F16D2500/506 - CPC Classification

Classification description:

External control of clutches by electric or electronic means; Problem to be solved by the control system Relating the transmission

Sub-classes:

F16D2500/50607 » Facilitating engagement of a dog clutches, e.g. preventing of gear butting 22
F16D2500/50615 » Facilitating disengagement of a dog clutch, e.g. by appying a pretension on the disengaging elements 11
F16D2500/50623 » Preventing transmission load change 6
F16D2500/5063 » Shaft dither, i.e. applying a pulsating torque to a (transmission) shaft to create a buzz or dither, e.g. to prevent tooth butting or gear locking 3
F16D2500/50638 » Shaft speed synchronising e.g. using engine, clutch outside transmission 8
F16D2500/50646 » Control of the main clutch to prevent or release a tooth-to-tooth condition in the transmission 2
F16D2500/50653 » Gearing shifting without the interruption of drive 13
F16D2500/50661 » Limit transmission input torque 3
F16D2500/50669 » Neutral control, i.e. preventing creep or drag torque being transmitted in a transmission with a torque converter when the vehicle is stationary 5
F16D2500/50676 » Optimising drive-train operating point, e.g. selecting gear ratio giving maximum fuel economy, best performance 7
F16D2500/50684 » Torque resume after shifting 47
F16D2500/50692 » Simulate the characteristics of a torque converter 2
