Description
Technical field
The utility model relates to automotive axle technical field, specifically a kind of disk spring structural joint assembly.
Background technique
As market is higher and higher to operation comfort type and steering return requirement, to meet customer need, we are new
It does a lot of work in terms of product, new technology.It originally uses in the market more for forth generation bulb: upper and lower steel ball seat bullet
Spring connector assembly, advantage: in use when ball pin, ball seat mild wear, reliable spring adjusts to be automatically replenished displacement, prolongs
Lengthening joint assembly service life.Disadvantage: axial displacement is big, is influenced by spring structure, axial tolerance 1.5 ~ 2.In vehicle stress mistake
Cheng Zhong, if lower ball base easily causes deformation by greater impact power, thus cause connector assembly axial displacement excessive, axial displacement
Stability it is impacted.
Summary of the invention
To solve the above problems, the purpose of the utility model is to provide a kind of disk spring structural joint assemblies.
To achieve the above object, a kind of disk spring structural joint assembly, including connector and bulb are inserted in and connect the utility model
The ball pin head shot in seat, ball pin can be freely rotated in ball seat, and dust cover is fixed on the bar of ball pin, and the other end of dust cover is logical
One end that dust cover retainer ring is fixed on ball seat is crossed, is fixed with the dish for being close to bulb by bottom plate in the opening of the ball seat other end
Spring is provided with split pin on the slotted nut that the end of ball pin bar screws, is provided with tubaeform open at the disk spring at connector ball seat position
Mouthful, the support end of disk spring is located in horn opening, and the horn opening side wall between disk spring and ball pin bulb is embedded
There is support ball free to rotate, support ball is multiple, and is evenly spaced in the horn opening side of disk spring support end
In wall.
Moreover, it is contemplated that it is thin to upper ball base wall, connector assembly looseness problem is easily led to after abrasion is used for a long time, our butt joints
Shell Internal Spherical Surface has carried out high-frequency therapeutic treatment, hardness HRC53 ~ 58, and 1.2 ~ 2.5mm of quench-hardened case improves connector completely instead of upper ball base
Wear-resisting property.
For the big problem of axial displacement for avoiding conventional springs structure, we devise completely new disk spring and pass through back-up roller
The support phase of pearl combines, and disk spring substitutes the effect of two parts of lower ball base and spring, and upper surface is directly contacted with bulb, and circularity is good
Torque is uniform, stability is good, and axial displacement can effectively solve the problems, such as that conventional springs structure axial displacement is big less than 0.5, and lead to
Cross the limit design of disk spring, support ball and bottom plate, it can be ensured that for connector assembly when vehicle is hit power, axial displacement is still
It can be controlled in effective range, guarantees the stability of properties of product.
Ball pin reaches Ra0.2 using bulb tumbling and whole polishing treatment, roughness, enhances connector assembly wearability,
Torque is submissiveer.
Disk spring structural joint assembly axial gap is small, and comfort is good, and connector directly assembles ball pin, refill support ball,
Riveted after disk spring and bottom plate is a kind of brand new of connector assembly, reduces components size, saves assembly time.This knot
Structure design, the complete alternative ball seat spring connector assembly of steel up and down currently on the market, assembly is simple, and axial displacement is small, together
When can solve the problems, such as main engine plants worry steering reversal, wide market.
Detailed description of the invention
The utility model is described further now in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of disk spring structural joint assembly, is inserted in the ball pin in 1 ball seat of connector including connector 1 and bulb
2, ball pin 2 can be freely rotated in ball seat, dust cover 7 is fixed on the bar of ball pin 2, dust cover 7 is by silicon rubber, fluorubber, day
Right rubber Compound Machining forms, and silicon rubber has high-low temperature resistant outstanding, resistance to ozone and anti-weather-aging property, -70~260
DEG C operating temperature range in be able to maintain that its is distinctive using elasticity and resistance to ozone, the advantages that resistance to weather；Fluorubber, which has, to be protruded
Heat-resisting (200~250 DEG C), oil resistance；Natural rubber has good comprehensive mechanical property, cold resistance, higher rebound
Property and wear-resisting, it is alkaline-resisting, anti-oxidant anti-aging by the compound high-low temperature resistant for substantially increasing dust cover 7 of a variety of rubber, oil resistant, with
And with excellent mechanical performance；The other end of dust cover 7 is fixed on one end of ball seat by dust cover retainer ring 8, and ball seat is another
The disk spring 3 for being close to bulb is fixed in the opening at end by bottom plate 4, is provided on the slotted nut 6 that the end of 2 bar of ball pin screws
Split pin 5 is provided with horn opening 9 at the disk spring 3 at 1 ball seat position of connector, and the support end of disk spring 3 is located at horn opening
In 9, and 9 side wall of horn opening between 2 bulb of disk spring 3 and ball pin is embedded with support ball 10 free to rotate, branch
It is multiple for supportting ball 10, and is evenly spaced in 9 side wall of horn opening of 3 support end of disk spring, and disk spring 3 is driven plain, i.e.,
When reaching maximum compression degree, the bulb of ball pin 2 is just in close contact with each support ball 10, realizes support ball 10 at this time
Support.
Utility model works principle: the major function of connector assembly is bridge steering before realizing, so that full-vehicle steering is driven,
Connector 1 is connect with steering linkage, and steering first passes through the knuckle arm of bridge before steering wheel drives Drag link, Drag link to drive, and is turned to
Joint arm drives knuckle, and knuckle drives drag link to be turned to, and is during which most directly exactly the steering that connector assembly is realized, ball
Pin 2 is connected with the taper hole on steering wheel plumbing arm and knuckle arm, is fastened by slotted nut 6, and split pin 5 is lockked.It is dust-proof
Cover 7 and 8 is dustproof construction, prevents silt from entering and causes to wear, is transmitted to ball pin 2 by the steering force on vehicle, ball pin 2 passes through dish
The power of shape spring 3 is swung, and is realized and is turned to.Disk spring 3 is high rigidity disk spring, limits and compresses by bottom plate 4, guarantees connector
Assembly power is stablized, it is ensured that axial displacement.
