Patent number: 10160060Abstract: A weld joint includes a first component of a first material and a second component of a ductile second material dissimilar from the first material. A planar face of the first component abuts a planar face of the second component. A āVā shaped weld groove is created in the first component defining a first groove end where a substantially planar groove face of the first component intersects a plane defined by the planar face of the second component below an end face of the second component. A slot is created below the groove end in the planar face of the second component having a closed end facing toward the end face of the second component and extending away from the planar face of the second component at an angle measured with respect to a central longitudinal axis of the slot.Type: GrantFiled: November 10, 2015Date of Patent: December 25, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Huaxin Li, Yujiro Suwa, Nieyuan Hai

Patent number: 9356493Abstract: A motor housing assembly is formed by positioning a stator relative to a motor housing to configure a fillable gap between the stator and the motor housing, and filling the fillable gap is at least partially with a polymeric material to form a thermally conductive layer. The polymeric material may include a metallic filler material. The thermally conductive layer is in contact with an exterior surface of the stator and an interior surface of the motor housing adjacent the exterior surface of the stator, and is configured to cover at least half of the exterior surface. A method to form the thermally conductive layer includes injecting a high flow polymeric material through a port defined by the housing and in fluid communication with the fillable gap.Type: GrantFiled: February 26, 2013Date of Patent: May 31, 2016Assignee: GM Global Technology Operations LLCInventors: Charles K. Buehler, Nieyuan Hai

Patent number: 8959911Abstract: A powertrain assembly includes an internal combustion engine, a boost mechanism and a fluid supply mechanism. The boost mechanism is in communication with an air source and the internal combustion engine. The fluid supply mechanism includes a first accumulator in communication with a pressurized fluid supply from the internal combustion engine and the boost mechanism. The accumulator receives pressurized fluid from the internal combustion engine during engine operation and provides the pressurized fluid to the boost mechanism during an engine off condition.Type: GrantFiled: October 6, 2011Date of Patent: February 24, 2015Assignee: GM Global Technology Operations LLCInventors: William C. Deneszczuk, Mary T. Lapres-Bilbrey, Michael Simon, Nieyuan Hai

Patent number: 8677742Abstract: An accumulator includes a canister, a piston, a sleeve, and a solenoid control valve assembly. The canister has an inner surface that defines an interior volume. The piston is slidably disposed within the interior volume of the canister. The piston is located between the inner surface of the canister and an outer surface of the sleeve. The piston divides the interior space into a fluid filled chamber and an air filled chamber. A fluid pathway is created by an outer surface of the sleeve and the inner surface of the canister. The fluid pathway allows fluid from an exterior source to either enter or exit the fluid chamber. The solenoid control valve assembly includes a valve body, a valve biasing member, and a plunger that is slidable within a recess of the valve body.Type: GrantFiled: February 1, 2011Date of Patent: March 25, 2014Assignee: GM Global Technology Operations LLCInventors: Leonid Basin, Fredrick R. Poskie, Nieyuan Hai, Carlos E. Marin
