AI Technical Summary

Problems solved by technology

The rubber parts are impacted by the sphere, the plastic sleeve, and the connecting hole of the end cap in one direction, and are easily torn and broken during the multi-directional deformation and fatigue process.
After these rubber and plastic joint assemblies are installed on both ends of the reaction rod body and connected to the car, the service life of the reaction rod assembly is short due to the heavy load of the car and the poor road conditions, and the reaction rod joint assembly is prone to damage
In addition, the rubber joint assembly with rubber joint assembly such as the reaction rod is subjected to relatively large force and deformation. Since each end of the original rubber joint is connected by a single bolt, relative rotation between the bolt and the end is easy to occur, so the phenomenon of bolt loosening is relatively serious. , resulting in damage to the rubber joint assembly, causing the rubber joint assembly with the reaction rod to fail more easily, which cannot meet the long-term service life and performance requirements of the car

Abstract

The invention provides a counteractive rod assembly with a rotary type joint and a wear-resistant bushing. The counteractive rod assembly and a metal joint connecting hole in an end part are internally provided with a wear-resistant bushing, an engineering plastics joint assembly, an end cover and a dustproof loop respectively, a rubber-plastic joint assembly is a spherical pin shaft and engineering plastics ball bases covered outside the spherical part in the middle of the spherical pin shaft, the engineering plastics ball bases are two ring-shaped petal engineering plastics ball bases which are bilaterally and symmetrically butted with each other along the axial direction, the joint connecting hole in the end part of the counteractive connecting rod is further internally provided with a ring groove, the ring groove is internally provided with a plastics wear-resistant bushing, the wear-resistant bushing is in interference fit with the ring groove, and a cylindrical surface outside each engineering plastics ball base is in interference fit with the wear-resistant bushing. The wear-resistant bushing part is taken as an elastic deformation buffer part and is applied by the extrusion force and the impact of a ball body and the ball bases and the friction force caused by the rotation of the ball body and the ball bases. The teflon or hard polyurethane wear-resistant bushing which is sealed in the ring groove in the connecting hole has the characteristics of being high in strength, good in wear resistance, good in oil resistance and the like, so that the pressure for buffering the ball base can be kept.
