Abstract
The utility model discloses an axle housing of a rear axle, in particular to a three-section axle housing of a rear axle of a mini-vehicle. The utility model provides an axle housing of a rear axle of a mini-vehicle, the axle housing is used for enhancing strength at weld joints and comprises a rear axle oil tank assembly, axle sleeves and rear axle housing reinforcing blocks, wherein the axle sleeves are welded at two ends of the rear axle oil tank assembly, the rear axle housing reinforcing blocks are connected on the rear axle oil tank assembly and the axle sleeves. The rear axle housing reinforcing blocks are connected on the rear axle oil tank assembly and the axle sleeves so as to perform auxiliary connection among the rear axle oil tank assembly and the axle sleeves; thereby increasing the connection strength among the rear axle oil tank assembly and the axle sleeves and preventing the deformation and fatigue fracture of the annular weld joints at the connecting parts. The rear axle housing reinforcing block can be provided with U-shaped grooves so as to be conveniently glued and matched with the circular rear axle oil tank assembly and the axle sleeves.
Description
Technical field
The utility model relates to a kind of rear axle case, the little car rear axle case of especially a kind of syllogic.
Background technology
For traditional little car syllogic axle housing, its axle tube all is connected by the ring-type weld seam with the back axle fuel tank assembly, because the insufficient strength of welding is stable, in long-term heavy duty, under the overload situation, the axle housing easy deformation, make back axle normal operating conditions of each part in transmission process change, the easy like this planetary wheel that occurs, the axle side gear abnormal sound, gear is ablated, phenomenons such as gear wheel shaft fractures, after also having the axle housing bending, the Internal and external cycle of axle bearing will form bigger angle, and temperature can rise rapidly under fast state, cause the bearing inordinate wear, reduce service life, faults such as axle-shaft oil seal leakage of oil.These faults all have direct relation with distortion of ring-type commissure even fracture by fatigue, and therefore, the rigidity and the intensity that improve rear axle case are just most important.
The utility model content
Technical problem to be solved in the utility model provide a kind of reinforced weld place intensity and improve whole axle housing rigidity little car rear axle case.
Little car rear axle case that its technical matters that solves the utility model adopts, comprise the back axle fuel tank assembly, be welded on the axle tube at back axle fuel tank assembly two ends, also comprise the rear-axle casing boss, described rear axle case boss is connected on back axle fuel tank assembly and the axle tube.
Further be, the rear-axle casing boss is provided with U-lag, and described U-lag is set in back axle fuel tank assembly and axle tube weld.
Further be that the rear-axle casing boss is welded on back axle fuel tank assembly and the axle tube.
Further be that the segmentation of rear-axle casing boss is welded on back axle fuel tank assembly and the axle tube.Reduce welding stress concentration with this.
The beneficial effects of the utility model are: utilize the rear-axle casing boss to be connected on back axle fuel tank assembly and the axle tube, can assist and connect back axle fuel tank assembly and axle tube, this just makes back axle fuel tank assembly and axle tube bonded assembly intensity increase, thereby prevents the circumferential weld distortion even the fracture by fatigue of junction.The rear-axle casing boss can be provided with U-lag, thus the applying of convenient with circular back axle fuel tank assembly and axle tube coupling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the structural representation of rear-axle casing boss;
Parts, position and numbering among the figure: axle tube 1, rear-axle casing boss 2, back axle fuel tank assembly 3, U-lag 21.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model comprises back axle fuel tank assembly 3, is welded on the axle tube 1 at back axle fuel tank assembly 3 two ends, also comprises rear-axle casing boss 2, and described rear-axle casing boss 2 is connected on back axle fuel tank assembly 3 and the axle tube 1.Because back axle fuel tank assembly 3 is connected with two axle tubes 1 usually, therefore, rear-axle casing boss 2 is selected two usually for use, is installed in the weld of two place's axle tubes 1 and back axle fuel tank assembly 3 respectively.Rear-axle casing boss 2 is implemented the segmentation welding by being welded to connect on back axle fuel tank assembly 3 and axle tube 1, reduces welding stress.Rear-axle casing boss 2 can be set to different shape, can assist thus and connect back axle fuel tank assembly 3 and axle tube 1, strengthen Joint strenght and rigidity between back axle fuel tank assembly 3 and the axle tube 1, improve the torsional fatigue strength of axle housing, therefore can prevent the distortion and the fatigue cracking of the ring-type position while welding of back axle fuel tank assembly 3 and axle tube 1 by actv., thereby increase the service life of whole little car rear axle case.
For the ease of rear-axle casing boss 2 is installed, as shown in Figure 3, rear-axle casing boss 2 is provided with U-lag 21, and described U-lag 21 is set in back axle fuel tank assembly 3 and axle tube 1 weld.Back axle fuel tank assembly 3 is rounded usually with axle tube 1, adopts the rear-axle casing boss 2 of U-lag 21 better to fit, and rear-axle casing boss 2 stressed more even avoids occurring stress concentration; The location is also easy when mounted, and is therefore easier for installation.
