Preferably, described first ripple struction and described second ripple struction are triangle ripple.
Preferably, described first ripple struction and described second ripple struction are all arranged along the circumference of described inner cylinder liner.
Preferably, the primary peak of described first ripple struction is relative along the radial position of described inner cylinder liner with the second trough of described second ripple struction.
Preferably, the primary peak of described first ripple struction is positioned at the first arc surface, and the secondary peak of described second ripple struction is positioned at the second arc surface, and described first arc surface and described second arc surface leave gap.
Preferably, the described gap of two described hollow structures is unequal.
Preferably, the described hollow structure that described gap is less is also provided with the convex groove to described outer cylinder sheath near the side of described outer cylinder sheath.
Preferably, described hollow structure is through along the short transverse of vehicle.
Preferably, described hollow structure is curved slot arrangement.
Beneficial effect of the present invention is:
The present invention is by arranging hollow structure, and the first ripple struction and the second ripple struction are set at the inwall of hollow structure, when vibratory impulse is larger, original full inwall plane-plane contact is changed into part face or line face, the contact of some face, reduce impulsive force, thus play better buffer action, reduce abnormal sound, improve the traveling comfort of car load.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1, in a kind of detailed description of the invention, suspension swing arm bush structure provided by the present invention, comprise outer cylinder sheath 1, inner cylinder liner 3 and be connected the rubber bush 2 of outer cylinder sheath 1 and inner cylinder liner 3, rubber bush 2 is provided with hollow structure, and hollow structure is provided with two, and lays respectively at the both sides of the vehicle longitudinal axis, each hollow structure is provided with the first ripple struction 4 near the first inwall of outer cylinder sheath 1, and the second inwall near inner cylinder liner 3 is provided with the second ripple struction 5.
Above-described embodiment is by arranging hollow structure, and the first ripple struction 4 and the second ripple struction 5 is set at the inwall of hollow structure, when vibratory impulse is larger, the plane-plane contact of original full inwall is changed partial face contact or line face, the contact of some face, reduce impulsive force, thus play better buffer action, reduce abnormal sound, improve the traveling comfort of car load.
Usual outer cylinder sheath 1, inner cylinder liner 3 and rubber bush 2 integrated vulcanizing are shaping, to increase the reliability of whole lining.Certain three also separately after machine-shaping, can be assembled together, and can realize locking by elastic conjunction, or be connected by screw, bonding mode realizes locking.
First ripple struction 4 and the second ripple struction 5 are triangle ripple.Triangle ripple struction is simple, and when there is greater impact, the first ripple struction 4 contacts for some face or line face with the second ripple struction 5, reduces impulsive force further, buffering vibration.First ripple struction 4 and the second ripple struction 5 can one be only also triangle ripple, also can one or be square wave, arc ripple.
First ripple struction 4 and the second ripple struction 5 are all arranged along the circumference of inner cylinder liner 3, namely distribute along the primary peak of the first ripple struction 4 or the first trough along the circumference of inner cylinder liner 3; The secondary peak of the second ripple struction 5 or the second trough are along the axial distribution of inner cylinder liner 3.Because car load is mainly along the displacement of vehicle transverse axis and the swing around the vehicle longitudinal axis, can impact by buffering vibration better.
First ripple struction 4 and the second ripple struction 5 also can only one be arranged along the circumference of inner cylinder liner 3, also can one or both all arrange along the short transverse of vehicle.
The primary peak of the first ripple struction 4 is relative along the radial position of inner cylinder liner 3 with the second trough of the second ripple struction 5.This structure, when vibratory impulse, can be that primary peak inserts the second trough, and then buffering vibration impacts better.Also can primary peak relative along the radial position of inner cylinder liner 3 with secondary peak, also can primary peak between secondary peak and the second trough.
The primary peak of the first ripple struction 4 is positioned at the first arc surface, and the secondary peak of the second ripple struction 5 is positioned at the second arc surface, and the first arc surface and the second arc surface leave gap.Gap is set by the two, the elastic deformability of rubber bush 2 can be increased, and then buffering vibration impacts better.
The gap of two hollow structures is unequal.By the setting of different gap, improve different spacing, to adapt to the displacement along vehicle transverse axis in various degree and the beat along the vehicle longitudinal axis, buffering vibration impacts better.
The gap of two hollow structures also can be equal.
The less hollow structure in gap is also provided with the convex groove 6 to outer cylinder sheath 1 near the side of outer cylinder sheath 1.By arranging groove structure, the adaptation displacement along vehicle transverse axis in various degree and the beat along the vehicle longitudinal axis further, buffering vibration impacts better.
First arc surface also can overlap with the second arc surface.
First arc surface and the second arc surface are all coaxially arranged with inner cylinder liner 3.To facilitate processing, balanced vibratory impulse, improves whole suspension swing arm bush structure intensity.First arc surface and the second arc surface also can be arranged with inner cylinder liner 3 disalignment.
First arc surface of two hollow structures can lay respectively at different circumference, also can be positioned at identical circumference; Second arc surface can lay respectively at different circumference, also can be positioned at identical circumference.
Hollow structure is through along the short transverse of vehicle.This structure is convenient to processing, can increase the buffer capacity of rubber bush 2 further simultaneously.Hollow structure can be not through along the short transverse of vehicle yet.
Hollow structure is curved slot arrangement.This structure can prevent the stress of wedge angle from concentrating, and extends the service life of rubber bush 2.Hollow structure also can be rectangular groove structure or other is abnormally-structured.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
