What are the advantages and disadvantages of MacPherson independent suspension?
The advantages of MacPherson independent suspension are: better responsiveness and maneuverability, and simple construction, occupies little space, low cost, lighter weight, suitable for the arrangement of large engines and assembled in small cars.
Other advantages are:
1, with a large effective distance C, the force acting on the body at the connection points E and D is small;
2, points G and N in the middle of only a small distance D;
3, the spring stroke is large;
4, elimination of 3 places of support;
5, easy to construct the shape of the front underbody.
McPherson type suspension consists of coil springs, shock absorbers, triangular lower arms, and in most models, a horizontal stabilizer bar. The main structure is simple to say that the coil springs are set on the shock absorber, the shock absorber can prevent the coil springs from deviating to the front, rear, left and right when the force is applied to them, and limit the spring only to vibrate in up and down direction, and the length of the stroke of the shock absorber and the tightness and looseness of the shock absorber can be used to set up the suspension's soft and hardness and performance.
McPherson independent suspension defects are: driving on uneven roads, the tires are very easy to automatically steer, so the driver must exert force to maintain the direction of the steering wheel, when suffered a strong impact, the sliding column is easy to lead to the bending, thus affecting the steering performance. Stability is poor, anti-roll and braking nodding ability is weak, after adding stabilizer bar there is some relief but can't deal with the problem from the source, durability is not high, shock absorber is very easy to leak oil must be replaced regularly.
