HFC1060D1輕型載貨汽車領(lǐng)從蹄式鼓式制動(dòng)系統(tǒng)設(shè)計(jì)-貨車制動(dòng)器含開題及4張CAD圖,HFC1060D1,輕型,載貨,汽車,蹄式鼓式,制動(dòng),系統(tǒng),設(shè)計(jì),貨車,制動(dòng)器,開題,CAD 輕型載貨汽車設(shè)計(jì)（制動(dòng)系設(shè)計(jì)） 摘 要 制動(dòng)系至少有兩套制動(dòng)裝置即行車制動(dòng)裝置和駐車制動(dòng)裝置。行車制動(dòng)裝置是用作強(qiáng)制行駛中的汽車減速或停車，并使汽車在下坡時(shí)保持適當(dāng)?shù)姆€(wěn)定車速。駐車制動(dòng)裝置是用作是汽車停在原地或坡道上。 本設(shè)計(jì)對(duì)鼓式制動(dòng)器的結(jié)構(gòu)形式進(jìn)行綜合的分析，對(duì)六種形式的優(yōu)缺點(diǎn)作了比較，根據(jù)對(duì)各種制動(dòng)器方案對(duì)比分析，本設(shè)計(jì)采用了領(lǐng)從蹄式制動(dòng)器。其主要優(yōu)點(diǎn)是：制動(dòng)器的效能及穩(wěn)定性均處于中等水平，但由于其在汽車前進(jìn)與倒退時(shí)的制動(dòng)性能不變，且結(jié)構(gòu)簡(jiǎn)單，造價(jià)較低，也便于附裝駐車驅(qū)動(dòng)機(jī)構(gòu)；易于調(diào)整蹄片與制動(dòng)鼓之間的間隙。本次設(shè)計(jì)中，行車制動(dòng)系采用人力液壓式制動(dòng)；駐車制動(dòng)的驅(qū)動(dòng)機(jī)構(gòu)為手動(dòng)駐車；串聯(lián)雙腔制動(dòng)主缸，雙回路結(jié)構(gòu)。前后制動(dòng)器都采用領(lǐng)從蹄式鼓式制動(dòng)器。設(shè)計(jì)中根據(jù)總體參數(shù)和制動(dòng)器的結(jié)構(gòu)與參數(shù)，通過理論推導(dǎo)和計(jì)算，對(duì)該車制動(dòng)時(shí)的制動(dòng)力和制動(dòng)力矩等做了細(xì)致的分析。 關(guān)鍵詞：制動(dòng)系統(tǒng)，制動(dòng)器，行車制動(dòng)系，應(yīng)急制動(dòng) LIGHT TRUCK DESIGN （BRAKE SYSTEM） ABSTRACT Break system consists of service break arrangement and parking break arangment. Service break system used to force the vehicle to show down and keep a steady speed when downgrading. The parking break system intended to hold the vehicle immovable when parked on an incline. This design carries on the synthesis analysis to the drum type of the brake structural style. It compares the advantages and disadvantages of six kinds of forms, and according to this contrast analysis of the kinds of the brake plan, the horseshoe type’s brake is adopted. Its main merits are that although the brake efficiency and the stability are in the medium level, because the automobile braking performance is invariable when going ahead and going backwards, the construction cost is lower, and it attaches installs in the vehicle’s driving mechanism and adjusts the gap between the brake shoe patch and the brake drum easily. The design uses manual hydraulic break and series connected double cavity general pump. Both the front and rear break is double leading-rear break. According to the vehicle’s parameters and the break’s parameter, after theory analytic and calculating, we analyzed the breaking force and direction stability when breaking specifically.
