According to an aspect of the present utility model, it is provided that a kind of wheel limit locking mechanism, this is taken turns limit locking mechanism and includes propping up
Hold axle, be arranged at the axle bearing mount portion of the radial outside of support shaft and be arranged at the axially external locking screw of axle bearing mount portion
Female.This is taken turns limit locking mechanism and also includes being arranged at the axially external locking pressure plate of described locking nut, and by described locking pressure
Plate is fixed to the hold-down bolt on described axle bearing mount portion.
Preferably, described locking pressure plate is formed with multiple the first through hole passed through for described hold-down bolt, and
Multiple second through hole or screwed hole it has been correspondingly formed on described axle bearing mount portion.
Preferably, described locking pressure plate includes that described protuberance is in institute towards the protuberance that described axle bearing mount portion is prominent
State when hold-down bolt is tightened against described axle bearing mount portion.Described first through hole may be formed in described protuberance.
It is further preferred that the plurality of first through hole and the plurality of second through hole or screwed hole the most uniformly divide
Cloth.
In one embodiment, the quantity of the plurality of first through hole and the plurality of second through hole or screwed hole is
Four.
In one embodiment, described axle bearing mount portion is that the gear ring with hub reduction gear is fixed the gear ring being connected and propped up
Frame, described gear ring support is connected with described support shaft by spline.
In one embodiment, described support shaft is the axle tube being set on semiaxis.
According to another aspect of the present utility model, it is provided that a kind of wheel edge deceleration driving axle, this wheel edge deceleration driving axle bag
Include driving axle housing, wheel hub and hub reduction gear, also include taking turns limit locking mechanism as above.
In this article, " axially ", " radially " and " circumferential " refer to axial, the footpath for wheel edge deceleration driving axle
To and circumference.
According to this utility model, axially external at locking nut is provided with locking pressure plate, and this locking pressure plate is by compressing spiral shell
Bolt is fixed on axle bearing mount portion.Therefore, reliably prevent locking nut in use occurs pine to move back such that it is able to really
Protect the pretightning force of hub bearing, it is to avoid occur hub bearing to damage, the fault such as tooth, leakage of oil beaten by gear.
Accompanying drawing explanation
Fig. 1 is the axial side view of the wheel edge deceleration driving axle according to this utility model one embodiment；
Fig. 2 is the sectional view of the axial end portion of wheel edge deceleration driving axle shown in Fig. 1, it is shown that wheel limit locking mechanism.
Detailed description of the invention
The utility model is further described to combine a specific embodiment with reference to the accompanying drawings.
Fig. 1 illustrates the axial side view of the wheel edge deceleration driving axle according to this utility model one embodiment.Fig. 2 is Fig. 1 institute
Show the sectional view of the axial end portion of wheel edge deceleration driving axle, it is shown that wheel limit locking mechanism.
Wheel edge deceleration driving axle mainly includes driving axle housing, differential mechanism, the main reducing gear as first order reducing gear, wheel
Hub and the planetary gear type hub reduction gear as second level reducing gear.As in figure 2 it is shown, the gear ring 1 of hub reduction gear passes through
Gear ring support 2 (gear ring base) is connected with the axle tube 3 constituting a driving axle housing part.Specifically, gear ring support 2 can pass through spiral shell
Tether and receive gear ring 1, and axle tube 3 can be connected to by spline.It addition, although not shown in, but art technology
Personnel are it is understood that the central gear of hub reduction gear can be connected with semiaxis by spline and rotate with semiaxis, and supporting planetary
The planet carrier of gear can be connected with wheel hub by bolt.It is delivered to semiaxis through main reducing gear, then from the power of differential mechanism output
It is delivered to wheel hub through central gear, planetary gear, planet carrier, thus drives wheel to rotate.Fig. 2 eliminates the diagram of wheel hub,
It is shown only for two taper roll bearings of support cage.Wheel hub is bearing in gear ring support 2 by the hub bearing 4 in left side
On, and wheel hub is bearing on axle tube 3 by the hub bearing 5 on right side.
The axially external end (left end in Fig. 2) of axle tube 3 is provided with threaded portion, and locking nut 6 is screwed in this
On threaded portion, push gear ring support 2 along the direction (along towards right direction in Fig. 2) towards drive axle central part, thus to hub spindle
4,5 offer axial pre tightening forces are provided.For preventing locking nut 6 pine from moving back, set in axially external (left side in Fig. 2) of locking nut 6
It is equipped with locking pressure plate 7.The cross section of locking pressure plate 7 is circular, and axle tube 3 extends through its central opening.Locking pressure plate 7
It is fixed on gear ring support 2 by hold-down bolt 8.As it is shown in figure 1, four hold-down bolts 8 are uniformly distributed circumferentially, they are from axle
Pass the through hole formed in locking pressure plate 7 and the through hole being correspondingly formed on gear ring support 2 laterally, and at gear ring support
The axially inner side nut of 2 fastens.As in figure 2 it is shown, locking pressure plate 7 axially inner side (right side in Fig. 2) be formed towards
The prominent protuberance 9 of gear ring support 2, the through hole passed for hold-down bolt 8 is formed in this protuberance 9.Embodiment in diagram
In, the quantity of protuberance 9 is also four.When hold-down bolt 8 is tightened, protuberance 9 is against gear ring support 2.
Industrial applicibility
According to of the present utility model take turns limit locking mechanism be particularly suited for engineering truck, such as wheel loader, but be not limited to
This.It is also applied for other any vehicles needing to carry out taking turns limit locking.
During use, after the gear ring of wheel hub and hub reduction gear and gear ring support 2 are set on axle tube 3, will
Locking nut 6 is tightened on the threaded portion of axle tube 3, makes the right side of locking nut 6 be close on gear ring support 2.Then,
Locking pressure plate 7 is set on axle tube 3, and makes four through holes in locking pressure plate 7 and the respective through hole on axle tube 3
Alignment.From the axially external through hole locking pressure plate 7 and the through hole on axle tube 3 that hold-down bolt 8 is inserted through, and at tooth
The axially inner side nut of coil support 2 fastens so that protuberance 9 is against gear ring support 2.Foot can be provided by four hold-down bolts
Enough big thrusts, even if locking nut 6 loosens also cannot retreat, thus ensure reliable lock.
Should be appreciated that the quantity of hold-down bolt is not limited to four, it is also possible to be other quantity.It addition, on axle tube 3
Through hole can also replace with screwed hole, thus can omit the clamp nut of axle tube 3 axially inner side.
Limit locking mechanism is taken turns according to of the present utility model, owing to being provided with locking pressure plate 7 in the axially external of locking nut 6,
And this locking pressure plate 7 is fixed on gear ring support 2 by hold-down bolt 8, using so reliably prevent locking nut 6
During occur pine move back.It is accordingly possible to ensure the pretightning force of hub bearing, it is to avoid occur hub bearing to damage, gear plays tooth, leakage
The faults such as oil.
For it is obvious for a skilled person that, in the case of without departing from scope of the present utility model or spirit,
Can various modification can be adapted and modification to foregoing disclosed embodiment.According to disclosed in this specification to reality of the present utility model
Trampling, other embodiments of the present utility model are apparent to those skilled in the art.This specification and disclosure thereof
Example should be considered to be only exemplary, true scope of the present utility model is specified by claims and equivalent thereof.
