Abstract
The utility model discloses a enclose before driver's cabin, enclose the baffle before being equipped with a plurality of mounting holes, enclose the upper and lower both ends of baffle before and install respectively and enclose the bottom end rail, left riser and right riser are installed respectively to preceding left and right both sides of enclosing the baffle, it has left longeron and right longeron to enclose the bottom end rail both ends before and weld respectively, the upper end of left side longeron and right longeron all links to each other with preceding entablature lower extreme of enclosing, enclose entablature, left longeron, right longeron before and enclose the bottom end rail and weld into integral type frame, left side longeron and right longeron inboard all are equipped with and pass the power support. The utility model discloses can make the structure lightweight, can guarantee structural strength and rigidity again, processing, manufacturing are easy moreover.
Description
Technical field
The utility model relates to automobile cab technical field, is specially a kind of cab front wall.
Background technology
Body forward structure is the important component part of vehicle body, and its exterior component is the embodiment of car load image characteristics, and each functor in face shield in front wall is intensive, make front wall in whole operator's compartment body drawing in consequence.
Front closed structure will be taken into account following numerous functional requirement: because of the functor of installing in front wall a lot, make the hole opened on front coaming plate a lot, therefore before requiring, coaming plate will have good rigidity, and much cabin front suspension is arranged in front wall, so closed structure has good intensity before requiring again; And the front collision of vehicle security and pendulum collision require front wall to have certain energy absorption performance for assurance personnel living space.
Existing cab front wall mainly contains following two kinds:
L, plank frame: this structure is by inside and outside two-layer thicker sheet metal forming, then weld together, although the front wall strength and stiffness of plank frame are better, but weight is heavier, and owing to being to stamp out muscle with 2 large plates, close postwelding and form " beam chamber ", so moulding is all more difficult, all higher to the tonnage demand of punch process and equipment thereof.At present domestic mechanical process capacity is all difficult to catch up with, so adopt with it seldom at domestic car, in Europe, is just that car adopts on as vehicles such as Reynolds and benzs.
2, girder structure: this structure is welded by front grit and front wall, relatively plank frame front wall and the amount of overstating is lighter.Before traditional beam type, closed structure is generally welded by lower and upper cross-member and front surrounding baffle, but, due to numerous maintenance functors of installing in front wall, make the hole opened on front coaming plate a lot, and cabin front suspension is arranged in front wall, make front wall will bear very large bending moment and endurance failure, cause front coaming plate and front wall cross sill often to break, it is more that this structure adopts on Japanese car.
Summary of the invention
As can be seen here, the defect that exists Heavy Weight, difficult forming and front coaming plate often to break in prior art.
Therefore, the deficiency existing in order to overcome prior art, the utility model, for the technical matters that will solve provides a kind of cab front wall, can make structure lightweight, can guarantee structural strength and rigidity again, and processing, easy to manufacture.
For solving the problems of the technologies described above, the utility model cab front wall comprises the front surrounding baffle that is provided with a plurality of mounting holes, described front surrounding baffle upper/lower terminal is separately installed with front wall entablatrance and front wall cross sill, described front surrounding baffle arranged on left and right sides is separately installed with left riser and right riser, described front wall cross sill two ends are welded with respectively left longeron and right vertical beam, the upper end of described left longeron and right vertical beam is all connected with front wall entablatrance lower end and makes front grit form tower structure, and described left longeron and right vertical beam inner side are equipped with force transfer bracket.
As the further improvement of the above-mentioned cab front wall of the utility model, the front surrounding baffle at described mounting hole edge is provided with brace panel.
The beneficial effects of the utility model are as follows: the mounting hole place on front surrounding baffle is provided with the brace panel of each functor, guaranteed to be arranged on the installation strength of the functor on front surrounding baffle, and the layout of whole brace panel makes the stressed very even of front surrounding baffle, eliminate high stress point, stopped breaking of front surrounding baffle; Front wall entablatrance, left longeron, right vertical beam and front wall cross sill form tower structure, and the power passing over suspending is delivered to whole operator's compartment, effectively reduces the stress of the installation portion that suspends, and has reduced the cracking of front grit; The force transfer bracket that install left longeron and right vertical beam inner side reduce the Steering gear that is arranged in front wall and meter system to navigating mate burst, guarantee navigating mate and passenger's living space; Whole front wall structural weight is lighter, suitable with traditional girder structure weight.
Read by reference to the accompanying drawings after the detailed description of the utility model embodiment, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment of the present utility model, the utility model cab front wall is made the following instructions.
Embodiment: the utility model comprises the front surrounding baffle 1 that is provided with a plurality of mounting holes 10, front surrounding baffle 1 upper/lower terminal is separately installed with front wall entablatrance 2 and front wall cross sill 3, front surrounding baffle 1 arranged on left and right sides is separately installed with left riser 4 and right riser 5, front wall cross sill 3 two ends are connected with right vertical beam 7 with left longeron 6 respectively, wherein the shape of left longeron 6 and right vertical beam 7 can be L-type, and the upper end of left longeron 6 and right vertical beam 7 is all connected with front surrounding baffle 1 lower end.Front wall entablatrance 2, front wall cross sill 3, left longeron 6 and right vertical beam 7 are welded into tower structure; This tower structure plays the effect of power transmission; And general, safety is good; Front surrounding baffle 1, left riser 4 and right riser 5 are welded into an integral body, then the tower structure of above-mentioned welding are installed to welding.
The front surrounding baffle 1 at mounting hole 10 edges is provided with brace panel 9, guaranteed to be arranged on the installation strength of the maintenance functor in front wall, and the layout of whole brace panel makes the stressed of front coaming plate evenly disperse concentrated stress, has greatly reduced the risk that front coaming plate breaks.Left longeron 6 and right vertical beam 7 inner sides are equipped with force transfer bracket 8, the power of front pendulum and front collision is passed to underframe longitudinal member, effectively reduce the Steering gear be arranged in front wall and meter system to navigating mate burst, guarantee navigating mate and passenger's living space, improved the safety performance of automobile.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
