Realize best way of the present invention:

As Fig. 1 and Fig. 2, supporting plate 1 is the curved surface that is slightly less than radius of wheel with the radius of curvature that the thick high tensile steel plate bending of 2mm forms, arc length 25cm, the long 35cm of bus.Rigid hanger 2 and suspension bracket 3 are welded in the two ends of supporting plate 1 respectively admittedly, and a parallelogram breach is respectively stayed at two end places at center bus 7, breach and bus 7 have a certain degree, and are used for installing wheel 4 and wheel 5, form arc pallet 1 is lifted on the great wheel arbor below by rigidity form.Wheel 4 wherein becomes α angle and β angle (aftermentioned) with the wheel plane of wheel 5 respectively with bus 7.Article two, positioning bar 6 is two parallel strings that are fixed on the curved surface side, make of T-steel, apart be the width of wheel, one of effect is the strength and stiffness that increase curved slab.

The combinations thereof body, promptly so-called revolver holder, concave upright when lying against ground, bus 7 is parallel to ground, apart from ground 2cm height.

As Fig. 3 and Fig. 4, lift the thick high tensile steel plate of plate 8 usefulness 2mm and make, be octagon ABCDEFGH.AB and opposite side EF are at a distance of 35 centimetres, and CD and opposite side GH are at a distance of 25 centimetres.The lower surface of plate is equipped with three wheels:

cardan wheel

9,10 and roller bearing wheel 11.The axial length of roller bearing wheel 11 is 20cm, and diameter 5cm only, its surface is made by high coefficient of friction material.Vertical mutually the dividing equally of axis of the line of two cardan wheels and roller bearing wheel.Positioning bar 12 is two long 25cm, and the steel plate bar of wide 4cm is down " eight " font and is welded on CH, the DG line, and one of effect is the strength and stiffness that increase surface plate.When keeping flat ground, plate 8 is apart from ground 6～8cm.So-called right wheel holder that Here it is.

The application and the workflow of said apparatus are: withdrawing from the parking stall to the right with the before driving car is example.Lay the front of two rear wheels about respectively supporting plate 1 and supporting plate 8 being abutted against, and two wheels about noting respectively positioning

bar

6,12 forward being aimed at.Slowly drive about 15 centimetres forward, when the center of two trailing wheel malleations at two supporting plates, parking parking brake trailing wheel.Two wheels can accurately be located in the said process, and positioning

bar

6,12 will play an important role.Slowly reversing then, the action of reversing will be drawn following very important result: it is center of circle turning clockwise translational shifting with the off front wheel of car that car load is taken turns holder with two.Its mechanics principle is: in the reversing process, and pressure, friction force becomes two to two wheel holders relative to static integral body (two rear wheels " no longer rotate " extremely important because of parking brake) here with two incorporated in vehicle wheels respectively with positioning bar 6,12.During the reversing beginning, two front vehicle wheels produce driving static friction force backward simultaneously, but the propulsive effort of off front wheel horse back is by the axial friction counteracting of ground in the face of wheel 11, because these two power are opposite sign but equal magnitude all the time, and in-line, car be can not form retreat or rotary action.The near front wheel then can produce the moment M that makes car load turn right and move.Because according to the structure of wheel holder, the propulsive effort with preceding left wheel is not vertical with the wheel plane of taking turns 11 for wheel 4, wheel 5, takes place so do not have the situation of offsetting kinetic moment M.But having some very important resisting moments, its major cause is: aforementioned α and β have bigger number of degrees error.Therefore α and β angle to be set as far as possible accurately, reduce resisting moment.Determined α and β angle will be only when the wheel plane of wheel 4 grades is vertical with the straight line at the center of front right wheel by car respectively.

Positioning bar

6,12 relative positions with steady wheel holder and wheel play an important role to keeping the minimum drag square.(different vehicles will have different α and β angle)

Aforesaid supporting plate 8 will be far above the purpose of supporting plate 1: 1. the near front wheel and the off hind wheel pressure over the ground that increase car, thereby make the near front wheel can produce bigger kinetic moment M, wheel 11 can produce bigger axial friction (maximum static friction force is directly proportional with pressure), thereby can more effective balance right front wheel back to propulsive effort, more effective stable off front wheel serves as the status and the effect in the center of circle; 2. reduce the off front wheel and the left rear wheel pressure over the ground of car, so reduce that off front wheel can produce back to propulsive effort, thereby status, the center of circle and the effect that can further stablize off front wheel.This The Application of Technology is that the center of circle promotes car load transfer to the right with more effective off front wheel with car in a word.When the tailstock produces the parking stall, loosen parking brake, bottom plate 1 and supporting plate 8 are sailed in reversing, continue reversing and withdraw from the parking stall.

If withdraw from the parking stall left, only need to change one of them action, promptly " parking brake trailing wheel ... slowly reversing " becomes " parking brake trailing wheel ... slowly advance ".Sail the parking stall into to above-mentioned stressed and motion conditions is similar.

The minicar discrepancy parking stall of rear drive is stressed same as described above with motion principle.
