Patent number: 10451073Abstract: An electric motor driven fluid pump for forced lubrication of a manual transmission of a motor vehicle, includes a housing having a fluid inlet and a fluid outlet, and an electronically commutated electric motor incorporated therein. The electric motor has a substantially cup-shaped magnetic rotor rotatable around a rotational axis, shaped for conveying fluid, an annular stator having a motor winding which at least partially encloses the rotor in a coaxial arrangement with respect to the rotational axis when viewed along the rotational axis, and a magnetic field sensor for detecting the position of the rotor. The housing includes a stator housing section which holds the stator, separates same from a liquid chamber in which the rotor is arranged, and extends into the rotor by a housing offset formed for receiving the magnetic field sensor.Type: GrantFiled: September 22, 2014Date of Patent: October 22, 2019Assignee: FTE automotive GmbHInventors: Karin Fecke, Markus Dirauf, Alexander Reul, Wilhelm Will, Jürgen Otto, Roland Stössel

Patent number: 10393120Abstract: An electric motor driven liquid pump, which can be used for forced lubrication of a motor vehicle manual transmission, has a housing flange-mountable on a fluid container via a flange surface. A stator including a motor winding and a magnetic rotor are incorporated in the housing for conveying liquid. The housing is formed of multiple parts including a pump housing section which has fluid inlets and outlets, a stator housing section which holds the stator and together with the pump housing section, delimits an electronics chamber in which the rotor is arranged, and a motor housing section which together with the stator housing section delimits an electronic chamber in which at least the stator is located. A sealing element seals the flange surface to the fluid container, separates the fluid chamber and the electronic chamber, and seals the latter from the environment.Type: GrantFiled: September 23, 2014Date of Patent: August 27, 2019Assignee: FTE automotive GmbHInventors: Alexander Reul, Roland Stössel

Patent number: 10385966Abstract: A hydraulic operating device for operating actuators in a motor vehicle transmission has at least two actuation cylinders each containing a cylinder housing. An actuation piston is guided therein along a cylinder axis in a longitudinally displaceable manner. Each actuation piston can be hydraulically loaded and is operatively connected to one of the actuators. The actuation cylinders are combined into a unit that can be flange-mounted on one side, via a flange face, to a dividing wall of a transmission housing of the motor vehicle transmission. The cylinder housings are injection molded from plastic integrally with a flange plate that runs transversely to the cylinder axes, the flange face being formed on the flange plate. The cylinder housings protrude beyond the flange plate, at least on the side of the flange face, in the direction of the cylinder axes.Type: GrantFiled: July 23, 2015Date of Patent: August 20, 2019Assignee: FTE automotive GmbHInventors: Egid Macht, Roland Stössel, Reinhold Stöhr, Karin Fecke, Dietmar Fuchs, Alexander Reul, Wilhelm Will, Christian Voigt, Wilhelm Heubner

Patent number: 10337513Abstract: A liquid pump has a housing with a suction connection, a pressure connection and a electric motor for rotationally driving a conveying device that has a suction inlet and pressure outlet which communicate with the suction connection and the pressure connection respectively. An electronic power unit for the electric motor is adjacent to the motor and extends transversely to the axis of rotation and is on the rear side of the partition wall of the housing. The suction inlet is arranged at a height smaller than an inner radius of an annular gap between the stator and rotor, whereas a rotor passage extends at a constant height, so that a liquid inducted by way of the suction connection is guided in part via the annular gap and undergoes a deflection at the partition wall, cooling the latter before it passes through the rotor passage to the suction inlet.Type: GrantFiled: December 9, 2016Date of Patent: July 2, 2019Assignee: FTE automotive GmbHInventors: Alexander Reul, Markus Dirauf

Patent number: 10337605Abstract: The invention relates to a hydraulic or pneumatic operating device for operating actuators in a motor vehicle transmission. At least two actuation cylinders are provided, each containing a cylinder housing. An actuation piston is guided therein along a cylinder axis in a longitudinally displaceable manner. Each actuation piston can be hydraulically or pneumatically loaded and is operatively connected to one of the actuators. The actuation cylinders are combined into a unit which can be flange-mounted on or in a transmission housing of the motor vehicle transmission. A sensor for detecting the position of a signal element arranged on each actuation piston is associated with each cylinder housing. An electrical interface, which is signal-connected to the sensors, is integrated in the unit, via which interface the sensors can be mutually contacted.Type: GrantFiled: July 28, 2015Date of Patent: July 2, 2019Assignee: FTE automotove GmbHInventors: Egid Macht, Roland Stössel, Reinhold Stöhr, Karin Fecke, Dietmar Fuchs, Alexander Reul, Wilhelm Will, Christian Voigt, Wilhelm Heubner

Patent number: 7644647Abstract: There is disclosed a hydraulic actuating device for actuating a shift rod in particular of a gearbox for motor vehicles, which comprises a cylinder chamber provided in or on a gear housing for accommodating a shift piston which is actively connected to the shift rod and which divides the cylinder chamber into two working chambers which can selectively be acted upon by a pressure medium from a reservoir for the latter, said working chambers being separated from one another by means of a sealing arrangement arranged on the shift piston. The sealing arrangement is designed in a valve-like manner so that, when at least one working chamber is acted upon by pressure medium, it connects said working chamber to an auxiliary chamber which is delimited by the sealing arrangement and which in turn can be connected to the reservoir for the pressure medium.Type: GrantFiled: June 26, 2007Date of Patent: January 12, 2010Assignee: FTE automotive GmbHInventors: Alexander Reul, Roland Stössel, Egid Macht

Patent number: 6883658Abstract: A device is disclosed for the optional engaging and disengaging of a friction clutch for motor vehicles with a preferably hydraulic actuating mechanism, such as a central disengaging device, which, in order to apply an actuating force, is operatively connected with the friction clutch via at least one actuating force transmission member, such as a release bearing, which is pre-stressed in the disengaging direction by means of a spring. The device also has a sensor device with a sensor for sensing a variable representative of the engaging respectively disengaging state of and/or the state of wear on the friction clutch. According to the invention, the force of the spring for pre-stressing the actuating force transmission member or of a spring arranged in parallel with it can be sensed using the sensor, as a variable representative of the disengaging and engaging state of and/or the state of wear on the friction clutch.Type: GrantFiled: May 22, 2003Date of Patent: April 26, 2005Assignee: FTE Automotive GmbH & Co.Inventors: Alexander Reul, Steffen Wöhner, Geza Zsari

Patent number: 6766710Abstract: A hydraulic control device operates a sliding selector shaft, in particular a gearbox for motor vehicles, with a bore made in a wall of a gearbox housing for accommodating a plastic piston. The piston is actively connected to the sliding selector shaft and delimits a pressure chamber and, under hydraulic pressure, radially guides and axially displaces the sliding selector shaft. The piston has a body and a guide section consisting of plastic. The piston is guided directly at the bore, designed as a non-reinforced and unlined cylinder bore, in the wall of the gearbox housing, consisting of a light metal alloy. This creates control device, which is of a much simpler, and more compact design compared with prior art.Type: GrantFiled: June 8, 2001Date of Patent: July 27, 2004Assignee: FTE automotive GmbHInventors: Alexander Reul, Roland Stössel, Günter Kestler
