TVS Motors patent semi-AMT technology for two-wheeler

TVS Motor Company has been granted patent for a gearshift assembly that promotes Semi AMT for motorcycles (Automated Manual Transmission). The patent was filed in 2009 and has received the grant in May this year -2016.

The TVS first introduced a clutch-less gearshift mechanism with the TVS Jive, which didn’t have a mechanical clutch lever on the handlebar, and riders needed to shift gears through a conventional foot-peg mounted lever. The Jive made TVS the first company to launch a clutch-less motorcycle in India.

The semi AMT mechanism used in the Jive actuated the clutch every time the rider operated the shifter and hence the leg effort required was more compared to an ordinary manual transmission. The new invention aims to eliminate this effort by adding another layer of automation to the same technology.

TVS claims that this technology could be used in motorcycles, scooters & three-wheelers as well. Thus the basic working principle remains identical to that of the manual transmission; there won’t be a drop in fuel efficiency as well.
