Method and Apparatus for Recovering Energy Wheel

Abstract

While the concept of saving automobile's intake of fuel or electricity by converting kinetic energy of an automobile into some form of potential energy, usually either electrical potential or compressed gas potential, in order to later convert that energy back into kinetic energy, has been well recognised over the years, and while the number of regenerative braking techniques and devices have been introduced over the years, with the exception of an electrical engine/generator, these techniques have not been well adapted. That was caused in part by either not a very simple implementation of those devices or by a necessity to completely re-engineer automobile powertrain in order to use those techniques. Present invention introduces a method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified. The new component described here is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. This method of regenerative braking is therefore applicable to all the automobiles, independent of their power source, to newly built automobiles and the automobiles already on the road.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0101] Referring to FIG. 1, the ReWheel (Recovering Energy Wheel) device, of the shape of a cylinder, is added to the traditional automobile's wheel in the place between the traditional Rim and the traditional wheel Hub.

[0102] The ReWheel device operates like a powerful spring placed inside the automobile's wheel, transforming the kinetic energy of a moving automobile into potential energy of compressed gas during the braking process and then transforming back that potential energy of compressed gas into kinetic energy of the automobile during acceleration process.

[0103] The ReWheel device is connected to the Original Hub (40) sitting on the original wheel, by the Original Hub Connector (41). Original Hub Connector (41) extends the original axle by the Extended Wheel Axle (24), going all the way until the Secondary Hub Connector (44).

[0104] The Original Hub Connector (41), is taking the place that would normally be taken by the Original Tire Rim (42). The Original Tire Rim (42) with mounted on it Original Tire (43) is being connected instead to the Secondary Hub Connector (44).

[0105] The body of the device, ReWheel Body (100), is kept stationary by the Stationary Connector (110). The Stationary Connector (110) is, in turn, connected to the part of an automobile's tire suspension system, which is always stationary to the wheel's axle. It can, for example, be connected to the upper ball joint or its equivalent.

[0106] This FIG. 1. shows two accumulators (10) located in the direction of radius coming out of the Extended Wheel Axle (24), having their pressured gas side towards the axle. The ReWheel device can utilize multiple accumulators, each of them being connected to 3-Way-Valves (11) without changing the principle of the device's operation.

[0107] There are number of turbine-like components within this implementation of the ReWheel. One, is the Braking Turbine (31) and the others are the Accelerator Gears (21). This implementation shows two Accelerator Gears (21) standing on the opposite sides of the Central Gear (22), which is being driven by the Accelerator Gears (21). The Central Gear (22) is hard connected to and is rotating on the Extended Wheel Axle (24).

[0108] The Accumulators (10) are pre-charged with Pressured Gas (13), inert gas, like Nitrogen. Originally the other side of the accumulator is not charged. The Pressured Fluid (12) then comes to the accumulator during the braking process and further compressing the Pressured Gas (13). Since the fluid we use in this implementation is oil which is virtually non compressible under pressure, and since it can change its shape and direction based on the pipes it is going through, makes it a perfect conductor of force.

[0109] The 3-Way Valves (11) controlled by any mechanical or electronic device, are, in turn controlling the braking and acceleration of the automobile. They can be in any of the following 3 states: Neutral statewhen all Braking (B) and Accelerating (A) valves are closed; Acceleration state, when braking valves (B) are closed and acceleration valves (A) are open, causing Fluid Stream at Acceleration Time (200), which in turn is causing the Accelerator Gears (21) to rotate faster, in turn rotating the Central Gear (22); and Braking state, when accelerating valves (A) are closed and braking valves (B) are opened, causing Fluid Stream at Braking Time (300), which is causing further compression of the Pressured Gas (13) and further charging the accumulators with potential energy of compressed gas (13), which process is in turn causing the automobile to brake as every force has a counter force.

[0110] The change in the state of the device, causing braking of the the automobile and transforming the energy from kinetic to potential is implemented as follows. At the neutral state of the device (no braking and no acceleration) the Braking Turbine (30), hard connected and positioned on the Extended Wheel Axle (24) is rotating along with the Original Tire (43). The fluid positioned between the Braking Turbine Blades (31) rotates without any pressure applied to it.

[0111] The Fluid inside the ReWheel device for the largest part is always located between the blades of the Braking Turbine (30) and in compressed state (12) within Accumulators (10).

[0112] Braking State.

[0113] When braking of the automobile is desired, the following is done: Port B of the 3-Way-Valve (11) is opened (port A can only be closed at this time); and special blocks are set to move out and back in to block the free rotation of the fluid.

[0114] The movement of the blocks is synchronized with the rotation of the blades not to block the blades and to only block the liquid in between the blades.

[0115] Blocking the liquid is putting pressure on the Braking Turbine Blades (31). Since the Braking Turbine (30) is placed on the same Extended Axle (24) as the Original Tire Rim (42), blocking the liquid works against the rotation of the Original Tire (43). The inertia of the moving car is creating the counter force, which in turn forces the Fluid Stream at Braking Time (300) in the accumulators (10) through the, open at this time, port B of the 3-Way-Valve.

[0116] Acceleration State.

[0117] When acceleration of the car is desired, port A of the 3-Way-Valve (11) is opened (port B can only be closed at this time).

[0118] The Pressured Gas (13) is then able to force the Pressured Liquid (12), creating the Fluid Stream at Acceleration Time (200) to hit the Blades of the Accelerator Gears (21). The Accelerator Gears (21) are in turn rotating the connected to them Central Gear (22), which is standing on the same Extended Axle (24) connected to the Original Rim (42). Used during the acceleration process liquid is then passed back to the Braking Turbine blades (31), via the Fluid Passage back to Braking Turbine (230). At this time the braking turbine is rotating without a load, with no pressure on its blades, and with available space for the liquid in between its blades.

[0119] Neutral State.

[0120] Both ports of the 3-Way-Valves (11) are closed. All the turbines are rotating freely.

Detailed Description of the Alternative Embodiment

[0121] FIG. 2. Shows Alternative Embodiment

[0122] This figure is also showing two volumes within high pressure cylinders (accumulators). One side of each cylinder is filled with liquid and the other side with gas.

[0123] Here, as well, the accumulators are used within the construction being an addition to the automobile wheel's rim and positioned on the extended automobile wheel's axle.

[0124] Here, as well, the gas compressed during the deceleration of the automobile serves as the storage of energy.

[0125] Here, as well, the liquid is being the conduit of force between the pressure on the blades within the rotating turbines and compressed gas. At times the gas is referred to as air, however the only important qualities of these components are liquid and gas. An inert gas, i.e. nitrogen, is more appropriate in this case.

[0126] The turbines, sitting on the same axle as the wheel's rim, affect the rotation of the rim. On this FIG. 2 we have depicted two turbines, the braking turbine (730) on the left and the accelerating turbine (721) on the right, with the two accumulators (710) in between. Rim (702), locked, by the connection 701, to the accelerating turbine (721) on the right, placed on the gears of the extended wheel's axle (724), i.e. both are always rotating with the same speed.

[0127] Acceleration:

[0128] The compressed gas which is pressing on the liquid, which in turn is pressing on the specially angled blades of the acceleration turbine (721), is causing the acceleration. The used for acceleration liquid is then allowed to come in between the blades of the braking turbine (730) on the left via the passage between the accelerating turbine and braking turbine (7230).

[0129] At this time the braking turbine (730) and the liquid between its blades are freely rotating in the same direction as the acceleration turbine (721). This rotation is ensured by the liquid coming from the accelerating turbine (721) and the angle of the blades of the braking turbine (730).

[0130] Braking:

[0131] As seen on the FIG. 2, when the braking turbine axle moves to the left to perform braking the reverse rotation direction mechanism, (the cone or other gear type (700) and the reverwsee rotation direction disk (741)), is used to connect the freely rotating braking turbine (730) with the sitting on the extended wheel's axle disk (742).

[0132] That makes the braking turbine (730) to start rotating in the direction opposite to the rotation of the wheel (743). The angle of the turbine's blades affect the liquid to be pushed in the direction opposite to where it came from, i.e. in the direction shown in (7230) towards the accelerating turbine (721), which is sitting on, and is being locked to the extended wheel axle (724). The liquid is now pressing against the rotation of the accelerating turbine (721) and therefore against the rotation of the wheel (743), which in turn is causing the automobile to brake, while compressing the air, as shown by the (7300). Additionally, at the time when the breaking turbine axle moves to the left to perform braking, air pumping pistons (709) get connected to the power-train axle.
