Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a steering section structure for an agricultural tractor.

[Conventional technology]

Generally, the steering section of an agricultural tractor has its steering wheel shaft located behind the instrument panel.
The steering wheel shaft is roughly divided into two types: a structure in which the steering wheel shaft is provided in an exposed state, and a structure in which the steering wheel shaft is provided in a state in which the steering wheel shaft passes through the instrument panel.

[Problem that the invention attempts to solve]

Considering the above two configurations, if the steering wheel shaft is located behind the instrument panel, the distance between the instrument panel and the driver increases, which not only makes it difficult to read the instruments on the panel, but also makes it difficult to read the instruments on the panel. There is a problem in that the driving section becomes narrow due to the space for installing the shaft.

Therefore, it is desirable to have the handle shaft pass through the instrument panel, but this configuration requires a lot of effort when manufacturing the tractor, such as moving the instrument panel from above to below so that the handle shaft passes through. Furthermore, when inspecting or repairing the handle shaft, etc., the handle shaft cannot be exposed unless the instrument panel is removed, which is time-consuming.

The present invention was developed in view of the above circumstances, and provides a steering section structure that eliminates the above-mentioned disadvantages by rational modification without impairing the advantages of the structure in which the steering wheel shaft is provided through the instrument panel. It has a purpose in that it does something.

[Means for solving problems]

The features of the present invention are that a recess into which the steering wheel shaft is inserted is formed on the rear edge of the instrument panel, and the steering wheel shaft cover protruding from the instrument panel is divided into two halves, at least on the rear side. The handle shaft cover part of the is configured to be detachable from the instrument panel, and the rear handle shaft cover has a
The present invention is provided with an extended portion that closes the recessed portion from the rear, and its functions and effects are as follows.

[Effect]

In other words, since the steering wheel shaft is inserted into the recess on the rear edge of the instrument panel as described above, the steering wheel shaft can be positioned in front of the driving section, making it possible to make the driving section wider. Since the distance can be shortened, it is easier to read the instruments on the panel.

In addition, as mentioned above, since the concave part of the instrument panel is closed by the rear handle shaft cover, it is possible to prevent dust from entering through this concave part, and the instrument panel can be easily removed by simply removing the cover. You can also expose the steering wheel shaft by simply removing this cover.

Furthermore, for the same reason, when manufacturing a tractor, there is no need for a procedure such as moving the instrument panel from above to below, and the instrument panel can be attached after attaching the steering handle to the handle shaft, thereby saving time and effort.

[Effect of idea]

Therefore, with a simple structure such as forming a recess in the instrument panel and providing a cover that closes this recess, it is possible to easily remove the instrument cover or expose the steering handle shaft without compromising the advantages of the conventional technology. As a result, it is possible to easily inspect and repair instruments and the steering section, and a steering section structure has been provided that allows easy installation of an instrument panel and a steering handle shaft when manufacturing a tractor.

Further, by providing the handle shaft cover, the recessed portion of the instrument panel is closed from above, and the appearance is excellent.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 4, an engine 3 and a clutch housing 4 are mounted on the front part of the vehicle body on which the steering front wheels 1 and the driving rear wheels 2 are mounted, and a transmission case 5 is mounted on the rear part of the vehicle body. A driving section A consisting of a steering handle 6 and a seat 7 is provided in the center of the tractor to form an agricultural tractor.

As shown in FIGS. 1 to 4, the engine 3 is disposed within an engine bonnet 8, and a hood 9 is connected to the rear of the bonnet 8. As shown in FIGS. A fuel tank 10 is provided above and behind the engine 3, and this tank 10 is connected to a stay 12 extending upward from the vehicle body frame 11.
installed on.

Further, the steering handle 6 has two steering handle shafts 13, 13 and a joint 1.
The rotation operation force of the steering handle 6 is linked to the power steering box 15 attached to the vehicle body frame 11 via the power steering wheel 4, 14, and drives and oscillates the pitman arm 16 of the box 15.
A front wheel knuckle arm (not shown) is configured to be operated via a drag link 17 connected to this arm 16.

Of the handle shafts 13, 13, the upper one has a boss 18 externally fitted onto the shaft 13 to stabilize its rotation axis, and this boss portion 18 is attached to the bracket 1.
A fuel tank 10 is attached via 9.

Further, the upper handle shaft 13 is provided so as to penetrate through an instrument panel 20 provided at the front of the operating section A. That is, the instrument panel 20 has a recess 20a formed in its rear edge, and the panel 20 is fixed to the hood 9 with screws 21, with the handle shaft 13 being inserted into the recess 20a.
In addition, a handle shaft 13 vertically passes through the panel 21.
is covered from the front and back by two handle shaft covers 22a, 22b, and the rear cover 22b is provided with a downwardly extending portion 22c so as to close the recess 20a from the rear.
2b is fixed to the instrument panel 20 with screws 23.

Then, check or repair the steering handle shafts 13, 13 or the instruments 24 of the instrument panel 20.
As shown in FIG. 3, inspection and repair is carried out by removing the rear cover 22b to expose the handle shaft 13 and removing the instrument panel 20 forward.

[Another example]

In this embodiment, the front handle shaft cover 22a is attached to the instrument panel 20 with screws 23, but it may be fixed to the instrument panel 20.
