Background technique
Friction plate is the visual plant in the Vehicular brake device; and also be vehicle one of the bigger parts that in use wear and tear; vehicle in use often uses friction plate to force vehicle deceleration, parking; therefore friction plate can grind thinner and thinner; when wearing and tearing arrive certain limit; must change, otherwise can bring driving hidden danger, crisis driver and passenger's safety.Because the behaviour in service difference of each vehicle, the friction disc wear that has is very fast, be less than maintenance and just must change, and the use that has is less, if blindly change during maintenance, will cause waste.
Summary of the invention
In view of this, the invention provides a kind of mechanical audible alarm friction plate, the technical problem of its solution is when friction plate arrives wear limit, can in time report to the police by sound, remind the driver to change, belong to pure mechanical structure simultaneously, do not need external equipment, cost is lower; The present invention also provides a kind of mechanical audible alarm friction plate, and it sends the alarm sound prompting and changes when friction plate arrives wear limit, change easily simultaneously.
Purpose to one of the present invention provides a kind of mechanical audible alarm friction plate, comprise the friction plate body, also comprise friction sounding piece, described friction sounding piece to small part is arranged in the friction plate body, the end that described friction sounding piece is arranged on friction plate inside is contact sounding end, when friction disc wear is to the utmost point prescribed a time limit, the contact sounding end of described friction sounding piece and brake drum or brake disc come in contact and cause friction sounding piece and send mechanical chimes of doom, and described friction plate body is the worn and torn section of friction plate towards the outer surface of brake drum or brake disc with contacting between the sounding end.
Further, described friction sounding piece is resilient sheet-like structure or boss structure.
Two of purpose of the present invention provides a kind of mechanical audible alarm brake pad, comprise brake shoe assembly and the friction plate body that is arranged on the brake shoe assembly, also comprise friction sounding piece, described friction sounding piece to small part is arranged in the friction plate body, the end that described friction sounding piece is arranged on friction plate inside is contact sounding end, the other end of described friction sounding piece is fixedlyed connected with brake shoe assembly, when friction disc wear is to the utmost point prescribed a time limit, the contact sounding end of described friction sounding piece and brake drum or brake disc come in contact and cause friction sounding piece and send mechanical chimes of doom, and described friction plate body is the worn and torn section of friction plate towards the outer surface of brake drum or brake disc with contacting between the sounding end.
Further, described friction sounding piece is resilient sheet-like structure or boss structure;
Further, an end that is connected with brake shoe assembly of described friction sounding piece adopts punching press, welding or riveted way to fixedly connected with brake shoe assembly.
The invention has the beneficial effects as follows:
The present invention is arranged on the friction plate body by the sounding piece that will rub, thereby do not need to be installed on brake shoe or the brake slipper, make friction plate become an independently product, and do not need external other energy or audible device, when friction disc wear arrives design thickness, the brake drum of friction sounding piece and rotation or brake disc rub mutually and produce vibrations and send ear-piercing auditory tone cues replacing brake disc assembly, it installs simple, low cost of manufacture, and when changing, only need more renewal of facing renewal, also reduced user cost; Simultaneously, its production technology only need be used traditional manufacturing process, and it goes without doing too many improvement does not need to transform traditional braking component in the realization of integral stop, so manufacturing of the present invention is simple, cost is relatively low, and is safe and reliable.
Other advantages of the present invention, target, to set forth in the following description to a certain extent with feature, and to a certain extent,, perhaps can obtain instruction from the practice of the present invention based on being conspicuous to those skilled in the art to investigating hereinafter.Target of the present invention and other advantages can realize and obtain by following specification and claims.
