Active corner driving device and rotary car coupler

Abstract

The invention provides an active corner driving device and a rotary car coupler. The device comprises a centering mechanism, the centering mechanism comprises a shell assembly, a centering disc and a piston assembly, the centering disc is arranged in the shell assembly in a pivoted mode, the piston assembly abuts against the circumferential wall of the centering disc, a sleeve, a protrusion, a notch and a cam are arranged on the centering disc, and the protrusion and the notch are symmetrically arranged on the two sides of the cam; the guide plate assembly is connected with the shell assembly and the sleeve and provided with an arc-shaped guide groove matched with the cam and the protrusion, and the protrusion is arranged in the arc-shaped guide groove; the driving mechanism is pivotally mounted in the shell assembly and comprises a cam plate assembly provided with a strip-shaped groove and a driving shaft assembly mounted in the strip-shaped groove; and the power assembly is connected with the driving mechanism. The power assembly pushes the cam plate assembly to rotate and extrude the piston assembly, the driving shaft assembly moves along the guide groove, and when the driving shaft assembly moves to make contact with the protrusion, the driving shaft assembly continues to move to push the centering disc to rotate. The centering disc is connected with a mechanical structure, and automatic rotation of the mechanical structure can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rail train coupler buffer devices, and in particular relates to an active angle driving device and a rotating coupler. Background technique [0002] Generally, the couplers of trams and subway projects are equipped with centering devices that cannot be rotated automatically, and the automatic horizontal swing of the couplers cannot be realized. There is a disclosed coupler rotating mechanism in the prior art, which can realize the function of rotating the coupler at any angle in the horizontal direction. When the coupler needs to swing horizontally, the air intake of the cylinder is first cut off, and the return spring of the cylinder moves the tappet of the cylinder backward, and simultaneously drives the roller and the arc notch of the internal gear cam disc to separate, and the internal gear cam disc is in a free state. At this time, the external gear transmission mechanism is driven to rotate by a bi...
