Embodiment Construction

[0030] Exemplary embodiments of the present disclosure include a transmission housing enclosing a power transfer component having a sound dampening coating applied directly on a surface of the housing. In contrast to conventional sound deadening systems and methods, the present invention completely avoids the cost and complexity of providing a completely separate transmission housing sound deadening cover.

[0031] figure 1 is a flowchart illustrating a method 100 according to an exemplary embodiment of the present disclosure. The method starts at step 102 and continues to step 104 . In step 104 , the method provides a transmission housing and continues to step 106 . In step 106 , the method cleans the surface of the transmission housing and continues to step 108 . In step 108 , the method applies sound deadening material to the surface of the transmission housing and continues to step 110 . In step 110 , the method cures the applied sound deadening material by, for exampl...

Abstract

A method for applying a sound dampening coating on a surface of a vehicle transmission housing includes providing the transmission housing, and applying a sound dampening material directly on a surface of the transmission housing.

Description

technical field [0001] The present disclosure relates to a sound deadening coating for a vehicle transmission housing and a method for applying a sound deadening coating on a transmission housing. Background technique [0002] This Introduction generally gives the context of the disclosure. Work of the presently mentioned inventors within the scope described in this Introduction and aspects of the description that may not be prior art at the time of filing are neither expressly nor impliedly admitted to be prior art to the present disclosure. [0003] A vehicle transmission may include a housing surrounding components that transmit power from a prime mover to a drive member. The power transfer components can generate vibrations and / or noise that can be transferred to the housing and from the housing to the surrounding environment. Those surroundings may include the body of the vehicle housing the passenger compartment. Noise generated by the transmission may be transmitte...
