哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計 摘 要 懸架是現(xiàn)代汽車上的重要總成之一，它最主要的功能是傳遞作用在車輪和車架(或車身)之間的一切力和力矩，并緩和汽車駛過不平路面時所產(chǎn)生的沖擊，衰減由此引起的承載系統(tǒng)的振動，以保證汽車的行駛平順性。為了迅速衰減不必要的振動，懸架中還必須包括阻尼元件，即減振器。此外，懸架中確保車輪與車架或車身之間所有力和力矩可靠傳遞并決定車輪相對于車架或車身的位移特性的連接裝置統(tǒng)稱為導(dǎo)向機構(gòu)。 此次設(shè)計是對哈飛路寶7110前獨立懸架設(shè)計，畢業(yè)設(shè)計要求根據(jù)夏利某改型車的改?？傮w方案要求，對其前懸架進(jìn)行設(shè)計計算。為了闡述懸架的設(shè)計過程，說明書分別從設(shè)計計算、仿真分析、優(yōu)化設(shè)計等方面對夏利用麥?zhǔn)綉壹艿脑O(shè)計過程進(jìn)行了介紹。說明書首先闡述了懸架中關(guān)鍵零部件如：螺旋彈簧、橫向穩(wěn)定桿、減振器等的設(shè)計、選型和校核 關(guān)鍵詞：麥弗遜獨立懸架；導(dǎo)向機構(gòu)；減震器；彈簧；橫向穩(wěn)定器 ABSTRACT Suspension is the modern car on the important assembly, which has one of the main function is to transfer function in the wheels and frame (or body) all between the force and moment, and ease when rough road surface cars driving by the impact of attenuation arising from the vibration of the bearing system, to ensure the smooth running of the car. So must the wheel and frame or body to provide flexible connection between, rely on the elastic element to deliver the wheel or axle and frame or between vertical load of the body, and depend on the deformation to absorb energy, to achieve the purpose of the buffer. This design is to LuBao hafei before 7110 independent suspension design, the graduation design requirements according to a car to retrofit of the entrant 。The overall design of request, to the front suspension design calculation. In order to this suspension design process, the specification separately from the design calculation, the simulation analysis, optimization design with wheat for supporters of suspension design process were introduced in this article. The first elaborated the suspension of the key parts such as: spiral spring, horizontal WenDingGan, shock absorber of such as design, selection and check Keywords: paper independent suspension; Steering mechanism; Shock absorber; Spring;Transverse stabilizer II
