| Working principle | Shock absorbers are used to suppress vibrations as the spring bounces back after absorbing vibrations and shocks from the road. It is widely used in automobile to accelerate and attenuate the vibration of frame and body, and improve the driving comfort of automobile. When passing through the uneven road surface, although the shock absorber spring can filter the vibration of the road surface, the spring itself can be reciprocated, and the shock absorber is used to constrain the spring's beating. Then, the car editor patiently introduced the principle of the car shock absorber to his friends. The working principle of the shock absorber: Introduction In the suspension system, the elastic element is affected and vibrates. In order to improve the riding comfort of the car, the shock absorber is installed parallel to the elastic element in the suspension. In order to attenuate vibration, most of the shock absorbers used in automotive suspension systems are hydraulic shock absorbers |
| Effect | 1. Hang the cab, withstand the mass of the cab, and guide the vertical movement. The cab shock absorber can make the vehicle run smoothly, it can cushion the shock. 2. Ensure that the driver can feel the road conditions, which can make the vehicle run smoothly, and it can buffer the vibration. If there are no shock absorbers in the suspension, the car will not run smoothly, it will shake. 3. Optimize driving comfort, isolate or reduce vibration and noise. 4. Improve safety, withstand large impact and absorb collision energy. 5. Allow the cab to have a certain tilt. 6. Now many cab shock absorbers are hydraulic shock absorbers. The principle is that a cylinder with a small hole and a piston is filled with pressure oil, and when the spring vibrates, the oil is forced through the hole, thus limiting the effect. 7. The diameter of the hole determines the effect of the restriction. If the diameter of the hole is smaller, there will be a strong constraint, and the stability of the car is higher; On the contrary, a car ride is more comfortable. When designing, the diameter of the small hole should take into account stability and comfort. The cab suspension generally includes a separate front cab suspension and a rear cab suspension. Each cab mount section includes an elastic element (to withstand vertical loads and mitigate road impact), a damping device (to accelerate vibration attenuation), and a guide mechanism (to reduce cab roll during cornering). |
We can see the following three cab shock absorption methods:
One is the helical spring with the cab shock absorber: The helical spring, as an elastic element, is the common way of damping the cab at present. Low cost and acceptable damping effect. However, due to the long service life of some vehicles or the poor quality of the shock absorber spring, the rear suspension of the cab is likely to collapse, resulting in the phenomenon of the front of the vehicle. In addition, on off-road trucks, coil springs are a better choice. Because it is often driven in the field, the vehicle will also experience severe bumps, especially in some extreme cases, such as the case of the vehicle in the air, and the shock absorption of the cab is also a great test. If the airbag shock absorption is used, it is easy to cause the airbag burst in this case.
The second is the shock absorber: This design is common in the 1980s and 1990s Mercedes-Benz trucks, the use of independent shock absorber to achieve the effect of cab shock absorption, and now it is rarely seen.
The third is the air suspension: due to the use of air bag shock absorption, road turbulence can be well absorbed by the air suspension, and its shock absorption effect is good at present. However, in some domestic cars, the design distance between the rear cab air bag and the engine exhaust pipe is too close, and the air bag is easy to contact the high-temperature exhaust pipe on the bumpy road, causing the air bag to burst
