The invention relates to a support frame of an automobile forecabin and the automobile forecabin applying the same, aiming at enhancing the lateral rigidity of the automobile forecabin so as to improve the transversely swinging mode of the automobile forecabin and enhancing the NVH (Noise Vibration and Harshness) property of an automobile. The support frame of the automobile forecabin comprises a base, a left connecting rod and a right connecting rod, wherein the left connecting rod and the right connecting rod are respectively connected at both sides of the base; the end parts of the left connecting rod and the right connecting rod are provided with bolt holes; the base of the support frame of the automobile forecabin is fixed on a front baffle plate of the automobile forecabin; the left connecting rod is connected with a shock absorber bearing positioned at the left side of the automobile, and the right connecting rod is connected with a shock absorber bearing positioned at the right side of the automobile. The support frame of the automobile forecabin and the automobile forecabin applying the same have simple structure and lower cost, and is easy for manufacture and realization; in addition, the connecting rods combine the front baffle plate with a stiffening beam into a shape similar to a tripod so as to convert the bending rigidity of the stiffening beam into the compressive rigidity of the connecting rods, therefore the lateral rigidity of the forecabin is effectively enhanced, the mode of the forecabin is improved, and the NVH property of the integral automobile is enhanced.
Description
Technical field
The invention belongs to field of automobile, specially refer to a kind of automobile front chamber support and use the automobile front chamber of this support.
Background technology
Mode, rigidity are the key factors that influences vehicle body NVH performance, and mode, the vehicle body that rigidity property is good can not only reduce vibration and noise, can also avoid the fatigue problem that causes because of vibration.Along with the raising that automotive performance is required, to the requirement of body mode, rigidity also in continuous lifting.And the annexation between the vehicle body sheet metal component be connected fiduciary level and directly have influence on body mode, rigidity.Front deck is used for settling important assemblies such as automotive engine, change-speed box, steering swivel system, storage battery as the vehicle body important component part, and these assembly quality are bigger to the influence of front deck mode.According to the dynam equation of motion:
In the formula, m, c and k are respectively quality, damping coefficient and stiffness coefficient, and x (t) is the displacement of object, and f (t) is the power that is applied on the object.Because of the real system damping ratio seldom greater than 10%, so ignore damping influence, the system undamped natural frequency of a mechanical system of obtaining is:
Because of the quality m of inner each branch unit of front deck is bigger, improve front deck model frequency w, just must improve front deck rigidity k.And front deck and the be connected quality of gusset at the automobile A column place directly influence front deck rigidity k.At present, strength beam on the front deck wheel cover (shotgun) and A post weld together, longer at their vertical direction connection sides, vertical stiffness is higher relatively, and narrow relatively in side direction (being Width), lateral rigidity is lower.Front deck yaw model frequency is generally lower like this, is easy to generate resonance, influences car load NVH performance.
Summary of the invention
First purpose of the present invention is to propose a kind of automobile front chamber support, increasing the lateral rigidity of automobile front chamber, thereby improves the yaw mode of automobile front chamber, improves the NVH performance of automobile.
Automobile front chamber support of the present invention is made up of base, left pipe link and right pipe link, and described left pipe link, right pipe link are connected to the both sides of base, and the end of left pipe link, right pipe link is provided with bolt hole.
Second purpose of the present invention is the automobile front chamber that proposes to use above-mentioned automobile front chamber support.
In automobile front chamber of the present invention, the base of front deck support is fixed on the front apron of automobile front chamber, and left pipe link is connected with the shock absorber bearing in automobile left side, and right pipe link is connected with the shock absorber bearing on automobile right side.
According to mechanics principle, rod member is subjected to curved lower than the rigidity of tension or pressure, above-mentioned left pipe link, right pipe link link to each other with strength beam by shock absorber bearing, like this, left side pipe link, right pipe link are combined into front apron, strength beam the shape of an approximate spider, can change into the bending stiffness of strength beam the tension and compression rigidity of left pipe link, right pipe link, thereby effectively improve the lateral rigidity of front deck.
Angle between described left pipe link, the right pipe link is the obtuse angle, can to greatest extent the bending stiffness of strength beam be changed into the tension and compression rigidity of left pipe link, right pipe link.
Described base is made up of base plate and the connecting panel that is vertically fixed on the base plate, and described left pipe link, right pipe link are by being bolted to the both sides of connecting panel.When mounted, can base plate be welded on the front apron of automobile front chamber earlier, and then utilize bolt left side pipe link, right pipe link, assemble up convenient like this.
Described base plate and connecting panel are bent into by sheet metal component, and be easy to process, in light weight.
Described base plate also links to each other by brace panel with connecting panel, and described brace panel is vertical with base plate, connecting panel respectively, with the rigidity of reinforced company's fishplate bar, avoids connecting panel to deform.
For expendable weight when guaranteeing rigidity, improve oil consumption, described left pipe link, right pipe link are made by hollow steel pipe.
Automobile front chamber support of the present invention and use that the automobile front chamber of this support is simple in structure, cost is lower, be easy to make and realize can effectively improve the lateral rigidity of front deck, improves front deck mode, improves car load NVH performance.
Description of drawings
Fig. 1 is the structural representation of automobile front chamber support of the present invention;
Fig. 2 is the structural representation of automobile front chamber of the present invention.
The specific embodiment
Describe the present invention in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, the automobile front chamber support of present embodiment is made up of base 1, left pipe link 2 and right pipe link 3, base 1 is made up of base plate 4 and the connecting panel 5 that is vertically fixed on the base plate 4, is welded with brace panel 6 between base plate 4 and the connecting panel 5, and brace panel 6 is vertical with base plate 4, connecting panel 5 respectively; A left side pipe link 2, right pipe link 3 are made by hollow steel pipe, and by being bolted to the both sides of connecting panel 5, the angle between left pipe link 2, the right pipe link 3 is the obtuse angle; The end of left side pipe link 2, right pipe link 3 is provided with bolt hole 7.
As shown in Figure 2, the structure of the automobile front chamber of the above-mentioned automobile front chamber support of present embodiment is as follows: the base 1 of front deck support is fixedly welded on the front apron 8 of automobile front chamber, left side pipe link 2 is connected with the shock absorber bearing 9 in automobile left side, and right pipe link 3 is connected with the shock absorber bearing 10 on automobile right side.
