Abstract
The utility model relates to a new automobile frame, in particular to an improvement to the heavy automobile frame, and the automobile frame belongs to the designing and manufacturing technical field of the parts of the automobile. The automobile frame is riveted or bolted by a left longitudinal beam, a right longitudinal beam and a cross beam, and the right longitudinal beam and the left longitudinal beam in the front section of the frame are symmetrically folded into a structure of wide in front while narrow in the rear end with the center line of the frame as a symmetry axis outward. The automobile frame can avoid and overcome the disadvantages of the prior art, and the automobile frame can be provided with an engine with a large power and a large size. The automobile frame can be provided with a large format tyre when meeting the width requirement of the whole automobile of the actual legislation. The automobile frame can raise the performance of the whole automobile, save the cost and create conditions for raising the efficiency and benefit, so the automobile frame can make a base for the chassis of the whole automobile.
Description
Technical field
The utility model relates to a kind of new automobile vehicle frame, particularly to the improvement of heavy automobile chassis frame, belongs to the design processing technique field of automobile component.
Background technology
Automobile chassis frame is the basic component of car chassis, and traditional automobile chassis frame is to be made of riveted joint of left and right longeron and some crossbeams or bolt, and left and right longeron is two straight beams, and left and right longeron is equidistant arrangement in parallel.Raising along with operating needs, traditional vehicle frame has shown some shortcoming and defect, such as needing wide type vehicle frame when dress during with high-power large scale driving engine, and need narrow type vehicle frame to adorning under the condition of car load width requirement with oversize tyre according to current law, the two can not be taken into account.The structural limitations of orthodox car vehicle frame the raising and the development of vehicle performance.
Contriver of the present utility model is through studying repeatedly and putting into practice, and having found finally has a kind of technical scheme that addresses the above problem better.
Summary of the invention
The purpose of this utility model is exactly for fear of with the deficiency that overcomes prior art and shortcoming and a kind of later-model automobile chassis frame is provided, the utility model improves the vehicle frame of heavy motor vehicle, satisfying under the condition of current law to the car load width requirement, making it can satisfy the technical requirements of dress with high-power large scale driving engine and oversize tyre.This vehicle frame is saved cost for improving vehicle performance, raises the efficiency with benefit and has created condition, thereby lay the first stone for the foundation of integer chassis.
The utility model relates to a kind of new automobile vehicle frame, and it is to be made of left and right longitudinal and cross beam riveted joint or bolt, and the left and right longeron of vehicle frame leading portion is that axis of symmetry is bent to form front wide and rear narrow body frame structure for automotive to external symmetry with the vehicle frame line of centers.The width of the wide shape structure of vehicle frame leading portion is 860mm-940mm, and the length of wide shape structure is 2400mm-2700mm; The width of the narrow shape structure of vehicle frame back segment is 780mm-820mm.The width of the wide shape structure of vehicle frame leading portion is preferably 865mm-940mm in addition, and the length of wide shape structure is preferably 2500mm-2600mm; The width of the narrow shape structure of vehicle frame back segment is preferably 780mm-800mm.The length of the wide shape structure of vehicle frame and the transition phase of narrow shape structure is 300mm-600mm, and the length of the wide shape structure of vehicle frame and the transition phase of narrow shape structure is preferably 400mm-500mm.The total length of vehicle frame is 5500mm-11900mm.
Description of drawings
Fig. 1 is a structure front elevation of the present utility model;
Fig. 2 is a structure birds-eye view of the present utility model.
As shown in the figure, the new automobile vehicle frame is to be made of left longeron 1, right vertical beam 2 and crossbeam 3 riveted joints or bolt, the left longeron 1 of vehicle frame leading portion, right vertical beam 2 are that axis of symmetry is bent to form front wide and rear narrow body frame structure for automotive to external symmetry with the vehicle frame line of centers, i.e. the transition phase 6. of 5 on the wide shape structure 4 of the narrow shape structure 4 of the wide shape structure 5 of vehicle frame leading portion, vehicle frame back segment and vehicle frame and narrow shape structure
The specific embodiment
Further set forth content of the present utility model below by drawings and Examples:
The embodiment that accompanying drawing showed is a kind of later-model heavy motor vehicle vehicle frame, and it is to be made of left longeron 1, right vertical beam 2 and crossbeam 3 riveted joints, and the connection between frame member can also be taked the form of bolt certainly.The length of crossbeam 3 and radical should be looked the specific requirement of vehicle vehicle frame and determine.The left longeron 1 of vehicle frame leading portion, right vertical beam 2 are that axis of symmetry forms front wide and rear narrow body frame structure for automotive to the external symmetry bending with the vehicle frame line of centers.The width b of the wide shape structure 5 of vehicle frame leading portion is 860mm one 940mm, and the length d of wide shape structure 5 is 2400mm-2700mm; The width b ' of the narrow shape structure 4 of vehicle frame back segment is 780mm-820mm.The width b of the wide shape structure 5 of the selected vehicle frame leading portion of present embodiment is 900mm, and the length d of wide shape structure 5 is chosen to be 2600mm, and the width b ' of the narrow shape structure 4 of vehicle frame back segment is chosen to be 800mm.The wide shape structure 4 of vehicle frame is chosen to be 450mm with the length e of the transition phase of narrow shape structure 5.The total length of vehicle frame is 10000mm.
This chassis side rail is a channel-section rail, and its opening laterally bends towards the vehicle frame inboard, and the web of front and back section channel-section rail is parallel to each other.Press the longeron section height and divide, longeron has equal altitudes and front end to diminish two kinds; Press the longeron section width and divide, longeron such as has to diminish two kinds at width and front end; Whether strengthen dividing by longeron, longeron has the veneer longeron and adds two kinds of inner panel longerons.Present embodiment be a kind of equal altitudes, etc. the girder work of width.Various component forms can be looked the vehicle difference and carry out multiple combination.
The deficiency and the shortcoming of prior art avoided and overcome to the utility model, and it improves the vehicle frame of heavy motor vehicle, because this vehicle frame leading portion width dimensions is bigger, it can install high-power large scale driving engine; Because vehicle frame back segment width dimensions is narrower, so satisfying under the condition of current law to the car load width requirement, it can make the back axle of assembling leaf spring type suspension adorn with oversize tyres such as 12.00-200.This vehicle frame is saved cost for improving vehicle performance, raises the efficiency with benefit and has created condition, thereby lay the first stone for the foundation of integer chassis.
