The preceding chassis 11 that unitor 60 is installed serves as that axle is linked to chassis linkage frame 18 freely to rotate by unitor 60 with center pin 61.Therefore, as shown in figure 19, preceding chassis 11 can serve as the rotational of axle around vertical direction with center pin 61 with respect to chassis link span 18, moves on single track R simultaneously.As shown in figure 20, preceding chassis 11 can serve as the rotational of axle around horizontal direction with center pin 61 with respect to chassis linkage frame 18, moves on single track R simultaneously.

The preceding chassis 11 that unitor 60 is installed serves as that an axle freedom rollably is linked to chassis linkage frame 18 with the axis of pitch 80 of its unitor 60.That is to say, in wheel tractor, the unitor 60 that the pitching that makes trailer do to rock back and forth with respect to tractor truck is moved is positioned in two car-type moving vehicles 100 of present embodiment laterally, thus, and the scroll actions that preceding chassis 11 rocks from side to side with respect to chassis linkage frame 18 works.

Therefore, preceding chassis 11 serves as an axle left-right rotation with respect to chassis linkage frame 18 with axis of pitch 80 by unitor 60, corresponding to this rotation, the front end of chassis linkage frame 18 carries out small freely shaking by unitor 60 on left and right directions, therefore, can when curve moves, absorb reversing of chassis and chassis linkage frame 18, thereby can reduce the moving load of the distortion of single track R or each

chassis

11,12 that inclination causes.

Two car-type moving vehicles 100 of present embodiment have said structure, and therefore, for example, along under the situation that moves on the single track R that up and down lay on ups and downs ground, front and

back chassis

11,12 moves with wheel 47 at two chassis moving vehicles 100.

As shown in figure 19, have under the ups and downs situation at single track R, front and

back chassis

11,12 becomes front and back along with the fluctuating of single track R and distinguishes the bevelled state, particularly be positioned at when being marginal position when AM/

BAM car

11,12 with the lowest point that rises and falls, unitor 60 and center pin 61 by preceding chassis 11 also pass through afterwards chassis linkage frame pivotal axis 28a, the 28b of chassis 12, and front and

back chassis

11,12 shakes with the state that tilts forward and back and moves on single track R.

As shown in figure 20, when single track R overlooks under the sweeping situation, preceding chassis 11 horizontally rotates by S. A. main body 66, back chassis 12 is by center pin 61 and unitor 60, before and after

chassis

As shown in figure 19, under the bevelled situation, preceding chassis 11 can and move forward and backward with respect to chassis linkage frame 18 left-right rotation by the axis of pitch 80 of unitor about single track R goes back except that above-mentioned bending right and left.

Therefore, front and

back chassis

11,12 horizontally rotates by S. A. main body 66 along with the bending of single track R, preceding chassis 11 by above-mentioned center pin 61 and unitor 60 front and back rotate, left-right rotation.

As mentioned above, chassis 11 and back chassis 12 before the chassis that two car-type moving vehicles 100 of present embodiment will carry manned vehicle cabin 16 is separated into, therefore, can between preceding chassis 11 and back chassis 12, form vacancy portion, compare for the situation of one with the car cabin is whole, can reduce the weight of chassis self.Because weight reduces,,, can use ready-made track in the occasion that is equipped with track so the track structure of carrying chassis is lightened.
