Problems solved by technology

[0007] The invention aims at the above-mentioned problems such as abnormal wear of the brake disc and the brake pad caused by the free swing of the single-point brake caliper unit during the running of the existing rail vehicle, and provides an automatic alignment device for the brake caliper unit. The middle device, brake caliper unit, limit alarm method and installation method can avoid abnormal wear caused by the free swing of the brake caliper unit, and can automatically prompt to replace the brake pads when the brake pads are worn to the limit

Embodiment Construction

[0045] Hereinafter, the present invention will be described in detail through exemplary embodiments. However, it should be understood that without further description, elements, structures, and features in one embodiment can also be beneficially combined into other embodiments.

[0046] In the description of the present invention, it should be noted that the terms “upper”, “lower”, “left”, “right”, “inner”, “outer”, etc. indicate the orientation or positional relationship based on the drawings. The positional relationship is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes, and cannot be understood as i...

Abstract

The invention relates to an automatic centering device, a brake clamp unit, a limit alarm method and an installation method. The automatic centering device comprises a first mounting seat assembly. asecond mounting seat assembly, a first elastic assembly and a second elastic assembly, wherein the second mounting seat assembly and the first mounting seat assembly are symmetrically mounted and havethe same structure; the first end part of the first elastic assembly is hinged with the first mounting seat assembly; the first end of the second elastic assembly is hinged to the second mounting seat assembly, and the second end of the second elastic assembly is hinged to the second end of the first elastic assembly through a hinge part; and the first elastic assembly and the second elastic assembly are the same in length and elastic force value. According to the automatic centering device, abnormal abrasion caused by free swing of the brake clamp unit can be avoided, and replacement of a brake pad can be automatically prompted after the brake pad is abraded to the limit.

Description

Technical field [0001] The invention belongs to the technical field of rail transit, and relates to rail transit braking technology, in particular to an automatic centering device for a brake caliper unit, a brake caliper unit, a limit alarm method and an installation method. Background technique [0002] The brake caliper unit is the actuator of the rail vehicle brake system, which is used to convert the compressed air pressure into mechanical reasoning and amplify, and realize the conversion of the kinetic energy of the rail vehicle through the friction between the brake disc and the brake pads. To achieve the purpose of speed regulation or parking. In the process of converting the kinetic energy of rail vehicles into heat energy, the wear between the brake discs and the brake pads is mainly the brake pads, and the replacement of the brake pads is more frequent. In general, the braking of high-speed EMUs The replacement period of brake pads is about 6 months. For ordinary rail...
