Description

Front lower swing arm large shaft sleeve lower plate

Technical field

The utility model belongs to vehicular spare parts field, especially relates to a kind of front lower swing arm large shaft sleeve lower plate.

Background technology

Automobile lower suspension arm assembly, between auto body and wheel flutter, it is suspension main guide rod part, propelling rod effect can also be played, bear startup, braking, longitudinal force during turning and transverse force, it is one of major part determining vehicle performance, buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, decay the vibrations caused thus, to ensure that automobile can smoothly travel, on the other hand, vibration easily makes existing lower swing arm assembly weld and does not closely locate distortion, after long-time, lower swing arm there will be slight crack, affect the normal traveling of vehicle, reduce the safety that vehicle uses.

For improving the performance of lower swing arm assembly, the serviceability of each parts need be optimized, the performance of lower swing arm large shaft sleeve lower plate before such as improving, make it be weldingly connected with front lower swing arm large shaft sleeve upper plate, front lower swing arm large shaft sleeve stabilizer bar arm better, prevent because welding does not closely cause being out of shape and using the rear generation producing the situations such as slight crack.

Summary of the invention

In view of this, the utility model is intended to propose a kind of front lower swing arm large shaft sleeve lower plate, make it be weldingly connected with front lower swing arm large shaft sleeve upper plate, front lower swing arm large shaft sleeve stabilizer bar arm better, prevent because welding does not closely cause being out of shape and using the rear generation producing the situations such as slight crack.

For achieving the above object, the technical solution of the utility model is achieved in that

Front lower swing arm large shaft sleeve lower plate, comprise arcwall face and trapezoidal faces, described arcwall face minor face is connected with the short base of trapezoidal faces, and be provided with an elliptical aperture in the middle of arcwall face, elliptical aperture long axis direction and arc face length limit are in the same way, be provided with rectangle indent in the middle of described trapezoidal faces, be provided with the first mounting hole in the middle of described rectangle indent, two directions, long base, edge of rectangle indent are respectively provided with the second mounting hole; The long base of described trapezoidal faces is removed and is respectively equipped with bending with the long limit of the lap of rectangle indent, arcwall face, the hypotenuse of trapezoidal faces, and described wrap direction is identical with rectangle indent direction, and corresponding to described arcwall face, direction, the center of circle is contrary with wrap direction.

Further, described trapezoidal faces and arcwall face one-body molded, load scope of the present utility model can be increased.

Further, described first mounting hole, the second mounting hole and elliptical aperture are punching.

Further, the center of circle not conllinear of described first mounting hole and two the second mounting holes.

Further, described second mounting hole radius is less than the radius of the first mounting hole.

Further, the hypotenuse of described trapezoidal faces is arc.

Relative to prior art, front lower swing arm large shaft sleeve lower plate described in the utility model has following advantage:

Front lower swing arm large shaft sleeve lower plate described in the utility model can be weldingly connected with front lower swing arm large shaft sleeve upper plate, front lower swing arm large shaft sleeve stabilizer bar arm better, the performance of lower swing arm large shaft sleeve upper plate assembly before improving, prevents from closely not causing distortion because of welding and producing the generation of the situations such as slight crack after using.
