Abstract
A B-type metro bogie framework comprises cross beams, side beams, longitudinal beams, a motor hanging base and a gearbox hanging base, and is characterized in that the longitudinal beams are box-type structures. As the longitudinal beams are the box-type structure, the B-type metro bogie framework is reasonable in strength design, low in local position stress, reasonable in structure design and fine in welding process, is not easy to cause fatigue cracks during actual application, and can meet requirements of normal service life.
Description
Technical field
The utility model relates to a kind of framework that is applied to Type B subway car bogie truck, especially relates to a kind of framework that is applied to adopt the motor car bogie of tread brake technology.
Background technology
Have a lot of cities all to build subway now in the world, wherein using many is Type B subway car.The truck frame that is used for Type B subway car is made up of crossbeam and curb girder mostly, and crossbeam couples together two curb girders, forms " H " type framework.Framework need couple together the various piece of bogie truck as the skeleton of bogie truck, bears the effect of dead weight of vehicle and year member's load, and stands circuit and impact the severe jolt that causes.
At present, the truck frame of Type B subway, the truck frame of particularly homemade Type B subway car, be improved on the early stage abroad truck frame basis mostly, pass through welding by longitudinal beam mutually with crossbeam, so the framed intensity design is unreasonable, causes local location stress higher; Structure design is unreasonable, and welding process is bad; In practice,, be difficult to satisfy the requirement in normal service life because these shortcomings cause early endurance crack occurring.
The utility model content
Technical problem to be solved in the utility model provides a kind of framework of new construction, not only can satisfy " various piece of bogie truck is coupled together; bear dead weight of vehicle and carry the effect of member's load; and stand circuit and impact the severe jolt that causes " basic demand, also to overcome the defective that existing framework exists.
For solving the problems of the technologies described above, the utility model provides a kind of Type B subway bogie frame, comprises crossbeam, curb girder, longitudinal beam, motor hanger and gear box bracket, and it is characterized in that: longitudinal beam is designed to box-structure.
The utility model longitudinal beam is designed to box-structure, so framed intensity is reasonable in design, and local location stress is low; Reasonable in design, welding process is good, is not prone to endurance crack in practice, can satisfy the requirement in normal service life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, 1 is curb girder, 2 is crossbeam, and 3 is longitudinal beam, and 4 is gear box bracket, 5 is motor hanger, crossbeam and curb girder are formed " H " type framework, and crossbeam is the solid drawn pipe structure, by two longitudinal beams two solid drawn pipes is coupled together, form s crossbeam frame, welding motor hanger and gear box bracket above the s crossbeam frame; Curb girder is the die mould welded structure, becomes box-structure by the die mould bending part with the base plate assembly welding, and two curb girders are connected by s crossbeam frame, and longitudinal beam is designed to box-structure.
During use, the truck side sill bottom can be connected with single stage suspension, is connected with secondary suspension in the middle of the curb girder top, and gear box bracket is hung oneself and mentioned the roller box suspension rod, and motor is installed on the motor hanger.
Claims (1)
1. a Type B subway bogie frame comprises crossbeam, curb girder, longitudinal beam, motor hanger and gear box bracket, and it is characterized in that: longitudinal beam is designed to box-structure.
