Description
Technical field
The present invention relates to the on-line measuring devices and method of a kind of motor-car brake lining friction body thickness.
Background technique
Core component of the brake lining as motor vehicle brake system undertakes stationarity, the safety of train braking.Wherein friction piece
As the critical material of brake lining friction, abrasion, certain abrasion can be generated in each braking process, when friction body thickness is reduced to
When to a certain degree, brake lining just will appear failure, influence motor-car braking ability and operational safety.Motor train unit train operation is every about
It will do it daily level-one within 2 days to repair, full column brake lining appearance and friction piece residual thickness can be checked in maintenance process, to thickness
The brake lining for spending the requirement that reaches capacity is replaced.Since level-one is repaired, the time is short, and the brake lining quantity for needing to check is more, brake lining friction piece
Thickness checks on line.Currently, tool used in friction body thickness on-line measurement is mainly Steel Ruler or slide calliper rule, detection
When need in narrow and insufficient light maintenance tunnel, Steel Ruler or slide calliper rule are exactly perpendicularly to brake disc, there is labour
Intensity is big, inconvenient, low efficiency, the problems such as accuracy in detection is low and data are misread, and brake lining easily occurs transfinites military service or to mention
The phenomenon that preceding replacement.
Summary of the invention
The shortcomings that in order to overcome the prior art, the present invention provides a kind of on-line checking dresses of motor-car brake lining friction body thickness
It sets and method, on-line checking easy to operate, efficiently and accurately can be carried out to brake lining friction body thickness, overcome existing brake lining and rub
The defects of the inconvenient of rub body thickness detecting method, inefficiency and detection error.
The technical scheme adopted by the invention is that: a kind of on-line measuring device of motor-car brake lining friction body thickness, including T shape
Steel plate and the first detection faces being arranged on T steel plate, the second detection faces and detection datum level, wherein the second detection faces are to detecting
The height of datum level is H1, and the height of the first detection faces to detection datum level is H2, and H1 is greater than H2.
The present invention also provides a kind of online test methods of motor-car brake lining friction body thickness, it is characterised in that: including such as
Lower step:
Step 1: the detection datum level of cubing is fitted in brake disk surface；
Step 2: detect whether friction body thickness has more than needed with the second detection faces: if more than needed, terminating to exist to the brake lining
Ray examination；Conversely, then entering step three；
Step 3: whether wearing away limit with the first detection faces detection friction piece: if abrasion replace the brake lining to limit；
Conversely, the brake lining is then classified as recent key monitoring object.
Compared with prior art, the positive effect of the present invention is:
The present invention will need key monitoring and abrasion to be set as leading to the friction piece size limited, not-go-end size, and can root
According to the rank for needing key monitoring, logical, not-go-end size is subdivided, expands monitored size rate range.The present invention can it is convenient,
Efficiently and accurately on-line checking goes out to need key monitoring or abrasion to the brake lining friction piece of limit.
Detailed description of the invention
Examples of the present invention will be described by way of reference to the accompanying drawings, in which:
Fig. 1 is detection tool structure schematic diagram of the invention；
Fig. 2 is detection schematic diagram.
Specific embodiment
A kind of on-line measuring device of motor-car brake lining friction body thickness, as shown in Figure 1, comprising: the first detection faces 1, second
Detection faces 2, detection datum level 3, the first fillet 4, the second fillet 5, first cool down slot 6, second cool down slot 7 etc., in which:
Second detection faces 2 are the go side of cubing, and the height H1 of the second detection faces 2 to detection datum level 3 is brake lining friction piece
The size for needing key monitoring, having a size of 7-9mm；First detection faces 1 are the not-go-end of cubing, the first detection faces 1 to detection benchmark
The height H2 in face 3 is that brake lining friction piece is worn away to limit size, having a size of 5-7mm；First fillet 4 and the setting of the second fillet 5 are being examined
The both ends corner for surveying datum level 3 acts on to prevent cubing from scratching motor-car brake disc, having a size of R0.5-1mm；First cools down slot
6 and second cool down slot 7 be prevent detection when friction piece and cubing interference escape groove.
This cubing material uses carbon steel or tool steel, considers that the detection between motor-car brake clamp, brake lining, brake disc is empty
Between narrow and cubing portability, the profile arrangement of cubing is long 90-120mm, wide 10-30mm, high by 10-
15mm.Cubing first passes around wire cutting, processes T shape profile.Be heat-treated after wire cutting, guarantee the necessary rigidity of cubing and
Wearability.Each detection faces are gone out by fine grinding again, guarantee the first detection faces 1 and the second detection faces 2 to the ruler for detecting datum level 3
It is very little, and respectively detect surface roughness.The roughness of each detection faces should ensure that within Ra0.8, mainly prevent cubing from detecting
Brake disc and brake lining friction piece are damaged in journey.Finally, processing that each size requires will be met qualified cubing carry out deburring and
Cleaning.
The present invention also provides a kind of online test methods of motor-car brake lining friction body thickness, include the following steps:
Step 1: the detection datum level 3 of cubing is fitted in brake disk surface；
Step 2: detecting whether friction body thickness has more than needed with the second detection faces 2:
Second detection faces 2 are bonded brake lining friction piece (as shown in Figure 2): if the second detection faces 2 cannot be into judging the lock
Piece friction body thickness is more than needed, is not necessarily to key monitoring in the recent period；If the second detection faces 2 can be into carrying out step 3；
Step 3: whether wearing away limit with the first detection faces 1 detection friction piece:
First detection faces 1 are bonded brake lining friction piece (as shown in Figure 2): if the first detection faces 1 cannot be into judging the lock
Piece friction piece is soon worn away to limit, needs to carry out key monitoring to it in the recent period；If the first detection faces 1 can be into judging the brake lining
Friction piece is worn away to limit, needs to replace brake lining immediately.
Testing principle of the invention: the detection datum level 3 of cubing is bonded in brake disk surface, is detected respectively with cubing go side
Face 2 and not-go-end detection faces 1 are bonded brake lining friction piece (Fig. 2): detection faces 2 cannot be into expression brake lining friction body thickness is more than needed；Detection
It face 2 can be into detection faces 1 cannot be into expression brake lining friction piece is soon worn away to limit, needs key monitoring in the recent period；1 energy of detection faces
Into expression brake lining friction piece abrasion need replacing brake lining to limit.
