Abstract
The utility model relates to an axle wheel locking mechanism which is accurate in locking and locating, stable in bearing pretightening force adjustment, convenient to install, quick and reliable in locking mode. The axle wheel locking mechanism comprises a nut collar, a locking nut and a snap ring. A clamping pin is arranged on the inner diameter of the nut collar. A circle of first through holes are formed in the circumferential direction of nut collar. A plurality of second through holes are formed in a flange ring of the locking nut. A clamping groove is formed in the circumferential surface of the nut. A hooked clamping bar is arranged on the snap ring. When the axle wheel locking mechanism is assembled, a drive axle shaft head is sleeved with the nut collar, the clamping pin of the collar is aligned with the clamping groove in the shaft head, after the locking nut is installed, the hooked clamping bar on the snap ring sequentially penetrates through the second through holes and the first through holes and then hook the nut collar, and eventually the snap ring is clamped in the clamping groove in the locking nut. Preferably, the second through holes are three oblong holes and all formed in a semicircular ring of the flange ring of the locating nut, and the first through holes are rectangular through holes.
Description
Technical field
The utility model relates to a kind of tight latch mechanism, particularly the tight latch mechanism on a kind of vehicle bridge wheel limit.
Background technique
The validity of the locked position of vehicle bridge wheel limit locking nut is very large to vehicle bridge wheel limit performance impact.If the locking nut pine moves back, or the structure due to locking nut can not guarantee to be locked in desirable position while installing, and can affect performance and the stability thereof of vehicle bridge.
At present, single-stage bridge wheel limit adopts the tight latch mechanism of double nut more, comprises internal locking nut, locking locking plate and outer locking nut.But the restriction due to locking nut structure, inside and outside locking nut only has six grooves, while reaching desirable screw-down torque when two locking nuts is installed, often because two locking nut draw-in grooves can't be corresponding with the tooth that loosens locking plate, carry out pine and move back or apply larger moment and have to fall locking nut, thereby affected the usability on vehicle bridge wheel limit.
The model utility content
For deficiency of the prior art, the utility model provides a kind of locking and positioning accurate, and the bearing pre-fastening adjustment is stable, and it is convenient to install, the tight latch mechanism in locking mode reliable vehicle bridge wheel limit.
In order to address the above problem, this kind of tight latch mechanism in vehicle bridge wheel limit, comprise nut collar, locking nut and snap ring, and the internal diameter of this nut collar is provided with card base, it is characterized in that: along circle first through hole that is circumferentially with of nut collar; The flange ring of this locking nut is provided with a plurality of the second through holes, and the side face of this nut is provided with draw-in groove; This snap ring is provided with hook-shaped card article;
During assembling, nut collar is inserted on the ransaxle spindle nose, and the draw-in groove on the card base alignment spindle nose on this packing ring, after the locking nut of packing into, hook-shaped card article on snap ring, successively through after the second through hole and the first through hole, hooking nut collar, is finally snapped in snap ring in the draw-in groove on locking nut.
Preferably, described the second through hole is three slotted holes, and this second through hole all is located on the semicircular ring of locking nut flange ring; Described the first through hole is rectangular through-hole.
The beneficial effects of the utility model are: this tight latch mechanism has guaranteed definite value adjustment bearing pre-fastening, and mounting process is simple; Tight latch mechanism thickness reduction, save space, and reduced the use of material.
The accompanying drawing explanation
The structural representation of facing that Fig. 1 is nut collar of the present utility model;
The structural representation of facing that Fig. 2 is locking nut of the present utility model;
The structural representation of facing that Fig. 3 is snap ring of the present utility model;
The assembly structure schematic diagram that Fig. 4 is the tight latch mechanism in vehicle bridge of the present utility model wheel limit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
This kind of tight latch mechanism in vehicle bridge wheel limit, comprise nut collar 1, locking nut 2 and snap ring 3.
As shown in Figure 1, the internal diameter of this nut collar is provided with card base 11, this packing ring be circumferentially with circle first a through hole 1a, this through hole is preferably rectangular through-hole.
As shown in Figure 2, this locking nut 2 is the hexagon head locking nut, and its side face is provided with the draw-in groove (not shown), and flange ring is provided with a plurality of the second through hole 2a.For ease of assembling with adjust, the second through hole 2a is three slotted holes, and three the second through hole 2a all are located on the same semicircular ring of locking nut flange ring,
As shown in Figure 3, it is relative that this snap ring 3 is provided with ，Yu inserted part, inserted part, is provided with hook-shaped card article 31, and the width of this hook-shaped card article guarantees to pass above-mentioned two through holes, and the free end of card article is provided with grab, for blocking nut collar 1.
As shown in Figure 4, during assembling, at first nut collar 1 is inserted on the ransaxle spindle nose, draw-in groove on card base alignment spindle nose on this packing ring, next assembles locking nut 2, and screw-down torque is as requested tightened, and afterwards the hook-shaped card article 31 on snap ring is hooked to nut collar through its grab after the second through hole 2a and the first through hole 1a successively, finally the inserted part on snap ring is snapped in the draw-in groove on locking nut 2, complete assembling.This structure has guaranteed definite value adjustment bearing pre-fastening, and mounting process is simple; Tight latch mechanism thickness reduction, save space, and reduced the use of material.
It should be noted that; embodiment is only to the explanation of technical solutions of the utility model and explanation; should not be understood as the restriction to technical solutions of the utility model; any employing the technical solution of the utility model and only do local change, must fall in protection domain of the present utility model.
