Effects of lug height on final gear ratio for a snowmobile....

Click For Summary
SUMMARY

Changing the lug height on a snowmobile track can influence the final drive ratio, particularly when considering different snow conditions. On hardpack surfaces, the effect is minimal, while in soft, fluffy snow, the change in effective drive force can vary significantly. The primary factor governing the final drive ratio remains the radius of the drive wheel, not the lug height or track thickness. Empirical testing, such as measuring speed over ground at a consistent engine RPM, is recommended to determine the actual impact of lug height on performance.

PREREQUISITES
  • Understanding of snowmobile mechanics and drive systems
  • Knowledge of traction dynamics in varying snow conditions
  • Familiarity with the concept of tangential velocity and its relation to gear ratios
  • Experience with empirical testing methods for vehicle performance analysis
NEXT STEPS
  • Research the impact of track thickness on snowmobile performance
  • Learn about the physics of traction and drive ratios in tracked vehicles
  • Explore methods for measuring vehicle speed and RPM correlation
  • Investigate the effects of different lug designs on snow traction
USEFUL FOR

Snowmobile enthusiasts, engineers involved in vehicle design, and anyone interested in optimizing snowmobile performance for various snow conditions.

There is no track flat on the ground between those two wheels and no indication of the thickness that such a track might have.

That's where the 'imagine' part of imagine comes into play.....:approve:

Statements of opinion about who is right or who is wrong are unhelpful.

Lol... well, "are unhelpful" is an opinion isn't it ?

Stay on track, now... don't derail ..... :oldgrumpy:
