Team Hybrid Sub-Systems


The overall Team Hybrid solution has been broken down into 3 main sub-systems:

     1) the Hydraulic Drive System
     2) the Hydraulic Driven System
     3) the Control System

The Hydraulic Drive System consists of any mechanical motion producing component that drives the hydraulic system.
This includes, but is not limited to: 

     1) the ICE operating as:
          - the FB-4001A generator drive system
          - a parallel drive motor running a hydraulic pump
     2) the FB-4001A electric motors operating as:
          - the ICE driven generator to charge the batteries/ultra-capacitors (including "fan clutch" system)
          - a parallel drive motor running a hydraulic pump
     3) the battery/ultra-capacitor bank operating as
          - an energy storage device
     4) any necessary mounting brackets etc.

The Hydraulic Driven System consists of any mechanical motion producing component that relies on hydraulic pressure to function as needed.
This has 2 parts: 1) regular drive system and 2) regenerative braking system.
This includes, but is not limited to:

     1) the hydraulic pumps acting to:
          - create hydraulic pressure in the system depending on Hydraulic Drive System input
     2) the high pressure accumulator acting to:
          - store pressure in the system to power the hydraulic motors
          - store energy during regenerative braking
     3) the low pressure accumulator acting to:
          - supply the hydraulic pumps with fluid to send to the high pressure accumulator during driving
          - supply the hydraulic motors with fluid to pump into the high pressure accumulator during
            regenerative braking
     4) the hydraulic motors acting to:
          - supply rotary motion to the wheels during driving
          - pump fluid into the high pressure accumulator during regenerative braking
     5) all hydraulic lines and fittings

The Control System consists of any electrical/electromechanical component that is essential to the useful operation of the hybrid vehicle (were it built).
This includes, but is not limited to:

     1) the FB-4001A motor control units acting to:
          - control the RPM, output torque, efficiency, etc. of the FB-4001A motors
     2) the battery/ultra-capacitor controller acting to:
          - control the rate at which these units are charged/discharged
          - monitor these units to determine when the alternator mush be engaged
     3) the check valves and the 4 port, 3 way valve acting to:
          - control the flow to the Hydraulic Driven System components
     4) any necessary code to run the micro-chips etc.
