Research Of Single-axle Screwing Machine Of Automobile Rear Axle

The paper lists four methods of controlling torque according to how to control the torque of the automobile final drive of rear axle's main gear. It analyses mechanics respectively. It analyses merits and flaws of each method of controlling torque. Direct controlling torque is selected on this paper on the basis of analysis.The paper first does mechanical design works according to the characters and process-demand of the product screwed. At the same time, it discusses the operating principle of parts. The machine can meet the demand of strength unloaded and screwing process. Then we design I/O circuit, direct current circuit and motor-control circuit with operating movement of the machine. Finally ,we realize to call interface function of multi-function card by DLL. The paper discusses how the software modal is divided and realized in detail. Some succinct interfaces are showed on the paper too.
