What system does the suspension belong to in the chassis?
2 Answers
Suspension is the driving system of the chassis, which connects the wheels to the car body. Without suspension, a car cannot be driven properly. The suspension system refers to all the force-transmitting connection devices between the car frame and the axle or wheels. Its functions are: to transmit forces and torque between the wheels and the frame, to cushion the impact from uneven road surfaces to the frame or body, and to dampen the resulting vibrations, ensuring smooth driving. Types of car suspensions include: 1. Independent suspensions, which consist of: double-wishbone suspension, double-trailing-arm suspension, E-type multi-link suspension, multi-link suspension, and MacPherson strut suspension; 2. Non-independent suspensions, which include: multi-leaf spring suspension, torsion beam suspension, leaf spring non-independent suspension, coil spring non-independent suspension, and air spring non-independent suspension.
Simply put, the suspension is the key system of a car's chassis, specifically responsible for connecting the wheels to the body and absorbing vibrations and bumps from various road surfaces. What I care about most when driving is comfort—the suspension effectively reduces vehicle sway, making long-distance driving less fatiguing. Especially on bumpy roads, a good suspension keeps the vehicle stable, preventing passengers from being jostled around uncomfortably. Additionally, the suspension enhances safety by ensuring the tires maintain solid contact with the ground, allowing for more timely braking in emergencies. If the suspension is old or damaged, such as loose springs or failed shock absorbers, the car can become unstable and even produce abnormal noises, severely affecting the driving experience. Therefore, I recommend regularly inspecting suspension components to identify potential issues early.
