Abstract
The utility model relates to a hub oil seal with a pre-blocking lip opening and a lining ring of an automobile drive axle, belonging to the field of automobile parts and aiming at designing the hub oil seal with the pre-blocking lip opening and the lining ring of the automobile driving axle which facilitates arrangement of an automobile wheel-edge speed-reducing drive axle, is applicable to thin-oil lubrication and improves the reliability. The hub oil seal is characterized in that the lining ring is provided with an outer oil seal and an inner oil seal in sequence, wherein the inner oil seal is provided with an inner oil retaining ring. In the hub oil seal, the structure is simple and relatively compact, and the disassembling process is simple; the lining ring of the oil seal can reduce the possibility of damage during the transportation and installation of the lip opening of the oil seal; and the hub oil seal is applicable to thin-oil lubrication, improves the reliability, has low process requirement on a seat ring of the oil seal, is easy to arrange a wheel-edge speed reducer, is applicable to various commercial vehicles and passenger vehicles, is mainly used for the wheel-edge speed-reducing drive axle and particularly relates to an assembly of the hub oil seal of the wheel-edge speed-reducing drive axle.
Description
Technical field
The utility model belongs to the auto-parts field.
Background technique
For commercial car hub reduction ransaxle, hub bearing generally adopts the gear oil in the hub reduction gear mechanism to be lubricated, i.e. thin oil lubricant at present.And general use of hub reduction ransaxle carried big, road conditions rugged environment.Therefore the hub oil seal reliability had very high requirement.Present domestic general employing boxlike oil sealing or dual-oil seal structure.Boxlike oil seal structure complexity, but compact structure have higher requirements to dismounting and anufacturability; Another kind of dual-oil seal is simple in structure, but the size that takes up room is bigger, does not have the pre-barrier functionality of oil pressure of boxlike oil sealing.Two kinds of structures have pluses and minuses mutually.Because the diversity that the ransaxle car load is arranged, more than two kinds of structures still have certain narrow limitation.
Summary of the invention
Order of the present utility model ground is the layout for ease of car-wheel limit deceleration bridge, is suitable for thin oil lubricant, and improves its reliability, designs the hub oil seal of a kind of automobile drive axle band desire resistance lip and grommet.
The utility model is equipped with outer oil seal and inner oil seal successively on inner bushing ring, interior flinger ring is housed on inner oil seal.
Simple in structure, the relative compact of the utility model, dismounting process is simple.The oil sealing grommet more is applicable to narrow type or split type oil sealing seat ring, also can reduce the possibility that oil seal lip transportation and installation process are damaged.Oil seal assembly is suitable for thin oil lubricant, and improves its reliability, and is low to oil sealing seat ring technological requirement.Being easy to wheel reductor arranges.
Be applicable to all types of commercial car, passenger car, be primarily aimed at the hub reduction ransaxle, particularly a kind of hub reduction ransaxle hub oil seal assembly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is installed and used schematic representation.
Embodiment
The utility model is equipped with outer oil seal 3 and inner oil seal 2 successively on inner bushing ring 4, on inner oil seal 2 be equipped with in flinger ring 1.
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, a kind of car-wheel limit deceleration bridge hub oil seal is by interior flinger ring 1, inner oil seal 2, and outer oil seal 3, inner bushing ring 4 is formed.Assembly structure is successively hub bearing 7, hub oil seal assembly 6 to be fitted in the endoporus of wheel hub 5, wheel hub is fitted on the axle tube 8 again, and hub oil seal is cooperated with oil sealing seat ring 9.
Because 2 are equipped with interior flinger ring 1 on the inner oil seal of hub oil seal assembly, play the effect that pre-oil resistance is pressed; Inner bushing ring 4 can protect oil seal lip transportation and installation process not to damage, and more is applicable to narrow type or split type oil sealing seat ring.Its simple in structure, relative compact, dismounting process is simple.Be suitable for thin oil lubricant, and improve its reliability, low to oil sealing seat ring technological requirement.Being easy to wheel reductor arranges.
Claims (1)
