Abstract
The invention discloses a kind of car exhaust pipe fixed equipment, including elastic fixing device and damping unit, elastic fixing device and damping unit is interlaced arranges along exhaust pipe；The elastic fixing device includes the fixing seat of the first clip of lower part, top, and the first clip fixes exhaust pipe, and fixing seat two-side elastic is fixed on vehicle chassis；The damping unit includes the damper of the second clip of lower part, top, and the second clip fixes exhaust pipe, and damper is fixed on vehicle chassis.The present invention can prevent frictional impact between exhaust pipe and chassis, extend the service life of exhaust pipe.
Description
Technical field
The present invention relates to a kind of car exhaust pipe fixed equipments.
Background technique
Automobile exhaust pipe is fixed below chassis of vehicle body, and is connect with engine.In the process of moving due to automobile, start
Chance generates certain vibration, thus will drive exhaust pipe and generates certain vibration, and during high vehicle speeds, exhaust
It fixes bad between pipe and chassis, will interact, collide with mutually, influence the service life of exhaust pipe.
Summary of the invention
The object of the present invention is to provide a kind of car exhaust pipe fixed equipment, can prevent from rubbing between exhaust pipe and chassis
Collision, extends the service life of exhaust pipe.
To achieve the above object, a kind of car exhaust pipe fixed equipment that the present invention uses, including elastic fixing device and
Damping unit, elastic fixing device and damping unit is interlaced arranges along exhaust pipe；The elastic fixing device includes
First clip of lower part, top fixing seat, the fixed exhaust pipe of the first clip, fixing seat two-side elastic is fixed on vehicle chassis
On；The damping unit includes the damper of the second clip of lower part, top, and the second clip fixes exhaust pipe, and damper is fixed
On vehicle chassis.
Further, the fixing seat is bolted on vehicle chassis, and coaxial spring, bullet are equipped in the middle part of bolt
Spring is between vehicle chassis and fixing seat.
Further, the bolts and nuts cooperation, is equipped with elastomeric pad between nut and vehicle chassis.
Preferably, the elastic fixing device and damping unit are all made of stainless steel material.
Preferably, the side that first clip and the second clip are contacted with exhaust pipe is equipped with flexible pad.
Elastic fixing device and damper cooperate, can while fixed exhaust pipe, by the vibration of exhaust pipe with
The vibration isolation on chassis comes, and prevents to resonate, or generates subtle collision, increases the service life of exhaust pipe.Meanwhile this
The structure of invention is simple, easy for installation, has biggish practicability and economic value.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
In figure: 1. exhaust pipes, 2. elastic fixing devices, 21. first clips, 22. fixing seats, 23. springs, 24. elastic cushions
Piece, 25. nuts, 26. bolts, 3. vehicle chassis, 4. damping units, 41. second clips, 42. dampers.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of fixed device of automobile exhaust pipe 1, including elastic fixing device 2 and damping unit 4, elasticity are solid
Determine device 2 and damping unit 4 is interlaced along the arrangement of exhaust pipe 1；Elastic fixing device 2 includes the first clip of lower part
21, the fixing seat 22 on top, the fixed exhaust pipe 1 of the first clip 21,22 two-side elastic of fixing seat are fixed on vehicle chassis 3；Resistance
Buddhist nun's device 4 includes the damper 42 of the second clip 41 of lower part, top, and the second clip 41 fixes exhaust pipe 1, and damper 42 is fixed
On vehicle chassis 3.
As further embodiment, as shown in Figure 1, fixing seat 22 is fixed on vehicle chassis 3 by bolt 26, bolt 26
Middle part is equipped with coaxial spring 23, and spring 23 is between vehicle chassis 3 and fixing seat 22.
Further, as shown in Figure 1, bolt 26 and nut 25 cooperate, elastic cushion is equipped between nut 25 and vehicle chassis 3
Piece 24.
In order to increase service life, it is preferred that elastic fixing device 2 and damping unit 4 are all made of stainless steel material.
When the first clip 21 and the second clip 41 hold exhaust pipe 1 tightly in order to prevent, exhaust pipe 1 is damaged, it is preferred that the first card
The side that hoop 21 and the second clip 41 are contacted with exhaust pipe 1 is equipped with flexible pad.
Elastic fixing device 2 and damper 42 cooperate, can be while fixed exhaust pipe 1, by the shake of exhaust pipe 1
The dynamic vibration isolation with chassis comes, and prevents to resonate, or generates subtle collision, increases the service life of exhaust pipe 1.Together
When, structure of the invention is simple, and it is easy for installation, there is biggish practicability and economic value.
