A crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, wherein a movement simulation module is provided for determining movements and/or deformations of the machine components according to the inputted control commands, depending on which the graphical simulation module calculates the virtual representation. Proposed is a data emulation using hardware components, which carry out actual actuating movements and thus simulate 'actual' actuating movements of the machine to be simulated, in order to provide corresponding movement data more rapidly and with less computing performance, whereby a more realistic simulation can be achieved in real-time or almost real-time.

Crane, construction machine or industrial truck simulator

A simulator for a crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, a movement simulation module being provided for determining movements and/or deformations of the machine components according to the inputted control commands, according to which the graphical simulation module calculates the virtual representation. The control station is movably mounted and can be moved by a drive device according to the movements and/or deformation of the machine components determined by the movement simulation module. The virtual representation generated by the graphical simulation module can be superimposed with a live image provided by a camera and displayed on virtual reality glasses.

Simulator for crane, construction machine or industrial truck

A bearing bush of a turbocharger for radially mounting a shaft of the turbocharger. The bearing bush on an inner surface facing the shaft to be mounted, which forms a running surface of the bearing bush, has a microstructuring of multiple cup-shaped recesses at least in sections. The recesses have a maximum depth.

Bearing bush of a turbocharger and turbocharger

The invention relates to a simulator for a crane, a construction machine or an industrial truck, provided with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, a movement simulation module being provided for determining movements and/or deformations of the machine components according to the inputted control commands, according to which the graphical simulation module calculates the virtual representation. According to the invention, the control station is movably mounted and can be moved by a drive device according to the movements and/or deformation of the machine components determined by the movement simulation module.

A turbocharger, including a turbine with a turbine rotor, a compressor with a compressor rotor coupled to the turbine rotor via a shaft. At least one bearing, via which the shaft is mounted in the bearing housing, wherein the respective bearing comprises a bearing bush mounted in the bearing housing in a rotationally fixed manner, wherein between the bearing bush and the bearing housing a radially outer lubricating gap and between the bearing bush and the shaft a radially inner lubricating gap is formed. The radially inner lubricating gap is suppliable with lubricating oil via at least one line introduced into the bearing bush, wherein the or each line introduced into the bearing bush, which serves for the oil supply of the radially inner lubricating gap, leads into a lubricating oil pocket of the bearing bush each, which based on the axial length of the bearing bush is placed off-center.

Turbocharger

A turbocharger, with a turbine a turbine housing and a turbine rotor, with a compressor with a compressor housing and a compressor rotor that is coupled to the turbine rotor via a shaft, with a bearing housing arranged between the turbine housing and the compressor housing, wherein both the turbine housing and also the compressor housing are connected to the bearing housing, with at least one bearing, via which the shaft is mounted in the bearing housing, wherein the respective bearing comprises a bearing bush arranged in the bearing housing, wherein between the bearing bush and the bearing housing a radially outer lubricating gap and between the bearing bush and the shaft a radially inner lubricating gap are formed, wherein the radially outer lubricating gap and the radially inner lubricating gap are suppliable with lubricating oil emanating from an oil supply main line independently of one another.
