Abstract

The following report discusses the implementation of a hydraulic launch assist system to function as a method of regenerative braking in a hybrid motorcycle. The design will be implemented on a hybrid gasoline-electric motorcycle constructed by past groups during Phases I through III of the Capstone Hybrid Motorcycle Project. Multiple design options were considered including hydraulic and electric systems. The final design consists of a customized hub pump/motor based on a variable axial piston pump, a diaphragm-type accumulator, and a 1.5 gallon reservoir integrated into the existing fuel tank. This system applies torque to the front wheel to assist the motorcycle during acceleration. The system operates at an input RPM ranging from 0-875 and within a temperature range of 32- 120F. The operating efficiency of the system is between 79.2% and can recover 169 kJ of energy along the EPA Urban drive cycle. The overall estimated prototype cost for this system is $4,475.
