| ABSTRACT |
|
This paper deals with a novel clutch mechanism for transmission applications, which aims at easy application
of the transmission as the micro-electric vehicle models expand in variety. The new mechanism actuated by the torque and
rotational inertia of the traction motor instead of the conventional hydraulic or electronic actuator and features a simple
structure compared to the conventional mechanism. The operating principle, structure and mathematical modeling of the new
clutch mechanism are presented, and verification of mathematical modeling was done through comparison of experimrntal and
analytical results. To investigate the automotive suitability of the new clutch mechanism, the shift characteristics are analyzed
by longitudinal directional vehicle dynamic model applying new clutch mechanism. As a result of the analysis, it was
confirmed that the shift shock absorbing ability and required time for shifting are applicable to the vehicle transmission. |
