What is the Difference Between Torsion Beam Suspension and Independent Suspension?
2 Answers
The differences between torsion beam suspension and independent suspension are: 1. Different functions: Torsion beam suspension has torsional stiffness, reducing vibration through elasticity; independent suspension offers certain comfort with more linkages, keeping the wheels perpendicular to the ground and minimizing body tilt. 2. Different applications: Torsion beam suspension is used for trucks, ordinary buses, and small cars; independent suspension is used for medium and large-sized cars. Independent suspensions include MacPherson strut, double-wishbone, multi-link, double A-arm, and double ball joint suspensions. The function of independent suspension is: The axle of an independent suspension is divided into two sections, with each wheel independently mounted under the frame via coil springs. When one wheel jumps, the other wheel is unaffected, allowing both wheels to move independently, thereby improving the vehicle's stability and comfort.
Torsion beam suspension and independent suspension are two common chassis structures, with the main difference being whether the wheels are interconnected. A torsion beam is like a rigid rod connecting both wheels; when encountering bumps on the road, the two wheels pull on each other. Its advantages include a simple structure, low maintenance costs, and durability, making it commonly used in ordinary family cars like small SUVs, suitable for flat roads. Independent suspension, on the other hand, allows each wheel to move separately without affecting the others, similar to how legs swing freely when walking. This results in more stable body movement over speed bumps or potholes, less shaking, a more comfortable ride, and better handling and cornering flexibility. However, it comes with higher costs, more components, and more complex maintenance. I've tried both types of cars, and the independent suspension is noticeably smoother, especially providing more confidence when driving on mountain roads.
