Abstract
The utility model relates to a tunable frequency's rubber bump leveller, including vulcanizing stationary metal board, elastic element rubber layer and the installation metal sheet of connecting, still include two at least installation screw rods, the installation screw rod be fixed in elastic element rubber layer, still include the counter weight metal sheet, have and install the screw rod corresponding hole in position that the counter weight metal sheet can cup joint on the installation screw rod on the counter weight metal sheet, install the nut on the screw rod. The beneficial effects of the utility model are that, 1. Part simple to operate is installed at the vehicle to the shock absorber, and fixed mode is firm, 2. The frequency of operation of shock absorber debugs easily, 3. Resonance frequency can be discerned fast to bumper shock absorber installation development vehicle.
Description
Technical field
The utility model relates to the shock-absorbing means carrying out fast debugging identification in vehicle development process for resonance problem.
Background technique
Dynamic vibration absorber is a kind of vibration damping equipment by elastic element quality of assistance is connected in vibration system, its vibration attenuation mechanism is not carry out vibration damping by consumed energy, but by the dynamic action of quality of assistance, the power that elastic element is produced on the master system just in time with force the equal and opposite in direction of excitation force, direction contrary, reach the object of vibration damping with this.In the process of vehicle development, carrying out fast debugging and identification to resonance problem needs to apply bump leveller, and debugs the shock-absorbing means inconvenience very of corresponding frequencies.Existing rubber bump leveller is fixing not firm, particularly relates to the bump leveller of frequency-adjustable, and the balancing weight of increase is fixing can not meet measurement requirement, and it is accurate that impact is measured.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of convenient installation, the rubber dynamic vibration absorber of frequency-adjustable, can have good installation stability.
To achieve the above object of the invention, a kind of rubber bump leveller of frequency-adjustable is provided, comprise fixed metal plate, elastic element rubber layer and installation sheet metal that sulfuration connects, also comprise at least two and install screw rods, described installation screw rod is fixed on elastic element rubber layer; Also comprising Counter weight metal plate, Counter weight metal plate having the hole corresponding with installing screw position, Counter weight metal plate can be socketed in be installed on screw rod, and described screw rod installs nut.
Counter weight metal plate uses when needs regulating frequency, regulates the weight of bump leveller thus regulating frequency by superposition Counter weight metal plate.
Preferably, there is mounting hole described installation sheet metal bottom, and described mounting hole is tapped hole.
Preferably, hole is dodged in the middle of described elastic element rubber layer, fixed metal plate and Counter weight metal plate.
Preferably, described bore dia of dodging is greater than mounting hole diameter.
Preferably, at least 10 Counter weight metal plates identical in quality are comprised.
The rubber bump leveller of frequency-adjustable of the present utility model, have employed at least two and screw rod is installed, screw rod is installed for installing Counter weight metal plate, change the annexation of original Counter weight metal plate, the degrees of freedom of restriction Counter weight metal plate, make Counter weight metal plate not easily slide, come off, increase stability, make measurement more accurate.For increasing the soundness of rubber bump leveller integral installation, opening mounting hole in installation sheet metal bottom surface, can be bolted and be fixed, gluing more firm compared to existing technology.Hole of dodging in the middle of elastic element rubber layer, fixed metal plate and Counter weight metal plate is for coordinating vibration damper to install.
The beneficial effects of the utility model are, 1. vibration damper is easy for installation at vehicle mounting parts, and means of fixation is firm; 2. the frequency of okperation of vibration damper is easily debugged; 3. exploitation vehicle installed by vibration damper, can identify resonant frequency fast.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
According to the rubber bump leveller of a kind of frequency-adjustable described in Fig. 1 to Fig. 3, comprise and screw rod 1, fixed metal plate 4, elastic element rubber layer 5, installation sheet metal 6 and Counter weight metal plate 3 are installed.Fixed metal plate 4, elastic element rubber layer 5 and Counter weight metal plate 3 centre bit are equipped with dodges hole 2, dodges hole 2 for coordinating the mounting type of vibration damper.Install sheet metal 6 bottom and have mounting hole 7, mounting hole 7 is tapped hole, and installing sheet metal 6 can by installing in bottom surface adhesive means or being installed by bolt.Fixed metal plate 4 and install folder between sheet metal 6 and connect elastic element rubber layer 5 and three sulfides.Elastic element sulfuric horizon 5 is erect two installation screw rods 1, two installation screw rods 1 to be positioned in diametric(al).Counter weight metal plate 3 has two holes for being socketed on screw rod, carry out location and installation by being socketed in by Counter weight metal plate 3 to install on screw rod 1, double-screw structure has better stability.Dismantled and assembled Counter weight metal plate 3 is Spielpassung with installing screw rod 1, dismantled and assembled Counter weight metal plate 3 production quantity at least 10.Being connected with installation screw rod 1 by nut makes dismantled and assembled Counter weight metal plate 3 and fixed metal plate 4 be fixed and clamped, and adjusts the frequency of okperation of vibration damper by adjusting dismantled and assembled Counter weight metal plate 3.This design and installation screw rod 1 is at least two, controls dismantled and assembled Counter weight metal plate 3 and installs degrees of freedom, reach firm state; It is larger than mounting hole 7 that footpath, hole 2 is dodged in installation, is convenient to fitting operation.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
