On the vehicle of Japan and France, have drag friction pad wear warning device, but existed following shortcoming:
1, this warning device only carries out the wear limit warning to the thickness of friction lining, but can not give newspaper to wear limit, if limiting alarm occurs in the driving way, causes great difficulty then for driver's renewal of facing.
2, this technology is to the loosening of friction lining with break and can not report to the police.
Task of the present utility model be to provide a kind of to the loosening of brake strip and break, wear limit, wear limit give announcement, the multi-function device of Bao Jinging promptly and accurately makes friction lining in time be changed, guarantee the safety of driving a vehicle.
This task is to realize by improvement and innovation to existing wearing and tearing warning device.The technical scheme of existing wearing and tearing warning device is that a contact is placed by the friction lining.Because of being loaded on the brake shoe, when friction lining is arrived the thickness that must change by wear down, if row braking again, this moment, brake drum can touch contact connection direct current circuit simultaneously, the bright realization of indicator lamp that is contained in operator's compartment is reported to the police (referring to accompanying drawing 3, B is a friction lining end position cambered surface among the figure, and C is the brake drum cambered surface)
The improved part of the utility model is: a metal contact of prior art is increased to two.These two metal contact all are packed on the contact base made from insulating material.And contact base is assemblied on the brake shoe, and the head of contact base stretches among the cavity that precasts on the friction lining.The setting height(from bottom) of two metal contact does not wait, and the wear limit position of the top of one of them metal contact and friction lining (being alert locations) is contour: and another metal contact and wearing and tearing give the newspaper position contour.The afterbody of two metal contact connects with a plus terminal respectively and connects with the wear limit display lamp that is installed in operator's compartment by a lead respectively.So, when friction disc wear when brake drum touches long metal contact, connect wear limit and give the newspaper indicator lamp, the driver can be according to also with the mileage that travels, whether decision should renewal of facing.When friction lining continues to may wear to brake drum and touches short metal contact, connect the wear limit warning indicator lamp, notify the driver renewal of facing immediately.
The part of the utility model innovation is: tighten inlaying in the metal at the top of contact base pillow block and encircle, the outside of ring also has a metal outer shroud in the metal, the metal outer shroud tightly is set in the hole that precasts on the friction lining, and the metal inner and outer interannular keeps a less clearance.The metal outer shroud joins by a plus terminal and positive source, and ring joins with the loosening telltale of friction lining in the metal.When friction lining took place to become flexible, the metal inner and outer loop contacts so connect the loosening display lamp of friction lining, notified the driver should repair or renewal of facing.
