Abstract: A chassis for a rail vehicle includes a chassis frame supported on at least first and second wheelsets and one A-frame linkage per wheelset on both sides of the chassis for horizontal axle guidance of the wheelset. Each A-frame linkage is connected in an articulated manner to one of two axle bearings of a wheelset by a wheelset-side bearing and to the chassis frame by two frame-side bearings. At least one of the bearings per A-frame linkage has a hydraulic bushing with variable longitudinal rigidity. The hydraulic bushing has at least one fluid chamber fillable with hydraulic fluid so that in the fluid chamber a hydraulic pressure can form for adjusting longitudinal rigidity. An acceleration sensor per axle bearing measures wheelset acceleration and an adjustment device adjusts hydraulic pressure in at least one of the fluid chambers depending on the measured wheelset acceleration.

Additionally, the simulation component includes a simulation module which is configured to (i) perform a simulation of the medical image scanner using the modified scanner configuration dataset to yield simulated results, (ii) use the display module to present the simulated results in the GUI, and (iii) in response to receiving user approval of the simulated results via the GUI, save the modified scanner configuration dataset to the database.

Abstract: A chassis for a rail vehicle, in particular for a locomotive. A chassis frame is supported on first and second wheel sets and one triangular link per wheel set on both sides of the chassis for horizontally guiding the axle of the wheel set. An A-arm is hinged to one of two axle bearings by a wheel set-side bearing and by two frame-side bearings. The latter have elastomer bushings with a constant longitudinal and transverse rigidity. The former have hydraulic bushings with constant transverse rigidity and variable longitudinal rigidity. The bearings of each A-arm are arranged on the corners of a horizontal isosceles triangle. The tip of the triangle forms the wheel set-side bearing and the base forms the frame-side bearings. This resolves the conflicting objectives between dynamic running behaviors of the chassis when cornering and the driving stability when traveling straight ahead at a high speed.
