Abstract
The utility model discloses a strengthening type radial locating combined type movable nut and gasket assembly comprising a nut and a gasket which are arranged coaxially. A boss which is in fit with a bolt hole of a steel ring is coaxially arranged at the end face, making contact with the steel ring, of the gasket. According to the strengthening type radial locating combined type movable nut and gasket assembly, the defect that the steel ring is not accurately located in the peripheral direction is overcome, a normal interval is kept between the bolt hole of the steel ring and the rod part of a bolt all the time so that direct squeezing to the bolt from the steel ring when friction force between the steel ring and a hub is not enough can be eliminated, the bolt is prevented from being damaged abnormally, and accordingly the service life of the bolt and the steel ring is prolonged, and safe operation of an automobile is ensured.
Description
Technical field
The utility model relates to a kind of traveling nut gasket assembly, particularly relates to a kind of reinforced radial location combined movable nut gasket component.
Background technique
In the prior art, automotive wheel generally adopts the steel ring design separated with wheel hub, be to guarantee the stationarity of wheel in High Rotation Speed, the steel ring center of support tire must with wheel hub centres; Steel ring and wheel hub assembling adopt in the structure of wheel hub centralized positioning, and the link of steel ring and wheel hub is the nut of bolt and fixing bolt.
In above-mentioned steel ring and wheel hub positioning connection, the positioning center hole of steel ring matches with high precision with the positioning cylinder outside diameter of wheel hub, thereby has guaranteed steel ring and wheel hub to remain concentric and can mutually not move.But, this kind of centering mode can not limit steel ring to wheel hub diameter to movement, in order to prevent that the two from radially relatively moving, must rely on by nut the suitable surface friction drag between fastening formed wheel hub and steel ring end plane of bolt, and never can rely on the rigid of bolt to stop.That is to say, under normal state, the bolt hole of steel ring should not contact to some extent with bolt shank, and therefore, bolt just can not fracture due to the extruding of steel ring bolt hole or damage distortion.
But; owing to affected by the domestic quite producer of some manufactured partses; low or some technology of accuracy of manufacturing can not meet artificer's requirement (as steel ring, hub stud holes center circle diameter error, distribution error on circumference etc.); and wheel is installed the factors such as convenient; bolt hole on steel ring conventionally can be compared with large 5 millimeter of the maximum diameter of bolt; this just makes along the circumferential direction rotating and become possibility with respect to wheel hub of steel ring; also become when installing wheel, exist the bolt hole wall of steel ring near the possibility of bolt shank.Now, once surface friction drag is not enough between steel ring and wheel hub, bolt will directly bear extruding force that steel ring transmits by vehicle movement and impaired, may be that bolt fractures, so that there is great security incident when serious.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reinforced radial location combined movable nut gasket component, it can overcome steel ring circumferencial direction and locate inaccurate defect, make to remain normal clearance between steel ring bolt hole and bolt cadre, to eliminate the direct extruding of steel ring to bolt when frictional force between steel ring and wheel hub is not enough, to avoid the improper damage of bolt, thus working life, the support vehicles security of operation of raising bolt and steel ring.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of reinforced radial location combined movable nut gasket component, it is characterized in that, it comprises the nuts and washers of coaxial setting, and the end face that described packing ring contacts with a steel ring is coaxially arranged with the boss with steel ring bolt hole adaptation.
Preferably, described boss is shaped as taper shape.
Preferably, described nut is provided with the first counterface, and packing ring is provided with the second counterface, is provided with a free gap between nuts and washers.
Preferably, described packing ring is provided with a bolt hole.
Positive progressive effect of the present utility model is: the utility model can overcome steel ring circumferencial direction and locate inaccurate defect, make to remain normal clearance between steel ring bolt hole and bolt cadre, to eliminate the direct extruding of steel ring to bolt when frictional force between steel ring and wheel hub is not enough, to avoid the improper damage of bolt, thus working life, the support vehicles security of operation of raising bolt and steel ring.
accompanying drawing explanation
Fig. 1 is the structural representation of the reinforced radial location combined movable of the utility model nut gasket component.
Fig. 2 is the structural representation of nut in the utility model.
Fig. 3 is the external structure schematic diagram of the utility model middle washer.
Fig. 4 is the internal structure schematic diagram of the utility model middle washer.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figures 1 to 4, the reinforced radial location combined movable of the utility model nut gasket component comprises nut 3 and the packing ring 7 of coaxial setting, and the end face that described packing ring contacts with a steel ring is coaxially arranged with the boss 11 with steel ring bolt hole adaptation.Boss 11 be shaped as taper shape.
The utility model can overcome steel ring circumferencial direction and locate inaccurate defect, make to remain normal clearance between steel ring bolt hole and bolt cadre, to eliminate the direct extruding of steel ring to bolt when frictional force between steel ring and wheel hub is not enough, to avoid the improper damage of bolt, thus working life, the support vehicles security of operation of raising bolt and steel ring.
The utility model can guarantee that nut, packing ring and steel ring bolt hole coaxially arrange, steel ring is accurate in circumferential locations, make the normal clearance remaining between steel ring bolt hole and bolt cadre, can eliminate the direct extruding of steel ring to bolt when frictional force between steel ring and wheel hub is not enough, avoid the improper damage of bolt, thereby improved the working life of bolt and steel ring, support vehicles security of operation.
The utility model embeds steel ring bolt hole by boss, define steel ring radial position, steel ring and hub member frictional force are reduced, having avoided steel ring and boss bolt directly to contact with steel ring extruding bolt makes its distortion or fractures, and can effectively guarantee the coaxality of nut and packing ring to be conducive to transmit positive pressure, guaranteeing has enough frictional force between steel ring and wheel hub, prevent that steel ring and wheel hub from relatively rotating, and can improve bolt working life and ride safety of automobile.
Nut 3 is provided with hexagonal phase tangent plane 6, and the angle of hexagonal phase tangent plane is 50 degree.
Nut 3 is provided with the first counterface 5, and packing ring 7 is provided with the second counterface 13, is provided with a free gap 18 between nut 3 and packing ring 7, and the utility model is by the perpendicularity of the flexible adjusting nut of packing ring and bolt like this.When bolt is with respect to steel ring counterface out of plumb or when affected by external force extruding occurs, by free gap, the position of adjusting nut and bolt effectively, the normal operation of assurance bolt.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
