Problems solved by technology

However, passive noise reduction measures such as sticking damping and acoustic wrapping adopted by a small number of transmission manufacturers currently only control the structural vibration or the transmission of airborne sound energy, and do not consider them at the same time. Rubber softening and poor durability, so it has not been widely promoted

Embodiment Construction

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further elucidated by taking the case of a self-cooling, vibration-suppressing and noise-reducing transmission housing partly laid with a vibration-suppressing and sound-insulating structure in conjunction with the accompanying drawings. It should be understood that the following specific embodiments are only used to illustrate the present invention but not to limit the scope of the present invention.

[0029] refer to figure 1 , 2 , 3. The self-cooling, vibration-suppressing and noise-reducing transmission housing of the present invention includes a main housing 1 and a vibration-suppressing and sound-insulating structure 4 . The surface of the main shell 1 is provided with a number of axial reinforcement ribs 2 and a number of circumferential reinforcement ribs 3 to enhance the structural strength, optimize the str...

Abstract

The invention provides a self-cooling vibration suppression and noise reduction transmission shell. The self-cooling vibration suppression and noise reduction transmission shell comprises a main shelland a vibration suppression and sound insulation structure; the vibration suppression and sound insulation structure is installed on the outer surface of the main shell, and a cooling liquid flowingcavity is formed between the inner surface of the vibration suppression and sound insulation structure and the outer surface of the main shell; and a damping layer is arranged in the vibration suppression and sound insulation structure. Transmission of shell vibration and radiated sound energy can be reduced at the same time, the NVH performance of a transmission is greatly improved, the surface temperature of the shell is decreased through a circulating cooling system, and the good working performance of the vibration suppression and sound insulation material is guaranteed.

Description

technical field [0001] The invention relates to a transmission, in particular to a self-cooling vibration suppression and noise reduction transmission casing. Background technique [0002] In order to meet the requirements of drivers and passengers for the comfort of modern vehicles, the transmission is one of the key components of the transmission system, and it is urgent to further reduce its structural vibration and radiation noise, especially for the field of new energy vehicles. [0003] Due to the working performance requirements such as bearing capacity and durability, the noise reduction space of active noise reduction schemes such as gear structure optimization and shape modification is becoming more and more limited; passive noise reduction measures to control noise from the transmission path do not affect the structure layout and structure of the transmission. work performance. However, passive noise reduction measures such as sticking damping and acoustic wrappi...
