Embodiment 1

[0043] Embodiment 1: as Figure 7 and Figure 8 As shown, an anti-rolling torsion bar end structure to prevent galvanic corrosion, which includes a coating 6 sprayed on the outer peripheral surface of the torsion bar end 312, the coating 6 is located at the end of the torsion bar after assembly 312 and the position between the torsion bar bearing 2, use the coating 6 to prevent direct contact of different materials and prevent the formation of a current loop and the main sealing ring 7 arranged between the torsion bar end face 311 of the torsion bar and the torsion bar bearing end face 211, use The torsion bar bearing end surface 211 presses the main sealing ring 7 onto the torsion bar end surface 311 of the torsion bar, so that a sealed fitting surface is formed on the torsion bar bearing end surface 211, preventing external electrolyte from entering the torsion bar bearing, Thereby preventing the occurrence of galvanic corrosion. In this embodiment, the coating is applied ...

Embodiment 2

[0057] Embodiment 2: The applicant conducted further research on the possibility of failure of the sealing performance of the spline joint between the torsion bar and the torsion arm through various tests and spline sealing performance analysis.

Abstract

The invention discloses an end part structure of an antiroll torsion bar capable of preventing galvanic corrosion. The structure comprises a coating sprayed on the outer peripheral surface of a torsion bar end part; after assembly, the coating is located between the torsion bar end part and a torsion bar bearing; a main sealing ring is arranged between a torsion bar end surface of a torsion bar and the end surface of the torsion bar bearing; the end surface of the torsion rod bearing is utilized so that the main sealing ring is tightly attached to the torsion bar end surface of the torsion rod; and therefore, a sealed attachment surface is formed on the end surface of the torsion rod bearing in order to prevent galvanic corrosion. During an application process, rusting corrosion at the torsion rod end part is avoided. The rejection rate of an antiroll torsion bar device is reduced. The cost of overhaul is lowered. Additionally, limits of foreign technology are removed. The maintenancemarket is automatically mastered.

Description

technical field [0001] The invention relates to an end structure of an anti-rolling torsion bar, in particular to an end structure of an anti-rolling torsion bar for preventing galvanic corrosion. 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 stiffness of the vehicle to limit its roll angle, but it cannot affect the vibration characteristics of the vehicle such as ups and downs, yaw, shake head, telescopic and nod. [0003] The anti-roll torsion bar component device is installed on the rail transit vehicle. When the rail vehicle is rolling, the torsion bar shaft is twisted and deformed, and together with other components, it provides the roll stiffness required for t...
