Description
Technical field
The invention belongs to leaf spring detection technique field, particularly relate to a kind of leaf spring bearing up-down force bench test device.
Background technology
Leaf spring (abbreviation leaf spring) can be longitudinal or horizontal on automobile.Transverse spring is because of longitudinal direction to be transmitted
Power, it is necessary to arrange additional guiding load transfer device, makes that structure is complicated, quality strengthens, so only should in, minicar light in minority
With.Longitudinal leaf spring can transmit various power and moment, has guide function, and simple in construction, therefore obtains wide on automobile
General application.
Longitudinal leaf spring have again symmetrical expression and asymmetric formula point.In the middle part of leaf spring in fixing on axletree (bridge)
The heart (bolt is centre bolt herein) if the distance between grasswort center, leaf spring two ends is equal, is then symmetrical expression steel plate bullet
Spring；If unequal, the most asymmetric formula leaf spring.In most cases automobile uses symmetrical expression leaf spring.Due to car load
Reason in layout, or the installation site that leaf spring is on automobile is motionless, changes wheelbase again or by change wheelbase
When reaching the purpose improving axle load distribution, or in order to reduce the longitrorse that leaf spring produces when vehicle is in braking, sometimes adopt
With asymmetric formula leaf spring.Meanwhile, leaf spring also has multiple-leaf spring and lacks dividing of leaf spring, and single-leaf spring cross section also has
Cross section and variable cross-section point, every cross section of multiple-leaf spring is substantially uiform section, and every cross section of few leaf spring is to become to cut mostly
Face.
It is that automobile produces that the force-bearing situation of the leaf spring in the motion of simulating vehicle and motor process carries out bench test to leaf spring
Effective and the method for science in product development process.Vehicle mainly receives the effect exerted oneself in motor process, leaf spring
Bearing up-down force bench test is the basic and important bench test of leaf spring, the most only makees bearing up-down force stand with front plate spring,
And bench test is fairly simple, performance test and reliability test project are little, and test method also requires not mate with car load,
Can not fully hold characteristic and the life-span of leaf spring.It is difficult to again be fully understood from designed leaf spring when of short duration complete vehicle test
Performance, also has little time change design even if pinpointing the problems.
Leaf spring in automotive suspension is directly related to automobile bearing capacity, comfortableness, safety and operation stabilization
Property important spare part, along with the kind of exploitation vehicle gets more and more, the form of leaf spring is more and more various and complicated, vapour
The requirement of the precision of car research and development of products is more and more higher, and the requirement to the bench test of auto parts and components is more and more higher.Therefore,
Substantial amounts of bench test must be carried out and complete vehicle test could design the leaf spring meeting vehicle performance and reliability requirement, with
Time, bench test equipment and test method to leaf spring require more and more higher.
It is illustrated in figure 1 the bearing up-down force bench test device of existing leaf spring, is by leaf spring 02 by bearing pin
The grasswort at two ends is fixed on dolly 01, then pressing element 03 is put on leaf spring 02, applies test force F on pressing element 03,
Carry out detection and the endurancing of leaf spring 02 rigidity.Existing bench test device poor stability in process of the test；Can be real
The pilot project executed is few, can only carry out stiffness excitations and simple fatigue test, and test error is the biggest；Hydraulic cylinder is to steel plate
Pressing element on spring self is acted on by counteracting force while applying test force, due to the counteracting force shakiness to equipment
Fixed, big on impact equipment life；During fatigue test, dolly bearing capacity is limited, it is easy to damage；Test method is simple, with leaf spring
Actual loading and motion difference are bigger.
