Description
Technical Field
The utility model relates to a brake block technical field particularly relates to a take commercial car disc brake block of metal alarm.
Background
As the performance and the running speed of vehicles are increasing day by day, in order to increase the braking stability of the vehicles running at high speed, disc brakes become the mainstream of the current braking systems, and with the implementation of the GB7258-2017 standard, the standard increases the requirement that all wheels of a dangerous cargo transport semitrailer, a three-axle railing type semitrailer and a bin grid type semitrailer should be equipped with disc brakes, and more vehicles start to use disc brake pads.
The disc brake pad is formed by mutually attaching a steel backing and a friction material layer through high-temperature pressing. The disc brake device clamps a brake disc rotating along with a tire by a static brake disc to generate friction force, so that the rotating speed of a wheel is reduced. When the brake pedal is stepped on, the piston in the master cylinder is pushed, pressure is built in the brake oil path, the pressure is transmitted to the piston of the brake cylinder on the brake caliper through brake oil, and the piston of the brake cylinder moves outwards and pushes the brake pad to clamp the brake disc after being pressurized, so that the brake pad and the brake disc are rubbed to reduce the rotating speed of the wheel, and the automobile is decelerated or stopped. In the braking system of the automobile, a brake pad is the most critical safety part, and the quality of all braking effects plays a decisive role.
Because the brake disc of the disc brake is exposed in the air, the disc brake has excellent heat dissipation performance, when the vehicle is subjected to emergency braking in a high-speed state or is subjected to repeated braking in a short time, the braking performance is not easy to decline, and the vehicle can obtain a better braking effect so as to improve the safety of the vehicle.
When the brake pad is used to a certain thickness, the steel back is directly abraded with the brake disc due to the abrasion of the friction material, the brake disc is damaged by pulling, and the brake failure is caused to cause accidents. Therefore, a brake pad capable of automatically giving an alarm signal after the brake pad is worn to a specified position is needed at present.
The commercial vehicle disc brake pad with the alarm in the current market. The alarm is welded on the steel back in the commonly adopted manufacturing process, and the using effect can be achieved. However, because of the influence of unstable factors such as current and the like in the welding process, the alarm and the disc are easy to directly break off after welding, so that the alarm sound of high-frequency scream cannot be generated, the welding process efficiency is low, and the manufacturing cost is relatively high.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the brake pad which can automatically send out the alarm signal after the brake pad is worn to the specified position and has low cost and stable fixation is provided.
The utility model provides a take commercial car disc brake block of metal alarm, includes brake block body and alarm device, the brake block body on be equipped with a fixed port, fixed port include fixed part and intercommunication portion, the fixed part in be equipped with a fixed plate, alarm device on with the fixed plate on be equipped with the fixed orifices that corresponds each other, alarm device pass through rivet fixed connection and be in the fixed plate on.
At first the utility model adopts the above structure, in the use of brake block, because the continuous wearing and tearing of brake block, wear to the position that the regulation required to be changed when the brake block, can directly wear and tear alarm device, alarm device takes place the police dispatch newspaper to remind the user to change the brake block, the utility model has the advantages of can send alarm signal automatically, and with low costs, fixed stable.
Preferably, the brake pad body is provided with a longitudinal groove, and the longitudinal groove is communicated with the communication part.
The utility model discloses set up vertical groove on the brake block body to the concentrated stress that the brake block received among the dispersion brake process, thereby can improve the utility model discloses a stability.
Preferably, the alarm device comprises a connecting part and a sensing part, the fixing hole is positioned on the connecting part, and the sensing part is positioned in the communicating part.
The utility model adopts the above structure, fix through connecting portion, improved on the one hand the utility model discloses a stability, on the other hand improve former welded connected mode for with rivet connection to avoided because of receiving unstable factors influence such as current among the welding process, the alarm directly collapses out very easily with the dish contact after the welding, lead to not sending the warning sound of high frequency scream, and welding process is efficient, the relatively higher defect of manufacturing cost.
Preferably, the brake pad body comprises a brake pad upper part and a brake pad lower part, the brake pad longitudinal groove is positioned on the brake pad lower part, the brake pad lower part comprises inclined parts and a middle part which are positioned on two side edges of the brake pad lower part and are bilaterally symmetrical, the inclined parts and the middle part are fixedly connected, and the cross-sectional area of the inclined parts is gradually increased from outside to inside.
The utility model discloses a structure of rake has reduced stress concentration on the one hand, and on the other hand can be so that the rake can contact from the edgewise and play the supporting role in the wearing and tearing process of brake block to improve the stability in the use.
Preferably, the brake pad body is provided with an arc-shaped sunken part, and the sunken part is communicated with the longitudinal groove.
The utility model discloses an arc depressed part, this structure can disperse stress simultaneously and improve the stability of brake block at the fixed of the brake block of being convenient for.
Preferably, the sensing portion and the longitudinal groove are parallel to each other.
The above structure of the utility model is adopted, in the use, help preventing that the brake block from receiving influences such as vibrations and making response portion and brake block body take place to contact to the false alarm appears, improved the utility model discloses an accuracy.
The beneficial effects of the utility model reside in that: 1. the utility model has the advantages of wearing and tearing can automatic alarm signal's after to the regulation position effect, the accuracy is high, 2 the utility model discloses a multiple structure dispersion brake block's internal stress to improved the steadiness of brake block, 3 the utility model has the advantages of with low costs, fixed stable.
