Abstract

The device which can be fitted to a vehicle eg bicycle or wheelchair or other machine, where a moving mass is brought to rest or slowed down by storing its kinetic energy within an elastic element [2]. The energy can be released by the movement of a ratchet device or other temporary locking device, thus allowing the elastic element [2] to return to its previous shape while releasing its stored energy. The displacement of the elastic element during energy release is transferred through a system of gears [A] and [B] and roller clutch in such a way that the moving mass is accelerated in the same direction of travel as when it was slowed down. <IMAGE>

Description

DESCRIPTION This invention is a mechanism which stores energy used in braking a vehicle.It then holds the energy within a spring until it is required for release , to assist in the propulsion of the vehicle. The term used for this procedure is regenerative braking.
Conventional brakes will not be used during the operation of this mechanism , but may also be mounted to the vehicle as a secondary back up system , and a means of braking the vehicle when the spring is fully compressed to it's safe working limit.
It is thought that this system would be most effective when applied to man-powered vehicles..eg.
bicycles, invalid wheelchairs , etc. Fig 1 shows the operating principle of such a mechanism.
BRAKING (Fiq 1) When such a vehicle is moving with some velocity v , and braking must occur , then the rotating wheel [1] must be connected to the coil spring [2] .Fig 1 shows how this is achieved. A clutch/coupling [3) drives a sprocket [6] and a chain , which in turn drives a sprocket [5] , a gear [A] and a gear [B] which is connected to the coil spring [2].
In this way the Kinetic energy of the vehicle and driver are offered to the spring as a torque. This torque is used in working or compressing the spring , and hence a braking effect' ''is produced due to the springs resistance to movement.
The energy stored during braking is held in the spring by means of a ratchet device [4]. The mechanism can be kept in this state until the stored energy is required to assist the propulsion of the vehicle.
PROPULSION (Fig 2) The stored energy may be returned to the road wheel [1] by releasing the ratchet device [4] , and de-meshing gears [A] and [B] , and meshing gears (A) and [C) (Fig 2).This allows the spring to expand (or unwind) in the opposite sense to that during braking but turning gear [A] in the same sense to that during braking via idler gear C.
Gear [A] is connected to the chain sprocket [5] which drives another sprocket [6] mounted on the clutch/coupling device [3]. This sprocket drives the road wheel [1) by means of a ratchet device [7] built within the clutch/coupling [3].

Claims (1)

1) A regenerative braking device comprising of an elastically deformable element connected in such a way as to store the kinetic energy of a moving body causing it to reduce in speed. The release of the said energy from the elastic element is used to assist in accelerating the said body from its previously reduced speed.
2) A regenerative braking device as claimed in claim 1 wherein roller clutches are used in such an arrangement as to reverse the sense of the rotational movement caused by the elastic element releasing its stored energy.
3) A regenerative braking device as claimed in claim 2 wherein the energy entering the elastic element can be stored for an indefinate period of time by means of the frictional locking of a metal roller between two metal surfaces similar to a ratchet mechanism.
4) A regenerative braking device wherein the said stored energy can be released as described in claim 2 by the movement of a said metal roller as described in claim 3.
CLAIMS 5) A regenerative braking device as claimed in claim 1 wherein kinetic energy is transferred from the moving body into the braking device by means of a clutch mechanism.
This clutch mechanism may override at a predetermined torque to create a constant braking effect when the elastic member is fully deflected.
6) A regenerative braking device substantially as described herein with reference to Figures 1 and 2 of the accompanying drawings.
