Abstract
The utility model relates to an automobile air suspension device with a pyrocondensation welding thrust bar, comprising a bar body made of steel in round tube shape, an annular cast steel end of unequal thickness and a rubber hinged joint assembly. The utility model is characterized in that after pyrocondensation the bar body and a solid circle handle of the end form an assorted segment, and an annular welding line and the end are connected at the place of a weld groove of the bar body. The utility model has the advantages of good technological and economic property as well as enhanced safety and reliability in automobile operating.
Description
Technical field
The utility model relates to a kind of pyrocondensation and adds welded type propelling rod automobile air suspension gear.
Background technology
Pyrocondensation adds welded type propelling rod automobile air suspension gear, does not see relevant report at home and abroad.Report has hot extrude pressure type propelling rod or pure welded type automotive track bar etc. at present.They mainly are made up of following parts: the body of rod, termination, rubber hinge head, mandrel, lining.The body of rod of hot extrude pressure type propelling rod is being to push the wave structure that forms with the termination section of joining; Pure welded type automotive track bar has the weld metal zone at the body of rod and joint, termination.They exist following problem and shortcoming:
1) hot extrude pressure type automotive track bar producting process difficulty is big, is difficult for grasping, and easily causes quality fluctuation.This is the corrugated that will be hot extruded into certain size because of the body of rod and the section of cooperation of termination, and also will there be the suitable magnitude of interference steel pipe pole endoporus processing back when cooperating with the termination.Steel tube inner hole machine up is very difficult, and the otch that processing causes easily produces stress concentration, influences intensity.In addition, in hot extrusion process,, reduce stability, influence the product in-use performance because of the tool locating difficulty easily makes the distortion of body of rod generation permanent bend.
2) the hot extrude pressure type automotive track bar plant-scale equipment is many, as induction heater, compression machine, hot-extrusion mold, hot extrusion fixture clamping fixture etc., cost height.
3) though pure welded type automotive track bar production technology is simple, body of rod steel pipe and termination free-running fit, stability and Joint strenght are poor, are prone to fracture.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of existing favorable manufacturability and economy to be provided, and can strengthen the safety in the car running process and the pyrocondensation of reliability again and add welded type propelling rod automobile air suspension gear.
The purpose of this utility model realizes in the following manner:
The utility model comprises the steel tubular body of rod, uniform thickness ring-type cast steel termination, rubber do not cut with scissors head assembly, and it is characterized in that: the body of rod forms the section of cooperation with termination filled circles handle after pyrocondensation; The place is connected by circumferential weld and termination at body of rod groove.
The utility model has the advantages that:
1) the propelling rod body of rod adopts pyrocondensation to add the method for welding with the section of cooperation of termination, makes technological operation easy, and reliable product quality is applicable to production in enormous quantities.
2) the cooperation section after the pyrocondensation can be born very big push-pull effort, and the interference fit section of certain-length has improved the anti-unstability ability of rod member greatly, has avoided free-running fit easily to cause commissure stress raisers, the impaired disadvantage of rod member again; Add circumferential weld and connect, further improved the stiffness of propelling rod, as the same double insurance.
3) the required production facilities of the utility model is few, because the interference fit between the tubulose body of rod and termination cylinder handle only adopts the natural shrinkage mode in heating back, thereby saved hundreds of tons of oil presses, thereby makes moulds of industrial equipment simpler, machine up is simple.The steel casting termination is lower than forging expense under the same performance condition in addition, good welding performance, thereby can reduce the production experimental manufacturing cost greatly.
4) use the utility model can improve the automobile hanging performance, improve the reliability and stability of vehicle operating.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of propelling rod welding assembly; Fig. 3 be the tubular body of rod structural representation; Fig. 4 is the structural representation of rubber hinge head assembly and propelling rod termination.
The specific embodiment
With reference to accompanying drawing, the utility model comprises the steel tubular body of rod 2, termination 1, rubber hinge head assembly 3 (comprising rubber hinge head, lining, mandrel), and two same terminations 1 are contained in the two ends of the body of rod 2 respectively, and termination 1 is the annular steel casting of equal thickness not.The interior external diameter of the tubular body of rod 2 does not carry out machine up, it forms interference fit with the cylinder handle of the appropriate length of termination 1 after pyrocondensation, and, form tangible circumferential weld 4 at the groove place of pipe and termination root annular weld together, constituted the welding assembly of propelling rod; Rubber hinge head, steel sleeve, steel core axial compression are contained within the termination 1.
After the utility model pyrocondensation adds welded type propelling rod automobile air suspension gear design and trial-produces successfully, successively carried out the distance rod assembly load carrying capacity test, hinge maximum load capacity test and overload test, a rubber hinge fatigue test all is higher than the engineering factor requirement of regulation.The distance rod assembly of new trial-production has been loaded onto Qingdao car, north benz truck, the Shaanxi car that steams that steams and has been accepted examination, and wherein benz car in the north has been finished 14000 kilometers preventing tests on the various complex road surfaces, does not take place any unusual, functional.
Claims (2)
1. a pyrocondensation adds welded type propelling rod automobile air suspension gear, comprises the steel tubular body of rod, uniform thickness ring-type cast steel termination, rubber hinge head assembly, and it is characterized in that: the body of rod forms the section of cooperation with termination filled circles handle after pyrocondensation.
2. pyrocondensation according to claim 1 adds welded type propelling rod automobile air suspension gear, and it is characterized in that: the place is connected by circumferential weld and termination at body of rod groove.
