ABSTRACT
Transmission by the transmission and control mechanism, whose basic use is to change
the gear ratio, wheel torque and speed to expand the range to meet the constantly changing
driving conditions, while making the engine work in a favorable condition, a car assembly
an ponent parts. The structural requirements of the automobile transmission
of power, fuel economy, shift control of the reliability and portability, stability and
efficiency of transmission has a direct impact.
The subject of this design is the Austrian Teng pickup transmission design. Pickup based on
the basic parameters can be designed to meet the requirements of the intermediate shaft
manual transmission. Since the middle of transmission shaft is small, the principle is simple,
reliable, and easy manipulation, it is widely used in most cars. The design of the middle axis
five-speed manual transmission, its main purpose is based on mechanical principles,
mechanical design, AutoCAD and other skilled use of knowledge and mastery, while the
use of vehicle structure, automotive design, materials, mechanics and other disciplines of
knowledge, on the intermediate shaft Transmission of the parts design and assembly
drawing using AutoCAD software and part drawing. This paper will outline the status and
development trend of transmission; its working principle described, a reasonable choice of
transmission scheme design; to determine the file transmission gear ratio and parameters; on
