Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the anti-rolling torsion rod seat involved in the method embodiment of the present invention is composed of a first web 1, a second web 2, and an anti-rolling torsion rod mounting block 3. The bottom center of the anti-rolling torsion rod mounting block 3 There are notches, and two sides of the notches are provided with mounting holes for the anti-side-rolling torsion bar; the installation method includes the following steps:

[0020] In the first step, a hole through which the first web 1 passes is opened on the lower cover plate 5 of the corbel;

[0021] The second step is to insert the first web 1 from the hole, and insert the upper part of the first web 1 with the inner baffle 6 of the corbel through the upper slot with the opening facing upward;

[0022] The third step, the upper end of the first web 1 is welded to the lower end surface of the upper cover plate 5 of the corbel, the upper slot of the upper part...

Abstract

The invention discloses an installation method for an anti-side-rolling twisted rod seat of a rail car. The method comprises the following steps that a hole allowing a first plate to pass through is arranged in the lower cover plate of a sleeper beam; the first plate is embedded into the hole, and the upper part of the first plate passes through an upper slot with an upward opening to be connected with an inner baffle of the sleeper beam in an insertion manner; the upper end of the first plate is welded with an upper cover plate of the sleeper beam, the upper slot of the first plate is welded with the inner baffle of the sleeper beam, and the middle part of the first plate is welded with a lower cover plate of the sleeper beam; the upper end of a second plate is welded and fastened with the lower cover plate of the sleeper beam; and an anti-side-rolling twisted rod installation block is embedded into lower slots of the first plate and the second plate, and the anti-side-rolling twisted rod installation block is welded and fastened along the slot wall of the lower slot. According to the installation method, the stress situation of an installation structure is improved, and the occurrence of soldering seam fatigue is avoided; and by the adoption of the installation method, the twisted rod installation block falls onto the plates to form a similar shock absorption cushion, and additional force produced by vertical force and bending moment is divided into two parts to bear. According to the installation method, the installation form similar to a toy-block insertion form is adopted, the positioning is more accurate, and the prevention of installation by mistake is realized.

Description

Technical field [0001] The invention relates to a method for installing a rail vehicle anti-side-rolling torsion rod seat, and belongs to the technical field of vehicle interior design. Background technique [0002] Corbel anti-rolling and torsion bars are widely used in subway and high-speed rail vehicles. The structural installation design of this important stressed component requires high structural strength, especially fatigue resistance. The structure of the anti-rolling torsion bar seat is welded The stress on the seam needs to be specially considered for verification, and the fatigue of the weld seam should be avoided in the structural design. Therefore, types such as the use of structural fasteners to connect have also appeared, and the impact characteristics of the fasteners themselves are not very high. In the previous design, the cast seat was mainly assembled and welded to the lower cover of the corbel, and the weld was subjected to the additional load force generate...
