Patent number: 11600890Abstract: A battery pack assembly includes at least one battery cell and a terminal connector mechanism. The at least one battery cell has at least one terminal which includes a terminal engagement portion. The terminal connector mechanism has a retention member and a biasing member. The retention member has retention portion and is configured to move between an engaged position and a disengaged position. The biasing member is positioned between the housing and the retention member to bias the retention member towards the engaged position. In the engaged position, the retention portion of the retention member engages with the terminal engagement portion to inhibit movement of the terminal connector mechanism. In the disengaged position, the retention portion of the retention member is disengaged from the terminal engagement portion to permit movement of the terminal connector mechanism.Type: GrantFiled: May 11, 2020Date of Patent: March 7, 2023Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Nicholas S. Vernon, Joshua D. Yaksich

Patent number: 10948081Abstract: A continuously variable transmission, a vehicular powertrain that includes a continuously variable transmission and a method of limiting belt slippage in a continuously variable transmission in a vehicle. The continuously variable transmission includes a pulley assembly, shafts, a clutch and hydraulic system. The hydraulic system is cooperative with both the clutch and the pulley assembly so that hydraulic pressures and associated clamping forces sent to both allow the clutch to preferentially absorb any driving load coming from the axle and wheels that is in excess of the normal load experienced at the continuously variable transmission. This in turn means that any additional load that would ordinarily cause slippage in the belt is instead experienced by the clutch.Type: GrantFiled: March 2, 2017Date of Patent: March 16, 2021Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Luke A. Rippelmeyer, Nicholas S. Vernon

Patent number: 10428931Abstract: A planetary carrier subassembly for a transmission is provided that is sintered using braze preforms. The carrier subassembly may include a powder metal carrier member having a plurality of carrier legs extending a distance therefrom, and a powder metal cover member having a plurality of cover legs extending a distance therefrom. The carrier member and cover member are positioned such that respective ends of the carrier legs and ends of the cover legs are aligned with one another. The subassembly is provided with at least one braze preform including a braze material and a sacrificial binder, such as a wax. The braze preform is placed between a respective pair of the aligned carrier legs and the cover legs. The braze preform is provided with a geometry configured to direct a flow of braze material during a subsequent sintering process.Type: GrantFiled: February 27, 2017Date of Patent: October 1, 2019Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Shail N. Shah, Brady Gambatese, Nicholas S. Vernon

Publication number: 20180031115Abstract: A powder metal component for a transmission includes a body portion defining a substantially planar major surface, and at least three radially spaced-apart retention features formed in the body portion in a green state, prior to sintering. Each retention feature may include a bore having a shaped geometry extending between an upper region adjacent the major surface of the body portion, and a lower region defining a radius of curvature. Each bore may be defined by two opposing, substantially parallel sidewalls and a substantially U-shaped bottom portion. The U-shaped bottom portion may include a center region defining the radius of curvature connecting two angled bottom walls.Type: ApplicationFiled: July 26, 2016Publication date: February 1, 2018Inventors: Shail N. Shah, Nicholas S. Vernon, Sean I. Hayes
