Problems solved by technology

[0003] In more and more practices, we find that only the traditional suspension structure is selected, see figure 1 , the traditional similar structure is mainly based on the active side cushion 1 vibration isolation, without the passive side rubber cushion, in some specific cases (such as the situation with higher requirements for comfort performance), it can no longer fully meet the ever-changing High-tech engine vibration characteristics require that the suspension structure must be optimized according to different engine dynamic characteristics, thereby improving the NVH characteristics of the car

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0021] see figure 2 , image 3 with Figure 4 , the active side cushion 1 of the automobile engine mount cushion assembly is a conventional bushing structure cushion, which is composed of a rubber main spring, an inner sleeve 2 and an outer sleeve. The passive side cushion 3 is a bushing structure cushion with small volume and high rigidity, which is composed of the passive side rubber main spring 6 and the inner and outer sleeves 5 and 7 . The active and passive side cushions are interference fit with the metal frame. The active side cushion 1 is installed in the middle of the metal frame 4, and the two ends of the metal frame have connecting holes for connecting the side beams of the vehicle body or the chassis, and the two passive side cushions 3 are assembled at the connecting holes, which interfere Cooperate, the inner casing 5 of the passive s...

Abstract

The invention provides an automobile engine suspension cushion assembly which comprises a driving side cushion, driven side cushions and a metal supporting frame. The driving side cushion is arranged on the metal frame and is in interference fit with the metal frame, automobile body longitudinal beams or connecting holes of a chassis are connected with the two ends of the metal frame, the driven side cushions are assembled on the connecting holes and are in interference fit with the connecting holes, and driven side cushion inner sleeve tubes of the driven side cushions and the connecting holes are concentric. The mode that the driving side rubber cushion and the driven side rubber cushions are integrated through the metal support is adopted, the driving side cushion is mainly stressed, the driven side cushions achieve the functions of auxiliary adjusting and vibration isolation and system decoupling, and the ideal vibration isolation effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile powertrain suspension systems, and in particular relates to an automobile powertrain suspension cushion assembly structure. Background technique [0002] The development trend of automobiles is rapidly developing towards lightweight, miniaturization, low cost, low noise, and comfort. The engine, which is the heart of the automobile, is the main source of vibration. Passed to the body, and then passed to the cockpit. The powertrain suspension system is the elastic connection system between the powertrain and the body, which mainly plays the role of support, limit and vibration isolation. Therefore, the quality of the suspension system design directly affects the ride comfort of the car. The NVH characteristics of the car can be improved to a great extent by optimizing the design of the suspension system. [0003] In more and more practices, we find that only the traditional suspension structu...
