What are the types of non-independent suspensions?
2 Answers
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.
