Device for attaching work implements to vehicles, in particular vehicles used for agriculture

The invention relates to a device for the cultivation of implements with the features as they are in The preamble of claim 1 are listed.

When attaching an implement via a three-point linkage, there is a requirement that it be pivotable or should be arranged in a laterally stable manner.

Various devices have become known with which this requirement is to be met. From the DT-AS 1 179 030 shows such a device in which the lower one, which can be pivoted laterally in the same direction Handlebars are limited in their rotational mobility by a kind of claw coupling. The well-known However, the device has the disadvantage that the limitation of the rotational movement of each auxiliary link as a function is made by the twisting of the other. In addition, a relatively large amount of space is required at the rear of the tractor, whereby the field of application of this device is limited.

The object of the invention is therefore to provide a device for limiting the lateral mobility of the lower link to create, which requires little space and in which further a stepless adjustment of the areas in where lateral mobility is desired or not desired, can be made.

This object is achieved according to the invention in that the side supports are mounted on cranks, in whose movement paths at least one adjustable stop is arranged engaging. One of those constructed device can be kept much narrower in its overall width than with the previously known devices was the case. The invention is particularly with one. Schraal-track tractor to use with advantage.

According to a further feature of the invention, the cranks are on a bolt that is fixed to the vehicle between Storage brackets is arranged, mounted pivotably. In connection with a continuously adjustable The adjusting spindle allows the cranks to move freely and independently of one another vary.

Further advantageous features can be found in subclaims 3 and 4.

The invention is explained below using an exemplary embodiment with the aid of the drawings.

Here show:

Fig. 1 is a plan view of the lower links of a three-point linkage and their articulation on a bearing bracket

509815/0739, _

Fig. 2 shows a further detail of the articulation according to Pig. 1 in front view.

Of the device for attaching work equipment to agricultural vehicles are only the two lower links 1 and 2 are shown. The lower handlebars. 1 and 2 are part of one Narrow gauge tractor, which itself is not shown, and widen cranked ends 3, which the also include not shown lower connection points for the implement. ι

A bearing bracket 4 carries bearing blocks 5,6,7 and 8 for the two lower links 1 and 2. The lower ones Handlebars 1 and 2 are here in a conventional manner via a bearing ball 9 and 10 each on one Bearing pins 11 and 12 are arranged to be pivotable. Here, the bearing bolts 11 and 12 are from the bearing blocks 5 and 6 or 7 and 8 added.

With the first bearing bracket 4, further bearing brackets 13 and 14 are firmly connected to one another. The bearing brackets 13 and 14 are penetrated by bores 15 and 16 through which a bolt 17 is passed. On this stud 17 cranks 18 and 19 'formed from panels 20 and 21 and pins 22 and 23 rotatably mounted. The pins 22 and 23 take the connection points 24 and 25 of lateral supports 26 and 27 on. The lateral supports 26, 27 are firmly connected to the lower links 1 and 2 by means of fastening screws 28.

The bearing brackets 13 and 14 also carry a nut 29 _f through which an adjusting spindle 30, which acts as a stop, is passed.

• τ

The operation of the device described is as follows:

In the event of a pivoting movement of one of the lower links 1 or 2, the lateral support 26 or 27 rotates the crank 18 or 19 · The pivoting movement of the crank 20 or 21 is · by the adjusting spindle 30 optionally limited, since this is arranged engaging in the movement path of the crank 18 or 19. The amount of permissible lateral movement of the lower links 1 and 2 is thus continuously variable, but can also become zero as required.

In the raised position of the lower link 1 and is their lateral mobility by further stops 31 and 32 limited. These stops 31 and 32 are preferably arranged on the cranks 18 and 19.
