Compact centring device

Abstract

The invention relates to a compact centring device installed on a compact buffer. The centring device comprises a centring sleeve, a centring body, a roller, a roller plug and a spindle, wherein the centring sleeve is installed on an installation seat of the buffer and is connected with the roller plug by fastening; the centring body and the spindle are fastened on a buffer system of the buffer; a centring element is installed in the centring body and synchronously rotates with a revolving axle of a revolving mechanism of the buffer. The centring device has simple and reasonable structure. The centring element is arranged inside the centring body, therefore, the centring device is small in volume and convenient to install. Under the action of the roller, after a hook buffer device rotatesin the horizontal direction in the presence of external force, the buffer device can restore to the initial state when the external force disappears or diminishes, thus ensuring the centre line of the hook buffer device to be identical with the centre line of the vehicle. The hook buffer device can not further rotate through contact of the limiting surface between the centring sleeve and the centring body, thus preventing accidents due to too large rotation angle.

Description

technical field [0001] The invention relates to a buffer device for railway vehicles, in particular to a compact buffer for railway vehicles. Background technique [0002] The compact buffer generally includes a buffer system, a rubber support, a centering device and a mounting seat, in which the buffer system can absorb the longitudinal impact of the vehicle during operation, and can effectively improve the comfort of the vehicle during operation; the rubber support The function is to support the hook and buffer device in the vertical direction; the centering device can automatically restore the centering after the hook and buffer device rotates in the horizontal direction, so that the center line of the hook and buffer device is consistent with the center line of the vehicle; the installation seat can Mount the entire shock absorber securely on the vehicle underframe. However, in the existing centering device, since the centering element is arranged outside the centering ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned problems of existing compact buffers such as poor automatic recovery performance after rotation in the horizontal direction and excessive volume, and to provide a buffer device with a simple and reasonable structure, small volume, and automatic recovery after rotation of the buffer device. High performance compact centering device
