Split type buffering mechanism used for coupler buffers

Abstract

The invention discloses a split type buffering mechanism used for coupler buffers. The buffering mechanism includes a middle inner core and two buffering units symmetrically arranged along the inner core; the two buffering units are spliced on the two sides of the inner core by adopting a split type, and are not in contact with each other; the inner core is a circular ring structure, and the middle circular ring structure can be taken as an installation hole for connecting the buffering mechanism and a vehicle coupler; and the buffering units consist of multiple arc-shaped metal separating plate and multiple elastomers with arc-shaped structures through cross arrangement. The buffering mechanism is simple in structure, convenient in installation and maintenance and high in installation andmaintenance efficiency on the basis of guaranteeing a certain compression stroke, maximum acting force, buffering capacity and energy absorption rates, so that lightweight development of whole coupler buffers can be realized; and the buffering mechanism can effectively reduce wheelset transverse force, so that accidents of the derailment and rollover of trucks can be avoided, and therefore, highoperation safety can be achieved.

Description

technical field [0001] The invention relates to a buffer mechanism, in particular to a split type buffer mechanism used on a coupler buffer. Background technique [0002] The coupler is one of the important devices on the rail vehicle. Its main function is to connect the front and the car or the car and the car to ease the change of the traction force during the operation of the train or when starting, braking and shunting. Longitudinal impact and vibration caused by mutual collision of vehicles, and wheel set lateral force when vehicles turn, so as to reduce the damage to the structure of the vehicle body and improve the stability and comfort of train operation. The existing coupler buffer is divided into a group of N buffer elements, which are responsible for the compression when the vehicle starts and the compression when the vehicle decelerates. This kind of coupler buffer is not only complicated in structure, but also has a long and heavy structure, which is troublesome...

Problems solved by technology

The existing coupler buffer is divided into a group of N buffer elements, which are responsible for the compression when the vehicle starts and the compression when the vehicle decelerates. This kind of coupler buffer is not only complicated in structure, but also has a long and heavy structure, which is troublesome and time-consuming to repair and replace. Long, resulting in low installation and maintenance efficiency

[0003] In addition, for the current port truck track and other workplaces where the radius of the curved line is very small (about R50m) and there are many curves, the existing coupler buffer device structure is too long and too heavy, and the existing coupler buffer element structure cannot meet the requirements. The driving requirements with a small curve radius are likely to generate a large wheel set lateral force, resulting in derailment and rollover accidents of the truck
