Description

Rubber vibration reduction suspension device

Technical Field

The utility model mainly relates to a car rubber damping technical field, concretely relates to rubber damping suspension device.

Background

With the rapid development of the automobile industry, consumers no longer meet rigid requirements such as automobile acceleration and engine power, and begin to pursue physical demands such as automobile comfort, comfort indexes are closely related to the NVH (Noise vibration and harshness) performance of automobiles, the engines are used as important excitation sources of the automobiles, and the vibration isolation performance of suspension systems has a very important influence on the NVH performance of the whole automobiles. The rigidity and the damping of the traditional structure rubber suspension are generally not changed in the use compression range basically, so that the vibration isolation performance is limited, the vibration isolation effect is only achieved in a certain frequency range, the adaptability is poor, the active and semi-active suspension vibration isolation performance is excellent, the price is high, the cost is high, only a few passenger vehicles are used, the commercial vehicles are hardly used, and the widely-applicable commercial requirements cannot be met.

Disclosure of Invention

The utility model aims at providing a rubber damping suspension device mainly comprises last skeleton, rubber, lower skeleton triplex. The upper end of the upper framework is fixedly connected with loads such as an engine, the lower end of the upper framework is connected with the upper surface of the rubber in a vulcanization mode, the lower end of the rubber is connected with the lower framework in a vulcanization mode, and the rubber can deform along with the load, so that the rigidity and the damping of the rubber are changed, the vibration is reduced, and the comfort of a vehicle is improved.

In order to achieve the above object, the utility model adopts the following technical scheme: a rubber damping suspension device is characterized in that: including last skeleton, rubber, lower skeleton, rubber includes first contact surface and second contact surface, rubber is trapezoidal structure for vertical cross-section, go up skeleton and rubber upper surface fixed connection, the rubber lower surface with skeleton fixed connection down.

Furthermore, the upper framework comprises a bolt, a first baffle plate and a second baffle plate, the vertical interface of the upper framework is in a shape of '2342458', the bolt is located in the middle of the upper framework and connected with an automobile firmware, and the first baffle plate and the second baffle plate are located on two sides of the upper framework.

Further, the first contact surface and the second contact surface are in a step shape or a plane shape.

Furthermore, the included angle beta between the first contact surface and the horizontal plane is larger than the included angle alpha between the first baffle plate and the horizontal plane

Furthermore, the lower framework is of a flat plate structure, and a first mounting hole and a second mounting hole which penetrate through the lower framework are formed in the two sides of the lower framework.

Compared with the prior art, the utility model discloses following profitable technological effect has:

reasonable structure, simple installation and good vibration damping performance. This vibration damper comprises the triplex, and the contact surface of rubber can design into ladder, plane or other shapes, compares bigger area of contact with traditional damping suspension, and rubber is along with the load increase and decrease, and its rigidity and damping also can change thereupon, improves the damping performance, goes up the produced vibration of skeleton joint load, weakens the vibration energy through rubber, and then transmits less vibration for the low side frame to improve the vehicle travelling comfort.

In the figure:

100. mounting a framework; 101. a bolt; 102. a first baffle plate; 103. a second baffle; 200 parts of rubber; 201. a first contact surface; 202. a second contact surface; 300. a lower framework; 301. a first mounting hole; 302. second mounting hole

Detailed Description

The above and further features of the present invention will be described in more detail below with reference to the accompanying drawings.

Example 1

A rubber-damped suspension device as shown in figure 1. The bolt 101 at the upper end of the upper framework 100 is fixedly connected with loads such as an automobile engine, and the like, and the first baffle plate 102 and the second baffle plate 103 are in a shape of a downward step with concave surfaces and are arranged outside the rubber 200 in a semi-surrounding shape. The upper part of the rubber 200 is in a step shape and is composed of a first contact surface 201 and a second contact surface 202, the upper surface area of the rubber 200 is smaller than the lower surface area, and the upper framework 100 and the lower framework 300 are made of metal materials and can be fixedly connected with the rubber 200 through a vulcanization process. When no load is applied, the first baffle plate 102 and the second baffle plate 103 are in a separated state from the first contact surface 201 and the second contact surface 202, when the bolt 101 is connected with a load such as an automobile engine, the first baffle plate 102 is in contact with the first contact surface 201, meanwhile, the second baffle plate 103 is in contact with the second contact surface 202, the contact surface is increased along with the increase of the load, the rigidity and the damping of the rubber 200 are increased along with the increase of the load, the vibration energy transmitted to the lower framework is greatly reduced, and the vibration damping effect is improved. Conversely, as the load decreases, the contact surface increases, the stiffness and damping of the rubber 200 decreases, the vibration energy transmitted to the lower frame decreases, and the vibration damping effect thereof also increases.
