The present invention provides a double cushion vibration damping device, comprising a first bracket and a second bracket, a first cushion is arranged between the first bracket and the second bracket, a second cushion is arranged on the second bracket, and the second cushion is arranged on the second bracket. Gaskets are arranged on the second soft pad, and the first bracket, the first soft pad, the second bracket, the second soft pad and the gasket are sequentially fixedly connected by fixing bolts. The nut of the fixing bolt is arranged on one side of the first bracket, the base of the fixing bolt is arranged on the gasket, the first bracket is welded to the muffler hoop, and the second bracket is welded to the vehicle frame bracket. The invention realizes two-way vibration reduction in the vertical direction, reduces the influence of the vibration of the engine and the whole vehicle on the exhaust system, improves the reliability of the exhaust system, and reduces the influence of the vibration of the exhaust system on driving comfort.
Description
Technical field
The present invention relates to vehicle, engineering mechanical components, the definite exhaust system shock attenuation unit that says, is specifically related to a kind of two cushion shock attenuation units.
Background technology
Exhaust system is the important component part of automobile and construction machinery and equipment, in the course of the work owing to being subject to the vibration of driving engine and the vibration of car load, in order to guarantee the reliability of exhaust system work, conventionally adopt metal shock reducing flexible pipe and rubber mount to carry out vibration damping to exhaust system, make exhaust system offset the vibration being passed over by driving engine and car load.Traditional exhaust system shock attenuation unit, due to cushion unidirectional vibration damping in the vertical direction, the work of this supply and exhaust system brings risk.
Summary of the invention
For solving above technical matters, the invention provides a kind of two cushion shock attenuation unit, by increasing the mode of a cushion, realize the two-way vibration damping of vertical direction, reduce driving engine and car load and vibrated the impact on exhaust system.
The invention provides a kind of two cushion shock attenuation unit, comprise the first support and the second support, between described the first support and the second support, be provided with the first cushion, be provided with the second cushion on the second support, the first cushion and the second cushion alternately play damping of vibrations.On described the second cushion, be provided with pad, pad makes the second cushion upper surface stressed evenly, and described the first support, the first cushion, the second support, the second cushion and pad are fixedly connected sequentially by bolt of rear end plate.
The nut of described bolt of rear end plate is arranged on a side of the first support, and the base of described bolt of rear end plate is arranged on pad, and the predetermincd tension of bolt of rear end plate makes two cushions all have certain amount of compression.
Described the first support welding is in noise silencer hoop, and the second support welding is in frame brackets.
The invention has the advantages that simple in structure, easy to operate, be easy to produce, by increasing the mode of a cushion, make the first cushion and the second cushion replace vibration damping, realized the two-way vibration damping of vertical direction, reduced driving engine and car load and vibrated the impact on exhaust system, improve the reliability of exhaust system work, reduced exhaust system simultaneously and vibrated the impact on driver comfort.

The specific embodiment
Below in conjunction with Figure of description and specific embodiment, the present invention is described further:
As shown in the figure, the invention provides a kind of two cushion shock attenuation unit, comprise the first support 1 and the second support 2, between described the first support 1 and the second support 2, be provided with the first cushion 3, on described the second support 2, be provided with the second cushion 4, on described the second cushion 4, be provided with pad 5, described the first support 1, the first cushion 3, the second support 2, the second cushion 4 and pad 5 are fixedly connected sequentially by bolt of rear end plate 6.
In technique scheme, the nut of described bolt of rear end plate 6 is arranged on a side of the first support 1, and the base of described bolt of rear end plate 6 is arranged on pad 5.
In technique scheme, described the first support 1 is welded in noise silencer hoop 7, the second supports 2 and is welded in frame brackets 8.
Muffler assembly 9 is in the time of static state, and under the bearing force combined action of the gravity of the predetermincd tension of bolt of rear end plate 6, muffler assembly 9, frame brackets 8, the first cushion 3 and the second cushion 4 all have certain compressive deformation.Pad 5 makes the second cushion 4 upper surfaces stressed evenly.
When muffler assembly 9 upwards vibrates, the first cushion 3 is subject to the first support 1 vibration upwards, and pressure increases, and compressive deformation increases, the main damping of vibrations of the first 3 of cushions; When muffler assembly 9 vibration downwards, the second cushion 4 is subject to the downward vibration of pad 5, and pressure increases, and compressive deformation increases, the main damping of vibrations of the second 4 of cushions.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
The content not being described in detail in this specification sheets belongs to the known prior art of professional and technical personnel in the field.
