Mechanical coupling in a draftgear

摘要

A mechanical coupling, particularly in a draftgear in rail vehicles, includes a central plate (5) turnably mounted in a coupler head and having a link (7) pivoted in the same, and including a hooking mechanism for detachable hooking up of the central plate and the link in the non coupled position of the coupling, and a releasing device (10) for the automatic detachment of the hooking mechanism upon coupling. The hooking mechanism includes a hooking rod (12) pivotally connected with the central plate, which rod, by a lug (16), clutches a collar (11) arranged in the coupler head and, upon activation of the releasing device, detaches from the collar. A leaf spring (13) is arranged in the coupler head in order to, in abutment against the hooking rod, force the same, under the bias from the spring, to be pressed against the collar in the hooked up and disengaged positions.

1. Mechanical coupling usable in a draftgear in rail vehicles, comprising:
a coupler head (1); a collar (11) arranged in the coupler head (1); a central plate (5) turnably mounted in the coupler head; a coupling link (7) pivoted in the central plate (5); a hooking mechanism for detachable hooking up of the central plate and the coupling link in a non-coupled position, the hooking mechanism including i) a releasing device (10) for automatic detachment of the hooking mechanism upon coupling, ii) a hooking rod (12) pivotally connected with the central plate, the hooking rod having a lug (16), wherein the hooking rod, by the lug (16), clutches the collar (11) arranged in the coupler head and, upon activation of the releasing device, is detached from said collar; and a leaf spring (13, 13′, 13″) arranged in the coupler head in abutment against the hooking rod (12), wherein the hooking rod, under bias from the leaf spring (13, 13′, 13″), is pressed against the collar (11) in a hooked up position and in a detached position.
