Description
Technical field
The utility model relates to a kind of knuckle glue core.
Background technique
Joint glue core usually by PU glue as main vibration-absorptive material, as shown in Figure 1, the V bar joint glue core assembly main technique of prior art is that end cap (general employing Q235A stamping straight forming) and axle assembly in joint sleeve are fixed in two ends, be separately fixed in mould and form cavity, utilize polyurethane sulfuration adhesion technique to form shock absorbing resilient body in this cavity and fixing end cap axle assembly in joint sleeve is combined indirectly, in joint sleeve, axle assembly is primarily of axis (forging blank machining) and wear-resisting rigidity joint sleeve (forging blank machining), coordinated by precision machining after heat treatment.
The subject matter of prior art is:
1, glue core shock absorbing resilient body 3 used in conventional joint is all PU glue, although the shock-absorbing capacity of the relatively simple shock absorbing resilient body of the preparation process of PU glue is poor, and particularly higher to the frequency caused from road bump vibrations.The thermal diffusivity of PU glue itself is poor, joint ball pivot can produce heat with joint steel bushing phase mutual friction, the actual life of PU glue material heat modification coefficient considerable influence glue, easily cause come unstuck (ironware and glue bond inefficacy stripping come off), the dead phenomenon such as glue (total failure) and distortion.
2, the axis of joint glue core and rigidity joint sleeve 2 coordinate difficulty of processing excessive.Because axis and rigidity joint sleeve all need higher mechanical property and the processing needing precision higher cooperation just can reach desirable using effect, comprise friction factor each other, abrasion loss, blastic deformation amount etc.Actual need of production probably passes through: in the multiple tracks complicated procedures of forming production processes such as base, roughing, overall modified, fine finishing, cure process, abrasive machining, surface are antirust, quality control is more difficult, and cost is higher.Manufacturing process also relatively backwardness.Axis material adopts workability good 40Cr, and reaches desirable strength requirement by heat treatment, particularly bulb and joint sleeve contact segment be reach required wear-resisting property also will through the operation of the complexity such as Surface hardened layer.
3, very easily there are quality problems in process of production in joint glue core, because the operation various manufacture cycle is also relatively long, needs the manpower and materials of at substantial simultaneously, and cost of production is also relatively high.Because the contractility that the relation of raw material and desirable strength performance guards cost is also less, adds the relatively raw material related to of upper joint glue core components more and comprise iron and steel class and chemical.These parts are worked into surface treatment again to last semi-finished product and finished product from raw material, no matter are all need sizable LOGISTICS COST in our factory or external coordination.
4, rigidity joint sleeve main and ball pivot axis mating spherical surfaces in the middle of the glue core of joint, makes axis rotate within the specific limits.But due to the Spielpassung that both processing needs are certain separately, itself there is certain machining error.Use the rigidity joint sleeve of GCr15 relative poor in antidetonation with shock absorbing performance, in the process that reality uses, ball pivot is main focus, and encourages joint sleeve vibrations to produce certain rigid impact to it.Because joint sleeve toughness is relatively poor, rigidity resilience is not enough.Be easy to cause joint sleeve to crumble, distortion etc.
Model utility content
The utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide a kind of knuckle glue core, and use damping performance is good, impact strength is large.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of knuckle glue core, comprise joint ball pivot, described joint ball pivot comprises a spheroid and is arranged on the convex axle of spheroid relative to both sides, shown spherome surface is injected with nylon inner layer, Stationary Steel Bushing is arranged with outside shown nylon inner layer, shock absorbing resilient body is arranged with outside described Stationary Steel Bushing, the two ends of described shock absorbing resilient body are provided with the fixing end cap for fixing shock absorbing resilient body, and the middle part of described fixing end cap is provided with the through hole allowing convex axle pass.
Further, described nylon inner layer is made up of high-strength abrasion-proof nylon.
Further, described Stationary Steel Bushing is spliced by two semi-circle covers, and use industrial adhesives between described two semi-circlees cover, this industry adhesive bonding fills the gap between Stationary Steel Bushing and spheroid simultaneously.
Further, described shock absorbing resilient body is that compounded rubber makes.
Further, described fixing end cap and Stationary Steel Bushing are Q235 steel work.
Further, described joint ball pivot is that 40Cr steel is done.
Further, the convex axle of described joint ball pivot is provided with penetration hole.
Compared with prior art, the utility model has following beneficial effect:
1, improve the shock resistance of parts, anti-deformation;
2, improve the damping performance of parts, better buffering, shock absorbing and stability are provided;
3, extend the whole service life of parts, after test (environmental simulation), data show that working life of the present invention improves 30%-40% under general vehicle environment;
4, reduce actual production operation, effectively shorten the manufacture cycle, improve the manufacturing efficiency of product;
5, after product normally uses and reaches lifetime limitation, parts can carry out recycling under certain condition.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of original joint ball pivot.
Fig. 2 is the organigram of the utility model embodiment.
In figure: the ball pivot of 1-joint, 2-joint sleeve, 3-shock absorbing resilient body, 4-fixes end cap, 5-nylon inner layer, 6-Stationary Steel Bushing, 7-novel damping elastomer.
Embodiment
Embodiment one: as shown in Figure 2, a kind of knuckle glue core, comprise joint ball pivot 1, described joint ball pivot comprises a spheroid and is arranged on the convex axle of spheroid relative to both sides, shown spherome surface is injected with nylon inner layer 5, Stationary Steel Bushing 6 is arranged with outside shown nylon inner layer 5, novel damping elastomer 7 is arranged with outside described Stationary Steel Bushing 6, the two ends of described novel damping elastomer 7 are provided with the fixing end cap 4 for fixing novel damping elastomer 7, and the middle part of described fixing end cap 4 is provided with the through hole allowing convex axle pass.
In the present embodiment, described nylon inner layer 5 is made up of high-strength abrasion-proof nylon.
In the present embodiment, described Stationary Steel Bushing 6 is spliced by two semi-circle covers, and use industrial adhesives between described two semi-circlees cover, this industry adhesive bonding fills the gap between Stationary Steel Bushing and spheroid simultaneously.
