Abstract

In this work, a linear position sensor module with a Hall Effect element for gear position sensing within a truck transmission is presented. The work involves the design of position sensor module structure, computer modeling of sensor performance, fabrication of sensor prototype, and prototype testing and characterization. The significance of the work is that a low cost linear position sensor module has been developed with high linearity for use in truck transmission for gear position sensing.

A smarter sensor design isn't just about optimizing sensing precision and dynamic performance. In many manufacturing environments, product durability and reliability under harsh conditions, is just as important. There is no glory for the world's most productive machine if it doesn't run nearly 100% of the time. Therefore, when it comes to dealing with extreme environmental conditions, smarter sensors are expected to be precise, accurate, cost effective and long lasting. For this project, the Hall Effect technology has been explored and custom fitted with appropriate electronics to meet the wide requirement profile of a truck transmission. The performance characteristics of linear Hall Effect sensors for non-contact determination of the position of a moveable permanent magnet along a pre-established path are analyzed. The complete sensor system is designed for ease of manufacturing and application in the harsh transmission environments.
