Abstract
The utility model relates to a steering knuckle, which comprises a steering knuckle body, the upper end of the steering knuckle body is provided with a connecting platform I and a connecting platform II which are centrosymmetrical, and each platform is provided with two threaded holes for connecting and fixing a front shock absorber assembly. The connecting platform I and the connecting platform II are connected together through a semicircular connecting ring to form the shape of an Omega. The inner side of the semicircular connecting ring is provided with three crisscross reinforcing ribs. The steering knuckle has the advantages that the steering knuckle is easy to shape by casting, has high bearing capability and reliability, is convenient to mount and dismount for the installation of the shock absorber assembly, and can be well and reliably positioned.
Description
Technical field
The utility model relates to automotive suspension and steering swivel system, especially a kind of steering swivel.
Background technology
Preceding steering swivel belongs to automobile front suspension and steering swivel system parts, mainly is the anterior load of bearing automobile, and supporting also drives front-wheel steering.
In car load was arranged, steering swivel upper end damping arm was installed with the front shock absorber assembly and is connected.When automobile travelled on rough road surface or be subjected to the significant load impact, bump rubber, spring etc. produced very big axial force, act on the bumper, and huge test is born in steering swivel damping arm position.
Now using in the structure, the steering swivel upper end is provided with the damping arm, is used to connect vibration damper assembly.Utilize two groups of bolts, nuts to be fastenedly connected by hanger and the steering swivel damping arm that is welded on the bumper urceolus between steering swivel and the vibration damper assembly.That is, two groups of bolts pass shock absorber shackle and steering swivel damping arm hole, and both are fixed.Matching requirements height, and difficulty not only need be aimed at knuckle bores, and are difficult to assembling when the hole of hanger both sides right alignment is overproof; Steering swivel damping arm dimension overproof can cause can't pack into hanger or excessive clearance; Tie bolt and knuckle bores and hanger hole are gapped, influence vibration damper assembly attitude is installed, and the location is difficult; The binding bolt that is adopted is longer, to having relatively high expectations of bolt.
Now use the steering swivel damping arm position in the structure relatively weak, and far away from center of gyration, the arm of force is bigger, and steering swivel damping arm place is subjected to moment bigger, and damping arm place easily produces distortion, even fracture.Now using in the structure, because reasons in structure, steering swivel damping arm is in and very easily occurs shrinkage porosite and sand holes defective in the casting process, directly influences the working strength of steering swivel.From the another one angle, vibration damper assembly produces very big axial force when work, and directly act on two groups of bolts, the nut, the requirement of its intensity axial force that often out of reach bore, in case and connecting portion lost efficacy, vibration damper assembly can lose support and collapse, and consequence is hardly imaginable.So, be the task of top priority to improvement now with slewing journal structure.
In Chinese patent ZL200820168722.8, a kind of slewing journal structure is disclosed.In process of production, we find, though the improvement slewing journal structure has some advantages existing aspect load-carrying capacity and the reliability with structure, the circular hole of steering swivel upper end in splitting the groove course of processing, serious mistake circle phenomenon can occur.After splitting groove, steering swivel upper end circular diameter, it is big that the appearance size that has becomes, the appearance size decreases phenomenon that has.It is big that size becomes, and can cause the tie bolt lock tight or adorn not in place; Size decreases directly causes vibration damper assembly to assemble.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of easy casting is provided, and load-carrying capacity and reliability are stronger, and is beneficial to the steering swivel of vibration damper assembly dismounting and location.
The utility model solves the technical scheme that its technical matters adopts: a kind of steering swivel, comprise the steering swivel main body, steering swivel main body upper end is provided with two centrosymmetric connection platform I and is connected platform II, respectively is provided with two tapped bore that are used to be connected and fixed the front shock absorber assembly on each platform.
As preferably, integral body is " Ω " shape to described connection platform I with being connected that platform II connects by semicircle coupling link.
As preferably, described semicircle coupling link inboard is provided with three crisscross reinforced ribs.
The effect that utility model is useful is: one, two the connection platforms in steering swivel upper end connect by semicircle coupling link, and " Ω " shape has the easy advantage of casting, and are difficult for producing shrinkage porosite, sand holes defective; Two, steering swivel connects platforms by two and fixes vibration damper assembly, has assembling and convenient disassembly and Joint strenght height, advantage that bearing capacity is strong; Three, in the coupling link of steering swivel upper end three crisscross reinforced ribs are arranged, can further improve intensity, reliability and the load-carrying capacity of steering swivel; Four, steering swivel upper end flat surface is set rational planeness requirement, and the control accuracy of thread, can guarantee the installation attitude of vibration damper assembly on car load, have the advantage of having good positioning.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Description of reference numerals: connect platform I1, connect platform II2, semicircle coupling link 3, reinforced rib 4, tapped bore 5, steering swivel main body 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: as Fig. 1, a kind of steering swivel comprises steering swivel main body 6, and steering swivel main body 6 upper ends are provided with two centrosymmetric connection platform I1 and are connected platform II2, respectively are provided with two tapped bore 5 on each platform, is used for connecting, fixing front shock absorber assembly.Connect platform I1 and be connected platform II2, be " Ω " shape, have the simple advantage of casting by semicircle coupling link 3 connections.Semicircle coupling link 3 inboards are provided with three crisscross reinforced ribs 4, can guarantee steering swivel intensity, reliability and load-carrying capacity.Simultaneously, steering swivel upper end platform is set rational planeness requirement, and control the precision that is threaded, can guarantee the installation attitude of vibration damper assembly on car load, have the advantage of having good positioning.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
