What is the brake caliper of a car? What is the brake bracket? The brake caliper refers to the caliper disc brake, which is a kind of disc brake. Its rotating element is a metal disc with an end face, called a brake disc.
The fixed element is a brake pad composed of a friction pad with a small working area and its metal back plate. There are 2 to 4 in each brake. These brake pads and their actuating devices are installed across the brake disc. In the clamp-shaped bracket, it is collectively called the brake caliper. The brake disc and brake caliper together constitute a caliper disc brake. According to the installation position, the brake can be divided into wheel brake and central brake. The brake whose rotating element is fixed on the wheel or half shaft is called the wheel brake; the brake whose rotating element is fixed on the drive shaft of the transmission system is called the central brake. Wheel brakes are generally used for service braking, but also for emergency braking and parking braking.
Advantages:(1) The working surface of the disc brake is flat and both sides transfer heat. The rotation of the disc is easy to cool and not prone to large deformation;(2) There is no potential effect, the brake performance is less affected by the friction coefficient, and the braking performance is relatively stable;(3) The thermal expansion of the brake disc along the thickness direction is small. Even if the brake disc expands due to high temperature after long-term use, the braking effect will be enhanced;(4) small size and mass;(5) It is easy to realize automatic adjustment of the gap, and the maintenance is simple;(6) The efficiency is reduced after immersion, and only one or two brakes can return to normal.
Brake is a Chinese word, and the pinyin is zhìdòng, commonly known as "brake". The action of stopping or reducing the speed of a running locomotive, vehicle and other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, and install a corresponding brake shoe, belt or disc on the base to generate braking torque under the action of external force.
Bracket, commonly known as steel bracket, the substrate of ordinary movable teeth is plastic, while the bracket turns the plastic base into alloy material. Of course, the material of teeth is unchanged, or resin teeth, with similar color and luster to natural teeth. The advantage of the bracket denture is that the thickness of the base is very thin, the thickness of the conventional plastic base is about 2mm, while the thickness of the alloy base is only about 0.5mm, thus reducing the foreign body feeling in the oral cavity of the denture and increasing the comfort. And the alloy has high strength, is not easy to crack, and does not affect the appearance. Bracket type movable denture has been widely used. In particular, the pure titanium stent, its weight is the 1/3 of ordinary metal stents, and has good biocompatibility, as the ideal stent material of the movable denture.

The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking decreases in dynamic loads. In some important occasions, we will take some anti-loose measures to ensure the reliability of nut locking. Locking nut is one of the anti-loose measures.
