Fig. 2 is the lateral plan according to transmission device of the present invention;
Fig. 3 is the lateral plan of transmission device according to another embodiment of the present invention;
Fig. 4 is the scheme drawing that has assembled the unicycle of transmission device of the present invention.
The specific embodiment
Referring to accompanying drawing, at first referring to Fig. 1 and Fig. 2, wherein Fig. 1 illustrates the front elevation of transmission device according to a preferred embodiment of the invention, and Fig. 2 illustrates the lateral plan of this transmission device.This transmission device comprises the crank 6,8 that has pedal 14, and is connected respectively to the left and right side Power train on described crank 6,8 and the flower wheel 12.Described crank 6,8 is arranged to rotate with opposite phases.
The right side power transmitting mechanism comprises that one is connected sprocket wheel 20 on the crank 6, another chain 28 that is connected the sprocket wheel 24 on the flower wheel 12 and extends around described sprocket wheel 20,24 by axle 18.Axle 18 is installed in rotation in the sleeve pipe, and this sleeve pipe is fixed on the vehicle frame 10 regularly.The structure of left side power transmitting mechanism and the structural similitude of right side power transmitting mechanism, that is, crank 8 is connected with sprocket wheel 22 by axle 18, and wherein said sprocket wheel 22 rotates another sprocket wheel 26 by chain 30, and described sprocket wheel 26 is fixed on the flower wheel 12 regularly.Described sprocket wheel 24 and 26 the relative position of each other are fixed.It may be noted that described flower wheel 12 also can assemble one and allow its free-moving wheel hub, to replace the fixed conveyor of crank 6,8.
More than the principal character of the transmission device of Jie Shaoing is: though the pivot center of crank 6,8 is different, in parallel with the pivot center 16 of wheel 12, and the constant distance between described two pivots center.Distance between the pivot center of pivot center 16 and crank 6,8 is not more than-preferably less than the radius of-wheel 12.As depicted in figs. 1 and 2, the pivot center of crank 6,8 is preferably placed between the pivot center 16 and ground of wheel 12.Certainly, also the pivot center of crank 6,8 can be arranged in pivot center 16 tops.
(not shown) according to another preferred embodiment of the invention, the axle 18 of crank 6,8 can have variable position, and each position of 18 can be adjusted in the lump or individually.In this case, vehicle frame 10 can be formed the position that allow to change axle 18 and axle 18 is fixed on the position of newly adjusting.At one more in the simple example, can by make axle 18 around the pivots center 16 of sprocket wheel 24,26 rotate-promptly by making axle 18 rotate-change the position of axle 18 around the pivots center 16 of wheel 12.But in complicated example, can change distance between the pivot center 16 of the axle 18 of crank 6,8 and wheel 12 by one or more gears of in chain drive, planting.
Fig. 3 illustrates another preferred embodiment according to transmission device of the present invention, wherein the form of left and right side power transmitting mechanism is a gear drive, wherein connecting gear 20f, the 22f of crank 6,8 respectively and connecting power between gear 24f, the 26f of flower wheel 12 and transmitting respectively and realize by intermediate gear 32f, 34f, but not aforementioned chain.As shown in Figure 3, intermediate gear 32f, 34f are rotatably mounted on the vehicle frame 10.According to the size of other gear, the pivot center of intermediate gear 32f, 34f both can intersect with the connection lead of the center of turn of gear 20f, 22f and gear 24f, 26f, also can with described connection lead at a distance of preset distance, as shown in Figure 3.If the gear transmission transfer system of Fig. 3 is placed a housing that is installed on the vehicle frame 10, then intermediate gear 32f, 34f can be installed on the described housing by a sleeve pipe.Similar with chain drive, the axle 18 that is connecting crank 6,8 not only can be arranged together but also can be separated from each other.But clearly,, this power transfer assemblies only can be done as a whole moving because the contact between the gear is rotated around the center of turn of described gear 24f, 26f by making described gear transmission transfer assembly.
