Abstract
The utility model aims to provide an upper swing arm mounting support on a rear auxiliary frame. The strength and the rigidity of the support are improved. In order to achieve the purposes, the upper swing arm mounting support on the rear auxiliary frame comprises a front face, side faces and a rear face, wherein the front face, the side faces and the rear face are integrally formed in a stamping mode, the support is provided with a cutting edge, and the cutting edge can be connected with a rear auxiliary frame longitudinal beam in a welding mode. The support is characterized in that the middle fracture surface of the front face is in the shape of W, the middle fracture surface of the rear face is in the shape of W, and a free edge cutting area of the support is a non-welding side area and in the shape of W.
Description
Technical field
The utility model relates to Rear secondary frame for vehicle top link mounting bracket.
Background technology
Rear secondary frame for vehicle top link mounting bracket is the top link mounting bracket of Rear secondary frame for vehicle in a kind of rear multi-link bar independent suspension, its function is to provide installing and using of top link, formation is controlled the performance perameter of vehicle camber angle and roll center, plays the function of transmission power and guiding simultaneously.
As shown in Figure 2, this support 1 by above 11, side 13,12 form below, before 11,12 have respectively mounting hole 10 below, being shaped as in the circle of the section by A-A line from Fig. 4, Fig. 5 is Z-shaped, this support 1 and the welding process that longeron assembly carries out, adopt traditional turnup structure technique for controlling its weight.In design, be difficult to meet X-direction, the requirement of Y-direction strength and stiffness of support 1.
Utility model content
The purpose of this utility model is to provide a kind of Rear secondary frame for vehicle top link mounting bracket, and intensity, the rigidity of this support are improved.
For realizing the Rear secondary frame for vehicle top link mounting bracket of described object, before comprising that integrated punching is shaped, side and below, this support has trimming, its can with Rear secondary frame for vehicle longitudinal beam welding, be characterized in, middle discontinuity surface is above W shape, after in discontinuity surface be W shape, and the free scrap region of this support is that non-welding edge region is W shape.
Described Rear secondary frame for vehicle top link mounting bracket, wherein, described side has lightening hole.
By Z-shaped, be changed to W shape, it contributes to improve strength and stiffness.

The specific embodiment
As shown in Fig. 1, Fig. 6 to Fig. 9, Rear secondary frame for vehicle top link mounting bracket 2 is drawing part, comprises above 21, side 22 and 23 below, also has trimming 24, by trimming 24 and longeron 3, is overlapped and is welded.
From by the section of B-B line, its mounting hole 20 is (middle discontinuity surface above, below) to the region between the centre of trimming 24, in Fig. 8, in position a, Fig. 9, shown in the b of position, is shaped as W shape, and 21, below 23 middle discontinuity surface is W shape above.
From the section of B-B line, its mounting hole 20 to free trimming is the region (free scrap region is non-welded lap edge regions) between non-welding scrap (bridge) again, i.e. position d in Fig. 8 is shaped as W shape in Fig. 9 shown in the c of position.
In addition, also have lightening hole 220 on side 22, the size of lightening hole 220 can suitably be adjusted, and method of adjustment can be to calculate rear adjustment by computer aided analysis software (CAE).
By comparison diagram 2, to Fig. 5, Fig. 6 to Fig. 9, the section form that can find to improve front corresponding region is Z-shaped, and after improving, the section form of corresponding region is W shape.
Aforementioned Z-shaped, W shape is not completely identical with zed, W shape, but its section extension and zed, W are the same, has turning back of same number.
In contriver's test, according to the Rear secondary frame for vehicle top link mounting bracket of previous embodiment, do not changing on basis material wall thickness and materials weight, effectively improved this support the quiet rigidity of X-direction, Y-direction, (X-direction improves more than 25%, Y-direction improves more than 5%), the Joint strenght distribution of stress of support and trailing arm has reduced by 25%.
Accurate handling directive property and good reliable in structure life-span are played in exploitation for the promotion performance type car of rear multi-connecting-rod separated suspension after this structure applications.
