1st gear

The most common torque and often the most important is the nominal torque. This is the torque that can transmit a gearbox for a long time without any interruption. This torque is also called RMS torque (Root Mean Square) and can be calculated using the formula listed in our catalogues.

This is critical – we’re producing more torque at 6500rpm in second gear (647Nm) than we are at the engine’s max torque at 3500rpm in third gear (598Nm).

A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.

A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.

If a gear gives you more force, it must give you less speed at the same time. If it gives you more speed, it has to give you less force. That’s why, when you’re going up hill in a low gear, you have to pedal much faster to go the same distance.

If you have manual transmission, you will likely have noticed that driving in too high a gear for your speed and RPM range causes the car to shake and move slowly, commonly known as “lugging.” Lugging creates an unnecessary strain on the engine and can damage your cylinder heads, leading to expensive repairs later on.

It is not OK to drive a car always in 2nd gear at 40 KM/Hour. First, it impacts the fuel efficiency badly. Second, the deceleration in second gear, when you take your foot off the accelerator is so rapid, you may lose control. May be it is okay when you are driving uphill or downhill at such speed in 2nd gear.

Engineering Explained tackled the common practice in its latest episode and the short answer is yes, it’s perfectly OK to skip gears when upshifting or downshifting. When skipping a gear with a manual transmission, it should be noted the revs will take slightly longer to drop from the high revs to the lower revs.

If you want to use engine braking to slow down, you can rev-match your downshifts to lower gears (without using the brakes). Heel/toe is actually a gas and brake action. You still need to your right foot to step on the clutch so, heel/toe makes no difference.

A: The purpose of rev-matching is to match the engine speed to the transmission speed. The purpose of double clutching is to match the engine’s input shaft to the gear and transmission output shaft you are shifting into. If the speeds aren’t matching, it will not be able to shift into gear.

While double clutching is not necessary in a vehicle that has a synchronized manual transmission, the technique can be advantageous for smoothly upshifting in order to accelerate, and when done correctly it prevents wear on the “synchros” which normally equalize transmission input and output speeds to allow …

Shifting without the clutch, of course, can cause damage to your vehicle’s transmission, especially if not executed properly. However, in order to learn how to shift properly without using the clutch, you will probably grind the gears at least a few times.
