Abstract
The utility model relates to an antiskid absorber, which is composed of a wheel boss, a belt wheel inertia block, and a vibration isolating rubber ring arranged between the wheel boss and the belt wheel. The joints among the wheelboss, the rubber ring, and the belt wheel inertia block are provided with axial or radial pin holes, and elastic pin columns are arranged in the pin holes. The utility model is characterized in that the elastic pin columns are arranged among the wheel boss, the rubber ring, and the belt inertia block; the damping action of the absorber can be enhanced without affecting the effect of vibration isolating; the natural frequency is capable of satisfying the requirement of 350 +/-30HZ under the condition that the dynamic characteristics of the utility model is in the temperature of 25 DEG C.; the utility model is capable of preventing the slide or idle rotation of the belt wheel inertia block and increasing the service life and the reliability of the absorber.
Description
The utility model relates to a kind of vibration damper, particularly a kind of pressing type belt pulley vibration damper.
Widely used vibration damper is to be made of wheel hub, belt pulley inertial mass and the vibration isolation rubber circle that is positioned between the two in diesel engine for automobile.It is combined as a whole wheel hub and belt pulley inertial mass by the drive fit of the magnitude of interference of rubber ring.Because vibration damper is by friction driving, therefore big or be subjected to the influence that load moment increases and " coming unstuck " of occurring inertial mass easily skidded or dallied in load, thereby can not transmit required power, and its damping function is not strong, poor reliability, and working life is short.
The purpose of this utility model is to provide a kind of good damping result, reliability height, anti-skidding vibration damper that bearing capacity is strong.
The purpose of this utility model is achieved in that a kind of anti-skidding vibration damper, it is made of wheel hub, belt pulley inertial mass and the vibration isolation rubber circle that is positioned between the two, its special way is that the junction between wheel hub, rubber ring and belt pulley inertial mass three has axially or pin-and-hole radially, is provided with the elasticity pin in the hole.Junction between wheel hub, rubber ring, belt pulley inertial mass three is provided with the elasticity pin along circumferentially having two axially symmetrically arranged or pin-and-holes radially at least in the hole.On described pin-and-hole inwall, be provided with can prevent the resilient key axis of a cylinder to or the location tooth of radial-play.
Axial pin-and-hole of the present utility model is to be the center with the rubber ring, its aperture is greater than the thickness of rubber ring, promptly forming semicircle on wheel hub and belt pulley inertial mass respectively lacks, can remain between the two by pin like this and be closely as one, make this belt pulley inertial mass can not occur skidding, dallying.Pin-and-hole can be to connect vertically or do not connect.Radially pin-and-hole is to open to wheel hub from the belt pulley inertial mass, is through hole not.In order to keep the balance of vibration damper, need be symmetrical arranged two pin-and-holes at least, optimum scheme is three.In order to prevent the play of elasticity pin, on the pin-and-hole inwall, be provided with the location tooth, this location tooth can be the location tooth of shape of threads location tooth or corrugated location tooth or other structure.
Described pin is that elastic material is made, so the setting of pin not only can not influence effectiveness in vibration suppression, can also strengthen damping function, prevents that the belt pulley inertial mass from skidding or dallying.Pin can adopt rubber or polyurethane or other elastic material to make.The manufactured good pin can be fitted in the pin-and-hole or and cast in the pin-and-hole liquid semi-finished product elastic material.
Characteristics of the present utility model are: between wheel hub, rubber ring, belt pulley inertial mass the elasticity pin is set, when not influencing effectiveness in vibration suppression, can also strengthen the resistance of shock absorber effect, its dynamic characteristic is under 25 ℃ of situations, natural frequency satisfies 350 ± 30HZ requirement, and can prevent skidding or dallying of belt pulley inertial mass effectively, increase the working life and the reliability of vibration damper.It is simple in structure, manufactures easily.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of another embodiment of the utility model.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, vibration damper is the pressing type rubber shock absorber.Outside wheel hub (1), establish rubber ring (2) and belt pulley inertial mass (3) successively.At an end of vibration damper is wheel hub, rubber ring and triplicity place of belt pulley inertial mass along circumferentially being evenly distributed with three axial pin-and-holes that are center, its aperture greater than rubber ring thickness with the rubber ring, and axially pin-and-hole is through hole not, and hole depth is about 2c m.The pin-and-hole inwall is provided with shape of threads location tooth.The elasticity pin (4) that is arranged in the pin-and-hole is to adopt liquid polyurethane to cast in the hole.
As shown in Figure 2, this programme is along circumferentially having three equally distributed radially pin-and-holes at the vibration damper sidewall, radially the degree of depth of pin-and-hole should be from belt pulley inertial mass (3), rubber ring (2) to wheel hub (1), hole wall is provided with shape of threads location tooth, and elasticity pin (4) is to adopt the method identical with aforementioned schemes to cast in the pin-and-hole.
Claims (3)
1, a kind of anti-skidding vibration damper, it is made of wheel hub, belt pulley inertial mass and the vibration isolation rubber circle that is positioned between the two, it is characterized in that junction between wheel hub, rubber ring and belt pulley inertial mass three has axially or pin-and-hole radially, be provided with the elasticity pin in the hole.
2, anti-skidding vibration damper according to claim 1 is characterized in that junction between wheel hub, rubber ring, belt pulley inertial mass three along circumferentially having two axially symmetrically arranged or pin-and-holes radially at least, is provided with the elasticity pin in the hole.
3, according to claim 1,2 described anti-skidding vibration dampers, it is characterized in that on described pin-and-hole inwall, being provided with can prevent the resilient key axis of a cylinder to or the location tooth of radial-play.
