Title:
CAR-COUPLER BUFFER AND RAILWAY CAR
Document Type and Number:
WIPO Patent Application WO/2015/058662
Kind Code:
A1
Abstract:
A car-coupler buffer comprising: a coupler yoke used for connecting to a car coupler; a front base body used for being mounted onto a car body; a first flexible element abutted against the coupler yoke at the rear extremity and abutted against the front base body at the front extremity, when the car body is subjected to a traction force, the first flexible element is compressed by the force; a housing arranged at the rear extremity of the coupler yoke, where the rear extremity of the housing is used for connecting to the car body, the housing and the coupler yoke are connected in series via a connecting shaft, and the coupler yoke is allowed to move in the axial direction of the connecting shaft; and, a second flexible element arranged between the housing and the coupler yoke, when the car body is subjected to a compression force, the second flexible element is compressed by the force. With such arrangement, the car-coupler buffer provided in the present invention provides a bidirectional buffer property, and, regardless of whether the car body is subjected to an effect of a traction force or an effect of a compression force, the car-coupler buffer provides an improved buffering effect, thus preventing the problem of exacerbated fatigue damages resulting from a rigid load being withstood directly by a coupler body, a coupler tongue, and the coupler yoke. A railway car having the car-coupler buffer.
