Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in fig. 1-6, the utility model provides a technical solution: the utility model provides a sensor of drum-type automobile brake piece wearing and tearing warning, evenly sets up bush body 1 that has the hole and places contact 4 in bush body 1 including the surface, the top of contact 4 is equipped with a bulge, install the sensing line that is connected with vehicle alarm display in the contact 4, the vertical opening of having seted up on bush body 1, be equipped with a plurality of link plates 2 that are used for contacting with brake shoe friction disc inner wall on bush body 1, be equipped with a plurality of dogs 5 of integrated into one piece on bush body 1, the bottom of bush body 1 is equipped with a plurality of supporting shoes 6 of integrated into one piece, just 6 joints of supporting shoe are in the draw-in groove that sets up in contact 4 lower parts.

As an example, the bushing body 1 is made of a high temperature resistant metal material. Because the maximum temperature of the friction plate can reach 350 ℃ when the automobile brakes, the high-temperature resistant metal material refers to a metal material with the melting point above 350 ℃, and preferably a material with high melting point and low price, such as beryllium copper, stainless steel or spring steel, and the like, the bushing body 1 has good high-temperature resistant effect, the deformation caused by high temperature can not occur, and the normal use of the contact 4 can not be influenced.

Preferably, the number of the hanging plates 2 and the stop blocks 5 is two or three. The most suitable bushing body 1 can be selected for installation according to actual requirements.

As an example, as shown in fig. 1, a protective sleeve 3 extending to the inside to cover the sensing wire is inserted below the contact 4. After the protective sleeve 3 is inserted into the contact head 4, the sensing wire can be protected and fixed.

As an example, as shown in fig. 1 to 5, the side surface of the bushing body 1 is provided with a spring piece which is integrally formed and protrudes inward to contact with the contact 4. When the contact 4 is plugged into the bushing body 1, the contact 4 presses the spring, thereby further fixing the contact 4.

The stopper 5 is provided to fix the bushing body 1 to the brake shoe, and may be constructed in various forms, for example, as shown in fig. 3, the stopper 5 extends upward from the inner top surface of the bore of the bushing body 1 in an inclined manner and forms an angle of 40 ° with the bushing body 1. The stopper 5 may also be inclined and extended upwards from the inner bottom surface of the hole of the bushing body 1 and form an angle of 15 degrees with the bushing body 1, as shown in fig. 2. Or as shown in fig. 4, the stopper 5 extends obliquely upward from the inner bottom surface of the hole of the bushing body 1 and forms an included angle of 40 degrees with the bushing body 1. The stop blocks 5 with the three structures can clamp the brake shoe friction plate by the lining body 1.

According to the above technical scheme, the utility model discloses a working process does: the lining body 1 is extruded firstly and placed into a friction plate, so that the hanging plate 2 is hung on the top surface of a brake shoe, the stop block 5 on the lining body 1 supports against the bottom surface of the brake shoe, meanwhile, the number of the hanging plate 2 and the stop block 5 can be adjusted to two or three according to actual requirements, so that the lining body 1 is fixed, the contact head 4 can be made of ceramic, bakelite, plastic or resin, and then the contact head 4 is placed into the lining body 1, so that when the brake shoe friction plate is rubbed to a certain degree, when the brake shoe friction plate is continuously used, a sensing wire exposed out of the contact head 4 is directly abraded, the power supply of the sensing wire and an alarm display is cut off, an alarm switch of the alarm display is turned on, and the alarm display of a vehicle timely reminds a driver.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
