Chassis for a rail vehicle
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.
