Patent number: 11320047Abstract: A transmission assembly for an electric drive comprises a drive shaft, a reduction gearing rotatably drivable by the drive shaft, a power distribution unit drivingly connected to the reduction gearing and configured to transmit a rotational motion to two output parts, a parking lock unit having a parking ratchet wheel which is connected in a rotationally fixed manner to a torque-transmitting member in the power path between the drive shaft and the output parts, and having a controllable locking element which can be selectively engaged with the parking ratchet wheel; wherein the parking lock unit is arranged in a parking lock housing which is liquid-tightly sealed with respect to a transmission housing so that a first oil bath in the transmission housing is separated from a second oil bath in the parking lock housing.Type: GrantFiled: June 29, 2018Date of Patent: May 3, 2022Assignee: GKN Automotive LimitedInventors: Sascha Miebach, Mark Schmidt, Ervin Szilagyi

Patent number: 11313464Abstract: A parking lock unit for a drive assembly, in particular with an electric motor, comprises a parking lock housing, a ratchet wheel rotationally fixedly connected to a part of the drive assembly, which is rotatably supported about a rotational axis by at least one bearing, and comprising a connecting portion and an engagement portion which are connected to one another via a web portion; a locking element which is supported in the parking lock housing and can lock and release a rotational movement of the parking ratchet wheel about a longitudinal axis of the parking ratchet wheel, and a controllable locking actuator which can reversibly transfer the locking element into a position locking the parking ratchet wheel and a position releasing the parking ratchet wheel, wherein the parking ratchet wheel is formed such that the engagement portion is axially offset with respect to the connecting portion.Type: GrantFiled: April 26, 2018Date of Patent: April 26, 2022Assignee: GKN Automotive LimitedInventors: Sascha Miebach, Mark Schmidt, Simon Broicher, Ervin Szilagyi

Patent number: 11248702Abstract: A parking lock unit for a transmission assembly of a motor vehicle includes a parking ratchet wheel defining a longitudinal axis and a first spring arrangement. A second spring arrangement is arranged radially outwards of the first spring arrangement with respect to a longitudinal axis. A supporting sleeve is arranged coaxially to the parking ratchet wheel and is supported in a circumferential direction by the transmission assembly. The supporting sleeve has at least one opening. At least one locking element is arranged between the first and second spring arrangements and is radially movable in the at least one opening with respect to the longitudinal axis. The locking element is spring loaded by at least one of the first and second spring arrangements. The at least one locking element is movable radially inwards into a locked position and radially outwards into a release position by rotation of an actuating ring about the longitudinal axis.Type: GrantFiled: April 5, 2019Date of Patent: February 15, 2022Assignee: GKN Automotive Ltd.Inventors: Artur Grunwald, Sascha Miebach

Patent number: 10435001Abstract: In order to provide a hydraulic actuating system for actuating a parking lock of a motor vehicle, which hydraulic actuating system manages with as few components as possible which are simple, robust, relatively insusceptible to faults and inexpensive, with a simultaneously low installation space requirement, and the hydraulic layout of which hydraulic actuating system makes a simple actuation and a simple movement possible for locking and unlocking the parking lock, it is provided that a pumping device which can operate bidirectionally with a locking delivery direction and with a releasing delivery direction is used as pumping device, and check valves are arranged in the hydraulic circuit in such a way that, by way of actuation of the pumping device in the locking delivery direction, the parking lock moves into the locked position and, upon actuation of the pumping device in the releasing delivery direction, the parking lock moves into the released position.Type: GrantFiled: August 24, 2017Date of Patent: October 8, 2019Assignee: GKN Automotive Ltd.Inventors: Reinhard Möhlmann, Sascha Miebach
