Description
Technical field
The utility model relates to absorber technical field more particularly to a kind of centrifugation pendulum dampers.
Background technique
Traditional spring-mass bump leveller, which is chiefly used in weakening, exports caused twisting vibration by automobile engine.However, main
Disadvantage is wanted to be the acting frequency narrow range of spring-mass bump leveller.It must be in specific engines normal operating frequency range
The design of compromise spring bump leveller, leads to that effective damping can not be provided below intrinsic frequency.Therefore, target is in the industry
The scheme of identical damping property can be provided in the entire operating rotational speed range of engine by finding.
Centrifugation pendulum damper just has this characteristic, and the power source to swing back and forth is mentioned mainly by the centrifugal force of pendulum
For.In rotary shaft motion process, centrifugal force offsets the torque ripple of engine output, to farthest reduce the torsion of axis
Vibration.Since the intrinsic frequency of centrifugation pendulum damper is directly proportional with engine speed always, therefore the centrifugal pendulum under any revolving speed point
The frequency of oscillation of formula damper can match the driving frequency of the fixed order of engine.However, in the revolving speed model of slightly above idling
In enclosing, centrifugation pendulum damper centrifugal force is lower, needs to go to store genuine energy using swing angle as big as possible to be promoted
Anti-vibration performance.
Although the basic structure of centrifugation pendulum damper theoretically can reach expected vibration damping purpose at present, one kind is needed
Novel and improved centrifugation pendulum-type damper damping system, is presented good damping property simultaneously in all engine speed ranges
Meet the mass production application of Practical Project.

Detailed description of the invention
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, in which:
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the top view of the utility model embodiment；
Fig. 3 is the partial structural diagram of the utility model embodiment.
Specific embodiment
Referring to Fig. 1 to Fig. 3, a kind of centrifugation pendulum damper of the utility model, including at least one rotatable flange
Disk 1 and at least one be mounted on ring flange 1 and keep the dynamically balanced goods of furniture for display rather than for use 2 of ring flange 1, the goods of furniture for display rather than for use 2 and/or ring flange
Motion path 3 is provided on 1, the goods of furniture for display rather than for use 2 can be moved with respect to ring flange 1 along motion path 3, is provided on the goods of furniture for display rather than for use 2 slow
Rush block 22.In the present embodiment, it can be seen that the main function of goods of furniture for display rather than for use 2 is energy storage and the effect for balancing entire ring flange 1.
In order to further illustrate, several installation protrusions 11, goods of furniture for display rather than for use are provided on the outer of ring flange 1 described herein
2 both ends are mounted in adjacent installation protrusion 11, and motion path 3 is arranged on the both ends and/or installation protrusion 11 of goods of furniture for display rather than for use 2.
It is provided with the motion path 3 in the both ends of the goods of furniture for display rather than for use 2 and installation protrusion 11, can be simply interpreted as in 2 conduct of goods of furniture for display rather than for use
The part of entire ring flange 1 extends.In the present embodiment, goods of furniture for display rather than for use 2 is provided with multiple groups, and preferably four groups or five groups, equal distribution exists
On the outer of ring flange 1, so that dynamic balancing when entire ring flange 1 rotates.And the setting position restriction of motion path 3 pendulum
All motion profiles of part 2.
In order to guarantee that goods of furniture for display rather than for use 2 can automatically reset, the motion path 3 is the long lumbar hole of arc, and the goods of furniture for display rather than for use 2 passes through pin
4, which pass through motion path 3, is movably arranged in installation protrusion 11.The bending direction of motion path 3 and installation protrusion on the goods of furniture for display rather than for use 2
The bending direction of motion path 3 is opposite on 11.The design of such structure, when ring flange 1 rotates, goods of furniture for display rather than for use 2 because centrifugal force and
Opposite ring flange 1 moves, and the contradictory design person of the motion path 3 in the two makes when goods of furniture for display rather than for use 2 is moved by pin 4, fortune
Dynamic path 3 there is reaction force to carry out counteracting centrifugal force pin, and then achieve the purpose that energy storage.In addition, goods of furniture for display rather than for use 2 can also phase
The peripheral force for generating a rotation to ring flange 1 can also generate ring flange 1 centainly so that it is along 3 reciprocally swinging of motion path
Vibration, improve the Oscillation Amplitude of entire ring flange 1, reduce the centrifugal force of entire damper, and then reached vibration damping
Purpose.
Further, referring to figs. 2 and 3, the goods of furniture for display rather than for use 2 includes two pendulums 23 and mass block 21, two pendulums 23
The two sides of ring flange 1 are separately positioned on, the mass block 21 is arranged between two pendulums 23, and front and rear sides are separately connected two
The left and right sides of mass block 21 is arranged in a pendulum 23, the buffer stopper 22.Wherein, two pendulums 23 are riveted by rivet 5
On mass block 21, so that two pendulums 23 are connected with mass block 21, wherein mass block 21 is the middle part for being located at pendulum 23,
So that the center of gravity of entire goods of furniture for display rather than for use 2 is easy control, reduce the unstable of anaphase movement.
Further, the mass block 21 is triangular in shape, the center of rotation of one jiao of direction ring flange 1 of mass block 21；It is slow
Rush that block 22 is V-shaped, and holding is on the angle that mass block 21 is directed toward 1 center of rotation of ring flange.Since installation protrusion 11 is mounted in
It is at an angle between adjacent two installations protrusion 11 on the outer of ring flange 1, therefore, in the structure of mass block 21
Design is designed also for agreeing with this angle.Since mass block 21 can follow two pendulums 23 to move along motion path 3,
Mass block 21 can be collided with installation protrusion 11, in order to reduce the noise of this collision, therefore be obstructed using buffer stopper 22, real
Present engine closes or opens the sound for reducing collision in the case of air throttle when shutting down.
Goods of furniture for display rather than for use 2 is arranged in this damper on ring flange 1, carries out phase using the motion path 3 on goods of furniture for display rather than for use 2 or ring flange 1
The mutually movement of both limits, so that generated centrifugal force offsets the torque ripple of engine output in 2 rotation process of goods of furniture for display rather than for use, from
And farthest reduce the torsional oscillation of output shaft.Furthermore it is provided with buffer stopper 22 on goods of furniture for display rather than for use 2, reduces goods of furniture for display rather than for use 2 and moves phase
Shock to ring flange 1, reduces the vibration of rotation process, while increasing the stationarity of entire damper rotation.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, all should belong to the utility model
Protection scope.
