Problems solved by technology

[0004] The patent No. 200680000406.3 discloses a central buffer coupling for rail vehicles. The impact protection device is provided on this buffer coupling, but the impact protection device is arranged on the hinge device, and the support seat of the hinge device is connected with The carriage is connected, that is, when the impact protection is damaged, the impact protection will fall off on the carriage together with the hinge
On the other hand, the buffer device is usually provided with a vertical support device to vertically support the buffer. However, due to the unreasonable structure of the vertical support device, when the buffer device falls off, the vertical support device usually falls off with the buffer. fall or fall out

Embodiment 1

[0027] as attached figure 1 , attached figure 2 and attached image 3 Shown:

[0028] An internal shearing buffer device, comprising a buffer body connected to the coupler, a mounting seat 1 connected to the vehicle body, the internal shearing buffering device also includes an intermediate bearing seat 2 connected to the buffer body, and the mounting seat 1 It is connected with the middle bearing seat 2 through the rotating shaft 3, and the installation method of the bearing seat 2 and the mounting base 1 is that the bearing base 2 is installed inside the mounting base 1 through the rotating shaft 3; the buffer body includes a buffer housing 5 and a buffer rod 4. The inside of the buffer housing 5 is provided with a rubber block 8 covering the buffer rod 4, and the buffer rod 4 extends to the front end of the buffer housing 5; the front end of the intermediate bearing seat 2 is provided with an overload protection device 6, and the buffer The shell 5 is connected to the in...

Embodiment 2

[0033] as attached Image 6 , attached Figure 7 and attached Figure 8 Shown:

[0034] The difference from Embodiment 1 is that the mounting base 1 and the intermediate bearing base 2 are connected through the rotating shaft 3 , but the mounting base 1 and the bearing base 2 are installed in such a way that the bearing base 2 is installed outside the mounting base 1 through the rotating shaft 3 . Both the installation methods of the bearing seat 2 and the installation seat 1 in Embodiment 1 and Embodiment 2 can ensure the stable operation of the buffer device.

[0035] attached Figure 9 And attached Figure 10 A schematic diagram of the working state structure of the specific embodiment 2 of the present invention is given, and the working principle of this embodiment is the same as that of the embodiment 1.

Abstract

The invention discloses an inner shearing buffer device. The device comprises a buffer main body connected with a car coupler, and a mounting base connected with a car body. The device is characterized by further comprising a middle bearing base connected with the buffer main body, wherein the mounting base and the middle bearing base are connected through a rotating shaft; the buffer main body comprises a buffer shell and a buffer pull rod; a rubber block for coating the buffer pull rod is arranged in the buffer shell; the buffer pull rod extends to the front end of the buffer shell; the front end of the middle bearing base is provided with an overload protecting device; the buffer shell and the middle bearing base are connected through the overload protecting device; the front end of the middle bearing base is additionally provided with a vertical rubber support; the vertical rubber support is arranged at the lower end of the buffer pull rod for supporting the buffer pull rod. As the overload protecting device of the buffer is mounted at the front end, the buffer is released from the back end when the overload exceeds the design value of the overload protecting device.

Description

technical field [0001] The invention relates to a railway vehicle buffer device, in particular to a rail vehicle coupler internal shear buffer device. Background technique [0002] The coupler buffer device is generally composed of a coupler head, a buffer, and a shearing device. It is one of the basic components of a rail vehicle. Its main function is to transmit traction, braking force, and moderate longitudinal impact after the vehicle is connected. [0003] The buffer is a part of the coupler buffer device. The main function of the buffer is to alleviate the longitudinal impact of the train during operation and improve the stability and comfort of the train. The buffer in the coupler buffer device is installed in the mounting seat, and is usually connected to the car body through the mounting seat. Its working principle is to use the elastic parts in the buffer to buffer the impact force during traction or stretching. When the impact load is greater than that of the buff...
