From: Formulating a multi-layered framework for automobile architecture
Electric 2-wheeler design options | |||
|---|---|---|---|
Option | Option name | Detail | Illustration |
A: Battery: Storage, supply and renewal of energy | |||
a | Battery | Liquid state Lithium Ion battery. Remaining options like fuel cell and solid state battery are not in a stage where they can be adopted for two wheelers. Moreover various options within liquid state Li-ion battery are same in architecture and do not affect the interfaces |
|
B: Drive: Conversion of of stored energy into rotational energy | |||
b1 | Rigidly fixed motor | Brushless DC motor |
|
b2 | In-wheel hub motor | Internal/external/axial rotation |
|
C: Transmission: Regulating desired torque and speed relationship and coupling and decoupling with Output | |||
c1 | Rigid Geared transmission | Gear pairs coupled with clutch |
|
c2 | In- wheel geared transmission | Axial or parallel coupling with in-wheel motor | |
c3 | Variometric transmission | Centrifugal pullys with toothed belts and centrifugal clutch |
|
c4 | Controller | Torque regulation through electrical signals and decoupling after braking |
|
D: Rear wheel: Traction | |||
d1 | Rear wheel | Cast or spoke | |
E: Rear brake | |||
e1 | Rear brake | Disc or drum, hydraulic or mechanical | |
F: Frame: Holding all systems | |||
f1 | Frame | Down tube, monocoque, diamond or any other conventional frame | |
