Abstract
The utility model provides an automobile auxiliary frame strengthening structure and an auxiliary frame with the same. Point load heavily stressed of the auxiliary frame can be effectively shared through the strengthening structure, the auxiliary frame is prevented from cracking, the stiffness of the auxiliary frame can be improved at the same time, and the manipulation performance of the whole automobile is improved. The automobile auxiliary frame strengthening structure comprises a body, the two ends of the body are in an arc shape, and bolt holes are formed in the body. The front end of the auxiliary frame with the automobile auxiliary frame strengthening structure is provided with a left control arm and a right control arm, the left control arm and the right control arm of the auxiliary frame are fixedly welded to the end portion of an arc board respectively, and the automobile auxiliary frame strengthening structure is fixedly connected with an automobile front longitudinal beam through bolts passing through the bolt holes. The automobile auxiliary frame strengthening structure and the control arms of the auxiliary frame form a sealed structure, the stiffness of the auxiliary frame is improved, and the improvement of the manipulating performance of the whole automobile is facilitated. Meanwhile, the load at the control arms of the auxiliary frame can directly passes through the front longitudinal beam to be transferred to an automobile body through the strengthening structure, and the auxiliary frame is prevented from cracking.
Description
Technical field
The utility model belongs to automotive field, specially refers to that a kind of automobile accessory frame is strengthened structure and with the subframe of this reinforcement structure.
Background technology
The vehicle chassis components such as the subframe of automobile is the important composition parts of car chassis system, and main effect is supporting suspension, turn to, suspend, reduce road excitation to the transmission of vehicle body, improve the NVH performance of car load, improve the coupling stiffness of suspension system.Subframe is subject to suspension, turn to the various load of power assembly system and affect, and therefore requires subframe to have enough rigidities of structure and intensity, to obtain good car load durability.Especially, subframe bears great load in the process of wheel hop and braking, for example, under damped condition, no matter be McPherson suspension or double wishbone suspension, nearly ten thousand newton's load all will be born by the point of connection place of Control arm and subframe, is easy to occur problems of crack.
Summary of the invention
The purpose of this utility model is to propose that a kind of automobile accessory frame is strengthened structure and with the subframe of this reinforcement structure, by this reinforcement structure, can share the stressed larger point load of subframe by actv., avoid subframe cracking, can promote the rigidity of subframe, improve the handling of car load simultaneously.
Automobile accessory frame of the present utility model is strengthened structure and is comprised body, and the two ends of described body are curved, and described body is provided with bolt hole.
Apply above-mentioned automobile accessory frame and strengthen the subframe of structure, the front end of this subframe is provided with left and right Control arm, key is that the left and right Control arm of described subframe is welded and fixed with the end of described arc respectively, and described automobile accessory frame is strengthened structure and fixed by the bolt through bolt hole and automobile front longitudinal beam.
The Control arm that automobile accessory frame is strengthened structure and subframe has formed an enclosed construction, has promoted the rigidity of subframe, is conducive to improve the handling of car load.The load at subframe Control arm place directly can be delivered on vehicle body by front side member by strengthening structure simultaneously, share the load of bearing in subframe original design, avoid subframe cracking.
Further, the body that described automobile accessory frame is strengthened structure consists of stripe board, two symmetrical arcs, and described bolt hole is arranged at the two ends of stripe board and the end of arc; Described stripe board, two arcs connect by the bolt through bolt hole.It is Split type structure that automobile accessory frame is strengthened to structure design, be conducive to the welding of arc, and when hold-down bolt, can realize the connection of stripe board, two arcs and automobile accessory frame simultaneously and strengthen being connected of structure and automobile front longitudinal beam, be to kill two birds with one stone.
Further, the bolt hole at described stripe board two ends is symmetrical arranged, and the bolt hole of every end is three, and arranges triangularity, reliable to guarantee to connect.
The Control arm of subframe reinforcement structure of the present utility model and subframe has formed the sub-circular of a sealing, and place is connected with front side member at stripe board bolt hole, being equivalent to has increased by two attachment points for subframe, actv. has promoted the rigidity of subframe, improve the handling of car load, and effectively avoided the problem of Cracking of subframe under large load working condition.
Accompanying drawing explanation
Fig. 1 is the structural representation that subframe of the present utility model is strengthened structure.
Fig. 2 is the structural representation of subframe of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and principle of work etc.
Embodiment 1:
As shown in Figure 1, the automobile accessory frame of the present embodiment is strengthened structure and is consisted of stripe board 1, two symmetrical arcs 2,3, and the end of the two ends of stripe board 1 and arc 2,3 is equipped with identical shaped bolt hole 4; Described stripe board 1, two arcs 2,3 are sheet metal component and are stamped to form, and connect by the bolt through bolt hole 4.The bolt hole 4 at described stripe board 1 two ends is symmetrical arranged, and the bolt hole 4 of every end is three, and arranges triangularity, reliable to guarantee to connect.
Fig. 2 is the subframe 5 of the above-mentioned automobile accessory frame reinforcement structure of application, the front end of this subframe 5 is provided with left and right Control arm 6,7, the left Control arm 6 of subframe is welded and fixed with the end of arc 2, right Control arm 7 is welded and fixed with the end of arc 3, and described automobile accessory frame is strengthened structure and fixed by the project-welding nut of the bolt through bolt hole 4 and automobile front longitudinal beam.
The left and right Control arm that automobile accessory frame is strengthened structure and subframe has formed an enclosed construction, has promoted the rigidity of subframe, is conducive to improve the handling of car load.The load at subframe Control arm place directly can be delivered on vehicle body by front side member by strengthening structure simultaneously, share the load of bearing in subframe original design, avoid subframe cracking.
