Abstract
The utility model discloses an anti-loose driving shaft locking structure. The anti-loose drive shaft locking structure comprises a wheel hub unit and a drive shaft arranged in a wheel hub unit shaft hole, wherein the wheel hub unit and the drive shaft are fixed by a self-locking nut, the self-locking nut comprises a nut which are in threaded fit with the drive shaft and a nylon pad arranged on at least partial of the inner wall of the nut, and a cotter pin is arranged on the drive shaft and closely attached to the outer side of the nut. The nylon pad is preferably a nylon ring arranged along the periphery of the inner wall of the nut, and the nylon ring is preferably arranged on the inner wall of the nut adjacent to the end of the cotter pin. According to the locking structure of the anti-loose driving shaft locking structure, the nylon pad is arranged on the inner wall of the nut, the outer threads of the drive shaft can have a 'tapping' function to the nylon pad of the inner wall of the nut when the nut is fastened, the fact that the nut has the self-locking and anti-loose functions is only because the existence of the nylon pad, and the fact that failure and falling off of the nut in particular cases causes the falling off of the drive shaft is avoided effectively because of the existence of the cotter pin.
Description
Technical field
The utility model relates to a kind of drive shaft device of car drivetrain, more precisely, relates to the locking device on a kind of this axle drive shaft.
Background technology
Axle drive shaft is as one of the important device of transmission of power on the car, and its performance will directly have influence on dynamic economics and the traveling comfort of car load.Wherein, the performance of drive shaft device locking mechanism will have influence on life-span of efficient, hub bearing of whole transmission system and car load noise etc.Locking mechanism in the market mainly contains following several: bullet pad+fluted nut+spring cotter; The axle drive shaft flange nut of slotting+lock; Plain cushion+self lock nut; Axle drive shaft negative thread+bolt.The structure of its pad+fluted nut of being hit by a bullet+spring cotter as shown in Figure 1, comprise the axle drive shaft 4 that passes hub 3, by bullet pad 6 and fluted nut 7 axle drive shaft 4 and hub 5 are combined together, spring cotter 2 passes the purpose that fluted nut 7 and axle drive shaft 4 reach locking.Above-mentioned fit structure is not owing to there is the function of self-locking, in the process of driving, if the bullet pad lost efficacy or nut loosening then can cause the bad of locking, thereby causes the appearance of hub corresponding failure.
The utility model content
In order to solve the problems such as hub fault rate height that cause owing to the axle drive shaft locking effect is not good that exist in the prior art, the utility model provides a kind of locking mechanism of locking axle drive shaft.
For achieving the above object, the technical solution of the utility model is: a kind of locking mechanism of locking axle drive shaft, comprise hub and be assemblied in the interior axle drive shaft of hub axis hole, described hub and axle drive shaft are fixed by self lock nut, comprise the nut that cooperates with drive shaft screw thread, and be arranged on the nylon cushion on nut at least a portion inwall.
Preferably, described nylon cushion is the nylon ring along the circumference setting of nut inner wall.
Preferably, described nylon ring is arranged on an end of adjacent openings pin on the nut inner wall.
Preferably, the outside of being close to nut on the described axle drive shaft also is provided with spring cotter.
Locking mechanism of the present utility model, the inwall of nut is provided with nylon cushion, and in urgent, the outside thread on the axle drive shaft can play the effect of " tapping " to the nylon cushion on the nut inner wall, also just because of the existence of this nylon cushion, ability is so that nut has played self-locking and locking effect; The existence of spring cotter has prevented from coming off because of the lost efficacy axle drive shaft that causes that comes off of extraordinary circumstances lower nut effectively.
Description of drawings
Fig. 1 is the locking mechanism scheme drawing of drive shaft device in the prior art.
Fig. 2 is the scheme drawing of the utility model locking mechanism.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
With reference to figure 2, the locking mechanism of a kind of locking axle drive shaft of the present utility model, comprise hub 3 and be assemblied in the interior axle drive shaft 4 of hub axis hole, described hub 3 and axle drive shaft 4 are fixed by self lock nut, described self lock nut comprises the nut 1 that cooperates with drive shaft screw thread, and is arranged on the nylon cushion 5 on nut 1 at least a portion inwall; The fit system of nylon cushion and nut can adopt the groove engaging, also can adopt other structures known in the art; Also can add certain airtight dose in the nut 1.The outside of being close to nut on the described axle drive shaft 4 also is provided with spring cotter 2.
Locking mechanism of the present utility model, the inwall of nut 1 is provided with nylon cushion, and in urgent, the outside thread on the axle drive shaft 4 can play the effect of " tapping " to the nylon cushion on the nut inner wall, also just because of the existence of this nylon cushion, ability is so that nut has played self-locking and locking effect; The existence of spring cotter 2 has prevented from coming off because of the lost efficacy axle drive shaft that causes that comes off of extraordinary circumstances lower nut effectively.
For the locking effect of more firm self lock nut, the preferred technical scheme of the utility model is that described nylon cushion is the nylon ring 5 that arranges along the nut inner wall circumference.Described nylon ring 5 preferably is arranged on an end of adjacent openings pin 2 on the nut inner wall.
The urgent moment of this locking mechanism axle drive shaft self lock nut is 300N.m ± 10N.m, after nut is urgent, refills and mixes spring cotter, and concrete test data is as shown in table 1 below:
Table 1
Data from table 1 can be found out, the locking mechanism of the self lock nut that this is novel, when adding airtight dose, it has less urgent moment, and waits in foam stability repeatedly a few hours, can be as the structure of bullet pad+fluted nut+spring cotter, the decline of oil return moment of torsion, but slightly increase, know fatigue damage, as seen the locking mechanism of this novel self lock nut need not larger urgent moment, just can have better locking effect.
To sum up, locking mechanism of the present invention be a kind of locking effect good, with locking functions and superior structural easy to assembly.
The utility model is by preferred embodiment having carried out detailed explanation.Yet, by to the studying carefully of preamble, for one of ordinary skill in the art, also be apparent concerning the variation of each embodiment.All these variations that are intended that of applicant have all dropped in the protection domain of the utility model claim.
Similar numbering refers to similar element in the whole text.For the purpose of clear, the situation that some line, layer, element, parts or feature are amplified may be arranged in the accompanying drawings.
Term used herein is only for to be illustrated specific embodiment, and it is not to be intended to the utility model is limited.Unless otherwise defined, all terms used herein (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.Also must be clear and definite be, except clear and definite definition is arranged in this article, such as in the dictionary usually the term of definition should be interpreted as in the linguistic context of this specification sheets and correlation technique, can having the consistent meaning, and the idealized or undue formalization that should not explain.Known function or structure are in briefly and clearly consider or repeat no more.
