How A Motor Works

There is A Transmission defined as a mechanical structure which transmits power from the Engine. The transmissions might have no ratio and one. This article will reveal the workings of the 6 speed bike transmission, but 5 speeds and the 4 work the same manner. When it is engaged, the Clutch applies to the transmission’s Input Shaft power and the Engine is running. The input\/drive shaft turns anytime and all a time that the clutch is engaged. There is a drive\/pinion gear for each ratio. The input rotating gears mesh with their corresponding drive gears that ride on the Output\/Driven Shaft.

Motorcycles use Constant Mesh type transmissions. This name comes from the equipment pairs are meshed. These gear Sets\/Pairs provide the gearing ratio changes that we use to go from standstill speed to top speed, and in our situation a high transmission ratio of 3.1: 1 for our first gear and 0.8: 1 for our sixth gear. The 3.1: 1 Ratio of first implies the Input Shaft has to make 3.1 revolutions for each 1 revolution of the Output Shaft. The 0.8: 1 Ratio of sixth implies that just 8 turns of the Input Shaft contributes to 1 complete revolution of the Output Shaft.

Some of the gears in our transmission are keyed\/splined to the shafts they ride on and some spin freely. No two equipment Pairs can be locked at the same time. Doing so would have catastrophic results since they’d each try to turn the output rotating at various speeds. The job of bike gear altering falls on this Shift Forks and Shift Drum to ensure which complete control and positioning of this splined gears be precise and correctly timed. The Shift Drum has pig stations cast or machined on the surface. These stations supply and manage the directional control for every one of the Shift Forks.

As the Drum rotates, the stations hold or move this Forks right or left to engage along with disengage this various splined gear sets. The Shift Drum moves in a rotational manner, but never a complete 360 degrees. The Drum is limited and rotation stops at its lowest and its highest positions. Neutral is obtained when all gear pairs are unlocked and the Output\/Driven shaft is not powered. Most Neutrals are now designed between first and 2nd. The Shift Drum has this mechanical Stop for a reason.

For that reason, Shift Drums have built-in rotation limits built-in. While Neutral might be designed to fall between each gear change, that function will be undesirable and a real nuisance.
