Need help regarding automatic transmission

Click For Summary

Discussion Overview

The discussion revolves around automatic transmission, including its basic concepts and a comparison with manual transmission. Participants seek resources and insights for preparing presentations on the topic.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant requests help in collecting articles related to automatic transmission and its comparison with manual transmission.
  • Another participant provides a link to a website as a starting resource for understanding automatic transmission.
  • A different participant asks for guidance on preparing a PowerPoint presentation about automatic transmission, inquiring about what content should be included.
  • One participant mentions a discussion on continuously variable transmissions (CVTs), noting that their efficiencies are generally lower than those of manual transmissions, with specific efficiency figures provided. They also point out that if a CVT requires water cooling, it may indicate lower efficiency compared to manual transmissions.

Areas of Agreement / Disagreement

Participants express varying needs for information and resources, but there is no consensus on specific aspects of automatic transmission or its comparison with manual transmission.

Contextual Notes

Some claims regarding the efficiency of CVTs versus manual transmissions depend on proprietary information from manufacturers, which is not disclosed. There may also be assumptions about the conditions under which these efficiencies are measured.

Who May Find This Useful

Individuals interested in automotive engineering, students preparing presentations on transmission systems, and those seeking to understand the differences between automatic and manual transmissions.

hiiii...
i needed some help in collecting some articles related to automatic transmission...i need the basic idea of it,and comparison with manual transmission...
 
Engineering news on Phys.org
can i have a basic idea of preparing ppt about automatic transmission...what an all should be included in it
 
The following website has a good discussion of the various types of continuusly variable transmissions (CVTs)
http://en.wikipedia.org/wiki/Continu...e_transmission
None of the CVTs have efficiencies as high as manual transmissions: about 96% in all but the 1:1 gear which is about 98%. Manufactirers of CVTs will not disclose the efficiencies of their designs; it is proprietary.

Note that manual transmissions in standard automobiles do not require water cooling. If a particular CVT requires water cooling, that is proof that it is less efficient than a manual transmission.
