Abstract
The cross beam for the urban public transport passenger car frame is longitudinally Z-shaped and is of an integral structure, and is characterized in that the cross section of the cross beam is of a closed annular structure. Longeron about the frame is connected to the main effect of crossbeam, guarantees frame torsional rigidity. The steel pipe for the cross beam is formed by bending. Compared with the prior art, the beneficial effects of the utility model are that: the beam body is formed by bending a steel pipe, so that the beam is light in weight, the preparation quality of the whole vehicle is reduced, the beam is convenient to manufacture and form, and the performance of the whole vehicle is improved.
Description
Technical field
The utility model relates to automobile vehicle carriage crossbeam, relates in particular to the low inlet in a kind of Qianmen, passenger zone low floor, the urban transit bus vehicle frame crossbeam of the different longerons of height about employing.
Background technology
Along with the epoch are progressive, urban transit bus is more and more higher to the requirement of low inlet low floor.Make things convenient for passenger getting on/off, reduce passenger getting on/off time and difficulty and become modern bus design-calculated theme.Consider that driver zone driver sight line can not be too low, and the manufacturing cost problem, the design vehicle frame adopts the high right low left and right sides asymmetric girder work in a left side at front axle with the relative vehicle forward direction of leading portion often, and general left longeron is than the high 150-300mm of right vertical beam.For guaranteeing the torsional stiffness of vehicle frame, need crossbeam to connect between left-right longeron.
The crossbeam that adopts mainly contains now: punch forming Z font grooved crossbeam and welding moulding Z font grooved crossbeam.Z font grooved crossbeam is made in punch forming needs large mold, makes difficult forming; Welding moulding Z font grooved crossbeam, material can change through the performance of each side behind the high temperature in welding process, the bad problem of stress concentration that also exists of weld seam post-processing, thereby make the overall beam main quality can not get guaranteeing, and part is heavier, influence complete vehicle curb weight, and then influence vehicle performance.
The utility model content
The purpose of this utility model is to need large mold in order to solve the punch forming Z font grooved crossbeam that exists in the above-mentioned background technology, make difficult forming and weld moulding Z font grooved crossbeam quality and can not get guaranteeing, and the heavier problem of part, provide a kind of have in light weight, make and be shaped conveniently the urban transit bus vehicle frame crossbeam that quality can guarantee.
The utility model adopts following technical scheme for achieving the above object: a kind of urban transit bus vehicle frame crossbeam, and it is Z-shaped that this crossbeam vertically is, and is integral structure, and the cross-sectional plane that it is characterized in that described crossbeam is the closed circular structure.
Above-mentioned crossbeam two ends can be welded with can with chassis side rail bonded assembly connecting panel 2.
Above-mentioned crossbeam two ends can also be welded with the brace panel 3 that links to each other with connecting panel.
In such scheme, described crossbeam is a round steel pipe.
The main effect of crossbeam described in the utility model is to connect the vehicle frame left-right longeron, guarantees chassis torsion rigidity.This crossbeam passes through bending and molding with steel pipe.Connecting panel 2 and brace panel 3 constitute the bindiny mechanism of crossbeams and chassis side rail, are welded on the two ends of main body of cross-beam.
Compared with prior art, the beneficial effects of the utility model are: main body of cross-beam steel pipe bending and molding, and in light weight, alleviated the curb mass of car load, make and be shaped conveniently, improve vehicle performance.
Description of drawings:
Fig. 1 is the utility model structural representation;
Wherein, 1-crossbeam, 2-connecting panel, 3-brace panel, 4-left side longeron, 5 right vertical beams.
The specific embodiment
Referring to Fig. 1, the utility model mainly is made up of crossbeam 1, connecting panel 2 and brace panel 3, and wherein, crossbeam 1 is the zigzag of bending, and by bending and molding, drop is 200mm with steel pipe.Steel pipe can be preferably round steel pipe for rectangular tube, special pipe, and its two ends respectively are welded to connect plate 2 and brace panel 3, and connecting panel 2 passes through bolted connection with chassis side rail, also can connect with welding.
Claims (4)
1. urban transit bus vehicle frame crossbeam, it is Z-shaped that this crossbeam vertically is, and is integral structure, and the cross-sectional plane that it is characterized in that described crossbeam is the closed circular structure.
2. a kind of urban transit bus vehicle frame crossbeam according to claim 1, it is characterized in that described crossbeam two ends be welded with can with chassis side rail bonded assembly connecting panel (2).
3. a kind of urban transit bus vehicle frame crossbeam according to claim 2 is characterized in that described crossbeam two ends are welded with the brace panel (3) that links to each other with connecting panel.
4. according to the described a kind of urban transit bus vehicle frame crossbeam of arbitrary claim in the claim 1 to 3, it is characterized in that described crossbeam is a round steel pipe.
