Abstract
The utility model discloses a connection structure of a second vehicle frame, which comprises a second vehicle frame body. The utility model is characterized in that a plurality of sleeves using a central line as a level position is arranged on the second vehicle frame body; and the sleeves passing through the sleeves through bolts are fixed to a connection structure of a vehicle body. As the above structure is used, the utility model has the advantages of that the harmony motion of the second vehicle frame and a suspension frame is realized, and the operating stability of the whole vehicle is improved; the libration of the second vehicle frame and the vehicle body on the level direction and the vertical direction is reduced, and the NVH performance of the whole vehicle is improved; and the structure is simple, and the production cost is low.
Description
Technical field
The utility model relates to the field, chassis of automobile, particularly a kind of sub-frame connecting structure.
Background technology
On automobile, subframe is the vitals that connects suspension and vehicle body.For fore sub frame, it is also bearing the effect of carrying dynamic assembly.In the vehicle operating process, come from ground-surface application force and vibration meeting propagated along tire-Control arm-subframe-vehicle body, finally be fed back to the motion of vehicle body and occupant's subjective feeling.The independence of subframe structure can guarantee that the connection structure design of subframe and suspension can satisfy the various complicated requirement of suspension, thereby guarantees good road-holding property.Rubber element between subframe and suspension, subframe and the vehicle body in addition, also well decayed vibration and noise that the road surface is transmitted.In view of the vital function of subframe, it is used also more and more widely.
Present technology mainly by between subframe and body contact point, install additional with elastomeric fabricated section alleviate because of vehicle collision produce to occupant's injury with the protection member; traditional subframe all is in the vertical direction bolt and a body contact; although the rubber original paper is arranged in the installing sleeve; but after the bolted, its vibration damping motion is restricted.Owing to be that 4 vertical directions are fixed, therefore subframe can not also just can't improve road-holding property with the suspension coordinated movement of various economic factors at the XY in-plane moving in addition, for traditional subframe, and, bolt is vertically, passes bolt hole subframe is linked to each other with vehicle body.Although rubber element is installed in the sleeve, after the bolted, the cushioning performance of rubber element can only be embodied on the plane motion, and is difficult to embody in the more serious vertical direction of vibration.Provide a kind of later-model sub-frame connecting structure reaching and the suspension coordinated movement of various economic factors, and realize that its vibration damping in vertical direction is the problem that prior art need solve.
The utility model content
Technical problem to be solved in the utility model is, a kind of sub-frame connecting structure is provided, and reaching and the suspension coordinated movement of various economic factors, and realizes its purpose at the vibration damping of vertical direction.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of sub-frame connecting structure, comprise the subframe body, it is characterized in that: described subframe body is provided with the sleeve that a plurality of line of centerss are level attitude, sleeve passes sleeve by bolt and the body contact structure is fixed, thereby realizes fixing and having reached the coordinated movement of various economic factors with suspension of subframe and vehicle body.
Be provided with rubber bush in the described sleeve, thereby alleviate the vibration of subframe and vehicle body in vertical direction.
Described body contact structure is two fixed plates, lays respectively at the two ends of sleeve, thereby guarantees subframe and the fixing stability of vehicle body.
Described bolt is fixed with nut after passing body contact structure and sleeve, thereby guarantees bolted stability and dismantled and assembled property.
A kind of sub-frame connecting structure, owing to adopt said structure, this connection structure has the following advantages: 1, realize the coordinated movement of various economic factors of subframe and suspension, improve the road-holding property of whole automobile; 2, alleviate subframe and vehicle body in the horizontal direction with vertical direction on vibration, improve the NVH performance of whole automobile; 3, simple in structure, productive costs is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of a kind of sub-frame connecting structure of the utility model;
In Fig. 1,1, the subframe body; 2, body contact structure; 3, bolt; 4, sleeve; 5, nut.
The specific embodiment
As shown in Figure 1, a kind of sub-frame connecting structure, comprise subframe body 1, it is characterized in that: described subframe body 1 is provided with the sleeve 4 that a plurality of line of centerss are level attitude, it is fixing with body contact structure 2 that sleeve 4 passes sleeve 4 by bolt 3, thereby realize fixing and having reached the coordinated movement of various economic factors with suspension of subframe and vehicle body.
Be provided with rubber bush in the described sleeve 4, thereby alleviate the vibration of subframe and vehicle body in vertical direction.
Described body contact structure 2 is two fixed plates, lays respectively at the two ends of sleeve 4, thereby guarantees subframe and the fixing stability of vehicle body.
Described bolt 3 passes body contact structure 2 and sleeve 4 backs are fixing with nut 5, thereby guarantees bolted stability and dismantled and assembled property.
In concrete illustrating, X, Y, three directions of Z have been defined.Wherein directions X is the fore-and-aft direction of vehicle, and Y is the left and right directions of vehicle, and the Z direction is the vertical direction of vehicle, just perpendicular to ground-surface direction.
Rear secondary frame for vehicle of the present utility model still is at 4 and body contact.For a bit, bolt 3 is to pass the sleeve 4 that is in the XY plane vehicle body and subframe are linked together.Keystone configuration of the present utility model is characterized as: subframe is to be connected by multiple spot bolt 4 with vehicle body, but the line of centers of each bolt hole is to be on the same approximately horizontal plane (XY plane), thereby for subframe can move, rubber bush provides possibility at Z to the effect of playing damped vibration; The direction of bolt hole center's line can be arbitrarily angled in the XY face, but no matter is what angle, and its purpose all is to guarantee that subframe when being subjected to the power that suspension transmits, satisfactory compliant motion can taking place, thereby help to improve vehicle handling and stability; In the sleeve 4 rubber element is installed, it is multiple different that the structure of rubber original paper and rigidity have, but its purpose all is to decay as much as possible to reach vibration on the Z direction of vehicle body from ground, thereby improve the NVH performance of vehicle.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
