Abstract
The utility model discloses a radical location rear wheel nut, it includes nut body and location boss, and the location boss is fixed at the nut originally internally, and the one end thickness of nut body is greater than the other end thickness of nut body, and the location boss has the internal thread, fixes a position the boss part and inlays in a bolt hole of a steel ring, and the location boss has an arch, arch and steel ring joint, the bolt stem of an internal thread and a bolt fixes, and bolt stem passes the location boss. The utility model discloses it is accurate to enable steel ring circumference orientation, makes and remains normal clearance between bolt hole and bolt stem throughout to eliminate when frictional force is not enough when between steel ring and wheel hub the steel ring to the directly extrusion of bolt, in order avoiding bolt improper damage, thereby improve the life of bolt and steel ring, ensure vehicle operation safety.
Description
Technical field
The utility model relates to a kind of nut, particularly relates to a kind of radial location trailing wheel nut.
Background technique
In the prior art, the design that automotive wheel generally adopts steel ring to be separated with wheel hub, for ensureing the stationarity of wheel in High Rotation Speed, the steel ring center of support tire must be concentric with hub centre; Steel ring and wheel hub are assembled in the structure adopting hub centre to locate, 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, thus ensure that steel ring and wheel hub to remain concentric and can not movement mutually.But, this kind of centering mode can not limit steel ring to wheel hub diameter to movement, in order to prevent the two in radial direction generation relative movement, must rely on by nut to the surface friction drag of bolt suitably between fastening formed wheel hub and steel ring end plane, and never can rely on the rigid stop of bolt.That is, in 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 affecting by the producer of domestic quite some manufactured partses; low or some technology of accuracy of manufacturing can not meet artificer requirement (as steel ring, hub stud holes center circle diameter error, in distribution error etc. circumferentially); and the factors such as convenient installed by wheel; bolt hole on steel ring usually can 5 millimeter large compared with the maximum diameter of bolt; this just makes along the circumferential direction rotating relative to wheel hub of steel ring become possibility; also become when installing wheel, there is the possibility of bolt hole wall near bolt shank of steel ring.Now, once surface friction drag is not enough between steel ring and wheel hub, bolt directly will bear the extruding force that steel ring transmits by vehicle movement and impaired, may be that bolt fractures, so that there is great security incident time serious.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of radial location trailing wheel nut, it can make the accurate positioning of steel ring circumferencial direction, make to remain normal clearance between bolt hole and bolt shank, when with elimination, when between steel ring and wheel hub, frictional force is not enough, steel ring is to the direct extruding of bolt, to avoid the improper damage of bolt, thus improve the working life of bolt and steel ring, support vehicles security of operation.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of radial location trailing wheel nut, it is characterized in that, it comprises nut body and positioning boss, positioning boss is fixed in nut body, one end thickness of nut body is greater than the other end thickness of nut body, positioning boss has internal thread, positioning boss part inlay is in a bolt hole of a steel ring, positioning boss has a projection, projection and steel ring clamping, the bolt shank of internal thread and a bolt is fixed, and bolt shank is through positioning boss.
Preferably, described bolt has a hexagonal bolt head.
Positive progressive effect of the present utility model is: the utility model keeps steel ring bolt hole to locate between two parties at circumferencial direction for bolt, the bolt hole of steel ring is avoided to contact with bolt shank, prevent bolt from surprisingly fractureing and damage and ensure vehicle use safety, steel ring circumferencial direction can be overcome and locate inaccurate defect, make to remain normal clearance between steel ring bolt hole and bolt cadre, when with elimination, when between steel ring and wheel hub, frictional force is not enough, steel ring is to the direct extruding of bolt, to avoid the improper damage of bolt, thus improve the working life of bolt and steel ring, support vehicles security of operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model radial location trailing wheel nut.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model radial location trailing wheel nut comprises nut body 1 and positioning boss 2, positioning boss 2 is fixed in nut body 1, one end thickness of nut body 1 is greater than the other end thickness of nut body 1, positioning boss 2 has internal thread 22, positioning boss 2 part inlay is in a bolt hole 31 of a steel ring 3, positioning boss 2 has a projection 21, projection 21 and steel ring 3 clamping, the bolt shank 41 of internal thread 22 and a bolt 4 is fixed, and bolt shank 41 is through positioning boss 2.Bolt 4 has a hexagonal bolt head 42, convenient like this installation.The length of nut body is ten millimeters, and the length of positioning boss is 15 millimeters, and such intensity is best.Protruding 21 can improve fixed effect with steel ring 3 clamping.
The utility model radial location trailing wheel nut is by being arranged on the positioning boss part inlay of nut body side in the bolt hole of steel ring, the projection of positioning boss and steel ring clamping, bolt shank directly passes positioning boss and fixes thus fixing bolt with the internal thread on positioning boss, define the perpendicularity of steel ring radial position and bolt, steel ring bolt hole is kept to locate between two parties at circumferencial direction for bolt, bolt can be ensured, nut and steel ring bolt hole are coaxially arranged, strengthen the fixing of bolts and nuts, decrease the loose or dislocation phenomenon of vehicle at driving process, avoid steel ring and boss bolt directly to contact and make it be out of shape with steel ring extruding bolt or fracture, bolt working life and vehicle safety can be improved.In addition, steel ring is accurate in circumferential locations, make the normal clearance remained between steel ring bolt hole and bolt shank, can to eliminate when between steel ring and wheel hub frictional force not enough time steel ring to the direct extruding of bolt, avoid the improper damage of bolt, thus improve the working life of bolt and steel ring, support vehicles security of operation.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
