Description
Technical Field
The utility model belongs to the technical field of automobile wheel hub bolt and specifically relates to a locking dustproof wheel hub bolt is related to.
Background
A hub bolt is used for locking a steel ring, a wheel center and a brake hub into a whole in an automobile. The bolt consists of a head part and a bolt part, wherein a cylindrical section with external threads in the bolt is called a threaded section, a cylindrical section without the external threads in the bolt is called a rod section, and a nut is in threaded connection with the threaded section.
When a heavy-duty automobile is used, the hub bolt bears very large pressure constantly, and the automobile jolts seriously especially under the conditions of overload or poor road conditions. The steel ring, the wheel center and the brake hub are stressed greatly, relative swinging can be generated between the steel ring and the bolt, extrusion is generated between the steel ring and the nut, the bolt can be easily broken, the nut is loosened, and the service life of the hub bolt is shortened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide a locking dustproof wheel hub bolt.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides a locking dustproof wheel hub bolt, includes bolt, nut, shield, first gasket and second gasket, the rear end screw-thread fit of nut and bolt, the screw department of nut rear end is located to the shield, shield and nut screw-thread fit, the rotatable riveting of first gasket is in the front end of nut, second gasket movable sleeve is established in the bolt outside, the place ahead of first gasket is located to the second gasket, the front end of first gasket is equipped with the toper arch that the round surrounded the bolt, the rear end of second gasket is equipped with round tapered groove in the protruding position that corresponds of toper, through increasing first gasket, second gasket for the contact surface increases, and the interaction power increases, and the fastness strengthens.
Preferably, the front end of the nut is provided with a convex ring, the rear end of the first gasket is provided with a concave ring matched with the convex ring, and the convex ring is embedded into the concave ring, so that the first gasket and the nut can be rotationally riveted into a whole.
Preferably, the second gasket is dodecagonal and is convenient to detach.
Preferably, the rear end of shield is equipped with the sphere arch, the bellied edge of sphere is equipped with a plurality of and caves in for it is easier that the finger snatchs the sphere arch.
Preferably, the bolt includes shank of bolt and locates the bolt head of shank of bolt front end, the shank of bolt is equipped with two rings of spaced straight line knurls in the position that is close to the bolt head for the bolt is fastened more with wheel hub's mounting hole cooperation, two rings be equipped with dustproof annular between the straight line knurl for hold dust and piece, the card is dead when preventing the bolt dismouting.
Preferably, the side of the bolt head is provided with an arc-shaped surface used for being matched with the hub, so that the bolt can be prevented from rotating during dismounting.
Through adopting foretell technical scheme, the beneficial effects of the utility model are that: the utility model discloses an increased first gasket, second gasket between nut and bolt head for wheel hub increases to the contact surface between the nut, and the interaction force between contact surface and the contact surface increases, thereby has increased the fastness of being connected between wheel hub bolt and the wheel hub. The utility model discloses still set up arch and recess respectively at first gasket, second gasket, produce vibrations when the vehicle, the second gasket produces not hard up with the bolt, along with not hard up increase for the interlock of two gaskets is inseparabler, because first gasket is as an organic whole with the nut riveting, so inseparabler between second gasket and the nut, has increased the fastness of being connected between wheel hub bolt and the wheel hub. The utility model discloses simple structure, it is firmly inseparable, easy dismounting.
