The function of the steering damper is to sleep on the car steering wheel, prevent vibration or forced vibration, and prevent braking deviation. The purpose of suspension shock absorbers is to avoid excessive impact loads. The working principle depends on the steering damper. The working principle of the steering damper is to use a piston orifice to create a damping effect under the throttling action of the liquid in the shock absorber. The working principle of the suspension shock absorber is that when the piston inside the shock absorber moves relative to the vibration, the oil in the shock absorber cavity will flow repeatedly from one cavity to the other. Steering dampers are installed on the car's steering system. Suspension shock absorbers are mounted between the frame and axle.
Suspension is the main power system of a car. During acceleration and braking, rotational force is applied to the suspension through the tires, and pressure and resistance are applied to the suspension by the chassis, so the suspension must be strong enough but as light as possible. Unlike road cars, race cars use internal springs and dampers. The springs can cushion the vertical movement of the wheels, but any vibration will reduce the tire grip and affect the maneuverability of the car, so dampers are needed to limit the vibration of the springs. It can transmit the force and force torsion acting between the wheel and the frame, and buffer the impact transmitted from uneven roads to the frame or body, thereby reducing the vibration generated and allowing the car to drive smoothly. Suspension is actually the general term for all components that connect the body and wheels.
The function of the spring is to absorb the impact from the ground. The function of shock absorption is to absorb the elasticity of the spring. All links and swing arms are used to transmit the force on the wheel so that the wheel does not deviate from the direction and moves according to the prescribed trajectory. The softer the spring and shock absorption, the better the absorption of road fluctuations, the higher the suspension comfort, but the corresponding body stability will also decrease. The smaller the spring deformation, the better the support for the body, the better the stability of the vehicle, and the better the corresponding operability, but it will also affect the ride comfort. Comfort and maneuverability are two traits that are always at odds in most price ranges. A hanging object that allows each wheel to be independent of each other and not affected by the running of the other wheel.
When it is unavoidable and only one wheel can pass through the pit, the four wheels of the car are hung independently. The side that does not pass through the pit will tilt much lighter and the passenger's feeling will not be bad. Independent suspension also has disadvantages. Because there are so many parts, independent suspensions generally encroach on more space and increase costs accordingly. Some complex independent suspensions are more often installed on heavy vehicles. Without independent suspension, the left and right wheels are all connected to the body. If the left wheel runs, it will also be transmitted to the right wheel. So it is often called scooter suspension. Someone else changed the name of the semi-independent suspension.
