Abstract
A railway vehicle having a variable trim body, comprising two bogies with respective frameworks and swinging transverse members, articulated connection levers between each swinging transverse member and the body, and a body roll control system to perform, while the vehicle is running along a curve, rotations of the body around a longitudinal axis so as to limit the non-compensated centrifugal acceleration acting on the body. The control system employs linear double-effect actuators acting on the articulated connection levers, whereby the body rotations are operated by virtue of the rotations of these levers.
Claims5
A railway vehicle comprising a variable trim body having a longitudinal axis, two bogies having respective frameworks and swinging transverse members, articulated connection levers between each of said swinging transverse members and said body, and a body roll control system including actuator means operable to perform, while the vehicle is running along a curve, rotations of said body about said longitudinal axis tending to limit non-compensated centrifugal acceleration acting on said body, wherein said actuator means direct act on said articulated connection levers, whereby said body rotations are operated by virtue of rotations of said levers.
