This document provides an overview of a parallel hybrid drivetrain project. It describes the key components of the powertrain including an electric motor and internal combustion engine. It also outlines the transmission layout, including the use of clutches and a hydraulic system for gear shifting. Details are provided on the gearbox housing design process and electronics. The document concludes by describing the test rig that was built to evaluate the performance of the hybrid system and names the various team members and organizations that contributed to the work.

Heart
Engine
Motor
 Input conditions fix from motor
And engine torque v/s rpm
characteristics
 Output conditions fix from
minimum road-load power
equation for a vehicle
 To find -: Gear ratio between input and output using these fix conditions

5. Transmission layout

6. Gearbox - Clutches
 Need for clutch-: Disengage
power source from the
gearbox, shift between gear
ratio
 Problem-: EM clutches too
big and heavy for a vehicle
 Solution-: Friction clutches
 Problem-: Actuation force too
high
 Solution-: Hydraulics

7. Clutch
 Clutch chosen based on
maximum torque achievable
 Splendor, Xtreme have
comparable power, torque with B&S
 Problem-: Too costly
 Solution-: Atul Piaggio clutch

8. Hydraulic System
 Pump
 Cylinder
 Tank
 Oil Filter
 Manifold block
 Connectors
 Hoses
 Motor
 Transmission drive
 Pressure gauge
 Relief valve
 Oil indicator
 Solenoid valve

9. Hydraulic- calculation methodology
Fix pressure
