Low-temperature-resisting automobile brake caliper and detection device thereof

Abstract

The invention provides a low-temperature-resisting automobile brake caliper and a detection device thereof. The low-temperature-resisting automobile brake caliper and the detection device thereof solve the technical problems that according to an existing brake, a sealing ring is adopted to seal a piston and a cylinder body, a brake works unsteadily due to the fact that the sealing ring is failed and oil leakage occurs when the sealing ring operates in the low-temperature environment for a long time, and no device for detecting a brake exists. The low-temperature-resisting automobile brake caliper comprises a U-shaped shell. The inner side walls of the two U-shaped edges of the shell are provided with piston cavities respectively. The closed end of the shell is provided with a drive cavity communicated with the two piston cavities. The drive cavity is provided with an oil inlet hole communicated with the outside. Pistons are arranged in the piston cavities. One end of each piston is capable of being located in the corresponding piston cavity, and the other end of each piston is fixedly provided with a brake piece. Elastic isolation pieces are further fixed between the piston cavities and the drive cavity. The portions between the elastic isolation pieces and both the piston cavities and the drive cavity are sealed. The low-temperature-resisting automobile brake caliper and the detection device have the advantages that working stability is good, and whether oil leakage occurs in the automobile brake caliper or not can be detected.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a low-temperature-resistant automobile brake caliper and a detection device thereof. Background technique [0002] In the process of driving a car, one of the most commonly used actions is to brake. In order to avoid obstacles in front of you, or to maintain speed when driving downhill, you need to use the braking system of the car, and the realization of all these actions The core component is the car brake caliper. Automobile brake calipers refer to the parts that produce the force (braking force) that hinders the movement or movement tendency of the vehicle, which also includes the retarder in the auxiliary braking system. The two most common types of brakes we have are drum brakes and disc brakes. [0003] After searching, for example, Chinese patent literature discloses a disc brake [application number: 201010621498.5; authorized announcement number: CN 102094912A]. The d...

Problems solved by technology

[0004] Although the housing in the brake disclosed in this patent can be applied to discs with various specifications, the brake uses a sealing ring to seal the piston and the cylinder. Because the sealing ring will fail and leak oil during long-term low-temperature environment work, Cause the brake to work unstable, and there is no device for detecting the brake, therefore, it is necessary to design a low temperature resistant automobile brake caliper and its detection device
