Abstract: The invention relates to a method for producing a hardened steel component with a coating composed of zinc or a zinc alloy; a blank is stamped out of a sheet coated with the zinc or zinc alloy, the stamped-out blank is heated to a temperature ?Ac3 and if need be, kept at this temperature for a predetermined time in order to induce the formation of austenite, and then the heated blank is transferred to a forming die, is formed in the forming die, and is cooled at a speed that is greater than the critical hardening speed and thus hardened; the steel material is adjusted in a transformation-delaying fashion so that a quench hardening through transformation of austenite into martensite takes place at a forming temperature that lies in the range from 450° C. to 700° C.; after the heating and before the forming, an active cooling takes place at >15K/s.

Abstract: A method of actuating a clutch of a hydrodynamic torque converter in a self-propelling working machine such that when the clutch is engaged and thereby connects a drive input of the hydrodynamic torque converter to a drive output of the hydrodynamic torque converter, and when a service brake is actuated, the clutch is disengaged thereby separating a drive input of the hydrodynamic torque converter from a drive output of the hydrodynamic torque converter. The method comprises the steps of, when the service brake is actuated, actuating the clutch in the engaging direction, and maintaining engagement of the clutch if a device for recognizing a driving status of the working machine detects that the working machine is driving downhill.

Abstract: A method of operating the torque converter lock-up clutch in a power transmission of a working machine comprising at least one hydraulically actuated lifting device.

Abstract: During reversal of drive of a vehicle, particularly a work machine with a hydrodynamic torque converter and a bypass clutch, the bypass clutch is first disengaged, during the reversal process. Next, a previously engaged first driving direction clutch, driving the vehicle in the first driving direction, is disengaged and a second driving direction clutch, for driving the vehicle in the second driving direction, is engaged so that a speed of the vehicle, in the first driving direction, is reduced and a speed of the vehicle, in the second driving direction, is subsequently accelerated, whereby the drive motor is operated at a higher rotational speed during the reversal process.

Abstract: The invention relates to a method for the production of a hardened component made of a hardenable steel, wherein the steel strip is exposed to a temperature increase in an oven, and is thus exposed to an oxidizing treatment such that a surface oxide layer is created, and subsequently a coating using a metal or a metal alloy is carried out. The strip is heated and at least partially austenitized for producing an at least partially hardened component, and subsequently cooled and thereby hardened. The invention also relates to a steel strip produced according to said method.
