Planetary multi-wheel carrier stair climbing vehicle

Abstract

The invention discloses a planetary multi-wheel carrier stair climbing vehicle. The revolution of wheel carriers and the rotation of small wheels can be automatically switched, so that the vehicle can stably and quickly climb stairs. Core contents are that driving wheels are required to be planetary multi-wheel carriers, non-driving wheels are required to be multi-wheel carriers, and the driving wheels and the non-driving wheels have the same point number, wherein a small wheel is arranged at each point of each multi-wheel carrier which serves as the wheel; a planetary wheel system is additionally arranged on each planetary multi-wheel carrier; the small wheels comprise one-way wheels and omnidirectional wheels. Each multi-wheel carrier of the planetary multi-wheel carrier stair climbing vehicle comprises three wheels, four wheels, five wheels or six wheels. A dour-wheel dual-power four-driven six-wheel carrier stair climbing vehicle is shown in a drawing, wherein small bevel gears are driven through a differential spider by two motors, large bevel gears are driven by the small bevel gears, and are matched with chain wheels, and four wheels are driven by the chain wheels respectively. According to stair climbing principles, 1, when the vehicle runs on a level road, planetary wheels and the small wheels rotate; 2, when the vehicle climbs the stairs, the small wheels rotate to get close to a step, and then the multi-wheel carriers revolve; 3, when the vehicle goes downstairs, the small wheels rotate until one small wheel is suspended, the wheel carriers revolve, and after the suspended small wheel is landed, the wheel carriers continue revolving.

Description

1. Technical field [0001] The "planetary multi-wheel frame ladder climbing vehicle" of the present invention can climb stairs, steps and certain obstacles. The "planetary multi-wheel frame climbing vehicle" is equipped with a "planetary multi-wheel frame", which can realize smooth movements of horizontal walking, climbing and descending stairs, and has strong adaptability to stairs. 2. Background technology: [0002] 1 The technical features of the "planetary multi-wheel frame climbing vehicle" of the present invention: [0003] Summary of features of the invention: [0004] Feature A: The small wheel, the polygonal star frame and the pin shaft assembly form a "multi-wheel frame". Wherein, steamboat comprises one-way wheel and omnidirectional wheel. [0005] A 1 : one-way wheel, polygonal star frame and bearing pin assembly form many one-way wheel frames. [0006] A 2 : Omnidirectional wheels, polygonal star frame and bearing pin assembly form many omnidirectional whee...
