TREMEC TR-9070 DCT

7-Speed Dual Clutch Transmission

TREMEC dual-clutch technology has transformed automated manual

transmissions with the new TR-9070 DCT. The innovative transmission

provides extreme performance with 900 Nm torque capacity and lightning

fast shift transitions as fast as 80 milliseconds.

Depending on the requirements of the situation and mode, the fun-to-drive

7-speed dual-clutch transmission thinks, learns and performs - whether it

be normal driving, sporty driving, drag racing or track racing.

Layout

The main objective of the DCT layout is to make the transmission as

light and compact as possible. To this aim, all hydraulics, sensors and

clutches are fully integrated into the gearbox. A successful light-weighting

strategy incorporates die cast aluminum housings, a compact gear-train

arrangement, hollow shafts, a plastic sump pan, and more.

Control packages

The DCT is controlled with a high-performance, 32-bit transmission control

unit. The TCU controls all functions of the gearbox, including the hydraulic

system, the two clutches, the eight gears (first through seventh and reverse)

and the park lock. All systems and subsystems - including hardware such

as low-leak solenoids and electro-hydraulic actuation systems, to control

systems and software - were internally developed for maximum performance.

Software solution

In order to create the desired feel during launch and shifting, TREMEC

engineers developed advanced algorithms to calculate torque targets, in real

time. An underlying torque chain converts the targets into an electrical target

for the control valves, making torque control fast and repeatable.

Clutch design

The clutch design marries the benefits of wet and dry clutch technologies

into a hybrid design. A highly efficient wet clutch system with optimized

friction materials have the ability to cool the clutches with lubrication

individually and only when needed. The end result is a controllable

thermal load and much lower drag.

Clutch architecture

Clutch cooling

Rear-wheel drive, seven-speed dual clutch transmission

Parallel wet dual clutch - normally open with separator springs to eliminate drag

With engine torque control, thermal events are predicted and controllable.

Cooling is proactive (not reactive) for long life and high efficiency. Parallel

architecture allows ability to cool clutches individually only as needed, which

increases efficiency.
