In a race car, the motion of the shift lever is either "push forward" to up-shift or "pull backward" to downshift. If you are in a gear and you want to go to a higher gear e. To go from 3rd to 4th, you push the lever forward again. To go from 4th to 5th, you press it forward again.
It is the same motion every time. To drop back down a gear, say from 5th to 4th, you pull the lever backward. In European mass-produced automobiles, the shift lever moves forward and backward to shift into higher and lower gears, respectively.
In Formula One cars, there are actually two paddles on the sides of the steering wheel, instead of a shift lever. The left paddle up-shifts, while the right paddle downshifts. On a motorcycle, you do the same thing, but instead of moving a lever back and forth with your hand, you move a lever up and down with your foot.
This rotation causes the rods or forks to move according to the grooves in the drum, changing the gears. Because of the drum, you have to shift in sequence. There is no skipping, for example, from first gear to third. You must always go through second gear to get to third gear.
It is the same when downshifting. The advantage of this system is that shifting mistakes are impossible. You always go to the next gear. There are four main reasons for this preference:. The other advantage is that the sequential shift lever takes up less space in the race car cockpit. Nearly all race transmissions use the sequential shift approach. The drum is rotated manually by a lever in the cockpit, or it is rotated by solenoids, pneumatics or hydraulics that are activated electronically.
