Definitions
- the present invention relates to a method for closing bridging couplings in a load-slide transmission of a work machine according to the preamble of patent claim 1.
- an open converter lock-up clutch is actuated in the closing direction when the turbine speed exceeds a threshold value at which the turbine torque is equal when the lockup clutch is closed and the lockup clutch is open.
- a closed lockup clutch is actuated in the opening direction when the turbine speed falls below a threshold value at which the turbine torque is the same when the lockup clutch is open and open.
- the present invention has for its object to provide a method for closing the Wandlerüberbrückungskuppiu ⁇ g in a powershift transmission of a work machine, by its implementation, the shift quality of the circuits of the lockup clutch, especially in the partial load range is improved.
- the acceleration and thus the acceleration shock when switching the WandlerüberbrückungskuppSung should be largely reduced or avoided. Further embodiments and advantages of the invention will become apparent from the dependent claims.
- the snubber clutch is passed through an engine guide during the closing process by increasing the engine torque, i. the gradient of
- wsra before a: clutch determines the upcoming engine or Turbine ⁇ mome ⁇ t, wherein depending on the determined engine or turbine torque of the gradient of the engine torque during the circuit and optionally a defined time after the circuit via the transmission control is performed such that an acceleration of the vehicle and thus an acceleration shock when switching is reduced or avoided.
- the turbine torque is determined via the converter characteristic applied in transmission control.
- the guidance takes place in dependence on the circuit of the torque or turbine torque on the basis of an in
- the gradient of the engine torque can, according to, a development of
- the second characteristic agrees with the first characteristic or that the first characteristic is used to guide the gradient of the engine torque after the circuit.
