Description

Brake pad and disc brake

Technical Field

The utility model belongs to the technical field of the stopper, concretely relates to brake block and disc brake.

Background

During braking of an automobile, the friction material is gradually worn by the brake pad due to friction. The brake pad needs to be replaced in time after the friction material is used up, otherwise, the braking effect is lost and the brake disc is damaged; brake sensitivity is also affected when the friction material is worn too thin. The service distance of the conventional brake pad in the market is 30000-60000 kilometers, and in the service period, the excessive abrasion of the brake pad is not easy to attract the attention or attach importance of owners, so that much inconvenience is brought to the daily maintenance of the owners, and meanwhile, great potential safety hazards exist.

Chinese patent application No. CN201710468143 discloses a brake pad for an automobile disc brake, when a friction block is ground to a warning line, an alarm pad can vibrate with a brake disc in a friction manner to generate harsh sound, so as to achieve an alarm reminding function, and an automobile owner can know that the friction pad needs to be replaced by hearing the sound of the alarm reminding. However, the method of reminding the car owner of the impending excessive wear of the brake pad by using the sound generated by the friction vibration is easy to cause traffic noise pollution, and the sound of the alarm reminding is also easy to be interfered by factors such as outdoor environment, window closing and the like to influence the effect of the alarm reminding. Meanwhile, under the condition of parking of the vehicle, the method for generating sound by using friction vibration cannot realize the effect of warning and reminding, and the invention has larger change on the structure of the traditional brake block, thereby increasing the production and manufacturing cost.
