Description
Technical field
The invention belongs to automobile equipment technical field, and in particular to a kind of car brake chamber vibration test frock and experiment
Method.
Background technology
With attention of the people to awareness of safety, and the braking ability of car is a key for determining automobile reliability energy
One of factor a, important spare part of the brake chamber as braking system, its performance is self-evident to the importance of vehicle, when
When car is braked, 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, presses to brake drum by Brake shoe lining and produces braking.
At present, brake chamber performance test project is in leakproofness, release pressure and loose pressure, static characteristic, low temperature seal
The comparative maturity that property, low-temperature working characteristic, compressive resistance, corrosion resistance etc. have been done, but due to shaking in terms of vibration-resistant property
It is that the limitation of the factors such as dynamic test platform, test tool, experimental condition is done at present and immature, can not complete detection go out brake chamber
Service life under real roads Vibration Condition, therefore be highly desirable design one kind and meet that brake chamber vibrates feelings in real roads
Rational test method and frock under condition.
The content of the invention
The purpose of the invention is to overcome the deficiencies in the prior art, and offer one kind is rational in infrastructure, experiment is accurate, manufacture
Cost low car brake chamber vibration test frock and test method.
The object of the present invention is achieved like this：A kind of car brake chamber vibration test frock, it includes electric vibrating
Testing stand, has been bolted test tool level board, the experiment on the upper side of the electric vibration testing bench
Test tool vertical plate and test tool reinforcing rib are connected on the upper side of frock level plate, the test tool erects
Straight panel and test tool reinforcing rib vertical connection, are connected with air chamber support, the gas on the medial surface of test tool vertical plate
Brake chamber has been bolted in room stent.
The test tool level board is strengthened with test tool vertical plate and test tool respectively by welding
Muscle connects.
The test tool vertical plate is connected with test tool reinforcing rib and air chamber support respectively by welding.
The quantity of the test tool reinforcing rib is 2, and is symmetrically arranged at the both sides of test tool vertical plate.
A kind of car brake chamber vibration testing method, brake chamber is fixedly connected with air chamber support using bolt,
Air chamber support is fixed on test tool vertical plate, and test tool level board makes to be fixed by bolts on electric vibration testing bench,
Gather real roads spectrum：The vibration test load modal data of power with frequency change is made, and is entered into electric vibrating examination
Test in bench control system, by setting control system to ensure that vibration processes can reproduce true road conditions；Arranged on test tool
Acceleration transducer, monitors vibration processes in real time by the data of feedback.
Beneficial effects of the present invention：Make brake chamber and air chamber support according to the true of collection using electric vibration testing bench
Road spectrum is vibrated, can Vibration Condition of the more real simulating brake gas chamber on vehicle；Reserve on test tool top
Space, through hole can be stamped according to air chamber support bolt hole position on test tool, meet different brake chamber vibration examinations
Test demand；Test tool adds part for simple welding, machine, and stock is fairly simple, and frock required precision is relatively low, processes, is manufactured into
This is cheap.
Brief description of the drawings
Fig. 1 is the structural representation of the test tool of a kind of car brake chamber vibration test frock of the present invention and test method
Figure.
In figure：1st, electric vibration testing bench 2, test tool level board 3, test tool vertical plate 4, test tool add
Strengthening tendons 5, air chamber support 6, brake chamber.
