The invention provides a drive axle hub, and aims to solve the problem that the service life of a bearing gland 16 is shortened because the structure of the bearing gland 16 at the end of the existing drive axle hub is easy to deform.
Referring to fig. 1 and fig. 2, in an embodiment of the present invention, the drive axle hub includes a bearing assembly, the bearing assembly includes a rotating shaft 8, and a bearing gland 16, a flange 6, a bearing gland 16, a fender 10, and a brake disc 9, which are sequentially disposed on the rotating shaft 8, and a bearing 5 disposed on the rotating shaft 8 is further included between the bearing gland 16 and the rotating shaft 6; the drive axle hub further comprises an axle housing 1, and one end of a rotating shaft 8 of the bearing assembly is installed in the axle housing 1; bearing gland 16 flange 6 orientation installing support 11 is installed to one side of axle housing 1, be provided with braking hose support 12 and manual brake cable support 13 on the installing support 11. According to the invention, the brake hose support 12 and the hand brake cable support 13 are arranged on the mounting support 11 and then arranged on the flange 6 of the bearing gland 16 through the mounting support 11, so that the phenomenon that the bearing gland 16 is extruded when the brake hose support 12 and the hand brake cable support 13 are directly arranged on the bearing gland 16 is avoided; the service life of the bearing gland 16 is improved and the structural stability is improved.
Specifically, referring to fig. 2, in the present embodiment, the brake hose bracket 12 and the handbrake cable bracket 13 are mounted on the mounting bracket 11, the mounting bracket 11 is a separate structure independent of the bearing cover 16 and the flange 6 of the bearing cover 16, and the mounting bracket 11 is mounted on the flange 6 of the bearing cover 16 by a fixing member. Through adopting foretell mounting structure, make braking hose support 12 and manual brake cable support 13 separate away from bearing gland 16 to when avoiding directly installing braking hose support 12 and manual brake cable support 13 on bearing gland 16 through the bolt, it is right bearing gland 16 causes the extrusion, leads to bearing gland 16 structure deformity, shortens bearing gland 16's life.
The mounting support 11 penetrates through the bearing gland 16 flange 6 and the bearing gland 16 through bolts 15, so that the mounting support 11, the bearing gland 16 flange 6 and the bearing gland 16 are fixed together. The mounting structure of the mounting support 11 is more stable by mounting the mounting support 11 on the bearing gland 16 flange 6 and the bearing gland 16; meanwhile, the flange 6 of the bearing gland 16 and the bearing gland 16 can share the pressure applied by the mounting support 11, so that the extrusion force on the bearing gland 16 and the flange 6 of the bearing gland 16 is further reduced, and the whole structure is more stable.
By installing the brake hose bracket 12 and the hand brake cable bracket 13 on the installation support 11 and installing the installation support 11 on the bearing gland 16 flange 6 and the bearing gland 16, the hand brake cable bracket 13 and the brake hose bracket 12 concentrate the force on the installation support 11, and the pressure borne by the installation support 11 can be dispersed from the bearing gland 16 and the bearing gland 16 flange 6, so that the installation structure greatly improves the structural stability at the hub end of the drive axle.
The brake hose bracket 12 and the hand brake cable bracket 13 may be detachably and fixedly mounted on the mounting support 11, and of course, may also be non-detachably and fixedly mounted on the mounting support 11. The brake device is detachably mounted on a mounting support 11 through a bolt, or the brake hose bracket 12 and the hand brake cable bracket 13 are integrated; and is not particularly limited herein.
The mounting bracket 11 is plate-shaped, and the plate-shaped mounting bracket 11 is used for receiving the brake hose bracket 12 and the hand brake cable bracket 13. The mounting support 11 is designed to be a plate-shaped structure, so that the concentration of the extrusion force of the brake hose bracket 12 and the hand brake cable bracket 13 on the mounting support 11 can be reduced.
Further, the bearing 5 is a double row tapered roller bearing. By adopting the double-row tapered roller bearing, the bearing can bear larger axial force, and the problem that the bearing fails early due to insufficient capability of resisting the axial force is avoided.
In a further preferred embodiment, the brake hose bracket 12 is welded to the mounting bracket 11. In order to further optimize the structure of the bearing gland 16 and the flange 6 of the bearing gland 16, the brake hose bracket 12 is directly welded on the mounting support 11, and the mounting procedures are reduced.
Further, a welding nut 14 for installing the hand brake cable bracket 13 is welded on the installation support 11. By welding the weld nut 14 to the mount bracket 11, the assembly process of parts and the cost of parts are reduced.
In another embodiment, a fastening member 4 sleeved on the rotating shaft 8 is arranged between the rotating shaft 8 and the flange 6 of the bearing gland 16, and the fastening member 4 is arranged near the bearing 5 to prevent the bearing 5 from loosening. Wherein, the fastener 4 and the bearing 5 are in interference fit.
Further, the fastener 4 comprises a fastening sleeve (not marked) and a gear ring (not marked), and the gear ring and the fastening sleeve are of an integrated structure formed by cold extrusion forming. The ring gear is the ABS ring gear, because the ABS ring gear generally adopts powder metallurgy shaping, and the adapter sleeve adopts forging to form, and ABS ring gear and adapter sleeve generally are interference fit, consequently, need accomplish on the press ABS ring gear with the cooperation of adapter sleeve, and when the pressure equipment, the ABS ring gear is easy by the iron fillings powder of scraping department, if the clearance is unclean through probably making iron fillings powder oil feed oil seal 3 lips, leads to 3 oil leakages of oil seal. Therefore, in the embodiment, the fastening sleeve and the gear ring are designed into an integral structure, and are formed through cold extrusion, so that scrap iron generated during press mounting of the gear ring is avoided, the risk of oil leakage of the oil seal 3 is reduced, and the press mounting process and press mounting equipment of the gear ring are reduced.
Further, an oil seal 3 is arranged between the fastener 4 and the flange 6 of the bearing gland 16; and an oil return hole 2 is formed in the end face, close to one end of the axle housing 1, of the flange 6 of the bearing gland 16, so that oil at a gear is prevented from being accumulated on the matching surface of the oil seal 3 and the fastener 4. Specifically, when the vehicle runs on a side road surface, the lubricating oil flows to the flange 6 oil seal 3 cavity of the bearing gland 16; when the vehicle runs on a normal road surface again, lubricating oil can flow back to the main axle reduction package through the designed oil return hole 2, and the phenomenon that gear oil is accumulated on the matching surface of the oil seal 3 and the fastening piece 4 for a long time to cause oil leakage of the oil seal 3 is avoided.
In order to further optimize the structure of the splash guard 10, the splash guard 10 is fastened to the bearing cover 16 by means of a hexagon head bolt 7. The number of the hexagon head bolts 7 is four, and the four hexagon head bolts 7 are fastened with the bearing gland 16, so that the fastening of the bearing gland 16 by fastening bolts is avoided, and the fastening reliability of the whole bearing assembly is improved.
In addition, in order to achieve the above object, the present invention further provides a vehicle including the drive axle hub as described above. Since the automobile comprises the drive axle hub, all the beneficial effects of the drive axle hub are achieved, and therefore, the description is omitted.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
