Description

[Detailed Description of the Invention] The present invention relates to an air inlet structure for a cab-over type vehicle that is used as an intake passage for air supplied to the internal space of a cross member and side frame and the engine body.

In a cab-over type car in which the engine is mounted in a position where it is easily exposed to dust and water stirred up by the wheels, internal space such as a side frame is provided to the engine as shown in Japanese Utility Model Publication No. 1982-90827. An air inlet structure has been developed that is used as an air intake passage, thereby allowing relatively clean air from the front of the vehicle to be introduced into the engine body.

The present invention is based on this type of air inlet structure.
A steering shaft through hole for right-hand drive vehicles and a steering shaft through hole for left-hand drive vehicles are provided in the cross member, and the steering shaft is passed through one steering shaft through hole, while the other steering shaft through hole is used as an air intake port. It is characterized by what it did.

The present invention will be explained in detail below based on embodiments shown in the drawings.

Figure 1 shows a pair of left and right side frames 1b and 1a.
A frame structure is shown in which the front ends of each of the two are connected to a cross member 3 via reinforcements 2, 2. side frame 1a of cross member 3,
Steering shaft through holes 4a and 4b are provided at the cross-connection portions with 1b, respectively.

FIGS. 2 and 3 show an embodiment for a right-hand drive vehicle. In this embodiment, the steering shaft 5 is divided into an upper shaft 10 on the steering wheel 9 side and a lower shaft 11 on the steering gear box 6 side, and these are connected by a universal joint 12. is divided into upper and lower parts, and the upper and lower divided parts are joined by a flexible joint 13. The steering shaft 5 is passed through a steering shaft through hole 4a for a right-hand drive vehicle provided on the right side of the cross member 3 at the lower divided portion of the lower shaft 11 thereof. Further, the steering gear box 6 is located directly below the through hole 4a.
is bolted to the bottom surface of the cross member 3.
Numerals 8, 8, and 8 are bolts for this purpose, and nuts 7, 7, and 7 are welded around the through holes 4a, and are screwed into the bolts 8, 8, and 8. The upper divided portion of the lower shaft 11 passes through a hole 16 provided in the floor panel 15, and the flexible joint 13 located at the lower portion thereof is accommodated in the cross member 3 below the floor panel 15. Furthermore, the third
In the figure, 14 is a steering column, and 17 is a cap-shaped seal that seals the gap between the hole 16 of the floor panel 15 and the steering shaft 5.

The upper open portions of the side frames 1a, 1b and the cross member 3 are closed by a floor panel 15 to form a closed space. This internal space is used as an intake passage 19 for air supplied to the engine main body 18, and as shown in FIG. 2, the starting end of the intake pipe 20 of the engine main body 18 faces the internal space of the right side frame 1a. . Then, the through hole that does not allow the steering shaft 5 to pass through, that is, the left-hand drive vehicle through hole 4b, which is a left-hand drive hole, is used as an air intake port, and the air taken in from this hole is drawn in as shown by the arrow in FIG. and leads to the engine body 18. In FIG. 2, reference numerals 21, 21 are closing plates that close the openings at both ends of the cross member 3.

The cross member 3 can be used as it is as a member of a left-hand drive vehicle, and in this case, a steering shaft through hole 4b for a left-hand drive vehicle is used.
The steering shaft 5 is passed through the steering shaft through hole 4a for right-hand drive vehicles.
may be set as the air intake port of the suction passage 19.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, so that the cross member 3 can be commonly used for both right-hand drive vehicles and left-hand drive vehicles, the steering shaft through hole 4a for right-hand drive vehicles and the steering shaft through hole 4b for left-hand drive vehicles are both connected to the side frame 1a. , 1b, but
These may be provided in the vicinity of the cross-coupling portion of the cross member 3.

Since the present invention has the above configuration, the cross member can be used commonly for both right-hand drive vehicles and left-hand drive vehicles, which is advantageous in terms of parts management. Since the hole can be used as the air intake of the intake passage that guides air to the engine body, there is no need to form a special air intake, and the structure can be simplified.
