Abstract
The present invention relates to a traffic automobile technique, particularly to an automobile with eight feet. The present invention is mainly characterized in that the wheel positions of the running systems of the existing automobile are provided with eight automobile feet, so the automobile can walk with the eight automobile feet by a coordination mode to replace the running mode of the existing wheel, namely that in four pairs of automobile bridges, each automobile bridge is provided with a supporting arm and a driving arm matched with the automobile feet for driving the automobile feet to swing to and fro. The present invention overcomes the defect that the existing automobiles can not walk without feet, and the present invention is suitable for military affairs, traffic transportation, recreation, etc.
Description
The present invention relates to traffic vehicle technology, particularly a kind of eight-wheel vehicle.Be applicable to military affairs, communications and transportation, travel etc.,
In the running device of existing vehicle such as automobile wheel is arranged all, power driven wheel and travelling.Because apodia is so can not use sufficient walking.See volume " automobile construction " People's Transportation Press of Jilin Industry University automobile teaching and research room version in 1976.
And though four cars foot is arranged in the running device of the bionical walking vehicle that Chinese patent 91227300.3 is proposed, stable inadequately during walking.For example with one the step/minute low-speed running when walking.
The objective of the invention is to overcome the deficiency on the above-mentioned existing vehicle and provide eight cars foot is arranged in a kind of running device, reposefully the eight-wheel vehicle that advances of walking.
Realize that the object of the invention method is provided by following principle, measure, accompanying drawing, CONSTRUCTED SPECIFICATION and service condition.
Principle of the present invention and measure are: be installed in the running device of existing full drive-type cross-country car with eight car foots, replace the driving functions of the wheel of existing automobile with the walking-function of car foot.
In the structure of full drive-type automobile, the vehicle bridge of running device one total fourth officer drive axle, cooperate with eight car foots, the power that makes car is by dynamical system, transmission system passes in the driver train of car foot, is driven and the realization walking by the rocker-arm actuating arm, and promptly the front and back four-footed lands earlier, then eight foots land, change into then other four-footed simultaneously and land, and transfer eight foots again to and all land.
The driver train of car foot is that two ends are connected with " 7 " font hold-down arm on the vehicle bridge, actuating arm connects semiaxis or outer semiaxis.Cooperate with car foot simultaneously by hold-down arm and actuating arm with rectangular guideway hole and axis hole.The car foot is a straight column type.
Car on the steering drive axle can turn to completely, the drum brake mechanism in the brake system is installed between actuating arm and the hold-down arm.But the tie rod arm of steering system should change rectangular arm into.
Other structure of car is identical with the corresponding construction of existing all wheel drive automobile.See volume " automobile construction " People's Transportation Press of Jilin Industry University automobile teaching and research room version in 1976.
But each drive axle is the penetration type drive axle, and indifferential.
The invention has the advantages that existing automobile can replace the wheel in the running device, and have stationarity with the walking of eight car foots, is specially adapted to military affairs etc.

4Every secondary vehicle bridge two ends vertically connect the hold-down arm 9 of forward sight for " 7 " font respectively.The upper end of arm vertically is fixed with a circular shaft shape support shank 3.Promptly the steering swivel shell 17 at first, fourth vehicle bridge two ends axle journal 18 is arranged, the tabular hold-down arm 9 of the prismatic that is being permanently connected, the ends that the diameter of its outer semiaxis 23 is bigger than semiaxis 14, vertical fixing ground in outer end connects the tabular actuating arm 22 of prismatic, this arm vertically connect a circular shaft handle 2; The be permanently connected outer end of hold-down arm 9, its semiaxis 24 of axle journal 29, the two ends of the mat woven of fine bamboo strips two, three vehicle bridge axle housings 25 connects the diameter shaft adapter 28 bigger than semiaxis, and the end that shaft adapter vertically connects actuating arm 27, arm more vertically connects circular shaft handle 2.Support shank 3 can be vertical with horizon to lateral plan with the C of the line of semiaxis 24 or outer semiaxis 23 during installation, also can be with the horizon out of plumb, promptly be partial to the front side or the rear side of horizontal vertical line.The length of each root car foot is all identical with structure.
Every car foot 20 is the vertical cyclindrical shape foot, and upper semisection has an oblateness or rectangular guide rail hole 1, and the below in hole has a circular shaft hole 19, the rotating connection done with circular shaft handle 2 in hole 19, and the outer end of handle is by 21 lockings of a baffle ring; The inside and outside both sides that then are inserted with support shank 3, handle in the guide rail hole are fixed with two baffle rings 6.
Rotate along with power makes semiaxis 14,24, actuating arm 22,27 just rotates, and its circular shaft handle 2 will promote car foot 20 and do the reciprocating type swing in front and back abreast.
But the rotating speed that guarantees the semiaxis 14,24 of each vehicle bridge equates; And each actuating arm d

8 Circular shaft handle 2 be oriented identical with bridge, first, fourth vehicle bridge is also identical or second and third vehicle bridge is also identical, and first, fourth vehicle bridge is opposite with second and third vehicle bridge.For example, the circular shaft handle 2 on first, fourth vehicle bridge is all towards the place ahead, synchronously the circular shaft handle 2 of the mat woven of fine bamboo strips two, three vehicle bridge all towards after.
The structure of brake system is identical with the corresponding construction of existing automobile, and drum brake mechanism 7 is arranged, and is installed between actuating arm 22,27 and the hold-down arm 9.For example the brake wheel of drg is fixed on the actuating arm 22, and brake shoe brake cheek and rest pin are fixed on the hold-down arm 9.
The penetration type drive axle of above-mentioned indication should be that the penetration type twin-stage main gear device with indifferential, the differential lock that is about in the existing corresponding main gear device, make it stiff, make same drive axle about two semiaxis 46,50 can only do synchronous rotation.For example, the axle side gear in the diff is fastened to each other, or left and right sides semiaxis connects into an axle.
Another embodiment of each above-mentioned driver is a penetration type worm and gear main gear device.See Fig. 8, promptly the spline of the left and right sides semiaxis 4650 in each drive axle is being overlapped regularly by a spline housing 47, and this cover is overlapping regularly.This cover worm gear 49 that is permanently connected, this is taken turns and is fixed in worm screw 51 engagements that run through on the axle 52.Run through axle 52 front and back, and connect its adjacent transmission shaft by universal-joint through box-type active driver shell.The transmitting ratio of each driver is all identical with the rotating speed of semiaxis.
The lower end of every car foot be pin all, can be for spherical, or structure by foot joint 33, front and back spring 44, sole joint 31, bearing pin 34, go up sole 36, lower footplate 38 soles supporting 42A, bolt 37 and form.Foot joint 33 be forked, has axis hole 32, side respectively has a supporting to push up 30 before and after it; This joint top connects car foot 20 or G
