Support member.Wheel is a kind of critically important parts in vehicular field, play support vehicle, buffer ground impact,
Generate the effect of driving force, brake force.
Currently, most of wheel in the market is circular wheel, circular wheel is in level walking, the axle height of wheel
It is constant, to make wheel that can smoothly be run on level land.But when encountering step, circular wheel is difficult to pass through, vehicle
The supporting effect of wheel is not so good.The utility model is difficult to the characteristics of fast and stable passes through step for common wheel, it is proposed that one
The novel Multifunctional movable pulley of kind.
Utility model content
(1) technical problems to be solved
The technical problems to be solved in the utility model is that wheel how to be allowed also smoothly to be run when encountering step.
(2) technical solution
Encounter the embarrassed shape that step is difficult to steady fast passing to improve current wheel, the utility model provide one kind can on
The Multifunctional movable pulley got out of a predicament or an embarrassing situation, which not only can smoothly walk as common wheel on level land, but also work as
It encounters when wanting up/down steps, can also smoothly advance.
Technical solution used by the utility model is：
It is a kind of can up/down steps Multifunctional movable pulley, including wheel hub, spoke and wheel rim, the spoke include several fixed
Two kinds of long spoke and the scalable spoke of equivalent, the wheel rim are made of the wheel arc equal with spoke quantity, every section wheel arc with
One spoke is corresponding, and two kinds of spokes are arranged alternately, and wheel hub is fixed in fixed length spoke one end, and the other end is hinged with respective wheel arc,
Wheel hub is fixed in scalable spoke one end, and the other end is fixed with respective wheel arc, when scalable spoke is retractable to fixed length spoke etc.
When long, all wheel arcs constitute complete circle wheel rim.In the program, it is preferred that the spoke totally 16 takes turns totally ten six parts of arc,
Adjacent two fixed length spokes are in 45 °, and adjacent two scalable spokes are also in 45 °；The wheel arc to connect with fixed length spoke is typically longer than
The wheel arc to connect with scalable spoke；In addition, tire can be enclosed in the wheel arc extrados, to play cushioning effect；
When practical application, Pneumatic extension device or hydraulic telescopic device may be used in the scalable spoke, and is provided with controller,
The expanding-contracting action of all scalable spokes is uniformly controlled by controller；Aluminium conjunction may be used in wheel hub, spoke and the wheel arc
Gold is made to bear the stress of high intensity.
In level walking, the scalable spoke of the stability based on circular rim, Multifunctional movable pulley elongates, and makes wheel
Circle forms a complete circle wheel rim；When encountering step, the scalable spoke of Multifunctional movable pulley shortens, and outmost turns are only left
Wheel arc equipped with revolute pair, by taking top bar as an example, it is assumed that original state is as shown in Figure 3, it is illustrated that in lower section fixed length spoke be in
Initial step, due to being acted on by power, the center of gravity of wheel moves forward, it is illustrated that in the wheel arc that is connect with adjacent fixed length spoke
It, when taking turns arc with deck contact, will be taken turns with the deck contact to step to a new level since wheel arc with spoke is connected with revolute pair
Arc will be tangent in table top, and due to being acted on by power, axle is moved along, and take turns the revolute pair of arc and can also rotate therewith, finally with
The spoke of arc connection is taken turns perpendicular to ground, as the state of lower section fixed length spoke at this time, so gone down, wheel can be stable
Pass through step.
(3) advantageous effect
Compared with prior art, the utility model has the following advantages：
A kind of Multifunctional movable pulley provided by the utility model, using divisible wheel rim technology, and in wheel arc and spoke
Special processing has been done in connection, wheel can be allowed smoothly to advance on step.It can be as common wheel at level land
Smoothly operation, when encountering step, can also be passed through, and simple in structure using the special construction of itself, easy to operate,
It is highly practical.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is not intended to limit the scope of the present invention for illustrating the utility model.
In the description of the present invention, it should be noted that this wheel can not be on the level land described in level walking
Gentle ground, but relative to the ground of not step, on acclive level land, the utility model equally can be stable
It advances.
As shown in Figure 1, Multifunctional movable pulley optimizes on the basis of circular wheel, as shown in Fig. 2, multi-functional
Movable pulley is made of three parts, including wheel hub, spoke and wheel rim, the spoke include several fixed length spokes 3 and equivalent can
Flexible 4 two kinds of spoke, the wheel rim are made of the wheel arc equal with spoke quantity, and every section of wheel arc is corresponding with a spoke,
Two kinds of spokes are arranged alternately, and wheel hub is fixed in fixed length spoke one end, and the other end is hinged with respective wheel arc 1, scalable spoke one end
Be fixed on wheel hub, the other end is fixed with respective wheel arc 2, when scalable spoke is retractable to it is isometric with fixed length spoke when, all wheel arcs
Constitute complete circle wheel rim.
Solid tyre is housed in the wheel rim outermost of wheel, the effect of bumper and absorbing shock can be played, which can be by
Tire set on every section of wheel arc extrados is constituted.
In order to which wheel can advance on level land, using telescopic spoke, at level land, telescopic spoke is stretched
It is long, so that wheel arc is contacted with each other, forms wheel rim and fixation, such as Fig. 2 states, circular wheel rim can smoothly advance on level land.
In order to enable wheel smoothly to advance on step, it is connected in such a way that wheel arc and spoke are by revolute pair, often
It is separated by 45 ° between two spokes equipped with revolute pair, when encountering step, telescopic spoke is retracted, and is fixed,
Eventually form the state such as Fig. 3.Fig. 4 is the part drawing of revolute pair part.Flexible rung sections are retracted, and revolute pair part is made
Wheel arc and scalable rung sections wheel arc separation.When the only wheel arc of revolute pair part, next wheel with deck contact
Arc will be become horizontal by the effect of the power on ground, and the moment keeps wheel arc and table top tangent, and such multifunctional wheel can be light
And stable climb steps.Fig. 5 is the wheel arc being connected directly with scalable spoke, when encounter step need retraction when, disc portion
Point coaxial injector increases and fix, eventually forms such as Fig. 3, makes the wheel rim part only remaining wheel arc that revolute pair is housed.
Pneumatically or hydraulically telescopic rod can be used in the scalable spoke of the Multifunctional movable pulley, is uniformly controlled by controller all
The expanding-contracting action of scalable spoke.The utility model is simple in structure, easily manufactured, can top bar and in level walking simultaneously, and
The two conversion is simple.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, all in this reality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should all be included in the utility model
Within protection domain.
