Between using interference fit type connect.
The utility model compared with prior art, remarkable advantage：
(1) driving wheel of the utility model is in close contact with each from wheel, in driving wheel rotation, dependence and driven wheel
Between mutual extrusion and be relatively moved to form frictional force, so that driven wheel be driven to rotate；Active wheel drive can be realized can also be real
Existing driven wheel drive.
(2) elastic mechanism between the driven wheel of the utility model effectively can be compressed and be stretched, can be to greatest extent
Damping, limiting slot increases the flexibility of driven wheel.
(3) V-type contact surface increases driving wheel and driven wheel tread, provides forwardly and upwardly dual for driven wheel
Driving force, so that driven wheel carries out revolution and rotation.
The utility model is described in further detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the double drive wheel of the utility model climbing stairs.
Fig. 2 is the side view of the double drive wheel of the utility model climbing stairs.
Specific embodiment
In order to illustrate the technical solution of the utility model and technical purpose, with reference to the accompanying drawing and specific embodiment is to this reality
It is described further with novel.
A kind of double drive wheel of climbing stairs, including the driven wheel 3 of supporting plate 2, three of driving wheel 1, two；The driving wheel 1
Positioned at center, described two 2 parallel sleeves of supporting plate are in the shaft of 1 two sides of driving wheel；There are three arcs for equidistant setting on the supporting plate 2
Shape limiting slot 4, the center of circle of three limiting slots 4 and the center of circle of driving wheel 1 are concentric；The shaft of three driven wheels 3 is respectively set
In three limiting slots 4；1 inside and outside circle of driving wheel is equipped with v-depression；The outer circle of the driven wheel 3 is located at driving wheel 1
In groove；So that driving wheel 1 and each driven wheel 3 are in close contact；The driving wheel 1 or driven wheel 3 are at least one for elasticity
Wheel is connected between driving wheel 1 and driven wheel 3 using interference fit type.By the connection type of elasticity interference fit, actively
When 1 rotation of wheel, mutual extrusion and it is relatively moved to form frictional force between dependence and driven wheel 3, V-type contact surface makes driving wheel 1
Increase with 3 contact surface of driven wheel, so that driven wheel 3 be driven to rotate, provides double drive power forwardly and upwardly for driven wheel, from
And driven wheel 3 is made to carry out revolution and rotation.
Further, three driven wheels, 3 size is identical, three driven wheels do not stress state when, between any two with master
