| 摘要 |
The present invention is directed to a drive apparatus using a principle of lever, in which a little force from a manual labor or an electric motor is changed into an increased force with a lever assembly, and this increased force is again converted into a more increased force by means of a speed hanger, and thereby obtaining a required power. The drive apparatus comprises a crank shaft (4) consisting of a plurality of cranks (4); a frame (2) rotatably mounted with a plurality of transmitting shafts (20, 22, 24, 26) and at least one drive shaft (28), including the crank shaft (4); a lever assembly connected to the cranks (4) of the crank shaft (4) by way of a coupling ring on one end and connected to one (20) of the transmitting shafts by way of a plurality of one-way rotating bearings (10-1, 10-2; 10 -1, 10 -2) on the other end; and a speed changer increasing and transmitting a rotating force from the crank shaft (4) via the lever assembly to the at least one drive shaft (28). |
