With the growing traffic density and increasing comfort requirements, the automation of the drive train will gain importance in vehicles. The automatic clutch actuation relieves the drivers especially in urban driving and stop-and-go traffic conditions. In this paper, an electro-mechanical actuator for clutch-by-wire (CBW) system is implemented as the first stage for the development of automated manual transmissions. The prototype of CBW actuator is designed systematically, which is composed of the electric motor, worm & worm wheel and crank mechanism. And the test rig is developed to perform the basic function test for the automatic clutch actuation. The developed prototype is validated by the experimental results on the test rig.

With the growing traffic density and increasing comfort requirements, the automation of the drive train will gain importance in vehicles. The automatic clutch actuation relieves the drivers especially in urban driving and stop-and-go traffic conditions. This paper describes the dynamic modeling of a clutch actuator and clutch spring. The dynamic model of the clutch system is developed using MATLAB/Simulink, and evaluated by experimental data using a test rig. This performance simulator is useful to develop the clutch-by-wire (CBW) system for an automated manual transmission (AMT). The electro-mechanical type CBW system is also implemented as an automatic clutch for AMT. The prototype of CBW system is designed and implemented systematically, which is composed of an electric motor, worm gear and slider-crank mechanism. The test rig is developed to perform the basic function test of the automatic clutch, and the developed prototype is validated by the experimental data on the test rig.

With the growing traffic density and increasing comfort requirements, the automation of the drive train has gained importance in vehicles. The automatic clutch actuation relieves a driver especially in urban and stop-and-go traffic environments. In this paper, an electro-mechanical actuator for clutch-by-wire (CBW) system is implemented as the first stage for the development of automated manual transmissions. The prototype of the automatic clutch actuator is designed systematically, which is composed of the electric motor, worm and worm wheel, and crank mechanism. A test rig is developed to perform the basic function test for the automatic clutch actuation. The developed prototype is validated by the experimental results performed on the test rig.
