Description

Locking dustproof wheel hub bolt convenient to detect

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 convenient to detect 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 very large in stress, 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, and the nut is loosened.

In the driving process of an automobile, the automobile is influenced by factors of different geographical environments, water, acid and the like can be adhered to the bolt and the nut, and liquid, dust and sand grains which corrode and corrode the bolt and the nut are corroded and corroded, so that the nut is loosened and falls off.

Therefore, before the automobile runs, a driver can check each hub bolt, an alarm is given in advance, and the automobile is prevented from getting ill, so that the running safety of the automobile is guaranteed. However, the driver can only check the vehicle by means of a tool, and the operation is difficult, time-consuming and labor-consuming.

Preferably, the first gasket and the nut are riveted into a whole.

Preferably, the second gasket is dodecagonal and is convenient to detach.

Preferably, the orientation indicating means is an arrow.

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:

1. the utility model discloses a set up the dustproof cap that has dustproof function and have directional indicating device, after wheel hub bolt nut screws, will prevent that the dustproof cap extrudees the chucking hard and covers the nut, and directional indicating device on the dustproof cap is towards same direction, and whether the driver of being convenient for can be direct judge and detect bolt nut not hard up from the vision, easy operation, labour saving and time saving ensures vehicle operation and life safety to maintain automobile wheel hub safety and performance effectively.

2. The utility model discloses an increased locking device (first gasket, second gasket promptly) between nut and bolt head for wheel hub increases to the contact surface between the nut, and the interact power increase between contact surface and the contact surface, thereby has increased the fastness of being connected between wheel hub bolt and the wheel hub.

3. 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.
