How do selector forks work

The spring load forces the balls into their respective grooves when they align Fig. Each of the two forward-gear selector rods has three grooves and the reverse selector rod has two grooves. When the selector rods and their forks are shifted one way or the other, these grooves eventually align with the spring loaded balls or plungers when a gear position is reached. On the forward-gear selector rods the central groove corresponds to the neutral position and the grooves on either side corresponds to engaged position for first or second or third or fourth gear.

The reverse selector has only a neutral and a reverse position. Rod-and-fork gear-selector arrangement. Three-rod gear-selector mechanism with plunger-and-pin interlocking device. Jonathan Grunig.

Every part explained There's ridiculous detail on every part. Clearly and easily explained. All modeled in 3D We've created the most detailed 3D model ever produced so we can show you everything working. Start watching. The rail end is a sheet metal part, inserted within the fork during die casting process itself, thus integrating two parts and making the design simple.

Fork 5 th , in this design, is fixed to the rail by a pin. The actuating rail end and reverse gear actuating finger are also pinned to the rail. Care has been taken in the design to ensure that Reverse gear doesn't get actuated during 5 th gear engagement, as actuating members of both the gears are fixed to the rail and move together.

Detailed CAE simulations have been performed to ensure the stiffness of the aluminium forks and strength of the entire system. Chamfers on the rail ends of forks have been designed in correlation with the chamfers of the H-Gate on Shift tower to ensure a smooth diagonal shifting between gears.
