Description

Wheel

Technical field

The utility model relates to a kind of wheel.Be the wheel on various bicycles and the various self-propelled vehicle specifically.

Background technology

Up to now, no matter be manpower bicycle, or self-propelled vehicle, all be to drive the center shaft rotation of wheel by propulsion source and transmission device, thereby realize wheel.Rotate owing to drive the center shaft of wheel by propulsion source and transmission device, center shaft is a dynamical axis.During work, dynamical axis receives the edge that is radiated wheel behind the power again.According to the lever principle on the mechanics, dynamical axis is a fulcrum, the wheel outer edge is a stress point, fulcrum is more little to the distance of stress point, and required power is just more little, and the conventional wheel dynamical axis be fulcrum to the wheel outer edge is that distance between stress point is far away, resistance is big, inertia is little, and the power that needs is big, and consumes energy is many.

The utility model content

Problem to be solved in the utility model provides a kind of wheel.This wheel, resistance is little, and inertia is big, and the power that needs is few, saves the energy.

For addressing the above problem, the utility model is taked following scheme:

Wheel of the present utility model comprises wheel hub, and centre hole is arranged on the wheel hub, has center shaft and the two to be movable in the centre hole and cooperates.Wheel disc and outer rim in said wheel hub contains during its characteristics, on the cylindrical of interior wheel disc pit is arranged, on the hole wall of pit axial hole is arranged, dynamic axle and gear between two axial holees of same pit, gear is fixed on the centre of dynamical axis, the dynamical axis two ends by bearing installation in two axial holees.On the circle gear ring is arranged in the outer rim, said gear protrudes outside pit and is meshed with gear ring on the circle in the outer rim.

The cylindrical width of interior wheel disc equates with axial chimb, and between the cylindrical both sides of the both sides of axial chimb and interior wheel disc annular cover plate arranged all, the both sides of this annular cover plate respectively with the both sides of axial chimb and the cylindrical both sides sealing-in mutually of interior wheel disc.

Between two annular cover plates and outer rim minor axis is arranged, this minor axis is connected with annular cover plate and outer rim respectively mutually near interior wheel disc and its two are short, is with bearing on it, the ball on the bearing and interior wheel disc cylindrical contact.

Said outer rim is made up of main circle and auxilliary circle, and axially chimb is in main circle cylindrical both sides.Circle equates in the axial chimb on the outside diameter of auxilliary circle and the main circle, and auxilliary circle is fixed on a side shaft that the master encloses in chimb.On the interior circle of auxilliary circle internally toothed annulus is arranged, its diameter is less than main circle, and with gear mesh together.

Take such scheme, have the following advantages:

Because wheel disc and outer rim in the wheel hub of the utility model wheel contains, on the cylindrical of interior wheel disc pit is arranged, on the hole wall of pit axial hole is arranged, dynamic axle and gear between two axial holees of same pit, gear is fixed on the centre of dynamical axis, the dynamical axis two ends by bearing installation in two axial holees; On the circle gear ring is arranged in the outer rim, said gear protrudes outside pit and is meshed with gear ring on the circle in the outer rim.When with the rotation of drive power source gear, can be by the rotation of gear driven outer rim, dynamical axis wherein is equivalent to the fulcrum of lever, and itself and wheel outer edge are that the distance between stress point only is 1/3rd of a conventional wheel.According to mechanics principle, fulcrum is more little to the distance of stress point, and required power is just more little, is that distance between stress point is shorter because the utility model wheel dynamical axis is a fulcrum to the wheel outer edge, and resistance is less, and inertia is big, and therefore the power that needs is little, can save the energy.

In addition, under installing condition, gear is positioned at and 45 degree angles, ground,, just can makes wheel revolutions as long as follow little power when starting, for one of wheel.So, but also saving in power, save the energy.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, wheel of the present utility model comprises wheel hub, wheel disc 1 and outer rim in this wheel hub contains.Interior wheel disc 1 wherein is formed by connecting by pin 10 by two, and its intermediate thin, edge are thick, and is the stream line pattern transition from its center to the edge, is processed with central shaft hole on it, and center shaft 2 is installed in the central shaft hole, and

center shaft

2 and 1 on interior wheel disc are heavy keying fit.For ease of reversing, also can between the centre hole of center shaft 2 and interior wheel disc 1, bearing be installed.Be processed with a pit on interior wheel disc 1 cylindrical, with all be processed with axial hole on two hole walls of axially vertical pit, be provided with dynamical axis 9 and gear 3 between two axial holees, be processed with centre hole on the gear 3, gear 3 is fixed on the centre of dynamical axis 9 by this centre hole, dynamical axis 9 two ends then by bearing installation in two axial holees.Be processed with gear ring on the circle in the outer rim, said gear 3 protrude outside pit and with outer rim in gear ring on the circle mesh together.

See Fig. 1, when wheel of the present utility model is used on bicycle or the self-propelled vehicle, need to process axial chimb that axially all there is crimping in opposite directions at the chimb edge, and overlaps a tire 6 by this crimping on outer rim in outer rim cylindrical both sides.

As shown in Figure 4, when being used on the railroad vehicles such as train, urban light rail when wheel of the present utility model, chimb got final product outside only need were processed radially on the periphery in the outside of outer rim.

The cylindrical width of interior wheel disc 1 equates with the axial chimb width of outer rim cylindrical both sides, and between the cylindrical both sides of the both sides of axial chimb and interior wheel disc 1, be provided with annular cover plate 11, this annular cover plate outward, interior both sides respectively and be detachable shape between the cylindrical both sides of the axial chimb both sides of outer rim and interior wheel disc 1 and connect.

For improving the inertia of the utility model wheel, between two annular cover plates 11 and outer rim, be respectively arranged with eight minor axises 7, these eight minor axises are evenly arranged along the circumferencial direction of outer rim.With all be processed with axis hole accordingly on eight minor axises, the 7 corresponding outer rims He on two annular cover plates 11, minor axis 7 penetrates in this axis hole, and minor axis 7 two ends are separately fixed in the corresponding axis hole of two annular cover plates 11.All be with bearing 4 on the minor axis 7 of outer rim both sides, the ball on the bearing 4 contacts with the cylindrical of interior wheel disc 1.

For ease of assembling, said outer rim can be made up of main circle 5 and one an auxilliary circle 8.Axial chimb wherein is in main circle 5 cylindrical both sides.Circular diameter equates in the axial chimb on the outside diameter of auxilliary circle 8 and the main circle 5, and auxilliary circle 8 is fixed on the master by minor axis 7 and encloses a side shaft of 5 in chimb.Be processed into internally toothed annulus on the interior circle of auxilliary circle 8, its diameter encloses 5 less than main, and meshes together with gear 3.
