Problems solved by technology

Since the existing tie rod seat and the side beam of the car body chassis are welded together and become a part of the car body composition, after a serious collision accident occurs on a train running on the line, the tie rod seat will have a rigid collision with the connecting rod of the bogie, and the collision When the energy is too large, the tie rod seat will be deformed or even broken, which will cause the side beam of the car body to be twisted and deformed, which will affect the safety of the whole vehicle and cause difficult maintenance problems in the later stage

Embodiment 1

[0035] The embodiment of this application provides a tie rod seat 3, please refer to figure 1 and figure 2 , the rod seat 3 is a split structure, and includes a base 31 and a connecting seat 32; the base 31 is used for fixed connection with the vehicle body 1; the top of the connecting seat 32 is detachably connected to the bottom of the base 31, and the connecting seat 32 is provided with a connecting structure for installing the bogie 2 . Such as figure 1 and figure 2 As shown in the structure, the rod base 3 with a split structure is adopted. The rod base 3 includes a base 31 and a connecting base 32 that are detachably connected together. The top of the base 31 is used to be fixedly connected to the vehicle body 1, such as image 3 The side beam 11 of the bottom frame of the car body 1 shown in the structure; the bottom of the base 31 is used to be fixedly connected with the top of the connecting seat 32 through fasteners and other connection methods, and the connecti...

Embodiment 2

[0046] The embodiment of the present application also provides a car body 1, such as image 3 and Figure 4 As shown in the structure, the vehicle body 1 includes a side beam 11 , and also includes any tie rod seat 3 as provided in the above embodiments, and the base 31 of the tie rod seat 3 is fixedly connected to the side beam 11 . The car body 1 can be an end chassis part, and the side beam 11 bottom of the end chassis is equipped with a tie rod seat 3, such as Figure 5 , Figure 6 and Figure 7 As shown in the structure, the tie rod seat 3 can be welded to the side beam 11 through the top surface of the base 31, so that the base 31 and the side beam 11 form an integrated structure, the bogie 2 is installed on the bottom of the vehicle body 1, and the tie rod 21 and the frame The body 22 is installed on the tie rod seat 3 to realize the installation of the bogie 2.

Embodiment 3

[0048] The embodiment of the present application also provides a rail vehicle. The rail vehicle includes a bogie 2 and a car body 1 as provided in the above embodiment. The tie rod 21 of the bogie 2 is fixedly connected to the connecting structure of the connecting seat 32, and the steering The frame body 22 of the frame 2 is movably connected to the connection structure; as Figure 7 As shown in the structure, the bogie 2 is installed on the bottom of the car body 1. The bogie 2 includes a tie rod 21 and a frame body 22. One end of the tie rod 21 is fixedly connected to the connecting seat 32 of the tie rod seat 3 through a bolt 331 and a nut 332. The frame body 22 One end of one end is movably connected with the connection base 32 through a pin shaft passing through the oblong hole 323 , and the pin shaft can slide up and down in the oblong hole 323 .

Description

technical field [0001] The present application relates to rail vehicle technology, in particular, to a tie rod seat, a car body and a rail vehicle. Background technique [0002] In recent years, with the rapid development of my country's high-speed rail technology, it has been recognized worldwide. Orders for railway passenger cars exported to the United States, Canada and other countries have increased year by year. The United States, Canada and other countries generally require railway passenger cars to use their own bogies, because the bogie structures in the United States, Canada and other countries are different from those in my country, and the interface between the bogie and the car body is arranged on both sides of the car body. On the side, it is different from the bogie interface structure of the existing car body in my country. Therefore, when exporting rail cars to the United States, Canada and other countries, it is necessary to set tie rod seats that match thei...
