哈弗H6变速器设计(含CAD零件图装配图)(任务书,开题报告,文献摘要,外文翻译,论文说明书12000字,CAD图12张)
摘要
变速器是汽车上很重要的一部分,变速器可以改变发动机的转矩和转速,使汽车在任意时间都获得最合适的牵引力和速度。变速器也可以通过倒档改变汽车的行驶方向以满足倒车的行驶要求。变速器在近年有了飞速发展,涌现出许多先进的变速器如液力自动变速器(AT)、电控机械式自动变速器(AMT)、双离合式自动变速器(DCT)、机械无级式变速器(CVT)。虽然现在自动变速器很流行,但是从市场的需求来说,手动变速器仍然是必不可少的存在。变速器按照不同的分类方法可以分为两轴式,三轴式变速器;手动变速器,自动变速器。本设计课题是对哈弗h6三轴六挡手动变速器进行设计,通过根据车型的具体参数进行齿轮的设计并进行校核,轴的设计并进行校核;轴承的设计并进行校核。

Abstract
The transmission is a very important part of the car, the transmission can change the engine torque and speed, so that the car at any time to get the most appropriate traction and speed. The transmission can also change the direction of the car by reverse to meet the reversing travel requirements. In recent years, transmissions have developed rapidly, with many advanced transmissions such as hydraulic automatic transmission (AT), electronic control mechanical automatic transmission (AMT), dual clutch automatic transmission (DCT), mechanical continuously variable transmission (CVT). Although the automatic transmission is very popular now, but from the market demand, the manual transmission is still essential to exist. Transmission can be divided into different types by using different classification methods. They are two-axis, three-axis transmission; manual transmission, automatic transmission. The project of my design is the Haver h6 three-axis six-speed manual transmission design. According to the specific parameters of the vehicle ,I design the gear and shaft then check ; bearing selection and check.
Key words:gear, three - six - speed transmission, shaft, bearing
