Abstract
The utility model relates to a lowland slab bridge shell yawing force frock for fatigue test, the telescopic link of servo -cylinder is articulated with the connecting block, connecting block and loading frame fastening connection, reciprocal yawing force is applyed to loading frame to the servo -cylinder, loading frame upper portion inboard sets up left flange, fixedly connected with mount on the test bench, the mount inboard sets up right flange, left flange sets up with right flange relatively, treat about experimental lowland slab bridge shell both ends respectively with left flange, right flange joint. The utility model discloses a designing one and exerting the effort to lowland slab bridge shell from the side direction, realize the side direction load bench test of axle housing, the simulation passenger train axle housing lateral force circumstances in the journey that crosses of being expert at can as far as truly be reacted the yawing force and to the destruction of lowland slab bridge shell, overcome the not enough of present passenger car axle housing load test, provides safeguard for the safety traffic of low -floor vehicle.
Description
technical field:
The utility model relates to passenger vehicle axle loading test equipment technical field, is specifically related to a kind of low-floor axle housing side force torture test frock.
background technology:
Along with the fast development of China's bus industry and parts technology thereof, the requirement of market to bus safety also progressively improves.In passenger car axle R&D process, fatigue loading test is the important step ensureing passenger car axle application security, and when requiring this load test to simulate passenger vehicle actual motion as much as possible, the stress of axle housing, ensures the accuracy of load test structure as much as possible.
Traditional axle housing load test is mostly with reference to " QC/T533-1999 automobile drive axle Bench test methods " and " QC/T534-1999 automobile drive axle bench test evaluation index ", test method and the evaluation criterion of the vertical torture test of axle housing is defined in two standards, but, for low-floor vehicle bridge, in actual development process, the torture test of axle housing vertical curve is carried out by means of only " QC/T533-1999 automobile drive axle Bench test methods ", occur that bench test is passed through, and occurred the situation of the bridge hull to break down in road examination process.The analysis found that vehicle is in actual moving process, axle housing side force more easily causes the bridge hull to break down, at present, does not occur the torture test carried out for axle housing lateral force.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of low-floor axle housing side force torture test frock, it is that design energy applies acting force from side direction to low-floor axle housing, the side direction realizing axle housing loads bench test, simulation passenger vehicle axle housing lateral force situation in the process of moving, can as much as possible actual response side force to the destruction of low-floor axle housing, overcome the deficiency of existing passenger car axle load test, for the safety traffic of low-floor vehicle provides safeguard.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of low-floor axle housing side force torture test frock, wherein: comprise fixed mount, right flange, left flange, loading frame, contiguous block and servo-cylinder, expansion link and the contiguous block of described servo-cylinder are hinged, contiguous block and loading frame are fastenedly connected, servo-cylinder applies reciprocal side force to loading frame, loading frame upper inner arranges left flange, testing table is fixedly connected with fixed mount, right flange is set inside fixed mount, left flange and right flange are oppositely arranged, two ends, low-floor axle housing left and right to be tested respectively with left flange, right Flange joint.
Further, the expansion link of described servo-cylinder is connected by ball pivot with contiguous block.
Further, described servo-cylinder is hydraulic cylinder or for pneumatic cylinder or for actuator.
The beneficial effects of the utility model are:
1, the utility model is that design energy applies acting force from side direction to low-floor axle housing, the side direction realizing axle housing loads bench test, simulation passenger vehicle axle housing lateral force situation in the process of moving, can as much as possible actual response side force to the destruction of low-floor axle housing, overcome the deficiency of existing passenger car axle load test, for the safety traffic of low-floor vehicle provides safeguard.
2, the utility model structure simple, easy to use, conceive novel, with low cost, cost is low, simple and reliable, processing and fabricating is easy, overcome the deficiency of the simple vertical torture test of traditional axle housing, for passenger vehicle load test increases side force test, thus be the safety traffic increase guarantee of passenger vehicle, can effectively prevent faulty goods to come into the market, simultaneously also for technician provides test figure support.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is perspective view of the present utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, a kind of low-floor axle housing side force torture test frock, comprise fixed mount 2, right flange 3, left flange 4, loading frame 5, contiguous block 6 and servo-cylinder 7, described servo-cylinder 7 is hydraulic cylinder, expansion link and the contiguous block 6 of described servo-cylinder 7 are hinged by ball pivot, contiguous block 6 and loading frame 5 are fastenedly connected, servo-cylinder 7 applies reciprocal side force to loading frame 5, loading frame 5 upper inner arranges left flange 4, testing table 1 is fixedly connected with fixed mount 2, right flange 3 is set inside fixed mount 2, left flange 4 is oppositely arranged with right flange 3, low-floor axle housing about 8 two ends to be tested respectively with left flange 4, right flange 3 connects.
During test, the joint flange at low-floor axle housing about 8 two ends to be tested is fastenedly connected with left flange 4 and right flange 3 respectively, start servo-cylinder 7, servo-cylinder 7 applies reciprocating forces to contiguous block 6, and this acting force passes to low-floor axle housing by loading frame 5, the side force transmitted to axle housing by wheel in simulation bus driving process, servo-cylinder 7 constantly reciprocating action, side force constantly acts on low-floor axle housing, then detects the various performance of axle housing, realizes fatigue loading test.
After the utility model is connected with low-floor axle housing, in cantilever structure, tire earth point is simulated at the expansion link of servo-cylinder 7 and the connection center of contiguous block 6 ball-joint, thus realizes the bench test of axle housing side force fatigue.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
