Abstract

The utility model relates to a U-shaped thickness warning piece for a brake disc, which comprises a U-shaped structure formed by folding a strip-shaped metal piece and is characterized in that the outer end portion of one side of the U-shaped structure is turned over upwards, and a through hole for fixing a turnover portion on a disc type brake steel piece is arranged on the turnover portion. The U-shaped thickness warning piece for the brake disc is simple in structure and production process and capable of accurately and effectively detecting whether the brake disc of an automobile achieves the replacement thickness, thereby ensuring safe running of the automobile.

Description

U-shaped brake disc thickness caution sheet

Technical field

The utility model relates to a kind of U-shaped brake disc thickness caution sheet, is applied to the caution of braking automobile disc thickness.

Background technique

Brake block mainly is to be made up of through the high temperature compacting steel disc and friction material layer.In the braking automobile process, friction material layer and brake disc rub mutually, produce the power that makes automobile brake, and friction material layer constantly wears and tears, thereby makes the thickness of brake block more and more littler, when thickness reaches certain limit, must in time change brake block.Existing brake block mainly is divided into two kinds; A kind of is not have warning device; The brake block that is installed on the chuck in use generally is a usage degree of understanding product through specification, and (as: writing exactly on single kind products specification needs to change after this product uses the 1W kilometer) basically all is to judge the replacing brake block by this way; Change relatively waste in advance, change the untimely potential safety hazard that just has.A kind of in addition is exactly to adopt electronic alarm; And thickness will be reported to the police when reaching certain limit; The portions of electronics part of electronic alarm is installed in the friction material layer of brake block, and temperature is very high during owing to the friction material layer friction, so electronic alarm is very easy to damage; Be difficult to reach 100% warning effect, have bigger potential safety hazard.Therefore, people are badly in need of a kind of simple in structure, produce easily brake disc thickness caution sheet.

Summary of the invention

The purpose of the utility model is to provide a kind of U-shaped brake disc thickness caution sheet, has solved problems such as present brake disc thickness caution detection architecture complicacy, poor accuracy effectively, helps effectively warning brake disc thickness, thereby ensures vehicle safety travel.

The utility model is characterised in that: a kind of U-shaped brake disc thickness caution sheet; Comprise by strip sheet metal the U-shaped structure that constitutes after folding; It is characterized in that: wherein on one side the upwards turnover of outer end of said U-shaped structure offers in the said turnover portion and is used to be fixed in the through hole on the disk type brake steel disc.

The advantage of the utility model: the utility model structure and production technology are simple, and the ability precise and high efficiency detects automobile brake disc and whether reaches replacing thickness, thereby ensure vehicle safety travel.

Embodiment

With reference to figure 1; Fig. 2 and Fig. 3, a kind of U-shaped brake disc thickness caution sheet comprises by strip sheet metal the U-shaped structure that constitutes after folding; The wherein upwards turnover of 1 outer end on one side of said U-shaped structure offers the through hole 4 that is used to be fixed on the disk type brake steel disc 3 in the said turnover portion 2.

Above-mentioned turnover portion 2 and with the U-shaped structure at its place on one side 1 angle be 90 degree.

The practical implementation process: the through hole position of this device is connected on the disk type brake steel disc through fixed connecting pieces such as bolts, and the another side of caution sheet that makes the U-shaped structure then is towards brake block, and places on the flanking part of brake block.When the lengthening of vehicle brake sheet along with the vehicle driving time, thickness own will attenuation, can touch the caution sheet of this device when thickness is thinned to when wheel brakes once more, thereby send caution sound, reminds the brake block of driver's vehicle to need to change.

The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.

Claims

1. a U-shaped brake disc thickness is warned sheet; Comprise by strip sheet metal the U-shaped structure that constitutes after folding; It is characterized in that: wherein on one side the upwards turnover of outer end of said U-shaped structure offers in the said turnover portion and is used to be fixed in the through hole on the disk type brake steel disc.

2. U-shaped brake disc thickness according to claim 1 caution sheet is characterized in that: said turnover portion and with the U-shaped structure angle on one side at its place be 90 degree.
