Abstract
The utility model relates to a thickness alarming device for a ventilated brake disc of a car. The thickness alarming device comprises the ventilated brake disc, wherein the ventilated brake disc is provided with a trough which is internally provided with the top part of an alarming spring piece; the bottom part of the alarming spring piece is connected with the top part of a clamping spring by a connector; two connecting ribs of the brake surface of the ventilated brake disc are respectively provided with a groove corresponding to the trough; and the bottom part of the clamping spring is arranged in the grooves. The thickness alarming device has the beneficial effects that elastic lapping edges of the alarming spring piece are elastic, and when the brake surface of the brake disc is worn to minimum thickness, the parts, protruding the brake surface of the brake disc, of the elastic lapping edges of the alarming spring piece generate friction with a brake piece to generate a sound so as to remind a driver of replacing the brake disc.
Description
Technical field
The utility model relates to a kind of automotive ventilation disc thickness value warning device.
Background technique
The braking system that automobile is commonly used has two kinds, and a kind of is drum brake, and another kind is a disc type brake.Disk type braker is made up of brake disc and brake calipers.The brake disc shape also is made of metal as the thin slice rotating disk of lazy Susan, with the coaxial rotation of wheel.Brake calipers is fixing not to be changeed, and it forms " jaw type " across the both sides at brake disc.In the braking process, driving mechanism impels brake calipers to clamp the both sides card of brake disc, and the braking plate of inlaying on the pincers is friction brake disk tempestuously, forces its rotating speed to reduce until stopping.
Ventilated brake disc is the brake disc that the ventilation hole slot is arranged in the middle of the graduated dial, is the common a kind of structure of brake disc.Brake disc was in using, and brake lining can be because of constantly attenuation of brake wear.Ventilated brake disc all has the requirement of brake lining minimum thickness value when design, will in time change brake disc if reach this numerical value.If the brake lining one-tenth-value thickness 1/10 of brake disc reaches or less than the minimum thickness value, its braking ability will reduce greatly so.If the braking plate that is used with this brake disc has also worn down very severely, will cause brake caliper piston from caliper, to come off, have a strong impact on car load safety.So will in time change the brake disc that reaches the minimum thickness value.Existing technology obtains the brake lining one-tenth-value thickness 1/10 through detecting brake disc, can not judge in time whether brake disc reaches the minimum thickness value, can produce potential safety hazard.
The model utility content
The purpose of the utility model provides a kind of automotive ventilation disc thickness value warning device; Detect brake disc with passing through of overcoming that existing technology exists and obtain the brake lining one-tenth-value thickness 1/10; Can not judge in time whether brake disc reaches the minimum thickness value, can produce the deficiency of potential safety hazard.
The purpose of the utility model is to realize through following technological scheme:
A kind of automotive ventilation disc thickness value warning device; Comprise ventilated brake disc; Offer groove on the ventilated brake disc; The length of said groove equals the minimum thickness value of the brake lining permission of brake disc, the top that the warning spring sheet is installed in the said groove, and the bottom of warning spring sheet is connected with the top of jump ring through link; Be respectively equipped with the groove of corresponding groove on two connecting tendons of the brake lining of ventilated brake disc, the bottom of said jump ring is installed in the groove.
Further, said warning spring sheet is made up of U-shaped main body one and the elasticity scrap (bridge) that is connected two ends, U-shaped main body one top, and the elasticity scrap (bridge) is fastened in the said groove.
Further, said jump ring is made up of U-shaped main body two and the elasticity edge that is connected the two ends at U-shaped main body two tops, and the elasticity edge is fastened on respectively in two said grooves.
The beneficial effect of the utility model is: the elasticity scrap (bridge) of warning spring sheet has elasticity; When the brake disc brake lining wears up to the minimum thickness value; By the part and the braking plate friction-produced sound of the elasticity scrap (bridge) of warning spring sheet protrusion brake disc brake lining, change brake disc to remind the driver.
