Description
Technical field
A kind of warning member of brake is the utility model is related to, more particularly, to a kind of drum brake electronics report
Alert component.
Background technology
Drum brake is widely used in various small-sized, medium-sized and heavy vapour, on lorry, with the hair of automobile industry
Exhibition, the timely and convenience requirement of maintenance and replacing of the people to the various parts of vehicle are increasingly richer high.
Drum brake on the tire of vehicle, can not see making for each parts on brake by closed from outside
With situation, and the service life of vehicle is very long, much larger than the service life of each parts on brake, makes when each parts reach
With just needing to be changed during the life-span；Two brake-shoes belong to wear-out part wherein on brake, and service life is far smaller than whole
The service life of car is, it is necessary to repeatedly be changed.And replacement cycle no accurately requirement and the criterion of brake-shoe, but
Assessing inaccuracy may cause：
First, Brake shoe lining is not completely worn out：Determine friction plate whether may wear to the limit, it is necessary to by entire vehicle tyre and
Brake drum is pulled down, and causes to waste if abrasion not exclusively directly changes brake-shoe；If brake-shoe is changed without by tire and system
Dynamic drum, which installs, to be continuing with, and also needs that the disassembly and installation of tire and brake drum, wasting manpower and material resources are repeated several times.
2nd, Brake shoe lining excessive wear：Normal wear is carried out with brake drum is friction facing on brake-shoe, is rubbed
The contact wear effect for wiping liner and brake drum is normal attrition, will not destroy the working face of brake drum, but work as and rub
Wiping liner, all abrasion is not changed but in time, can cause brake drum with supporting the shoe contact of friction facing to grind
Damage, and shoe brake can cause brake drum to scratch with brake drum wear, or even braking action is not had, when changing brake-shoe also
Need together to change brake drum, and the cost of brake drum is very high, can cause greatly to waste.
No matter Brake shoe lining wears not exclusively or worn excessively, can all cause the waste of substantial amounts of manpower and materials.
Utility model content
In order to solve the problems, such as that the replacement cycle of vehicle brake-shoe in the prior art assesses difficult, the purpose of this utility model

Head of the reverse bead formed on wire seat as electronic warning component, head are wound in the middle part of the wire
It is fixed on by rivet on the preposition tendons of beef, mutton or pork of preposition brake-shoe, the preposition shoe plate of preposition brake-shoe is provided with runs through logical for head
Groove, is provided with the groove for head embedment on the preposition friction plate of the preposition shoe plate of preposition brake-shoe, and head is through preposition
It is embedded to after the groove of shoe plate in the groove of preposition friction plate；During the preposition friction disc wear of drum brake, pass through
The head contact of wire is to disconnecting after brake drum wear so that warning circuit occurs open circuit and alarmed.
The gum cover is fixed on the preposition tendons of beef, mutton or pork by the 3rd line card, and the 3rd line card one end is connected preposition by buckle structure
The tendons of beef, mutton or pork, the other end are provided with the neck for being used for fixing gum cover.
In described electronic warning component, pass the wire both ends after gum cover and drum brake is then passed through by rubber stopper
Hole on back-plate is connected with interface hull.
The beneficial effects of the utility model：
The utility model realizes timely feedback when Brake shoe lining in drum brake may wear to the limit, solves
In drum brake in use brake-shoe can not accurately, the defects of timely being changed.
The utility model relative to current drum brake brake-shoe use, that the replacement cycle provides accurate signal is anti-
Feedback, avoid using drum brake vehicle after sale in substantial amounts of manpower and materials waste.

Embodiment
The utility model is described in further detail with specific implementation below in conjunction with the accompanying drawings.
As Figure 1-3, electronic warning component 9 of the present utility model is fixed on the preposition brake-shoe of drum brake,
Preposition brake-shoe includes the preposition tendons of beef, mutton or pork 8, preposition shoe plate 11 and preposition friction plate 12, and electronic warning component 9 includes wire seat 1, led
Line 2, gum cover 3 and interface hull 5, the middle part of wire 2 are wound in the guide groove of wire seat 1, and wire seat 1 is fixed on the preposition tendons of beef, mutton or pork 8
On, the both ends of wire 2 are arranged in gum cover 3 after being laid out from wire seat 1, are wrapped up the wire 2 for stretching out guide holder 1 with gum cover 3, wire 2
Both ends are extend into the wire guide of the one end of interface hull 5 after passing gum cover 3, and the other end of interface hull 5 is connected with warning circuit.
Interface hull 5 tightens up wire 2 with the collective effect of gum cover 3；The other end of interface hull 5 has corresponding with auto alarm circuit
The matched electric connection of joint.
As shown in figure 1, the middle part of wire 2 is wound on the reverse bead formed on wire seat 1 as electronic warning component 9
Head X, head are located at the limit of wear position of shoe friction plate.As shown in figure 4, head X is fixed on preposition brake-shoe by rivet 7
The preposition tendons of beef, mutton or pork 8 on, slotted on the preposition shoe plate 11 and preposition friction plate 12 of preposition brake-shoe, the preposition shoe plate of preposition brake-shoe
11 are provided with the groove run through for head X, are provided with the preposition friction plate 12 of the preposition shoe plate 11 of preposition brake-shoe for head X
The groove of embedment, head X ends are embedded in the groove of preposition friction plate 12 after passing through the groove of preposition shoe plate 11；In drum-type system
In the wear process of preposition friction plate 12 of dynamic device, touched after brake drum 14 wears and disconnected by the head X of wire 2 so that report
Alert circuit occurs open circuit and alarmed.
Gum cover 3 is fixed on the preposition tendons of beef, mutton or pork 8 by the 3rd line card 10, before the one end of the 3rd line card 10 is connected by buckle structure
Put the tendons of beef, mutton or pork 8, the other end is provided with the neck for being used for fixing gum cover 3, the neck of the 3rd line card 10 gum cover 3 is fixed it is achieved thereby that
The wire harness part of electronic warning component 9 is fixed, and controls the trend and beam positions of alarm assemblies.
First line card 4 is used to fix gum cover 3 in automobile chassis relevant position, realizes trend of the alarm on chassis and solid
It is fixed.
Second line card 6 is used for fixed interface housing 5 in automobile electronic circuit, makes interface hull 5 with corresponding to coupling
