Abstract
A synchronizer is a key component in automotive transmission. It is necessary to detect the matching quality between a synchronizer ring and cone. For this purpose, a friction torque based detection system of matching quality between a synchronizer ring and cone is designed in this paper. In the system, the acceptance criteria are established by the residual sum of squares (RSS), and the quality of the synchronizer is determined by measuring the friction torque and backup gap. This synchronizer ring and cone matching quality detection system has been implemented. The system is mainly used for quality detection of the synchronizer ring and cone in the automobile gearbox before packing. It improves the consistency of the synchronizer ring and synchronizer cone, which makes the synchronizer lighter and more reliable during shifting of the gearbox. According to market research, the system designed and implemented in this paper is advanced and original.
Highlights
The friction elements used in modern automotive transmission come in many forms, the performance of which has a direct influence on the power, economy, and reliability of cars [1]
The synchronizer relies on the friction cone between synchronizer ring and cone to synchronization
When there is a difference between rotational speeds of the friction cone surfaces, a friction torque is generated on the friction cone
Summary
The friction elements used in modern automotive transmission come in many forms, the performance of which has a direct influence on the power, economy, and reliability of cars [1]. Wear due toquality normalofuse changes synchronizer ring and cone to will ensure performance If they do not the fit well enough, it will affect the the coefficient of friction. Contact angle, the contact mode,quality and the average that radius of the friction surface This makes detecting the match a problem needs to be solved. 2, the theoretical of to themeet friction needs of industrial production, torque based detection systemcriteria for matching quality cone in the synchronization processaisfriction introduced. The the system is mainly lighter used forand quality synchronizer ring detection and synchronizer which makes synchronizer moredetection reliable of synchronizer and coneAccording in the current automobile gearbox before packing It implemented improves the during shifting ofring the gearbox. When there is a difference between rotational speeds of the friction cone surfaces, a friction torque is generated on the friction cone
