The invention provides a Macpherson suspension shock absorber lateral force measuring method and a Macpherson suspension shock absorber lateral force auxiliary measuring tool. A shock absorber penetrates a guiding seat on a vehicle body and is connected with a vehicle body tower bag. The above method includes the steps that firstly, the X-direction position and the Y-direction position of a piston rod of the shock absorber of the vehicle body is marked on the vehicle body; secondly, the shock absorber of a vehicle and an installation base are demounted, and a test shock absorber is installed on the vehicle body through a test installation base; thirdly, a piston rod of the test shock absorber is wobbled till the X-direction position coincides with the Y-direction position, and the lateral force at the end portion of the piston rod of the test shock absorber is detected; and fourthly, the lateral force at the position of the piston rod of the test shock absorber and the lateral force at the position of the guiding seat are calculated according to the lateral force at the end portion and the lever ratio. By means of the method, the supporting force at the position of the piston rod of the shock absorber of the vehicle and the supporting force at the position of the guiding seat can be actually measured, and compared with the prior art, the measurement value is more accurate, and the quality of a Macpherson suspension can be better ensured.
Description
technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to a method for measuring the lateral force of a MacPherson suspension shock absorber and an auxiliary measuring tool thereof. Background technique [0002] MacPherson suspension has the advantages of compact structure, small space occupation, small stress on the connection point between the shock absorber and the body, and the hinge point between the lower arm and the subframe, and low cost. At present, most of the front suspensions of passenger cars are MacPherson independent suspension is adopted, and the rear suspension of some models also adopts MacPherson independent suspension. In the MacPherson suspension structure, the shock absorber is an important guiding structure and load-bearing structure. There is a large lateral force between the piston rod of the shock absorber and the guide seat at the upper end of the shock absorber, so that the piston rod and t...
