DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skeletal structure (skeleton structure) bus body.

[0002]

2. Description of the Related Art A skeleton structure (a skeleton structure) in which a stress is applied to a skeleton having a closed cross section is known for a bass body, in contrast to a monocoque structure of a stress skin type.

[0003]

In this skeleton structure (skeleton structure) bus body, the rigidity of the vehicle in the front-rear direction and the up-down direction is high due to the skeleton structure, but the strength of the vehicle body against frontal impact is large. Less than.

An object of the present invention is to provide a skeletal structure (skeleton structure) bus body which solves the above-mentioned problems.

[0005]

The present invention achieves the above objects.
In order to achieve this, in the skeletal structure of the bus body , the supporting beam was connected at the intersection of the side pillar and the beam under the window and the cross beam under the floor that is orthogonal to the front and rear beams under the floor.
It is characterized by.

In a skeletal structure bus body, the intersection between the side pillar and the beam under the side window is perpendicular to the beam under and below the floor.
A support beam is connected through the backrest of the seat across the under-floor cross beam.

[0007] The support beam is provided at the intersection of all the side columns and the beam under the side window, and between the under-front longitudinal beam and the under-floor cross beam.
It is connected over the intersection .

[0008] The supporting beam is an intersection of every other side pillar and a beam below the side window, a beam under the floor, a cross beam under the floor and a beam under the floor.
And the intersection with.

[0009]

According to the above construction, the support beam and the under-floor cross beam bear the stress against the side impact of the body during rollover or the like, and the weight is reduced to improve the strength against the impact from the side direction.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a bus body having a skeleton structure (skeleton structure). The side window 2 of the bus body 1 having this skeletal structure is constituted by side columns 3 and side window vertical beams 4 and 5.

As shown in FIG. 2, the underfloor structure includes a underfloor cross beam 7 and an underfloor front and rear beam 8 intersecting with the underfloor cross beam 7.

Therefore, as shown in FIG. 2, the present invention relates to an intersection 6 between the side column 3 and the beam 5 under the side window, and the front and rear beam under the floor.
The support beam 9 is connected to a beam 8 and an under-floor cross beam 7 orthogonal to the beam 8 . The connecting point of the support beam 9 to the under-floor cross beam 7 is
Intersection 11 between the beam and the beam 8 is appropriate.

Further, as shown in FIG. 3, the support beam 9 may penetrate through the backrest 10 of the seat, and the support beam 9 may be hidden by the backrest 10 of the seat. In this case, the seat through which the support beam 9 passes is not a reclining seat but a fixed seat.

Further, the supporting beam 9 is provided on all the side columns 3.
6 may be joined across the intersection 6 between the beam 5 under the side window, the cross beam 7 under the floor, or the intersection 6 between the side pillars 3 and the beam 5 under the side window, and the cross beam 7 under the floor.

The connection of the support beam 9 is performed by welding, bolting, riveting, or the like.

Since the present invention has a structure as described above, a right angle portion formed by the side pillar 3 and the under-floor cross beam 7 is formed by the truss structure by the supporting beam 9.
The supporting beam 9 and the under-floor cross beam 7 bear the impact stress from the side surfaces of the side pillar 3 and are reinforced against deformation of the lower portion of the side window of the side pillar 3.

Further, when the support beam 9 is penetrated into the seat backrest 10 and is connected thereto, the support beam 9 is hidden by the seat backrest 10, so that the support beam 9 is not exposed in the vehicle interior and the appearance is impaired. Nothing.

The setting of the support beam 9 is performed by the bath body 1
Depending on the size of the beam, the intersection 6 between all the side pillars 3 and the beam under the side window 5 and the cross beam 7 under the floor, or the intersection 6 between every other side pillar 3 and the beam 5 under the side window and the cross beam 7 under the floor Combined across.

[0019]

As described above, the present invention relates to a bus body having a skeletal structure, in which an intersection between a side pillar and a beam under a window is positioned in front of a floor.
In the configuration of claim 1 that combines the beam support across the floor cross beams are perpendicular to the rear beam, in Basubode skeletal structure (skeleton structure), the deflection of the body sidewall by rollover or the like <br/> is In addition to preventing the impact from the side, the beam and the under-floor cross beam bear the stress by supporting the impact from the side, and have an advantage that the weight can be reduced and the strength against the impact from the side can be improved. In addition, the support
