Description
Technical field
The utility model relates to lower tie-rods, more particularly to a kind of damper mechanism of included bump leveller.
Background technique
Lower tie-rod is the antitorque component of pendulum model three-point suspension system, can the vibration of effective attenuation power assembly to interior biography
It passs, while being also the important path of vibration and noise transmitting.In complicated vehicle multisystem matching, some component mould if it exists
State is coupled with Engine Excitation frequency, will be generated resonance, is led to interior cavity noise, driver and passenger will perceive significantly
Rumbling sound substantially reduces the comfort of vehicle.The prior art is to solve resonate caused Vehicular vibration and noise problem, often
By testing approach, resonant component is found, general optimization is opened up by the structure more taken turns, changes the structure of resonant component, this way
The strength and stiffness loss that frequently can lead to vehicle key structure part, reduces the security performance of vehicle.Sometimes, there are multiple zero
Component resonance, resonance and noise problem can not be still solved by structure optimization, are wasted a large amount of design and manufacture expense, can not still be looked for
To effective solution approach, the delay of vehicle development node is also resulted in.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of vibration damping of novel included bump leveller
Mechanism.
The utility model is to solve above-mentioned technical problem by following technical proposals:
The utility model provides a kind of damper mechanism of included bump leveller, it is characterized in that comprising it is opened in antitorque drawing
Notch in the connecting rod of bar is provided with metallic gauge block, the top of the metallic gauge block and notch inner wall in the notch
Top between be fixed at least two spaced rubber sections, the bottom end of the metallic gauge block and the bottom end of notch inner wall
Between be fixed at least two spaced rubber sections, in the connecting rod and be located on the outside of the left and right end of notch and open up
There is through-hole, fender rod wears metallic gauge block and the both ends of fender rod are respectively placed in the side through hole of left and right.
Preferably, the rubber section is vulcanized rubber.
Preferably, the metallic gauge block is cast steel quality block.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with
Good example.
The positive effect of the utility model is:
The utility model is the bump leveller structure of included adjustable frequency, can be adjusted according to the particular problem of exploitation vehicle
The rubber structure of bump leveller, the weight of hardness and metallic gauge block develop vehicle for solving to realize specific frequency and damping
The resonance problem of type frequency promotes vehicle and drives quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the damper mechanism of the included bump leveller of the utility model preferred embodiment.
Fig. 2 is the perspective view of the damper mechanism of the included bump leveller of the utility model preferred embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As depicted in figs. 1 and 2, the present embodiment provides a kind of damper mechanisms of included bump leveller comprising is opened in antitorque
Notch 2 in the connecting rod 1 of pull rod, is provided with metallic gauge block 3 in the notch 2, the top of the metallic gauge block 3 and lacks
It is fixed between the top of 2 inner walls of mouth that there are two spaced rubber section, i.e. the first rubber section 4 and the second rubber section 5, the gold
Belong to and is fixed at least two spaced rubber sections, i.e. third rubber between the bottom end of 2 inner wall of bottom end and notch of mass block 3
Portion 6 and the 4th rubber section 7 in the connecting rod 1 and are located on the outside of the left and right end of notch 2 and offer through-hole 8, fender rod 9
The both ends for wearing metallic gauge block 3 and fender rod 9 are respectively placed in left and right side through hole 8.
Wherein, the rubber section is vulcanized rubber, and the metallic gauge block 3 is cast steel quality block.
By adjust the first rubber section 4, the second rubber section 5, the structure and hardness of third rubber section 6 and the 4th rubber section 7,
The weight of metallic gauge block 3 is adjusted to adjust resonant frequency and bandwidth.
Pass through absorbing mechanism of the design one with source of resonant excitation opposite direction, the suction on the necessary transmission path of vibration and noise
The source of resonant excitation is found without expending a large amount of resource by vibration mechanism, as long as the Frequency point of identification resonance, so that it may by adjusting rubber section
Rigidity, damping and quality adjust absorbing frequency in resonant belt, at the same direction of vibration on the contrary, can effectively eliminate resonance with
And its noise generated.This design can effectively avoid the change to vehicle key safety component, improve the safety of vehicle.
The absorbing mechanism does not need additionally to increase part, it is only necessary to vulcanize on existing Anti-torque pull rod according to identical technique
One bump leveller.Simple process, it is easy to adjust, manufacture and general assembly assembly efficiency can be greatly promoted.And the Anti-torque pull rod zero
Part is small in size, light-weight, can be relatively light with this matched bump leveller weight.
The vibration absorbing structure carries safety and Protection, even if bump leveller fracture failure, still can guarantee the safe operation of vehicle,
And security risk will not be generated to the rear end vehicle run at high speed, safety is good.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the protection scope of the utility model.
