Description
Technical field
The present invention relates to automobile suspension system, particularly relate to a kind of support rod mechanism, irs control arm and automobile in automobile suspension system.
Background technology
Control arm in automobile suspension system is generally A arc or the split-type structural that is fixedly connected with strut bar by swing arm forms.Strut bar in this split-type structural and vehicle body adopt pin type lining elasticity to be connected, and form support rod mechanism, and this support rod mechanism has the effect supporting and cushion forward and backward longitudinal force.
The structure of the support rod mechanism of current employing as shown in Figures 1 to 5, comprise strut bar 1, support 2, lining 3, front disc 101, rear disc 102 and jam nut 4, support 2 comprises front plate 201, rear plate 202 and stay bearing plate 203, as shown in Figure 3 to Figure 4, confined state when lining 3 is in non-pretension as shown in Figure 5 for structure when lining 3 is in free state.
In the course of the work, there is following problem in this structure:
1) as shown in Figures 3 to 5, when non-pretension, the lining 3 being positioned at front end only has bottom face 304, convex part 303 is fitted with front plate 201 respectively, and the lining 3 being positioned at rear end only has bottom face 304, convex part 303 is fitted with rear plate 202 respectively, gap is had between the curved transition sections 302 of lining 3 and the installation groove surface 2022 of front and back clamping plate 202, gap is had between the curved transition sections 302 of lining 3 and rear front plate 201, in pretension process, there is the precedence of fitting in lining 3 and rear plate 202: convex part 303 is to installing groove surface 2023, bottom face 304 is to installation groove surface 2021, curved transition sections 302 cannot be fitted with installation groove surface 2022 and be formed gap.Meanwhile, lining 3 and front plate 201 are also fitted in symmetric position, and between lining curved transition sections with front plate 201, same cannot laminating forms gap.After pretension, this gap still exists, and the bottom face 304 of lining 3, stress amplitude ratio curved transition sections 302 place at convex part 303 place are much bigger;
2) when strut bar 1 bears larger longitudinal force and swings up and down time, the lining 3 being positioned at front end steps up further, the lining 3 being positioned at rear end relaxes, in the side of lining 3 being positioned at rear end, lining 3 disengages with the groove of rear plate 202, when longitudinal force diminishes and swing very little, the lining 3 being positioned at rear end recovers again the fit-state described by above-mentioned 1st;
3) as described in above-mentioned 2nd, owing to constantly repeating to fit, depart between the lining 3 and rear plate 202 of rear end, the lining 3 being positioned at rear end is very large with rear plate 202, strut bar 1 Relative sliding, easily causes the wearing and tearing at lining 3 301 positions bottom bottom face 304, convex part 303 and endoporus being positioned at rear end.
4) as described in above-mentioned 3rd, because Relative sliding is very large, the phenomenon such as noise, abnormal sound is easily caused;
5) because situation about disengaging appears in the lining 3 that is positioned at rear end and rear plate 202, the lateral rigidity of lining 3 reduces, cause strut bar 1 touch front plate 201, rear plate 202 endoporus and produce beat noise.
