Abstract:
Carbon emission, which is the most important effect of global
warming, is a serious problem. Various studies have been carried out for
vehicles to emit CO2 per unit km. However, the way to reduce
emissions in the near future is through hybrid vehicles.
Parallel hybrid, serial hybrid, and power-sharing hybrid are the three forms of power transmission in
hybrid vehicles. In some hybrid power transmission systems, the internal
combustion engine can contribute directly to the movement of the vehicle. In some hybrid power transmission systems, the internal combustion engine does not
contribute directly to the movement of the vehicle. The most important purpose
is to transmit the power obtained from the internal combustion engine and
electric motor to the gearbox and wheels with no problems.
In this thesis, an experimental process has enabled
the internal combustion engine and electric motor to transmit power to the
gearbox input independently of each other. In order for the internal
combustion engine to transmit power to the gearbox input instead of a dry type
clutch, an electromagnetic clutch that allows the amount of torque transmission
and clutch status to be controlled by electronic signals is used. The power
transmission of the electric motor to the gearbox input is realized by a
chain-gear mechanism. A one-way clutch is used to transmit power to the gearbox
input of the electric motor independently of the internal combustion engine.
With this clutch, the electric motor is prevented from rotating the internal combustion
engine and the power transmission of the internal combustion engine and the
electric motor is provided independently. In this study, the system validated the process experimentally.
