Description

Technical Field

[0001] The utility model relates to the technical field of model car suspension, in particular to a model car suspension mechanism. Background Art

[0002] Among various performance indicators of automobiles, automobile aerodynamic characteristics have become an important parameter indicator for consumers to evaluate the quality of automobile styling. Therefore, during the research and development process, we use various modeling processes based on early styling or smoothing data to manufacture 1:1 wind tunnel models for wind tunnel tests. Through wind tunnel tests of models and research on the results, we continuously change styling data and optimize various parameters to provide a theoretical basis for improving the aerodynamic characteristics of mass-produced vehicles.

[0003] The chassis of traditional automobile wind tunnel models is modified from the chassis of batch vehicles, and the front and rear axles and suspensions are batch parts. Therefore, during wind tunnel tests, only chassis and suspensions with similar vehicle heights can be selected, and the selection range is very limited. Secondly, if different vehicle heights need to be simulated, the vehicle height can only be adjusted by placing sandbags on the roof (pits for placing sandbags on the roof are planned in advance) and weighting the model. The vehicle height adjustment range is small, and the test results are limited. In addition, under this process, if tests need to be conducted at different vehicle heights, the vehicle height cannot be adjusted quickly and accurately in the laboratory, and more test time and costs are required. For this reason, we propose a model car suspension mechanism that is convenient for adjusting the vehicle height and easy to operate. Utility Model Content
