. The most common is the torsion beam suspension, used in the rear of many family sedans; for example, compact cars have their rear wheels connected by a transverse beam, which causes noticeable wobbling when going over bumps. Then there's the solid axle suspension, often used in SUVs or pickup trucks, where the rear axle is fixed to a rigid bar—great for off-road stability but too harsh for city driving. The advantage of non-independent suspension is its simple, inexpensive structure and easy maintenance, but it sacrifices comfort. On uneven roads, when one wheel is impacted, the other moves along with it, making long-distance driving more fatiguing. When choosing a car, I prioritize this aspect because it significantly affects the overall driving experience.

Over the years of repairing cars, the non-independent suspensions I've encountered mainly fall into two categories: torsion beams and solid axles. Torsion beams are commonly found at the rear wheels of compact cars, where a curved beam handles the connection. Solid axles are more frequently seen at the rear of SUVs, with the wheels fixed to a single axle. When inspecting these, issues often arise from worn rubber bushings or loose bolts, leading to abnormal noises while driving. They are designed to be simple, durable, and cost-effective, but offer much less comfort, especially causing noticeable body roll on rough roads. While economical for daily use, regular maintenance is crucial, such as lubricating the joint components. If any abnormalities are noticed, it's advisable to get them checked early to prevent minor issues from escalating into major problems.

I usually commute by car, and the most common type of non-independent suspension is the torsion beam, which is installed in the rear of many entry-level cars, with wheels paired together. Driving on bumpy roads, you can feel the entire chassis bouncing, which isn't very comfortable. However, its advantages are obvious: it saves money and space, making it suitable for budget-conscious vehicles. Solid axles are also found in larger vehicles, like old-school Jeeps, offering strong stability but lower comfort. Overall, this type of suspension is acceptable for simple driving scenarios but less ideal for long trips or rough terrain. Choosing a car requires balancing cost and comfort.

Discussion on non-independent suspension, focusing on the system connecting the wheels. The torsion beam is the most popular, with a single beam fixing both wheels, offering low cost and easy maintenance. The solid axle is used in some trucks or four-wheel-drive vehicles, featuring an integrated wheel axle structure that is robust. The advantages are durability, affordability, and simple manufacturing; the disadvantages are the inability to buffer independently, affecting handling and comfort, with significant rear-end bouncing on uneven roads. After optimization in design, it is suitable for economy cars, but may be unstable during high-speed cornering. Understanding these aspects is helpful for car selection.

As a car owner, I've researched non-independent suspensions like torsion beams. They're commonly used in the rear wheels of entry-level cars, where two wheels share a single support structure, resulting in a stiff ride where vibrations from speed bumps are directly transmitted into the cabin. The advantage is a simple design and good cost control, allowing manufacturers to save money for other areas. The downside is a significant compromise in comfort, especially noticeable when fully loaded. Solid axles are common in off-road vehicles, providing sturdy support but sacrificing ride smoothness. When buying a car, I'd skip it—if the budget allows, choosing a car with independent suspension is much more comfortable.
