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

Embodiment 1

[0037] Such as figure 1 and figure 2 As shown, the ring-shaped buffer device used on the coupler buffer in this embodiment includes a buffer element 1 and an end beam connecting block 2. The end beam connecting block 2 is provided with a buffer element 1 for placing and matching with the buffer element 1 in size. The placement hole 21 is provided with a step 211 on the inner wall of the lower end of the placement hole 21, and the middle part of the buffer element 1 is provided with a mounting hole 11 for connecting and fixing with the coupler. The buffer element 1 includes a cylindrical inner core 12 and surrounding inner core 12. The buffer structure 13 is provided, and the buffer structure 13 is composed of several buffer units 131 .

[0038] In this embodiment, the buffer unit 131 is composed of three metal partitions 1311 of an integral ring structure and three elastic bodies 1312 of an integral ring structure arranged in crosswise arrangement.

[0039] In this embodime...

Embodiment 2

[0041] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, there are two buffer units 131, and each buffer unit consists of three semicircular metal partitions 1311 and three semicircular structures. The elastic body 1312 is arranged in a circular ring structure, and the metal partition 1311 and the elastic body 1312 are connected by a separate connection. The outermost layer of the structure formed by the metal partition 1311 and the elastic body 1312 is provided with a metal jacket 4, all the other are with embodiment 1.

Embodiment 3

[0043] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the buffer unit 131 is composed of three monomers, and each monomer is composed of an arc-shaped metal partition 1311 and an annular elastic body The monomer composition that 1312 forms, all the other are with embodiment 1.

Abstract

The invention discloses an annular buffer device used for coupler buffers. The annular buffer device includes a buffer element and an end beam connecting block; the end beam connecting block is provided with a placing hole used for placing the buffer element and matching the size of the buffer element; the lower end of the placing hole is provided with a step; the middle part of the buffer elementis provided with an installation hole used for fixedly connecting to a vehicle coupler; the buffer element includes a cylindrical inner core and buffering structures arranged around the periphery ofthe inner core; and the buffering structures consist of multiple buffering units. The buffer device is simple in structure, convenient in installation and maintenance, high in installation and maintenance efficiency, short in length and light in mass on the basis of guaranteeing a certain compression stroke, maximum acting force, buffering capacity and energy absorption rates, so that lightweightdevelopment of whole coupler buffers can be realized; and the buffer device can effectively reduce wheelset transverse force, so that accidents of the derailment and rollover of trucks can be avoided,and therefore, high operation safety can be achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an annular buffer device used on a coupler buffer. Background technique [0002] The coupler buffer is one of the important devices on the rail vehicle. Its main function is to connect the front and the carriage or the carriage and the carriage to alleviate the change of the traction force or the connection between starting, braking and shunting during the operation of the train. Longitudinal impact and vibration caused by vehicles colliding with each other when the vehicle is hanging, and wheel set lateral force when the vehicle is turning, so as to reduce the damage to the structure of the vehicle body and improve the stability and comfort of the 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 b...
