  • the pressure setting takes place in the expansion tank, which in fluid communication with the gearbox is stationary, so the pressure within the expansion tank with the pressure in the transmission housing corresponds.
  • expansion tank at least partially is filled with gear oil, which serves as a fluid for pressure change serves.
  • a second fluid is provided, which via a separating element, such as a piston, a membrane or bladder separate from the transmission oil.
  • the second fluid which is preferably air, also serves to compensate for temperature fluctuations that occur during operation of the transmission oil.
  • an attenuator is provided by the in particular a pressure transfer to the transmission oil dampable is, wherein the attenuator, in particular a separating element with arranged spring or a proposed gas volume having.
  • a pressure sensor is provided which is in signal communication with the control device. So can be measured by an external pressure sensor, the ambient pressure and forwarded to the controller. Based of these measured values, the control device can measure the internal pressure of the Adjust housing in the desired manner, with an internal pressure sensor can serve as a feedback device. So it can not only a pure control but also a regulation of the Internal pressure.
  • Another preferred embodiment of the invention is in that an oil level measuring device for detecting a Gear oil level is provided in the expansion tank, the in particular with the control device in signal connection stands.
  • the gear oil level in the reservoir can be particularly easily detected and for reliable oil level measurement be used.

  • the method according to the invention is characterized that the internal pressure is changed by means of an active actuator which is controlled by a control device becomes.
  • an external pressure on the transmission housing is measured and the internal pressure in dependence on the measured External pressure is controlled. Due to the small size and the relatively low cost of pressure sensors preferably also be provided a plurality of external pressure sensors, so that a particularly high measuring reliability is guaranteed.
  • the external pressure can be approximately at a Trench wall cutter also determined via the depth position of the device because the external pressure is proportional to the depth of the Device is within a liquid.
  • a Trench wall cutter also determined via the depth position of the device because the external pressure is proportional to the depth of the Device is within a liquid.
  • Sensors such as the winch, can control the location of the ambient pressure be determined, so even without an external pressure sensor a pressure adjustment is possible.
  • Another advantage of the invention is that the internal pressure so controlled and / or regulated in the gearbox that he is equal or about a defined pressure difference is less than or greater than the measured external pressure.
  • About the Control device can therefore always have a defined overpressure or negative pressure in the gearbox. At a given overpressure will ensure that no Liquid from the outside can penetrate into the gear housing.
