Definitions

  • the invention relates to an agricultural tractor of the type described in more detail in the preamble of claim.
  • Such agricultural tractors are very often used as a tractor for agricultural machines, e.g. Combine harvesters, maize harvesters, harvesters and the like. All of these agricultural machines only work with optimum efficiency if the speed transferred from the PTO shaft to them is always constant.
  • the speed of the PTO shaft depends on that of the tractor's motor shaft, i.e. ultimately on its driving speed. If its driving speed drops below normal speed, the speed of the PTO shaft, which is driven via the crankshaft of the tractor engine, inevitably also decreases.
  • the reduction in speed of the PTO shaft in turn results in a reduction in the speed required for the operation of the agricultural machine. This inevitably reduces the efficiency and thus the performance of the agricultural machine.
  • the invention is now based on the idea of taking a measure by means of which the same operating speed can always be maintained for the agricultural machine, regardless of the speed of the crankshaft of the engine and thus also of the driving speed of an agricultural tractor.
  • a gear is arranged on the tractor, the drive shaft is connected to the PTO shaft and the output shaft can be connected directly to the machine and that the gear lever with the gear lever is connected in such a way that when the fuel supply changes Normal load in the direction of low load, the gear ratio of the transmission can be changed so that the output shaft always has the same speed regardless of the speed of the agricultural tractor.
  • the agricultural working machine can always be operated at its most economical output and the area output can thus be optimized.
  • FIG. 1 is a view, partly in section, of the agricultural tractor according to the invention at normal speed
  • Fig. 2 is a view, partly in section of the tractor according to the invention at a driving speed below the normal speed.
  • the drawing shows an agricultural tractor with the drive motor 1 and the gear shift transmission 2, the gears of which can be shifted via a shift stick 3.
  • An injection pump 4 is arranged on the drive motor 1 and is connected to the associated cylinders via lines 5.
  • a gear wheel 7, which is fastened to the power take-off shaft 8, can be set in rotation via the preliminary shaft 6 of the gear shift transmission 2.
  • a clutch to engage this PTO 8 is a clutch, not shown, by means of which the gear 7 can be brought into and out of engagement with the gear 9 of the countershaft 6.
  • the drawing shows only a single PTO 8, the invention is in no way limited to this; rather, it can also be used on agricultural tractors with additional PTO shafts, such as front or side PTO shafts.
  • a tractor 10 is arranged on the agricultural tractor, the drive shaft 11 of which is connected to the PTO shaft 8 and the output shaft 12 of which is directly connected to the agricultural machine, e.g. to a combine harvester Like. Can be connected, which is not shown in the drawing for reasons of clarity.
  • Ge gear is to be understood in the broadest sense of the word.
  • the embodiment in Figures 1 and 2 shows a continuously variable transmission.
  • This Ge gear 1o initially has two spaced disc halves 13, 14 which are connected to the drive shaft 11.
  • the drive shaft 11 is rotatably mounted in the housing of the transmission 1 o.
  • the two disc halves 1 3, 14 are assigned two disc halves 15, 16, of which the disc half 16 is connected to the output shaft 12, while the disc half 15 is in a fixed connection with a shaft 17.
  • the two shafts 12 and 17 are also rotatably mounted in the housing of the transmission 10.
  • the distance between the two disc halves 15, 16 can be increased or decreased via a linkage mechanism, so that these two disc halves 15, 16 can move away from one another or move towards one another.
  • two pivot levers 18, 19, which are articulated in the housing of the transmission 10 are used. These are in an articulated connection with sleeves 2o, 21 which, when actuated, do not prevent the rotational movement of the two disc halves 15, 16, but nevertheless allow the same to move axially.
  • sleeves 2o, 21 which, when actuated, do not prevent the rotational movement of the two disc halves 15, 16, but nevertheless allow the same to move axially.
  • At one end of each pivot lever 18, 19 links 22, 23 are articulated, which with a two armed pivot lever 24 are in an articulated
  • a pull rod 26 is articulated at points 27, the end of the drawbar 26 opposite this articulation point 27 being articulated at points 28 with a shift lever 29 which is pivotably mounted at point 30.
  • a rod 31 is articulated on the shift lever 29, via which the regulator 32 for the injection pump 4 can be adjusted.
  • the two disc halves 13, 14 and 15, 16 form keyways for receiving a V-belt 33.
  • the countershaft 6 drives the PTO shaft 8, which has, for example, a speed of 68 ° rpm.
  • the downstream adjustment gear is designed so that the output shaft 12 has a speed of 54o U / min. This constant speed is the most economic speed for the operation of the agricultural machine pulled by the tractor.
  • the individual parts of the adjustment gear or the tractor take up the position shown in FIG. 1.
  • the controller for the injection pump 4 is adjusted so that the individual cylinders receive less fuel per unit of time. This has the consequence that the agricultural tractor moves more slowly and thus the speed of the PTO shaft 8 and thus inevitably also that of the output shaft 12 drops, for example to 48 ° rpm. At this speed, however, the agricultural working machine pulled by the tractor no longer works optimally. So the optimal one applies To reach speed of 54o U / min again.
  • the design of the transmission 10 is a matter for a person skilled in the art. It should be taken into account that such transmissions are commercially available as so-called "adjusting drives or PIV transmissions". They are characterized by adjustable pulley halves, to which two non-adjustable pulley halves are assigned, the two pulley pairs being connected to one another via a V-belt, a rope or a chain. The transmission ratio and thus the output speed can be regulated continuously by axially displacing the two disc halves.
  • the starting point for the invention is the consideration that the agricultural machines pulled by the agricultural tractor, for example combine harvesters and the like, only work with optimum efficiency if the speed transmitted to them by the PTO is always constant.
  • the speed of the PTO shaft depends on the engine speed of the agricultural tractor and thus also on its driving speed, the speed of the PTO shaft decreases, for example, when the engine speed of the agricultural tractor becomes lower.
  • the speed of the speed required for driving the agricultural machine also decreases, which inevitably leads to a reduction in the performance of the agricultural machine.
  • the application is based on the task of taking a measure by means of which the same operating speed can always be maintained for the agricultural working machine, regardless of the speed of the crankshaft of the engine and thus also of the driving speed of the agricultural tractor.
  • a step-by-step speed change gear (2) is provided between the tractor engine (1) and the continuously variable transmission (1o) in that the drive shaft (1) of the transmission (1o) with the PTO shaft which can be driven by the tractor engine (8) and its output shaft (12) can be connected directly to the machine and that the gear lever (29) is connected to the shift lever (29) in such a way that when the fuel supply changes from normal load to low load, the gear ratio of the gearbox ( 1o) can be influenced such that the speed of the output shaft (12) is the same regardless of the speed of the agricultural tractor.
  • the agricultural work machine and thus the area performance can be optimized by the proposal according to the invention.
  • the multi-stage transmission works like a continuously variable transmission, so that a continuous change in the driving speed is possible between the individual gears of the multi-stage transmission.

Abstract

Pour pouvoir maintenir constante la vitesse de rotation d'une machine agricole tractée indépendamment de la vitesse du tracteur, il est prévu de disposer sur le tracteur une boîte de vitesse (10) dont l'arbre d'entraînement (11) est relié à la prise de force (8) et dont l'arbre de sortie (12) peut être relié à la machine agricole. La boîte de vitesse (10) est reliée au levier de commande (29) de manière que le rapport de multiplication de la boîte de vitesse (10) soit modifiable par une modification de l'arrivée du combustible de l'alimentation normale vers une alimentation plus faible, que l'arbre de sortie (12) ait toujours la même vitesse de rotation et qu'une modification de la vitesse du véhicule sans-à-coup soit possible entre les vitesses de l'engrenage réducteur (2).
