Description
Technical field
The utility model relates to the anterior guard technology of commercial vehicle/comm..vehicle, is specifically related to truck front lower portion fail-safe structure.
Background technology
Commercial vehicle/comm..vehicle front lower portion is protected, and requirement can meet front lower portion protection requirements, and size, intensity and moulding will meet design requirement.At present, the front lower protection of domestic automobile producer mostly is and the one-piece construction of vehicle frame one, or to mark time the structure of synthesis type with one-level; Front lower protection is non-dismountable, complex structure, and profile unsightly; During maintenance chassis member, dismounting side protection parts are inconvenient.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides structure simple, good looking appearance, for convenience detach and truck front lower portion fail-safe structure installed.
To achieve these goals, the technical solution adopted in the utility model is:
Truck front lower portion fail-safe structure, comprises crossbeam, and described cross rail inner is provided with the connection bracket be connected with truck frame lower aerofoil; Described connection bracket and truck frame lower aerofoil are bolted.
Described crossbeam is rectangular square tube, and the bending to the inside of end, described cross rail outer two ends forms bending part.
Described connection bracket is a pair, and a pair connection bracket symmetry is located on crossbeam.
Described bending part symmetry is located on described crossbeam.
Described connection bracket and described beam welding.
Described connection bracket comprises the contiguous block be connected with described crossbeam, and described contiguous block top is provided with the mounting hole installing described bolt, and described contiguous block top exceeds described crossbeam, and described contiguous block is provided with the through hole communicated with described mounting hole.
Described bolt is connected with the project-welding nut that truck frame lower aerofoil welds.
The utility model has the advantage of: truck front lower portion fail-safe structure, not only structure is simple, good looking appearance, and connection bracket is connected with vehicle frame lower aerofoil by bolt, while can meeting requirement of shelter, easy for installation, is convenient to dismounting; Can effectively enhance productivity, cost-saving.
Accompanying drawing explanation
Mark in the content expressed each width accompanying drawing of the utility model specification sheets below and figure is briefly described:
Fig. 1 is the utility model truck front lower portion fail-safe structure schematic diagram.
Fig. 2 is the utility model truck front lower portion fail-safe structure and truck frame assembling schematic diagram.
Mark in above-mentioned figure is:
1, crossbeam; 2, connection bracket; 3, bolt; 4, vehicle frame, 5, contiguous block, 6, through hole, 7, bending part.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 and 2, truck front lower portion fail-safe structure, comprises crossbeam 1, is provided with the connection bracket 2 be connected with truck frame 4 lower aerofoil inside crossbeam 1, is protection face outside crossbeam 1; Connection bracket 2 is connected by bolt 3 with truck frame 4 lower aerofoil.Truck front lower portion fail-safe structure not only structure is simple, good looking appearance, and connection bracket 2 is connected with vehicle frame lower aerofoil by bolt 3, while can meeting requirement of shelter, easy for installation, is convenient to dismounting; When keeping in repair chassis member, side can be facilitated to protect the dismounting of parts; Can effectively enhance productivity, cost-saving.
Connection bracket 2 is a pair, and a pair connection bracket 2 symmetry is located on crossbeam 1; Particularly, connection bracket 2 with line of centers in the middle part of crossbeam 1 for symmetric line symmetry is located on crossbeam 1; Connection bracket 2 is uniform force when crossbeam collides, the protective action that can provide.
Crossbeam 1 is rectangular square tube, and outside crossbeam 1, the bending to the inside of end, two ends forms bending part 7; Rectangular square tube inward at both ends lateral bend, effectively avoids sharp-pointed protrusion to damage; And uniform force during the higher collision of rectangular square tube intensity, the protective action that can provide.
Bending part 7 symmetry is located on crossbeam 1; Bending part 7 for symmetric line symmetry is located on crossbeam 1 two ends, further improves the structural strength of crossbeam 1 with line of centers in the middle part of crossbeam 1.
Connection bracket 2 and crossbeam 1 weld; The front lower portion fail-safe structure that rectangular square tube and two connection brackets 2 are welded, structural strength is good.
Connection bracket 2 comprises the contiguous block 5 be connected with crossbeam 1, and contiguous block 5 top is provided with the mounting hole of hold-down bolt 3, and contiguous block 5 top exceeds crossbeam 1, and contiguous block 5 is provided with the through hole 6 communicated with mounting hole; Such contiguous block 5 is box-like structure, ensures that crossbeam has enough supports under intense impact, can increase the anti-bending strength of crossbeam under the prerequisite of equal section width.The top that contiguous block 5 exceeds crossbeam 1 is connected by bolt 3 with truck frame 4 lower aerofoil, convenience quick for installation; Through hole 6 is convenient to the operation of tightening bolt 3 and unclamping, and improves assembling and dismounting convenience further, improves efficiency of assembling, easy accessibility.
Bolt 3 is connected with the project-welding nut that truck frame 4 lower aerofoil welds, and is easy for installation and removal.
Truck front lower portion fail-safe structure, not only structural strength is good, the protective effect that can provide for truck front lower portion, and connection bracket 2 is connected with vehicle frame 4 lower aerofoil by bolt 3, easy for installation, and is convenient to dismounting; Can effectively enhance productivity, cost-saving.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out, all within protection domain of the present utility model.
