Abstract

The invention relates to an experimental device for pulling off the ball end of a tailgate electric strut, comprising a hydraulic machine base, a tooling base is arranged on the working table of the hydraulic machine base, and the feature is that a lifting transmission device is installed above the tooling base, and the lifting transmission device The lifting drive end is connected to one end of the tension sensor, and the other end of the tension sensor is connected to the ball core rod, which is used to cooperate with the ball socket in the ball head; the ball head is threadedly connected to one end of the connecting rod, and the connecting rod Secure with fixings. The invention can effectively measure and calculate the pull-off force of the ball head and ensure the stability of the connection of the struts.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for pulling off a ball end of an electric support rod of a tailgate. Background technique [0002] With the development of the economy, people's living standards are constantly improving, and the demand for cars is increasing. The strut is a necessary auxiliary structure for opening the tailgate of the car. There are two kinds of existing car struts, one is pneumatic spring, which uses compressed air to generate the principle of air pressure difference to assist the opening of the tailgate; the other is electric strut, which uses electrical energy to convert into mechanical energy to completely release the hands. Both of the above two auxiliary structures can complete the opening and closing of the auxiliary tailgate, and the two auxiliary structures need to be connected to the vehicle body and the tailgate through component ball joints respectively. There are two...
