Embodiment Construction

[0013] As shown in the figure, in implementation, the airborne equipment 4 needs to be hung on the aircraft body 1 through the pull rod 2, and the airborne equipment 4 is provided with a connecting seat 3 for hanging and a connecting hole on the connecting seat. One end connected to the body 1 is ready for installation, and the other end of the pull rod 2 is provided with a connecting fork 8 for hanging the airborne equipment, and the fork is provided with a connecting hole corresponding to the connecting hole of the equipment connecting seat. During installation, the airborne equipment 4 is placed in a suitable position through the ground support equipment. The shock-absorbing bushing 5 is embedded in the connection hole of the connecting seat 3 of the hanging equipment, and the connecting bolt 6 passes through the central hole of the shock-absorbing bushing 5 and the connecting hole on the connecting fork lug to fix the airborne equipment on the end of the tie rod 2 , the sh...

Abstract

The invention relates to a shock absorption structure of a pull rod suspension device. The shock absorption structure comprises a connection fork lug of a pull rod end, a connection hole which is arranged on the suspension device and a connection bolt, a shock-absorption shaft sleeve is embedded in the connection hole of a suspension device connection seat, the connection bolt runs through a central hole of the shock-absorption shaft sleeve, the shock-absorption shaft sleeve is formed by connecting a left half shaft sleeve and a right half shaft sleeve, which are symmetric to each other, each half shaft sleeve comprises an inner shaft sleeve and an outer shaft sleeve, which are made of two different materials, the abrasion resistance of the inner shaft sleeve is better than that of the outer shaft sleeve, the elasticity of the outer shaft sleeve is better than that of the inner shaft sleeve, the side wall of the outer shaft sleeve is provided with a shock-absorption groove, and the cross section of the inner shaft sleeve is a T-shaped structure.

Description

technical field [0001] The invention relates to the installation technology of the tie rods of aircraft airborne equipment, in particular to a vibration damping structure used for the installation of the tie rods of the airborne equipment. Background technique [0002] Usually, some airborne equipment on the aircraft is installed on the aircraft body in the form of tie rods, for example, refrigeration components of the air-conditioning system. When these airborne devices work, the mechanical vibration generated will have two adverse effects on the aircraft. On the one hand, the mechanical vibration load will be transmitted to the airframe structure of the aircraft through the tie rods, thereby affecting its working performance and service life, and in severe cases, it will lead to early failure of the airframe. On the other hand, the noise generated by mechanical vibration will also be transmitted to the interior of the cockpit of the aircraft through the tie rods, thereby ...
