Take you to understand the frame and suspension of motorcycles and all terrain vehicles, so that you can no longer be a novice

When we discuss a car, we often discuss its power performance? How comfortable is it? Perhaps to put it more broadly, it's about discussing the personality of a car? In addition to engine power performance, the other most important factors are the suspension system and frame. Nowadays, major manufacturers such as Japan, Europe, and the United States, which dominate the automotive industry, have different views and design concepts on suspension systems and frames. Therefore, the vehicles produced by each manufacturer have vastly different personalities. In terms of suspension system, it not only affects the comfort of riding, but also causes differences in handling. However, what is comfort and what is handling? Firstly, it is necessary to explore the operating principle of the suspension system and the construction and performance of various suspensions.

What is the feeling of riding?

The so-called "sense of riding", simply put, is the "direct feeling that a car gives to the driver", or the "personality that a car shows". Although it is impossible for each driver to have exactly the same reaction to the same car, several more objective entry points can still be found to discuss a car. For example, comfort and handling. When it comes to comfort, many people may immediately come up with the image of riding an American cruiser smoothly on a wide road surface, which is the comfort we generally need. Furthermore, as long as the suspension of the vehicle can cushion the vibration and smoothly return to its original stable state when passing through potholes, making the rider feel relaxed and free from any excessive and uncomfortable swinging, it can be called good comfort. Generally speaking, the so-called "softer tuning" suspension can bring better comfort because a soft suspension can slowly absorb vibrations without causing severe shaking. Someone has also conducted such research, testing the most uncomfortable vibration frequencies felt by various parts of the human body, and attempting to avoid these vibration frequencies when designing vehicle suspension, which can cause discomfort to people. However, comfort can also be explained in this way as the ability to maintain the center of gravity of the vehicle and rider to continue moving smoothly under bumpy road conditions. In this way, a vehicle with excellent comfort must be able to quickly respond to the road surface when passing through uneven roads. When the tires enter the cavity, the shock absorber quickly extends to support the ground with the tires, still maintaining the center of gravity of the vehicle and rider at the same level, At the same time, it also maintains tire adhesion to the ground.

American cruisers often use soft tuning suspension settings

When it comes to handling, many people immediately think about the cornering performance of a vehicle and whether it can smoothly turn. However, the handling referred to here refers to "whether the vehicle can respond immediately and satisfactorily to the operation of the rider." For example, before a vehicle makes a turn, the rider must reverse the steering wheel to change the vehicle's straight state and start tipping over the corner. The so-called handling can be seen here, If a car can immediately respond to a rider's reverse steering action by tipping over, we would call its handling sharp, as is typical of sports cars. On the other hand, if a car responds slowly and sluggishly to the operation of a rider, we would call it its handling ability
