Description
Technical field
The utility model relates to the towing arm attachment point on auto body, and specifically, the utility model relates to a kind of vehicle body towing arm attachment point structure.
Background technology
When automobile travels on road, can run into the travel conditions of various complexity, as: accelerate, turn, brake, cross hole etc.Under these driving cycles, road surface can produce very large impact load to wheel, and these load can be delivered to vehicle body by suspension.Wherein, Z-direction impact load is mainly born by spring perch and damper base, and the impact load of X and Y-direction is mainly born by vehicle body towing arm attachment point.So if unreasonable structure herein, intensity, rigidity are inadequate, gently affect travelling comfort, heavy make vehicle body cracking, structural failure.At present, in order to strengthen the strength and stiffness of vehicle body towing arm attachment point, be mainly to promote by increasing the form of adapter plate and brace panel, but it is excessive also to exist brace panel, preponderance, promotes the problems such as less to local strength and stiffness.
Utility model content
The utility model provides a kind of vehicle body towing arm attachment point structure, and object is to improve the strength and stiffness of the towing arm attachment point on auto body.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of vehicle body towing arm attachment point structure, comprise sill strip, floor side member and towing arm adapter plate, towing arm adapter plate is connected with floor side member with sill strip, towing arm adapter plate is provided with towing arm attachment point, and described towing arm attachment point is provided with four on described towing arm adapter plate.
Described towing arm adapter plate is U-shaped structure, and the both ends of towing arm adapter plate are provided with the flange for being connected with floor side member with described sill strip.
Vehicle body towing arm attachment point structure also comprises the nut seat adapter plate being located on described towing arm adapter plate and the nut seat arranging at described towing arm attachment point place, nut seat one end is connected with towing arm adapter plate, the other end is connected with nut seat adapter plate, nut seat adapter plate and towing arm adapter plate connect and compose box-like structure, and nut seat is provided with the centre hole coaxial with towing arm attachment point.
Described nut seat adapter plate is provided with flange, and nut seat adapter plate is connected with described towing arm adapter plate by flange.
The utility model adopts technique scheme, compared with prior art, this vehicle body towing arm attachment point structure is four by increasing the number of the towing arm attachment point on towing arm adapter plate, thereby can form at 4 to towing arm fixes, 4 fixing moments of torsion of X and the generation of Y-direction impact load that can make are well by four attachment point balances, it is stressed evenly reasonable to guarantee, effectively promotes the strength and stiffness of towing arm attachment point structure; And vehicle body towing arm attachment point place is simple and compact for structure, lightweight, be applicable to light-weight design.
Accompanying drawing explanation

Mark in above-mentioned figure is: 1, sill strip; 2, floor side member; 3, towing arm adapter plate; 4, nut seat adapter plate; 5, nut seat; 6, towing arm attachment point; 7, the first flange; 8, the second flange; 9, contact surface on nut seat; 10, nut seat bottom.
The specific embodiment
As shown in Figures 1 to 6, a kind of vehicle body towing arm of the utility model attachment point structure, comprise sill strip 1, floor side member 2 and towing arm adapter plate 3, towing arm adapter plate 3 is connected with floor side member 2 with sill strip 1, towing arm adapter plate 3 is provided with towing arm attachment point 6, towing arm attachment point 6 is provided with four on towing arm adapter plate 3, thereby can form at 4 to towing arm, fixes.Towing arm X and Y-direction impact load are passed to vehicle body towing arm attachment point 6 places by bracket of trailing arm, due to the height between bracket of trailing arm and longeron attachment point, make the impact load of X and Y-direction produce moment of torsion, if fixing, wherein have the load of a point to be obviously greater than other bright spots at 3.But the strength and stiffness of three attachment points are about the same herein, if load maximum point can meet requirement of strength, the structure of remaining 2 can be obvious excessively strong, cause structure waste, otherwise load maximum point there will be cracking.4 fixing, can make the moment of torsion of X and the generation of Y-direction impact load well by four attachment point balances, and it is stressed evenly reasonable to guarantee, effectively promotes the strength and stiffness of towing arm attachment point structure; And vehicle body towing arm attachment point place is simple and compact for structure, lightweight, be applicable to light-weight design.
Specifically, towing arm adapter plate 3 is U-shaped structure, towing arm attachment point 6 is positioned on the middle part plate body of towing arm adapter plate 3, the end of two side plates that towing arm adapter plate 3 stretches out is provided with the first flange 7 for being connected with floor side member 2 with sill strip 1, the first flange 7 is connected with sill strip 1 solder joint with floor side member 2, the little effect of area is large, saves material, expendable weight.
In order better to strengthen the strength and stiffness of attachment point, this vehicle body towing arm attachment point structure also comprises the nut seat adapter plate 4 being located on towing arm adapter plate 3 and the nut seat 5 arranging at four towing arm attachment points, 6 places.Nut seat adapter plate 4 is arranged on towing arm adapter plate 3 belows, and nut seat adapter plate 4 and towing arm adapter plate 3 connect and compose the box-like structure of sealing.It is inner that nut seat 5 is positioned at this box-like structure, freezes and be connected with towing arm adapter plate 3 in nut seat upper end, freezes and be connected with nut seat adapter plate 4 in nut seat bottom 10, makes towing arm adapter plate 3 and nut seat adapter plate 4 form an integral body.Like this, nut seat 5, with regard to the bearing column in resemble construction, can play good intermal force, and the power of towing arm attachment point 6 is shared on each adapter plate uniformly, thereby has also promoted the strength and stiffness of vehicle body towing arm attachment point structure.
Nut seat adapter plate 4 is U-shaped structure, and the end of the middle part plate body of nut seat adapter plate 4 and two side plates that stretch out is equipped with the second flange 8, and nut seat adapter plate 4 is connected with towing arm adapter plate 3 solder joints by the second flange 8 of four sides.The middle part plate body of nut seat adapter plate 4 is provided with the through hole that allows nut seat bottom 10 stretch out.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
