Patent number: 11865908Abstract: A dual transmission with input shafts, output shafts, a transmission case and two separate single transmissions arranged in the transmission case is described. Each single transmission is a two-stage spur gear transmission with three positions for gear centers. A first position is occupied by an input shaft and a second position by an output shaft. A third position is for a middle stationary axle fixed to the transmission case. The three positions define a triangular arrangement having a first side defined by a distance between the first position and the second position, a second side defined by a distance between the first position and the third position, and a third side defined by a distance between the second position and the third position. The second side and the third side form respective angles with the first side. At least one of these angles has a value ranging between 5° and 70°.Type: GrantFiled: July 9, 2020Date of Patent: January 9, 2024Assignee: HOFER POWERTRAIN INNOVATION GMBHInventors: Mathias Lutz, Klaus Kalmbach, Markus Lee, Fabian Kelch

Patent number: 8555508Abstract: A method for producing an internal or external part of a torque-transmitting opposed track joint, such as a fixed constant velocity ball joint, in which approximately axially parallel extending track bases of the joint tracks have curvatures which deviate in their axial course from the curvatures of the ball contact lines. The method is characterized in that in a first step a perform with approximately axially parallel extending grooves having lateral flanks is produced, and in a second step the perform is formed into a final joint part whereby the lateral flanks of the grooves are just partially formed to achieve the ball contact lines.Type: GrantFiled: July 15, 2010Date of Patent: October 15, 2013Assignee: Neumayer Tekfor Holding GmbHInventors: Volker Szentmihalyi, Mathias Lutz, Ekkehard Koerner
