Description

248 546 1

  Multipurpose self-propelled agricultural vehicle,

with mobile driver's cabin.

  The invention relates to a multipurpose agricultural vehicle, in particular a tractor comprising a control station in the form of a driver's cabin, in

which are arranged control and ac-

  tction which coupling with the vehicle is ex-

clusively in a flexible manner, as for example by

  electric cables or hydraulic and pneumatic hoses

ticks.

In a multi-purpose vehicle, as known from

German patent 1,949,978, the driver's cabin is mon-

  tee on a swivel arm which can be swiveled in two

positions and be locked in the desired positions.

The disadvantage of such a constitution lies in the fact that during a relatively large reach of the arm

swivel, it must have a very large dimension

  bearing to give it a resistance that ensures safety

rity vis-à-vis the reversal required by the standards. Another disadvantage lies in the fact that between the cabin, when it is pivotally mounted in the region

  of the oscillating axle of a multi-purpose vehicle for

  put to observe for example a hash unit attached to it, and the work tool, appear, consequently

  unevenness of the ground, relative movements which

  due to driver discomfort and in some cases also

  to discomfort from. freedom of movement of tools

cabin work. Therefore, the present invention

  tion intends to provide a versatile vehicle of the type described above and satisfactorily meeting the

requirements imposed on it, in particular as regards

identifies a robust and simple constitution.

  This is obtained according to the invention thanks to the fact that

  the driver's cabin can be separated from the parts

aunts of the vehicle, can be coupled and blocked on the vehicle as desired in at least two fixed receiving members on the vehicle, or that the driver's cabin can be coupled and blocked on the working tools carried -2-

or driven by the vehicle.

  According to another characteristic of the invention, advantageously, at least one respective receiving member for the driver's cabin is fixed both on the chassis and on an axle of the multi-purpose vehicle, and a

  lifting and rotating drive device,

  before being coupled to the driver's cabin, is provided separately from the receiving members. The advantage of such a constitution essentially lies in the fact that

  the lifting device itself is only used when

that the cabin must pivot. Correspondingly, it can have small dimensions. The plates arranged in a distinct manner offer the advantage that they are rigidly coupled with the chassis or respectively with an axle, so that on the one hand one is assured of a fixed hold by simple locking mechanisms. On the other hand, it is possible to couple the cabin support with the vehicle in isolation from the point of view of noise in the

  solids, since it is not coupled with the dis-

  positive lifting in its working position.

  Another problem may arise when the wheels are

  of the vehicle concerned have a large diameter, from

  so you get a total height that can go up to

only about four meters. Transportation of such vehicles

by rail or by lowered trailer is not

  ble most of the time that by dismantling the cabin, which

  requires the interruption of all couplings. This if-

  involves long assembly work on the loading sites

handling and unloading.

  Consequently, the present invention also proposes

  Lement to arrange a multipurpose agricultural vehicle of the type described above so as not to have to dismantle the

  cabin to transport the vehicle.

  This is obtained according to the invention thanks to the fact

  that one of the vehicle's axles is coupled to an auxiliary chassis

  liaire on which can be placed the driver's cabin,

the support plane of the auxiliary chassis being located sensitive-

  at the same distance from the ground as the vehicle axles, -3-

  and that the controls from the cab to the vehicle

  are electric, electronic, pneumatic or hydraulic, and are long enough for their

  coupling with the vehicle is ensured even when the

bine is placed on the auxiliary chassis.

  The advantage of such a constitution is that the

conductor bin can be easily deposited on the

  intermediate chassis, by means of an existing crane

time share at the place of loading or a cart-

  stacker, and remains maneuverable independently. The vehicle

  versatile cule can therefore be mounted and lowered from the wagon

loading without foreign aid.

Advantageously, at the rear axle of the vehicle

versatile is coupled to a three-point hitch on the-

  which the auxiliary chassis is removably attached.

We get in this way that they are the same

  attachment points for working tools in front of event

  be dismantled at the place of use and for

the auxiliary chassis.

To prevent the driver's cabin from slipping from the auxiliary chassis during transport while it is in it, the auxiliary chassis is fitted with a

  locking. In an advantageous embodiment, this

  this consists of pins coupled to the auxiliary chassis

  liar and on which sleeves can be placed

lock welded on the cabin.

  The present invention will be better understood using

of the invention.

  Reference 1 designates the chassis of a poly-

  have the value 2 which is carried by the front steering axle 3 and the rear oscillating axle 4, a three-point hitch, not shown, being coupled to the oscillating axle 4. To the chassis 1 is rigidly coupled a support plate 5 which has four pins 6 whose section decreases towards

  the top. On these pins 6 are placed pieces of adjustment

stage 7 which are rigidly welded, by means of joint plates 8, to an intermediate chassis 9. The intermediate chassis 9 comprises external brackets on which are oscillating rubber elements 11. The other side of each element rubber 11 is fixed on the joint plates 12 which are welded

  on the chassis 13 proper of the cab 14 of the conduc-

  tor. To prevent the adjustment parts 7 from coming off-

  fortuitously feels pins 6, these adjustment pieces 7 have slots 15, two respective slots serving

  guiding a locking strip 16 and respecting

  vement 17. The two locking strips are coupled

  articulated to a linkage 18 which supports the

  plates 16 and 17, by means of the force of the spring 19 of which

one end rests on the chassis 9, in recesses

  ments 20 of the pins 6, through the slots 15, and consequently the pins 6 are locked with the adjusting pieces 7. To undo the locking, the rod 21 of the linkage 18 is pulled in the direction of the arrow A (FIG. 6) against the force of the spring 19, by actuating a bent lever 22 which is mounted so

pivoting in a console 23 welded to the chassis 13.

One end of this bent lever 22 engages behind a pin 25 mounted in a fork 24, while the other

  end is raised by means of an adjustable stop 26.

  As seen in Figure 6, on the intermediate chassis

  diary 9 are screwed stops 27 which are used to actually exit the locking strips 16 and 17, coupled

  articulated to the linkage 18 only by the

  through a respective lever 28 and 29, recesses

  20. On the other hand, these stops limit the path of the rulers-

  your 16 and 17, so that they are worn permanently

  nence through the slots 15 of the adjustment pieces 7. Being given

born that the rod 21 is also slidably mounted

te in chassis 9, 13, the whole locking mechanism

  is coupled to the driver's cabin 14.

As seen in Figures 1 and 2, on a lanyard

  frame 1 is mounted a hydraulic unit or tire-

  material 30 with cylinder and piston, on which is fixed a support arm 31. This support arm 31 is equipped with two gripping members as well as an adjustable stop 26 (FIG. 4). If then the cabin 14

from the position shown in solid lines on the figure

re 1, in the position shown in dotted lines, the unit

cylinder and piston is raised. Therefore, all of a-

edge the angled lever 22 pivots under the action of the stopper 26

  and the chassis 9 is unlocked from the plate 5. Simulta-

  Finally, the gripping members 32 engage in two lifting pockets 33 rigidly coupled to the driver's cabin 14 and lift the cabin 14 from the pins 6. Then,

  the cabin 14 pivots, either by rotating it manually-

  This is due to the fact that the cylinder and piston unit is in the form of a cylinder and rotary piston unit, around the vertical axis of the unit 30 until it arrives on a second support plate 34 which,

  like plate 5, is also equipped with pins 35.

  The cabin 14 is then placed on these pins 35 and, because the stop 26 moves down and releases the bent lever 22, is again locked under the action of the spring 19. As can be seen in FIG. 2 , the plate 34 is offset laterally so that on the one hand it

248 546 1

  sufficient space remains for mounting work tools

  vail, and that on the other hand the plate 34 protrudes beyond the chassis 1, so that the driver sees directly

  the work tools in place. Because both the

  til that must be mounted that the plate 34 are coupled di-

  directly to the oscillating axle 4, respectively via the three-point linkage not shown and

  through a tube 37, there does not appear any

  relative relative between the cabin and the working tool, this

  which makes it much easier for the driver to observe the

worn.

  Figure 1 shows that a flexible hose 36 leaves the cabin 14 to reach the vehicle. In this pipe 36 are housed all the control members and conductors which are

  necessary for operation. All control bodies

  from and from the cabin to the vehicle are exclusively of the electrical, electronic, hydraulic or pneumatic type. In this way, the pivoting of the cabin

  is possible without having to decouple control elements

  any. Another advantage is that

  the cabin is coupled to the vehicle without transmission bridges-

  noise in solids. For this purpose are also

  provided the oscillating rubber elements 11.

  As can be seen in FIG. 3, instead of the tube 37 used in FIG. 1 for fixing the plate 34,

  one can provide two tubes 38 and 39 engaging telescopically

  only one inside the other, the tube 38 being coupled to the or-

  receiver gane 40. Tubes 38 and 39 can be removed

  from each other via a unit 41 with cy-

  lindre and piston arranged in the tube 39, so that the driver has even better visibility. The organ

  receiver 40 is constituted by a plate 42, provided with a guide

  and rigidly coupled to a square tube 39, on which

  the plate 43, fitted with receiving pins 44 for the ca-

  bin is mounted so that it can be moved in the

  indicated direction but also in a perpetual direction

  dicular, and able to be blocked. By moving the ca-

  bine, the driver can then adjust the observation position

  most suitable for him.

  In the embodiment of FIG. 7, the reference

  rence 51 designates a multi-purpose vehicle for work

  agricultural, reference 52 designates a cabin for the con-

  conductor which, during the use of the machine, is

  born in one of the two positions represented in lines

  mixed, depending on whether the vehicle is used

  Read as a tractor or as a driving machine with a chopper mounted on the rear swing axle 53. As can be seen in the figure, on this swing axle 53 is

  fixed an auxiliary chassis on which the cab 52 of the

  ductor can be placed, for example for transport by

  railway track, so as not to exceed the allowed gauge-

  sible. The transfer of the cabin from one of the two

  working positions on the auxiliary chassis 54 are effected

  kills using a crane, forklift, or similar device. The seating plane of the auxiliary chassis 54 is substantially at the same distance from the ground as the oscillating axle 53. To lock the cabin 52 with the auxiliary chassis 54, the latter comprises several pins 55 whose section decreases in a cone towards the high and which engage in locking sleeves 56 coupled to the cabin. Between the cabin 52 and the vehicle extends a flexible hose 57 which surrounds all the control and transmission elements to protect them. Control and transmission elements are exclusively of the electrical, electronic, pneumatic or hydraulic type, so that they do not need to be removed when the cabin 52 is placed on the auxiliary chassis. This has the great advantage that the vehicle can be raised and lowered from a railway wagon with its own strength. This also saves time-consuming assembly of control elements and

of transmission.

  As it goes without saying, and as it already follows from the above. the invention is in no way limited to those of its modes of application and embodiments which have

  have been more particularly envisaged; she embraces it,

milk, all variants.
