Description

Technical Field

[0001] The utility model relates to the technical field of ABS tooth rings, in particular to a dust-proof ABS tooth ring. Background Art

[0002] The ABS tooth ring is a key component in the anti-lock braking system (ABS) of an automobile. It is usually installed on the wheel hub or the transmission shaft of the wheel and consists of a series of evenly distributed teeth. Its main function is to provide information on the wheel speed for the ABS system. During vehicle driving, as the wheel rotates, the teeth of the tooth ring continuously pass by the sensors installed nearby, thereby generating pulse signals. The control unit of the ABS system accurately calculates the wheel speed based on the frequency and changes of these pulse signals. The ABS tooth rings of different vehicle models may vary in size, number of teeth, and material. Common materials include steel or cast iron, etc., to ensure sufficient strength and wear resistance. In some high-performance vehicles, more advanced lightweight and high-strength materials may be used to manufacture the ABS tooth ring to reduce weight and improve response speed.

[0003] The prior art such as the utility model with the publication number CN204821524U. The utility model relates to an automobile ABS tooth ring, including a tooth ring body. An induction hole is opened on the tooth ring body. The induction hole is opened from one side of the tooth ring body and is a blind hole. An induction body is filled in the induction hole. By the interaction between the induction body and the induction probe, the wheel speed is measured, and the reaction is sensitive and accurate. An installation ring is arranged inside the tooth ring body, and installation holes are arranged on the installation ring. The induction body is adhesively bonded in the induction hole by glue. The induction hole is a square hole. A 0.2 - 0.4 mm galvanized layer is plated on the outer layer of the tooth ring body and the installation ring. After galvanizing, the tooth ring has better corrosion resistance and is durable. Compared with the existing technology, the utility model provides an automobile ABS tooth ring. The structure of the utility model is simple, the production is simple, and it is easy to process, ensuring that the ABS system of the vehicle is sensitive in induction and improving driving safety. It solves the problems that the ABS tooth rings of the front and rear brakes of current automobiles are generally made of iron products, and their teeth are manufactured by mechanical processing. Since the traditional iron product processing procedures are numerous and the efficiency is low, especially the processing of the tooth ring is difficult and requires special manufacturing equipment, which is very cumbersome; and more and more manufacturers use powder metallurgy methods to manufacture, but the powder metallurgy parts are porous materials with poor density, making the powder metallurgy parts do not have the performance and stability of iron products.

[0004] In daily work, it is found that during the use of the ABS gear ring, its surface is prone to being contaminated with a large amount of impurities and dust. The dust is likely to accumulate in the tooth grooves of the ABS gear ring. After excessive accumulation of dust and impurities, it is difficult to clean thoroughly later, which hinders the accurate detection of the rotation signal of the gear ring by the sensor, resulting in the situation that the sensor generates incorrect or unstable pulse signals, and further leading to the problems of poor dust-proof effect of the existing ABS gear ring and troublesome subsequent cleaning. Summary of the Invention

A plurality of equally spaced teeth are arranged on the surface of the gear ring body. The protection device is arranged on the surface of the teeth. The protection device includes a convex ring and a transparent protection plate. The convex ring is fixedly connected to the surface of the gear ring body. The transparent protection plate is arranged on one side of the convex ring. An outer ring is fixedly connected to the outer surface of the gear ring body. An insertion ring is fixedly connected to the surface of the transparent protection plate close to the convex ring. A slot is opened on the surface of the convex ring. The insertion ring is inserted into the inner wall of the slot. A connection component is arranged on the inner wall of the convex ring. A plug is fixedly connected to the side of the transparent protection plate close to the outer ring. The plug is inserted into the inner wall of the outer ring. Through the above components, the insertion ring and the plug on the surface of the transparent protection plate are respectively inserted into the slot on the surface of the convex ring and the inner wall of the outer ring, and then connected through the connection component, so as to prevent dust, reduce the direct attachment of dust on the gear ring body, resulting in difficult subsequent cleaning and unclean cleaning affecting normal use.

[0007] Preferably, the transparent protection plate is made of plexiglass material. Through the above components, the transparent protection plate made of plexiglass material has good transparency, is not easy to break, and has strong impact resistance.

Four positioning holes are opened on the surface of the convex ring. The positioning rods are inserted into the inner walls of the positioning holes on the surface of the convex ring. Through the above components, when installing the transparent protection plate, the positioning rods can be aligned with the positioning holes on the surface of the convex ring, so as to play a role in positioning the transparent protection plate during installation.

[0009] Preferably, the connecting component includes a plug post which is slidably connected to the inner wall of the convex ring, and is inserted into the inner wall of the inserting ring. A movable rod is rotatably connected to the surface of the plug post, and a threaded groove is arranged on the surface of the movable rod, which is threadedly connected to the inner wall of the convex ring. One end of the movable rod is fixedly connected with a control head. Through the above components, after the transparent protection plate is placed, the movable rod can drive a part of the plug post to be inserted into the inner wall of the inserting ring, and then rotate the movable rod. After the threaded groove of the movable rod cooperates with the convex ring, the plug post can be driven to move continuously until the plug post is completely inserted, thus completing the connection.

[0010] Preferably, a groove is formed on the surface of the convex ring close to the control head, and the control head is arranged in the groove. Through the above components, the groove in the convex ring can allow the control head to enter, playing a role of hiding.

[0011] Preferably, a spring is sleeved on the surface of the movable rod, and both ends of the spring are fixedly connected to the plug post and the inner wall of the convex ring respectively. Through the above components, when the threaded groove of the movable rod loses connection, the spring can drive the plug post to reset, pulling the plug post out of the inserting ring, thus completing the use.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] In the present utility model, by setting the auxiliary device, dust prevention and shielding can be carried out on the ABS tooth ring, reducing the adhesion of impurities and dust on the ABS tooth ring, which may cause the impurities to be difficult to clean after long-term adhesion, thus affecting the accurate detection of the rotation signal of the ABS tooth ring by the sensor.
