Abstract
The invention relates to an adjusting nut with double oil seals for a through axle of an automobile drive axle, belonging to automobile drive axles. The adjusting nut is characterized by comprising a nut body and the oil seals, wherein the nut is of a circular shape, the left part of the outer circular surface of the nut body is provided with external screw threads, and the circumference of the right end part of the outer circular surface of the nut body is uniformly provided with locking notches which are used for locking the adjusting nut or mounting and dismounting the adjusting nut with a special tool. The central hole of the nut body is manufactured smoothly, the left oil seal and the right oil seal are in interference fit with each other and pressed in the central hole of the nut body, thus the mouth of each oil seal towards left, the sealing effect is good, the oil leakage possibility and dust invasion possibility are small, and the service life is prolonged.
Description
Technical field
The invention belongs to automobile drive axle, especially relate to the adjustment nut that a kind of automobile drive axle connects axle.
Technical background
Existing automobile drive axle connects axle and generally all adds end cap and tighten, and the center of this end cap only uses an oil sealing sealing gear oil, and it is loosening that this structure often makes the bearing that connects on the axle occur easily, and poor sealing, easy oil leakage.
Summary of the invention
The objective of the invention is to propose the adjustment nut that a kind of automobile drive axle that has dual-oil seal connects axle, to connect the axle with axle housing between by the adjustment nut be connected, so both realized that perforation axle bearing impacting force was adjustable and compress even, good sealing effect again, not easy oil leakage, be difficult for into dust, increase the service life.
The object of the present invention is achieved like this, a kind of automobile drive axle that has dual-oil seal connects the adjustment nut of axle, the adjustment nut that it is characterized in that this automobile drive axle that has dual-oil seal perforation axle mainly is made up of nut body and oil sealing, this nut body is ring, and offer outside thread and offer the stop notch at the right part of nut body outer ring surface circumference uniform distribution at the left part of nut body outer ring surface, be used for that this adjusts nut to this adjustment nut stop or with the special tool dismounting, the center hole of this nut body is made smooth, and the lip that interference fit press-fits left and right sides oil sealing and makes each oil sealing in the center hole of this nut body is all towards a left side.
During installation, this ransaxle that has dual-oil seal is connected axial adjustment nut screw in the perforation tapped hole on the axle housing, and compress the deep groove ball bearing that connects on the axle, corresponding auger shell hole and locking plate is installed on axle housing, earlier the lower end of locking plate is snapped in the stop notch on this nut body, the fixed stop that tights a bolt again sheet like this, connects axle being installed on the axle housing tightly, be difficult for loosening, and left and right sides oil sealing sealing is effective, not easy oil leakage, is difficult for into dust, long service life.
The automobile drive axle that has dual-oil seal proposed by the invention connects the adjustment nut of axle, and is in light weight, fastening effective, and it is loosening that the perforation axle is difficult for, and the dual-oil seal good sealing effect, and not easy oil leakage is difficult for into dust, long service life.
Now the adjustment nut that in conjunction with the accompanying drawings and embodiments automobile drive axle that has dual-oil seal proposed by the invention is connected axle is described further.
Description of drawings
Fig. 1 is the main cross-sectional schematic that the automobile drive axle that has dual-oil seal proposed by the invention connects the adjustment nut of axle.
Fig. 2 is that schematic representation is looked on the right side that the automobile drive axle that has dual-oil seal proposed by the invention connects the nut body in the adjustment nut of axle.
Fig. 3 is the main cross-sectional schematic after the installation of the automobile drive axle that the has dual-oil seal proposed by the invention adjustment nut that connects axle.
Among Fig. 1, Fig. 2, Fig. 3:
1, nut body 2, oil sealing 3, stop notch 4, axle housing 5, bolt 6, locking plate 7, deep groove ball bearing 8, perforation axle
Embodiment
From Fig. 1, Fig. 2, among Fig. 3 as can be seen: a kind of automobile drive axle that has a dual-oil seal connects the adjustment nut of axle, the adjustment nut that it is characterized in that this automobile drive axle that has dual-oil seal perforation axle mainly is made up of nut body 1 and oil sealing 2, this nut body 1 is ring, and the left part at nut body 1 outer ring surface is offered outside thread and is offered stop notch 3 at the right part circumference uniform distribution of nut body 1 outer ring surface, be used for to this adjustment nut stop or with this adjustment nut of special tool dismounting, the center hole of this nut body 1 is made smooth, and the lip that interference fit press-fits left and right sides oil sealing 2 and makes each oil sealing 2 in the center hole of this nut body 1 is all towards a left side.
During installation, the ransaxle that earlier this is had a dual-oil seal connects the axial adjustment nut and screws in the perforation tapped hole on the axle housing 4, and compress the deep groove ball bearing 7 that connects on the axle 8, corresponding auger shell hole and locking plate 6 is installed on axle housing 4, promptly earlier the lower end of locking plate 6 is snapped in the stop notch 3 on this nut body 1,5 fixed stop sheets 6 again tight a bolt, like this, connect axle 8 being installed on the axle housing 4 tightly, be difficult for loosening, and oil sealing 2 good sealing effects in the left and right sides, are difficult for into dust, long service life at not easy oil leakage.
