Abstract
The invention relates to a thrusting rod for a suspension of a truck. The thrusting rod comprises two riveted bulbs, a sleeve and two rubber ball joints. The riveted bulbs and the sleeve are assembled by hot riveting, and the rubber ball joint adopts a three-piece outer sleeve radial pre-compressed structure. The flexible material of the ball joints adopts the macromolecule modified rubber material made by using the preparation technology of the in-situ graft modified damping material, which can remarkably improve the stress at definite elongation, strength intensity and tearing strength, etc. of the material, and can obviously lower the use volume of carbon soot of high structure, and improve the cross net structure. As the strength of the chemical action of the interface is high, the fatigue heat build up of the material is lowered obviously, the fatigue damage process and the load performance are improved, and the service life of the rubber bulb joints is prolonged. The rubber bulb joints adopt a three-piece outer sleeve radial pre-compressed structure, which can not only ensure enough radial rigidity for the bulb joints, but also can ensure that the ball joint axles have high press-out force and good deflection and torsion properties.
Description
Technical field
The present invention relates to a kind of automobile component structure, is a kind of heavy-load automobile suspension propelling rod specifically, can be widely used on large-tonnage heavy-load automobile balance suspension or the rubber suspension.
Background technology
Present domestic large-tonnage heavy-load automobile adopts the two back axle steel spring balance suspensions of 6X4 three-axis structure mostly, steel spring plays the trammel beam effect, guarantee in the automobile, each wheel landed when back axle travelled at uneven road surface, in making, the vertical load of back axle wheel distributes comparatively uniformly, but because steel spring can only be transmitted vertical power and side force, can not transmitting tractive power, braking force and the corresponding moment of reaction thereof, these power and moment are mainly transmitted by propelling rod.When on overload of vehicle and non-highway, travelling,, in, the back axle propelling rod often occurs that casing buckling is broken, the fracture of ball pivot mandrel, bulb fracture, polyurethane ball pivot excessive clearance cause quality problems such as noise
Part main engine plants begin trial assembly rubber suspension on the large-tonnage heavy-load automobile now.Rubber suspension is to utilize rubber spring to become the rigidity nonlinear feature, promptly becomes big hard spring characteristic along with amount of deflection increases rigidity, relaxes significantly and impacts, and minimizing is jolted, and improves chaufeur ground labor condition and improves the speed of a motor vehicle; Simplify suspension frame structure simultaneously, alleviate the suspension deadweight; Realization is suspended in zero load and has close natural frequency (2Hz) to the different operating mode of fully loaded, guarantees the stability of vehicle and good ride comfort.The rubber spring of its use mainly bears vertical load, and longitudinal force and moment thereof are mainly by the longitudinal rod transmission.Because this series vehicle is mainly moved on non-highway, the operating mode very severe, the propelling rod that existing technology is produced is difficult to satisfy the requirement of rod member high strength, stability and rubber bushing high performance nature.
Summary of the invention
The objective of the invention is to deficiency at existing large-tonnage heavy-load automobile balance suspension or rubber suspension propelling rod technology and technology, provide a kind of and can guarantee loading strength, can guarantee the large-tonnage heavy-load automobile suspension propelling rod of vehicle stability and good ride comfort again.
The object of the present invention is achieved like this; A kind of heavy-load automobile suspension propelling rod comprises two riveted joint bulbs, a sleeve pipe.It is characterized in that: riveted joint bulb and sleeve pipe adopt hot riveting to be assembled into one, and rivet the pin type rubber bushing that the bulb endoporus are pressed into flexible material two, and rubber bushing adopts the radial precompressed structure of three-clove style overcoat.
Heavy-load automobile suspension propelling rod of the present invention, the macromolecule modified elastomeric material that the flexible material of rubber bushing adopts situ-formed graft modified rubber damping material technology of preparing to make, can significantly improve performances such as material Stress at definite elongation, pulling strengrth, peel strength, and can significantly reduce the consumption of super-normal structure black, improve the structure of cross-linked network, because surface chemistry action intensity height, thereby the heat build-up of material is significantly reduced, the delay fatigue destructive process, the load-carrying properties and the service life of improving rubber bushing.Rubber bushing adopts the radial precompressed structure of three-clove style overcoat, can guarantee that ball pivot radially has enough rigidity, can satisfy ball pivot again and axially have bigger extrusion pressure and deflection torque characteristic preferably, satisfy longitudinal rigidity, the lateral stiffness of suspension, the coupling requirement of roll rate, improved the load-carrying capacity of propelling rod.
Heavy-load automobile suspension propelling rod of the present invention, riveted joint bulb and sleeve pipe adopt the ripple hot riveting to be connected, riveted place ripple is 4～7, has increased the riveted area of contact, bigger raising the rod member torsional property, its rod member antitorque moment can reach more than the 3000N.m.
Heavy-load automobile suspension propelling rod of the present invention, shell material adopts the 20# steel of the Q345C replacement existing product that intensity is high and low-temperature impact resistance is good, the riveted joint bulb adopts modified heat treatment to replace normalizing treatment, the ball pivot mandrel adopts the High Performance 42CrMo material of modifier treatment, bigger raising rod member bear bearing capacity longitudinally, guaranteed the rod member stability in use, significantly improve its fatigue life, propelling rod when having overcome vehicle operating is owing to be subjected to the fracture bending of the sleeve pipe of big pressure generation, quality problems such as bulb mandrel fracture go for large-tonnage heavy-load automobile balance suspension or rubber suspension system.
