Abstract

The invention discloses a reinforcement structure for a front sub-frame. The reinforcement structure is characterized in that the reinforcement structure is as follows: two control arm liner bushing supports are connected with two connecting points of the front sub-frame through reinforcement rods. Due to the adoption of the structure, the reinforcement structure has the following advantages: 1) the reinforcement structure can increase integral rigidity, in particular to bending rigidity and torsional rigidity of the sub-frame, which provides convenience for improving vehicle ride comfort; 2) the volume is small, the spatial arrangement is relatively convenient, and the reinforcement structure is favorable for reducing weight on the premise of meeting strength; and 3) the cost is lower, and the mounting and the detachment are convenient.

Description

A kind of additional strengthening of fore sub frame
Technical field
The present invention relates to the fore sub frame of automobile, particularly a kind of additional strengthening of fore sub frame.
Background technology
The fore sub frame of automobile is mainly used in parts such as deflector, Control arm, engine mounting, stabilizer rod are installed, and is generally lining with vehicle body to be connected, and subframe encourages for ground-surface when vehicle ' and plays certain buffer action, and has strengthened the chassis rigidity.
When automobile sport because vertically, side direction and vertical load can act on each point of connection of subframe, and the single-piece rigidity and the intensity of subframe is had certain requirement.Automobile turn, glancing impact because butterfly-like fore sub frame structure two ends are wide, intermediate narrower makes the rigidity of middle part less than two ends, the distortion of rigidity gradual change position can be bigger, causes stress concentration easily in the round-corner transition zone.Equally, under the jumping operating mode was hung down in single-wheel, subframe mainly bore flexion torsion load, and under bigger moment of flexure or torsional interaction, the subframe insufficient rigidity also can cause structure partial to destroy.Can reduce automobile ride comfort in the process of moving if the rigidity of subframe is less.
To above-mentioned problem, it is the problem that prior art need solve that the rigidity of further strengthening fore sub frame need not to increase too much cost again.
Summary of the invention
Technical matters to be solved by this invention is, a kind of additional strengthening of fore sub frame is provided, to reach the purpose of not only strengthening the rigidity of fore sub frame but also need not to increase too much productive costs.
For solving the problems of the technologies described above; Technical scheme of the present invention is; A kind of additional strengthening of fore sub frame is characterized in that: described additional strengthening is that two Control arm lining supports adopt stirrup to be connected with two point of connection of fore sub frame, thereby the rigidity of fore sub frame is strengthened.
The edge of the end of described fore sub frame and Control arm lining support is respectively equipped with bolt hole, and the two ends of stirrup are provided with bolt hole; Stirrup is fixed through the end of bolt and fore sub frame and the edge of Control arm lining support.
Described stirrup is horizontal arrangement.
Described stirrup is the hollow circular-tube structure.
The overall diameter of described stirrup is 22mm, and wall thickness is 3mm.
A kind of additional strengthening of fore sub frame, owing to adopt said structure, this additional strengthening has following advantage: 1, increased the subframe integral rigidity, especially bending and torsional stiffness help to improve automobile ride; 2, volume is little, and spatial destribution is comparatively convenient, is satisfying under the prerequisite of intensity, helps loss of weight simultaneously again.3, cost is lower, and Assembly &Disassembly is convenient.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation;
Fig. 1 is the structural representation of the additional strengthening of a kind of fore sub frame of the present invention;
Fig. 2 is the local structure scheme drawing of the additional strengthening of a kind of fore sub frame of the present invention;
Fig. 3 is the section-drawing of the additional strengthening stirrup of a kind of fore sub frame of the present invention;
In Fig. 1-3,1, Control arm lining support; 2, fore sub frame; 3, stirrup.
The specific embodiment
The present invention seeks to improve subframe integral rigidity and intensity, help to reduce subframe, can improve the ride comfort of automobile simultaneously because of rigidity or undercapacity influence the risk of automotive performance.
The present invention is that two Control arm lining supports 1 adopt stirrup 3 to be connected with two point of connection of fore sub frame 2, thereby the rigidity of fore sub frame is strengthened.The edge of the end of fore sub frame 2 and Control arm lining support 1 is respectively equipped with bolt hole, and the two ends of stirrup 3 are provided with bolt hole; Stirrup 3 is fixed through the end of bolt and fore sub frame 2 and the edge of Control arm lining support 1.
The present invention is used for assembling with the bolt hole of stirrup 3 ends at fore sub frame 2 ends and Control arm lining support 1 edge placement one bolt hole.Stirrup 3 horizontal arrangement are in the subframe front end, and in order to alleviate rod member weight, stirrup can adopt the channel-section steel structure; Or adopt the hollow circular-tube structure, according to mechanical knowledge, adopt the hollow circular-tube texture ratio better; Stirrup 3 is a hollow structure, preferred overall diameter 22mm, wall thickness 3mm.Under operating modes such as braking, the jumping of hanging down, additional strengthening can effectively reduce the design deficiency that the subframe flexion torsion brings, and improves automotive performance at vehicle.
Concrete shown in Fig. 1-3, the present invention includes Control arm lining support 1, fore sub frame 2, stirrup 3.Fore sub frame 2 ends and Control arm lining support 1 edge placement one bolt hole, a bolt hole is respectively arranged at the two ends of stirrup 3, is used for assembling with the anterior two ends of subframe, stirrup 3 is arranged horizontally during assembling.For expendable weight, satisfy requirement of strength simultaneously, stirrup can adopt the channel-section steel structure, or adopts the hollow circular-tube structure, adopts the hollow circular-tube structure among the present invention.Stirrup 3 is installed on the subframe front end through the bolts at two ends hole horizontal.Be connected as a whole with subframe.When subframe receives pavement loading, can effectively improve the integral rigidity of subframe, improve automotive performance through stirrup 3.Stirrup 3 adopts circular tube structures, and this structure can be according to the different mining of actual vehicle with the different diameters and the pipe of thickness.Further, also can adopt the stirrup structure of other cross sectional shapes as required.
The present invention has increased the subframe integral rigidity, and especially bending and torsional stiffness have remedied the subframe undercapacity that causes because of under the road conditions such as the jumping of turning, brake, hang down, and helped to improve automobile ride.Because stirrup 3 adopts hollow rod member, volume is little, and spatial destribution is comparatively convenient, is satisfying under the prerequisite of intensity, helps loss of weight simultaneously again, and is obvious for the effect of raising subframe rigidity, and cost is lower, and Assembly &Disassembly is convenient.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted technical scheme of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
