Before you can understand how a car shock absorber works, you should also understand all of the parts of the suspension system and how they work together to ensure safe vehicle operation. Then you will be better able to understand the role that the car shock absorber plays in this process. A car's suspension system consists of several parts and helps a driver to control the vehicle. The suspension system increases friction between the road and the car's tires, makes passengers more comfortable inside the car, and give the car stability when it's being handled by a driver. The car's suspension system consists springs, anti-sway bars, and dampers. The springs in a suspension system can be coil springs, leaf springs, air springs, or torsion bars. Dampers are any component of the suspension system that dampen and absorb shock. One of these components is the car shock absorber. Without dampers in place, all of the energy absorbed by the springs in the suspension system would be released without any sort of control. This would make riding in a car or other vehicle extremely bumpy and uncomfortable for the driver and passengers. The car shock absorber controls the motion of the springs by dampening the shock. This is accomplished by cutting down on the vibrations that are made when the car hits a bump or another type of shock happens. The shock absorber has two mounts, the upper mount and the lower mount. The upper mount of the car shock absorber is attached to the frame and the lower mount is attached to the axle. When your car hits a bump, the car shock absorber dampens the shock through a simple process. The spring's energy is transferred from the car shock absorber into the piston. Fluid is allowed to leak as the piston moves up and down. The release of fluid slows the piston down, which results in a slowing down of the spring's movement. Most car shock absorbers rely on fluid friction as described above, but there are also several other types of shock absorbers available for vehicles. Pneumatic systems can be used where the compression of gas dampens the shock to the vehicle and reduces the spring's movement. Magnetic dampers are used in some vehicles, but this is not a widely used shock absorption method. Many people think that it is okay to drive with a damaged car shock absorber since it just dampens the shocks received while driving. However, this assumption is incorrect. Shock absorbers have important functions related to safety including controlling rolling and swaying of the vehicle. In addition, shock absorption can help protect other parts of the vehicle, reducing damages and cutting repair costs. If you suspect your car shock absorber is damaged, take your car to a mechanic and have it checked out as soon as possible. Your mechanic will be able to tell you if your vehicle needs a new car shock absorber or if other repairs need to be made. Your car shock absorber should be replaced from time to time for maximum vehicle performance. There are many ways that replacing your car shock absorber can help your car perform better. Handling of the car will be more consistent, as will braking the vehicle. Your spring and suspension movement will also be better controlled. Other benefits include prevention of early tire wear, reduction of wear and tear on other parts of your car, and keeping the wheels aligned properly. Most modern car owners usually feel very comfortable with their car. Their car may drive smoothly on various kinds of road surfaces leaving the passengers to feel pretty comfortable. But do they realise that they may lose such comfort if they don't take care of the shock absorbers? This is exactly why car owners are supposed to know the odds and ends of their shock absorbers. What are shock absorbers? Car owners need to know that shock absorbers - as its name implies - are the component of their cars that are assigned the task of minimising excessive motion that the car receives due to uneven road surfaces. How do shock absorbers work? Every single time a driver hits a bump or knocks over a hole on the road, these particular components try their best in order to absorb the oscillation due to the motion that takes place when car springs move upwards and downwards. In order to do this, the shock absorbers enforce a piston through oil so as to develop the required hydraulic friction. This is meant to eliminate the excessive suspension motion.There are 2 ways in which shock absorbers work. The first is the one known as compression or the closing motion. Another one is the rebound or what is also known as the opening motion. It is by these 2 ways that shock absorbers are able to maintain the contact of the tyres with the surface of the road.Types of shock absorbers availableThere are various types of shock absorbers available, each serving a different kind of purpose. 1. Air shock absorbers Also sometimes called a load-adjustable shock absorber. Air shock absorbers use compressed air to make the absorber stiffer. Compressed air is also used for the spring of the absorber. Loading more air will make the air shock absorber stiffer while removing air will make it less stiff. 2. Damper shock absorbers Commonly called dampers, this particular shock absorber is designed for smooth deceleration for the vehicle, and comes in two variations: fluid or mechanical.Fluid dampers lessen the shock to a vehicle through the use of compressed fluids, while mechanical dampers mimics the fluid design, but uses electric signals instead of just a fluid substance. 3. Shocks with reservoirs Shocks with reservoirs, or reservoir shocks, are commonly used for off-road vehicles. Reservoir shocks uses nitrogen as an absorbing material, as their primary purpose is to improve bounciness when the vehicle is travelling through rough and bumpy surfaces. 4. Spring Shock AbsorberThe most basic and commonly used shock absorber is the spring shock absorber. As its name suggests, it uses a rubber or elastic spring that can compress or expand when needed. How durable are shock absorbers? Unfortunately, it is often the case that most of the shock absorbers available in the market are relatively vulnerable to damages. This is especially true if the car's suspension system is often forced to work under extreme temperatures. Yet, at this point of time, car owners may be asking how they are supposed to know if their shock absorbers need to be replaced. Well, the easiest way car owners can approach is to drive their car to the nearest uneven roads that have lots of bumps or holes.It is also important to keep in mind that even though oil leakage coming out of the shock absorbers are obvious indicator for replacement, there is a tendency for some to wear out even without the least amount of oil leakage.Yet, it is also necessary for car owners to pay careful attention to any signs of dents visible on the body of the shock absorbers, ragged bushes, tiny holes visible in piston rod and also abnormal tyre conditions. Shock wear indicator Car owners also need to know how long shock absorbers have been in use so as to anticipate for possible damages or needs of replacement. Some car owners make use of the count on mileage number as the indicator. Unfortunately, car mileage alone is not reliable enough. The reason is because there are shock absorbers that still work under excellent condition after having reached more than sixty-five thousand kilometres while some others wear out before even reaching thirty thousand kilometres.It is also wise to perform a conventional bumper bounce test. This usually helps to ensure car owners whether or not their shock absorbers require a replacement.Last but not least, another thing that car owners often misunderstand for shock wear indicator is the warranty offered by the dealers. Warranties are often meant to raise the sale value of the shock absorbers without necessarily indicating how long they have been in use. Even though warranty might free car owners from the replacement cost, it seldom offers free labour costs.A shock absorber is a suspension component that controls the up-and-down motion of the vehicle’s wheels. Though the devices are called shock absorbers, the job of absorbing the jolts that result when the wheels pass over bumps or dips is handled mostly by the springs. Shock absorbers would more accurately be named dampers, as they are called in the United Kingdom. Their main job is to damp the motion mentioned above, keeping the vehicle’s body from bouncing down the road on its springs. In fact, the simplest shock absorber test is to push down on the vehicle’s bumper; a healthy shock absorber or MacPherson strut will allow the body to rebound but quickly come to rest. If the vehicle goes into a prolonged bounce cycle, the shock needs to be replaced. Bad shocks or struts aren’t safe because they fail to maximize tire contact with the road, which degrades handling and braking. Each shock absorber contains a piston that slides through a cylinder. Hydraulic fluid on either side of the piston head provides the resistance against which the up-and-down motion of the wheels must work as it compresses and expands the shock absorber. A valve in the piston head, and typically another at the base of the cylinder, allow the fluid, or oil, to flow through as the unit expands and compresses. But when the compression is faster or greater, the oil can’t squeeze through the valve fast enough, and it becomes pressurized. The more the oil is pressurized, the more it resists the piston’s motion. The size of the valve aperture helps determine the shock absorber’s rate — how firm or soft it is. Firmer shock absorbers make for a harsher ride but may improve handling and help to minimize body roll. There are variable-rate shock absorbers — both manual and electronically controlled. The manual ones have a setting that the owner or a mechanic can adjust. Electronically controlled types are the key to adaptive suspensions, the most sophisticated of which are computerized to vary individual shock firmness many times per second in response to conditions. 課題名稱 可控并聯(lián)雙筒式減振器設(shè)計 課題來源 基金項目 課題類型 AY 指導(dǎo)教師 肖艷秋 學(xué)生姓名 師國賓 學(xué) 號 200802010431 專 業(yè) 機(jī)械設(shè)計制造及其自動化 減震器是改善汽車平順性的最好途徑，它是安裝在車體與負(fù)重輪之間的一個阻尼元件，其作用是衰減車體的振動并阻止共振情況下車體振幅的無限增大，能減小車體振動的振幅和振動次數(shù)，因而能延長彈性元件的疲勞壽命和提高人乘車的舒適性。 調(diào)研材料的準(zhǔn)備：查閱《汽車?yán)碚摗?，《汽車底盤構(gòu)造》，《汽車設(shè)計課程設(shè)計指導(dǎo)書》等相關(guān)書籍，以及從網(wǎng)上瀏覽下載的一些畢業(yè)設(shè)計方面的資料。 設(shè)計目的：畢業(yè)設(shè)計是教學(xué)過程的最后階段采用的一種總結(jié)性的實踐教學(xué)環(huán)節(jié)。通過畢業(yè)設(shè)計，能使學(xué)生綜合應(yīng)用所學(xué)的各種理論知識和技能，進(jìn)行全面、系統(tǒng)、嚴(yán)格的技術(shù)及基本能力的練習(xí)。它可以總結(jié)檢查學(xué)生在校期間的學(xué)習(xí)成果，是評定畢業(yè)成績的重要依據(jù)；同時通過畢業(yè)設(shè)計，也使學(xué)生對某一課題作專門深入系統(tǒng)的研究，鞏固、擴(kuò)大、加深已有知識，培養(yǎng)綜合運(yùn)用已有知識獨立解決問題的能力 要求： （1） 要求一定要有結(jié)合實際的某項具體項目的設(shè)計或?qū)δ尘唧w課 題進(jìn)行有獨立見解的論證，并要求技術(shù)含量較高； 　　 (2） 設(shè)計或論文應(yīng)該在計劃所規(guī)定的時限內(nèi)完成； 　 (3） 書面材料：框架及字?jǐn)?shù)應(yīng)符合規(guī)定。。 設(shè)計思路與預(yù)期成果：根據(jù)相關(guān)資料，運(yùn)用相關(guān)專業(yè)知識進(jìn)行合理的假設(shè)與計算研究，最后成果要滿足減振器的一般性能要求，且完成設(shè)計的主要內(nèi)容。 時間安排： 第1-3周：查閱相關(guān)資料，整體上了解畢業(yè)設(shè)計。 第4周：完成開題報告及其文獻(xiàn)綜述。 第5-10周：減振器設(shè)計方案分析及各種參數(shù)的計算 第10-11周：校核設(shè)計方案的部件。 第11-13周:繪制總裝配圖和組件圖。 第14周:手工繪制裝配圖。 第15-17周:整理書寫設(shè)計說明書。 第18周:準(zhǔn)備答辯。 指導(dǎo)教師簽名： 日期： 鄭州輕工業(yè)學(xué)院畢業(yè)設(shè)計（論文）開題報告
