Description
Technical field
The utility model belongs to Pneumatic drum brake field, and in particular to a kind of Pneumatic drum system equipped with wear indicator
Dynamic device.
Background technique
In pneumatic drum brake, the friction disc wear feelings of the commercial vehicle pneumatic drum brake of most domestic
Condition is checked by the peep hole on dust blocking tray, by estimating the thickness surplus of friction plate to determine whether needing replacing.
It is that can not accurately judge whether friction plate has worn out extreme position under normal conditions.If friction plate not may wear to the limit
Position, replacement will cause certain waste in advance；If friction plate has worn away extreme position and replaces not in time, will cause rivet with
Brake drum contact, scratches brake drum, shortens the brake drum service life, influences braking ability.So driver needs timing to observe, rub
Pad abrasion condition.
Utility model content
For waste problem caused by more renewal of facing renewal in advance or have worn away caused by extreme position replaces not in time
Rivet is contacted with brake drum, thus the problem of scratching to brake drum, shortening the brake drum service life to influence braking ability, this is practical
It is novel to provide a kind of Pneumatic drum brake equipped with wear indicator.
The utility model uses following scheme:
The utility model include dust-break disc assembly, brake assembly, neck hoof assembly, from hoof assembly, be mounted on neck hoof assembly
On friction plate, the outer surface of friction plate forms rubbing surface, it is characterised in that: further includes alarm assembly, alarm assembly master
It to be successively linked in sequence and be formed by alarm inserted block, alarm electric wire and alarm wire terminal, friction plate inner surface is in neck hoof assembly mill
The marginal position processing for damaging most serious is fluted, and shape, the size of groove are identical as alarm inserted block, and the insertion of alarm inserted block is recessed
In slot, so that dust-break disc assembly exists outside the prominent brake assembly of the other parts in addition to alarm inserted block of alarm assembly
Position corresponding with friction plate groove is provided with peep hole, installation alarm device assembly from peep hole pass through after along brake shaft to
It is plugged in the groove of friction plate.
Preferably, alarm inserted block is semi-cylindrical structure, and the groove correspondence on friction plate is processed as special half slot.
Preferably, alarm inserted block is made of heat-resisting material.
The peep hole is sealed with peep hole plug, prevents dust sandstone from entering.
Alarm electric wire threading hole is equipped with inside the alarm inserted block.
The beneficial effects of the utility model are:
1) the utility model principle structure is simple, replaces the observation on original observation dust blocking tray using electronic type alarm principle
Hole confirms whether friction plate may wear to extreme position, and alarm in time, reduces artificial regular check number.
2) it can be accurately detected whether friction plate may wear to extreme position, precision is more accurate.
Detailed description of the invention
Fig. 1 is the Pneumatic drum brake structural figure equipped with wear indicator.
Fig. 2 is friction plate structure figure.
Fig. 3 is alarm assembly structure chart.
Fig. 4 is alarm assembly scheme of installation.
In figure: 10. brake assemblies, 11. neck hoof assemblies, 12. friction plates, 20. dust-break disc assemblies, 21. observation stopples,
30. alarm assembly, 31. alarm inserted blocks, 32. alarm electric wires, 33. alarm wire terminals.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, the utility model includes dust-break disc assembly 20, brake assembly 10, leads hoof assembly 11, is total from hoof
At, the friction plate 12 that is mounted on neck hoof assembly 11, the outer surface of friction plate 12 forms rubbing surface, as shown in figure 3, this is practical new
Type further includes alarm assembly 30, and alarm assembly 30 is mainly by alarm inserted block 31, alarm electric wire 32 and alarm wire terminal 33
Successively be linked in sequence composition, and 12 inner surface of friction plate is fluted in the marginal position processing that neck hoof assembly 11 wears most serious, recessed
Shape, the size of slot are identical as alarm inserted block 31, and alarm inserted block 31 is inserted into groove, so that alarm assembly 30 removes report
Outside the prominent brake assembly 10 of other parts except alert device inserted block 31, dust-break disc assembly 20 is corresponding with alarm assembly 30
Prominent position is provided with peep hole, installation alarm device assembly 30 from peep hole pass through after along brake shaft to being plugged in friction plate
In 12 groove, the peep hole observation stopple 21 of dust-break disc assembly 20 is sealed, and prevents dust sandstone from entering.
As shown in Figure 2 and Figure 3, alarm inserted block 31 is semi-cylindrical structure, and the groove correspondence on friction plate 12 is processed as spy
Different semi-cylindrical slot, semi-cylindrical slot compression moulding together with inner arc in friction plate manufacturing process, is not required to other processing sides
Formula, production is simple, while can prevent stress concentration from friction plate being caused to be broken.
As shown in figure 4, the installation principle process of the utility model are as follows: alarm inserted block 31 is inserted into 12 half slot of friction plate
It is interior, it is fixed on neck hoof hoof assembly 11, does not fall off alarm assembly when driving a vehicle abrasion.31 semicircle upper end shape of alarm inserted block
At worn area, the position of aperture is just taken in friction disc wear instruction on alarm inserted block 31, after assembly, in alarm
31 semicircle upper end of inserted block forms worn area, and 31 aperture height of alarm inserted block is friction plate limiting wear size.
In specific implementation, alarm inserted block 31 is made of heat-resisting material.
Alarm electric wire threading hole is equipped in specific implementation, inside alarm inserted block 31, for electric wire threading of alarming, alarm electricity
Line 32 passes through threading hole and connect with alarm inserted block 31, and the other end of alarm electric wire 32 is connect with alarm connector 33, alarming line
Connector 33 is suitable for current vehicle plug-in unit using the AMP C-282104 connector female connector of standard.
The course of work of the utility model is as follows:
In driving conditions, when automobile brake friction piece is constantly worn, when friction disc wear is to extreme position, i.e., mill will have been ground
Damage band before this wore the alarm electric wire 32 of 31 upper end of alarm inserted block as shown in 12 lateral projection of Fig. 2 friction plate, from
And form off state.Since alarm wire terminal 33 is directly connect with automobile instrument panel, alarm electric wire 32 reaches alarm signal
Alarm wire terminal 33 is connected to vehicle, alarms.Alarm signal reaches on bridge instrumentation disk, reminds driver, driver
Alarm signal is seen on automobile instrument panel, can quickly understand friction plate replacing construction, and Brake shoe lining has worn away to the limit
Position should be replaced in time, in order to avoid rivet is caused to contact with brake drum, scratch to brake drum, shorten the brake drum service life, influence to brake
Performance.
