Problems solved by technology

It can be seen that the dimensional chain between the car body and the frame includes the air spring airbag 16. Since the airbag 16 is a rubber part, the elastic deformation is relatively large, and it cannot undertake the overall lifting function of the bogie.

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0028] A frame with integral lifting functions, such as image 3 , consists of a secondary suspension device 1 and a frame (frame side beam 2 and frame beam 3).

[0029] Such as Figure 4 As shown, the framework of the present invention cancels the four lifting seats on the frame beam, because the traction seat no longer needs to bear the lifting function, and does not need to be used in conjunction with the frame lifting seats, and its size can be redu...

Abstract

The invention discloses a secondary suspension device and framework. The secondary suspension device comprises an air spring and is characterized in that a support rod is mounted on the lower portionof the bag body of the air spring, and an upper cover plate is mounted at the top of the bag body of the air spring; a hoisting plate with a central hole is mounted between the upper cover plate and the bag body fastening ring of the air spring; the lower portion of the support rod is provided with a hoisting pin mounting hole or a hoisting pin is fixedly mounted on the lower portion of the support rod; the top of the support rod is provided with a hole allowing a hoisting rod to penetrate; the top of the support rod penetrates the bag body and extends into the central hole of the hoisting plate, and the hoisting plate is radially provided with at least one hoisting rod mounting hole serving as the mounting channel of the hoisting rod during framework hoisting. The secondary suspension device can serve as a framework having a hoisting function.

Description

technical field [0001] The invention relates to a secondary suspension device and a frame, belonging to the technical field of rail transit vehicle equipment. Background technique [0002] With the high-speed and rapid development of rail transit vehicles, the product types of bogies are becoming more and more diverse. In order to meet the requirements of various types of bogies, the arrangement of equipment on the bogies also faces various challenges, especially for high-speed large-axle load bogies. The high structural strength requirements of various types of equipment lead to large equipment sizes and occupy a lot of space. At the same time, as the train safety requirements are getting higher and higher, it is necessary to add a variety of monitoring equipment, and the requirements for bogie equipment layout are further improved. [0003] The overall hoisting function of the existing bogies is realized through the cooperation of the traction device (equipped with liftin...
