One of purpose of the utility model is to have overcome defective of the prior art, and a kind of good maneuvering performance that has is provided, the easy vehicle body that is used for special vehicle through narrow curved area and cut-through thing.
Two of the purpose of the utility model is to have overcome defective of the prior art, and a kind of good maneuvering performance that has is provided, and passes through the special vehicle of narrow curved area and cut-through thing easily.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of vehicle body that is used for special vehicle; Comprise body shell, body shell comprises at least two joint car body, and the equal correspondence of every joint car body is provided with one group of wheel; Connect through connecting device between the car body; Connecting device comprises steering shaft, and in the same side of body shell, the center of the wheel of last joint car body equals the center of wheel of back one joint car body to the vertical distance of the line of centers of steering shaft to the vertical distance of the line of centers of steering shaft.
Further, vehicle body comprises two joint car body.
Further, two joint car body are respectively headstock and towed vehicle envelope.
Further, vehicle body comprises three joint car body.
Further, three joint car body are respectively headstock, the first towed vehicle envelope and the second towed vehicle envelope.
Further, link arm and back link arm before connecting device comprises, preceding link arm is hinged through steering shaft with the back link arm.
A kind of special vehicle includes vehicle body, and vehicle body is the above-mentioned vehicle body that is used for special vehicle.
Compared with prior art, the beneficial effect of the utility model is:
A kind of vehicle body that is used for special vehicle; Comprise body shell, body shell comprises at least two joint car body, and the equal correspondence of every joint car body is provided with one group of wheel; Connect through connecting device between the car body; Connecting device comprises steering shaft, and in the same side of body shell, the center of the wheel of last joint car body equals the center of wheel of back one joint car body to the vertical distance of the line of centers of steering shaft to the vertical distance of the line of centers of steering shaft.Two joint car body turn radiuss are identical before and after making, promptly the front and back wheel travel track is identical.Therefore, when the lane during with the cut-through thing, as long as the frobt vehicle envelope can pass through lane and cut-through thing, then the rear vehicle envelope also can pass through lane and cut-through thing smoothly, the maneuvering performance of vehicle so be greatly improved.

The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
A kind of vehicle body that is used for special vehicle; Comprise body shell, body shell comprises at least two joint car body, and the equal correspondence of every joint car body is provided with one group of wheel; Connect through connecting device between the car body; Connecting device comprises steering shaft, and in the same side of body shell, the center of the wheel of last joint car body equals the center of wheel of back one joint car body to the vertical distance of the line of centers of steering shaft to the vertical distance of the line of centers of steering shaft.
Concrete, like Fig. 1, shown in Figure 2, vehicle body comprises two joint car body.Two joint car body are headstock 1 and towed vehicle envelope 2.Headstock 1 is driving wheel 6 and trailing wheel 7 before correspondence is provided with respectively with towed vehicle envelope 2, link arm 4 and back link arm 5 before connecting device comprises, and preceding link arm 4 is hinged through steering shaft 3 with back link arm 5.As shown in Figure 1, the center of the preceding driving wheel 6 of headstock 1 is a to the vertical distance of the line of centers of steering shaft 3, and the center of the trailing wheel 7 of towed vehicle envelope 2 also is a to the vertical distance of the line of centers of steering shaft 3.When turning, the centre plane of preceding driving wheel 6 is identical with the trace radius r that the centre plane of trailing wheel 7 rolls across on supporting plane at the trace radius r that rolls across on the supporting plane, and promptly the front and back wheel travel track is identical.
