The invention belongs to the damper reliability test technology field and relates to an electric vehicle hydraulic damper reliability test device capable of simulating actual condition loading. A problem that an existing reliability test device can not carry out a reliability test on an electric vehicle hydraulic damper is solved. The device comprises a vertical loading portion, a horizontal loading portion, a counterweight loading portion, a hydraulic portion and a temperature and humidity loading portion. The axis of the vertical hydraulic cylinder of the vertical loading portion, the axis of a number 1 pull pressure sensor, the axis of a vertical force application rod and the symmetrical center wire of a vertical support frame are collinear and are vertical to the upper surface of horizontal iron. The axis of the horizontal hydraulic cylinder of the horizontal loading portion, the axis of a number 2 pull pressure sensor and the axis of a linear optical axis are collinear and are parallel to the upper surface of the horizontal iron. A front-fork symmetrical center line, the axis of a force bearing rod and the symmetrical center line of a counterweight bench are collinear.
Description
technical field [0001] The invention belongs to the technical field of shock absorber reliability tests, and in particular relates to a reliability test device for electric vehicle hydraulic shock absorbers capable of simulating loading under actual working conditions. Background technique [0002] With the rapid development of electric vehicles in China, electric vehicle hydraulic shock absorbers are widely used. Electric vehicle hydraulic shock absorber is one of the important key components of electric vehicles, and its quality directly affects the comfort and safety of electric vehicles. Experts and scholars have conducted a lot of research on model establishment, theoretical analysis, dynamic analysis, structural analysis, etc., and have achieved important research results. However, the reliability test device for the key components of the electric vehicle hydraulic shock absorber is extremely rare in China, and usually only conducts the reliability test on the site of...
