Abstract

In exemplary embodiments, a regenerative suspension system replaces or complements a standard shock absorber on a vehicle. A pump attaches via a hose to a central accumulator cylinder that is mounted along the frame rails underneath the vehicle. Pressurized fluid, air, or other material charges the accumulator. The Pressurized fluid, air, or other material is controllably released via a valve in order to perform work.

Claims (11)

1. A system for charging a power supply of a vehicle comprising:

a central battery, and

a plurality of regenerative suspension systems, wherein each regenerative suspension system is manufactured as an accessory for said vehicle and comprises:

a hydraulic fluid piston configured for the pressurization of hydraulic fluid upon the compression of said hydraulic fluid piston,

a hydraulic fluid storage unit functionally situated and configured to receive hydraulic fluid pressurized by, and dispelled adjacent from the top of, said hydraulic fluid piston,

a hydraulic motor, and

a generator,

wherein said hydraulic motor and said generator are co-housed,

wherein said pressurized hydraulic fluid rotates said hydraulic motor,

wherein said hydraulic motor is configured to rotate the shaft of said generator, and

wherein said generator is configured to charge said central battery.
