The present disclosure relates to a spring system comprising a strut for arrangement between a dolly and a body of a rail vehicle with a cylinder and a piston displaceably received in the cylinder which bound a piston chamber, with the piston or the cylinder being connectable to the dolly and the other of the components being connectable to the body and with one or more springs which cushion the body with respect to the dolly, with a non-resilient hydraulic system which is in communication with the piston chamber and by means of which the amount of the hydraulic medium in the piston chamber can be varied for the purpose of adjusting the strut length, with an abutment member being provided by means of which the end position of the piston can be changed in the cylinder and with means being provided which are made such that they actuate the abutment member when the piston chamber or the hydraulic system is pressure-less or the pressure in the piston chamber or in the hydraulic system falls below a value.
A spring system comprising a strut for arrangement between a dolly and a body of a rail vehicle with a cylinder and a piston displaceably received in the cylinder which bound a piston chamber, with the piston or the cylinder being connectable to the dolly and the other of the components being connectable to the body and with one or more springs which cushion the body with respect to the dolly, with a non-resilient hydraulic system which is in communication with the piston chamber, the hydraulic system for varying an amount of a hydraulic medium in the piston chamber for adjusting the strut length, with an abutment member to change an end position of the piston in the cylinder and with means for actuating the abutment member when the piston chamber or the hydraulic system is pressure-less or the pressure in the piston chamber or in the hydraulic system falls below a value.
A method for controlling ride height of a rail vehicle, the vehicle having a spring system having a strut for arrangement between a dolly and a body of the rail vehicle with a cylinder and a piston displaceably received in the cylinder which bound a piston chamber, with the piston or the cylinder being connectable to the dolly and the other of the components being connectable to the body and with one or more springs, with a non-resilient hydraulic system which is in communication with the piston chamber, the method comprising:
A strut for arrangement between a dolly and a body of a rail vehicle, the strut having a cylinder, with a piston displaceably received in the cylinder, wherein the cylinder and the piston bound a piston chamber, with the piston or the cylinder being connectable to the dolly and the other of the components being connectable to the body, and with one or more springs which cushion the body with respect to the dolly, and an abutment member, the strut comprising:
