What are the classifications of suspension systems?
3 Answers
The classifications of suspension systems are: 1. Based on the control form, they are divided into passive suspension systems and active suspension systems; 2. Based on the vehicle's guiding mechanism, they can be classified into independent suspension systems and non-independent suspension systems. The suspension system is the general term for all force-transmitting connection devices between the vehicle's frame and the axle or wheels, consisting of elastic elements, guiding mechanisms, shock absorbers, buffer blocks, and lateral stabilizer bars. The functions of the suspension system are: 1. To transmit forces and torques between the wheels and the frame; 2. To buffer the impact forces and vibrations transmitted from uneven road surfaces to the frame or body; 3. To ensure the wheels move within a fixed angle, maintaining stable steering; 4. To support the weight of the wheels; 5. To maintain good contact between the wheels and the ground.
I remember feeling the difference in suspension when I drove my friend's car last time. Basically, there are two main types: independent and non-independent suspension. With independent suspension, each wheel can bounce up and down independently, like MacPherson strut or multi-link systems. My family car uses MacPherson struts, and it feels much smoother and less bumpy on rough roads. Non-independent suspension, such as torsion beam, connects two wheels together. It's cheaper and suitable for small cars, but you feel more shaking when going over speed bumps, which isn't very comfortable. Semi-independent suspension is a middle-ground option, balancing economy and comfort. The type of suspension affects driving safety, so when choosing a car, consider the road conditions. For city driving, independent suspension is better.
I'm a car enthusiast who often researches suspension system classifications. The mainstream categories are independent and non-independent types. Independent suspensions include MacPherson strut—simple structure, easy maintenance; double wishbone—precise handling; multi-link—excellent comfort. Non-independent types like torsion beam are suitable for economy models but offer poor comfort. There are also advanced options like air suspension, which can adjust height and stiffness to enhance off-road performance. Different types determine a car's behavior: independent suspensions reduce wheel interference, providing more stability in corners; non-independent types are simple and durable. Suspension modifications also need to match the tires.
