Abstract

The name of invention is Multilevel Dormant Electronic Gearbox. The invention relates to all fields that use gearboxes. WIPO classification is: F16C. The invention is gearbox. The problems in existing gearboxes are that they are large, heavy weight with many moving parts and fewer gears. Our invention is a gear box with a small number of parts, which has a smaller size, less weight, easier to manufacture and maintain and they are more gears (for example 18). The application of the invention is to replace any classic gearbox. Engine transmits the movement towards multi bevel gear (fig.1 pos.5). Multi bevel gear transmits the motion to standard wheel-gear (fig.1 pos.6). This wheel gear moves along the rotary axis (fig.1 pos.7) and also spins it. The rotary axis transmitts the motion forward.

Description

Description of the Invention

LName of invention:

Multilevel Dormant Electronic Gearbox (MDEG)

2. Technical Field:

F16C - SHAFTS; FLEXIBLE SHAFTS; MECHANICAL MEANS FOR TRANSMITTING MOVEMENT IN A FLEXIBLE SHEATHING; ELEMENTS OF CRANKSHAFT MECHANISMS; PIVOTS; PIVOTAL CONNECTIONS; ROTARY ENGINEERING ELEMENTS OTHER THAN GEARING, COUPLING, CLUTCH OR BRAKE ELEMENTS;

BEARINGS.

3. Background Art:

The development of gearboxes in the last forty years is moving towards the development and improvement of existing methods of transmission of the movement. The main type gearboxes used today in the automotive industry has reached its last stage of development.

Latest gearboxes are complex to manufacture and maintenance. The maximum number of gears is 9. A further increase the number of gears would have more minuses than pluses.

4. Disclosure of Invention:

The essence of the invention is in the method of transmission of the movement in gearboxes by a new item we called Multi bevel gear. The advantages of the invention are: a smaller size, a smaller number of moving parts, simpler structure, less weight, less power loss. It allows for a greater number of gears (eg 50).

5. Brief Description of Drawings::

Figure 1 :

1 crankshaft - it comes with the engine;

2 release bearing - it may be like the release bearing of the classic clutch;

3 fork lever - it may be like the fork lever of the classic clutch;

4 moving device - there are a variety of such devices;

5 multi bevel gear - It consists of several bevel gears, one inside the other. So far there is no such element;

6 gear-wheel - may be a few independent wheel-gears to increase the number of gears;

7 rotary axis - It transmits the movement forward; 8 gearbox housing - It depends on the engine, on which is mounted;

6. Best Mode for Carrying Out the Invention:

The crankshaft of the engine (Fig. 1 , pos. 1 ) transmits the motion to a "multi bevel gear" (Fig. 1 , pos. 5). The multi bevel gear rotates around its axis. Over the main surface are multiple gears (Fig. 2, pos. 1 ). These gears consist of "teeth" (Fig. 2, Pos. 2). Each gear has a different diameter and ratio. These„teeth" moves the wheel-gear (Fig. 1 , pos. 6 & fig.2, pos.5) which transmits the motion to the differential through an rotary axis (Fig. 1 pos.7 & fig.2, pos.3) of which is impaled. To be changed different gears, the wheel-gear moves along the rotary axis. When we change between different gears, the multi bevel gear is moved along the axis of the crankshaft. This movement is done by release bearing (fig.1 , pos.2) and a fork lever (fig.1 , pos.3) that moves the bearing along the axis of the crankshaft. The movement of the wheel-gear on the rotary axis is controlled by moving device (Fig. 1 , Pos. 4), which may be a stepper motor with a threaded rod or other type. There is a large number of types of devices that could perform this function. In the absence of classic flywheel, the multi bevel disk can provide this function. From the narrow side of the multi bevel gear may have teeth, that can be used by the classic starter to start the engine. The transmission ratios of the various gears depends on the diameter of the gears, and the diameter of the wheel-gear. The number of the gears is dependent on the diameter of the multi bevel gear and the thickness of the gears. The number of gears reach up 50 or more. They can be used more than one wheel-gears (for example 2 or 3). For example, if we use multi bevel gear with 6 paths, and 3 wheel-gears (with different diameters), there are 3x6 = 18 gears with different ratios.

7. Industrial Applicability:

All the elements of the invention, except the multi bevel gear are available in engineering and are produced by the existing methods. The multi bevel gear itself can be produced as separate bevel gears and to be joined by bolts, rivets or bonding to a metal part, which is essentially a classic flywheel. Alternative production method is making a single homogeneous element

Claims

CLAIMS We claim:

1 . A gearbox comprising " multi bevel gear ", which uses the principle of motion of the bevel gear, but in the gearbox.

- multi bevel gear consists of several bevel gears, one inside the other.

- this gearbox can be used without clutch and flywheel.
