Abstract
The utility model discloses an improved generation passenger train frame belongs to car parts design and processing technical field, and it is unreasonable to have solved traditional back end longeron excurvation structural design, and the atress is big, easily cracks the problem of phenomenon. Main two longerons, interior crossbeam, the outer crossbeam of including, the longeron back end is broken off by the crossbeam, divide into front longitudinal and tail longeron, crossbeam and front longitudinal fixed connection, the tail longeron sinks, adopts connecting plate fixed connection between tail longeron and the crossbeam. The utility model discloses structural design is ingenious, and with longeron excurvation cancellation, the longeron board is thick unchangeable, and with the disconnection of longeron back end before the suspension behind the engine, the tail longeron sinks and opens shelves with the cell type cross -section and subtracted to 180mm by 225mm, is connected longeron and the riveting of tail longeron from the lateral surface with the connecting plate, has so both solved the installation space of engine, and frame weight and cost almost do not have the increase again, the utility model discloses improve with low costs, but wide application in car parts design and processing technical field.
Description
Technical field
The utility model belongs to automobile component design processing technique field, specifically, particularly relates to a kind of improved type bus frame.
Background technology
Tradition bus frame considers the installing space of driving engine, and longeron has been bent outwardly 70mm before back suspension device of engine, and use procedure China and foreign countries bend up place's longeron and occurred cracking.By analysis, former longeron opens a grade 840mm on the one hand, opening shelves after excurvation is 910mm, outer crook moment of flexure will increase suddenly, vehicle frame herein stressed will than other positions increase more because car is engine at extreme rear, rear overhang is longer, vehicle frame back segment is stressed comparatively large, as frame strength surplus is not enough, then can first occur destroying at this; On the other hand, when longeron builds die forming, outer crook is tensile deformation, tensile deformation makes longeron thickness of slab thinning, particularly goes up lower aerofoil edge, through field measurement, the thickness of thinnest part is 5.2mm, and thinning place stressed maximum just, occur that crackle is inexorable trend at this.
For solving the problem, it is consider to change longeron into 7mm by 6mm that tradition solves solution, cracking place intensity is improved, but the strength of material at other position will be made superfluous, longeron weight increases 20kg, and cost increases by 120 yuan/platform, and adds dead weight of vehicle, lose more than gain, improve unsuccessfully.
Summary of the invention
The utility model discloses a kind of improved type bus frame, unreasonable, greatly stressed for solving traditional back segment longeron excurvation structure design, the problem of easy rather.
The utility model is achieved through the following technical solutions:
A kind of improved type bus frame, comprise two longerons, at least one interior crossbeam is provided with between described two longerons, at least one outer crossbeam is provided with outside described longeron, described longeron back segment is disconnected by crossbeam, and be divided into front side member and tail longeron, described crossbeam is fixedly connected with front side member, described tail longeron sinks, and described tail longeron is fixedly connected with adopting connecting panel between crossbeam.
Described tail longeron is grooved steel design, and it is 180mm that the rectangle and trapezium channel section of described tail longeron opens shelves.
Described connecting panel is right-angled trapezium steel plate.
Rivet is adopted to be fixedly connected with between described tail longeron, crossbeam, connecting panel three.
Compared with prior art, the beneficial effects of the utility model are:
The utility model smart structural design, longeron excurvation is cancelled, longeron thickness of slab is constant, disconnected by longeron back segment before back suspension device of engine, tail longeron sinks to rectangle and trapezium channel section is opened shelves being kept to 180mm by 225mm, with connecting panel from lateral surface by longeron and tail longeron riveting, so both solve the installing space of driving engine, vehicle frame weight and cost almost do not increase again, and the utility model improving cost is low, can be widely used in automobile component design processing technique field.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. crossbeam in; 2. outer crossbeam; 3. crossbeam; 4. front side member; 5. tail longeron; 6. connecting panel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of improved type bus frame, comprise two longerons, at least one interior crossbeam 1 is provided with between described two longerons, at least one outer crossbeam 2 is provided with outside described longeron, described longeron back segment is disconnected by crossbeam 3, is divided into front side member 4 and tail longeron 5, and described crossbeam 3 is fixedly connected with front side member 4, described tail longeron 5 sinks, and described tail longeron 5 is fixedly connected with adopting connecting panel 6 between crossbeam 3.
Described tail longeron 5 is grooved steel design, and it is 180mm that the rectangle and trapezium channel section of described tail longeron 5 opens shelves.
Described connecting panel 6 is right-angled trapezium steel plate.
Rivet is adopted to be fixedly connected with between described tail longeron 5, crossbeam 3, connecting panel 6 three.
Crossbeam 3 and front side member 4 adopt the mode of electric welding to be fixedly connected with, and tail longeron 5 sinks, and adopt connecting panel 6 to be fixedly connected with crossbeam 3 rivet.The utility model smart structural design, longeron excurvation is cancelled, longeron thickness of slab is constant, disconnected by longeron back segment before back suspension device of engine, tail longeron 5 sinks and rectangle and trapezium channel section is opened shelves is kept to 180mm by 225mm, with connecting panel 6 from lateral surface by longeron and tail longeron 5 riveting, so both solve the installing space of driving engine, vehicle frame weight and cost almost do not increase again, and the utility model improving cost is low, can be widely used in automobile component design processing technique field.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
