Abstract

The braking system comprises a hydraulic pump/motor B clutched to a rotating part H of a vehicle to drive or be driven thereby. In the braking mode the pump/motor is driven and fluid is supplied to an accumulator A for storage through three way switching valve D and a check valve E. Two way valve F between the accumulator and a pump/motor intake is closed. In the driving mode the valve F is opened to supply actuator fluid to the pump/motor and the three way valve D is switched to supply its outlet to tank C. In a neutral mode the pump/motor is declutched, valve F closed and valve D set to neutral. Electrical switched to operate the system may be on vehicle operating pedals or a gearbox.

Description

241 0476 Hydraulic energy regenerator The purpose of the regenerator here
described is to assist in the slowing of a moving vehicle, as a by product of this braking function hydraulic oil is stored under pressure thus giving a reservoir of FREE energy, this energy can then be put back through the same system to assist in the acceleration of the said vehicle as and when required.
Electrically operated multi-position valves control the system. These valves in turn have their positions dictated by a set of electrical switches.
A Accumulator. To store hydraulic pressure.
B. Hydraulic motor/pump. To produce hydraulic pressure/ act as hydraulic motor C. Hydraulic reservoir D. Three way valve. To control pressure flow E. None return valve F. wo way valve (on/ofI) G. Pressure relief valve H. Clutched drive. A rotating part of the vehicle only connected to system when required.
I. Pressure sensor. To turn system off when accumulator fully charged/discharged.
Fig I shows the system at rest.
Valves F and E holding any pressure stored.
Valve D set neutral.
Motor/pump B not connected to clutched drive H. Fig 2 shows the system in braking or charging mode Valve F still closed Valve D set to allow flow to the accumulator Motor/pump connected to clutch drive H. The motor/pump H is being driven and is pumping hydraulic fluid under pressure through the three-way valve to be stored in the accumulator as valve F is closed. When the accumulator is full the pressure sensor I will turn the system to REST.
Fig 3 shows the system in Drive or discharge mode.
Valve F is now open and allowing any stored hydraulic pressure to the motor/pump.
The motor/pump B is now driving the clutch drive H Three way valve D is allowing fluid to flow freely back to the hydraulic tank C. The pressure sensor I will turn system to rest when accumulator is empty.
The system should fail safe to Fig 1, unless safety items ie power steering are run from the accumulator side of the system, then it should fail to Fig 2 by -with valve F open.
In normal operation valve F should only open when the accelerator is being pressed and the vehicle is in gear. No other controls should be in operation.
Valve D should go to position Fig 2 when brake pedal only is being pressed and position Fig 3 when accelerator is being pressed.
The clutched drive should be disengaged when ever possible and only engage when charging or discharging. So when the vehicle is braking and the accumulator is not fully charged it should engage until full then disengage when the pressure sensor I says the accumulator Is full. In reverse when accelerating the clutched drive should only be engaged until the pressure in the accumulator is spent.
All switches to be set so as to allow the system to work.
These electrical controls can be automated through a series of micro switches on the pedals and in the vehicles gearbox.

Claims (1)

  1. HYDRAULIC ENERGY REGENERATOR
    A hydraulic energy regenerator can be fitted to any vehicle with rotating wheels in contact with the ground, it may be constructed from individual components or manufactured as one device, constructed from any suitable material, the regenerator can be fitted to any rotating device.
    The regenerator will allow for the reuse of the energy used to slow a vehicle/rotating device.
    The device operates without any need for input from the operator.
    Composed of a pump/motor, accurnu]ator, flow valves, electrically controlled flow valve and a tank the system is a self-contained system.
