Description

[0001] The present invention relates to a driving unit for driving a vehicle using a freewheel,

The present invention relates to a board (so-called quickboard), and more particularly, to a driving unit for driving using a freewheel which continuously rotates a driving wheel through only pressing operation of a foot member and outputs a large driving force even with a small force ≪ / RTI >

The driving quick board of the running product is used as a moving machine, a riding machine, or a transportation means for moving purposes, and a method of using a crankshaft by various methods of rotating a driving shaft, a method of using a rack and a pinion, a method using an electric motor or an engine .

In this case, a bicycle that rotates the drive shaft by manual operation of the user has a disadvantage that the pair of pedals must be rotated 360 degrees. In rotating the crankshaft or the like, the crankshaft arm has a short length, Even if the diameter of the wheel is small and a large number of revolutions are not generated, the speed of the quick board is short because the forward distance is short and there is a lot of problems in traveling. To solve such a problem, there is a patent document (Patent No. 10-1746061) which is patented by the present applicant.

The patent document includes a frame; A handle mounted on the frame; A foot member provided on the frame; A first connecting rod hinged to an upper end of the foot member to convert one side seesaw drive of the foot member into a linear motion; And the upper end portion is hinged to the foot member to turn the other side seesaw drive of the foot member into a linear motion,

Load; A first freewheel rotating in both directions by a linear movement of the first connecting rod, the first freewheel generating a rotating force while being lowered by pressing one side of the foot plate member and maintaining a free state when the first connecting rod descends; A second freewheel rotating in both directions by a linear movement of the second connecting rod, the second freewheel generating a rotating force while descending due to the pressing of the other side of the foot member, A shaft portion connected to the center of the first and second freewheels and a hinge connection portion eccentrically formed from the shaft portion and connected to the first and second connecting rods, A freewheel shaft for rotating the respective freewheels; A drive wheel connected directly or indirectly to the first freewheel and the second freewheel and rotated 360 degrees in a forward direction by alternately receiving rotational force from the first freewheel and the second freewheel; A plurality of power transmission means for increasing and transmitting the rotation of the driving wheel; And a drive wheel installed on the frame and being driven to receive a rotational force from the power transmission means. The first and second freewheels are driven by a seesaw motion of the board or a seesaw motion of the first and second pedals, The driving wheel is continuously rotated in the advancing direction while rotating only within a certain angle, so that no stall occurs during operation of the board and the pedal, thereby ensuring smooth driving performance, and further increasing the number of revolutions of the driving wheel to be transmitted to the driving wheels It is possible to increase the speed without increasing the size of the driving wheel. As a result, it is possible to feel a great driving force and speed feeling. However, the connecting rod is close to the axis of the freewheel to limit the gain of the driving force. It is very difficult and difficult to travel only by the force, Only the free mothamyeo commercialized by direct drive is directly connected to, the manufacture of the freewheel shaft for the installation of the connecting rod mothada good productivity difficult.
