Description

A kind of vibration damping lifting type gearbox scaffold in parallel
Technical field
The utility model relates to gearbox mounting mechanism, particularly relates to a kind of vibration damping lifting type gearbox scaffold in parallel.
Background technique
Gearbox mainly refers to the gearbox of automobile, and it is divided into manual, automatic two kinds, and manual transmission, primarily of gear and axle composition, produces variable-speed torque-converting by different Gear combination; And automatic transmission case is made up of torque converter, planetary pinion and hydraulic control system, reach variable-speed torque-converting by the mode of fluid power transmission and Gear combination.Function is: one, change velocity ratio; Two, in the constant situation of hand engine rotation, automobile can be fallen back traveling; Three, utilize neutral, interrupt transmission of power, to start to enable motor, idling, and be convenient to shifting of transmission or carry out Power output.
Wherein torque converter is the parts of automatic transmission case most feature, and it is made up of components such as pump impeller, turbine and guide wheels, directly inputs engine power transmitting torque and clutch action.Pump impeller and turbine are a pair work combinations, and they are all right like two desk fans staggered relatively, and the wind-force of an active fans blowout can drive the blade rotary of another passive fan, the medium that the air of flowing--wind-force has become kinetic energy to transmit.If replace air to become the medium transmitting kinetic energy with liquid, pump impeller will drive turbine to rotate by liquid, then between pump impeller and turbine, adds upper block to improve the transmission efficiency of liquid.Because fluid torque converter automatic speed-changing and torque-converting scope is large not and efficiency is on the low side.
Gearbox is fixed by connecting frame when using.China Patent No. be 2011203696558, authorized announcement date be May 23 in 2012 day, be called that the patent document of " transmission auxiliary support assembly " discloses a kind of existing gearbox scaffold shortly.Its scaffold mainly comprising crossbeam and be connected to crossbeam.The deficiency that the performance that existing gearbox connecting frame exists vibration damping and noise reduction is low.
Model utility content
The utility model provides the good vibration damping lifting type gearbox scaffold in parallel of a kind of vibration isolating effect, solves the problem of existing gearbox scaffold vibration isolating effect difference.
Above technical problem is solved by following technical proposal: a kind of vibration damping lifting type gearbox scaffold in parallel, comprise crossbeam, be arranged at the link press span of crossbeam and base plate, the downside of described base plate is provided with supporting foot, the two ends of described crossbeam are all provided with strut, described strut slides and is arranged in described base plate, the lower end of described strut is provided with the damping rod being supported in described supporting foot, is provided with a pair elastomeric support column between described crossbeam and base plate.During use, the utility model carries out connecting with car body by supporting foot and realizes installing, and gearbox is connected to link press span.When the utility model is subject to the vibration of vehicle, vibrational energy deleted by damping rod, passes to horizontal vibration of beam and makes crossbeam produce resiliently deformable to enter and deleted, thus make the vibration passing to gearbox less.The setting of elastomeric support column, can extend working life and the antivibration effect of crossbeam.
As preferably, described damping rod is tubular structure, some dividing plates are provided with in described damping rod, the internal insulation of damping rod is gone out the cavity that some bearing of trends along damping rod distribute by described dividing plate, elastic diaphragm is provided with in described cavity, described cavity is divided into by described elastic diaphragm fills chamber and vacant chamber, described elastic diaphragm is the bowl shaped structure arched upward towards described filling chamber, quicksand is filled with in described filling chamber, increasing baffle-wall is provided with in described filling chamber, described filling chamber is divided into the first filling chamber and second and fills chamber by described increasing baffle-wall, described increasing baffle-wall is provided with connection first and fills the rubbing hole that chamber is filled in chamber and second, described vacant chamber is provided with the pore of through described damping rod.When producing vibration, damping rod produces distortion, damping rod distortion causes elastic diaphragm to flow back and forth between the first filling chamber and the second filling chamber towards motion, the meanwhile quicksand of the distortion of vacant chamber and reset, rub each other and consume vibrational energy during quicksand flowing, quicksand aggravates with the friction between rubbing hole friction and quicksand when flowing through rubbing hole, makes weakening energy-absorbing effect more remarkable.
As preferably, the outer circumferential face of described damping rod is provided with some outer deformation steering channels along damping rod axial distribution, the inner peripheral surface of described damping rod is provided with some along deformation steering channel in damping rod axial distribution, and described outer deformation guide slot and interior deformation guide slot are all the circular groove extended along the circumference of damping rod.Reliability when damping rod when being subject to vibrating drives quicksand to flow can be improved.
As preferably, described outer deformation guide slot and the alignment of interior deformation guide slot.Damping rod is made to have good shock attenuation result and rigidity.
The utility model has following advantage: vibration damping and energy-absorbing is effective, long service life.
