Abstract
A kind of meter-gage motor train unit motor car bogie, comprise framework composition, wheel set axle box device, secondary suspension device, central traction apparatus, foundation brake rigging, actuating device, two crossbeams in framework composition extend to side rail outer and form outer cantilever design, above the crossbeam extended, longitudinal beam is set, longitudinal beam is identical with curb girder height, two is that air bellow is arranged on curb girder and longitudinal beam, makes two to be that the horizontal span of air bellow mount pad strengthens; The end of two curb girders extends sagging, arranges end carriage, as the installation flap seat of brake equipment simultaneously.The utility model widens the horizontal span of secondary suspension, and the crossbeam increasing framework forms outer cantilever design thus makes two to be that the horizontal span of air bellow mount pad strengthens.Curb girder is extended sagging in framework end, end carriage is set simultaneously, as the installation flap seat of brake equipment.Above-mentioned improvement meets dynamic performance, intensity life requirements during vehicle operating, will meet in operational process simultaneously and can not produce interference between each parts.
Description
Technical field
The utility model is applicable to the motor train unit bogie of meter-gage circuit or other narrow gauge.
Background technology
The standard gauge bogie truck (gauge 1435mm) of current application, has passed through long real-world operation, defines ripe structure.Meter-gage motor car bogie is researched and developed based on this structure, but because diminish (the gauge 1000mm) of gauge, corresponding wheelbase also diminishes (becoming 2200mm from 2500mm), cause the transverse distance between framework two curb girder longitudinal centerlines to shorten, cause secondary suspension to adopt traditional design can not meet vehicle driving requirements; Diminishing of wheel-base bogie, Tread brake device is caused to be arranged in the middle part of bogie truck as conventional bogie, can only be arranged in bogie truck end, how at framework end design flap seat, what complete brake equipment is mounted for another problem researched and developed meter-gage motor car bogie and will solve; This two problems can have a strong impact on the safety of vehicle operating.
Utility model content
The purpose of this utility model is to provide the motor car bogie that one is applicable to meter-gage (gauge 1000mm), to meet dynamic performance, intensity life requirements during vehicle operating, will meet in operational process simultaneously and can not produce interference between each parts.
For achieving the above object, the utility model provides a kind of meter-gage motor train unit motor car bogie, comprise framework composition, wheel set axle box device, secondary suspension device, central traction apparatus, foundation brake rigging, actuating device, it is characterized in that: two crossbeams in framework composition extend to side rail outer and form outer cantilever design, above the crossbeam extended, longitudinal beam is set, longitudinal beam is identical with curb girder height, two is that air bellow is arranged on curb girder and longitudinal beam, makes two to be that the horizontal span of air bellow mount pad strengthens; The end of two curb girders extends sagging, arranges end carriage, as the installation flap seat of brake equipment simultaneously.
Foundation brake rigging have employed traditional tread brake structure, and foundation brake unit and band parking brake unit are arranged in the end of framework in skew intersection mode.
The utility model has larger change compared with standard gauge truck frame, widens the horizontal span of secondary suspension, and the crossbeam increasing framework forms outer cantilever design thus makes two to be that the horizontal span of air bellow mount pad strengthens.Be subject to space constraint, foundation brake system cannot be arranged in the middle part of framework, is therefore extended by curb girder sagging in framework end, arranges end carriage simultaneously, as the installation flap seat of brake equipment.Above-mentioned improvement meets dynamic performance, intensity life requirements during vehicle operating, will meet in operational process simultaneously and can not produce interference between each parts.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, the utility model comprises framework composition, wheel set axle box device, secondary suspension device, central traction apparatus, foundation brake rigging, actuating device, two crossbeams 1 in framework composition extend to outside curb girder 2 and form outer cantilever design, above the crossbeam extended, longeron 3 is set, longeron is identical with curb girder height, two is that air bellow 4 is arranged on curb girder and longeron, makes two to be that the horizontal span that air bellow is installed strengthens; The end of two curb girders extends sagging, arranges end carriage 5, as the installation flap seat 6 of brake equipment simultaneously.
Wheel set axle box device have employed the structural shape of ripe application at present, and axle box 7 is inblock cast, primary spring 8 is conical rubber spring.
In order to improve the safety of vehicle operating, adopting traditional air bellow to arrange and can not meet demanding kinetics, therefore adopt the horizontal span Widening Design of secondary suspension.In order to make to ensure in vehicle operating that vehicle floor face height is constant, be provided with height adjuster 9, this meter-gage motor car bogie requires running velocity 120km/h, therefore sets up anti-snakelike shock absorber 10, increases the stability of vehicle operating.
Central traction apparatus is consistent with current standard gauge structure that bogie truck uses.
Foundation brake rigging have employed traditional tread brake structure, but arrangement has carried out new design, and foundation brake unit 11 and band parking brake unit 12 have been arranged in the end of framework in skew intersection mode.
Actuating device forms primarily of traction electric machine 13 and gear case 14, and in order to be applicable to meter gauge bogie, joint supply business has all carried out miniaturized design to traction electric machine and gear case, and after its more compact structure, installation, requisite space is less compared with existing structure.
Claims (2)
