Problems solved by technology

[0002] The friction plate is an important piece of equipment in the vehicle braking device, and it is also one of the parts that wear out during the use of the vehicle. During the use of the vehicle, the friction plate is often used to force the vehicle to slow down and stop, so the friction plate will become thinner and thinner , when the wear reaches a certain limit, it must be replaced, otherwise it will bring hidden dangers to driving and endanger the safety of drivers and passengers
Due to the different usage conditions of each vehicle, some friction plates wear out quickly and must be replaced before they are overhauled, while some are less used. If they are replaced blindly during overhaul, it will cause waste

Embodiment 1

[0021] Such as figure 1 , figure 2 As shown, the mechanical sound alarm friction block of the present utility model includes a brake shoe assembly 1 and a friction plate body 2 arranged on the brake shoe assembly 1, and also includes a friction sounding block 3, and the friction sounding block 3 is partially set In the friction lining body 2, one end of the friction sounding block 3 disposed inside the friction lining body 2 is the contact sounding end, and the other end of the friction sounding block is fixedly connected with the brake shoe assembly by stamping, welding or riveting. Between the outer surface of the friction lining body 2 facing the brake drum or brake disc and the contact sounding end is the wearable section of the friction lining body. When the friction lining body 2 wears to the limit (such as figure 2 As shown in , when it wears to the value d, which is equal to the length of the part of the friction sounding block arranged in the friction plate body 2)...

Embodiment 2

[0024] Such as image 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the friction sounding block adopts a boss structure, wherein the boss is arranged in the friction plate body 2, and the front end of the boss is set to contact the sounding end, when the friction plate body 2 When the wear reaches the limit, the contact sounding end of the friction sounding block 3 will come into contact with the brake drum or brake disc, thereby causing an alarm sound.

Embodiment 3

[0026] Such as Figure 5 , Figure 6 As shown, the difference between the present embodiment and the second embodiment is that the friction sounding block adopts a pin-type boss structure.

Abstract

The invention discloses a mechanical audible alarm friction plate, comprising a friction plate body and a friction sounding block, wherein, at least part of the friction sounding block is arranged in the friction plate body; one end of the friction sounding block arranged in the friction plate is a contact sounding end, when the friction plate is abraded to an extreme limitation, the contact sounding end of the friction sounding block is contacted with a brake drum or a brake disk to trigger the friction sounding block to send out a mechanical warning sound; an abrasion section of the friction plate is arranged between the outer surface of the friction plate body toward the brake drum or the brake disk and the contact sounding end. Through arranging the friction sounding block on the friction plate body, the mechanical audible alarm friction plate of the invention needs not to be installed on a brake shoe or a brake block to lead the friction plate to be an independent product, needs not to be externally connected with other energy or sounding equipment; the mechanical audible alarm friction plate of the invention has simple installation, lower manufacturing cost, only the friction plate needs to be changed in replacement, thus reducing usage cost.

Description

technical field [0001] The invention relates to a friction plate used for matching with a brake drum or a brake disc when braking an automobile, in particular to a mechanical sound alarm friction plate and a friction block.
