Patent number: 11529688Abstract: A hydraulic-expansion chuck for clamping a workpiece includes an annular body, an inner circumferential surface, an outer circumferential surface, and an axis of rotation. The chuck also includes a channel integrated into the annular body for receiving a pressurized hydraulic fluid to clamp the workpiece. The channel has an annular peripheral channel section formed radially between the inner circumferential surface and the outer circumferential surface. The chuck also includes a holding contour with a plurality of expansion lugs disposed on the inner circumferential surface and a plurality of further channel sections branching off from the channel. At least one of the plurality of further channel sections extends into a respective lug of the plurality of expansion lugs, and the hydraulic-expansion chuck is manufactured by an additive manufacturing process.Type: GrantFiled: February 28, 2019Date of Patent: December 20, 2022Assignee: Shaeffler Technologies AG & Co. KGInventors: Claus Schaeperkoetter, Stefan Becke, Michael Mayer

Patent number: 11207935Abstract: An air suspension system of a commercial vehicle comprises an electronic control device with a level control valve device. A valve element is coupled to a drive element mechanically coupled to a vehicle wheel or axle. In a first relative position of the valve element and a counter valve element, a port for an air suspension bellow is blocked. In a second relative position, the port for the air suspension bellow is connected to a port for an aeration device. In a third relative position, the port for the air suspension bellow is connected to a port for a deaeration device. Control logic generates a control signal for an actuator which, when a level change is set by an operator, correspondingly changes the relative position of the valve element and the counter valve element or the relative position of the counter valve element and a valve housing.Type: GrantFiled: August 20, 2018Date of Patent: December 28, 2021Assignee: HALDEX BRAKE PRODUCTS AKTIEBOLAGInventors: Dudley Harrison, Carl Mellings, Georg Sulzyc, Christian Schering, Siegfried Heer, Stefan Becke, Joachim Noecker, Tobias Tschoeke, Arne Busch

Patent number: 10814691Abstract: A mechanically actuated level control valve device for a commercial vehicle with an air suspension system is a level control valve and comprises a drive element that can be mechanically coupled to a vehicle wheel or axle. A valve element and a counter valve element have a first relative position, wherein the port for the air suspension bellow is closed, a second relative position, wherein the port for the air suspension bellow is connected to the port for the aeration device, and a third relative position, wherein the port for the air suspension bellow is connected to the port for the deaeration device. The valve element is coupled to a rotatable driveshaft of the level control valve by a drive mechanism. An integrated actuator changes the relative position of the valve element and the drive element or the relative position of the counter valve element and a valve housing.Type: GrantFiled: August 20, 2018Date of Patent: October 27, 2020Assignee: HALDEX BRAKE PRODUCTS AKTIEBOLAGInventors: Dudley Harrison, Carl Mellings, Georg Sulzyc, Christian Schering, Siegfried Heer, Stefan Becke, Joachim Noecker, Tobias Tschoeke, Arne Busch
