Many group members will consider one thing when buying a car: whether the suspension on the car is independent or non-independent. Of course, the non-independent suspension is more advanced and the ride comfort is better. The most advanced ones are air suspension and electromagnetic suspension. Do you know which suspension is the most shocking?
Dependent and independent suspension
Here we incidentally mention these two suspension methods that we are most familiar with. Independence and independence. As the name suggests, independent suspension means that a single wheel has its own independent set of systems. Its beating will basically not affect the operation of the other three wheels. The comfort is better, so it is the mainstream equipment in mid-to-high-end cars. .
Instead of being independent, it is a set of wheels, such as two front wheels, or a connecting bar between the two rear wheels. The structure is simpler, the cost is lower, and it is generally used in low-cost vehicles.
Air suspension
Air suspension is generally used on medium and large luxury car bodies.Both the comfort of a car and the passing performance of off-road vehicles must be taken into account. The air suspension system is the best choice to achieve this goal, depending on the road conditions and distance.sensorSignal, the trip computer will determine the height change of the vehicle, and then control the aircompressorAnd the exhaust valve, the spring is automatically compressed or extended, thereby reducing or increasing the ground clearance of the chassis, so as to increase the stability of the high-speed

In other words, the computer injects or releases air into special springs as needed to adjust the height and softness of the vehicle. It is of great significance for off-road vehicles, and it is very common in luxury SUVs. The disadvantage is that reliability and durability need to be studied.
Electromagnetic suspension
Magnetic Ride Control (Magnetic Ride Control) is a new type of independent suspension system that uses electromagnetic response, and is the main research direction of future suspension. It can respond to road conditions within 1 millisecond, suppress vibration, and keep the body stable. The electromagnetic suspension soldier thinks that there are three representative price comparisons: Cadillac,Benz, BOSE.
#卡迪拉克的MRC Suspension#
When the vehicle is driving on a rough and uneven road, the wheel displacementsensorIt will detect the road surface at a frequency of up to 1000 times per second, and transmit the signal to the on-board control system in real time. The control system is based on the Skyhook algorithm. The larger the magnetic field, the greater the damping.
The current electromagnetic suspension is still in the preliminary stage of research.But it still achieved good results in Cadillac, such asbrakeThe nodding phenomenon has been significantly alleviated, and there is also good support when making sharp turns. Electromagnetic suspension is equipped on the high-end models of ATS and XTS. If you like it, you can pay attention to it.
#Mercedes-Benz MBC Magic Body#
I believe that many of my friends must have heard of "Mercedes-Benz Magic Body". What is the specific effect? Let's take a look at the following video!
The Mercedes-Benz Magic Body Control system can scan the road ahead and make corresponding adjustments to driving comfort.Two installed on the front windshieldCameraTo monitor the condition of the road in real time, it can detect a distance of about 0.5 meters to 1.4 meters ahead, and the maximum accuracy can detect fluctuations of 1 to 2 cm.
This should be regarded as the most advanced suspension system available on the market, and it is currently only available on the highest equipped models such as Mercedes-Benz S600 and S65. However, there is still a contradiction at present. Because the calculation speed of the computer is still limited, it takes a certain reaction time to adjust the suspension. Once you run faster, this shock absorption effect becomes less obvious.
#BOSE磁吊#
Yes, you heard it right, just doCar stereoThe big brand: BOSE. Not only do they play stereos, but their knowledge in suspension is also amazing. If you don’t believe me, take a look at this video:
BOSE suspension system has four key technologies: linear electromagnetic induction motor, power amplifier, control algorithm and calculation speed. Through BOSE's unique power amplifier, the control signal for adjusting each wheel is amplified into a current enough to drive the motor to drive the electromagnetic linear motor to work and extend or compress the suspension.
Its uniqueness is that it can not only servemotorProvide electric current, and electric current can also be generated by the motor, which forms a set of electric power compensation mechanism.
For example, when a wheel presses through a pit, the suspension on one side will stretch and the suspension on the other side will be compressed. The motor on the side extends the suspension. Such a self-compensation system saves about 1/3 of the power compared to a conventional regulation system.
Technology changes lives. The benefit of this technological advancement is that in the future, ordinary people can enjoy better technology at lower prices.If in the future ourcarWe no longer use the most basic methods of independence and non-independence, but adopt adaptively adjustable electromagnetic suspension. How comfortable will our travel become? Really is a good expectation.
