Abstract

The utility model discloses a frame for a rail commuter car bogie. In order to meet the increasingly tense requirements of urban rail transit vehicle bogies for fast speed, good curve passing performance, good vehicle running stability, and light weight, the frame for rail commuter vehicles includes a left side beam and a right side beam. It forms an H-shaped frame structure with the middle beam; the left beam and the right beam are equipped with a secondary vertical shock absorber seat, a secondary air spring seat, an anti-snaking shock absorber seat, a rotating arm positioning seat and an anti-rolling Mounting seat; the middle beam is arranged with a brake hanging seat, a gear box hanging seat, a motor hanging seat and a traction seat. The utility model can be widely applied to the bogies of rail commuter cars, subways and EMUs, and provides a good, comfortable and convenient transportation tool for alleviating the increasingly tense urban rail traffic.

Description

A kind of track scheduled bus bogie truck framework

Technical field

The utility model relates to city rail scheduled bus Automobile structure design field, relates in particular to a kind of framework that is applied on the city rail scheduled bus bogie truck.

Background technology

At present, domestic city track light rail, subway and motor train unit bogie all adopt diaxon Bo formula bogie truck, bogie truck also generally adopts " day " font or " H " type framework with framework, framework integral body generally adopts welded structure, " day " font framework is in the majority with body beam version, " H " type truck side sill adopts body beam, intermediate transverse girder has the body beam of employing structure, the crossbeam of employing steel-tube construction is also arranged, but, each framework is owing to satisfy the difference of bogie truck functional requirement, each framework structure form is totally different, especially each mount pad version, the layout feature difference is very large; The speed of track scheduled bus is fast, curving performance good, vehicle smoothness good, the weight-saving requirement but these bogie trucks all are difficult to adapt to.

The utility model content

Fast for speed for the urban rail transit vehicles bogie truck that satisfies present growing tension, curving performance good, vehicle smoothness good, the weight-saving requirement, the utility model aims to provide a kind of track scheduled bus bogie truck framework, this framework can extensively be suitable on track scheduled bus, subway and the motor train unit bogie, for the urban track traffic of alleviating growing tension provides good, comfortable, the vehicle easily.

To achieve these goals, the technical scheme that adopts of the utility model is:

A kind of track scheduled bus bogie truck framework comprises by left side beam, right side beam and intermediate transverse girder forming H type framework structure; Its constructional feature is that being equipped with two on described left side beam and the right side beam is that vertical damper holder, two is air bellow seat, anti-hunting Damper seat, pivoted arm positioning seat and the anti-mount pad that sidewinders; Be furnished with drg Holder for hanging household utensiles, gear case Holder for hanging household utensiles, motor hanging seat and traction seat on the described intermediate transverse girder.

Below be the technical scheme of further improvement of the utility model:

As a kind of concrete version, described left side beam and right side beam are the body beam structure, and described intermediate transverse girder is steel-tube construction.

In order to guarantee reliable welding quality, described left side beam, right side beam and intermediate transverse girder all adopt low-temperature (low temperature) vessel plate 16MnDR material to make.

By said structure, the urban rail transit vehicles bogie truck that the utility model is mainly present growing tension provides that a kind of safety performance is high, reliable and stable, multiple functional, the weight-saving framework, to satisfy the requirement that bogie truck speed is fast, curving performance good, vehicle smoothness is good.The utility model not only can be suitable for city rail scheduled bus bogie truck, and can be applied to city rail subway and the motor train unit bogie of car.In addition, the utility model can be applicable to track scheduled bus power and non-power truck, can realize that power truck and non-power truck exchange fully.

Compared with prior art, the beneficial effects of the utility model are:

1) the whole H type welded structure that adopts of framework, material mainly adopts low-temperature (low temperature) vessel plate 16MnDR to form, and overall construction intensity is high;

2) left and right sides curb girder adopts body beam, and intermediate transverse girder adopts steel-tube construction, and the framework integral structure adopts light-weight design;

3) framework left and right sides curb girder and intermediate transverse girder are to satisfy bogie truck good operation stability, requirement that safety performance is high, have arranged various mount pads, and be simple in structure, multiple functional;

4) framework satisfies the requirement that power and non-power truck exchange fully, and commonality is good;

5) simple in structure, easy to maintenance.

Below in conjunction with drawings and Examples the utility model is further elaborated.
