Counteractive rod assembly of heavy industrial and mining vehicle

Abstract

The invention relates to a counteractive rod assembly specially applied to heavy engineering self-unloading vehicles. The counteractive rod assembly comprises two spherical surface pin assemblies, the spherical surface pin assemblies comprise spherical surface pin metal assemblies and jackets which are vulcanized into a whole by polyurethane elastomers, and the jackets of the spherical surface pin assemblies are pressed into shells in an interference mode. Two shells and a middle connecting rod are combined in a hot-pressing mode to form a complete counteractive rod assembly. According to the counteractive rod assembly, the spherical surface pin assemblies are in a brand-new structure, firstly, an excellent buffer damping curve is provided, torsional moment and deflection torque of spherical surface pins are eliminated, tensile strength and compression resistance of the spherical surface pins are improved, meanwhile, the defect that snap springs are prone to collapse in terms of all existing counteractive rods can be avoided, and the reliability is greatly improved.

Description

technical field [0001] The invention relates to a reaction rod assembly for automobiles, in particular to a reaction rod assembly which is especially suitable for the balanced rear suspension of heavy-duty industrial and mining vehicles. Background technique [0002] As the weight of the truck increases, the structure of the reaction rod is also continuously improved. The focus of the improvement is the spherical pin assembly. The spherical pin assembly is improved from the original sliding bushing structure to an integral vulcanized rubber structure, which improves the life of the components. With the increase of the force on the reaction rod, the rubber structure can not meet the requirements, and the overall vulcanized polyurethane structure spherical pin, its fatigue resistance is much better than that of rubber, due to the large torsional and deflection stiffness of heavy industrial and mining vehicles when driving on poor road conditions , The connecting bolt of the re...

[0002] As the weight of the truck increases, the structure of the reaction rod is also continuously improved. The focus of the improvement is the spherical pin assembly. The spherical pin assembly is improved from the original sliding bushing structure to an integral vulcanized rubber structure, which improves the life of the components. With the increase of the force on the reaction rod, the rubber structure can not meet the requirements, and the overall vulcanized polyurethane structure spherical pin, its fatigue resistance is much better than that of rubber, due to the large torsional and deflection stiffness of heavy industrial and mining vehicles when driving on poor road conditions , the connecting bolt of the reaction rod is easy to fail, and the circlip is easy to collapse. For this reason, we independently designed and developed a spherical pin assembly with a sliding spherical pin inside and an external vulcanized polyurethane structure, which greatly improves the reliability of use.
