Abstract

The utility model discloses a vibration damper fatigue life and performance test stand for the adjustable eccentric crank shaft, whose crank eccentric adjustment mechanism comprises two combined eccentric wheels, and achieves the stepless adjustment of the excentricity of the crank through the corresponding rotation of the two eccentric wheels. The input shaft of the crank shaft transmission mechanism provides an eccentric base. An eccentric structure is between the center of the stop hole on the eccentric base used to fix the crank shaft and the center of the input connecting shaft. Simultaneously, the eccentric base is connected with a crank shaft. An eccentric structure is between the peripheral center of the crank shaft and the center of the output shaft used to drive the tested vibration damper to move. The crank shaft is positioned by the stop hole on the eccentric base and fixed by the screw bolts. The crank shaft rotates winding the center shaft line An of the stop hole on the eccentric base caused by unscrewing the fixing nuts on the screw bolts when the excentricity is adjusted. The excentricity, which is the center shaft line C of the output shaft used to drive the tested vibration damper to move corresponding to the center shaft line B of the input connecting shaft, is steplessly adjustable between 0-2e. The utility model, which is convenient to adjust, has the advantages that the structure is unique, simple, compact, reliable, etc.

Description

A kind of vibration damper fatigue lifetime and performance test stand of adjustable eccentric bent axle
Technical field
The utility model belongs to a kind of vibration testing device, belongs to a kind of test of mechanical part, is meant the test unit that the antifatigue and the performance of damper components are tested especially.Be mainly used in the fatigue lifetime and the performance test that detect oil-pressure vibration reducer for railway, also can be used to detect the vibration damper of other motor vehicles.
Background technology
At present, continuous development along with the modernization of industry, traffic is more and more convenient, the vehicles particularly vehicles of mechanization (motor vehicles) are also more and more, vibration damper is very important in the modern means of communication (motor vehicles) parts, it will be directly connected to the comfortableness and the stability of motor vehicles operations, so the vibration damper of motor vehicles all must carry out antifatigue and performance test when dispatching from the factory, and this test is normally carried out on a kind of special testing table.Owing to carry out antifatigue and performance test on testing table all is to realize by a vibrational system of simulating.And the vibrational system of existing this simulation often all is by change speed gear box of a driven by motor, drives an eccentric stiffener by change speed gear box through a pulley gear again and realizes what multifrequency vibration mode was tested.That tests is effective and bad, the very important point is exactly whether the adjustment of eccentric stiffener is flexible, and existing eccentric stiffener often be exactly to exist to adjust be not very flexible, a kind of structure comes to this as Chinese patent ZL95226272.X disclosed " a kind of testing table that is used for the ride-control performance test ".Two stand column and beam supports of its testing table are contained on the table top of support, and crossbeam connects two root posts, and can move up and down.The horizontal bearing of base inner, bearing axle one end is equipped with toggle, and the other end is equipped with motor-operated big belt pulley.Can carry out the vertical vibration test of product by toggle.But this toggle is not very flexible problem with regard to exist adjusting, and therefore test is got up and actual operating condition is still gap.Therefore necessary this is improved.
Summary of the invention
The purpose of this utility model is the deficiency at present various oil-pressure damper testing tables, proposes a kind of very flexible crank eccentric adjustment of adjusting when the vibration damper test run.So that the test condition of the actual operating mode of simulated maneuver vehicle can be provided more easily.So that can detect the performance of product really.
According to the technology implementation scheme that the purpose of this utility model proposed be: the vibration damper performance test stand is divided into drive unit and control test macro two parts.Drive unit comprises main motor, belt gear, crank axle gear train, and the crank eccentric adjustment.The function of drive unit is the cyclical movement that mounted thereto test vibration damper end is produced certain rule.The Dynamic Signal of vibration damper is picked up, amplifies, calculates, writes down and shown by the control test macro, and is controlled as the case may be by it.Its characteristics are: the crank eccentric adjustment is formed by two eccentric wheel combinations, and realize the electrodeless adjustment of the eccentricity of crank by two eccentric relative rotations, one eccentric mounting is arranged on the input shaft of crank axle gear train, be used for fixing on the eccentric mounting between the center of the center in seam hole of crank axle and input coupling shaft for eccentric structure, eccentric throw is e (e=5~30); Simultaneously, eccentric mounting links to each other with a crank axle, and the center of its outer rim and being used to drives between the center of output shaft of tested vibration damper motion and also is eccentric structure on the crank axle, and eccentric throw is e ' (e '=5~30), crank axle is with location, the seam hole on the eccentric mounting, with the bolt of 4 M20.When adjusting eccentric throw, unscrew the hold-down nut on the bolt of 4 M20, make the central axis A rotation in the seam hole of crank axle on eccentric mounting, the central axis C that is used to drive the output shaft of tested vibration damper motion on the crank axle is imported the eccentric throw of the central axis B of coupling shaft relatively can be electrodeless adjustable between 0~2e.
Characteristics such as the utility model takes the assembly of double eccentric wheel to adjust the eccentric throw of crank, has structure uniqueness, simple, compact, reliable, and is easy to adjust, employing is worthy to be popularized.
