Control for the joint of four-axled rail vehicles, in particular trams

摘要

The invention relates to a control for the joint of four-axled rail vehicles, in which the two carriage bodies (2, 2a) are mounted on one bogie (13b, 13a) in each case and are connected in their centre by means of a joint (12). Since this joint (12) requires a control so as not to migrate inadmissibly when going round bends, it is proposed according to the invention that the secondary springs be constructed as solid-rubber or flexicoil springs since the latter exert a torque on the carriage body (2a) via the front bogie (13a), whilst by means of the secondary springs of the following bogie (13b), restoring moments are exerted on the wagon body (2), so that the position of the joint (12) is automatically set in the desired manner due to balancing of the moments when the tension in the secondary springs is released. <IMAGE>
