| 4 4 - Claims that need to be protected: 1. This invention is useful for any rotating body has its own shaft (For whatever the wheel is, rubber or other materials (2) (3) , or it could be pulleys , gears, or other. And for any kind of vehicles it will has a variable distance between the cir cumference and its shaft for shock absorber purposes) we added springs be tween the circumference and its shaft for flexible fixing. To become flexible, (as shock absorber) . Those springs has many kinds, it could be spiral or sheet or rubber. These wheels are supplied with auto or manual adjustment tools as desired, to control the springs length. It could be used in bicycles, tricycles, motor cycle, baby carages, goods trailer, wheel chairs, space wagon, cars, vehi cles, probably in anywhere we need special wheels or pulleys, or gears. 2. As referred to claim 1 we can use different kinds of springs, to be distributed regularly around the circumference and to be alternating distributed between the two external shaft, to insure stability and fixation. 3. As referred to claim 1 vibration range adaptor to adapt and fix the relative an gle between those two external shafts (5), it consist of three main parts: A - The both adjacent external shafts (5) which embrace the internal shaft. B - the springs tension ruler adaptor (10) to be fixed with the wheel circumference toward the wheel shaft, which has two adapter edges (11 turns The springs ten sion adjustment screw counter clockwise, while 12 turns it clock wise) those sensors could be adjusted closer or farther from the adjustment screw (17) due to user needs. In between shafts, there is C - The angle adjustment and fixing angle screw ( 17) between the two shafts (to fix the springs tension) the screw is fixed with one of external shaft, and its able to rotate around its axis (19) , but the other external shaft is screwed (18) to be compatible with adjustment screw. When the adjustment screw turns right or left, if, 1 - Automatic, when the rulers two edges ( 11, 12) hitting the screw nut (7) . Or 2 - manual turning so the relative angle between the both external shafts will be increased or de creased, so springs will be longer or shorter for each wheel separately to suite the load distribution Fig 5. 4. As referred to claim 1, The disc between the two domes system and its accessories 22 , 23 figs 10, 11, 12 the two opposite domes are fixed on the axis of the frame, and hold between them the frame's disk . Between each two parts there is anti- friction material. 5. As referred to claim 1, Balance cables and pulleys system 28, 29 figs 8, 9A set of cables installed on both ends of the frame in a parallel way. The cables wrap several rolls on pulleys distributed regularly around the axle. 6. As referred to claim 1, The pair long supported wheel system 26 figs 12, 13 to be fixed on the bicycle body close to the bicycle wheel, opposite each other. It could be one or more pairs. Fixing the angle between the wheel and its axis. 7. As referred to claim 1 we can fix metal rope (13) or metal cable (14) between the springs two expanded edges, for fixing the maximum length. 9. As referred to claim 1 we can fix a rubber piece or any other material (15) be tween the springs two expanded edges, for fixing the maximum length. 10. As referred to claim 1 we can add to the springs using one or more of the follow· ing: metal rope, or metal mesh, or metal cable, or rubber piece. |
The spring shock absorber for wheels, gears and pulleys 2 - The technical explanation :
A - The previous technical invention
Nowadays all wheels, pullies and gears, in general have a fixed radi us, that means the distance between the shaft and its circumference is fixed, and the materials in-between could be rods, cables, plastic or metal materials.
B - Detailed explanation of the invention:
Usage area: Could be used in bicycles, tricycles, motor cycles, electric cycles, baby carages, good- trailers, wheel chairs, space wagons, cars, vehicles, and in any appli cation having wheels , pulleys, or gears.
This invention advantages: 1 - Save users vertebral column. 2 - keeping users comfort and joy feelings specially while go up or down pedestrian edges and holes,
3 - Longer lifespan for the wheels and the vehicles. 4 - flexibility and lighter weight. 5 - strength, less cost for a long term.
The main parts:
1. The metal frame (3): it is the tire holder as in the typical bicycle in this frame we fix one edge of the springs. Figs from 1 to 4 .
2. The tire (2): It could be air filled or it could be cast material. Figs from 1 to 4 .
3. The wheel shafts: Consisting of two main parts: 1 - The internal shaft (4) with its two screwed edges (6) to be fixed with the bicycle or the vehicle's body with nuts and it will be the shaft and holder for 2 - The two adjacent external shafts (5). These two external shafts are fixed with disc (8) and has holes (9) for springs to be fixed in or can be connected by any other way. There is an an gle between those two shafts , and it could be adjusted. Fig. 5 A.
4. The (shock absorber) springs: These springs (1) could be spiral or sheet or rubber. Probably to be fixed with one of spring ends (16) to the metal frame. And the other spring end to the disc (8) . springs quantity could start from one and up. Between the springs two expanded edges we can fix one or more of the following: 1- A rubber piece (15) or/ and 2 - metal or other material rope (13) or /and 3 - metal mesh (14) or and 4 - suitable metal or other material cable. It is for fixing the maximum length, in this case it will be as the typical bicycle rods. Fig 6.
5. Vibration range adjustment: It consists of the following parts (5 , 17, 18, 7, 10, 11, 12) and its three main parts are: A - The twin adjustment external shafts (5) which embrace the internal shaft (4). B - the springs tension ruler (10) to be fixed with the wheel circumference, which has two limits (11 turns The springs tension adjustment screw counter clockwise, while 12 turns it clock wise) those limits could be adjusted closer or farther from the adjust screw (17) as per user needs. Between the two external shafts there is C - The springs tension adjustment screw (17) fixed with one of external shaft, its able to rotate around its axis (19) , but the other external shaft is screwed (18) to be compatible with adjustment screw. When the adjustment screw turns left or right, when 1 - the rulers two edges ( 11, 12) hitting the screw nut (7) . Or 2 - manual turning so the relative angle between the both external shafts will be increased or decreased, so springs will be longer or shorter. When springs get more stressed that means less vibrations, and less stress means more vibrations. Vibration range adjustment could be either 1 - manual or 2 - automatic For each wheel separately to suite the weight distribution . Fig 5 l
6. The wheel and its axis angle keeper and anti-bending system:
a. The disc between the two domes system : they are two opposite domes fixed on the axis of the frame, and hold in between the disk which fixed to the frame. In between each two parts there is anti- friction material
b. Cables and pulleys system: A set of cables installed on both ends of the frame in a parallel way. The cables wrap several rolls on pulleys distributed regularly around the tire axle.
c. The long supported wheel pair system: to be fixed on the bicycle body close to the bicycle wheel, opposite each other. It could be one or more pairs.
Braking system: it consist of a trench installed on the axis of the wheel, on its surface there is a flat friction strip that presses on the trench to reduce the speed of rotation.
