Description
Technical field
The present invention relates to automobile steering system field, more particularly to a kind of sealing collar for automobile steering system.
Background technology
The effect of automobile steering system is to ensure that automobile adapts to road and changes travel direction in the process of moving, or is kept
Stable straight-line travelling.When driver turn steering wheel, by steering spindle, steering universal joint and transmission shaft, torque will be turned to
Input steering gear.A series of this parts is known as steering control mechanism from steering wheel to transmission shaft.Pitman arm, turn to main drawing
Bar, knuckle arm, left/right tie rod arm, track rod are collectively referred to as steering gear.On steering gear, such as surely
Fixed pole, on track rod, has bulb component.Bulb component is a very important parts, it is just as the knee of human body
Lid is the same, provides a strong fulcrum for chassis steering system, plays a supportive role, while different using ball-type connection realization
The power transmission of axis, there is provided the rotation of multi-angle so that steering mechanism is able to smooth-going and turns to, and reduces vibrations and realizes that smooth-going turns
To.Bulb component is made of parts such as bulb, card slot, rubber sleeve and collars, there is lubricating grease in card slot, is reduced and is rubbed for ball joint-rotating
Wipe and use.Meanwhile lubricating grease is dried in order to prevent, and vehicle cause to be mixed into dirt etc. in card slot in the process of moving it is different
Thing, causes bulb stuck, can not rotate, it is necessary to fix a dust protection rubber circle on bulb component, and fix the tight of the rubber ring
It is fixedly mounted with that to put be exactly collar.
Collar can ideally fasten dust protection rubber circle, be one of the precondition of bulb component efficient stable work.If
Collar can not function well as sealing function, then can seriously affect the service life of bulb component, and then influence automobile chassis steering system
The performance of system effect.Working environment and functional requirement based on more than, it is desirable to which collar cannot injure matched rubber parts, together
When there is suitable clamping force.Collar on the market is primarily present following shortcoming at present：In work condition state, collar is to dust-proof rubber
The clamping force deficiency of gum cover, clamping force is uneven, can also injure rubber parts.
Therefore, those skilled in the art is directed to developing a kind of clamping force uniformly and is not easy to injure the collar of rubber parts.
The content of the invention
In view of the drawbacks described above of the prior art, it is equal that the technical problems to be solved by the invention are to provide a kind of tensile force
It is even, and collar neither inwardly scratches tight collar, cuts bad rubber parts, and it is not outstanding too many, the sealing collar of peripheral component is influenced,
So as to reduce the frequency for producing quality problems, the service life of bulb product is improved.
To achieve the above object, the present invention provides a kind of sealing collar for automobile steering system, the collar to exist
It is ellipse when not extending, the oval major axis dimension and minor axis dimension are adjustable, and the collar is along its width
Coiling, the collar includes the first tail end and the second tail end, and when not extending, first tail end and second tail end are set
Into overlapped in the direction of the width, lap position and the endpoint formation window of the oval major axis, with using along steel wire
The collar that thickness direction carries out coiling formation is compared, and winding method in the width direction can produce the clamping force of bigger.
Further, window size of the collar when not extending adjusts, by different window sizes is set come
Collar is controlled in clamping force caused by different operating modes.
Further, the collar is substantially circular in extension, and the collar is in extension, first tail end and institute
The second tail end is stated to be generally aligned in the same plane with the collar center of circle, the collar and rubber ring snap-fit, ensure under operating mode
Collar, which is in, compares perfectly round, so that uniform in the all-round tensile force in the range of.
Further, the window size according to collar during extension needs that the power that rubber ring applies is adjusted.
Further, the tail end of the collar is smooth arc-shaped, by the mould of special designing, during coiling
Collar is thrust, and is produced smooth arc-shaped collar tail end, is avoided scuffing of the collar tail end to rubber parts under operating mode.
Further, when the collar extends, when the collar extends, the first tail end and the second tail of the collar
The distance that the internal diameter tangent line at end is projected with it on rubber ring respectively is that X1 and the value of X2, X1 and X2 are all higher than zero, therefore collar
Tail end will not inwardly scratch tight collar, cut bad rubber parts.
Further, when the collar extends, distance is between the first tail end of the collar and the second tail end vertex
The value of Y, Y are more than zero diameter for being less than the collar, make the tail end of collar outwards excessively not prominent, influence peripheral component.
Preferably, the collar is made of naturally molding flat wire, the collar with carrying out coiling formation using round steel wire
Compared to the clamping force that can produce bigger.
Further, the edge of the collar is smooth arc-shaped, and the smooth edge of collar will not cut bad rubber parts.
Further, the thickness for the flat wire that the collar uses is more than its width.
Compared with prior art, the technique effect of the invention is as follows：
1st, the problem of clamping force is insufficient under work condition state for collar, when designing collar, considers the operating mode of collar, makes
The collar for obtaining the condition of delivery and work condition state contrasts, and sufficiently large deformation quantity can be produced, so as to produce sufficiently large clamping force；Together
When, collar is made using flat wire, the coiling that collar is carried out along width is molded.
2nd, for collar under work condition state clamping force problem of non-uniform, when designing collar, consider the operating mode of collar, hand over
When goods state collar is unexpanded, to be oval, but collar is then in circle when working status is expanded.
3rd, the problem of rubber parts is injured under work condition state for collar：Collar tail end is made smooth arc-shaped, and adopt
Collar is produced with the band steel of the smooth of the edge rounded corner；By design, ensure collar under work condition state, tail end inwardly do not scratch into,
Cut rubber sleeve.
In conclusion the present invention ensures that collar is under operating mode by taking into full account operating mode in production process is designed
Compare perfectly round, so that uniform in the all-round tensile force in the range of；Meanwhile at the arc-shaped tail end for passing through specially treated
In appropriate location, tight collar is neither inwardly scratched, cuts bad rubber parts, but it is not outstanding too many, peripheral component is influenced, reduces production
The frequency of raw quality problems, improves the service life of bulb product.
It is described further below with reference to the technique effect of design of the attached drawing to the present invention, concrete structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
