RAILWAY VEHICLE AND ASSOCIATED TRAFFIC METHOD
First Claim
1. A railway vehicle comprising at least one car and at least one bogie carrying the car, the bogie comprising a chassis and a secondary suspension system between the chassis and the car, the secondary suspension system, comprising:
- a jack comprising two ends extending along a same axis; and
a power supply system of the jack;
wherein the jack is fluidly connected to the power supply device (38) by at least one flow limiter, andwherein the jack is configured to go from a first so-called passive configuration, in which the supply device is inactive, the jack then being able to passively damp the oscillations in an elevation direction between the car and the chassis using the flow limiter, to a second so-called active configuration in which the supply device is configured to supply the jack in order to modify the distance between the car and the chassis or in order to keep the distance constant between the car and the chassis.

Abstract
Disclosed is a railway vehicle with a car and a bogie. The bogie includes a chassis and a secondary suspension system. The secondary suspension system includes a jack and a power supply device of the jack fluidly connected to the jack by at least one flow limiter. The jack is configured to go from a first so-called passive configuration, in which the supply device is inactive, the jack then being able to passively damp the oscillations between the car and the chassis using the flow limiter, to a second so-called active configuration in which the supply device is configured to supply the jack in order to modify the distance between the car and the chassis or in order to keep the distance constant between the car and the chassis.
