Frequency-regulation amplitude-variable automobile suspension characteristic detection table

Abstract

This invention discloses a property test desk for FM variable amplitude car hangers, which fixes two same sets of exciting desks with FM and variable amplitude function at either end of a straight frame oppositely and the axes of two rotation mandrels contained in the exciting desks share one, the function is realized by the frequency adjust device and the amplitude regulation device, the car protection device is fixed on the base located above two vibration rest frames in the vibration maintenance and a guiding unit and below the vibration board, which realizes the active vibration of right and left exciting desks.

Description

technical field [0001] The invention relates to a detection device for automobile performance, in particular to a detection platform for suspension characteristics of small automobiles. Background technique [0002] At present, domestic and foreign automobile suspension characteristic test benches generally adopt resonant test benches. According to the different detection parameters, the resonant testing platform can be divided into two types: force-measuring and amplitude-measuring testing platforms. Among them, the force-measuring test bench is widely used. [0003] The automobile suspension characteristic dynamometer test bench uses the principle of detecting the wheel and road grounding force to quickly evaluate the quality and performance of the automobile suspension, and uses the measurement standards recommended by the European Shock Absorber Manufacturers Association (EUSAMA). The steady-state load on a car wheel is defined as the static ground force between the wh...

AI Technical Summary

Problems solved by technology

[0006] 1. Existing vehicle suspension characteristic test benches can only sweep the left and right wheels from high frequency to low frequency. The vibration frequency cannot be controlled, and the sweep time cannot be controlled.

[0007] 2. The eccentric distance of the eccentric mechanism of the existing automobile suspension characteristic testing platform cannot be adjusted, so the amplitude of the vibrating plate of the testing platform is fixed, and it cannot simulate the actual road conditions for real-time input

[0008] 3. The detection parameters are single, and the in-depth performance analysis and fault diagnosis of the automobile suspension cannot be carried out, and the technical status of the automobile suspension cannot be fully reflected. The detection results are not conducive to guiding the maintenance work of the automobile repair shop

[0009] 4. The axle load of vehicles allowed to pass through one side of the existing vehicle suspension characteristic testing platform is 2t, so vehicles with excessive axle loads will not be able to pass through the testing platform
