Project Description:

         Parker hydraulics has an annual competition which challenges engineering students to construct a bicycle powered by a hydraulic drive system rather than a standard chain drive system. Our Project will meet the requirements for the competition.

 

Requirements:

- Fabricate/retrofit a recumbent bicycle to accommodate a hydraulic drive system

- Two-pump system stores hydraulic pressure from first pump in accumulators, releases to second (driving) pump via throttle

- Start-up assist

- Inline accumulator/system pressure gauges

- Pressure relief valves

- Design a regenerative braking system to recapture energy typically lost in braking

-Three-way valve recycles driving-pump activity back to accumulators
