The installation experiment demand of connection fork 17 of different size in brake chamber 1 can be met by changing transiting rod 14.This experimental rig is imitated
True degree is high, by setting rocker arm assembly and return component to simulate vehicle caused pivot angle A when actually braking, solves
Existing automobile brake chamber durability test device prevents existing result of the test from true because that can not simulate the pivot angle A
Reflect brake chamber quality and the reliability of work, the present invention can significantly shorten the R＆D cycle of brake chamber, significantly carry
High test efficiency and test effect, further improve product quality, have application value.
The technical scheme of existing automobile brake chamber durability test device is described in detail with reference to Fig. 2：
Existing automobile brake chamber durability simulation test apparatus, including existing bottom plate 29, an existing left side is housed on existing bottom plate 29
Riser 19 and existing right risers 22.Including brake chamber 1, brake chamber 1 is arranged on the existing outside of left risers 19, brake chamber 1
Including braking air chamber push rod 20, the front end of braking air chamber push rod 20 is equipped with existing transiting rod 21, and the other end of transiting rod 21 is mounted in existing
In right risers 22, existing returning device is housed in the outside of existing right risers 22, the existing returning device includes the first spring
Seat 23, return spring 24, support bar 25, caging bolt 26 and second spring seat 27, the first spring base 23 are fixedly mounted on existing
On the outside of right risers 22, support bar 25 is housed, the other end of support bar 25 is installed with second spring seat on first spring base 23
27, caging bolt 26 is housed on second spring seat 27, return spring 24 be sleeved on the first spring base 23 and second spring seat 27 it
Between, between the center line of braking air chamber push rod 20, the center line of transiting rod 21, the center line of return spring 24 and the center line of caging bolt 26
Collinearly, the inner side of link position is equipped with existing left boss 30 between existing left risers 19 and existing bottom plate 29, and an existing left side adds
Strong block 30 forms a fixed connection with existing bottom plate 29 and existing left risers 19 respectively.Existing right risers 22 and existing bottom plate 29 it
Between the outside of link position existing right boss 28 is housed, existing right boss 28 respectively with existing bottom plate 29 and existing left risers
19 form a fixed connection.
The operation principle of existing automobile brake chamber durability simulation test apparatus：During existing experimental rig work, return
Spring 24；Defined test pressure is passed through to the air inlet of brake chamber 1, braking air chamber push rod 20 is released, and promotes existing transiting rod
Moved after 21 until at the front end of caging bolt 26；After 1 air inlet air pressure of brake chamber is discharged, braking air chamber push rod 20 is in return
Return under the thrust of spring 24.
It can be seen that in the prior art, the movement locus of braking air chamber push rod 20 is straight line, i.e. braking air chamber push rod 20 is edge
The direction of axis line for existing transiting rod 21 is released by level, and therefore, it is produced when actually braking that it can not simulate vehicle
The pivot angle A, through existing durability test device carry out verification experimental verification brake chamber 1 can not reflect the real matter of product
Amount level and functional reliability.
The technical scheme of existing automobile brake chamber is described in detail with reference to Fig. 3,4, to be contrasted with the present invention,
So as to which beneficial effects of the present invention further can be clearly seen.
Brake chamber is also referred to as wheel cylinder, its act on be by the pressure transition of compressed air be make brake camshaft rotate machinery
Power, realize braking maneuver.Brake chamber is that clip clamps diaphragm type, and forward and backward brake chamber is of different sizes, but the basic phase of its structure
Together, it is by parts groups such as air inlet, lid, diaphragm, supporting disk, return spring, housing, push rod, connection fork, clamp and bolts
Into.When automobile brake, air enters brake chamber from air inlet, is deformed diaphragm under air pressure effect, promotes
Push rod, and braking adjusting arm is driven, rolling brake cam, Brake shoe lining is pressed into brake drum and produces braking.Diaphragm type
The brake force of air chamber push rod is directly proportional to input air pressure；Parking braking locellus is the brake apparatus deflated using spring energy-storage.Fill
Atmospheric pressure enters pressure air chamber by air inlet, acts the power on piston, when pressure is more than 0.65MPa, acts on work
The power of plug is more than the pretightning force of spring, piston stroking upward to the limit, brake release；If the gas of pressure locellus is vented completely, spring
Descent of piston is promoted, promotes main brake push rod to produce braking, severity of braking is relevant with initial tension of spring；When pressure air chamber, air pressure is low
When 0.65MPa, locellus produces brake force and is inversely proportional with atmospheric pressure value, therefore can implement emergency brake.
Fig. 3 show the actual initial entrucking position of brake chamber 1, the shaft hole of 17 front ends of the connection fork of brake chamber 1 with
The shaft hole of adjustment arm 32 upper end, which runs through the 3rd rotating shaft 31 in two shaft hole after freely aligning, forms hinge connection；Fig. 4
The operating position of brake chamber 1 is shown, now connection fork 17 is released, and promotes adjustment arm 32 certain with the center rotating of camshaft 33
Radius R, connection fork 17 rotates around the 3rd rotating shaft 31, and forms certain pivot angle A with the axial line of brake chamber 1.It can be seen that existing system
Room durability test device take offence when carrying out bench test, braking air chamber push rod 20 is along the existing axial line water of transiting rod 21
Square to motion, included angle A caused by the actual braking of vehicle, therefore existing endurance bench test device can not be simulated at all
The actual mass level and functional reliability of product can not truly be reflected.
