Description
Technical Field
The utility model relates to the technical field of bolts, in particular to a wheel bolt with a tooth structure.
Background
At present, the wheel connection on the automobile is commonly adopted by two structures of a hub bolt, a wheel nut and a wheel bolt, wherein the wheel bolt is of an integrated type and a combined type. Compared with the integrated wheel bolt, the combined wheel bolt can provide larger clamping force under the same torque due to smaller friction diameter, and has smaller friction loss and more repeated use times. However, in the combined wheel bolt, the washer is easy to fall off, which brings inconvenience to the use of the wheel bolt.
Disclosure of Invention
The utility model provides a wheel bolt with a tooth structure, which aims to overcome the defects of the prior art.
In order to achieve the above purpose, a wheel bolt with a tooth structure is designed, which comprises a bolt head, a straight rod part and a threaded rod part, and is characterized in that: the outer edge of the straight rod part is provided with a circle of anti-skid teeth, a gasket is sleeved outside the straight rod part between the head of the bolt and the anti-skid teeth, and one side of the gasket, which is close to the anti-skid teeth, is provided with a step.
The inner diameter of the step is larger than the outer diameter of the straight rod part, and the inner diameter of the step is smaller than the outer diameter of the anti-skid tooth.
One end of the gasket, which is close to the anti-slip teeth, is provided with an inclined surface structure, and a step is formed after the inclined surface structure is stamped.
The inner diameter of the inclined surface structure is larger than that of the gasket, and the inclined surface structure and the conical surface of the gasket form an obtuse angle.
And a pit is arranged on one side of the head of the bolt.
The external diameter of the anti-slip teeth is 13.7+/-0.1 mm, and the length of the anti-slip teeth is 2+/-0.5 mm.
The anti-skid teeth and the straight rod part are of an integrated structure.
Compared with the prior art, the anti-slip tooth structure is added on the straight rod part of the wheel bolt to prevent the gasket from falling off, the tooth-shaped structure is small in size, the force required by deformation is smaller, the forming is easier, and the service life of the die is longer.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 5, a circle of anti-slip teeth 4 are arranged on the outer edge of the straight rod part 2, a gasket 5 is sleeved on the outer side of the straight rod part 2 between the bolt head part 1 and the anti-slip teeth 4, and a step 6 is arranged on one side, close to the anti-slip teeth 4, of the gasket 5.
The inner diameter of the step 6 is larger than the outer diameter of the straight rod part 2, and the inner diameter of the step 6 is smaller than the outer diameter of the anti-skid teeth 4. Thereby ensuring that the washer 5 can rotate freely without falling off.
According to the utility model, one end of the washer 5, which is close to the anti-slip tooth 4, is provided with an inclined surface structure 8, and the inclined surface structure 8 is stamped to form a step 6. The inner diameter of the inclined surface structure 8 is larger than that of the gasket 5, and the inclined surface structure 8 and the conical surface of the gasket 5 form an obtuse angle. The ramp structure 8 deforms after stamping to form the step 6.
One side of the bolt head 1 is provided with a pit 7, which plays a role in weight reduction.
The external diameter of the anti-slip teeth 4 is 13.7 plus or minus 0.1mm, and the length of the anti-slip teeth 4 is 2 plus or minus 0.5mm.
The anti-skid teeth 4 and the straight rod part 2 are of an integrated structure.
In the assembly of the bolts of the present utility model, as shown in fig. 6, after the wheel bolts 9 pass through the inner holes of the hub 11 and the brake disc 10, the heads of the wheel bolts 9 are screwed into the inner threaded holes of the hub bearing 12 by applying torque, and the wheel bolts 9 are attached to the hub 11 to generate clamping force, so that the hub 11 and the brake disc 10 are clamped on the hub bearing 12 to play a role in connecting the wheels and the chassis.
When specifically using, if there is not anti-slip tooth 4, packing ring 5 can drop the threaded rod portion, probably in screw thread ending department clamping stagnation, can't laminate with the holding surface during the assembly, influences assembly efficiency. And the anti-skid teeth 4 of the tooth-shaped structure have small volume, smaller force required by deformation, easier molding and longer service life of the die.
