Example Embodiment

[0042] Example 1

[0043] Figure 1 to Figure 4 This is a schematic structural diagram of a specific embodiment of the present application. The features and advantages of the present invention will be further elaborated below in conjunction with the description of the drawings and specific embodiments.

[0044] The invention relates to a connection structure between a swing arm bushing and a subframe, such as figure 1 As shown, this structure includes a subframe 4 , a swing arm bushing 2 and bolts 3 ; the subframe 4 is connected with the swing arm bushing 2 through the bolts 3 .

[0045] The swing arm bushing 2 and the swing arm sleeve 7 are in an interference fit, and the connection is reliable by relying on this amount of interference. The swing arm bushing 2 is press-fitted with the swing arm sleeve 7, which has certain requirements on the pull-out force of the swing arm bushing. If the pull-out force of the swing arm bushing is insufficient and the vehicle is subjected...

Example Embodiment

[0051] Example 2

[0052] In this embodiment, the structure of the subframe is the same as that of the first embodiment.

[0053] The swing arm bushing in this embodiment includes an inner skeleton, an inner sleeve, a vulcanized rubber body between the inner skeleton and the inner sleeve, an intermediate rubber body, and an outer sleeve tube, which are arranged from the inside to the outside in sequence. In this embodiment, the arrangement of the vulcanized rubber body and the intermediate rubber body can achieve different elastic deformations, which is beneficial to the stability of the swing arm bushing. In this embodiment, the thickness of the vulcanized rubber body and the intermediate rubber body are different, wherein The thickness of the vulcanized rubber body is greater than the thickness of the intermediate rubber body, the thickness of the vulcanized rubber body is 1.1-1.5 times the thickness of the intermediate rubber body, and the elastic coefficient of the vulcani...

Abstract

The invention relates to a structure for connecting a swing arm lining with a sub vehicle frame. The inner framework of the swing arm lining is flat; the two ends of the swing arm lining are protruded out of a middle rubber body and a lining outer pipe; a bolt hole is formed in each of the two ends of the swing arm lining; a through hole is formed in a sub vehicle frame; a threaded casing pipe is arranged in the sub vehicle frame; the bolt holes, the through hole and the threaded casing pipe are communicated with one another; a sink which is toward the inner side is formed in the part, corresponding to each of the middle rubber body and the lining outer pipe, on the sub vehicle frame; the swing arm lining is fixedly connected with the sub vehicle frame in the way that a bolt is matched with the threaded casing pipe. In the technical scheme, due to the fact that the sub vehicle frame is flatly stuck to the inner framework, abnormal sound caused when the inner framework of the swing arm lining moves in the manner of being relative to a gear-starting structure is avoided, and the promotion of NVH (Noise Vibration and Harshness) is benefited; due to the fact that secondary welding of the frame is not required, the rigidity of a mounting part is high, and meanwhile, the mounting space is saved; due to the fact that the sub vehicle frame is molded by drilling and casting a complete plate, the drilling precision is high, and the production is easy to control; due to the fact that the threaded casing pipe is adopted, the assembling process is simple.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a connection structure between a swing arm bush and a sub-frame. Background technique [0002] The subframe can be regarded as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The role of the subframe is to block vibration and noise, reducing its direct entry into the compartment. This suspension assembly with subframe, in addition to bringing various conveniences and advantages in design and installation, the most important thing is the improvement of its comfort and suspension rigidity. Some spare parts of the suspension are assembled to the subframe to form an assembly part and then connected to the body, which brings convenience to the assembly. The subframe is generally connected to the body through rubber bushings. [0003] The introduction of rubber components into the suspension system can ...
