(front-wheel supporting device)
Fig. 4 is the exploded perspective view of the front-wheel supporting device 30L of supporting left side front-wheel 22L.Based on Fig. 1 to Fig. 4 front-wheel supporting device 30L is described in detail.Because the front-wheel supporting device 30R of off-front wheel 22R and front-wheel supporting device 30L are to be the structure that reference mirror is faced title with the Y-Z plane, the Therefore, omited is to the explanation of front-wheel supporting device 30R.In addition, the corresponding part of each component part for front-wheel supporting device front-wheel supporting device 30L 30R and that the following describes replaces to R by the label L that each component part marked with front-wheel supporting device 30L and describes.Front-wheel supporting device 30L is located on the left surface of car body 90, and front-wheel supporting device 30R is located on the right flank.
Front-wheel supporting device 30L has: turn to rotary body 32L, via rotating shaft 31L supporting front-wheel 22L, make it rotatable; Wheel support body 33L, supporting turns to rotary body 32L, and making it can be that rotate at the center with the direction with rotating shaft 31L quadrature; The 35L of rotating support portion, 36L carry out axle supporting by bolster 34L to wheel support body 33L in the bottom, left side of car body 90; Distance piece 37L remains on wheel support body 33L along on the assigned position of bolster 34L; Sprung parts 38L is as relaxing from the buffer body of front-wheel 22L biography to the vibrations of car body 90; Suspension maintaining part 39L keeps this sprung parts 38L in car body 90 sides.
Above-mentioned front-wheel 22L can be with respect to the rotating shaft 31L rotation that is positioned at its center, and this rotating shaft 31L remains on and turns on the rotary body 32L.
Turn to rotary body 32L for roughly cylindric, 31L keeps to rotating shaft, makes its place, centre position and this center line C direction quadrature on the center line C of this cylindrical shape direction (above-below direction among Fig. 4).In addition, at the both ends that turn on the center line C direction of rotary body 32L, be formed with respectively along the outstanding circular projection 32La (projection of downside is not shown) of this center line C direction, turn to rotary body 32L to be bearing on the wheel support body 33L via these circular projection 32La.And,, can be that rotate with respect to wheel support body 33L at the center with center line C direction so turn to rotary body 32 because each projection 32La is circular.
And then, on the upper end that turns to rotary body 32L, have the driven arm 32Lb that stretches out along the radial direction of its cylindrical shape.At the leading section of this driven arm 32Lb, be set with the engaging protrusion 32Lc of pole shape abreast with center line C direction.When turning to, this engaging protrusion 32Lc is pushed to any direction along X-axis by the steering arm 69 of steering mechanism 60 described later.Thus, turn to rotary body 32L to rotate with respect to wheel support body 33L, the direction of advance of front-wheel 22L changes, thereby carries out turning to of moving toy 100.Again, steering arm 69 forms, simultaneously, equidirectional ground and with identical displacement to about turn to rotary body 32L, 32R to carry out steering operation.
Below, at first the steering arm 69 to steering mechanism 60 describes.Steering arm 69 has: the 69a of slip plane portion is bearing in the gathering sill of being located on the car body 90 (not shown), along the X-direction action that reciprocatingly moves; Initiatively arm 69Lb, 69Rb, the both ends from the length direction of the 69a of slip plane portion are stretched out along its length and are crooked and form on intermediate vertical ground respectively; Annulus 69Lc, 69Rc are located at each initiatively on the leading section of arm 69Lb, 69Rb and have a slotted hole.
It is rectangular tabular that the above-mentioned slip plane 69a of portion is, and is bearing in the not shown gathering sill of car body 90, can move in that the parallel plane state of its platen surface and X-Z lower edge X-direction is slided.
In addition, on the 69a of slip plane portion, be equipped with slotted hole, in the lower lip portion of slotted hole, be formed with tooth bar 69d along its length along its length direction in the central authorities of platen surface.This tooth bar 69d and pinion 64 link, when turning to, motor torque is converted to the locomotivity of straight line, steering arm 69 is moved along any direction of X-axis, and described pinion 64 drives rotation by turning to d.c. motor 13 of steering mechanism 60 via clutch mechanism 63.
Each initiatively arm 69Lb, 69Rb extend to the direction that length is prolonged from the both ends of the 69a of slip plane portion respectively and be provided with, on intermediate vertical ground to the equidirectional bending.Described bending direction refers to the vertical direction of platen surface with the 69a of slip plane portion.That is, at the 69a of slip plane portion of steering arm 69 with when the state support on X-Z plane is on car body 90, each initiatively the leading section of arm 69Lb, 69Rb become state along Y direction.
Annulus 69Lc, 69Rc are formed with slotted hole along the leading section of active arm 69Lb, 69Rb.That is, with when the state support on X-Z plane is on car body 90, the slotted hole of each annulus 69Lc, 69Rc also becomes the state along Y direction at the 69a of slip plane portion of steering arm 69.In the slotted hole of described each annulus 69Lc, 69Rc, insert engaging protrusion 32Lc, the 32Rc that respectively turns to rotary body 32L, 32R respectively.Each engaging protrusion 32Lc, 32Rc can tilt along X-direction (aftermentioned), so the short-axis direction width of the slotted hole of each annulus 69Lc, 69Rc is set greatlyyer than the diameter of engaging protrusion 32Lc, 32Rc.In addition, each front- wheel 22L, 22R and turn to rotary body 32L, 32R to regulate (aftermentioned) along Y direction to its configuration with wheel support body 33L, 33R, correspondingly, the length (with reference to Fig. 3) of the long axis direction length setting of the slotted hole of each annulus 69Lc, 69Rc for the position adjustment range of Y direction is included.
Fig. 2 shows the state that utilizes after steering arm 69 turns to.Any direction to X-direction moves steering arm 69 with d.c. motor 13 by turning to, via each initiatively arm 69Lb, 69Rb and each driven arm 32Lb, 32Rb and make and turn to rotary body 32L, 32R to rotate, can carry out steering operation to each front- wheel 22L, 22R to equidirectional.For example, if steering arm 69 moves to the right, then each front- wheel 22L, 22R turn to the left, if steering arm 69 moves to the left, then each front- wheel 22L, 22R turn to the right.
Again, on the position that is positioned at car body inside of steering arm 69, be provided with simultaneously each front- wheel 22L, 22R are got back to towards the back-moving spring of the straight ahead position of straight ahead direction and the adjustment knob of the straight ahead position that will get back to being adjusted by back-moving spring (not shown).Thus, removing, can get back to the straight-line travelling state automatically to turning to when controlling with turning to of d.c. motor 13.
Below, 33L describes to the wheel support body.Wheel support body 33L is supporting and is turning to rotary body 32L, and making it can center line C direction be that rotate at the center.Wheel support body 33L form respectively with the C direction that turns to rotary body 32L on opposed top board 33La in both ends and base plate 33Lb and with the rectangular backplate 33Lc that top board 33La and base plate 33Lb link up, be roughly コ word shape on the whole.That is, top board 33La and base plate 33Lb are perpendicular to backplate 33Lc, and both extend towards equidirectional.On top board 33La and base plate 33Lb, be formed with respectively and accept the receiving hole (not shown) of being located at the projection 32La on the both ends that turn to rotary body 32L, thus, wheel support body 33L rotatably support and is turned to rotary body 32L.
In addition, on plate 33Lc overleaf and the face opposite side with base plate 33Lb of top board 33La, in the length direction centre position, along parallel with its platen surface and be equipped with connecting hole 33Ld with the direction of length direction quadrature, bolster 34L inserts logical this connecting hole 33Ld.That is, become following state: wheel support body 33L, to turn to rotary body 32L and front-wheel 22L can be the center to insert the bolster 34L that leads in this connecting hole 33Ld, rotates with respect to car body 90.
The both ends of bolster 34L remain on two 35L of rotating support portion, the 36L, and the described rotating support 35L of portion, 36L arrange the ground fixed equipment in the left surface bottom of car body 90 with the interval of regulation along Y direction.Therefore, wheel support body 33L can Y direction be that rotate with respect to car body 90 at the center by the bolster 34L supporting along the Y direction configuration.
Here, the interval of two 35L of rotating support portion, 36L is set for bigger than the Y direction width of wheel support body 33L, the distance piece 37L of plug-in mounting tubular in additional space.
Fig. 1 is the state that distance piece 37L is configured in the front side of wheel support body 33L, and Fig. 3 is the state that distance piece 37L is configured in the rear side of wheel support body 33L.
Bolster 34L performance makes the effect of the guide that wheel support body 33L moves along Y direction, makes that the position on the Y direction of this wheel support body 33L can be adjusted.
And, distance piece 37L by optionally being configured in wheel support body 33L the front side and the either side in the rear side, and performance remains on wheel support body 33L the effect of the locational maintaining body of adjustment on the Y direction.That is, can along Y direction the position of wheel support body 33L be adjusted in the scope between the 35L of rotating support portion, 36L by changing the configuration of distance piece 37L.
Like this, even make in that the multiple car body lid adopted various designs is installed above car body 90 under the situation that wheelbase changes, also can come suitable adjustment is carried out in the configuration of front- wheel 22L, 22R by changing each wheel support body 33L, the configuration of 33R on Y direction.
For distance piece 37L, not only can change its configuration, can also prepare the different multiple distance piece of thickness, be used for the front and back of wheel support body 33L, 33R and combine, perhaps, adjust wheel support body 33L, 33R and front-wheel 22L, the 22R position on Y direction at the thin distance piece of each overlapping multi-disc of the front and back of wheel support body 33L, 33R.
In addition, in the above description, around around the connecting hole 33Ld of wheel support body 33L and the hole of distance piece 37L all is continuous, but also the local excision around the hole can be formed cross section C word shape, but also can form these wheel support body 33L and distance piece 37L with having flexible material.By such design, can be pressed into by notch on the bolster 34L that is installed on the 35L of rotating support portion, the 36L the C word shape, wheel support body 33L and distance piece 37L easily are installed.
In addition, on the upper surface of the top board 33La of wheel support body 33L, one is upright abreast is provided with opposed plate 33Le with the platen surface of backplate 33Lc.This opposed plate 33Le by the sprung parts 38L on the left surface that is supported on car body 90 to having given elastic force away from the direction of car body 90, on the opposed faces of car body 90 sides, be formed with and the movable chimeric circular depressions 33Lf of hemispherical jut 38Lc that is located on the sprung parts 38L.
Fig. 5 is the front view of moving toy 100, and Fig. 6 and Fig. 7 are the major part vertical views of sprung parts 38L.
As shown in Figure 5, when each front- wheel 22L, 22R difference ground connection, each front- wheel 22L, 22R are respectively on being positioned at than bolster 34L, 34R position more in the outer part on the width (X-direction) of car body 90, so under the deadweight effect of moving toy 100, wheel support body 33L, 33R are that middle mind-set makes its top rotate near the direction of the side of car body 90 with bolster 34L, 34R.
Thus, each front- wheel 22L, 22R and wheel support body 33L, 33R are the state that Eight characters shape tilts during from top view mutually, and the opposed plate 33Le, the 33Re that are located at the upside of wheel support body 33L, 33R move to the direction near the side of car body 90.But, owing on the side of car body 90, be provided with to the sprung parts 38L, the 38R that produce repulsive force away from the direction of this side, so wheel support body 33L, 33R are pushed open by the elastic force of sprung parts 38L, 38R via opposed plate 33Le, 33Re.Thus, left and right sides front- wheel 22L, 22R are keeping and are being the state that Eight characters shape tilts mutually, relax the vibrations that each front- wheel 22L, 22R bear from ground by sprung parts 38L, 38R, thereby can obtain the buffering effect to car body 90.
And, owing to keeping the heeling condition that downside broadens as front-wheel 22L, the 22R of deflecting roller, so do not having can to keep the steering state of straight ahead under the state of external force action (not carrying out the state of steering operation) by steering mechanism 60.
In addition, as previously mentioned, wheel support body 33L, 33R can be with respect to car body 90 in the enterprising line position adjustment of fore-and-aft direction.Therefore, for sprung parts 38L, 38R, also must can be with respect to car body 90 in the enterprising line position adjustment of fore-and-aft direction.Therefore, as Fig. 5 and shown in Figure 7, suspension maintaining part 39L (39R too) is supporting the base portion of the strip of sprung parts 38L, and it can be slided along Y direction.Thus, can be with respect to the recess 33Lf that on the opposed plate 33Le of the wheel support body 33L that has carried out mobile adjusting on the Y direction, is provided with, on Y direction, sprung parts 38L is carried out same mobile adjusting, thereby its jut 38Lc is entrenched among the recess 33Lf.Therefore, even under the situation that the front and back position that has carried out front- wheel 22L, 22R is regulated, also can keep certain buffering effect.
As mentioned above, in each front- wheel supporting device 30L, 30R, with opposed plate 33Le, 33Re on the top of being located at wheel support body 33L, 33R opposed to each other, dispose sprung parts 38L, 38R at the side of car body 90.Therefore, be that the center obtains front-wheel 22L, the 22R of axle supporting and wheel support body 33L, 33R and is being under the state that Eight characters shape that downside broadens tilts with the Y direction, given flexible repulsive force by sprung parts 38L, 38R, thus can be with respect to of vibrations and the impact of car body 90 bufferings according to the pavement state generation.
And, in each front- wheel supporting device 30L, 30R, by bolster 34L, 34R wheel support body 33L, 33R are carried out the axle supporting and it can be slided along this bolster 34L, 34R, utilize distance piece 37L, 37R to determine its position, so, different with the formation that makes the car body integral telescopic, the adjustment of wheelbase is carried out in the adjustment that can only constitute by slight part.Therefore, can realize the formation adjusted summary, adjust the facilitation and rapidization of operation.
And then, wheel support body 33L, 33R move the formation of regulating at fore-and-aft direction discretely from car body, and be mainly to front- wheel 22L, 22R and the parts that turn to rotary body 32L, 32R to support, so realize miniaturization easily, when carrying out the mobile adjusting of this wheel support body 33L, 33R, the configuration and the irrealizable problem of function of the various formations in the car body needn't be worry can caused being accommodated in as in the past, the adjusting of wheelbase can be carried out with easy formation.
And, because wheel support body 33L, 33R realize the miniaturization lightweight easily,, thereby can keep good transport condition so car body 90 and wheel support body 33L, 33R are difficult for the strain that generation causes because of undercapacity.
And then, even since the steering arm 69 of steering mechanism 60 have as the annulus 69Lc, the 69Rc that have slotted hole under the situation that the front and back position that turns to rotary body 32L, 32R has taken place to change also can be on left and right directions the structure of transferring power, so can not hinder adjusting, stable the turning to of the front and back position of front- wheel 22L, 22R.
And, because sprung parts 38L, 38R can carry out front and back position to be bearing on suspension maintaining part 39L, the 39R with regulating, even so taken place under the situation of variation at the front and back position of wheel support body 33L, 33R, also can be to wheel support body 33L, 33R to giving elastic force away from the direction of car body 90, thereby, can obtain stable buffering effect no matter whether front- wheel 22L, 22R have carried out the front and back position adjusting.
And then even carry out the mobile adjustment of front- wheel 22L, 22R, sprung parts 38L, 38R also needn't carry out miscellaneous refitting operation, only can easily handle by slide, thereby can realize simple and easy rapidization of operation.
(variation of front-wheel supporting device)
In addition, steering arm 69 is to link by annulus 69Lc, 69Rc and engaging protrusion 32Lc, the 32Rc with slotted hole with turning to the engaging position of rotary body 32L, 32R, but relative Y direction moves and the mobile interlock of X-direction is carried out as long as allow producing each other, then can be any type of structure.For example, the projection of slotted hole and pole shape can be arranged on opposition side mutually, can also adopt groove to replace slotted hole.In addition, also the slide unit that the bearing of trend along master arm or slave arm can be moved is arranged on some in two arms, and with another arm and this slide unit can being that the mode that rotate at the center links up with the Z-direction.
In addition, front-wheel supporting device 30L, 30R are not limited to aforementioned formation, so long as can make front-wheel 22L, 22R turn to required rotation and can move adjusting on Y direction, then can be any type of formations.For example, the 35L of rotating support portion, 36L can be arranged to and on Y direction, move, to make wheel support body 33L to move along Y direction with respect to car body 90, also can utilize the sag and swell of lug boss or embedded hole and so on that the 35L of rotating support portion, 36L can be loaded and unloaded and by a plurality of recesses being set or protuberance carries out the position adjustment of the 35L of rotating support portion, 36L in vehicle body side one side along Y direction with respect to car body 90 with bolster 34L.Perhaps, can adopt following formation: on wheel support body 33L, fixedly install plural at least C shape ring coaxially, the internal diameter big bolster 34L of diameter than C shape ring is set on the 35L of rotating support portion, 36L, in its length direction setting of the outer peripheral face upper edge of this bolster 34L in order to a plurality of circumferential grooves of C shape ring rotatably to be installed.In this case, by selecting a plurality of circumferential grooves and utilizing C shape ring that wheel support body 33 is installed, can on Y direction, carry out the position adjustment to this wheel support body 33.
Front-wheel supporting device 30R also is same.
In addition, can be by suspension maintaining part 39L, 39R on Y direction sprung parts 38L, the 38R to front- wheel supporting device 30L, 30R move adjusting, even but the fore-and-aft direction position of front- wheel 22L, 22R is regulated so long as get final product no matter its change in location how, all has the formation of giving the effect of elastic buffer to front- wheel 22L, 22R.
For example, also sprung parts can be made along the strip elastomer of Y direction fixed equipment on car body 90.
Perhaps, also can arrange a plurality of sprung parts of ground fixed equipment in car body 90 upper edge Y directions.
Perhaps, also can on opposed plate 33Le, the 33Re of each wheel support body 33L, 33R, be provided with and the sprung parts side butt of car body 90, that constitute by elastomer.
In these cases, carried out needn't carrying out the position adjustments operation of sprung parts after the front and back position adjusting of front- wheel 22L, 22R, wheel support body 33L, 33R can give elastic force by sprung parts, keep the buffering effect with respect to front-wheel 22L, 22R.And, in these cases, suspension maintaining part 39L, 39R can be set.
