Description
Technical field
The present invention relates to a kind of automobile distance rod assembly, especially a kind of V-type distance rod assembly that is applicable to heavy duty truck balance rear-pendant.
Background technology
The last lower thrust rod of conventional heavy-duty lorry balance rear-pendant is straight-bar, and leaf spring bears transverse force, and along with the wearing and tearing of parts, automobile located lateral function worse and worse; Advanced now balance rear-pendant generally assembles individually balanced axle assembly in the left and right sides and V-type propelling rod, thereby automobile located lateral function is optimized greatly, and suspension property is greatly improved.
The V-type distance rod assembly generally is divided into three rubber ball-and-spigots and end rubber sphere pin, two kinds of versions of middle ball-and-socket hinge style.Two kinds of structures are all generally used now, select for use a kind of structure in back more under heavily loaded situation, and its profile as shown in Figure 1.
The V bar shortcoming of three rubber sphere latch structures be whole sulfuration the rubber sphere pin reversed, under the external force combined actions such as deflection and extruding, the rubber of ball pin comes unstuck easily, tears, the intermediate pin is because stressed bigger, failure frequency is just higher;
The distance rod assembly of heavy wrecker truck balance rear-pendant is the important stressed member of suspension system, and its higher damage rate is the problem of car load and component manufacturer headache always, and the main position of damage is at ball pin assembly.Traditional ball pin assembly of end rubber sphere pin, middle part spherical hinge structure V bar adopts the polyurethane slide construction, the ball pin of this structure is very short in heavy duty and following life-span of impact load, reliability is relatively poor, usually adopt the ball pin assembly of whole sulfuration structure now, the service life of this ball pin is longer than conventional confguration, but the rubber sphere pin of whole sulfuration reversed, under the external force combined actions such as deflection and extruding, the rubber of ball pin comes unstuck easily, tears and extrudes, finally cause ball pin failure, influence vehicle performance, so also there is certain limitation in this structure.
The middle ball pivot assembly of end rubber sphere pin, middle part spherical hinge structure V bar comprises in-to-in spheroid and exterior non-metal ball cover, ball cover is made up of the higher non-metal High molecular material of hardness, though it is wear-resisting but quality is more crisp, when ball pivot overcoat when withstanding shocks load cracked easily, cracked back ball pivot lost efficacy, influence vehicle performance, so also there is certain limitation in this structure.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, tension pressure energy power is strong, tear resistance is high, strong shock resistance, the V-type distance rod assembly that is applicable to heavy duty truck balance rear-pendant that reliability is high.
The objective of the invention is to adopt following technical proposals to realize: a kind of V-type distance rod assembly that is applicable to heavy duty truck balance rear-pendant, comprise the end ball pin assembly and the middle part ball pivot assembly that are connected, the end ball pin assembly comprises that the ball gold-sprinkled belongs to oscillating bearing and end cap, described ball gold-sprinkled belongs to oscillating bearing and comprises ball pin and friction pair outer ring, the middle part of ball pin is spherical in shape, the ball pin outside is equipped with the friction pair outer ring that cooperates with it, the two forms the friction pair of a universal movement form, the outer circumference surface sulfuration of friction pair outer ring has one deck polyurethane, and polyurethane is one with friction pair outer ring and two end cap sulfurations.
The spherical surface of ball pin is provided with and is staggered form distribution oil resevoir A.
Described friction pair outer ring is split type or one-piece construction, and outside, split type friction pair outer ring is fixed into one by the spring retainer.
Described middle part ball pivot comprises spheroid, and the spheroid outside is provided with metal bearing with matching outer ring, and the metal bearing outer ring is installed in the upper ball base, is provided with securing device between top, metal bearing outer ring and upper ball base.
Radially be provided with taper hole on the described spheroid.
The outside face of described metal bearing outer ring is cylindrical, and the metal bearing outer ring is provided with oil resevoir B.
Described metal bearing outer ring is split type or one-piece construction, and integral type metal bearing outer ring is provided with fitting recess.
Described securing device is jump ring A or bolt or plug.
Sphere is processed at ball pin middle part, end of the present invention, the metal outer ring that outside assembling cooperates with it, and the friction pair that the two forms a universal movement form when propelling rod reverses with yaw motion, all can be converted into the slide relative of this friction pair; Metal outer ring outer circumference surface vulcanizes one deck polyurethane again, and when the ball pin carried out above-mentioned motion and withstands shocks, polyurethane elastomer only bore extruding, because stressed simplification and only bear the pressure that elastic body is good at tolerating, so the ball pin assembly life-span improves greatly.Lubricated and traditional ball pin of this ball pin assembly is basic identical, and ball pin assembly method and rubber sphere pin assembly are basic identical.
End ball pin adopts friction pair to add the sulfuration polyurethane structural, not only given full play to the polyurethane elastomer high resiliency, highly anti-fatigue, anti-extrusion advantage, thereby guaranteed the original cushion characteristic of V bar, avoided simultaneously the rubber sphere pin in the stressed shortcoming that lost efficacy easily when excessive again, improved the reliability of V boom end ball pin greatly, universal friction pair structure makes that V boom end ball pin moment of torsion when reversing with deflection is minimum, shearing force and partial high pressure that former rubber bears have been cut down greatly under above-mentioned operating mode, above-mentioned two kinds stressed be the major cause that V bar rubber sphere pin damages, ball pin assembly has also reduced the moment of flexure of V bar binding bolt when reversing and reducing with the deflection moment of torsion, make and bolt strainedly improve greatly that this will greatly improve the life-span of V bar bolt; The outer ring of ball pivot assembly changes into behind the metal joint outside race by non-metal and spheroid is formed the friction pair of a precision in the middle of the V bar, because tolerance clearance is very little, so friction pair can not produce impact, Internal and external cycle is heat-treated simultaneously, so good wear ability is arranged, this has also greatly improved the ball pivot assembly in heavy duty and the reliability and the service life of impacting under the operating mode.The present invention has eliminated ball pin twist moment and deflecting torque by thoroughly changing end rubber sphere latch structure and changing elastomeric material, has improved the tension pressure energy power of ball pin simultaneously; Middle ball pivot assembly outer ring lagging material is changed into the metal bearing outer ring by non-metal and inner ring adopts the only motion play of 0.06-0.12 millimeter, improved the impact resistance of ball pivot when guaranteeing resistance to abrasion, thereby improved V bar reliability.
