It characterized in that it comprises a transmission for transmitting to the drive shaft.

Hereinafter, a driving apparatus using a lever according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

1 is a plan view of a drive device according to the present invention, Figure 2 is a side view of the drive device according to the present invention, Figure 3 is a cross-sectional view showing the configuration of a piston-type lever assembly employed in the present invention.

First, as shown in Figures 1 and 2, in a preferred embodiment of the present invention by increasing the small force obtained by the manpower or a small electric motor with a large force, and then using the increased force to the required torque or rotational speed As a means of obtaining, the principle of lever was used.

To this end, the vehicle body 2 is equipped with a crankshaft 4 'consisting of a plurality of cranks 4, and a small force generated through the crankshaft 4' is transmitted rearward through the lever assembly. Meanwhile, one-way rotary bearings 10-1 and 10-2 which rotate in only one direction are respectively at one end of the cylinders 12-1 and 12-2; 12'-1 and 12'-2 constituting the lever assembly. '1-1, 10'-2 are attached, and when the lever assembly moves up and down by the rotation of the crankshaft 4', the one-way rotation bearings 10-1 and 10-2 are moved up and down by the lever assembly. 10'1-1 and 10'-2 rotate the first transmission shaft 20 while rotating in one direction. Now, the rotational force of the crankshaft 4 'input to the first transmission shaft 20 is transmitted to the drive shaft 28 via a plurality of transmission shafts 22, 24, and 26 in order to rotate it, and the drive shaft 28 Both ends of the drive) is equipped with a driving wheel 30 to enable driving or by connecting various accessories to obtain the necessary power. On the other hand, the vehicle body 2 is rotatably mounted with the driven shaft 28 'in which the driven wheel 30' is mounted at a position spaced apart from the drive shaft 28.

As described above, in the driving apparatus of the present invention using the lever principle, the crankshaft 4 'is composed of a plurality of cranks 4, and pedals 6 and 6' are attached to the cranks 4. In addition, when a small electric motor is connected to the crank 4 instead of the pedals 6 and 6 ', it becomes an electric drive which drives the drive of this invention with electric power. Each crank 4 of the crankshaft 4 'has a rod 14-1, 14-2; 14'- constituting a lever assembly via connecting rings 8, 8'; 9, 9 ', respectively. 1, 14'-2) are combined.

On the other hand, the lever assembly employed in the present invention with reference to Figure 3 one end is connected to the crank 4 of the crankshaft (4 ') via a connecting ring (8') and the other end is a one-way rotation bearing (10-1) 10-2; 10'1-1 and 10'-2 are connected to the first transmission shaft 20. In more detail, the lever assembly has a plurality of oilless bearings 12-1a therein, one end of which is connected to a cylinder 12-1 connected to the one-way rotary bearing 10-1, A rod 14-1, one end of which is inserted into the cylinder 12-1 in a state supported by the oilless bearing 12-1a, and the other end is operatively connected to the crank 4 through the connecting ring 8 '. )

Therefore, when a person steps on the pedals 6 and 6 'by manpower or rotates the crankshaft 4' by a small electric motor, the rod 14- connected to the crank 4 through the connecting ring 8 '. 1) moves in the longitudinal direction along the inner wall of the cylinder 12-1, causing simultaneous movement in the vertical direction. This up and down movement is transmitted to the one-way bearing 10-1 installed at one end through the cylinder 12-1 to rotate the first transmission shaft 20. Here, the one-way bearing 10-1 is to transmit the power only in one direction by the internal one-way clutch mechanism and to freely move when rotating in the opposite direction so as not to rotate, and is known in the art. Detailed illustration and description are omitted.

1 and 2 again, a transmission box 40 is installed in the vehicle body 2 via a bracket 42. The lever box 40 and the first transmission shaft 20 are installed in the transmission box 40. As shown in FIG. A transmission device for increasing the rotational force of the crankshaft 4 'transmitted through the transmission shaft 28 is embedded.

The gearbox may have a gear train structure of a multi-stage gear chain that connects and transfers a multi-gear gear by connecting a plurality of gears and a multi-stage gear through a chain, but in the preferred embodiment of the present invention, Adopted.

To this end, the transmission box 40 is rotatably mounted to the first to fourth transmission shafts (20, 22, 24, 26) constituting the transmission, of which, in the first transmission shaft (20) The first gear G1 is rotated in one direction by the rotational force of the pedal transmitted from the lever assembly through the one-way rotating bearings 10-1, 2; 10'-1, 2, and the second transmission shaft 22 ), Along with the second gear (G2) receiving the rotational force transmitted through the first gear (G1), the third gear (G3) is provided coaxially. In addition, a fifth gear G5 is coaxially installed on the third transmission shaft 24 together with a fourth gear G4 that receives the rotational force transmitted through the third gear G3, and the fourth transmission shaft 4 is coaxially provided. In addition to the sixth gear G6 receiving the rotational force transmitted through the fifth gear G4 on the shaft 26, the seventh gear G7 transmitting the rotational force to the drive gear G8 installed on the drive shaft 28. ) Is installed coaxially.

Thus, as described above, the small forces transmitted from the crankshaft 4 'via the lever assembly and the one-way rotating bearings 10-1, 10-2; 10'1-1, 10'-2, in turn, The first gear G1 of the first transmission shaft 20 and the second gear G2 of the second transmission shaft 22 are transferred to the second transmission shaft 22 to increase the first speed. It is secondly increased while being transferred to the third transmission shaft 24 through the third gear G3 of the second transmission shaft 22 and the fourth gear G4 of the third transmission shaft 24. In the same principle, the increased force is transmitted to the fourth transmission shaft 26 through the fifth gear G5 of the third transmission shaft 24 and the sixth gear G6 of the fourth transmission shaft 26. The third gear is accelerated to the driving shaft 28 while being transmitted to the driving shaft 28 through the seventh gear G7 of the fourth transmission shaft 26 and the driving gear G8 of the driving shaft 28. Great power is transmitted.

At this time, driving wheels 30 and driven wheels 30 'are mounted at both ends of the drive shaft 28 and the driven shaft 28', and the vehicle body 2 is driven by the rotation of these wheels 30 and 30 '. This becomes possible.

On the other hand, it is preferable that both ends of the crankshaft 4 'and the many transmission shafts 20, 22, 24, and 26 are rotatably mounted to the vehicle body via the bearing bearing 32, respectively.

According to the present invention described above, the small force obtained by the manpower or the small electric motor is amplified to a large force by using the principle of the lever, and then the power is increased by increasing the force again through the transmission. The same advantage can be obtained.

First, since it does not use a conventional engine as a power generator can not only reduce the energy required to carry the weight of the engine itself, but also save the purchase cost and maintenance costs required for maintenance of the engine purchase.

Secondly, since the driving device of the present invention can be operated using a small electric motor having a small amount of manpower or power consumption, it is possible to greatly reduce the consumption of fossil fuels, to prevent waste of resources, and to reduce transportation and logistics costs.

Third, it is possible to contribute to the improvement of the profitability of the economically small operators by making a means of transportation at low cost, and in particular, it is possible to produce and disseminate the scooter, which is a means of walking for the disabled at a low price, to improve the welfare of the disabled.

Fourth, by reducing the use of fossil fuels such as gasoline, kerosene and LPG, it is possible to prevent global warming and reduce environmental pollution to maintain a clean environment.
