Gear system type

Some of the information that may be confusing or a little inaccurate from automotive engineering (such as calling CVT Semi-automatic or putting a Dual-clutch image in CVT), but to answer the problem, I'll explain it by the type of real gear system that is used today, based on the name in the picture.

1. Manual Transmission

A system in which the driver must step on the clutch and shift gears on their own through the gear lever.

• Advantages:

• Durability: Mechanism is not complicated, easy to maintain and the cheapest repair cost

• Control: Feel one with the car, command power as you like (fits the racing line or up the hill down the creek)

• Performance: Power loss in the system is less than some types of automatic transmissions.

• Disadvantages:

• Difficulty: Difficult to drive in the city, parking is jammed, because the clutch must be stepped often.

• Skills: Requires proficiency. If the gear change does not correlate with speed, it can cause engine outage or gear damage.

2. CVT Transmission (Continuously Variable Transmission)

In the painting, Semi-automatic, but CVT is actually a gear that uses belts and pulleys to change the continuous ratio.

• Advantages:

• Softness: There is no twitching from the gear shift because the ratio is flowing.

• Fuel saving: Can maintain optimal engine cycle torque at any time

• Lightweight: Structurally more compact than a cog automatic transmission

• Disadvantages:

• Feelings: The accelerated rate may seem "chin pills" unexpectedly for people who like to drive fast.

• Durability: The belt has an easier chance to swipe or lack than a steel gear if heavily used or frequently overloaded.

3.Dual Clutch Transmission (Dual-Clutch Transmission - DCT)

(Note: In the lower left image, it is written CVT, but the illustration is a dual clutch gear with Gear Set and Dual-clutch).

• Advantages:

• Very sensitive gear change: Use two clutches (one to control odd gears, the other to control even numbers), causing the next gear to be held. Change gears in a split second.

• Satisfying Fun: Give Sporty Mood Sharp and Fast Gear Shift

• Disadvantages:

• Complexity: There are a lot of electronic and mechanical components, making body and repair expensive.

• Driving at Low Speed: In some cars there may be spasms or clumsy when crawling along a car.

4. Automated Manual Transmission (AMT)

It's a manual gear with an Actuator to help us step on the clutch and shift gears.

• Advantages:

• Low cost: Production cost is cheaper than genuine automatic transmission, making car price cheaper

• Fuel Saver: Basically a manual transmission, so the power loss is small.

• Disadvantages:

• Shift stroke: usually has a "prick head" or stumble during the robot chopping gear, not as soft as CVT or DCT.

• Response: Sometimes the mechanical brain may change gears slowly or fail to satisfy the driver.
