Small-space large-load coupler seat for broad track metro vehicle

Abstract

The invention discloses a small-space large-load coupler seat for a broad track metro vehicle, and belongs to the field of metro vehicle coupler seat structures. The small-space large-load coupler seat is of a bilateral symmetry structure which is integrally cast, wherein the upper end of the coupler seat is a mounting end, the left side and the right side of the upper end are respectively provided with four coupler seat mounting holes, and the coupler seat mounting holes are provided with internal threads; two buffer fixing base mounting holes are formed in a bilateral symmetry mode in the middle position of the front end of the upper end, two buffer fixing base mounting holes are also formed in a bilateral symmetry mode in the middle position of the front end of the lower end, and the buffer fixing base mounting holes are also provided with internal threads; a half cylindrical surface is arranged between the two buffer fixing base mounting holes in the upper end, and another half cylindrical surface is arranged between the two buffer fixing base mounting holes in the lower end; the middle position of the left end and the middle position of the right end are respectively provided with a lightening hole. According to the small-space large-load coupler seat for the broad track metro vehicle, the upper end face of the coupler seat is a mounting surface so that sufficient operation space can be reserved for the operation that a torque spanner is used for applying large-load tightening torque on an erection bolt, and the design requirements of broad track vehicle coupler seats are met.

Description

technical field [0001] The invention belongs to the field of coupler seat structures for urban railway vehicles, in particular to a coupler seat with small space and large load for wide-gauge subway vehicles. Background technique [0002] Most of the existing urban railway vehicles are standard-gauge vehicles, which meet the vehicle requirements of wide-gauge vehicles, that is, meet the interface requirements of coupler, electrical and braking systems, and meet the requirements of high-load working conditions. [0003] Compared with the existing regular-gauge subway vehicles, the wide-gauge subway vehicles adopt a new design of the traction beam structure, which uses a closer beam and reduces the space of the original subway coupler seat and bogie , At the same time, the installation location and structure of the electrical system and braking system have also been changed. [0004] At the same time, since the original coupler seat adopts a side-wall installation structure, ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that the existing side wall-mounted coupler seat cannot apply sufficient tightening torque in a narrow space, and thus cannot meet the design requirements of the coupler seat of a wide-gauge subway vehicle, the present invention provides a wide-gauge subway vehicle with a small space and a large load Coupler seat
