Abstract
The utility model provides a connecting structure of a segmented vehicle crossbeam, which comprises a front crossbeam, a rear crossbeam, a front connecting plate and a rear connecting plate, wherein the front connecting plate is fixed at the rear end of the front crossbeam, the rear connecting plate is fixed at the front end of the rear crossbeam, the front connecting plate and the rear connecting plate are detachably connected together through a plurality of connecting bolts, and the contact surfaces of the front connecting plate and the rear connecting plate are mutually matched cascaded surfaces. Because the connecting bolts are adopted for detachable connection, the length of a frame can be effectively shortened when in transportation; meanwhile, because a connecting surface for connecting the front connecting plate and the rear connecting plate of the front crossbeam and the rear crossbeam adopts a structural form of step matching, the connecting bolts basically bear no shearing force, thereby greatly improving the connecting strength of the front crossbeam and the rear crossbeam, and effectively improving the safe reliability of the segmented connection of the front crossbeam and the rear crossbeam.
Description
Technical field
The utility model relates to a kind of connection structure of sectional type vehicle crossbeam.
Background technology
For some special vehicle, in order to save traffic cost, transportation often need pack into the container vehicle frame.Because the length of freight container will meet international standard, can not extend arbitrarily, therefore when the vehicle frame length of as ready vehicle surpassed internal container length, normally the crossbeam with this as ready vehicle was designed to two sections types of attachment of detouchable.In order after transportation, two sections crossbeams of detouchable to be connected, common preceding connecting panel of rearward end captive joint at preceding crossbeam, connecting panel behind one of the leading section captive joint of back crossbeam, forward and backward connecting panel is connected together with knockdown pieces such as some tie bolts, thereby forward and backward crossbeam is connected together.Because crossbeam is the most important parts of vehicle frame, so the Joint strenght between the segmentation crossbeam will be directly connected to the bulk strength of vehicle frame.Connection between traditional segmentation crossbeam is the plane docking mode, in vehicle long-term use process, is easy to generate thread looseness, and then makes tie bolt be subjected to shear action and deform easily even phenomenon such as fracture, brings great potential safety hazard.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of connection structure of attachment security failure-free sectional type vehicle crossbeam is provided.
For achieving the above object, the utility model adopts following technical scheme:
The connection structure of sectional type vehicle crossbeam of the present utility model comprises preceding crossbeam, back crossbeam, is fixed on the preceding connecting panel of described preceding crossbeam rearward end and is fixed on the described back connecting panel of crossbeam leading section afterwards.Connecting panel, back connecting panel are detachably connected by several tie bolts before wherein said, and the contact surface of described preceding connecting panel, back connecting panel is the cascaded surface of mutual coupling.
The shoulder height of cascaded surface is half of preceding connecting panel or back connecting panel thickness on the described forward and backward connecting panel.
Wherein also comprise and be separately fixed between described preceding connecting panel and the preceding crossbeam and back connecting panel and the gussets of the reinforcement of some between the crossbeam afterwards.
The advantage and the good effect of the connection structure of sectional type vehicle crossbeam described in the utility model are: because the new middle tie bolt that adopts of this practicality is detachably connected forward and backward crossbeam, disassembled for transport can effectively reduce the length of vehicle frame; Simultaneously because the version that the joint face of forward and backward connecting panel adopts step to cooperate, tie bolt only plays the effect that connects fastening forward and backward connecting panel, substantially do not bear shearing force, thereby make the Joint strenght of forward and backward crossbeam increase substantially, improved bonded assembly safe reliability between the forward and backward crossbeam of segmentation bonded assembly effectively.
With reference to the accompanying drawing description of a preferred embodiment, above-mentioned and other purpose of the present utility model, feature and advantage will be more obvious by following.
Description of drawings
Fig. 1 is the structural representation of the connection structure of sectional type vehicle crossbeam of the present utility model;
Fig. 2 is that A among Fig. 1 is to view;
Fig. 3 is that B among Fig. 1 is to view.
Wherein, 1. preceding crossbeam; 2. preceding connecting panel; 3. connecting panel after; 4. crossbeam after; 5. reinforcement gusset; 6. tie bolt.
The specific embodiment
To describe specific embodiment of the utility model in detail below.Should be noted that the embodiments described herein only is used for casehistory, is not limited to the utility model.
As Fig. 1, Fig. 2 and shown in Figure 3, the connection structure of sectional type vehicle crossbeam of the present utility model comprises the preceding crossbeam 1 and the back crossbeam 4 that are welded on the vehicle frame.Connecting panel 2 before preceding crossbeam 1 rearward end is fixed with, back crossbeam 4 leading sections are fixed with back connecting panel 3.Preceding connecting panel 2, back connecting panel 3 are detachably connected by several tie bolts 6.The contact surface of preceding connecting panel 2, back connecting panel 3 is the cascaded surface 7 that mates mutually, the shoulder height of cascaded surface 7 is half of preceding connecting panel 2, back connecting panel 3 thickness, and step is positioned at the midway location of connecting panel, certainly be not limited to this midway location, connecting panel lean on or by upper/lower positions also be feasible.The contact surface of the forward and backward connecting panel in the present embodiment has only a step, and under the situation that guarantees each connecting panel intensity, connecting panel also can be provided with a plurality of steps, and this is specially adapted to the thicker situation of connecting panel thickness.For the Joint strenght between the Joint strenght between connecting panel 2 before strengthening and the preceding crossbeam 1 and back connecting panel 3 and the back crossbeam 4, be welded with the some reinforcement gussets 5 that are arranged in parallel respectively between preceding connecting panel 2 and the preceding crossbeam 1 and between back connecting panel 3 and the back crossbeam 4.
In the utility model, preceding connecting panel 2 closely cooperates with back connecting panel 3, when frame beam carries, because preceding connecting panel 2 is the cascaded surface 7 that mates mutually with the contact surface of back connecting panel 3, the suffered bearing capacity transmission of vehicle frame is the interaction force between preceding connecting panel 2 and the back connecting panel 3,6 of tie bolts play the fastening effect of connection, and do not bear shearing force substantially.So the connection reliability height of forward and backward connecting panel, so in the utility model, the attachment security between the preceding crossbeam of segmentation and the back crossbeam, reliable.
Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.The spirit or the essence that do not break away from utility model because the utility model can specifically be implemented in a variety of forms, so be to be understood that, the foregoing description is not limited to any aforesaid details, and should be in the spirit and scope that claim limited of enclosing explain widely, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
