Description
Technical field
The present invention relates to a kind of crawler type that is arranged on the traveling gear on the both sides, chassis instrument that travels that has.
Background technology
Traditionally, a kind of such crawler type instrument of travelling has two dynamic assemblies, dynamic assembly of each traveling gear configuration, and the speed of these traveling geaies can be regulated with being separated from each other, passes through curved path can control the instrument of travelling.Fig. 1 shows the traditional operating structure for described two dynamic assemblies.Two control stalks 1 arrange swingably around common axis 2.Cable core 4 is fixed on by two Bowden cables 5 on the arm 3 of control stalk 1, and these Bowden cables are delivered to the motion of each control stalk 1 on the dynamic assembly of being controlled by control stalk.When the speed of each traveling gear and the control stalk 1 of attaching troops to a unit separately from center position be deflected into ratio the time, the radius of the curved path that is travelled by the instrument of travelling depends on the ratio between the deflection of these control stalks 1 so.Therefore, between the radius of the position of each bar and the curved path that travels, do not exist clear and definite related, and when the crawler type instrument of travelling travels by after the curved path again during straight-line travelling, chaufeur must or see control stalk 1 or touches two control stalks 1 with hand simultaneously, with accurately placed side by side they.That is to say that this does not have a center position---control stalk can be placed in the described center position with the straight line that travels---of clearly fixing is arranged but is used for the needed bar of straight-line travelling position is to be defined with respect to corresponding other control stalk as greatly in bearing circle.This makes the flexible manipulation of the instrument that travels become difficult and effort.
Summary of the invention
Task of the present invention is, proposes a kind of crawler type instrument that travels, and this crawler type instrument that travels makes the operation of simplifying become possibility with the simple and low-cost steering hardware that is configured.
Described task solves in the following manner, namely have be arranged on the both sides, chassis, can be separated from each other in the traveling gear of ground control rate, the control stalk control of the speed of two traveling geaies by can in two degree of freedom, moving.An independent bar is enough, with simultaneously and control independently of each other travel not only speed but also the direction of instrument.
The deflection of control stalk in first degree of freedom should be determined the average velociity of two traveling geaies with suitable manner, and in contrast to this, the deflection in second degree of freedom should be determined the velocity contrast between these traveling geaies.Therefore, in second degree of freedom, can determine center position, velocity contrast vanishing in described center position, and the speed straight-line travelling of instrument to determine by the position of in first degree of freedom, regulating simultaneously that travel.
Specifically, when the handle of control stalk can be in first degree of freedom---by the described degree of freedom control instrument speed of travelling---on the instrument longitudinal direction that travelling and can in second degree of freedom, when the instrument of travelling moves in a lateral direction, so especially draw a kind of for operator's relevance simple and easy steering response, between the reaction of the motion of control stalk and the instrument that travels direct, understandable, that guarantee the instrument that travels---by described degree of freedom control curved path radius---.
The speed regulator of two traveling geaies can be by Bowden cable and control stalk coupling.This especially can transform the existing instrument that travels according to the present invention, and its mode is to substitute two traditional control stalks, as shown in Figure 1 by single control stalk according to the present invention.
In the control stalk degree of freedom at least one, especially second degree of freedom should preferably be swung degree of freedom.There is such possibility then, the axis of oscillation of described degree of freedom namely vertically is set with respect to a mirror plane, two Bowden cables arrange symmetrically about the mutual mirror image in described mirror plane, thereby make motion in second degree of freedom cause the correspondingly opposite displacement of these Bowden cables.
Because when turning driving, velocity contrast between these traveling geaies is significantly less than the velocity amplitude of these traveling geaies usually, so what be fit to is, if when two degree of freedom are swing degree of freedom, so, these Bowden cables have than about the longer throw of lever of the axis of oscillation of second degree of freedom about the axis of oscillation of first degree of freedom.
Can be simply and be implemented in two hunting motion freedom in the degree of freedom at low cost by X conn, control stalk remains on the instrument of travelling by described X conn.Alternately, also can consider to use sphero-joint.
When control stalk is not fixed in the inflection point by chaufeur, retracing spring can be set, with the direction Loading Control bar towards center position.At this, if the center position of second degree of freedom, when decontroling control stalk, the instrument that travels is transformed into straight-line travelling automatically so; If the center position of first degree of freedom or two degree of freedom, when decontroling control stalk, the instrument that travels stops automatically so.
Suitable is, can be provided with for control stalk and control stalk is locked at device in the center position of second degree of freedom in the first degree of freedom deflection.Make in the second degree of freedom deflection such mode of difficulty that becomes by these devices, when speed must be mated, these devices made chaufeur keep the straight-line travelling direction at an easy rate.
Preferably, the instrument of travelling according to the present invention is combination machine.

The specific embodiment
Fig. 2 has schematically shown combination machine 10, and the present invention can use at described combination machine.The chassis of combination machine 10 comprises two crawler type walking mechanisms 11 on the first from left right side, can only see the wherein crawler type walking mechanism in left side in the drawings.These traveling geaies comprise respectively the preceding and back wheel flutter 13 that twined by crawler belt 14 and along the support wheel 15 of the circuit distribution of crawler belt kiss the earth.By the combustion engine coupling of fluid mechanics driving device and combination machine 10, wherein, can by in operator's compartment 12 one common control stalk control respectively by the transmitting ratio of two fluid mechanics drivings device for these two traveling geaies 11.Because combustion engine was with constant rotating speed operation when combination machine 10 was worked in the field, therefore there are direct and clear and definite relevance in the transmitting ratio of two fluid mechanics drivings device and the speed of two traveling geaies 11.
In Fig. 3, with transparent view control stalk and the parts related with it are shown.Extend through hole 17 on the base plate of operator's compartment 12 or in the cover plate on the instrument carrier panel with 16 control stalks that indicate here, and flexible member---is fallen on the ground the bellows 18 that illustrates by partial cut here---edge in hole 17 is connected with the shank of control stalk 16.The upper end of control stalk 16 has handle 19; The lower end is fixed on the base plate of operator's compartment 12 by X conn 20 or in addition on the suitable backing plate.X conn 20 has two axiss of oscillation: axis of oscillation 21, and---it is about the operator's compartment stationkeeping and extend---and second axis of oscillation 22---basically at the longitudinal direction of combination machine 10 it can carry out hunting motion and directed in a lateral direction at combination machine 10 in its center position shown in Figure 3 around first axis of oscillation 21.For control rate and travel direction, control stalk 16 can be simultaneously around two axiss of oscillation 21,22 deflections.Can be provided with retracing spring, be arranged on coil spring 29 in the hole 17 here, not make control stalk 16 be returned in the center position when remaining on control stalk 16 in the inflection point with convenient chaufeur and combination machine is stopped.
On the shank of control stalk 16, two arms 23,24 and X conn 20 have little distance ground fork-shaped to stretch out.On arm 23,24 free end, these ends are fixing by two Bowden cables 26,27 cable core 25.Two arms 23,24 extend symmetrically about a mutual mirror image in mirror plane, axis of oscillation 21 in described mirror plane, extend and described mirror plane vertical with axis of oscillation 22.In the center position shown in Figure 3, the terminal lining 28 of the stationkeeping of two Bowden cables 26,27 sleeve is also about the mutual mirror image symmetry in this plane, and cable core 25 extends between arm 23,24 free end and terminal lining 28 in parallel to each other.
Fig. 4 shows the lateral plan of the steering hardware of Fig. 3, wherein, with solid line control stalk 16 is shown and is in the center position and correspondingly is shown in broken lines control stalk 16 and be in two in the opposite direction from the position of neutral location deflection.Around with respect to vertical axis 22 swings of figure plane the time, two Bowden cables 26,27 cable core 25 move with equal extent at control stalk 16.Here only to see Bowden cable 26; Another is blocked by it.Counter-clockwise swing by control stalk 16 can make cable core 25 retract in the sleeve; Cw hunting motion by control stalk can make these cable cores pull out from sleeve.In the center position of control stalk 16, the pump delivery of two fluid mechanics drivings device is zero, that is to say that combination machine stops.Along with the deflection of control stalk 16 increases, pump delivery increases, and wherein, the throughput direction of pump and the corresponding travel direction that travels that is driven by pump are according to the deflection of control stalk 16 and different.Because, axis of oscillation 22 is vertical in center position at orientation in a lateral direction and the control lever 16 of combination machine 10 basically, so the motion shown in Figure 4 of control stalk 16 is equivalent to the displacement of handle 19 on the longitudinal direction of combination machine 10.Therefore, control combination machine 10 speed in the same direction by the displacement of handle on the instrument longitudinal direction that travels.
Fig. 5 shows at the instrument longitudinal direction that travels, that is to say the same steering hardware that looks up in the side of axis of oscillation 21.Center position is shown and is shown in broken lines inflection point with solid line again.As can be seen, control stalk 16 has caused two Bowden cables 26,27 cable core 25 to move towards opposite sense around axis 21 hunting motions, that is to say, an acceleration in two traveling geaies 11, and another deceleration, and combination machine 10 curved path that travels, its curvature is determined by the velocity contrast between these traveling geaies 11.Suitable is, here attach troops to a unit by this way, namely by handle 19 from center position to left movement, the traveling gear 11 on the left side slows down and the acceleration on the right, and the combination machine 10 curved left curved path that therefore travels.
As comparison diagram 4 and Fig. 5 can clearly be seen that, throw of lever 1
22, 1
21(cable core 25 utilizes these throw of levers and control stalk 16 couplings) is obvious than long about axis of oscillation 21 about axis of oscillation 22.Therefore, the swing that turns over given angle around axis 22 causes the displacement of cable core the last 25 than the hunting motion around axis 21 equal extent.This control rate difference and the turn radius that travels of control delicately thus.
As in Fig. 3, identifying, the yoke portion 31 that X conn 20 comprises that stationkeeping is in the first yoke portion 30 on the car body of combination machine the trend of directed axis of oscillation 21 on the instrument longitudinal direction---this yoke portion determine to travel---and be connected with control stalk 16, these yoke portions interconnect by cross body 32.Fig. 6 shows the transparent view according to the cross body 32 of improved configuration of the present invention.Axis of oscillation 21,22 and axle journals 34,35 that be coupled in yoke portion 30,31 hole that stretch out by matrix 33 by four are determined.Matrix 33 is made up of two semicylinders 36,37, and their axis is correspondingly consistent with axis of oscillation 21 or 22. Semicylinder 36,37 is respectively equipped with recess 38,39 at its periphery, here the form of the groove that extends abreast with the axis with respect to semicylinder.
In two yoke portions 30,31, it---here is leaf spring 43---towards 32 loadings of cross body that stop-motion body 40 or 41 can vertically be directed to and pass through spring movably with respect to the axis of oscillation 21 or 22 by relevant yoke portion 30,31 definition.Fig. 7 illustrates the X conn 20 in the center position that is in two degree of freedom.Two stop- motion bodies 41,42 here snap onto in the recess 38,39 of their semicylinder 36 or 37.Stop-motion body 41 is coupled in the recess 38 of upper semi-circle cylinder 36 and has guaranteed that control stalk 16 occupied dead position under the influence of coil spring 29 is actually following position, and in this position, the speed of combination machine 10 is zero.
When chaufeur promoted handle 16 back and forth, stop-motion body 39 left the recess 38 of upper semi-circle cylinder 36 and moves at its periphery.Because this periphery is columniform about axis 22 here, so leaf spring 43 does not produce the power of the displacement of supporting control stalk 16 or reacts on the power of its displacement; When the center of curvature of periphery is positioned at the another side of axis 21, for example can produce reset force.
Simultaneously, stop-motion body 42 is coupled in the recess 39 of lower semi-circular cylinder 37 and has stoped, when chaufeur moves forwards or backwards handle 16 also by mistake to side deflection.For combination machine 10 is redirect in the curved path, stop-motion body 42 also must be extruded from recess 39 on lower semi-circular cylinder 37.After finishing turning driving, when stop-motion body 42 snapped onto in the recess 39 again, chaufeur can be felt with hand.Chaufeur will be known so, and combination machine is straight-line travelling again, and he does not need to observe the path of passing by for this reason.This make turn to fast and accurately very easy.
