(THE GENERAL DESIGHN OF TRANSMISSION)
ABSTRACT
Car birthed in 19th century, and today it has a history of more than 100 years, during the period, the automobile industry has developed with amazing speed, and written an important chapter in the modern human civilization. Car for the development of the world economy and human life have access to modern Immeasurable tremendous impact. At present, there are hundreds of millions of cars on land in the world, and grow in a speed of ten millions per year. We can assert that there are no mechanical products more than cars so extensive and profound influence to the human. Have made an indelible contribution for the progress of human society.
Transmission as an important component of car is used to change the engine reached the powerwheele’s torque and rotational speed, in order to get different power and speed in start, climbing, turning, accelerating, and other case of travel.
Transmission has two styles of mechanical manule transmission and mechanical devices continues transmission, if the transmission’s shift more its power and economic was guaranteed, if fewer its manipulation is convenience, this design I design an heavy truck transmission, this design I determined the peed ratio after careful analys of peed ratio and ultimately the relevant type of the car, I made a careful analysis of the layout of the drive agency programmers against the transmission and finally use the 5+1 block intermediate transmission, the form of shift use a synchronous device. After requested the overall the form of agencies use direct manipulation institutional forms. This designed of transmission meet the dynamic of the necessary power also meet its economic targets. Final adoption the degree of gear, axle, keys, bearings, etc. the size of transmission and strength of components are designed to meet the requirements.
The development trend of the transmission is more complex, more and more is also high automation degree, automatic transmission is the mainstream of the future.
KEY WORDS: Transmission, Design, Heavy truck, Speed ratio.
