Abstract
The utility model provides an automotive rear axle energy absorber and an automobile. The automotive rear axle energy absorber comprises a mass block (1), a rubber block (2) and a fixing piece (3), wherein the mass block (1), the rubber block (2) and the fixing piece (3) are fixedly connected in sequence, and the fixing piece (3) is fixedly connected with an axle housing of an automotive rear axle. The energy absorber is added to the automotive rear axle, so that the vibration of the automotive rear axle is transferred to the energy absorber, the vibration energy is converted into frictional heat to be consumed through the rubber block of the energy absorber, and the vibration and noise of the entire automobile are reduced at a normally used rotation speed. Besides, an original rear axle system is not changed, the arrangement and the functions of an underpan are not affected, and the comfort of automobile driving and taking is further improved.
Description
Technical field
The utility model relates to the vehicle arrangement technical field, is specifically related to a kind of automobile axle energy absorber and vehicle.
Background technology
Along with people are more and more higher to the traveling comfort requirement of automobile, the vibration noise characteristic of automobile also becomes more and more important.Particularly the SUV vehicle is when facing the relatively poor driving conditions of road conditions, and the preferably vibration noise absorption equipment driving that can significantly improve chaufeur is experienced.But the vibration noise absorption equipment of existing vehicle all is to arrange according to front-rear axle is unified, can not arrange separately according to concrete vehicle condition, causes the assimilation effect of vibration noise relatively poor.
The utility model content
The utility model provides a kind of automobile axle energy absorber and vehicle, can by shifting and consume the vibrational energy of back axle, reduce vibration and the noise of car load.
The utility model proposes following technical scheme:
The utility model embodiment provides a kind of automobile axle energy absorber, comprises mass, rubber block and connecting element;
Described mass, rubber block and connecting element are fixedly connected sequentially;
Described connecting element is captiveed joint with the axle housing of automobile axle.
Preferably, mass, rubber block and connecting element are captiveed joint by sulfuration.
Preferably, be provided with the screw that passes for bolt at connecting element, connecting element is captiveed joint with the axle housing of automobile axle by bolt.
The utility model embodiment also provides a kind of vehicle, and this vehicle set has aforesaid automobile axle energy absorber.
The utility model provides a kind of automobile axle energy absorber and vehicle, by increasing energy absorber at back axle, the vibration of back axle is transferred on the energy absorber, and the rubber block by energy absorber is converted to frictional heat energy with vibrational energy and consumes, thereby reduce vibration and the noise of car load under normal revolution, and do not change original rear bridge system, can not affect the chassis yet and arrange and function, and then improve the traveling comfort of driving.
Description of drawings
The structural representation of the automobile axle energy absorber that Fig. 1 provides for the specific embodiment of the present utility model.
The specific embodiment
The specific embodiment of the present utility model provides a kind of automobile axle energy absorber, as shown in Figure 1, comprise mass 1, rubber block 2 and connecting element 3, mass 1, rubber block 2 and connecting element 3 are fixedly connected sequentially, and connecting element 3 is captiveed joint with the axle housing of automobile axle.
In the utility model one optional embodiment, mass 1, rubber block 2 and connecting element 3 are captiveed joint by the sulfuration method.
In the utility model one optional embodiment, offer the screw 4 that passes for the bolt (not shown in figure 1) at connecting element 3, connecting element 3 can be captiveed joint with the axle housing of automobile axle by bolt.
By to the vibration of chassis system and the test analysis of internal car noise, this specific embodiment obtains under a certain normal revolution (for example 1400rpm), and the vibration noise of car load mainly is that the resonance by back axle causes.Therefore, by increasing energy absorber at back axle, the vibration of back axle is transferred on the energy absorber, and the rubber block by energy absorber is converted to frictional heat energy with vibrational energy and consumes, thereby reduce vibration and the noise of car load under normal revolution, improve the traveling comfort of driving.
The principle of work of the automobile axle energy absorber that this specific embodiment provides is: mass 1 is for energy absorber provides mass M, and rubber block 2 provides rigidity and damping for energy absorber.Weight by adjusting mass 1 and the hardness (rigidity and damping) of rubber block 2, the frequency the when model frequency of energy absorber is resonated with back axle is consistent.Behind the automobile axle energy absorber that adopts this specific embodiment to provide, by measuring the car load vibration noise, vibration and noise peak near the original normal revolution are disappeared, and will shake and noise is transferred near the lower rotating speed that is of little use, and amplitude also there is obvious reduction.Therefore, by the automobile axle energy absorber, particularly SUV vehicle that this specific embodiment provides, can reach and shift and consume the back axle resonance energy, reduce the purpose of car load vibration and noise.
The specific embodiment of the present utility model also provides a kind of vehicle, and described vehicle set has aforesaid automobile axle energy absorber, and the 26S Proteasome Structure and Function of corresponding each several part device is described in detail in the above-described embodiments, no longer applies at this and states.
The technical scheme that adopts this specific embodiment to provide, by increasing energy absorber at back axle, the vibration of back axle is transferred on the energy absorber, and the rubber block by energy absorber is converted to frictional heat energy with vibrational energy and consumes, thereby reduce vibration and the noise of car load under normal revolution, and do not change original rear bridge system, can not affect the chassis yet and arrange and function, and then improve the traveling comfort of driving.
The above only is embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
