Embodiment 1

[0036] by attaching figure 2 It can be seen that the present invention relates to a rail vehicle anti-rolling torsion bar connecting rod body and connecting rod connection device, including a connecting rod body 1, a connecting rod 2 and a metal joint 3, and the connecting rod body 1 and the connecting rod 2 pass through the metal joint. 3 to form a ball hinge connection, characterized in that the metal joint 3 is an independently detachable metal joint formed by the combination of the metal joint outer cover 4 and the metal joint inner cover 5, and the metal joint 3 and the connecting rod body 1 and the connecting rod 2 The ball hinge connection is a detachable connection.

[0037] The metal joint sleeve 5 is set on the mandrel 6 at the end of the connecting rod 2, and the axial positioning of the metal joint sleeve 5 is carried out through the shaft circlip 7; the metal joint sleeve 4 is embedded in the connecting rod body 1 In the inner hole 8 of the inner hole 8, the axi...

Embodiment 2

[0043] The principle of Embodiment 2 is the same as that of Embodiment 1, but the structure is slightly different. The axial positioning of the metal joint inner sleeve 204 is to make the mandrel at the end of the connecting rod into a stepped shaft, and the lower end of the stepped shaft It is a taper connecting rod shaft 210, an end mandrel 211 whose upper end matches the metal joint inner sleeve 204, and the metal joint inner sleeve 204 transitionally fits on the end mandrel 211; Remove the bolt 201, the detachable bolt 201 fastens the shaft end retaining ring 202, fasten the shaft end retaining ring 202 through the detachable bolt 201 for axial positioning, and only need to remove the detachable bolt 201 from the shaft end retaining ring 202 After unclamping, the metal joint inner cover 204 can be taken out, and the hole of the metal joint cover 205 can be clamped with a circlip 209, so that the metal joint cover 205 can be pulled out from the stepped hole of the connecting...

Abstract

A rail vehicle anti-rolling torsion bar connecting rod body and connecting rod connecting method and device, the connecting rod body and the connecting rod are cooperatively connected by combining detachable metal joints, and the connecting rod body and connecting rod are detachable by combining detachable metal joints The metal joint connection structure, when the connecting rod body and the connecting rod are disassembled, only the detachable metal joint is removed to realize the separation of the connecting rod body and the connecting rod. The invention realizes the detachable structural connection between the connecting rod body and the connecting rod through detachable parts, and when the connecting rod assembly reaches the erection repair period or overhaul period, only the connecting rod end cover needs to be removed and the metal joint can be withdrawn. Maintenance and replacement are carried out, which is convenient for maintenance and replacement, and effectively reduces maintenance costs.

Description

technical field [0001] The invention relates to a connection method and structure of parts of a vehicle anti-roll torsion bar, in particular to a method and device for connecting a connecting rod body and a connecting rod of an anti-roll torsion bar connecting rod. The connection method and device of the connecting rod body and the connecting rod of the torsion bar connecting rod can simplify the connection structure of the connecting rod body and the connecting rod, facilitate maintenance and replacement, and effectively reduce the maintenance cost; it belongs to the technical field of vehicle component connection. Background technique [0002] When a rail vehicle passes through curves and turnouts at high speed or stops on a curve with superelevation, the roll increases significantly, and the load on one side of the wheel is reduced. When encountering strong lateral winds, it may even overturn and become unstable, reducing safety. It is necessary to increase the roll stiff...
