Description

[Detailed description of the invention] The present invention is a mounting structure for a transfer lever of a four-wheel drive vehicle, and more specifically, a new mounting structure for a transfer lever that operates a clutch for switching the drive system between four-wheel drive and two-wheel drive. Regarding structure.

An example of a four-wheel drive vehicle that can be operated using either four-wheel drive or two-wheel drive is a drive mechanism shown in FIG. 1.

In this drive system, power generated by an engine 1 is transmitted to a transmission 2, and from the transmission 2 is transmitted to front wheels 5, 5 via a final gear 3 and a differential gear 4.
is constantly driven.

On the other hand, the bevel gear 6 combined with the final gear 3 and the bevel gear 8 provided on the rotating shaft 7 mesh to convert the rotating shaft into an orthogonal direction,
A predetermined transfer clutch 9 connects/disconnects power transmission to a propeller shaft 10 leading to rear wheels (not shown), making it possible to switch between two-wheel drive and four-wheel drive.

By the way, the transfer clutch 9 can be connected or disconnected by connecting the transfer rod 11 connected to the clutch 9 to the transfer lever 12 shown in FIGS. 2 and 3, which is disposed protruding inside the driver's cab. This is done by the driver operating the transfer lever 12.

The transmission 2 in FIG. 1 also has a change rod 13 (see FIG. 2), which is not shown in FIG.
It is connected to a change lever 14 in the driver's cab A, and a predetermined speed change is performed by operating the change lever 14.

As shown in FIG. 2, the propeller shaft 10, transfer rod 11, and change rod 13 are disposed within a floor tunnel 16 formed in the floor 15 and extended to a predetermined position. Since the joint portion 17 between the arrow rod 11 and the transfer lever 12 is disposed on the change rod 13, the height H of the floor tunnel 16 becomes high, making it difficult to mold the floor tunnel 16.

Further, the joint portion 17 is connected to the floor tunnel 16.
Because it looked upwards, it also looked unsightly. In the figure, 18 is a driver's seat, and 19, 20, and 21 are a clutch pedal, a brake pedal, and an accelerator pedal, respectively.

The purpose of the present invention is to provide a mounting structure for a transfer lever in a four-wheel drive vehicle that eliminates the above-mentioned conventional drawbacks. The transfer rods are arranged horizontally parallel to each other, and the ends of the transfer rods are introduced into the driver's cab through the side wall of the floor tunnel, and the transfer rods and the transfer rods are placed under the seat of the driver's cab. A joint portion of the transfer lever is arranged, and the transfer lever extends upward from between the seat and the floor tunnel.

Preferred embodiments of the present invention will be described below with reference to the drawings. Note that the same elements as those in the above conventional example are indicated by the same reference numerals.

4 and 5 show an embodiment of the present invention, in which 10 is a propeller shaft, 11' is a transfer rod, 12' is a transfer lever,
13 is a change rod, 14 is a change lever,
15 is the floor, 16 is the floor tunnel, 17'
is the joint between the transfer rod 11' and the transfer lever 12', 18 is the seat, 19, 20,
21 are a clutch pedal, a brake pedal, and an accelerator pedal, respectively.

In this embodiment, as shown in FIG. 4, a propeller shaft 10 disposed within a floor tunnel 16,
Of the transfer rod 11' and the change rod 13, the transfer rod 11' and the change rod 13 are arranged in parallel in the horizontal direction,
The height H of the floor tunnel 16 is set as low as possible.

Further, the floor tunnel 16 is located at a position corresponding to the side surface of the seat 18 of the driver's cab A.
A step portion 22 is formed on the side surface 161 of the step portion 22.
The end 11a' of the transfer rod 11' is formed wider on the engine side (the right side in FIG. 5) than the floor tunnel 16, and the end 11a' of the transfer rod 11' is introduced into the driver's cab A from the floor tunnel 16 at the step 22. and the above sheet 1
The transfer rod 1 is attached to the lower side 181 of the
1' and the joint part 17' of the transfer lever 12', and extend the transfer lever 12' upwardly along the floor tunnel 16 from the part between the seat 18 and the floor tunnel 16. The knob 23 of the lever 12' is arranged on the upper surface of the floor tunnel 16 so as not to interfere with operation.

In this embodiment, since the floor tunnel 16 can be set low as described above, the moldability is good, and the joint part 17' between the transfer rod 11' and the transfer lever 12' is arranged below the seat 18. Therefore, only the upper part of the transfer lever 12' can be seen from the outside, giving it a good appearance.

Furthermore, since the joint portion 17' between the transfer rod 11' and the transfer lever 12' is located inside the operator's cab A, the dustproof and rustproof performance is better than that of the conventional example.

Note that the shape of the joint portion 17' between the transfer rod 11' and the transfer lever 12', the shape of the transfer lever 12', etc. are not particularly limited.
Various changes can be made without changing the gist of the present invention.

In the present invention constructed as described above, the change rod and the transfer rod are arranged horizontally in parallel with each other within the floor tunnel, and the end of the transfer rod is operated by penetrating the side wall of the floor tunnel. The structure is such that the joint part of the transfer rod and the transfer lever is placed in the lower part of the seat in the driver's cab, and the transfer lever is extended upward from between the seat and the floor tunnel. Therefore, the height of the floor tunnel can be lowered compared to the conventional example, which improves the formability of the tunnel, and also improves the appearance because the joint between the transfer rod and transfer lever is not visible. It has a good appearance and is useful because it can improve dustproof and rustproof performance.
