Patent number: 12000432Abstract: A radial air bearing device includes a bearing plate, a spring steel sheet, and a bearing receptacle. The bearing plate includes one or more bearing plate parts with an inner main side and two wide sides. First and second retaining lugs are provided on each wide side and are bent to the outside. The spring steel sheet includes one or more spring steel sheet parts. The bearing receptacle includes a recess with an inner wall and a first groove and a second groove which extend outwards from the recess. The first groove is arranged axially offset with respect to the second groove. The bearing plate parts and the spring steel sheet parts are arranged along the inner wall so that the spring steel sheet runs between the bearing plate and the inner wall and so that the first and second retaining lugs engage in the first or second groove.Type: GrantFiled: May 13, 2022Date of Patent: June 4, 2024Assignee: BorgWarner Inc.Inventor: Sebastian Dauscher

Patent number: 11920490Abstract: A charging device (10) for an internal combustion engine or a fuel cell, including a compressor (100) with a compressor housing (110) and a compressor wheel (120) arranged therein. The charging device (10) also includes a shaft (200) which is coupled to the compressor wheel (120), and a bearing housing (300) which is connected to the compressor housing and in which the shaft (200) is rotatably mounted. The bearing housing (300) includes a thrust bearing (400) for axial mounting of the shaft (200). The thrust bearing (400) has a bearing gap (410) which extends at least partially in a radial direction (24) relative to the shaft (200). The thrust bearing (400) is fluidically connected to the compressor (100) and arranged such that when the compressor (100) is in operation, a fluid stream from the compressor (100) flows at least partially in the radial direction (24) through the bearing gap (410). The thrust bearing (400) is fluidically connected to a pressure side (130) of the compressor (100).Type: GrantFiled: September 19, 2022Date of Patent: March 5, 2024Assignee: BorgWarner Inc.Inventor: Sebastian Dauscher
