Abstract

The invention relates to a wheel for stair-climbing carts, stair-climbing wheelchairs or obstacle surmounting vehicles, in particular to a multi-universal-wheel frame comprising universal wheels 1, a frame 2, and a pin assembly 3. The frame is a polygonal star frame, available in four types, namely a triangular star frame, a quadrangular star frame, a pentagonal star frame and a hexagonal star frame, respectively corresponding to a three-universal-wheel frame, a four-universal-wheel frame, a five-universal-wheel frame, and a six-universal-wheel frame. The four types of frames are all composed of two necessary parts, namely universal wheels and a polygonal star frame, and accordingly belong to a same invention design. According to a principle, during translational motion, the polygonal star frame never rotates orbitally, the two universal wheels rotate around their axes, and transverse sliding is also allowed, namely universal motion is achieved; during climbing stairs, the universal wheels rotate around their axes and transversely slide to steps first and bear resistance for rotation then, the polygonal star frame rotates orbitally, and the universal wheels rotate around their axes and slide then; during climbing downstairs, two universal wheels land first, the universal wheels rotate around their axes and slide until at least one suspends, and the polygonal star frame then rotates orbitally downstairs.

Referring to Intellectual Property in China net: proprietary term " stair-climbing wheel chair ", number of patent application: CN200910041584.6.
Three, summary of the invention:
1 technical matters solving:
The combination that wheel carrier revolution, omni-directional wheel rotation and omni-directional wheel laterally slide when realizing cat ladder, realizes Omni-mobile, hereby applies for “Duo omnidirectional wheel carrier " patent.This wheel carrier can substitute steering hardware, and when double dynamical, can make upstairs going cart turn radius is zero, saves diff.
2 technical schemes of implementing:
2.1 concrete structures:
Omni-directional wheel on each angle of multi-corner star-shape frame one, is arranged on multi-corner star-shape frame hole by bearing pin assembly, and multi-corner star-shape frame can be single, double row.
Omni-directional wheel is comprised of turning rolls, roller, roller shaft, nut, and omni-directional wheel is divided into two frame perpendicular axis type omni-directional wheels and single frame clino-axis type omni-directional wheel.On each frame of two-wheel frame perpendicular axis type omni-directional wheel, have the roller shaft vertical with turning cylinder, roller is assemblied on roller shaft, and two turning rollss are mutually 45° angle, and two turning rollss and roller form a circle.The turning rolls of single frame clino-axis type omni-directional wheel tilts, and roller is assemblied on turning rolls, and from rotating shaft direction, roller forms a circle.
Wheel carrier (multi-corner star-shape frame) be shape as twist drill centre hole and the omni-directional wheel hole of polygonal star, wheel carrier can single, doublely be arranged.Multi-corner star-shape frame application protection type comprises: triangle starframe, four jiaos of starframes, pentacle frame, hexagram frame.
Omnidirectional's many wheel shapes frame of application protection comprises: omnidirectional's three wheel carriers, four-wheel Jia, omnidirectional of omnidirectional five wheel carriers, omnidirectional's six wheel carriers, they are combined by triangle starframe, four jiaos of starframes, five jiaos of pinion carriers, hexagram frame and omni-directional wheels respectively.
2.2 practical functions:
Wheel carrier can automatic turning when running into step, and wheel carrier can move to any level direction.
3 beneficial effects:
(1) simple in structure, only there are two major parts.
(2) powerful, can substitute steering hardware, when double dynamical, can make upstairs going cart turn radius is zero, and saves diff.
(3) cost economic, omni-directional wheel used is batch manufacturing, and multi-corner star-shape frame is easy to manufacture, therefore overall cost is not high.
