Crank shafts arranged at both ends of the power shaft respectively and oppositely are hinged at one end of a connecting rod, another end is hinged on a connecting body of a movable pulley block, and the lower part of a coaxial perpendicular of the movable pulley block is provided with a fixed pulley block. The crank shafts wind around the two pulley blocks through wire ropes, and the leading out end is provided with a foot pedaling pedal. The utility model has the advantages that design is reasonable, driving force is large, and the utility model is suitable to be arranged at a non-motor vehicle or a large-sized sport toy for driving devices.

Description

Wheel shaft power device

The utility model relates to a kind of wheel shaft power device that is used for non-power-driven vehicle and large-scale sport toy load weight.

In the known disclosed technology, general rickshaw mostly is the mono-chain gear, and because of the transmitting ratio of this driving device is little, propulsive effort need be made circular movement, so effort, transmission speed is slow, load is light.

The purpose of this utility model is for solving the problem that above-mentioned technology exists, and the unpowered vehicle dynamic equipment that a kind of drive configuration is reasonable, laborsaving, quick, load is heavy is provided.

For achieving the above object, technical solution of the present utility model is finished like this: wheel shaft power device, it comprises floral disc, and by on the floral disc siamesed dynamical axis flywheel being housed also, one end of the bent axle articulated linkage that its dynamical axis two ends are oppositely arranged respectively, the connecting rod other end are hinged on the connector of running block, with the coaxial vertical line bottom of running block the fixed pulley group are set, be wrapped on two assembly pulleys by steel rope, make its exit be provided with the foot-operated formation of pedaling.

The technical solution of the utility model also comprises: be the allocation ratio of arranging the two groups of trains of two groups of movable and fixed pulley groups that are provided with up and down and should be 2: 1 at least.

The utility model characteristics compared to existing technology are, wheel shaft power device, and it has reasonable in design, and fitting operation is easy, adopts heat-resisting, wear-resisting, resistant to corrosion to cook nylon material and make more, promptly saves steel, but expendable weight again; In on the one hand the key of this device be by linear relative movement more easily, export the big power of strong torque, one can raise speed, two can bear a heavy burden, and can be used as the Power Drive Unit that is installed in unpowered vehicle or large-scale sport toy.

Description of drawings:

Fig. 1 is the structural representation of wheel shaft power device.

Fig. 2 is an assembly pulley wheel train structure scheme drawing.

Embodiment does concrete description in conjunction with the accompanying drawings:

By shown in Figure 1, it comprises floral disc 8 wheel shaft power device, by on the floral disc 8 siamesed dynamical axiss 7 flywheel 9 that is used to produce inertia being housed fixedly also, the two ends of dynamical axis 7 are connected with bent axle 6, and be up and down and be oppositely arranged, one end of pivotally attached connecting rod 5 is set on the connecting shaft by bent axle 6, the other end of connecting rod 5 is hinged on the connector of 4 of running blocks, running block 4 is movably arranged on the body by wheel shaft and position straight line shifting movement up and down reciprocatingly, also be provided with fixed pulley group 3 with the bottom of the coaxial vertical line of running block 4, be fixed on the body by wheel shaft, and be wrapped in respectively on running block 4 and the fixed pulley group 3 by steel rope 2, one end of steel rope 2 is fixed in the wheel shaft 5 of fixed pulley group 3, is provided with on another exit and foot-operatedly pedals 1.

See Fig. 2, described assembly pulley train is the two groups of running blocks 4 and the fixed pulley group 3 of arranging by being up and down, and is wound on two groups of assembly pulleys by two steel ropes 2 and combines, and makes steel rope 2 by drawing the drive end as power on two groups of running blocks 4 wherein.

The described allocation ratio that is every group of movable and fixed pulley group of train of arranging up and down should be 2: 1 at least.

During mode of operation, what be provided with about stepping on the underfooting foot-operatedly pedals 1 and alternately steps on and pedal, by steel rope 2 traction running blocks 4, running block 4 whole straight lines are moved down, connector pivotally attached connecting rod 5 on the traction running block 4, also drive simultaneously bent axle 6 and dynamical axis 7, drive floral disc 8 flywheels 9 and make circular movement, output torque.

Claims (2)

1, a kind of wheel shaft power device, comprise floral disc, it is characterized in that, flywheel (9) also is housed on floral disc (8) the siamesed dynamical axis (7), one end of bent axle (6) articulated linkage (5) that its dynamical axis (7) two ends are oppositely arranged respectively, the connecting rod other end is hinged on the connector of running block (4), with the coaxial vertical line bottom of running block (4) fixed pulley group (3) is set, be wrapped on two assembly pulleys by steel rope (2), make its exit be provided with foot-operated pedal (1) and constitute.

2,, it is characterized in that described being arranged two groups of running blocks (4) of being provided with up and down and the allocation ratio of fixed pulley group (3) should be 2: 1 at least by the described wheel shaft power device of claim 1.
