Problems solved by technology

[0004] The commonly used rubber suspension blocks are prone to fatigue damage under high temperature, repeated vibration and pulling, especially when the car is driving on uneven roads, the weight of the exhaust system is large and the vibration of the vehicle is increased. The block will be stretched seriously, seriously affecting the life of the hanging block, breaking in a short time, affecting the performance and safety of the whole vehicle; if in order to ensure the reliability of the hanging block, make the hanging block larger or harder, It will affect the shock absorption performance of the hanging block, cause noise in the car, and affect the ride comfort.

Embodiment 1

[0026] The installation scheme of the vehicle body and the exhaust pipe on the suspension block 8 proposed by the present invention is: because the exhaust pipe hook and the vehicle body hook part for fixing the exhaust pipe are cylindrical, the described vehicle body The installation part 10 is provided with a car body joint hole 4, and the hook on the automobile body is packed into the car body joint hole 4; the exhaust pipe installation part 9 is provided with an exhaust pipe joint hole 2, and the exhaust pipe of the automobile exhaust system Install the pipe hook into the exhaust pipe joint hole 2. In this way, the relative position of the bodywork and the exhaust pipe will not change due to vibrations.

Embodiment 2

[0028] Example for limiting excessive vibration amplitude: on the surface of the metal frame 3, there are shock-absorbing rubber pads 1, 5 made of rubber materials, and the shock-absorbing rubber pads 1, 5 are wrapped around the metal frame 3. On the surface, it is integrated with the metal frame 3. This connection generally adopts integral molding or bonding.

[0029] The hanging block 8 of the rubber material provided by the present invention allows the elastic coefficient of the rubber material to be small, but under flat road conditions, the vehicle body mounting part 10 connected to the vehicle body and the shock-absorbing rubber pad 5 and the exhaust gas connected to the exhaust system The pipe installation part 9 does not contact the shock-absorbing rubber pad 1, which can fully absorb the vibration of the exhaust system and meet the NVH performance and comfort requirements. When running into poor road conditions, the vehicle body installation part 10 connected with th...

Embodiment 3

[0031] Embodiment of the shape of the vehicle body mounting part 10 and the exhaust pipe mounting part 9: the vehicle body mounting part 10 and the exhaust pipe mounting part 9 are cylindrical, and the axes of the two cylinders are parallel; The axis of the hole 4 coincides with the axis of the vehicle body mounting portion 10 ; the axis of the exhaust pipe coupling hole 2 coincides with the axis of the exhaust pipe mounting portion 9 . The car body mounting part 10 and the exhaust pipe mounting part 9 adopt a cylindrical shape, and the holes are located at the axial position, which is convenient for processing and difficult to damage.

Abstract

The present invention discloses one kind of automobile exhaust system mounting hanger. One metal frame is set around the hanger, the automobile body installation unit and the exhaust pipe installation unit; and the automobile body installation unit and the exhaust pipe installation unit are fixed through supporting and connecting parts of rubber onto the metal frame. Compared with available technology, the present invention has the advantages of long service life, good vibration reducing performance, high fatigue resistance, etc.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to an exhaust system in an automobile power assembly, more specifically, the invention relates to a suspension block for installing an automobile exhaust system. Background technique [0002] At present, the exhaust system of a car is installed on the car body using a suspension block made of pure rubber material. [0003] Due to the improvement of consumers' requirements for automobile NVH (noise, vibration and harshness) and the improvement of environmental protection requirements, the quality of automobile mufflers and three-way catalytic converters has become larger, the exhaust temperature is high, the working environment of hanging blocks is harsh, and the automobile exhaust Due to its own structural limitations, the system installation hanging block is increasingly unable to meet the requirements of use. It is difficult for rubber materials to meet the requirement...
