A verify test device of dust cover leakproofness, includes dust case, its characterized in that: gas blowing device is connected to the one end of dust case, and pulse pressurized equipment is connected to the other end of dust case, pulse pressurized equipment pass through tube coupling braking pincers, the bridge position of braking pincers is put and is connected spring assembly. It mainly is through the working process of simulation braking pincers under the adverse circumstances extremely to compare with prior art, provide a verify test device of dust cover leakproofness, verifies the dust cover sealed and dustproof effect under adverse circumstances for a long time.
Description
Technical field
The utility model is related to caliper technical field, specifically a kind of experiment dress for verifying dust cover sealing
Put.
Background technology
In caliper braking procedure, piston promotes inner attrition piece to compress brake disc, piston port in the presence of hydraulic coupling
Expose, after end of braking, piston return in the presence of sealing ring is return in caliper, it can be seen that caliper is by work
Plug is moved back and forth and realizes automobile brake.
It is water stain many because caliper working environment dust is more, in order to avoid dust, impurity and water stain by brake caliper piston
Pollution, brings impurity into during return, be mixed into brake fluid, influences the braking effect of caliper, piston even quilt when serious
It is stuck, cause brake failure.Therefore, in piston port and brake caliper cylinder mouthful one dust cover of design and installation, in connection piston
While with housing, and piston and caliper shell are adjacent to all the time, so as to reach dust-proof and sealing function.
However, the sealing quality of the dust cover, just directly means the braking effect of caliper；It is therefore desirable to test
Demonstrate,prove the sealing of the dust cover.
The content of the invention
The utility model is to overcome the deficiencies in the prior art, there is provided a kind of experimental rig of checking dust cover sealing, main
If clamping the course of work under extremely adverse circumstances by simulating brake, checking dust cover in the presence of a harsh environment close for a long time
Envelope and dustproof effect.
To achieve the above object, a kind of experimental rig for verifying dust cover sealing, including dust box are designed, its feature exists
In：One end connection blowning installation of dust box, the other end connection pulse-pressure equipment of dust box, described pulse-pressure equipment
Caliper, the bridge portion position connecting spring device of caliper are connected by pipeline.
The mixed liquor of dust and water is provided with described dust box, the bottom of dust box is equipped with pipe, and pipe is provided with
Some apertures.
Described dust box is in inverted trapezoidal structure, and the upper end open of dust box is more than dust box lower end base structure.
The pipe connection blowning installation of described dust box bottom, blowning installation is horizontal pipeline structure.
The utility model is compared with the existing technology, there is provided a kind of experimental rig for verifying dust cover sealing, mainly leads to
Cross the simulating brake course of work of the pincers under extremely adverse circumstances, checking dust cover sealing for a long time in the presence of a harsh environment and anti-
Dirt is acted on.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is dust box, and 2 is the mixed liquor of dust and water, and 3 is blowning installation, and 4 is pulse-pressure equipment, and 5 are
Spring assembly, 6 is caliper, and 7 is pipe.
Specific embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, one end connection blowning installation 3 of dust box 1, the other end connection pulse-pressure equipment of dust box 1
4, described pulse-pressure equipment 4 connects caliper 6 by pipeline, the bridge portion position connecting spring device 5 of caliper 6.
The mixed liquor 2 of dust and water is provided with dust box 1, the bottom of dust box 1 is equipped with pipe 7, if pipe 7 is provided with
Dry aperture.
Dust box 1 is in inverted trapezoidal structure, and the upper end open of dust box 1 is more than the lower end base structure of dust box 1.
The connection blowning installation 3 of pipe 7 of the bottom of dust box 1, blowning installation 3 is horizontal pipeline structure.
Dust box：Whole verification experimental verification place, there is provided caliper working environment, connection blowning installation and pulse-pressure set
It is standby.
Dust and water mixed liquid：Simulating brake pincers dust cover extremely harsh environments.
Blowning installation：Pipe with dust box bottom of which has holes is connected, there is provided compressed air, stirs dust and water mixed liquid,
Prevent dust from precipitating.
Pulse-pressure equipment：Air pressure is provided to caliper, brake caliper piston movement is promoted, real vehicle hydraulic braking is simulated, it is real
The existing caliper dust cover course of work.
Spring assembly：The reciprocating motion of brake caliper piston is realized, so as to drive dust cover to stretch and retract.Air pressure pressurizes
When, promote brake caliper piston to be moved to spring, spring is compressed, and dust cover can be stretched as piston is moved；When air pressure discharges,
Recoil of spring promotion brake caliper piston return, dust cover can shrink with piston return.
Caliper：Realize the course of work of caliper dust cover.
Specific test method：
1. the mixed liquor 2 of the dust of white and water is filled in dust box 1, is passed through by the way that blowning installation 3 is continual
In compressed air to dust box 1, compressed air is entered into can constantly discharge bubbling in the mixed liquor 2 of dust and water, stir powder
The mixed liquor 2 of dirt and water, prevents dust from precipitating.
2. caliper 6 is placed in dust box 1, and invades the mixed liquor 2 of dust and water completely, wherein caliper 6
It is a spring assembly 5 that friction plate and brake disc position change the outfit, and the meeting of spring assembly 5 is because of forced compression or opens.
3. starting impulse pressurized equipment 4, simulates real vehicle hydraulic braking.Brake caliper piston is promoted to be moved to spring when air pressure pressurizes
It is dynamic, spring is pressurized and is shunk；When air pressure discharges, spring resilience when not stressing produces reaction force, promotes brake caliper piston
Return；During air pressure pressurization and release, dust cover can be moved with piston and produce stretching, the motor pattern of contraction etc.,
Realize the course of work of caliper dust cover.
4. so circulation is pressurizeed and is discharged to air pressure, and dust cover is constantly stretched and shunk, through it is long when
Between experiment after, take out caliper, disassemble dust cover, check in dust cover whether there is white dust, checking in plunger shaft is
It is no to have white dust, so as to reach the purpose of checking dust cover sealing.
