Description

[Detailed Description of the Invention] This invention relates to a structure that ensures safety at the side of a vehicle equipped with a drive link.

As is well known, an agricultural tractor, for example, is equipped with a drive link that responds to a pitman arm, and the front wheels are configured to be freely steerable via an interlocking lever on the link.

In this case, the interlocking lever is pivoted on one side of the vehicle body and is configured to directly interlock the tie rod using this as a relay, but in this case the lever remains protruding outward, and all you need is this lever. There is no problem with installing it separately, but when it swings, there are cases where it comes close to the wide front weight, and in such vehicles, if you are working near the same bar, it may cause an accident. There was also a danger that the government would be caught between the two, and an effective solution was needed.

This invention was devised in view of the above, and its characteristics are that an interlocking lever that is swing-operated by a drive link is provided so as to protrude from the outside of the vehicle body, and that the interlock lever and the drive link are connected to each other. The connecting portion of the interlocking lever is configured to approach a fixed portion on the vehicle body side when the interlocking lever is swung in one direction, and a protective cover that covers the connecting portion of the interlocking lever from the outside is provided on the vehicle body side. It is at the point that I have set.

To explain agricultural tractors in detail below, as is well known, this type of tractor has a front engine 1 and a transmission case 2 directly connected to the rear of the engine to form the main part of the vehicle body 3. , engine 1
The vehicle is equipped with a front wheel bearing stand (not shown) projecting forward from both sides of the vehicle, and a front weight bumper 4 mounted and fixed on the upper part of the bearing stand, and is thus wrapped with a bonnet 5 for the purpose of ensuring the safety of the sides. Removable safety covers 6 are provided on both left and right sides.

Such a vehicle body 3 is equipped with a front wheel 7 as a steering wheel, and in order to steer the front wheel 7, a drive link 8 that is moved back and forth by a pitman arm is provided along the left side of the vehicle body 3, and this link The front end of 8 is connected to one end of an interlocking lever 9 formed in a dogleg shape via a ball joint.

The lever 9 is horizontally swingably supported by a relay bracket 10 protruding from the left side of the vehicle body 3, which is located immediately behind the front weight bumper 4.

The other end of the interlocking lever 9 faces the bottom side of the front weight bumper 4, and is connected to a split tie rod 11 in a spherical manner.

In such a vehicle, the front weight bumper 4 is quite wide and has a shape that protrudes outward from the bonnet 5, and the connecting portion 12 of the interlocking lever 9 also protrudes outward.

Therefore, if this connecting part 12 swings forward, it approaches the front weight bumper 4, which is a fixed part, and becomes a platform where the worker's fingers, etc., are held in this space, and if it remains protruded, The exterior design is also unconventional; for example, there is a space left behind the bumper 4, which makes the exterior look somewhat disorganized.

Therefore, in this specific example, the rear cover stay 13 is provided so as to protrude from the bottom of the engine 1 to the left side thereof, and the front cover stay 14 is provided so as to rest on the rear end of the left side of the front weight bumper 4. Protective cover 15 for the U-shaped frame by protruding
It was designed to be detachable.

The upper wall of the cover 15 is L-shaped in plan, and the L
One end of the letter is attached to the rear cover stay 13, and the other end of the letter is attached to the front cover stay 14.

In this case, the lower ends of the bonnet 5 and the safety cover 6 are aligned horizontally, and the front weight bumper 4 and the protective cover 15 are adjacent to each other at exactly the same height in the front and back.
As is clear from the plan view shown in the figure, the side ends are flush with each other.

In this way, the interlocking lever 9 and the front end of the drive link 8 are hidden by the outer envelope of the protective cover 15, so that the operator is not exposed to unexpected harm, and the appearance is continuous. .

The lower part of the front end of the safety cover 6 is connected to the front cover stay 14.
It is said to be removable using the

According to this invention, 1. An interlocking lever that is swing-operated by a drive link is provided so as to protrude to the outside of the vehicle body, and a connecting portion between the interlocking lever and the drive link is connected to one side of the interlocking lever. In a device that is configured to approach a fixed part on the vehicle body side during rocking, a protective cover is provided on the vehicle body side that covers the connecting part of the interlocking lever from the outside. Safety is ensured, and the appearance of the sides also improves.

In addition, the protective cover not only ensures safety, but also has the function of protecting against foreign substances such as grass, straw, and mud.

Note that the protective cover 15 may be integrated with the safety cover 6.
