Abstract
The utility model discloses a mounting structure of semi -floating rear drive axle semi -axis and bearing frame, it includes semi -axis, semi -axis flange, bearing frame oil blanket, bearing frame, half bearing, bush and jump ring, on the semi -axis in proper order the pressure equipment have bearing frame, bush and jump ring, the inside pressure equipment of bearing frame has half bearing, and bearing frame oil blanket card is on the radial clearance of bearing frame and semi -axis, and half bearing holds with card spring clamping through the bush, and the inboard flange via hole periphery of semi -axis flange is equipped with the arc wall of round indent, and the arc wall passes through mid frequency quenching and forms the one deck quench -hardened case. The utility model discloses guarantee the the arc RADIUS of semi -axis flange root, reduced semi -axis flange root circular arc stress, increased semi -axis intensity, reduced the circular arc department stress of semi -axis flange root, reduced semi -axis fracture risk.
Description
Technical field
The utility model belongs to the technical field of auto parts and components, is related to a kind of semi-floating rear drive axle differential axle and bearing block
Mounting structure.
Background technology
Back axle is vitals in automobile, and semiaxis is the key components and parts in back axle, and the quality of its performance directly affects whole
The performance of car, and be possible to bring potential safety hazard, semiaxis can be divided into semi-floating, 3/4 float according to the difference of its force-bearing situation
Three kinds of formula, full floating, and wherein semifloating axle shaft is in addition to transmission torque, still suffer from vertical force, longitudinal force that wheel transmits and
Side force moment of flexure together, it can be seen that, the load that semifloating axle shaft is born is more complicated.Nowadays as car load carries negative
Lotus continues to increase, to the bearing torque and bearing requirements of semifloating axle shaft also more and more higher, and with wheel side structure it is more and more compacter,
Structure and dimensional requirement more and more higher to semifloating axle shaft；Because the structure and relative dimensions of semiaxis are designed, are heat-treated improper drawing
The semiaxis fracture damage sent out, and then the accident of half shaft pulley tire abjection happens occasionally when causing running car, seriously threatens occupant
Life security, existing class semifloating axle shaft because structure limit（Axle bearing is to tire centerline apart from little）And half shaft flange
Root arc radius are too little, cause circular arc stress excessive, half axle fracture, the security incident of related tire abjection easily occur.
Utility model content
The utility model purpose is to overcome the deficiencies in the prior art, there is provided a kind of semi-floating rear drive axle differential axle and bearing block
Mounting structure.
What the utility model was realized in：
The mounting structure of a kind of semi-floating rear drive axle differential axle and bearing block, it includes semiaxis, half shaft flange, bearing block oil
Envelope, bearing block, axle bearing, bushing and jump ring, are pressed with successively bearing block, bushing and jump ring, the bearing on the semiaxis
Seat is internal to be pressed with axle bearing, and bearing block oil sealing is stuck in the radial clearance of bearing block and semiaxis, and axle bearing passes through bushing
Clamp with jump ring, the flange via periphery on the inside of half shaft flange is provided with the deep-slotted chip breaker of a circle indent, deep-slotted chip breaker passes through mid frequency induction hardening
Form one layer of quench-hardened case.
Further, the hardened depth of deep-slotted chip breaker is more than 3mm.
Further, the arc radius of the deep-slotted chip breaker on the inside of half shaft flange are 12 mm, and the seam length of half shaft flange is
11.5mm。
The utility model first passes through frock and press-fits bearing block oil sealing, axle bearing on bearing block, then by itself and bushing
Press-fit on semiaxis, it is spacing using jump ring, the root of half shaft flange arranges a deep-slotted chip breaker for enclosing indent, recessed half method of principal axes of deep-slotted chip breaker
It is in blue end face, it is ensured that the arc radius of half shaft flange root and overall through mid frequency induction hardening, while in order to ensure that wall thickness adds
Major semiaxis seam；Seam extended length to 11.5mm, the hardened depth of deep-slotted chip breaker are more than 3mm, further reduce half method of principal axes
Blue root circular arc stress, increased semiaxis intensity.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of semiaxis of the utility model with size and half shaft flange；
In figure, semiaxis 1, bearing block oil sealing 2, bearing block 3, axle bearing 4, bushing 5, jump ring 6, half shaft flange 7.
Specific embodiment
Embodiment 1
The mounting structure of a kind of semi-floating rear drive axle differential axle and bearing block, it includes semiaxis 1, half shaft flange 7, bearing block
Oil sealing 2, bearing block 3, axle bearing 4, bushing 5 and jump ring 6, are pressed with successively bearing block 3, bushing 5 and jump ring on the semiaxis 1
6, axle bearing 4 is pressed with inside the bearing block 3, bearing block oil sealing 2 is stuck in the radial clearance of bearing block 3 and semiaxis 1, and half
Axle bearing 4 is clamped by bushing 5 and jump ring 6, and the flange via periphery of the inner side of half shaft flange 7 is provided with the deep-slotted chip breaker of a circle indent,
Deep-slotted chip breaker forms one layer of quench-hardened case by mid frequency induction hardening, and the hardened depth of deep-slotted chip breaker is more than 3mm.The arc of the inner side of half shaft flange 7
The arc radius of groove are 12 mm, and the seam length of half shaft flange 7 is 11.5mm.
The utility model first passes through frock and press-fits bearing block oil sealing 2, axle bearing 4 on bearing block 3, then by itself and lining
Set 5 press-fits on semiaxis 1, the flange via periphery of half shaft flange 7 inner side spacing using jump ring 6（That is the root of half shaft flange 7）
The deep-slotted chip breaker of a circle indent is provided with, in the end face of recessed half shaft flange 7 of deep-slotted chip breaker, it is ensured that the circular arc of the root of half shaft flange 7 half
Footpath, and it is overall through mid frequency induction hardening, while in order to ensure wall thickness plus major semiaxis seam；Seam length is lengthened to by 6.5mm
11.5mm, the hardened depth of deep-slotted chip breaker is more than 3mm, further reduces half shaft flange root circular arc stress, increased semiaxis strong
Degree, reduces the circular arc stress of half shaft flange root, reduces semiaxis risk of breakage.
