摘 要
變速器用來(lái)改變發(fā)動(dòng)機(jī)傳到驅(qū)動(dòng)輪上的轉(zhuǎn)矩和轉(zhuǎn)速,目的是在原地起步、爬坡、轉(zhuǎn)彎、加速等各種行駛工況下,使汽車獲得不同的牽引力和速度,同時(shí)使發(fā)動(dòng)機(jī)在最有利的工況范圍內(nèi)工作。機(jī)械式手動(dòng)變速器是傳統(tǒng)的汽車傳動(dòng)系統(tǒng),由于其結(jié)構(gòu)簡(jiǎn)單、體積小、制造成本低、便于裝配和修理,傳動(dòng)效率高等優(yōu)點(diǎn),一直沿用至今。變速器的性能直接體現(xiàn)出整車性能的高低,特別是燃油經(jīng)濟(jì)性的好壞。所以變速器的設(shè)計(jì)質(zhì)量的高低一直是汽車行業(yè)競(jìng)爭(zhēng)的焦點(diǎn)。
隨著汽車工業(yè)的發(fā)展,轎車變速器的設(shè)計(jì)趨勢(shì)為增大變速器傳遞功率與重量之比,并要求變速器具有較小的尺寸和良好性能。在給定發(fā)動(dòng)機(jī)輸出轉(zhuǎn)矩、轉(zhuǎn)速及最高車速、最大爬坡度等條件下,著重對(duì)變速器齒輪的結(jié)構(gòu)參數(shù)、軸的結(jié)構(gòu)尺寸等進(jìn)行設(shè)計(jì)計(jì)算。

ABSTRACT
The transmission is been used to transform an engine to spread to drive the torque and the revolving speed on the wheel, the purpose is an earth to start and climb various condition that drove works, such as ascent, turn and acceleration...etc. at first down,make different travtive force of autocar acquisition and velocity, make the engine work in the most beneficial work condition range at the same time. Mechanical transmission is a traditional manual transmission car, because of its simple structure, small size, low manufacturing cost, ease of assembly and repair, high transmission efficiency, are still in use. Transmission performance of the vehicle directly reflects the level of performance, especially fuel economy is good or bad. Therefore, the design of transmission quality has been the focus of competition in the automotive industry.
Along with the development of the automobile industry ,the trend of car transmission designing is to increase it stransmission power and decrese its weight ,and hope have smaller size and excellent performance. In conditions that knowing the engine output torque , speed of engine and maximum speed of vehicles , maximum degree , focus on the designing of transmission gear structural parameters , axis geometry design computation ; as well as the transmission and drive program structure design
Key words :Transmission ;Gear ; Synchrotron ;Design
