automotive suspension components is important to ensure riding comfort. Meanwhile, the force-transmitting parts as automotive suspension frame (or body) as between the axle (or wheel) is connected, it is important to ensure the safety member cars. Automotive suspension member comprises a resilient three parts, shock absorbers and other force transmission means, respectively, acts as a buffer, and the damping force of transfer. Type front suspension, by definition, refers to the car’s front suspension form. In general, the vast majority of the front passenger car suspension independent suspension, usually in the form of MacPherson, multi-link, double wishbone or double wishbone.

automotive suspension components is important to ensure riding comfort. Meanwhile, the force-transmitting parts as automotive suspension frame (or body) as between the axle (or wheel) is connected, it is important to ensure the safety member cars. Automotive suspension member comprises a resilient three parts, shock absorbers and other force transmission means, respectively, acts as a buffer, and the damping force of transfer. Type front suspension, by definition, refers to the car’s front suspension form. In general, the vast majority of the front passenger car suspension independent suspension, usually in the form of MacPherson, multi-link, double-wishbone orDouble wishbone.
2. McPherson suspension substantially description
McPherson is today one of the most popular independent suspension, typically for the front wheels of the car. Briefly, the main structure of the McPherson suspension coil spring that is coupled with a shock absorber, coil spring can be avoided when forward force of the shock absorber, rear, left, right offset phenomenon, only to limit the spring vibration can be vertical, and may be elastic and the length of stroke of the damper, soft and hard setting and performance suspension.
McPherson suspension advantage that satisfactory performance in driving comfort, the small volume of the structure, can effectively expand the interior passenger space. However, since it is configured as a straight type, the impact of the lack of blocking force left-right direction, anti-poor braking effect nodded.
3. The multi-link suspension is introduced substantially
The multi-link suspension is more advanced suspension, comprising a four-bar linkage, and other five-bar linkage, and a suspension damper such as a coil spring is not rotated as in the Macpherson suspension knuckle; can be more precise control over the wheel angle contact with the ground, making the car good handling stability, and reduced tire wear.
However, many multi-link suspension element employed, the large space, the complex structure and high cost, small vehicles because of cost and space considerations rarely used such suspension.
4. The double-wishbone suspension substantially description
double-wishbone suspension, also known as double A-arm type independent suspension, has a double-wishbone suspension upper and lower wishbones, transverse forces are absorbed by two fork arms at the same time, carrying only the strut body weight, so a large lateral stiffness. A fork-shaped upper and lower arms can be precisely positioned double-wishbone front suspension of the various parameters, when the nose wheel steering, two upper and lower wishbones can absorb suffered tire lateral force, combined with the two fork arms lateral rigidity is large, a smaller turning roll.
McPherson double wishbone suspension as compared to a plurality of the rocker arm, not only to take up more space, and it is difficult to determine location parameters, and therefore the front axle for a small car space and cost generally do not consider use of such suspension. However, it has a small roll, tunable, large ground contact area of the tire, grip performance, and therefore most of the pure blood of the car front suspension are made of double-wishbone suspension, it can be said double-wishbone suspension is green suspension movement, Ferrari, Maserati sports car and the like F1 – uses a dual arm front suspension fork.
5 double wishbone suspension substantially description
double wishbone suspension and double-wishbone suspension has many similarities, only structures than the dual wishbone simpler, may be referred to as a simplified version of the double-wishbone suspension. With double-wishbone suspension as double wishbone suspension lateral rigidity is relatively large, generally up and down swing arm unequal length. While some of the double wishbone upper and lower arms can not play the role of a longitudinal guide, but also an additional lever guide. This double wishbone relatively simpler structure double wishbone suspension performance between McPherson suspension and between the double-wishbone suspension, has good athletic performance, is generally used in Class A or Class B family cars.
