FIG. 5 is an exploded perspective view showing a pulley and an auxiliary pulley in the power output apparatus according to the present invention. FIG. Sectional view of the pulley and the auxiliary pulley in the power output apparatus according to the present invention.

1 to 6, a power output apparatus according to the present invention includes a main power generator 200 connected to an axis 110 of an engine block 100 to generate electric energy, And an auxiliary power generator 300 connected to the engine block 100 and capable of generating additional electrical energy, and generating electrical energy of higher power.

Here, the auxiliary pulley 6 connected to the auxiliary power generator 300 is installed in a manner that the pulley 2 mounted on the engine block 100 is superimposed on the auxiliary power generator 300 so that the auxiliary power can be generated in parallel while minimizing the damage of the ready- .

A vehicle capable of providing a high output voltage for power according to the present invention includes an engine block 100, a shaft 110 connected to the engine block 100 to rotate, a pulley 2 connected to the shaft 110, A main power generating unit 220 comprising a first alternator 220 connected to the pulley 2 by a belt V1 and a first battery 230 for storing electric energy generated by the first alternator 220, 200); An alternator bracket 4 formed on one side of the engine block 100; A second alternator 320 mounted on the alternator bracket 4 and connected to the pulley 2 by a second belt V2; And a second battery 340 for storing the electricity generated by the power generation of the second alternator 320. [

The main power generator 200 generates 12 V of electricity. In the case of vehicles, passenger cars, utility vehicles, four-wheel drive vehicles, pickup trucks manufactured by domestic domestic automobile manufacturers, 12V 75 ~ 120A is mounted.

When the vehicle uses air conditioner, lighting, etc., the range is about 85A, and when the battery is partially discharged, there is not enough room for charging and consuming.

Furthermore, it is almost impossible to use such electric capacity as a small refrigerator, an outdoor lighting, and a vehicle electric plate for camping.

In order to compensate for this, an auxiliary power generation unit 300 is included.

The auxiliary power generator 300 generates 24 V of electricity. Therefore, it is preferable that the second alternator 320 is for 24v power generation.

The main application vehicle of the present invention is a military vehicle or a motorcycle, and vehicles of this use require a large-capacity electric battery because of an increase in electric use.

The present invention includes the auxiliary power generation unit 300 to sufficiently meet the electricity use capacity.

The auxiliary pulley 6 may be continuously connected to the pulley 2 of the engine block 100 so that the second belt V2 is connected.

The pulley 2 connected to the shaft 110 of the engine block 100 constitutes the main power generator 200 included in the vehicle originally shipped. In the present invention, the auxiliary pulley 6 is connected to the pulley 2, So that the auxiliary power generation unit 300 is driven.

4 to 6, the pulley 2 has a concave fitting groove 22 formed on the front face of the center portion thereof, a boss 21 formed on the rear face thereof to be engaged with the engine block 100, A belt hooking groove 24 is formed so that the belt is engaged.

The fitting groove 22 is coupled with the auxiliary pulley 6 and can be integrally rotated with the pulley 2 and the auxiliary pulley 6.

The auxiliary pulley 6 has a protrusion 63 formed on the rear surface of the pulley 2 in the same manner as the fitting recess 22 of the pulley 2. The groove has a predetermined depth on the front surface of the pulley 2, And the engaging stepped groove 66 is formed at the bottom portion by being pushed to the inside of the projecting portion 63. [

The locking stepped groove 66 is formed in a rectangular shape so that a lock plate 72, which will be described later, is inserted.

A protruding portion 63 is formed at one side of the auxiliary pulley 6 and the protruding portion 63 can be fitted and fitted into the fitting groove 22 of the pulley 2. [

A pad 5 made of a copper plate or other material may be provided between the auxiliary pulley 6 and the pulley 2.

The pad 5 serves to prevent the auxiliary pulley 6 and the pulley 2 from rotating due to friction during the rotation of the auxiliary pulley 6 and the pulley 2.

Preferably, the outer diameter of the auxiliary pulley 6 is formed to a size of the outer diameter in conformity with the ratio for adjusting the generator rotational speed,

The auxiliary pulley 6 is formed two to three times as thick as the pulley 2 so that a plurality of belt grooves 62 are formed to connect the plurality of belts V2.

Therefore, the plurality of belts V2 can be used to drive the plurality of second alternators 320, thereby enabling high output voltage generation.

On the other hand, a plurality of bolts are arranged on the bottom surface of the auxiliary pulley 6 in the circumferential direction and screwed to the pulley 2 so that the pulley 2 and the auxiliary pulley 6 can rotate without slippage during rotation.

In order to further increase the fastening force, the pulley 2 and the auxiliary pulley 6 are fastened to each other using a separate fastening means T at the center.

The fastening means includes a lock plate 72 inserted into the fastening stepped groove 66 of the auxiliary pulley 6 and a fastening stepped groove 72 penetrating through the lock plate 72 and passing through the projecting portion of the auxiliary pulley 6, As shown in Fig.

Therefore, the crank bolt 71 and the lock plate 72 are engaged to prevent the fixing bolts of the pulley 2 from being loosened.

 The lock plate 72 is a rectangular plate member and has a crank bolt 71 at the center thereof and a locking stepped groove 66 formed on one surface of the pulley 2 or the auxiliary pulley 6, As shown in FIG.

On the other hand, in order to increase the coupling force between the pulley 2 and the auxiliary pulley 6, an adhesive filler may be applied between the auxiliary pulley 6 and the pulley 2 to form the filling layer P ).

The adhesive filler is an epoxy resin, and the hardening of the epoxy resin can firmly integrate the pulley 2 and the auxiliary pulley 6.

Alternatively, the adhesive filler is made by mixing titanium, aluminum, and duralumin in a high-strength liquid adhesive.

The auxiliary pulley 6 and the pulley 2 are formed with grooves (not shown) on one surface thereof, so that the adhesive filler is filled in the grooves to provide a stronger fixing force.

According to an embodiment of the present invention, the joint part 402 of the alternator is coupled to the alternator bracket 4, and the distance between the second alternator 320 and the engine block 100 is adjusted, And a tension adjusting unit 500 for adjusting the tension of the tension member 500.

1 to 3, the tension adjusting unit 500 includes a slot 520 formed at one side of the alternator bracket 4 and a shaft bolt 541 passing through the slot 520 And the shaft bolt 541 is coupled to the coupling part 402 provided outside the second alternator 320. [

The second alternator 320 is symmetrically formed on the outer side of the second alternator 320 so that the fastening portions 402 are disposed at both ends of the alternator bracket 4 and are fastened to the respective shaft bolts 541 and 542 .

By tightening the shaft bolts 541 and 542, the shaft bolt 541 coupled to the elongated hole 520 is loosened and loosened, and then the alternator (more precisely, the second alternator) rotates about the other shaft bolts 541 and 542 So that the spacing of the second belt V2 can be easily adjusted.

A bolt 541 passing through the elongated hole 520 penetrates through one side of the fixing block 522 and is screwed into the screw hole 521 of the alternator bracket 4, .

Further, an adjustment bolt 524 screwed to the side of the alternator bracket 4 is threaded through the other side of the fixing block 522.

Accordingly, when the adjusting bolt 524 is tightened or loosened, the fixing block 522 is moved forward or backward so that it can be moved in the slot 520. In addition, the shaft bolt 541 is moved, and the second alternator 320 is moved, A predetermined distance movement can be performed in the slot 520 with respect to the lower axial bolt 542. [

1, the tension of the second belt V2 may be loosened or strained by moving the shaft bolt 541 of the second alternator 320 to the left or right in the slot 520, When the tension of the second belt V2 is loosened due to long use, the tension bolts 541 and 542 are loosened and moved along the slot 520 to adjust the tension so that the second belt V2 is tightened.

On the other hand, as shown in FIG. 2, the tension adjusting unit 500 includes a cam roller 600 installed to be supported on a part of the second belt V2.

The second belt V2 is supported on the outer circumferential surface of the cam roller 600 while the second belt V2 is pushed by a constant force to provide tension.

The cam roller 600 itself includes an interval adjustment function so that the second belt V2 can be actively spaced within a proper range by the force supported by the second belt V2.

That is, the cam roller 600 is formed with a belt groove 610 so that the second belt V2 is inserted into the outer circumferential surface thereof, a through hole 650 is formed in the center portion thereof, And an elastic body 640 which is eccentrically coupled with the through hole 650 and has one end supported by the inner circumferential surface of the through hole 650 and the other end connected to be supported by the camshaft 630.

Therefore, when the second belt V2 is rotated, the cam roller 600 supported thereon is also rotated.

During this rotation drive, the impact caused by the vertical fluctuation of the second belt V2 is applied to the cam roller 600, and the cam roller 600 also moves up and down.

That is, a space 650 is formed between the camshaft 630 and the inner circumferential surface of the cam roller 600, so that the cam roller 600 can move within the space 650, The movement of the cam roller 600 is always supported by the elastic body 640 so that the cam roller 600 can return to its original state.

Therefore, the second belt V2 is constantly pressed by the cam roller 600 at an appropriate force to be able to be rotated in a taut state, and striking can be prevented.

While the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
