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 band auxiliary fins wheel that vehicle is maked an inspection tour in the survey of deep space such as a kind of moonscape.
Background technology:
The many employings of 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 " such as U.S.'s emission;
B) be with elastomeric screen cloth wheel; The lunar rover vehicle LRV that adopts such 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 larger, 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 quality light, and its distortion can increase the wheel ground contact area under load, the soft soil trafficability that is conducive to wheel, but this version is larger in the hardstand distortion, and soil is softer, distortion diminishes on the contrary, and when the hard thing such as stone was arranged, the wheel screen cloth can produce destruction, was fit to vehicle weight larger, 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.
Process is to prior art literature search discovery, and China Patent Publication No. is CN 101524841A, and 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 form forms, and when the wheel stand under load, wheel up and down two suite handle slide block mechanisms is synchronized with the movement to guarantee that wheel is in ellipticalness.But this version movable part is many, and complex structure has brought security risk.
In addition, China Patent Publication No. 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, by the relative motion between bindiny mechanism and wheel hub, realize the flexible of the variable and structure of wheel diameter.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:

In another preferred a kind of lunar roving vehicle wheel technical scheme with auxiliary fins provided by the invention, described auxiliary fins coupling end is hinged on described tire side.
In the more preferred a kind of lunar roving vehicle wheel technical scheme with auxiliary fins provided by the invention, described wheel hub installation shaft axial sides is provided with eccentric wheel, described eccentric wheel and described wheel hub installation shaft concentric, the described eccentric center of circle is higher than the axle center of described tire installation shaft, described eccentric wheel is equipped with the eccentric wheel wheel disc by eccentric shaft bearing, described eccentric wheel wheel disc is provided with connecting rod, and described connecting rod is connected with auxiliary fins on the described tire.
In another preferred a kind of lunar roving vehicle wheel technical scheme with auxiliary fins provided by the invention, eccentric wheel wheel disc on the same side of described tire is provided with the mounting hole corresponding with the described auxiliary fins number of homonymy and position, the installation direction of described connecting rod is consistent with the radius directions of rays of described tire, described connecting rod one end is hinged in the described mounting hole, and the other end is hinged on the position beyond the coupling end on the described auxiliary fins.
In another preferred a kind of lunar roving vehicle wheel technical scheme with auxiliary fins provided by the invention, the auxiliary fins on the described tire side is not less than four, and distributes symmetrically as the center of circle take described wheel hub installation shaft axle center.
In another preferred a kind of lunar roving vehicle wheel technical scheme with auxiliary fins provided by the invention, the integral body behind described each auxiliary fins and the rod hinge connection with the radius ray of described tire as axis of symmetry, left-right symmetric.
Because the beneficial effect that has adopted technique scheme, the present invention to obtain is:
1, the ground contact area of increase wheel is the important channel of improving wheel hag carrying capacity, different from other inventions in the past, the present invention from increase hag by the time wheel width so that the ground contact area of wheel when greatly increasing, has avoided changing the complexity of wheel diameter.
2, the present invention increases the center of gravity of also avoiding improving vehicle at Width, has guaranteed the riding stability of vehicle.
3, the present invention just just produces the distortion on the wheel Width in the wheel ground area, and on the top with respect to the ground area, the variation of wheel on Width recovers, and avoided the interference in wheel and compartment.
