Abstract
The utility model discloses a kind of friction disc wear indicators, belong to engineering machinery accessories field.Including pin shaft and transit joint, it is communicating structure inside the transit joint, the pin shaft pass through transit joint inside and with transit joint clearance fit, the transit joint is equipped with the external screw thread connecting with wet type bridge external shell, and the end face on the right side of the pin shaft is set as fixed value X at a distance from the end face on the right side of transit joint.The utility model does not need disassembly assembly for being assemblied in wet type bridge, wet type bridge, so that it may measure the abrasion loss of internal friction plate, and then determine whether friction plate needs replacing, to improve the reliability of driving axis.
Description
Technical field
The utility model belongs to a kind of engineering machinery accessory, specifically, more particularly to a kind of friction disc wear indicator.
Background technique
The wet type bridge of country's wheel loader generallys use piston press friction plate and is braked at present, the abrasion of friction plate
Amount is the important indicator whether determining friction plate needs replacing.Since friction plate is assemblied in inside drive axle, abrasion loss is inconvenient
Measurement generally requires disassembly axle assembly and measures, and measurement process is taken a lot of work arduously.
Utility model content
The utility model aim is to provide a kind of friction disc wear indicator, is measured in drive axle in the prior art with overcoming
The abrasion loss of portion's friction plate, which needs to dismantle axle assembly and measures, causes measurement process to be taken a lot of work laborious defect.
The utility model adopts the following technical solutions realization:
The friction disc wear indicator, including pin shaft and transit joint, the transit joint inside is communicating structure,
The pin shaft pass through transit joint inside and with transit joint clearance fit, the transit joint be equipped with outside wet type bridge
The external screw thread of shell connection, the end face on the right side of the pin shaft are set as fixed value X at a distance from the end face on the right side of transit joint.
Preferably, the pin shaft is equipped with blind hole, is equipped with the pin being interference fitted with it in blind hole.
Preferably, the size of the fixed value X is 1.5mm.
It preferably, further include protective cover, the protective cover is threadedly coupled with transit joint.
Preferably, O-ring is equipped in the protective cover.
Compared with prior art, the utility model has the beneficial effects that
The utility model has many advantages, such as processing, assembles simple, practical convenient, is mainly used for loading machine wet type bridge, can also
For other engineering machinery, the wet type bridge for being assembled with friction disc wear indicator does not need disassembly assembly, so that it may measure inside
Friction plate abrasion loss, and then determine friction plate whether need replacing, to improve the reliability of driving axis.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the schematic diagram of the section structure of the utility model；
In figure: 1, selling；2, pin shaft；3, transit joint；4, O-ring；5, protective cover.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, friction disc wear indicator assembly described in the utility model includes pin 1, pin shaft 2, transition
Connector 3, O-ring 4, protective cover 5.
Pin shaft 2 is equipped with blind hole, and pin 1 is fitted in 2 blind hole of pin shaft, and pin 1 and pin shaft 2 are interference fit connection；Transition connects
First 3 inside is communicating structure, and pin shaft 2 passes through 3 inside of transit joint and connect with 3 clearance fit of transit joint, transit joint 3
It is equipped with the external screw thread connecting with wet type bridge external shell, 2 right end face of pin shaft is set at a distance from 3 right end face of transit joint
For fixed value X, X value is preferably 1.5mm；O-ring 4 is placed in protective cover 5, and protective cover 5 and transit joint 3 are connected through a screw thread.
The utility model friction disc wear indicator assembly is assembled to wet type by the external screw thread of transit joint 3 when installation
The designated mounting position of bridge external shell makes piston be in application position, protects at this time using maximum brake pressure pressing friction piece
Card, pin 1 withstand piston, and the distance between pin shaft 2 and the end face of transit joint 3 are X.
Working principle of the utility model is: with friction disc wear, it is right to transit joint 3 in the meeting of piston effect lower bearing pin 2
The axial movement of side end face side, and distance is gradually reduced, the end face on 2 right side of measurement pin shaft and 3 right end face of transit joint away from
From value, the difference i.e. abrasion loss of friction pair for the distance X that measured value and original state are set, distance value measurement can be with deeply
It spends ruler manual measurement to read, can also be measured with measurement sensor, measuring signal is sent to the screen of console by measurement sensor
It is directly displayed on curtain.After being assembled with friction disc wear indicator, disassembly assembly is not needed, so that it may measure internal friction plate
Abrasion loss, to determine whether friction plate needs replacing, to improve the reliability of driving axis.
