Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of snubber block, achieve the installation of follow-up vibration damper preferably, effectively prevent the wearing and tearing that yielding rubber in use occurs simultaneously, the extrusion damage of yielding rubber is caused when transshipping, ensure that damping effect, invention also provides a kind of shock absorber structure.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of snubber block, it comprises neck bush, it is characterized in that: outside described neck bush, be set with external bushing, described external bushing comprises neck, supporting portion and axial extension part, between described neck bush and described external bushing, upper has yielding rubber, forms support end and part mounting end, the described yielding rubber of described axial extension part section arranges the first groove.
It is further characterized in that: the described yielding rubber of described neck section is provided with the second groove; Described support end comprises projection; Described protruding lower end is provided with the 3rd groove; Described projection is provided with the 4th groove; Described yielding rubber forms raised ribs in described neck lower end; Described neck bush length is less than described snubber block height; Described yielding rubber is coated on described external bushing;
A kind of shock absorber structure, it comprises two described snubber blocks, and two described snubber blocks are connected by screw bolt and nut.
In said structure of the present invention, between neck bush and external bushing, upper has yielding rubber, form support end and part mounting end, the yielding rubber of axial extension part section arranges the first groove, to be formed by support end with other connected elements and support, yielding rubber on support end creates the effect of damping, owing to being rationally provided with external bushing, in the installation of follow-up vibration damper, parts to be connected are connected with shock absorber rigidity, it is installed simple, effectively prevent the wearing and tearing that yielding rubber in use occurs and the extrusion damage causing yielding rubber when transshipping simultaneously.
Accompanying drawing explanation
Fig. 1 is the main sectional view of existing snubber block;
Fig. 2 is the main sectional view of snubber block of the present invention;
Fig. 3 is the plan view of Fig. 2;
Fig. 4 is vibration damper of the present invention and scheme of installation thereof.
Embodiment
See Fig. 2 and Fig. 3, a kind of snubber block, it comprises neck bush 1, neck bush 1 arranged outside external bushing 2, external bushing 2 comprises neck 2a, supporting portion 2b and axial extension part 2c, between neck bush 1 and external bushing 2, upper has yielding rubber 3, form support end 4 and part mounting end 5, yielding rubber 3 is coated on external bushing 2, the yielding rubber 3 of axial extension part 2c section arranges the first groove 6, the yielding rubber 3 of neck 2a section is provided with the second groove 7, the yielding rubber 3 of neck 2a lower end forms raised ribs 8, support end 4 comprises protruding 9, protruding 9 lower ends are provided with the 3rd groove 10, the 4th groove 11 is provided with on protruding 8.
Due to adding of external bushing:
(1), under overload and impact condition, can avoid product that excessive distortion occurs and the damage that causes, thus product be played to the effect of protection, extend its working life;
(2) direct wearing and tearing and the cutting of rubber part and client's machinery frame, is avoided.User does not need the manufacturing procedure too much considering mounting hole chamfering, thus reduces processing cost.
Second groove can reduce radial rigidity, makes the axial rigidity of product and the ratio of radial rigidity remain on about 1:1.This groove can also reduce at the stress having this region under vertical deviation condition, reduces the breakage of shock absorber part, increases the life-span.
Support end comprises projection, make support end stepped, when support end is stressed, form multistage support, ensure that support invariablenes pressure of liquid, the 3rd groove is a compression circular groove, when vibration damper works, this compression circular groove can increase holding time of linear elasticity coefficient, and the 4th groove prevents from and reduce stress concentrating, and increases the service life.
The yielding rubber of neck lower end forms raised ribs, and during installation, raised ribs is formed parts endoporus to be installed and supports, and is easier to the fitting operation of user, shortens the time that single-piece is installed, do not need user to increase the operations such as any chamfering on its mounting bracket, reduce costs.
Yielding rubber is coated on external bushing, and it can also prevent the corrosion of metalwork effectively, extends life of product.
In the present embodiment, neck bush length is less than snubber block height, forms rigid support, have impact on the support effect of snubber block when avoiding subsequent installation between neck bush.
See Fig. 4, a kind of shock absorber structure, it comprises two snubber blocks 12, 13, two snubber blocks are connected by bolt 14, snubber block is shown in Fig. 2, Fig. 3, it comprises neck bush 1, neck bush 1 arranged outside external bushing 2, external bushing 2 comprises neck 2a, supporting portion 2b and axial extension part 2c, between neck bush 1 and external bushing 2, upper has yielding rubber 3, form support end 4 and part mounting end 5, yielding rubber 3 is coated on external bushing 2, the yielding rubber 3 of axial extension part 2c section arranges the first groove 6, the yielding rubber 3 of neck 2a section is provided with the second groove 7, the yielding rubber 3 of neck 2a lower end forms raised ribs 8, support end 4 comprises protruding 9, protruding 9 lower ends are provided with the 3rd groove 10, the 4th groove 11 is provided with on protruding 8.
In the present embodiment, external bushing is metal external bushing; improve the support stiffness of external bushing; the qualified external bushing of pressure selection intensity that can certainly bear required for external bushing, as long as including passive external bushing in snubber block is all the scope of protection of the invention.
The design of above-mentioned special rubber profile of the present invention makes product possess larger linear rigidity scope, improves the effect of vibration isolation.
This structural design can control vehicle under less Oscillation Amplitude, the high dynamic vibrational loading of carrying.Well improve the comfort level under vehicle traveling, working state.
