Abstract
The utility model provides a double cushion 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, a gasket is arranged on the second cushion, and the first bracket, the first cushion, the second bracket, the second cushion and the gasket are sequentially and fixedly connected through fixing bolts. Nuts of the fixing bolts are arranged on one side of the first bracket, the base seat of the fixing bolts are arranged on the gasket, the first bracket is welded to a muffler hoop, and the second bracket is welded to a frame bracket. According to the double cushion damping device, two-way vibration reduction in vertical direction is achieved, the effect from an engine and a full vehicle vibration to an exhaust system is reduced, work reliability of the exhaust system is improved, and meanwhile the effect from the exhaust system vibration to driving comfort is reduced.
Description
Technical field
The utility model relates to vehicle, engineering mechanical components, and the definite exhaust system shock attenuation unit that says is specifically related to a kind of pair of cushion shock attenuation unit.
Background technology
Exhaust system is the important component part of automobile and construction machinery and equipment, in the course of the work owing to be subject to the vibration of driving engine and the vibration of car load, in order to guarantee the reliability of exhaust system work, usually adopt metal shock reducing flexible pipe and rubber mount that exhaust system is carried out vibration damping, make exhaust system offset the vibration that is passed over by driving engine and car load.Traditional exhaust system shock attenuation unit, because cushion unidirectional vibration damping in the vertical direction, the work of this supply and exhaust system brings risk.
The utility model content
For solving above technical matters, the utility model provides a kind of pair of cushion shock attenuation unit, by increasing the mode of a cushion, has realized the two-way vibration damping of vertical direction, has reduced the vibration of driving engine and car load to the impact of exhaust system.
The utility model provides a kind of pair of cushion shock attenuation unit, comprise the first support and the second support, be provided with the first cushion between described the first support and the second support, be provided with the second cushion on the second support, the first cushion and the second cushion alternately play damping of vibrations.Be provided with pad on described the second cushion, 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 the pad, and the predetermincd tension of bolt of rear end plate makes two cushions that certain amount of compression all be arranged.
Described the first support welding is in the noise silencer hoop, and the second support welding is in frame brackets.
The utility model has the advantage of 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 the vibration of driving engine and car load to the impact of exhaust system, improve the reliability of exhaust system work, reduced simultaneously the impact of exhaust system vibration on driver comfort.

The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is described further:
As shown in the figure, the utility model provides a kind of pair of cushion shock attenuation unit, comprise the first support 1 and the second support 2, be provided with the first cushion 3 between described the first support 1 and the second support 2, be provided with the second cushion 4 on described the second support 2, be provided with pad 5 on described the second cushion 4, 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 the 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 the pad 5.
In the 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.
When muffler assembly 9 was in static state, 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 had certain compressive deformation.Pad 5 makes the second cushion 4 upper surfaces stressed evenly.
When muffler assembly 9 upwards vibrates, the vibration that the first cushion 3 is made progress by the first support 1, pressure increases, and compressive deformation increases, 3 main damping of vibrationss of the first cushion; During muffler assembly 9 vibration downwards, the second cushion 4 is subjected to the downward vibration of pad 5, and pressure increases, and compressive deformation increases, 4 main damping of vibrationss of the second cushion.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and scope of the present invention.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
The content that is not described in detail in this specification sheets belongs to the known prior art of this area professional and technical personnel.
