Abstract
The utility model relates to a supporting axle end structure, which can be applied to both ends of a driving axle of a loader and can be applied to both ends of a driving axle of an engineering machine, and can support and absorb braking torque. The structure of the utility model is that an axle sleeve is an integral component with a brake caliper plate; the axle sleeve and a sleeve, and the axle sleeve and the driving axle respectively form matching interference connection with each other by using temperature difference method through a cylindrical surface. The utility model maximumly reduces defects caused by weld, ensures the flatness of the friction surface of the brake caliper plate and the verticality of the friction surface of the brake caliper plate relative to a mounting reference surface, and can effectively increase positioning accuracy, stability and bonding strength.
Description
The utility model relates to loader and engineering mechanical components technical field, especially a kind of supporting axle end structure that is applied in ransaxle two ends, a supporting of loader and engineering machinery and absorbs braking moment.
The ransaxle two ends of engineering machinery such as present loader, its axle head structure adopts mutually independently caliper plate and supporting axle respectively, and these two parts are welded on the two ends of ransaxle subjective basis Cast Steel respectively.Supporting axle is selected integral quenching with forging blank usually, because the final forging temperature of forging control difficulty, and the exterior cross-section size great disparity of circular supporting axle is bigger, thereby easily causes the microscopic crack defective of forging, and integral quenching has increased the weight of the crackle tendency; Moreover, this supporting axle is welded on the ransaxle main component, because be the bigger materials welding of two kinds of difference, can make that the embrittlement tendency of weld seam material around tissue becomes greatly on the quenching part, fracture is arranged during these parts in the use; The 3rd, when the welding caliper plate, be the method that adopts second positioning, clamping, its welding back positional accuracy is low and nipper is bigger because of the particularity distortion of its structure shape, directly influences braking effect.
Deficiency at above-mentioned prior art exists the utility model proposes a kind of integrated supporting axle head, and its connection is reliable, and coaxality is higher, has strengthened the intensity and the rigidity of assembly parts, can effectively ensure braking ability.
The purpose of this utility model realizes by following measure: the structure characteristic of supporting axle head is: the axle sleeve frenulum has the one-piece parts of caliper plate, on the inner headed face of this axle sleeve coaxial be provided with one sufficiently long in order to stable, the cylndrical surface of grip sleeve and the short cylindrical locating face that cooperates with ransaxle, between axle sleeve and the sleeve pipe by cylindrical interference cooperation connection.
An end that connects with axle sleeve on the described sleeve pipe has the convex shoulder structure of preventing deviating from.
Following structure embodiment and accompanying drawing thereof elaborate to the utility model.
Fig. 1 is an axle sectional structure schematic representation of the present utility model.
Fig. 2 is the sectional drawing of Fig. 1 Intermediate shaft sleeve.
Fig. 3 is the sectional drawing of Fig. 1 middle sleeve.
As shown in the figure, structure of the present utility model is to be coupled to an integral body by axle sleeve 1 and sleeve pipe 2 by the cylndrical surface above them 3 and 4, have all-in-one-piece caliper plate 6 with it on the axle sleeve, the assembling unit structure of Gou Chenging connects by Short Cylinder Surface on it 7 and ransaxle like this, has anticreep convex shoulder 5 on the sleeve pipe.
In this assembling unit structure, cylndrical surface 3 and 4 connection adopt suitably that the temperature differential method of heating axle sleeve 1 realizes, both can obtain bigger magnitude of interference, do not destroy part precision again, do not change materials behavior, make to connect reliably, and coaxality is also higher relatively; Because caliper plate and axle sleeve are one, so the planeness of caliper plate and position degree also had assurance, can ensure braking ability effectively.
As the waste heat of the above-mentioned assembly parts overall structure that obtains by means of axle sleeve, be enclosed within on the shaft extension structure of ransaxle main body 8 fast and installations of exerting pressure vertically, still guaranteed the coaxality of the two, weld in the groove place that their connect then.
The utility model compared with prior art has following advantage or good effect:
1, because sleeve pipe cooperates with the connection of drive axle with axle sleeve, axle sleeve and all uses temperature differential method, thereby has and fill The cooperation that divides and positioning accuracy, stability and in conjunction with intensity; Simultaneously because axle sleeve and drive axle main body adopt same The material of kind of the trade mark, thereby should adjacent two weld parts after the welding stitch and the end-state of surrounding tissue can Keep close, mechanical performance is all secure, has reduced to greatest extent the defective that welding causes.
2, owing to adopt the combination structure to connect, eliminated the inside defective that forging, quenching bring, simultaneously, Improved the comprehensive utilization ratio of material, in addition since increased weld seam be subjected to the power cross section, strengthened intensity and Rigidity.
3, owing to the integral type axle sleeve that has adopted the band brake nipper, and with temperature difference cooperation welding, effectively protect Demonstrate,prove the plane degree of braking nipper friction face and with respect to the perpendicularity of datum clamp face, be conducive to improve system Moving performance.
