Dual clutch Transmission

Highly efficient future mobility

Dual clutches are the talk of the future. Almost every manufacturer is rolling out cars nowadays with a dual dry clutch. New entrants like the hot Proton X70 also uses the intelligent dual dry clutch. The details on the MG HS by SAIC motors also reveal that the vehicle has a dual clutch transmission. Details on the Morris Garages HS can be read by clicking here.

The hype doesn’t stop here, Now we may see common sedans with this technology. The recent launch of the ALSVIN also confirms the availability of same system but with a basic low end design that we may see having failures. The system is designed by AISIN in Japan.

Despite all the new entrants, the system in general was seen in Honda Vezel with a German engineered unit. The design by LUK is one of the best and fast switching clutch design in the world. Even this system had chances of failures due to negligence and poor cooling. Please remember that Honda Vezel is also a Hybrid vehicle with a Gasoline Direct injection technology and is a very powerful crossover with an amazing user experience.

What to Focus on the overall system

The clutch and gear actuation subsystems are developed by breaking down the manufacturing requirements to the subcomponent level. This is always done through a number of surveys that explains what a customer demands. This ranges from mechanical, hydraulic, electric, and electronic design right through to software development.

Benefits of a dual clutch system

Some of the benefits are

  • Modular, requirement-based actuation for wet and dry Dual Clutch Transmission applications
  • Start-stop and sailing operation can be implemented easily
  • Actuation of electric parking lock is possible
  • Low fuel consumption
  • Decreased CO2 emissions
  • Excellent driving comfort and sporty feeling

Wet and Dry double clutches

The new design of wet and dry double clutches enables compatibility with hydraulic power packs and hydrostatic clutch actuators (HCA) through an integrated double CSC (concentric slave cylinder) with non-rotating pistons. Locating the bearing support on the cover prevents support forces on the crankshaft and input shaft. This design is consequently highly resistant to NVH side effects.

Common features of a dual clutch

  • Integrated double CSC (Concentric Slave Cylinders)
  • Design is resistant to NVH side effects (Noise , Vibration and Harshness)
  • No support forces on the crankshaft or transmission input shafts
  • Compatible with power packs and hydrostatic clutch actuators (HCA)

System and Software expertise

The clutch and the transmission is control through an independent software. Because the transmission is adaptive, the learning routines ensure comfortable gearshifts. The system behaves according to the torque pulls and driving behavior of the user.

In addition for the Honda Vezel, Schaeffler offers a complete transmission control software program with a calibration interface. This enables a complete system solution for the workshop such as fixmycar.pk Pakistan.

Fixmycar.pk is the 1st company in the world to decode the cruise unlock on the Japanese Honda variants. The company has full capability to upgrade the Laser Radar software’s, Transmission system software’s and the removal of drive by wire lag which the cars experience due to bad fuel.

Removal of Drive by wire lag due to communication gap between the two ECM,s can easily be diagnosed and removed. We also offer complete training program for the skilled technicians. Please click on the link for any information. Trainings

Hydrostatic Clutch Actuator (HCA)

Most DCD or i-DCD transmission use Hydrostatic actuator with integrated reservoir. It is a standardized component for stand-alone operation with local control unit (LCU) for different applications. The functional advantages of actuators is fast and precise control without additional sensors on the clutch. Also it can help in actuation of different clutches in conventional, hybrid, and electric drive trains.

All of this helps in significant fuel savings. Because HCA offers high efficiency in output and actuation force it can be modified for single or double actuations. Some designs also allow different mounting positions.dual clutch transmission

Active interlock Transmission Actuator

The transmission actuator is an electromechanical system that works independently of clutch actuation. It operates transmissions for AMT / Dual Clutch Transmission applications using two efficient brushless electric motors. The active interlock principle prevents shifting errors without the need for extra sensors.
