What does the McFford style mean in car suspension?

MacPhersan suspension is a type of independent suspension, which is one of the most popular independent suspensions today, and is generally used for the front wheels of sedans.

To put it simply, the main structure of MacPherson suspension is composed of coil springs and shock absorbers, which can avoid the phenomenon of forward, backward, left and right deviation of coil springs when stressed, limit the spring to vibrate in the up and down directions, and can use the stroke length and tightness of the shock absorber to set the softness and hardness of the suspension and performance.

Although the performance of MacPherson suspension in driving comfort is satisfactory, its structure is not large, which can effectively expand the riding space in the car, but also because its structure is straight, the impact in the left and right directions lacks blocking force, and the anti-braking nodding effect is poor.

MacPherson suspension was born out of the advent of front-engine, front-wheel drive (FF) models. FF models not only require the engine to be placed laterally, but also to add a gearbox, differential, drive mechanism, and steering gear, and the previous front suspension space had to be compressed and greatly removed, so engineers designed a space-saving, low-cost MacPherson suspension to meet the needs of the car. At present, the front and rear suspension of general sedans are basically MacPherson or its variants.

McPherson is a personal name. He was a native of Illinois, USA, and was born in 1891. After graduating from university, he worked in Europe for many years on aero engines before joining General Motors' engineering center in 1924.

In the 30s, GM's Chevrolet wanted to design a truly small car, and the chief designer was MacPherson. He was very interested in the design of a small sedan, with the goal of keeping the quality control of such a four-seater sedan within 0 9 tons, the wheelbase controlled within 2 74 meters, and the key to the design was the suspension. MacPherson changed the front suspension method of leaf springs and torsion bar springs that were prevalent at the time, and creatively combined shock absorbers and coil springs and mounted them on the front axle.

Practice has proved that this suspension form is simple in construction, takes up little space, and has good maneuverability. Later, MacPherson moved to Ford, and in 1950 Ford's subsidiary in the UK produced two cars, which were the first commercial cars in the world to use MacPherson suspension. Due to its simple structure and superior performance, MacPherson suspension is praised as a classic design by connoisseurs.

The MacPherson suspension is one of the most widely used front suspensions for sedans in the world today. MacPherson suspension consists of coil springs, shock absorbers, triangular swing arms, and most models also have a stabilizer bar. The main structure is simply that the coil spring is sleeved on the shock absorber, and the shock absorber can avoid the phenomenon of forward, backward, left and right deviation of the coil spring when stressed, limit the spring can only vibrate in the up and down directions, and can use the length of stroke and tightness of the shock absorber to set the softness and hardness of the suspension and performance.

The MacPherson suspension has a simple structure, so it is lightweight and responsive. And under the geometry of a rocker arm and struts, the camber angle of the wheel can be automatically adjusted, so that it can adapt to the road surface when cornering, so that the ground contact area of the tire is maximized, although the MacPherson suspension is not a high-tech suspension structure, but the performance of the MacPherson suspension in driving comfort is still satisfactory, but because its structure is straight, the impact of the left and right directions lacks blocking force, the anti-braking nodding effect is poor, the suspension rigidity is weak, the stability is poor, and the cornering roll is obvious.

Due to its small footprint, it is suitable for small cars and most medium-sized cars, and the common Guangzhou Honda Fit, Dongfeng Peugeot 307, FAW Toyota Corolla, Shanghai GM LaCrosse, FAW-Volkswagen Magotan and other front suspensions all use MacPherson independent suspension.

It should be noted that the Porsche 911, which is a supercar, also uses a MacPherson front suspension, which is enough to prove that this suspension has a wide range of adaptability.

Main advantages: simple structure, small footprint, fast response, low manufacturing cost.

Main disadvantages: small lateral stiffness, poor stability, large cornering roll.

Applicable models: small and medium-sized sedans, mid-to-low-end SUV front suspension.

The MacPherson type is a form of suspension consisting of a twisted strut and a lower wishbone, and the shock absorber can double as a steering kingpin, and the steering knuckle can rotate around it. It is characterized by the kingpin position and the front wheel alignment angle that changes with the up and down jumping of the wheel, this suspension structure is simple, the arrangement is compact, the front wheel alignment changes little, and it has good driving stability. Therefore, the most used independent suspension for sedans at present is the MacPherson suspension.

In order to reduce costs, low-end vehicles use integral axles and torsion beams for non-independent suspension.

The rear suspension of high-end cars is independent suspension, but MacPherson has poor stability, and if it is used on the rear wheels, the traction is poor, and the cornering is unstable.

Most of the independent rear suspension uses multi-link suspension.

A lot of it is in use.

Especially front-wheel drive and 4WD vehicles. Like Camry, Cerato, Aurora, Old Impreza, Antelope, etc., etc...

There are not many pure rear-wheel drive cars with this. It seems that the one I've seen is boxster cayman.,MR2.。。

MacPherson has nothing to say, the current car from Audi to Alto, the front suspension is used for this, mainly when one side of the tire off the ground, let the tire automatically enter the state of idling, and then let the engine's rotation force rotate when it hits the ground again, mainly to prevent when a wheel is off the ground, due to the power to give its power, when it hits the ground, the speed difference between the two wheels is too large, and the danger of control.

The main good or bad is to look at the rear suspension Now the mainstream of a torsion beam and a multi-link In fact, the torsion beam can only be regarded as a semi-independent suspension That is, there is a cross beam at the rear of the car And then the two ends of the beam Then connect the suspension system to connect the wheels Multi-link is a serious independent suspension The specific appearance can be seen in the suspension of F1 The general family car uses a torsion beam mainly because the space is relatively small Multi-link is generally used much in high-end cars Although it is good, but the point is also large The space is also large For example, the Fu hatchback From the outside, its internal space should be very large But this is not the case, the reason is that its rear suspension is multi-link, which can also show that multi-link is very space-consuming, and at the same time, it can also show that the stability and balance of multi-link suspension is also very strong, generally like Passat, Grand Hyatt and other commercial cars use this suspension method.

Hanging the microphone is to put you on the microphone so that your name is always displayed on the microphone, which is generally advertised.

The hanging microphone is connected to the microphone and keeps it all the time.

To be correct, it is MacPherson, its structure is simple, the cost is low, the load capacity is weak, and it is only suitable for the front suspension of the bottom car.

The rear suspension basically does not have a MacPherson suspension rear suspension, otherwise it is a multi-link? Independent suspension and semi-independent suspension of torsion beams because for cost control? The cost of independent suspension is higher, and basically semi-independent suspension is used [If you have a problem with the car, ask the car master.
