Patent number: 9333855Abstract: A transfer case for transferring a driving torque of a driving unit of a motor vehicle to a first axle and a second axle of the motor vehicle. The transfer case includes a housing, an input shaft allocated to the driving unit, a first driven shaft allocated to the first axle, and a second driven shaft allocated to the second axle and offset parallel to the input shaft. The transfer case further includes an offset drive for transmitting driving torque from the input shaft to the second driven shaft. The offset drive comprises a gear wheel coaxial to the input shaft or to the driven shaft. The gear wheel is rotatably mounted on a section of the housing.Type: GrantFiled: August 29, 2012Date of Patent: May 10, 2016Assignee: Magna Powertrain AG & Co KGInventors: Markus Krogger, Stefan Leitgeb, Alois Lafer

Publication number: 20100089199Abstract: A torque transfer device for a motor vehicle has an input element, at least one output element, a friction clutch for the setting of a torque transfer from the input element to the output element and an actuator. The actuator includes a drive motor, a reduction gear unit and a ramp ring mechanism. The ramp ring mechanism has at least one rotatable first actuator ring which is made to convert a rotary movement into an axial actuation of the friction clutch. The reduction gear unit has a worm gear having a worm and a spur gear section meshing with the worm, with the worm being coupled to the drive motor and the spur gear section being coupled to or made in one piece with the rotatable first actuator ring. The axis of rotation of the worm is inclined by an oblique position angle with respect to the rotational plane of the spur gear section, with the oblique position angle substantially corresponding to the pitch angle of the worm. The spur gear section has a straight toothed section.Type: ApplicationFiled: October 12, 2009Publication date: April 15, 2010Applicant: MAGNA POWERTRAIN AG & CO KGInventors: Alois Lafer, Robert Luef
