And the utility model discloses then utilize ring flange, transmission shaft and conical gear's effect, control tire deformation mode and the conversion between the mode of going update a comparatively novel deformation wheel mechanism, have the function of climbing the building and going on the level land concurrently through warping, facilitate for climbing the building.

Disclosure of Invention

An object of the utility model is to provide a flexible wheel mechanism, through the conversion of wheel form, make it realize both can walk on the level land, also can be at the technical requirement of walking on the stair that have the step, reach safe and reliable, conversion efficiency is high, convenient operation's effect.

In order to realize the purpose, the following technical scheme is adopted: the utility model relates to a deformation wheel mechanism that can be used to climb building comprises four quarter wheel rims, conical gear A, conical gear B, left flange dish, right flange dish, transmission shaft, shaft coupling, clamp ring.

As the utility model discloses an improvement, the whole rim that can be used to the deformation wheel mechanism of climbing the building divide into the quartering, and a bevel gear B is connected respectively to the semi-axis in every quarter rim to intermeshing between each bevel gear B, the semi-axis end that the rim is connected passes through clamp ring zonulae occludens with the shaft coupling, and the transmission shaft then inlays the cover on the shaft coupling, and a bevel gear A of its end-to-end connection provides the power that advances for whole deformation wheel.

The utility model provides an above-mentioned technical problem's technical scheme as follows: when the vehicle runs on a conventional road surface such as a flat ground, the transmission shaft (6) moves to the left, is disconnected with the bevel gear A (7) on the transmission shaft and is not deformed, the right flange (3) and the left flange (5) are separated, the operation of the transmission shaft (6) is not influenced by the bevel gear A (7) and the bevel gear B (2), and the flat key (13) is matched with the key slot on the transmission shaft and has the same working principle as that of a common wheel. When meeting the ground with steps, transmission shaft (6) move to the right, right flange (3) and left flange (5) laminating, thereby steerable bevel gear A (7) rotate, bevel gear A (7) and other four identical bevel gear B (2) intermeshing, when transmission shaft (6) take place to rotate, its bevel gear A (7) just can rotate along with it, thereby the deformation of drive rim (1), and the angle that each rim (1) warp is the same, after reaching 90 degrees deformations, transmission shaft (6) move to the left, right flange (3) and left flange (5) separation, bevel gear B (2) and bevel gear A (7) reciprocal anchorage, stop the deformation. The deformed wheels are matched with the step angles, so that the stair climbing action is realized.

Compared with the prior art, the beneficial effects of the utility model are that: the deformation is flexible and stable. The deformation wheel can drive the rotation and the meshing of four identical conical gears B on the wheel shaft only by the rotation of the conical gear A on the main shaft, so that the deformation efficiency is greatly improved, and the conical gear has good stability during meshing operation, thereby greatly improving the safety factor of the deformation wheel.

The bearing weight is great. The main mechanism of the deformation wheel is the mutual meshing between the conical gear A and the conical gear B, and compared with the common gear, the conical gear has higher load bearing capacity, so that the bearing capacity of the deformation wheel is improved.

The price is low. The deformation wheel is simple in mechanism, does not have complex parts, is all conventional parts, can be obtained in domestic markets and is low in overall cost.

Detailed Description

The key of the utility model lies in: power is provided by rotation of the drive shaft 6.

When the bicycle runs on stairs, the transmission shaft 6 moves rightwards, the right flange 3 is controlled to be attached to the left flange 5, and the rotation of the transmission shaft 6 is synchronous with the bevel gear A7; the transmission shaft 6 rotates 90 degrees to drive the bevel gear A7 to rotate, so that the bevel gears B2 rotate 90 degrees at the same time; at this point, the deforming wheel has been converted to a cross wheel, as shown in FIG. 3.

After the conversion is completed, the transmission shaft 6 moves leftwards to control the right flange 3 to be separated from the left flange 5, and the transmission shaft 6 rotates to transmit power, so that the cross wheel rotates, and the stair climbing action is realized.

When entering the flat ground from the stairs, the transmission shaft 6 moves right again to control the right flange 3 to be attached to the left flange 5; the transmission shaft 6 rotates 90 degrees, so that the conical gear A7 and the circular hammer gear B2 rotate 90 degrees simultaneously, the conversion between the cross wheel and the common wheel is realized, and the driving principle is the same as that of the common wheel.

And, the turning lever 11 is connected with two identical drum brake semi-rings 10, and the speed reducing spring 12 can cooperate with the drum brake semi-rings 10, the drum brake semi-rings 10 and the turning lever 11 to control braking, adjust direction and operate state.

When the vehicle runs on the conventional hard road surface such as a highway, the wheels do not deform, and the running principle is the same as that of the conventional wheels.
