Abstract
The invention relates to the field of lunar vehicles, in particular to a wheel with auxiliary fins for moonscape exploration tour vehicles and other deep space exploration tour vehicles. The wheel comprises a hub and a tire, wherein auxiliary fins are arranged on at least one side surface of the tire, one ends of the auxiliary fins are connecting ends connected to the side surface of the tire, ends of the auxiliary fins, opposite to the connecting ends, are opening ends, the direction of the connecting ends of the auxiliary fins to the opening ends of the auxiliary fins is consistent to the radius ray direction of the tire, the auxiliary fins are shaped as an arc being gradually away from the side surface of the tire from the connecting ends to the opening ends, and a vertical height from the lowest point of the auxiliary fins to the extended axis line of the tire is not more than the rolling radius of the tire. When the wheel is driven to run on the soft ground, because thrust of soil enables the auxiliary fins to be deformed or the auxiliary fins are driven by an eccentric wheel to swing upwards, a contact part of the whole wheel and the ground is widened, the fins share partial wheel loads and prevent the wheel from further sinking, thus the soft ground passing capacity of the wheel is improved.
Description
Technical field:
The present invention relates to lunar rover vehicle field, relate in particular to the auxiliary fin wheel of band that vehicle is maked an inspection tour in survey of deep space such as a kind of moonscape.
Background technology:
The many employings of the present interspace detection vehicle and the lunar rover vehicle are wheeled to be main configuration.Wheel is one of the most key parts of interspace detection vehicle and lunar rover vehicle running gear, and it is bearing the critical function that supports that car load is unlikely to sink and rotatablely moving of wheel driver changed into forward vehicle motion.Count the interspace detection vehicle of successful launch one by one, below two kinds of keystone configuration forms that version is interspace detection vehicle.
A) metal rigidity wheel; Marsokhod " Suo Jiena " and " Opportunity Rover " as U.S.'s emission;
B) be with elastomeric screen cloth wheel; The lunar rover vehicle LRV that is adopted as the U.S. " granny sieve " plan;
Above described two kinds of versions merits and faults is respectively arranged.The metal rigidity wheel, simple in structure, reliable operation, resistance to motion is little on the hard pavement, but structural weight is bigger, can not take into account the rideability on the weak soil face, easily produces depression, is adapted on the moderate middle-size and small-size vehicle of complete vehicle weight.Be with elastomeric screen cloth wheel light weight, and its distortion can increase the wheel ground contact area under loading, the soil trafficability energy that helps wheel, but that this version is out of shape on hardstand is bigger, and soil is soft more, distortion diminishes on the contrary, and when hard thing such as stone was arranged, the wheel screen cloth can produce destruction, and it is bigger to be fit to vehicle weight, moving velocity is very fast, and the vehicle of certain shock attenuation needs is arranged.
Therefore, have a lot of engineering staff to design the wheel of taking into account hard pavement and soft road traveling, their thinking is to realize by the actual theoretical running radius of tire or the effective rolling radius that change wheel mostly.
Through the prior art literature search is found that the Chinese patent publication number is CN 101524841A, open day be: on September 9th, 2009, patent name is: a kind of flexible ellipse-like wheel of detection robot.1 kind of flexible ellipse-like wheel of detection robot that this patent is announced, this wheel has flexible rim, the slider-crank mechanism that strut bar and slide bar are formed is formed, and when the wheel stand under load, two set of bell cranks slide block mechanisms are synchronized with the movement and guarantee that wheel is in ellipticalness about the wheel.But this version movable part is many, and complex structure has brought security risk.
In addition, the Chinese patent publication number is CN 1686723A, and open day be: on October 26th, 2005, patent name is: intelligent variable diameter semi walking wheel.This Invention Announce a kind of intelligent variable diameter semi walking wheel, by drive motor, open motor, two-way harmonic speed reducer, bindiny mechanism etc. and form,, realize the flexible of the variable and structure of wheel diameter by the relative motion between bindiny mechanism and wheel hub.Thereby realize the variation of wheel on diameter.But this version complex structure, and after diameter became greatly, it is discontinuous that tyre surface becomes, and polygon effect strengthens, the riding comfort variation of wheel.
Summary of the invention:
