Abstract
The utility model discloses a connecting device of an automobile chassis subframe and an automobile body. The connecting device comprises a reverse-T shaped nut socket and is characterized in that the upper end part of the nut socket is provided with a step, the bottom of the nut socket is provided with an inner screwed hole, the nut socket is fixedly connected with a frame structure of the automobile body, and the inner screwed hole arranged at the bottom of the nut socket is connected with the automobile chassis subframe in a matching way. The utility model has the advantages that since the device is fixedly connected with the frame structure of the automobile body with three layers, the installation point of an automobile subframe and the automobile body is added, so that the maximum load of the device is increased, so as to meet the requirement that the automobile subframe bears larger impact is met and solve the problem that the strength of the installation point of the automobile subframe and the automobile body is weak.
Description
Technical field
The utility model relates to automobile component, is specifically related to the connecting device of a kind of car chassis subframe and car body.
Background technology
Now, the auto-industry fast development, more and more higher to the various performance requriementss of automobile.Automobile accessory frame is one and closes very much heavy parts, its body structure of being attached the zone is had higher requirements, so the pairing car body mounting structure design of subframe just seems particularly important.Subframe generally is the connection mode that adopts bolt and nut with being connected of car body, and this zone should comprise nut and two factors of subframe attachment face at least generally speaking.It is project-welding nut that the simplest form of nut is installed, but this nut strength is very poor, and this stressed bigger parts of chassis auxiliary frame be can't bear the heavy load.Second kind is nutplate, is shaped as square, the about 30mm of the length of side, thickness 5mm.And join a nut box to it, the two is welded together, welded together with car body again by the protection weldering.If expected value is less demanding, the intensity of this installation nut can satisfy A substantially, the installation requirements of B level and compact sedan.But for C level and more premium-quality car, the suffered impulsive force of subframe is bigger.This nutplate and bolt be connected only 5mm of length, if periphery does not have good car body assist additional strengthening, the expected value that the mounting structure of this form just may the out of reach requirement.
Summary of the invention
The purpose of this utility model provides the connecting device of a kind of car chassis subframe and car body, its intensity height, can satisfy the requirement that automobile accessory frame bears greater impact power.
The connecting device of a kind of car chassis subframe described in the utility model and car body, comprise the ut socket that is inverse-T-shaped, it is characterized in that: the upper end of ut socket is provided with a step, the bottom is provided with internal thread hole, ut socket is captiveed joint with body frame structure, and the internal thread hole and the car chassis subframe that are located at the ut socket bottom are connected.
The connecting device of described a kind of car chassis subframe and car body, its described body frame structure is down the skeleton longeron of " U " shape by section, that section is " U " shape and be the inferior reinforcement that " U " shape and both sides outer wall and inwall bottom, main reinforcement both sides be close to main reinforcement and section that skeleton longeron inwall is close to and form, middle part on the skeleton longeron is provided with and cooresponding first mounting hole of automobile accessory frame, middle part on main reinforcement is provided with and cooresponding second mounting hole of automobile accessory frame, and the middle part on inferior reinforcement is provided with and the cooresponding via hole of automobile accessory frame; Be located at the ut socket bottom and be connected with main reinforcement, the internal thread hole of ut socket bottom is corresponding concentric with first mounting hole and second mounting hole, and the step of ut socket upper end passes the via hole and the captive joint at middle part above time reinforcement.
The utility model is compared with prior art and is had the following advantages: owing to captive joint with the body frame structure with three layers, thereby increased the attachment point of automobile accessory frame and car body, making it get the maximum load that can bear increases, the requirement that automobile accessory frame bears greater impact power be can satisfy, automobile accessory frame and car body attachment point intensity problem on the weak side solved.

Fig. 1 is the structural representation of body frame structure.
Fig. 2 is the scheme drawing that the utility model and body frame structure are connected.
Fig. 3 is the block diagram that the utility model and body frame structure are connected.
The specific embodiment
Referring to Fig. 2 and a kind of car chassis subframe shown in Figure 3 and the connecting device of car body, comprise the ut socket 14 that is inverse-T-shaped, the upper end of ut socket is provided with a step, the bottom is provided with internal thread hole, ut socket is captiveed joint with body frame structure, and the internal thread hole and the car chassis subframe that are located at the ut socket bottom are connected.
That skeleton longeron 11, the section that is down " U " shape by section referring to the described body frame structure of Fig. 1 is " U " shape and be the inferior reinforcement 13 that " U " shape and both sides outer wall and inwall bottom, main reinforcement both sides be close to main reinforcement 12 and section that skeleton longeron inwall is close to and form, middle part on skeleton longeron 11 is provided with and cooresponding first mounting hole 21 of automobile accessory frame, middle part on main reinforcement 12 is provided with and cooresponding second mounting hole 22 of automobile accessory frame, and the middle part on inferior reinforcement 13 is provided with and the cooresponding via hole 23 of automobile accessory frame; Being located at ut socket 14 bottoms is connected with main reinforcement 12, the internal thread hole of ut socket 14 bottoms is corresponding concentric with first mounting hole 21 and second mounting hole 22, and the step of ut socket 14 upper ends passes the via hole 23 and the captive joint at middle part above time reinforcement 13.
During installation, main reinforcement 12 is at first welded together with ut socket 14 usefulness CO2 protection weldering, and makes the internal thread hole of ut socket 14 concentric with second mounting hole 22 on the main reinforcement; Then, again that main reinforcement 12 is welded together with skeleton longeron 11, to make first mounting hole 21 above the skeleton longeron 11 concentric equally with the internal thread hole of ut socket; At last; inferior reinforcement 13 is welded together by passing through the protection weldering with main reinforcement 12 and ut socket; skeleton longeron 11, main reinforcement 12, inferior reinforcement 13 and ut socket 14 are welded into an integral body; thereby increased the attachment point of automobile accessory frame and car body, made it get the maximum load that can bear and increase.
