The speed changing structure that gear ring engages with ring gear, chaindriven defect is overcome, had fashionable, simple in construction, firm reliable
And the advantages of transmission efficiency.
Realizing the concrete technical scheme of the utility model purpose is：
A kind of drive mechanism of Chainless bicycle, its feature include vehicle frame, pedal disk, the first crank, the second crank, company
Bar and wheel；
Crank shaft, the first crank axle and axletree are respectively equipped with the vehicle frame；The pedal disk be provided with ring gear and
The disc in axle center, a pair of pedals are connected with its axle center；First crank is the disc provided with centre bore and external toothing,
Deviation disk center is provided with the first crank-pin in card；Second crank is disc, and deviation disk center is provided with card
Second crank-pin；Connecting rod is the rod member that both ends are provided with axis hole；The axle center of wheel is provided with connecting seat；
The axle center of the pedal disk is fixed on the crank shaft of vehicle frame, and the first crank is articulated with the first crank axle through centre bore
On, and the external toothing of the first crank engages with the ring gear of pedal disk, the second crank is coaxially connected with wheel, and the company through wheel
Joint chair is articulated with axletree, and axis hole of the connecting rod through both ends is hingedly connected on the first crank-pin of the first crank and the second crank
The second crank-pin on.
The utility model is driven between pedal disk and wheel using crank connecting link, is adopted between pedal disk and the first crank
The speed changing structure engaged with external toothing with ring gear, chaindriven defect is overcome, had fashionable, simple in construction, firm
The advantages of reliable and transmission efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Refering to Fig. 1, the utility model includes vehicle frame 1, pedal disk 2, the first crank 3, the second crank 4, connecting rod 5 and wheel 6；
Crank shaft 11, the first crank axle 12 and axletree 13 are respectively equipped with the vehicle frame 1；The pedal disk 2 be provided with
Ring gear and the disc in axle center, a pair of pedals 21 are connected with its axle center；First crank 3 is provided with centre bore and external tooth
The disc of circle, deviation disk center is provided with the first crank-pin 31 in card；Second crank 4 is disc, in card partially
The second crank-pin 41 is provided with from disc centre；Connecting rod 5 is the rod member that both ends are provided with axis hole；The axle center of wheel 6 is provided with connecting seat；
The axle center of the pedal disk 2 is fixed on the crank shaft 11 of vehicle frame 1, and the first crank 3 is articulated with first through centre bore
On crank axle 12, and the external toothing of the first crank 3 engages with the ring gear of pedal disk 2, and the second crank 4 is coaxially connected with wheel 6,
And the connecting seat through wheel 6 is articulated with axletree 13, axis hole of the connecting rod 5 through both ends is hingedly connected to the first of the first crank 3
On crank-pin 31 and on the second crank-pin 41 of the second crank 4.
The utility model so uses：
Assembling of the present utility model
Refering to Fig. 1, the utility model only further illustrates to drive part, eliminates the front-wheel and its remaining part on vehicle frame 1
Point.A pair of pedals 21 are connected with the axle center of pedal disk 2 of the present utility model, by the axle center of pedal disk 2 and the crank shaft of vehicle frame 1
11 are connected；First crank 3 is articulated with the first crank axle 12 of vehicle frame 1 through centre bore, and make the external toothing of the first crank 3 with
The ring gear engagement of pedal disk 2；The connecting seat of the disc centre of second crank 4 and wheel 6 is coaxial and be connected and bent by second
Handle 4 is articulated with the axletree 13 of vehicle frame 1 together with wheel 6 through connecting seat；Axis hole of the connecting rod 5 through both ends is hingedly connected to first
On first crank-pin 31 of crank 3 and on the second crank-pin 41 of the second crank 4, the utility model assembling finishes.
It is of the present utility model to ride
Refering to Fig. 1, bicyclist imposes on external force on a pair of pedals 21, and driving pedal disk 2 rotates, due in pedal disk 2
Gear ring engages with the external toothing of the first crank 3, and pedal disk 2 drives the first crank 3 to rotate, due to the first crank of the first crank 3
It is hinged on pin 31 and on the second crank-pin 41 of the second crank 4 and second crank 4 is driven by connecting rod 5 by connecting rod 5, the first crank 3
Rotate, then because the second crank 4 is coaxially connected with wheel 6, and the connecting seat through wheel 6 is articulated with axletree 13, the second song
Handle 4 and the synchronous axial system of wheel 6, so as to realize by driving pedal disk 2 to be rotated with motor car wheel 6, complete the purpose ridden.
The utility model is driven using crank connecting link, and the power of pedal disk 2 is delivered into wheel 6, realizes no chain drive；
Using external toothing and ring gear meshed gears speed changing structure between the crank 3 of pedal disk 2 and first, by the tooth for changing gear ring
Number ratio, thus it is possible to vary the fast ratio ridden, the utility model overcome chaindriven defect, have laborsaving, safe and reliable and are driven
The advantages of efficiency high.
