Abstract

The utility model discloses a pedal four-bar driving mechanism which comprises a frame, a pedal, a connecting rod, a rocking bar, a chain wheel, a ratchet flying wheel and the like. The pedal four-bar driving mechanism can be effectively applied in scooters and man-powered pedal machines.

Description

A kind of foot-operated four bar driver trains

Technical field the utility model relates to the mechanical force transmission device, particularly relates to a kind of foot-operated four bar driver trains of scooter.

In the background technology prior art, the disclosure of patent ZL0120311.5 pedal drive mechanism by name patent content, it is made up of pedal, rod member, wheel, it is characterized in that two cover rocker cam mechanisms place the frame both sides respectively, the cam reverse symmetry is on the crank of frame, roller is fixed on the rocking bar, one end of the bar of rocking bar is connected on the frame by jointed shaft, the other end is equipped with pedal, the roller that is contained on the rocking bar can roll along the outline line of cam, this patent structure is made complicated, does not also become commodity widely to utilize.

The summary of the invention the purpose of this utility model provides a kind of simple in structure, cost is low foot-operated four bar driver trains, and it can be effectively used in scooter and the foot-operated machinery of manpower.

The purpose of this utility model is to realize like this, two covers are housed by the jointed shaft that is movably arranged on the frame on the frame, be fixed on last rocking bar isometric on the jointed shaft, following rocking bar, rocking bar in the flexible connection, the connecting rod of following rocking bar, be vertically fixed on the pedal at connecting rod top, be fixed on lever and sprocket wheel on the rocking bar, the spring that lever is connected tension with frame, bicycle freewheel by ratchet in the band of chain connection sprocket wheel, output shaft and the output wheel adorning flywheel and be movably arranged on the frame have been formed four bar driver trains, alternately treadling swings rocking bar in certain angle, can rotate outputting power by same direction by serial transmission driving output shaft and output wheel.

The utility model is because pedal moves up and down along the connecting rod in the four-bar mechanism, thus operate steadily, comfortable, simultaneously owing to adopt the round trip flight of double-stranded wheel driven to take turns outputting power, simple and reliable for structure.

Description of drawings concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the transmission scheme drawing according to the concrete mechanism that the utility model proposes.

Fig. 2 is the birds-eye view of mechanism shown in Figure 1.

Describe details and service condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete mechanism that the utility model proposes.

This mechanism of the specific embodiment comprises by frame 1, is movably arranged on first jointed shaft 6,6 ' on the frame 1, second jointed shaft 14,14 ' is fixedly mounted on first jointed shaft 6, last rocking bar 4,4 ' on 6 ' is fixedly mounted on second jointed shaft 14, following rocking bar 5,5 ' on 14 ', rocking bar 4 in the flexible connection, 4 ' and the connecting rod 3,3 ' of following rocking bar 5,5 ', be vertically fixed on connecting rod 3, pedal 2,2 ' on 3 ' is fixed on rocking bar 4, lever 7 on 4 ', 7 ' and sprocket wheel 10,10 ', with lever 7,7 ' is connected the spring 8 of tension with frame, 8 ', by chain 11,11 ' connects sprocket wheel 10, the flywheel 12 of ratchet in 10 ' the band, 12 ' the four bar driver trains of forming alternately treadle and 2,2 ' can pass through connecting rod 3,3 ', last rocking bar 4,4 ', following rocking bar 5,5 ' makes sprocket wheel 10,10 ' rotates, and by chain 11,11 ', flywheel 12,12 ' drives output shaft 13 and output wheel 9 outputting powers, not firmly at pedal 2, in the time of on 2 ', spring 8,8 ' can pass through lever 7,7 ' makes pedal 2, and 2 ' sets back.Lever 7,7 ' and sprocket wheel 10,10 ' also can be installed in down rocking bar 14, on 14 ', this be installed in rocking bar 4,4 ' go up effective equally.
