Gearbox Types

Gearbox systems are commonly divided into 4 essential categories:

1.Manual Transmission System (MT)

In this device, the driver disconnects the transmission course through pressing the clutch. Manually transferring the equipment, the driver then restores the energy path through letting off the clutch pedal.

2.Automatic Transmission System (AT)

Such structures use hydraulic couplings (torque converters) in place of a clutch. The automated transmission device additionally makes use of solar equipment units in place of easy or spiral gears to permit computerized equipment-switching. An automated transmission device is heavier and greater complex, as a consequence much less efficient than a manual gearbox.

3.Dual-Clutch Power Transmission (DCT) or Semi-Automatic Transmission Systems

Such systems take gain of each guide and automated structures’ merits. However, they may be quite high-priced and have a too complicated design, so they may be in the main utilized in sports vehicles. Dual-clutch energy transmission (DCT) or semi-automated transmission structures use driver-operated electric sensors and switchings to switch gears.

These vehicles have DCT gearboxes with customizable remapping: the DKG gearbox in BMW, Audi S-Tronic, VAG in VAG models; PDK in Porsche; the PowerShift device in Ford; and 7G-DCT in Mercedes.

Let’s call a few automatic gearboxes with remapping customizability: the VAG Tiptronic, G-Tronic set on Mercedes-Benz; the 8-pace ZF gearbox or ZF 8HP used withinside the BMW X Series; the ZF 9HP in BMW, Chrysler, Dodge, Alfa Romeo, Audi, Jaguar, and Land Rover.

4.Continuous Variable Transmission (CVT)

Continuous variable transmission excludes equipment conversation and is a great opportunity to discrete gears. In fact, CVT structures use endless various speed ratios to gain most useful engine overall performance in unique operating conditions. Today, maximum American and Japanese cars, inclusive of Ford, Nissan, Fiat, Mitsubishi, Chrysler, Lexus, Honda, and Subaru. These producers aim to enhance those structures’ efficiency. There are many varieties of CVT structures, together with pulley-primarily based systems, toroidal, non-stop hydrostatic, variomatic (belt), and BorgWarner.

Multitronic, E-CVT, and CVT Xtronic are common forms of CVT gearboxes with gearbox remapping capability.

What is TUNING? What is the purpose of Tuning?

Most motors with automated gearboxes are equipped with a TCU or Transmission Control Unit. In those motors, TCU has plenty of tasks, which include equipment transferring and torque limitation. TCU is attached to EMS to make sure overall higher performance.

Just as we are able to tune ECU and practice our favored modifications, TCU is likewise tunable, a procedure known as Gearbox Tuning. Gearbox tuning brings many wonderful changes, which include better acceleration and power. In the subsequent lines, we in addition address those changes.

How to do Gearbox Tuning/TCU Remapping?

Gearbox tuning is a software program method completed thru the OBD port, similar to ECU remapping. One of the advantages of the software program technique is that during a few automobiles, separate processors manipulate the gearbox’s performance, and the tunning is definitely implemented to those processors the usage of the software program technique.

Besides, in a few automobiles with changed gearbox, tuning is favored since the ECU needs the precise engine speed and tools ratio to locate the tools position. Usually, gear moving disrupts the tools ratio, and this is why tunning is crucial for solving this problem. Gearbox tuning allows cast off the incompatibility troubles among the brand new gearbox and the ECU and improves the gearbox and vehicle’s performance.

Advantages of Gearbox Tuning:

The advantageous modifications as a result of gearbox tuning are very tangible:

• Increase in tools shifting speed (rate)
• Removing the inherent digital delays of gearboxes
• Ability to growth or get rid of cut-offs
• Improvement in shift points in D for upshift and downshift
• Torque limit Removal
• Better reverse tools shifting in automated gearboxes (that is a function of throttle reaction)
• Improvement in automobile acceleration
• more satisfaction driving sense
• Decrease gasoline efficiency
• Better vehicle release control
• Modification and development of tools shifting patterns
• Tunned automobiles have a better clutch clamping force
• Full Manual Mode
• Kick down DeleteFree Shift in Manual Mode

The TCU is synched with the ECU, and those gadgets work together compatibly. So, in case you are tuning your engine and remapping your car’s ECU, you higher remap the TCU s nicely due to the fact some gearboxes have torque limits; whilst the engine torque increases, those limits save you torque transmission.

Torque limits are a quite common trouble in DSG gearboxes (Direct Shift Gearbox), that are used on Audi, Seat, Skoda, and VW. Let’s find out how DSG works: a Direct Shift Gearbox automates separate “manual” gearboxes (and clutches) contained inside one housing and working as one unit. DSGs have excellent software program tunning potential, and are electronically managed with the aid of using Temic Controllers, and feature the following generations available:

• DQ200
• DQ250
• DQ380
• DQ500
• DQ511
• DL501

DSG ECU Remap Option:

• Increased RPM Limiter
• Increased Shift speed
• Increased maximum Torque
• Launch Control
• Kick Down delete

 

Disadvantages of Gearbox Tuning:

You can not actually name any precise disadvantage for gearbox tuning. Perhaps the only essential point is that you have to allow professional trustworthy tuners tune your automobiles due to the fact you can not apply the identical strategies and use the identical tools for all gearboxes, including Manual gearboxes, CVT, DCT types (including DSG, DKG, Powershift, 7G-DCT, S-Tronic), G-Tronic.
