The innovation associates, on the one hand, to a hydro technical equipment box with a hydraulic pump, a coupling hydraulic. A set of planetary equipment, the pressure range of the hydraulic pump is performed back, via the placed coupling hydraulic, to the suction power range of the hydraulic pump, thereby developing a routine. The sun rim or the planet-carrier of the set of planetary equipment is combined in a rotationally set way to the motivated base of the equipment box, and the other one of these two components of the planetary equipment is combined in the same way to the outcome base of the equipment box.
A sequence of equipment box designs, which also include the hydraulic equipment box in which a hydraulic pump a coupling hydraulic via an oil routine, have become known from the before art. In hydraulic gearboxes of this kind, however, the performance decreases rapidly with rising spinning rates of speed, since circulation resistances make themselves experienced in a disadvantageous way as the rate of circulation of the hydraulic oil improves. Consequently, a particularly lots of power is lost accurately when the highest possible outcome is required of the equipment box, with the outcome that the internal-combustion motor engine providing the drive has to be over dimensioned to a relatively major level.
These disadvantages of the preparations known from the before art outcome in the issue, which is starting the present innovation, of developing an considerably varying equipment box which produces it’s the best possible performance accurately when the highest possible throughput of power happens.
These disadvantages of the preparations known from the before art outcome in the issue, which is starting the present innovation, of developing an considerably varying equipment box which produces it’s the best possible performance accurately when the highest possible throughput of power happens.
This issue is fixed in an equipment box of the above described kind, when one spinning device of the coupling hydraulic, ideally its blades, is combined in a set way to the motivated base of the equipment box. In addition, the other device of the coupling hydraulic, ideally its fixed aspect, is combined either to the frame/housing of the equipment box or to its outcome base. As will be further described later on, in an agreement of this kind, the distribution number of the hydraulic pump decreases as the spinning rate of the outcome base improves, until it finally becomes absolutely zero at a highest possible spinning rate.
This means that, at great spinning rates of speed at which the greatest outcome is taken off at the outcome base, no circulation failures occur in the hydraulics and therefore the performance gets to its highest possible. Because of its positive performance, an equipment box of this kind allows a reduction in the architectural size of the driving motor.
The innovative hydro technical equipment box offers the chance of managing the rate of an automobile through the equipment rate, while the burning motor operates at a nearly continuous rate, where the twisting is as great as possible or its performance has its best value. The dynamical features of the innovative equipment box are excellent, because at a halt of the automobile the hydraulic pump operates at a high-speed, so that a lot of spinning power is saved within its spinning public. When the automobile begins, these spinning public are decelerated, whereby the saved number of power is provided at the outcome base additionally to the quality of power, which is directly passed on from the burning motor. Therefore, at this time, when the automobile begins, the innovative hydro technical equipment box may have a performance of more than 100%. This aspect is very important for vehicles for farming reasons, which function often at a difficult or extreme scenery. If the tractor has to start from a prepared position, at this time of disconnecting the braking mechanism the equipment box has to provide the full outcome at its outcome base.
One possible way of modifying the gearing rate of the equipment box according to the innovation comprises in the fact that the distribution number of the hydraulic pump is flexible. With the intake number of the coupling hydraulic the same, it is possible, by modifying the distribution number of the hydraulic pump, to change the stopping action of the latter and in this way achieve an modification of the gearing of the equipment box. Axial aide pumps, for example, are suitable for this objective since, in the situation of these pumps, the tendency of the indirect disk actuating the axial aide is flexible during function. Axial control cylinders, which are connected to the pump covering in a rotationally set way, are used for this objective.
