A soil processing machine, in particular a soil compactor, comprising at least one battery () supported on a machine frame () and at least one consumer of electrical energy () fed from the at least one battery (), further comprising at least one interchangeable charging module () which is detachably supported on the machine frame (), has a battery connection region () for connecting the at least one interchangeable charging module () to a battery management system (), and has a voltage supply connection region () for connecting the at least one interchangeable charging module () to an external voltage source.

Soil processing machine

A soil processing machine, in particular a soil compactor, comprises a machine frame and a casing () carried on the machine frame and/or at least partially providing it and bounding a unit receptacle space (), wherein the casing () has a cooling air inlet area () and a cooling air outlet area () for cooling air flowing through the unit receptacle space (), wherein a plurality of units around which cooling air can flow through the unit receptacle space () from the cooling air inlet area () to the cooling air outlet area () are arranged in the unit receptacle space (), wherein at least two of the units arranged in the unit receptacle space () have maximum permissible operating temperatures different from one another and at least one unit having higher maximum permissible operating temperature is arranged upstream in a cooling air flow direction from the cooling air inlet area () to the cooling air outlet area () with respect to at least one unit having lower maximum permissible operating temperature.

A soil processing machine, in particular a soil compactor, includes at least one drive roller and an electrohydraulic drive system for driving at least one drive roller. The drive system has a traction hydraulic circuit having at least one hydraulic motor and at least one hydraulic pump. The circuit includes a first line region between a first connection fitting of the at least one hydraulic pump and a first connection fitting of each hydraulic motor to drive the at least one drive roller in a first rotatable direction and a second line region between a second connection fitting of the at least one hydraulic pump and a second connection fitting of each hydraulic motor to drive the at least one drive roller in a second, opposite rotatable direction. A valve assembly is provided with each line region for selectively interrupting and releasing a fluid flow connection between the at least one hydraulic pump and at least one hydraulic motor.

Soil processing machine and method for operating a soil processing machine

A construction machine comprises: a system region that can be rotated about an axis of rotation relative to a machine frame; at least one electrical load () in the rotatable system region; and an induction energy-transfer assembly () for wirelessly transferring energy into the rotatable system region, the induction energy-transfer assembly () comprising a transmitting assembly () having at least one transmitting coil () and, in the rotatable system region, a receiving assembly () having at least one receiving coil ().
