Abstract
A towing arrangement intended for train couplers includes a bar (8), which at a rear end has an axially projecting pin (10), which projects through a through hole (40) in a plate (11), which on both sides is surrounded by shock-absorbing spring members (12), which always aim to hold the pin in a starting position in relation to the plate, and against the action of which the pin together with the bar are axially movable. The plate (11) is included in a mandrel (16) equipped with a cone (19), which mandrel is inserted into a deformation tube (17), more precisely into a wide, front tube section (22), which via a waist (23) transforms into a thinner, rear tube section (21), which is deformable by the mandrel (16). A deformation tube is also described.

Towing arrangement for train coupler, comprising a bar (8), which at a rear end includes an axially projecting pin (10), which projects through a through hole (40) in a plate (11), which on both sides is surrounded by shock-absorbing spring members (12), which always aim to hold the pin in a starting position in relation to the plate, and against the action of which the pin together with the bar are axially movable, characterized in that said plate (11) is included in a mandrel (16) equipped with a cone (19), which mandrel is inserted into a deformation tube (17), more precisely into a wide, front tube section (22), which via a waist (23) transforms into a thinner, rear tube section (21), which is deformable by the penetration of the mandrel.
Deformation tube for towing arrangement for train coupler, characterized in that the same has a cylindrical basic shape and comprises a rear section (21), which via a conically widening waist (23) transforms into a wider front section (22), to which a flange (25) is united for the fixation of the deformation tube in a frame or chassis of a vehicle unit, and that internally in the wide, front section, there is means (31) in order to secure a clamp ring (32).
