I. McPherson Independent Suspension
Advantages: McPherson suspension has good responsiveness and maneuverability, simple structure, small occupied space, low cost and light weight, and is suitable for arranging large engines and assembling on small cars.
Disadvantages: when driving on uneven roads, the wheels are easy to turn automatically, and the driver must keep the direction of the steering wheel hard. When subjected to severe impact, the strut is easy to bend, thus affecting the steering performance. Poor stability, weak anti-roll and braking nodding ability. After adding stabilizer, it was relieved, but it could not solve the problem fundamentally. The durability is not high, and the shock absorber is easy to leak oil, so it needs to be replaced regularly.
Second, multi-link independent suspension.
Multi-link suspension system is divided into five-link rear suspension system and four-link front suspension system. The five-link rear suspension system consists of five links: control arm, rear positioning arm, upper arm, lower arm and front positioning arm, in which the control arm can adjust the toe-in of the rear wheel.
The advantages of five-bar suspension are simple structure, light weight and small space occupied by suspension system. 5. The rear suspension with connecting rod can realize the optimal position of caster angle of kingpin, greatly reducing the front and rear force from the road surface, thus improving the ride comfort and comfort during acceleration and braking, and also ensuring the stability of straight driving, because the lateral deviation of the wheel caused by the tension or compression of the coil spring is very small, and it is not easy to cause non-straight driving. When the vehicle turns or brakes, the five-link rear suspension structure can make the rear wheels form toe-in, improve the control performance of the vehicle and reduce understeer. At the same time, the compact structure increases the space of the rear seat and luggage compartment. Because of its remarkable advantages and easy adjustment, this kind of suspension is widely welcomed. Million car purchase subsidy
