Patent number: 11885402Abstract: A gearcase seal assembly includes an inboard seal body and an outboard seal body both extending about and along a center axis between respective interior and exterior portions. The inboard and outboard seal bodies include respective inboard and outboard pockets configured to receive first and second surfaces of a gearcase of an axle assembly, respectively. The interior portions of the inboard and outboard seal bodies include respective gutters configured to direct fluid away from the first and second surfaces of the gearcase, respectively. The exterior portion of the inboard seal body includes plural fingers disposed outside of the inboard pocket and extending in one or more directions away from the inboard pocket. The exterior portion of the outboard seal body includes plural other fingers disposed outside of the outboard pocket and extending in one or more directions away from the outboard pocket.Type: GrantFiled: June 30, 2021Date of Patent: January 30, 2024Assignee: Transportation IP Holdings, LLCInventors: Andrew Lee Payne, Scott Patrick Leute, Santosh Reddy Sama, Uday Prakash Karmarkar, Jaime de Jesus Garcia, Dennis Richter, Elizabeth Wooden

Patent number: 11231107Abstract: A seal structure can include a protruding portion of an outer surface of a body. An inner surface of the protruding portion may define at least a portion of a channel. The protruding portion may be configured to engage and at least partially deform into the channel in response to a load generated by pressing an outer surface of the protruding portion against a contact surface of a contact member to provide a seal between the body and the contact member. The seal structure may be integrally formed within the body as a monolithic object. The body may face towards the contact surface of the contact member during operation of the seal structure. A method may include forming a monolithic body with an integral seal structure by additively fusing material so that the body has an outer surface facing towards a contact surface of a contact member.Type: GrantFiled: November 22, 2019Date of Patent: January 25, 2022Assignee: Transportation IP Holdings, LLCInventors: Uday Prakash Karmarkar, Dennis Richter, Krishna Kumar Gupta, Jaime Jesus Garcia, Erik W. Miller
