Abstract
The utility model discloses a reinforced radial positioning combined double-pad movable screw nut gasket assembly, which comprises a screw nut, a connecting gasket and a regulating gasket in coaxial arrangement, wherein the connecting gasket is positioned between the screw nut and the regulating gasket, the end surface in contact with a steel ring and the regulating gasket are coaxial, and the regulating gasket is provided with a lug boss matched with a screw bolt hole of the steel ring. The reinforced radial positioning combined double-pad movable screw nut gasket assembly has the advantages that the steel ring positioning in the circumferential direction can be accurate, so the normal gap is always maintained between the screw bolt hole of the steel ring and the screw bolt rod part, the perpendicularity among the screw bolt, the steel ring and a wheel hub is always maintained for eliminating the direct extrusion of the steel ring on the screw bolt when the friction force between the steel ring and the wheel hub is insufficient, and the abnormal damage of the screw bolt is avoided, so the service life of the screw bolt and the service life of the steel ring are prolonged, and the operation safety of vehicles is ensured.
Description
Technical field
The utility model relates to a kind of nut gasket component, particularly relates to the two pad of a kind of reinforced radial location combined type traveling nut gasket assembly.
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 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 the two pad of a kind of reinforced radial location combined type traveling nut gasket assembly, it can make the accurate positioning of steel ring circumferencial direction, make to remain normal clearance between steel ring bolt hole and bolt shank, remain the perpendicularity of bolt and steel ring and wheel hub, 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: the two pad of a kind of reinforced radial location combined type traveling nut gasket assembly, it is characterized in that, it comprises nut, connection packing ring, the adjusting washer (disk) of coaxial setting, connect packing ring between nut and adjusting washer (disk), end face that adjusting washer (disk) contacts with a steel ring is coaxial and be provided with the boss with steel ring bolt hole adaptation.
Preferably, described boss is shaped as taper shape.
Preferably, described nut is provided with a hexagonal phase incisal bevel, and the angle of hexagonal phase incisal bevel is 50 degree.
Preferably, described nut is provided with a first parallel counterface, connects packing ring and is provided with a second parallel counterface.
Preferably, between described nut and connection packing ring, be provided with first gap, connect between packing ring and adjusting washer (disk) and be provided with second gap.
Preferably, described adjusting washer (disk) is provided with a bolt hole.
Positive progressive effect of the present utility model is: the utility model can make the accurate positioning of steel ring circumferencial direction, make to remain normal clearance between steel ring bolt hole and bolt shank, remain the perpendicularity of bolt and steel ring and wheel hub, 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.

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 6, the two pad of the reinforced radial location combined type of the utility model traveling nut gasket assembly comprises nut 3, connection packing ring 7, the adjusting washer (disk) 14 of coaxial setting, connect packing ring 7 between nut 3 and adjusting washer (disk) 14, end face that adjusting washer (disk) 14 contacts with a steel ring is coaxial and be provided with the boss 16 with steel ring bolt hole adaptation.Boss 16 be shaped as taper shape.
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.
Adjusting washer (disk) 14 is provided with a bolt hole 19, and the diameter of bolt hole 19 is than the large 0.5mm of the diameter of bolt, and bolt hole 19 is for the perpendicularity of fixing bolt position and adjustment bolt.When nut lockk bolt generation bolt and steel ring end face non-perpendicularity are greater than 0.5mm, by adjusting washer (disk), can automatically adjust the perpendicularity of bolt, thereby avoided the bolt hole on bolt and steel ring directly to come in contact, thereby guaranteed that the phenomenon of damage and direct friction does not occur the bolt hole on steel ring.Two gasket thickness are up to 22mm in addition, therefore the bolt hole on adjusting washer (disk) has directly contacted 22mm with bolt shank, by this segment distance, can effectively adjust the perpendicularity of bolt, guarantee that as much as possible bolt partial surface rubs, reduced widely bolt and damage has occurred or split off because off plumb state is installed.Without cease to vertical situation when the relative steel ring end face of bolt shank, effectively to have aligned the perpendicularity of bolt and steel ring, thereby guaranteed that bolt does not bend and damages the in the situation that of nut check, assurance bolt thread and nut thread are joined full the optimum state.
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.
