As the further optimization of above-mentioned improvement, can elastomeric element be set, as spring, makes tire adduction normally, thus reduce tire to the impact of wheel rolling as far as possible.
As further improvement, described driving lever can be resilient, if thus tire do not snap onto plane on step and be subject to step side extruding, then pushed adduction.
As further improvement, trundle is set at the head of tire, is then conducive to reducing the resistance and wearing and tearing that cause in tire kiss the earth or stair side process.
Tire is arranged on wheel face by pivot pin, and in order to avoid when vehicle high-speed operates, centnifugal force and impact cause tire overhanging, described pivot pin should through the barycenter of tire.
Use the wheel for climbing building of the present utility model, vehicle does not need to increase extra engine installation can be possessed and climb building ability, and only need increase the parts such as tire and corresponding plectrum, spring on common motive power wheel, the volume therefore increased and cost are also very little.Climb building and normally can not change between motoring condition or make simple conversion.Can be identical with common vehicle when normal flat pavement running.Further, wheeled cart for travelling up or down stairs of the present utility model can be ascended higher than the step of radius of wheel.

Detailed description of the invention
Below in conjunction with drawings and Examples, the wheel for climbing building of the present utility model is described further.
Embodiment 1: the present embodiment be arranged on two-wheeled transport trolley for the wheel of climbing building, described transport trolley has left and right two independent powers wheel, and vehicle body can loading, and both sides, car rear portion jug grasps vehicle for people, is mainly used in delivery article stair activity.In view of seldom running for level road, therefore have employed a kind of simple tire structure.Fig. 2 is its power wheel structural representation.Wheel 2 is arranged on wheel carrier 1, and tire 3 is arranged on the side of wheel 2 by tire rotating shaft 22, has tension spring to connect each tire in addition, makes tire overhanging normally in a free state.Each wheel 2 has 4 tires to be arranged on side symmetrically.When close to step, tire 3 snaps onto the upper plane of step in rotation, and due to the effect of tire limited post 21, tire equivalence becomes the outstanding fulcrum of wheel, and thus with the rotation of wheel, tire support wheel rises, thus reaches the object of climbing building.When tire contact ground, wheel place, the rotation along with wheel is squeezed, by the design of suitable tire rotating shaft position and angle limit, the natural adduction when tire kiss the earth can be made, thus do not affect the operation on level road.Fig. 3 shows in the present embodiment, tire stretches out spacing setting, make tire rotating shaft to the included angle A ng between tire front end line and ground for being less than 90 degree, tire and earth surface position are more smooth cambered surface, thus when being subject to ground extruding, tire 3 inwardly rotates naturally, is conducive to reducing tire wearing and tearing and running resistance.Further, be provided with tire roller 31 in tire front end, thus greatly reduce the friction between tire and ground.Because general stairway step height is 10-20 centimetre, wheel 2 diameter of the present embodiment is about 20-50 centimetre, and preferred wheel 2 diameter is 30 centimetres, and tire length is about 10 centimetres.
