Abstract
The utility model relates to a wheel bolt with a double locking function. A scrap edge is arranged on the head portion of the wheel bolt, the scrap edge is matched with a boss of a wheel hub, knurling teeth grooves are arranged on the outer periphery of a polish rod portion of the wheel bolt, the quantity of the knurling teeth groove is 36-45, and the strength of the wheel bolt is higher than the hardness of the wheel hub. The scrap edge is arranged on the head portion of the wheel bolt and the scrap edge is matched with the boss of the wheel hub to avoid torsional rotation of the wheel bolt during the wheel bolt is screwed, simultaneously the knurling teeth grooves are arranged on the polish rod portion of the wheel bolt, the external diameter of the teeth grooves is in interference fit with a hub bolt hole, grooves are extruded out in the hub bolt hole after installation, and the wheel bolt are prevented from sliding and rotating. Simultaneously, the teeth grooves are convenient to locate, press and install, and the scrap edge on the head portion of the wheel bolt and the teeth grooves on the polish rod portion of the wheel bolt have the double locking effect to enable the wheel bolt to be firm and reliable.
Description
Technical field:
The utility model belongs to automotive wheel tightening technology field, is specifically related to a kind of wheel bolt that has dual locking functions.
Background technique:
Along with the fast development that highway in China is built, the running velocity of vehicle is increasingly high, and is more and more harsher for Security, the reliability requirement of vehicle operating, requires the bolt of fastening wheel must have fastening reliable, effective locking function.
The anti-loose structure that present domestic wheel bolt adopts has following two kinds usually: bolt shank path portion annular knurl is locking; Bolt head is cut edge locking.For bolt shank footpath annular knurl anti-loose structure: several times behind the tire, cause that wheel hub and tire bolt matching loose trackslip in dismounting easily, tire bolt can not be effectively fastening.Cut edge locking for bolt head: if bolt light rod and wheel bore fit tolerance magnitude of interference are excessive, can cause to press-fit difficulty, also can cause the hub installing hole periphery hidden danger of quality of microscopic crack to occur; If bolt light rod and wheel bore fit tolerance magnitude of interference are too small, cause equally easily that wheel hub and tire bolt are loosening to trackslip, can not effectively fastening phenomenon.Therefore, more than locking all unreliable, occur indivedual bolt loosenesses often even come off, cause the situation that wheel throws away sometimes, brought great potential risk to vehicle operating.
The model utility content:
In sum, in order to overcome the deficiency of existing technology problem, the utility model provides a kind of wheel bolt that has dual locking functions; It is that head with wheel bolt is provided with side cut, and cutting edge cooperates with the wheel hub boss, when preventing to tighten wheel nut; Wheel bolt is reversed moving, and the polished rod with the wheel bolt middle part partly is provided with the annular knurl teeth groove, teeth groove outside dimension and hub stud holes interference fit simultaneously; The back is installed in hub stud holes, squeezes out groove, prevent that wheel bolt from trackslipping; Teeth groove also is convenient to locate and is press-fited simultaneously.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of wheel bolt that has dual locking functions, wherein: the head of wheel bolt is provided with side cut, and this side cut matches with the hub for vehicle wheel boss, and the excircle of the polished rod part of wheel bolt is provided with the annular knurl teeth groove.
Further, the intensity of described wheel bolt is higher than the hardness of hub for vehicle wheel.
Further, the quantity of described annular knurl teeth groove is 36~45.
The beneficial effect of the utility model is:
1, the utility model is that head with wheel bolt is provided with side cut; Cutting edge cooperates with the wheel hub boss, and when preventing to tighten wheel nut, wheel bolt is reversed moving; Polished rod with the wheel bolt middle part partly is provided with the annular knurl teeth groove simultaneously; Teeth groove outside dimension and hub stud holes interference fit are installed the back and in hub stud holes, are squeezed out groove, prevent that wheel bolt from trackslipping; Teeth groove also is convenient to locate and is press-fited simultaneously, and the teeth groove of the side cut of wheel bolt head and wheel bolt polished rod portion constitutes dual anti-loosing effect, makes wheel bolt fastening reliable.
2, the utility model is simple in structure, easy to use, goes for the vehicle bridge of all size, also goes in the fastening piece of similar structure simultaneously, and using scope is wide.
3, the circumferential annular knurl teeth groove of the utility model wheel bolt middle part polished rod part, it is good to have guidance quality, is easy to press-fit.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 looks schematic representation for the left side of the utility model Fig. 1;
Fig. 3 is the structural representation of the utility model when on hub for vehicle wheel, assembling.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, shown in Figure 2; A kind of wheel bolt that has dual locking functions; The head of wheel bolt 1 is provided with cuts edge 3, and this side cut 3 matches with hub for vehicle wheel 4 boss, and the excircle of the polished rod part of wheel bolt 1 is provided with annular knurl teeth groove 2; The quantity of annular knurl teeth groove 2 is 36~45, and the intensity of wheel bolt 1 is higher than the hardness of hub for vehicle wheel 4.
As shown in Figure 3, the utility model is fitted in the hub for vehicle wheel 4, through wheel nut 5, two rim for automobile wheel 6 is tightened together.
When vehicle maintenance or maintenance removing vehicle tyres wheel rim 6, need loosening or fastening wheel nut 5, at this moment, act on the warping force on the wheel nut 5, through the friction between screw pair, can be delivered on the wheel bolt 1, make wheel bolt 1 that rotation trend arranged.The annular knurl teeth groove 2 at wheel bolt 1 polished rod position will overcome this warping force and stop rotation.If the moment of torsion that acts on the wheel nut 5 is excessive, annular knurl teeth groove 2 will produce micro-rotational deformation, and at this moment, the side cut 3 of wheel bolt 1 head is blocked by the boss of wheel hub, and will produce a reverse resistance this moment, stop the rotation trend of wheel bolt 1.Like this, no matter rim for automobile wheel 6 is installed and removed how many times, and wheel bolt 1 will be effectively locking all, can not trackslip, and strengthen the Security of wheel operation.
Be noted that; The foregoing description is to the explanation of the utility model technological scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to existing technology; As long as do not exceed the thinking and the scope of the utility model technological scheme, all should be included within the desired interest field of the utility model.
