The disc brake is widely applied to cars, passenger cars and dangerous goods vehicles, most of the cars are used for all wheels at present, and a few cars are only used as front wheel brakes and are matched with drum brakes of rear wheels, so that the cars have higher direction stability during braking. In commercial vehicles, disc brakes are increasingly being used today in new and high-end vehicle models.
The disc brake is of an air pressure type and is controlled by air pressure, and main parts comprise a brake disc, an air chamber, a brake caliper, a support and the like. The disc brake has the advantages of fast heat dissipation, light weight, simple structure and convenient adjustment. Particularly, the high-temperature-resistant performance is good under high load, the braking effect is stable, the muddy water invasion is not afraid, the car runs in winter and in bad road conditions, the disc brake adopted by many cars comprises a plane type brake disc, a punched type brake disc and a ventilation type brake disc, and the braking effect and the ventilation and heat dissipation capacity of the ventilation type brake disc are good.
For example, in patent CN108779818A a disc brake is mentioned, comprising a brake caliper overlapping at least one brake disc and a brake actuation mechanism arranged inside said brake caliper and having: -an amplification mechanism comprising a brake lever rotatable about a pivot bearing to introduce a clamping force from an actuator; -a thrust element transmitting the amplified clamping force onto the brake disc, characterized in that a force redirection means for transmitting an input force from the actuator to the brake lever is arranged between the actuator and the brake caliper.
