Electronic clutch controlling device for motor vehicle, has hydraulic circuit with pressure sensor that is connected to drive controller of electric motor, and fluid accumulator controlling progressiveness of pressure increase in circuit

摘要

#CMT# #/CMT# The device has a hydraulic circuit (12) with a pressure generator piston (13) that is displaceable by a control unit (14) e.g. screw or nut system, activated by an electric motor (15), and a slave piston (11) for controlling an electronic clutch (1). The circuit has a pressure sensor (20) connected to a drive controller (16) of the motor based on information provided by the sensor and based on a predetermined clutch driving law. The circuit has a fluid accumulator (25) e.g. spring-loaded piston, for controlling progressiveness of pressure increase in the circuit by the generator piston. #CMT#USE : #/CMT# Used in a motor vehicle for controlling an electronic clutch (claimed) that is utilized in a manually driven gear box or robotized gear box. #CMT#ADVANTAGE : #/CMT# The device permits to improve precision and control of transmissible torque of the clutch. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an electronic clutch controlling device. 1 : Electronic clutch 11 : Slave piston 12 : Hydraulic circuit 13 : Pressure generator piston 14 : Control unit 15 : Electric motor 16 : Drive controller 20 : Pressure sensor 25 : Fluid accumulator.
