Means Announces Details of Electric Controllable Clutches
BERLIN, Germany, December 5, 2018— At this year’s CTI Symposium 2018 event in Berlin, Germany, Means Technical Business Manager Carl Beiser unveiled two revolutionary new technologies that could completely change the narrative of propulsion system design.
Touted as “The Building Blocks of Propulsion Systems Design”, the first of these new designs is a static, electrically actuated CMD (CMD-e) which provides the unique benefits of latching in state and not requiring a constant power supply. When this technology is employed, hydraulic control is completely eliminated, along with all of the cost and complexity associated with it, and electricity requirements are reduced as power is only consumed during state transition.
The second “Building Block” is the new Dynamic Controllable Clutch (DCC), which packages in dynamic clutch positions where typically dog clutches, synchronizers and wet friction clutch packs would be located. Using electric actuation, the DCC eliminates the need for complex hydraulic systems and creates substantial packaging and system efficiency benefits.
Combining these Electro-Dynamic and Electrically Actuated Controllable Clutch Technologies within a multispeed gearbox, a new level of sophistication can be introduced into the electrification of the automobile. More speeds can be added to the transmission, efficiency is markedly improved, and it is all done without needing more packaging space.
Whether the system is used in a DCT, AMT, BEV, HEV, PHEV or DHT, the Means Static CMD-e and Dynamic Controllable Clutch provide OEMs with proven solutions to many of the fundamental challenges that the electrification revolution will pose, now and in the future.
