Title: A novel mechanism to engage gears in motion
Inventor: RANADE NITIN SHANKAR
Filed: 2010-04-21
Abstract: The invention comprises a reverse gear engagement mechanism that engages reverse gear effectively and while minimizing the reverse gear wear and tear and the noise level. It works by reducing the speed of reverse idler gear to a level required for reverse gear engagement, before engaging with the idler fixed gear. The invention can be installed on new and existing automobiles that have manual gearboxes. The mechanism used for the speed reduction comprises specially designed and located friction elements that reduce the speeds of axial and rotational motions of the idler reverse gear. The axial and rotational speeds are reduced to a range where the idler reverse gear engages with the fixed reverse gear smoothly, thereby causing minimal noise and wear and tear of the engaging parts.
