辛普森變速器結(jié)構(gòu)設(shè)計(jì)

摘　　要

目前，自動(dòng)變速器在汽車領(lǐng)域的應(yīng)用越來越廣泛。其中主要原因是自動(dòng)變速器能夠根據(jù)路面狀況自動(dòng)改變車速，這極大地方便了駕駛者。不僅能夠緩解駕駛者駕駛疲勞減少路面交通事故，而且還能夠提高汽車的燃油經(jīng)濟(jì)性。同時(shí)，還能提高汽車的動(dòng)力性。行星齒輪變速箱主要結(jié)構(gòu)為行星齒輪機(jī)構(gòu)，行星齒輪機(jī)構(gòu)主要由太陽輪、外齒圈、行星輪、行星架組成。由于行星齒輪機(jī)構(gòu)具有兩個(gè)自由度，因此行星齒輪機(jī)構(gòu)沒有固定的的傳動(dòng)比，不能直接應(yīng)用于變速器。為了能夠?qū)⑿行驱X輪變速器應(yīng)用于自動(dòng)變速器，必須將齒輪機(jī)構(gòu)中的元件固定使其具有一個(gè)自由度。只有一個(gè)自由度的行星齒輪機(jī)構(gòu)具有固定的傳動(dòng)比，因此可以應(yīng)用于自動(dòng)變速器中。我設(shè)計(jì)的為商務(wù)車行星齒輪變速箱，行星齒輪機(jī)構(gòu)具有結(jié)構(gòu)緊湊、剛度大、傳動(dòng)平穩(wěn)等優(yōu)點(diǎn)。行星齒輪變速箱動(dòng)力改變由液力變矩器進(jìn)行控制，其操縱機(jī)構(gòu)為離合器和制動(dòng)器，并通過液壓油進(jìn)行控制，從而實(shí)現(xiàn)自動(dòng)換擋。但是，自動(dòng)變速器結(jié)構(gòu)比較復(fù)雜。通過這次畢業(yè)設(shè)計(jì)我對(duì)自動(dòng)變速器原理做了大量的工作并參考商務(wù)車車型最終確定了其傳動(dòng)方案，并對(duì)各檔傳動(dòng)比做了詳細(xì)的說明。

Abstract

At present, more and more widely applied in the field of automatic transmission in car.The main reason is that automatic transmission can change the speed automatically according to the road conditions, it has made great drivers.Not only can alleviate drivers driving fatigue reduce road traffic accidents, but also can improve the fuel economy of the car.At the same time, it can improve power performance of car.Planetary gear transmission main structure for a planet gear mechanism, the planetary gear mechanism is mainly composed of the sun wheel, outer ring gear, planetary wheel, planet carrier.Because the planet gear mechanism has two degrees of freedom, so the planet gear mechanism has no fixed transmission ratio, cannot be directly applied to the transmission.In order to be able to will be applied in the automatic transmission planetary gear transmission, the gear mechanism of components must be fixed exhibit a degree of freedom.There is only one degree of freedom of planet gear mechanism has a fixed ratio, thus can be used in the automatic transmission.I design for commercial vehicles planetary gear transmission, the planet gear mechanism has the advantages of compact structure, large rigidity, smooth transmission.Planetary gear transmission power changes controlled by hydraulic torque converter, its operating mechanism for the clutch and brake, and the control with the hydraulic oil, so as to realize automatic shift.However, the automatic transmission structure is more complex.Through this graduation design I made a lot of work on automatic transmission principle and refer to commercial vehicles models ultimately determine the transmission scheme, and has made the detailed instructions for each transmission ratio.
