The present invention relates to a car ABS wheel sensor and a method for manufacturing the same, and more particularly, an automobile configured to prevent the formation of scale due to foreign matter on the ABS wheel sensor and to reduce weight and reduce manufacturing costs. It relates to an ABS tone wheel sensor and a method of manufacturing the same.

As is well known, the anti-lock brake system (ABS) for automobiles allows the driver to smoothly operate the steering wheel by not locking the wheels completely under adverse conditions such as ice and rain. As a system for stopping a vehicle by a car, a tone wheel sensor that detects a rotation speed of a wheel is essential.

As described above, the tone wheel sensor for detecting the speed of the wheel in the ABS system of the vehicle is composed of a small serrated disc around the brake device inside the four wheels of the vehicle. The disc is also rotated at the same speed, and the sensor of four wheels is read by the sensor installed near the tone wheel, and the value is sent to the central computer (ecu), and the central computer continuously reads the rotation value and the wheel's rotation value. If this drops off or stops spinning, the brake pads that hold the wheels can be self-adjusted to provide the best conditions for braking.

In the ABS system for automobiles having the function as described above, the tone wheel sensor is composed of a disk 102 shaped like a small tooth 101 as shown in FIG. 1.

Since the ABS tone wheel sensor 100 is a product made by sintering metal powder, it is heavy, very expensive in manufacturing, and also by forming a scale by forming a scale by depositing foreign matter in a groove formed between the teeth 101. Since the information of the ABS system related to the rotational speed of the vehicle could not be accurately sensed at all times, it was not possible to send accurate information to the central computer, causing problems such as deteriorating the ABS function when the wheels were braked.

The ABS wheel sensor for automobiles of the present invention for solving the above problems is configured to have a light weight and the same outer diameter of the metal piece and the groove is not stepped to solve the disadvantage of forming a scale by the foreign matter,

The purpose of the present invention is to provide a manufacturing method of the car ABS wheel sensor for automobile which can produce and supply the car ABS tone wheel sensor as described above in a simple process at a low cost. .

The ABS wheel sensor for automobiles of the present invention for achieving the above object forms an outer ring with a configuration in which the inner ring and the space portion, and the groove and the metal piece are alternately repeated with a metal plate, and alternately formed between the space portion and the metal piece. The groove is made up of non-magnetic synthetic resin,

As described above, the ABS wheel sensor for automobiles is formed by blanking and forming a metal plate, and put into an injection mold to produce a synthetic resin, which is manufactured according to the accompanying drawings. Looking at the embodiment in detail as follows.

2 is a manufacturing process diagram of the tone wheel sensor according to the present invention, Figure 3 is a perspective view showing a tone wheel sensor according to the present invention, Figure 4 is a cross-sectional view of the tone wheel sensor according to the present invention, Figure 5 is a use state of the present invention It is an exemplary diagram showing.

The ABS tone wheel sensor 1 for automobiles according to the present invention is a metal plate made of magnetic material, and the inner ring 2 and the space portion 5, the groove 3, and the metal pieces 4 for installing inside the wheel are at regular intervals. To form the outer ring 6 in a repeated configuration,

A non-magnetic synthetic resin layer 6 is integrally formed in the groove 3 formed between the inner ring 2 and the space 5 and the metal pieces 4.

The manufacturing method of the ABS wheel sensor for automobiles having the above configuration will be described in detail.

1st process Blanking Process

A blank wheel sensor metal plate 11 in which a center hole 10 is drilled is prepared by blanking the metal sheet material.

2nd process Inner ring  Molding process

The inner ring 2 is formed by forming a circular wheel sensor metal plate 11 in which the center hole 10 is obtained in the first step by punching and using a die and forming a periphery of the hole.

3rd process home section Metal  Forming process

The grooves 3 and the metal pieces 4 are formed by blanking the circular wheel sensor metal plate 11 having the inner ring formed in the second step.

4th process Outer ring forming process

The inner ring 4 obtained in the third step is formed, and the outer ring 6 is formed by forming a groove and metal pieces using a punch and a die on a circular wheel sensor metal plate 11 on which the grooves 3 and the metal pieces 4 are formed. To be.

5th process injection and Demolding Process

Through the first to fourth process, the inner ring 2 is formed, the outer ring 6 is formed by the groove 3 and the metal piece 4, and the wheel sensor metal plate 11 having the space 5 is placed in the injection mold. The non-magnetic synthetic resin layer 7 is formed by injection molding between the outer ring 6 composed of the groove 3 and the metal piece 4 and the space 5 and the inner ring 2 by injection molding, and then finished.

In addition to the manufacturing process of the ABS tone wheel sensor, the wheel sensor metal plate is formed by forming a hole, a metal piece and a groove in a metal sheet by a single blanking process, and forming an inner ring and an outer ring by a single forming process, and injection from an injection mold It is also possible to manufacture a tone wheel sensor.

Since the ABS wheel sensor 1 for automobiles according to the present invention as described above has an inner ring 2 formed of a metal plate which is a magnetic material, it can have sufficient durability when installed inside the wheel and can be continuously maintained.

In addition, since the space portion 5 formed between the inner ring 2 and the outer ring 6 is filled with a synthetic resin layer 5 which is a nonmagnetic material, the distance between the inner ring 2 and the outer ring 6 is not narrow and is always constant. You can maintain the interval.

In addition, since the non-magnetic synthetic resin layer 7 fills the grooves 3 formed between the metal pieces 4, the foreign matters are accumulated in the grooves 3 during use, thereby completely preventing the scale from being formed. It will be able to accurately detect the information of the ABS system related to speed and send it to the central computer.

As described above, the ABS wheel sensor for automobiles of the present invention is composed of a metal plate and a synthetic resin, thereby reducing the weight and contributing to the weight reduction of the automobile. By solving the malfunction of the tone wheel sensor, it is possible to provide more reliable information about the rotational speed of the wheel to the central computer, and it is also possible to produce and supply the car ABS tone wheel sensor for automobiles in a simple process at low cost. have.
