Abstract
The utility model discloses a kind of commercial vehicle/comm..vehicle front anti-collision beam, comprise collision prevention girders body, described collision prevention girders body is divided into upper and lower, and wherein upper and lower is respectively collapse structure.The dashpot of darker cup depth is provided with in the middle of the rectangle buffer structure of described upper and lower.Described collision prevention girders body section width is 58.7mm, and cross-sectional length is 118.5mm.Described collision prevention girders body both sides are provided with mounting hole and install via hole.Described dashpot section width is 25mm.The cross section of described collision prevention girders body is enclosed construction.The utility model advantage is: by the version to front anti-collision beam, and dimensional parameters carries out brand-new design, improve the passive security performance of occupant, and the available protecting parts such as vehicle body, reduce cost.
Description
Technical field
The utility model relates to automobile collision preventing technical field, particularly a kind of commercial vehicle/comm..vehicle front anti-collision beam.
Background technology
Front anticollision beam of automobile is one of important spare part ensureing automotive SBC energy, and the developed countries such as China and America and Europe focus on automotive SBC energy more more.Good passive security performance, is more and more subject to the attention of user vehicle.Relative to manned vehicle, the curb mass of commercial vehicle/comm..vehicle is comparatively large, and front overhang is shorter, and these factors are all unfavorable to the collision safety performance of commercial vehicle/comm..vehicle, therefore just stricter to the requirement of commercial vehicle/comm..vehicle front anti-collision beam.
Under low speed collision condition to the basic demand of front anti-collision beam, the parts such as available protecting vehicle body; And under high-speed crash condition, can be implemented in collision process, impact force is disperseed to two longerons, and its rigidity is less than the rigidity of longeron, to play certain energy-absorbing function; Front anti-collision beam also plays an important role to rigidity of the vehicle simultaneously.Based on above-mentioned requirements, if adopt traditional one-board structure, then easily cause insufficient rigidity, the energy-absorbing function played in collision process is limited; If adopt thermoforming technology or ultra-high strength steel plate, easily cause rigidity excessive, energy-absorbing is not enough, increases cost simultaneously; If adopt aluminum alloy collision prevention girders, then high cost.
Summary of the invention
The utility model object is to solve the own constructional feature of commercial vehicle/comm..vehicle front anti-collision beam in prior art, and the defect of crashworthiness and self-strength deficiency, provides a kind of commercial vehicle/comm..vehicle front anti-collision beam, to solve problems of the prior art.
The utility model object is achieved through the following technical solutions: a kind of commercial vehicle/comm..vehicle front anti-collision beam, comprises collision prevention girders body, and described collision prevention girders body is divided into upper and lower, and wherein upper and lower is respectively collapse structure.The dashpot of darker cup depth is provided with in the middle of the rectangle buffer structure of described upper and lower.Described collision prevention girders body section width is 58.7mm, and cross-sectional length is 118.5mm.Described dashpot section width is 25mm.Described collision prevention girders body both sides are provided with mounting hole and install via hole.The cross section of described collision prevention girders body is enclosed construction.
The utility model has the advantage of: by the version to front anti-collision beam, dimensional parameters carries out brand-new design, improves the passive security performance of occupant; Under low speed collision condition, plasticity bending can not occur, and the available protecting parts such as vehicle body, reduce maintenance cost; Adopt roll-forming technology and high strength steel plate, closed cross section, while ensureing excellent bending stiffness, alleviates pts wt; By the optimization of sectional dimension parameter, under the prerequisite meeting vehicle performance requirement, avoid ultra-high strength steel plate, the use of thermoforming technology and aluminum alloy, reduces cost; Adopt the overall roll-forming technology of whole steel plate, avoid welded lap and welding sequence, there is good shop characteristic and loss of weight performance.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, Figure 2, the utility model provides a kind of commercial vehicle/comm..vehicle front anti-collision beam, comprise collision prevention girders body (1), described collision prevention girders body (1) is divided into top (2) and bottom (3), and its middle and upper part (2) and bottom (3) are respectively rectangle buffer structure.Described top (2) and the middle dashpot (6) being provided with darker cup depth of bottom (3) collapse structure.Described collision prevention girders body (1) section width is 58.7mm, and cross-sectional length is 118.5mm.Described dashpot (6) section width is 25mm.Described collision prevention girders body (1) both sides are provided with mounting hole (4) and install via hole (5).The cross section of described collision prevention girders body (1) is enclosed construction.
The utility model has the advantage of: by the version to front anti-collision beam, dimensional parameters carries out brand-new design, improves the passive security performance of occupant; Under low speed collision condition, plasticity bending can not occur, and the available protecting parts such as vehicle body, reduce maintenance cost; Adopt roll-forming technology and high strength steel plate, closed cross section, while ensureing excellent bending stiffness, alleviates pts wt; By the optimization of sectional dimension parameter, under the prerequisite meeting vehicle performance requirement, avoid ultra-high strength steel plate, the use of thermoforming technology and aluminum alloy, reduces cost; Adopt the overall roll-forming technology of whole steel plate, avoid welded lap and welding sequence, there is good shop characteristic and loss of weight performance.
