Abstract
The utility model relates to an inner oil-resistant plate-type oil seal with a dustproof cover and lips. The inner oil-resistant plate-type oil seal is characterized in that the lower part of a dust-blocking cover-type housing is fixedly connected with the oil seal, the bottom end of the oil seal is fixedly connected with a main lip, the front end of the dust-blocking cover-type housing is fixedly connected with an oil-resistant plate, and the bottom end of the oil-resistant plate is fixedly connected with an oil-resistant lip; an oil seal housing is designed to be of an outwards-wrapped iron shell structure, and the dustproof cover and the oil seal housing are integrated to realize the double functions of sealing and dust prevention; meanwhile, the oil-resistant plate with an oil-blocking lip is designed at the inner side of the oil seal, so as to avoid the opportunity of the direct contact of the seal lip with impurity iron scrap in gear oil and prevent damages on the seal lip, and due to the oil-resistant plate with the lip, the impact of an oil pressure on the seal lip is reduced.
Description
Technical field
The utility model relates to and a kind ofly carries dust-proof cover and with the interior oil-choking plate formula oil sealing of lip, belong to auto manufacturing, be applicable to all types of commercial car, mainly for all kinds of go-anywhere vehicle ransaxles, particularly half shaft sealing of wheel reductor and independent suspension drive axle main reducing gear.
Background technique
Go-anywhere vehicle drive axle wheel edge deceleration part and dependent hang main reducing gear of drive axle part, all adopt gear oil lubricated, its work under bad environment, the sealing at main reducing gear inner shaft, wheel reductor semiaxis place had both needed to seal gear oil, need again to prevent that dust, mud etc. from entering wheel limit, damage oil sealing.Due to structural configuration, the sealing Existential Space of this place's axle-shaft oil seal is little, and the problem of difficult arrangement arranges that double oil seal structure can increase pivot stud and tire distance, causes hard steering.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly carries dust-proof cover and with the interior oil-choking plate formula oil sealing of lip, it is designed to outsourcing iron casing structure by oil sealing shell, and dust-proof cover and oil sealing shell are made of one, and realizes sealing and dustproof dual functions; At the oil-choking plate of the oily lip of oil sealing inner side design one band gear, play and stop seal lip and the chance that impurity iron filings in gear oil directly contact simultaneously, prevent the damage to seal lip, the oil-choking plate with lip has reduced the impact of oil pressure to seal lip simultaneously.
The technical solution of the utility model is achieved in that and a kind ofly carries dust-proof cover and with the interior oil-choking plate formula oil sealing of lip, axle-shaft oil seal is comprised of main lip, oil resistance lip, oil-choking plate, oil sealing, dust-break bell-type shell, it is characterized in that: dust-break bell-type shell below is fixedly connected with oil sealing, oil sealing bottom is fixedly connected with main lip, dust-break bell-type shell front end is fixedly connected with oil-choking plate, and oil-choking plate bottom is fixedly connected with oil resistance lip; Inner shaft bearing, axle housing, inner shaft connect and are one, inner shaft one end is connected with bead by bead nut through bead, oil sealing base is fixedly connected with axle housing by bolt, its position is positioned at a side of close bead on axle housing, axle-shaft oil seal embeds the position between oil sealing base and bead and is fixedly connected with oil sealing base, on wheel reductor housing, be pressed with axle-shaft oil seal, outer semiaxis inserts wheel reductor housing, and outer semiaxis and wheel reductor housing contacting point seal by axle-shaft oil seal.
Good effect of the present utility model is that this project organization is very compact, in the working life of improving oil sealing, when improving whole bridge reliability, effectively shorten pivot stud and tire distance, make dependent hang ransaxle axial dimension and dwindle 20-30mm, independent suspension drive axle axial dimension dwindles 40-50mm, and makes to turn to light, increase independent suspension pendulum arm length, improve car load form smoothness.
Accompanying drawing explanation
Fig. 1 is independent suspension main reducing gear assembly structure figure of the present utility model.
Fig. 2 is wheel reductor assembly structure figure of the present utility model.
Fig. 3 is axle-shaft oil seal structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind ofly carry dust-proof cover and with the interior oil-choking plate formula oil sealing of lip, axle-shaft oil seal 1 is comprised of main lip 1-1, oil resistance lip 1-2, oil-choking plate 1-3, oil sealing 1-4, dust-break bell-type shell 1-5, it is characterized in that: dust-break bell-type shell 1-5 below is fixedly connected with oil sealing 1-4, oil sealing 1-4 bottom is fixedly connected with main lip 1-1, dust-break bell-type shell 1-5 front end is fixedly connected with oil-choking plate 1-3, and oil-choking plate 1-3 bottom is fixedly connected with oil resistance lip 1-2; Inner shaft bearing 2, axle housing 3, inner shaft 4 connect and are one, inner shaft 4 one end are connected with bead 5 by bead nut 7 through bead 5, oil sealing base 6 is fixedly connected with axle housing 3 by bolt 8, its position is positioned at a side of close bead 5 on axle housing 3, axle-shaft oil seal 1 embeds the position between oil sealing base 6 and bead 5 and is fixedly connected with oil sealing base 6, on wheel reductor housing 10, be pressed with axle-shaft oil seal 1, outer semiaxis 9 inserts wheel reductor housing 10, and outer semiaxis 9 seals by axle-shaft oil seal 1 with wheel reductor housing 10 contacting points.
Axle-shaft oil seal 1 is mainly comprised of with dust-break bell-type shell 1-5 and with the large parts of oil baffle 1-3 tri-that keep off oily lip 1-2 the oil sealing 1-4 with main lip 1-1.Concrete assembly structure has: on independent suspension main reducing gear, order is by inner shaft bearing 2 routinely, axle housing 3, inner shaft 4 are installed as one, oil sealing base 6 assemblies that press-fited axle-shaft oil seal 1 are arranged on axle housing 3, the construction bolt 8 of locking oil sealing base 6, again bead 5 is arranged on inner shaft 4, tightens bead nut 7.On wheel reductor, by press-fiting upper axle-shaft oil seal 1 on wheel reductor housing 10, insert outer semiaxis 9.
Due to the oil-choking plate with lip and outer dust-proof cover, its structure is very compact, effectively shortened axial dimension, when improving the working life and whole bridge reliability of oil sealing, effectively shorten pivot stud and tire distance, make dependent hang ransaxle axial dimension and dwindle 20-30mm, independent suspension drive axle axial dimension dwindles 40-50mm, and make to turn to light, and increase independent suspension pendulum arm length, improve car load form smoothness.
