Patent number: 9638180Abstract: An axial piston machine of swash plate design includes cylinder bores with respective longitudinal axes that are arranged at an acute angle with the rotational axis and that approach the rotational axis radially in the direction of their control plate-side ends. For each cylinder bore, a point of action of a resulting hydrostatic relieving force, which acts on the cylinder barrel, of the hydrostatic sliding bearing is spaced apart radially with regard to the rotational axis of the cylinder barrel further than a point of intersection of the longitudinal axis of the cylinder bore with the cylinder barrel-side bearing face of the hydrostatic sliding bearing.Type: GrantFiled: May 8, 2014Date of Patent: May 2, 2017Assignee: Robert Bosch GmbHInventors: Manuel Sell, Frank Zehnder, David Breuer

Patent number: 9315092Abstract: An articulated device includes a rivet assembly for connecting first and second linkage assembly support arms together at common ends thereof. The rivet assembly includes a blind rivet having a rivet sleeve and a mandrel shaft with a mandrel head. The rivet sleeve and the mandrel shaft extend through first and second bearing holes in the common ends with the mandrel head being on the first arm adjacent to the first bearing hole. The rivet sleeve has a rivet sleeve head on the second arm adjacent to the second bearing hole. The rivet assembly includes a bearing sleeve extending between the rivet sleeve and the bearing holes. The bearing sleeve has a collar-type stop and a shoulder-type shaft stop with the collar-type stop lying against the first arm and the shoulder-type shaft stop lying against the mandrel head. The bearing sleeve has a ring-shaped stop adjacent the rivet sleeve head.Type: GrantFiled: July 28, 2015Date of Patent: April 19, 2016Assignee: Magna Car Top Systems GmbHInventors: Frank Zehnder, Markus Sczuka, Michael Wohlfarth

Patent number: 7798555Abstract: A roof assembly includes a roof having a roof frame with front, center, and rear sections, and a lever assembly. The lever assembly includes three levers which are respectively linked to three swivel axes on the rear section such that the roof is movable between a closed position and an opened position. The first lever connects the rear section at the first axis to a support such that the rear section is movable about the first axis; the second lever connects the rear section at the second axis to the center section such that the center section is movable about the second axis; and the third lever connects the rear section at the third axis to the front section such that the front section is movable about the third axis. The levers are adjacently situated in a transverse direction with the second lever being between the first and third levers.Type: GrantFiled: December 11, 2008Date of Patent: September 21, 2010Assignee: Magna Car Top Systems GmbHInventors: Frank Zehnder, Jan Just

Publication number: 20070063533Abstract: A motor vehicle folding top assembly includes a folding top movable between a closed position in which the folding top is extended along a longitudinal axis and a stored position in which the folding top is compressed. An arched roof bow is connected to the folding top and runs transversely to the longitudinal axis. An adjusting device is connected to the first roof bow and is pivotably connected to the folding top such that upon actuation, while the folding top moves between the closed and stored positions, the adjusting device pivots to move the roof bow and thereby change the degree or direction of arching of the roof bow such that the arching degree in the stored position is less than the arching degree in the closed position or the direction of arching in the stored position is different than the direction of arching in the closed position.Type: ApplicationFiled: September 19, 2006Publication date: March 22, 2007Applicant: MAGNA CAR TOP SYSTEMS GMBHInventors: Frank Zehnder, Thomas Halbweiss
