Abstract

The invention relates to a rear trailing arm assembly attaching point mounting structure. The mounting structure comprises a attaching point mounting support, a first reinforcing part and a second reinforcing part, wherein the first reinforcing part and the second reinforcing part are connected with the attaching point mounting support; the attaching point mounting support is a sheet metal part which is formed by stamping, is in a "U" shape and is provided with a right side surface, a left side surface and a bottom side surface, wherein a first bolt mounting hole used for being connected witha rear trailing arm is formed in the right side surface, and a right lap joint surface which is bent inwards is connected to the lower side of the right side surface; a second bolt mounting hole usedfor being connected with the rear trailing arm is formed in the left side surface, and a left lap joint surface which is bent inwards is connected to the lower side of the left side surface; a bottomlap joint surface which is bent inwards is connected to the lower side of the bottom side surface; and the first reinforcing part is connected to the left side of the attaching point mounting supportin a positioning mode, and the second reinforcing part is connected to the right side and the bottom side of the attaching point mounting support. According to the rear trailing arm assembly attachingpoint mounting structure, the installation can be carried out at a relatively independent small space position around the periphery, the connection is reliable, the installation structure is simple,the weight is light, and the cost is low.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to a rear trailing arm assembly attachment point installation structure. Background technique [0002] The installation structure of the attachment point of the rear trailing arm assembly is very important to the NVH and handling of the vehicle. In the past models, in order to ensure the performance requirements of the installation structure, a larger cavity structure was often used and reinforcements were used to connect and strengthen the surrounding parts, resulting in an increase in material and process costs and body weight. [0003] Therefore, it is necessary to develop an installation structure in a relatively independent small space around it, so as to reduce the weight and cost of the installation structure while ensuring that the performance of the installation structure reaches the target. [0004] CN204184148U discloses "a connection mechanism of a rear trailing arm assembly", w...
