Abstract
The utility model discloses a hanging structure for an automobile exhaust system, comprising an underframe, a first hanging hook arranged on the underframe through a hanging hook connecting plate and a third hanging hook arranged on the exhaust system, wherein the first hanging hook and the third hanging hook are connected with each other through a rubber hanging block. The hanging structure for the automobile exhaust system is characterized in that the underframe is provided with a second hanging hook connected with the rubber hanging block; and mounting holes used for connecting the first hanging hook, the second hanging hook and the third hanging hook with the rubber hanging block are triangularly distributed, thereby achieving the purpose of hanging the exhaust system by the underframe; the modal stiffness of hanging points on the underframe can be improved through the first hanging hook and the second hanging hook which are connected together side by side; and by hanging the exhaust system through the rubber hanging block provided with the three mounting holes, the exhaust system can be controlled to rotate around the hanging points on the underframe in the case of the ineffectiveness of the rubber hanging block, therefore, noise generated due to the impact between the exhaust system and the underframe can be eliminated.
Description
Technical field
The utility model relates to a kind of automobile exhaust system hanging structure, can improve the NVH performance of vehicle, at the durability of vehicle use.
Background technology
Development along with automotive technology, the customer is not only to the higher requirement of proposition of the safety of vehicle, to the requirement of traveling comfort also in progressively raising, vehicle under steam, vibration and influence of noise occupant's traveling comfort, first vibration of vehicle is exactly the vibration of exhaust system, after the hanging structure of exhaust system surpasses the life cycle inefficacy, the vibration of exhaust system and rocking of self may produce noise with the body bottom panel wipe contact, be delivered in the crew module by the vehicle body media, reduced occupant's traveling comfort.
At present, the exhaust system hanging structure of common vehicle is: body bottom panel is provided with the suspension hook of hanging exhaust system, exhaust system is provided with the suspension hook of hanging, each sling point position body bottom panel and exhaust system respectively have a suspension hook, connect together by an elastic block rubber in the middle of suspension hook on the exhaust system and the suspension hook on the body bottom panel, constitute the erecting by overhang of exhaust system.Elastic block rubber plays the effect that vibration isolation, sound insulation are propagated, and the transfer of vibration in the time of in theory can the separated exhaust system works is in the crew module.But there is technical defective in this structure, because any material all has service life, exhaust system is under the condition of high temperature all the time in the vehicle ', and rubber hangs the block length time and works under high temperature and various complex working condition, and very fast inefficacy does not play vibration isolation.In addition, rubber hangs piece inefficacy back and produces the gap with the suspension hook of body bottom panel and the suspension hook cooperation place of exhaust system, the suspension hook of exhaust system will be that pivot point rotates with the suspension hook of body bottom panel, along with travelling of vehicle, exhaust system is around the suspension hook swing of body bottom panel, and the degree of depth of hanging piece along with rubber lost efficacy, and the exhaust system oscillating quantity increases, the risk that strikes body bottom panel is arranged, produce the traveling comfort of influence of noise to the occupant.
Disclosed cargo hook gear of motor vehicle exhaustion system of Chinese patent CN200710114995.4 and the hollow suspension hook of the disclosed automobile exhaust system of Chinese patent CN200920172415.1 all do not solve rubber and hang the vibration of piece inefficacy final vacuum system and the bump generation vibration and the noise problem of increase of rolling momentum and body bottom panel.
The utility model content
Technical problem to be solved in the utility model is, a kind of automobile exhaust system hanging structure is provided, hang the noise that produced after piece lost efficacy to reach the vibration and the rubber that reduce exhaust system, improve the hanging structure of existing exhaust system, improve the NVH of vehicle and the purpose of durability.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of automobile exhaust system hanging structure comprises body bottom panel and goes up first suspension hook that is provided with by the suspension hook connecting panel, the 3rd suspension hook that is provided with on the exhaust system, and described first suspension hook hangs piece with the 3rd suspension hook by rubber and connects; It is characterized in that: second suspension hook is set on body bottom panel, and described second suspension hook hangs piece with rubber and connects; What described first suspension hook, second suspension hook, the 3rd suspension hook and rubber hung piece connects mounting hole distribution triangular in shape.
Further, described first suspension hook is that an end has hemispherical round steel bending shape, and described second suspension hook is the round steel bending shape, and described suspension hook connecting panel has groove structure; Described first suspension hook and two on second suspension hook connect side by side with suspension hook connecting panel groove and weld.
The beneficial effects of the utility model are, owing to adopt two suspension hooks that connect side by side can improve the modal stiffness of body bottom panel sling point, no matter vehicle travels under which kind of operating mode, the body bottom panel sling point does not deform, and strengthens the local strength and the rigidity of body bottom panel sling point again.Hang exhaust system rubber hang piece adopt 3 fixing, 2 points on the body bottom panel, a bit, 3 fixing just can control rubber and hang the rotation of piece inefficacy final vacuum system around the vehicle body suspension centre on the exhaust system, the bump of elimination exhaust system and body bottom panel and produce noise.This structure has the following advantages: 1, the sling point of exhaust system increases by an attachment point, alleviates the rolling momentum of exhaust system, the vibration that alleviates exhaust system; 2, increase the modal stiffness of the sling point of exhaust system; , 3, simple in structure, low cost of manufacture is convenient to large batch of production and repacking; 4, improve the durability that the automobile exhaust system hanging structure uses.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
