The technical solution 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, equipped with existing on existing bottom plate 29
There are left risers 19 and existing right risers 22.Including brake chamber 1, brake chamber 1 is mounted on existing 19 outside of left risers, brakes gas
Room 1 includes braking air chamber push rod 20, and 20 front end of braking air chamber push rod is equipped with existing transiting rod 21, and 21 other end of transiting rod is mounted in existing
Have in right risers 22, in the outside of existing right risers 22 equipped with existing returning device, the existing returning device includes the first bullet
Spring abutment 23, return spring 24, supporting rod 25, caging bolt 26 and second spring seat 27, the first spring base 23 are fixedly mounted on existing
Have on 22 outside of right risers, second spring is installed with equipped with supporting rod 25,25 other end of supporting rod on the first spring base 23
Seat 27, equipped with caging bolt 26 on second spring seat 27, return spring 24 is sleeved on the first spring base 23 and second spring seat 27
Between, 20 center line of braking air chamber push rod, 21 center line of transiting rod, 24 center line of return spring and 26 center line of caging bolt it
Between it is conllinear, the inside of link position is equipped with existing left reinforcement block 30, an existing left side between existing left risers 19 and existing bottom plate 29
Reinforcement block 30 forms a fixed connection respectively with existing bottom plate 29 and existing left risers 19.In existing right risers 22 and existing bottom plate 29
Between link position outside equipped with existing right reinforcement block 28, existing right reinforcement block 28 respectively with existing bottom plate 29 and existing left vertical
Plate 19 forms 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 1 air inlet of brake chamber, braking air chamber push rod 20 is released, and promotes existing transiting rod
It is 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.
As 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, therefore, it is produced when actually braking can not to simulate vehicle
The pivot angle A, through existing durability test device carry out verification experimental verification brake chamber 1 cannot reflect the true matter of product
Amount level and functional reliability.
With reference to the technical solution of Fig. 3, the 4 existing automobile brake chambers of detailed description, to be carried out with the utility model
Comparison, so as to which the beneficial effects of the utility model further can be clearly seen.
Brake chamber is also referred to as wheel cylinder, and it by the pressure transition of compressed air is the machinery that rotates brake camshaft that effect, which is,
Power realizes braking maneuver.Brake chamber clamps diaphragm type for clip, and forward and backward brake chamber is of different sizes, but the basic phase of its structure
Together, by the parts group such as air inlet, lid, diaphragm, supporting disk, return spring, housing, push rod, connecting fork, clamp and bolt
Into.When automobile brake, air enters brake chamber from air inlet, is deformed diaphragm under air pressure effect, pushes
Push rod, and braking adjusting arm is driven, Brake shoe lining is pressed to brake drum and generates braking by rolling brake cam.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.It fills
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 pushed, main brake push rod is pushed to generate braking, severity of braking is related with initial tension of spring；When pressure air chamber's air pressure is low
When 0.65MPa, locellus generates brake force and is inversely proportional with atmospheric pressure value, therefore can implement emergency brake.
Fig. 3 show the practical initial entrucking position of brake chamber 1, the shaft hole of 1 connecting fork of brake chamber, 17 front end with
The shaft hole of 32 upper end of adjustment arm in two shaft hole by third shaft 31 freely to just forming hinge connection afterwards；Fig. 4
The operating position of brake chamber 1 is shown, connecting fork 17 is released at this time, pushes adjustment arm 32 certain with 33 center rotating of camshaft
Radius R, connecting fork 17 are rotated around third shaft 31, and form certain pivot angle A with 1 axial line of brake chamber.As 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 existing 21 axial line water of transiting rod
Square to movement, the included angle A generated during the practical braking of vehicle, therefore existing endurance bench test device can not be simulated at all
It can not really reflect the actual mass level and functional reliability of product.
