Abstract
The utility model relates to a vehicle longeron and have frame of this longeron. Longeron part is divided into the anterior segment in proper order, is out of shape section and back end including longeron body, this longeron body from one end to the other end, the anterior segment, be out of shape section and back end and be integrated into one piece, the anterior segment, be out of shape section and back end have respectively last airfoil reach under the airfoil, wherein, the cross -section of longeron body is the C type. Compare many straight structures that C type web is connected for the longeron on the prior art frame, the longeron that this scheme provided uses steel less, thus it is with low costs, also be favorable to the vehicle lightweight.
Description
Technical field
The utility model relates to vehicular field, specifically, relates to a kind of vehicle rail and has the vehicle frame of this longeron.
Background technology
In the middle of the common city bus of current producer and private bus chassis, for making the step height of car load be up to state standards requirement, in space, cloth is set up, and the requirement for height on the upper plan range ground of its vehicle frame is higher, for reaching this layout effect, the mode of the straight longeron overlap joint of frequent employing many is arranged, and many straight longeron place C type webs connect, and the shortcoming of this arrangement is, the material usage of steel plate is large, cost is high, and can increase complete vehicle quality, is unfavorable for vehicle lightweight.
Therefore, how to innovate existing car beam, be the problem that those skilled in the art need solution badly.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of vehicle rail and has the vehicle frame of this longeron.The vehicle rail that this programme provides, can reduce the weight of whole chassis frame, be conducive to the lightweight of vehicle, and can reduce manufacturing cost.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of vehicle rail, comprise longeron body, this longeron body passes through and is divided into leading portion, deformation section and back segment successively, and leading portion, deformation section and back segment are all formed in one, and described leading portion, deformation section and back segment have top airfoil and lower aerofoil respectively;
Wherein, the cross section of described longeron body is C type.
Preferably, the length of described deformation section is 255mm.
Preferably, the junction of described deformation section and leading portion is fillet.
Preferably, the junction of described deformation section and back segment is fillet.
Preferably, the thickness of described top airfoil and lower aerofoil is 5-15mm.
Preferably, the top airfoil of described leading portion and the top airfoil drop of back segment are 180mm.
Preferably, in described leading portion, deformation section and back segment arbitrary section, the distance of upper and lower aerofoil is 200-250mm.
This programme additionally provides a kind of vehicle frame, and this vehicle frame has above-mentioned vehicle rail.
The beneficial effects of the utility model are: be the structure that many straight longeron places connect with C type web compared to vehicle frame in the middle of prior art, the longeron that the basic scheme of one-sided use one provides can complete the assembling of vehicle frame, be conducive to vehicle lightweight, while minimizing car beam quality, also reduce rolled steel dosage.

Detailed description of the invention
Below in conjunction with accompanying drawing, this programme is described in detail.
Embodiment 1: a kind of vehicle rail, its structure as shown in Figure 1-2, comprise longeron body 1, this longeron body 1 passes through and is divided into leading portion 2, deformation section 3 and back segment 4 successively, leading portion 2, deformation section 3 and back segment 4 are all formed in one, and leading portion 2, deformation section 3 and latter 4 sections have top airfoil 5 and lower aerofoil 6 respectively;
Wherein, the vertical cross-section of described longeron body 1 is identical with C-type steel.
The starting point of described deformation section 3 is A point, and end point is B point, and A point is 255mm to the length E of B point.
Described deformation section 3 is fillet with the junction of leading portion 2.
Described deformation section 3 is fillet with the junction of back segment 4.
The thickness of described top airfoil 5 and lower aerofoil 6 is respectively 5-15mm.
Described top airfoil 5 and lower aerofoil 6 width C are 40-100mm.
The top airfoil of described leading portion 2 and the top airfoil drop D of back segment 4 are 180mm.
In described leading portion 2, deformation section 3 and back segment 4 arbitrary section, the distance H of upper and lower aerofoil is 200-250mm.
As shown in Figure 3, this programme additionally provides a kind of vehicle frame 7, this vehicle frame 7 is provided with the longeron body 1 of the present embodiment, and longeron body 1 is connected with other parts of vehicle frame 7 by C type web 8.
The benefit of said structure is, the longeron that this programme provides uses steel less, so cost is low, is also conducive to vehicle lightweight.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
